- 10:15 Ethernet AVB standards overview and status
- This paper provides an up-to-date overview of the IEEE Ethernet AVB (Audio Video Bridging) technology and standards. It describes the basics of the key elements of AVB (time synchronisation, bandwidth management, transport layer protocols, etc) and why AVB is an excellent candidate for next generation digital (live) broadcast infrastructures. Also covered in the paper is a summary of the ongoing activities in the various AVB related IEEE working groups including the work on the second generation of AVB (also referred to as Time Sensitive Networking or TSN). Interoperability will be a crucial factor in the success of video networking in broadcasting infrastructures and the paper introduces the AVnu Alliance and its role in relation to AVB standards compliance testing and product certification.Presenter bio: JAN EVELEENS EXECUTIVE PROFILE Axon Chief Executive Officer Jan Eveleens is the CEO of Axon (www.axon.tv).

- 10:45 Internet Protocol Networks in the Live Broadcast Plant
- Data Network Technology has advanced to the point where packet video infrastructure can realistically be considered for different workflows. SMPTE 2022-6 provides full bandwidth video transport in the OSI Protocol Stack and by doing so, further enables the transition from SDI to packets. Encapsulation provides flexibility, extensibility and interoperability not otherwise available with existing SDI baseband video standards. Some argue that the overhead costs associated with encapsulation can be prohibitive for HD-SDI and UHDTV data rates push the cost curve potentially higher. But, these cost curves fall with Moore's Law, and in the long run, the flexibility of using packet video to enable intelligent workflows provides better monetization of content and extends the life of CAPEX investments. Examining the different approaches to facility signal routing and distribution demonstrates the tradeoffs between different network technologies and their suitability for various work flows. Using Ethernet AVB, which includes PTP, is one approach, and COTS IP networks equipment with NTP is another. Using an IP Gateway as part of system design today provides a compelling solution bridging today's SDI with tomorrow's packets. Comparing and contrasting these methods provides insight into their suitability for a given workflow, the costs, and event timelines for implementation. Understanding these timelines is critical to business planning.Presenter bio: After graduating from the University of Toronto in 1982, I worked on high speed data transceiver IC's and hardware for telecom companies in Ottawa, Toronto, and Sacramento.

- 11:15 IP Live Production
- SDI infrastructure has been a fundamental building block for video and audio communications within studios for many years. Meanwhile, the bandwidth of generic IP networks has continued to increase alongside falling costs, such that 10G infrastructure is now commonly available. Exploiting this high-bandwidth commodity infrastructure, an IP network could be deployed in the studio to form an IP Live Production system. This paper explores the technical requirements, design considerations and standards approaches for IP Live Production to be able to deliver business benefits compared to current SDI technology whilst retaining familiar SDI-based production practices. This paper also describes a sample implementation of an IP-based AV router showing how the discussed technologies can be applied to realize the same functionality as a conventional SDI router.Presenter bio: Toshiaki Kojima has worked in both the AV and IT worlds over the past 32 years. He joined Sony in 1982 after graduating from Waseda University, Japan. For the first 20 years of his career he was involved mainly in the design of professional VTRs, from 1 inch to the e-VTR.

- 11:45 IP for contribution broadcasting: the next step of IP ubiquity
- While many rights owners and broadcasters now embrace IP for content distribution, the road has been rockier for IP's adoption for content contribution and production. The enormous bandwidth needed to carry high quality live content and the inherent "best-effort" principle underlying the technology seem incompatible with today's need for real-time, no-downtime content transport. But massive affordable bandwidth is now available and technology exists to overcome IP's risks and limitations, enabling IP's economies of scale, built-in flexibility, lower network operating and capital costs, greater flexibility and ability to push more content. This paper will explore the specifics behind IP infrastructures that include built-in service provisioning, connection management, service analytics, network inventory, and fault-, configuration- and performance-management functions. How to create IP networks—encompassing hardware and software components—that include monitoring and management for resilient, reliable and easily managed systems will be detailed. The paper will also look at specific live-event applications.Presenter bio: Chin Chye Koh holds a Ph.D. and M.Sc. in Electrical and Computer Engineering from the University of California Santa Barbara for work on the perception of visual quality in relation to image and video compression.

How do you know when a signal has been successfully compressed? Easy: you take some measurements and conclude that you've packed more information into less space and nobody has noticed. That's the magic. In this session four experts give us different views of what it takes to get the best from a payload, and we learn that it's as much art as it is science.
- 10:15 Perceptual Video Quality Analysis for HEVC in a Packet Loss Environment
- HEVC provides a significant increase in compression efficiency over legacy standards like MPEG-2 and AVC. As is well known, an increase it the compression efficiency typically results in decreased coding redundancy and subsequently, a vulnerability to error propagation resulting from decoding a coded stream under packet loss (PL) conditions. Here, incorporating/formulating a perceptual Video Quality (VQ) model and analyzing VQ over a range of bit rates, PL profiles and a variety of content; would be of interest. Furthermore, selectively managing the newer HEVC data structure parameters like Tiles etc., to optimize VQ in the aforementioned environment would also be valuable.Presenter bio: Bhupender Kumar is a Principal Engineer at Interra Systems, where he is involved in research and development of advanced techniques for automated assessment of video quality. He has developed algorithms for detection of artifacts due to spatio-temporal discontinuities in video such as video dropouts, defective pixels, blockiness, field order issues etc. His research interests include No-reference video quality estimation, Text detection and recognition, Image/video processing techniques using Computer vision and Pattern recognition and Machine learning. He received his B.Tech. in Electronics and Communications Engineering from National Institute of Technology, Kurukshetra, India.
- 10:45 Improving Video Streaming and File Compression Efficiency without Affecting Quality
- From archiving and cloud storage to video-on-demand, and from production to distribution, bandwidth can be optimized while preserving video quality in a manner satisfactory to the most demanding content owners and viewers. This paper will provide a snapshot into how the efficiency of digital video compression systems may be improved through the use of a pre-processor (before compression) and a post-processor (after compression decoding). The system may include a support layer in parallel with the conventional compression path. The scheme complements conventional compression standards such as MPEG-2, MPEG-4 Video, and HEVC without requiring modifications to the standard codecs. Readers will learn how available network bandwidth can be increased while preserving image quality. Test results will be provided that demonstrate a reduction of bitrates by 35% to 50% using any existing compression system, via the use of processing technologies.Presenter bio: Yves Faroudja has been a major contributor to advanced video technologies for broadcast, digital cinema, and home theater. He has been granted over 75 patents and received three Emmy® Awards, including the Charles F. Jenkins Lifetime Achievement Emmy Award.

- 11:15 State of HEVC Bit Rates in 2014 - Comparing HEVC, H.264 and MPEG-2
- HEVC (also known as H.265) promises to cut bit rates by 50% compared to H.264. But what bit rates are appropriate for different frame sizes, and how does quality compare to H.264 and MPEG-2 in the real world? This paper will provide new and practical data comparing HEVC with MPEG-2 and H.264. It will explore what HEVC bit rates are necessary to achieve quality similar to common H.264 and MPEG-2 distribution formats, measured across sports, news and movies. Measurements from hundreds of test encodes will be combined with an analysis of the features of HEVC, to create recommended bit rates and settings for SD, HD and Ultra HD encoding. This paper continues research presented at NAB 2014, and will present entirely new data for 2014 using the latest encoder technology. This paper will also go beyond SD and HD, with findings and recommendations for Ultra HD encoding.Presenter bio: John Pallett, Director of Product Marketing at Telestream, has over 14 years experience developing and managing computer graphics and digital media software applications for entertainment, CAD/CAM, and 3D design applications.

- 11:45 HDR HEVC Encoder
- This paper describes the challenges and capabilities of an implementation of a high dynamic range layered codec approach for HEVC Main10 4K content for top tier OTT/VOD movie distributors known as "Dolby Vision." While Dolby Vision is already designed to support both AVC (H.264) and HEVC (H.265), the current tools are designed for batch-mode testing with reference-level encoders that generally do not meet the performance and robustness demands of an automated production system. To create a viable production system, particular attention must be paid to optimization and parallelization of the HEVC pipeline to create the final dual layer streams. The production HDR HEVC encoder must also be integrated into the client encoder system application infrastructure, preserving the clients robustness, testability and quality requirements. The final streams must be tested in a similarly performant decoder platform for manual and automated test and verification. Because Dolby Vision is a novel technology that requires specialized hardware for viewing, careful consideration must be given to the visual verification process with a solution that offers powerful viewing tools and defect testability. Finally, the automated decoder verification must test both the backwards-compatible base layer and the high dynamic range enhancement layer. This paper will cover these issues and the technical solutions that were implemented to address them.Presenter bio: Raul Diaz has worked in video compression for over 25 years and has numerous patents in the field. With experience in semiconductors, software and corporate management, he has headed up large R&D teams, helped take a startup public and sold his own company. He heads Vanguard Video developing advanced video codecs used by major companies around the world. Raul has a Bachelor of Science in Electrical Engineering from Yale University.

Developments in Audio Technology, Part 1: Tools for Immersive Audio
Immersive audio has emerged as a powerful force in storytelling. The addition of spatial information enables new creative possibilities that can provide a greater sense of immersion and a higher level of reality to the cinema experience—and before long, to the home as well. This session examines some of the fundamental elements that go into immersive audio, including sound scene description, management of complex sound scenes, and manipulation of object-based sound elements. The techniques and developments described will propel the "suspension of disbelief" that is at the center of the cinema experience.
- 14:15 Cinematic Sound Scene Description and Rendering Control
- Surround sound has been making cinematic storytelling more compelling and immersive for over 30 years. Recently, a new format for distributing and rendering surround sound has been deployed that gives the sound mixer and director new ways to express their story thru sound. The format carries audio elements as well as parameters (metadata) that embody the artistic intent by specifying the translation from the audio elements to loudspeaker signals. In this paper, we present the underlying model for sound scene description and describe how metadata can be used to control its rendering. We illustrate the practical value and application of the format thru analysis of recent movie soundtracks.Presenter bio: Charles Robinson received BSEE and MSEE degrees from the University of Illinois, where he specialized in signal processing and began his professional career just as real-time digital audio signal processing was becoming a practical reality.

Mr. Robinson has authored or coauthored over a dozen patents in audio signal processing, contributed to two Emmy-award winning products, and is a member of AES and IEEE.
- 14:45 Immersive Audio Systems and the Management of Consequent Sounds
- Immersive audio is appearing more frequently in modern cinematic storytelling. In traditional sound mixing, scenarios can occur in which a first sound has a tight semantic coupling to a second sound, for example a gunshot and ricochet, or a handclap and its reverberation. In immersive sound systems, such precedent and consequent sounds may be directed to different locations so as to envelope the audience. When consequent sounds are not managed, the psychoacoustic principle known as the "Haas Effect" can result in portions of an audience misunderstanding the placement of precedent sounds, momentarily disrupting their experience. A series of immersive sound examples demonstrates the resulting problem and the effectiveness of a proposed management technique, applicable to object-based, wave field synthesized, and ambisonic reproduction.Presenter bio: Started his career mixing technology and entertainment by pursuing a Masters Degree in Engineering at UCLA while building practical electronic props for Battlestar Galactica and Buck Rogers.

His favorite two: A roller coaster you design then ride, and a keyboard for dolphins to communicate with people, and both really worked.
- 15:15 Object-Based Audio: Opportunities for Improved Listening Experience and Increased Listener Involvement
- A new TV audio system based on the MPEG-H Audio standard is being designed and tested to offer interactive and immersive sound, employing the standard's audio objects, height channels, and Higher-Order Ambisonics features. Object-based interactive audio offers users the ability to personalize their listening experience, setting their preferred language and dialogue level, or selecting elements to "hear their home team" or listen to their favorite race driver's radio. A four-stage process is introduced for implementing the complete system in TV networks. Additionally, the plant design, creative, and operational implications of producing content are discussed, based on the design and field testing of the system. Consumer reproduction implications are also presented, such as a "3D Soundbar" prototype, the control of loudness in the system, and rendering for playback on both traditional and new media devices.Presenter bio: Robert Bleidt is General Manager of the Audio and Multimedia Division of Fraunhofer USA Digital Media Technologies.

- 16:15 Network Delivered References - Under the Hood and Across the System
- The SMPTE ST 2059-1 and -2 Standards will enable IP network delivery of all of today's reference signals to media equipment. This paper first explores how the IEEE-1588 Precision Time Protocol is used to deterministically generate the same signals as used today. Next, how the master works SMTPE-specific ways, and how terminal equipment converts network precision time into real or virtual SMPTE (and other) reference signals is discussed. How the new PTP (grand)master behaves with respect to existing discrete-signal master generators is then examined, leading to an overview of the evolution of legacy systems to incorporate network reference. These systems are described in detail in terms of maintaining interoperability as equipment and facilities repurpose and evolve, and all-IP systems using network reference are also described. Finally, the paper looks at a use case of seamless evolution of a facility from HDSDI and discrete reference signals to all-IP reference and media transport.Presenter bio: Paul Briscoe Bio Paul began his career in the broadcasting industry in 1980 at the CBC in Toronto.

- 16:45 Generating synchronous video signals from just time
- The concept that a video generator can create a synchronous ("genlocked") output signal with only the knowledge of the correct current time seems radical to many. Yet SMPTE is preparing to publish a pair of key standards which define exactly how to do just this. This paper will explain the background and the methodologies being used to permit what may become the most important transformation in the history of television - the move from coax to Ethernet.Presenter bio: A 35 year veteran of the broadcasting industry, Mr. Waddell is a SMPTE Fellow and is currently the Chair of the ATSC's TSG/S6, the Specialist Group on Video/Audio Coding (which includes loudness).

He is also a member of the IEEE BTS Distinguished Lecturer panel for 2012 through 2015.
- 17:15 PTP deployment in Large Networks - Traps and Pitfalls
- The IEEE 1588 Precision Time Protocol (PTP) is a proven method to distribute highly accurate time information over Ethernet networks allowing devices to synchronize their clock to a common time source to less than 100ns. Deploying and operating PTP in large networks with a high number of PTP nodes with differing demands for synchronization accuracy requires detailed planning of the network topology itself. If the network infrastructure is shared with other applications, especially those with considerable bandwidth demands, the PTP performance will be impacted. PTP precision relies on the optimal configuration of all network devices as well as the appropriate settings of all relevant PTP parameters. The principles for designing and configuring large broadcasting networks are described together with PTP performance optimization techniques. The benefits and efficient use of PTP enabled network devices are covered as well. For typical network topologies, measurement results show the effect of individual optimization tasks.Presenter bio: After receiving a Masters Degree in Communication Engineering with distinction from the Vienna University of Technology, Nikolaus led the ASIC design division at the university's Institute of Industrial Electronics, successfully managing numerous research projects and industry collaborations.

Developments in Audio Technology, Part 2: Delivering on the Promise
New audio services represent new opportunities for content producers, and new ways of enjoying programming for consumers. This new technology, of course, is of little value if it doesn't find its way through the long and sometimes very complex chain that stretches from the microphone on the stage to the speakers in the home. This session examines some important elements that comprise parts of this chain, including interchange, distribution and delivery of immersive audio; a detailed examination of loudness vs. speech normalization; and methods of reducing audio transmission impairment. Designing an advanced audio system and getting it to work efficiently in a wide variety of applications is a major challenge. Join us as we examine ways to address this challenge.
- 16:15 Immersive & Personalized Audio: A Practical System for Enabling Interchange, Distribution & Delivery of Next Generation Audio Experiences

- 17:15 Digital Audio Transmission Impairment and Link Failure: Test Data, and Recommendations for Improved Industry Standards and Reference Designs
- Broadcast and cinema applications for digital audio transmission with sample rates (FS) over 48 kHz (e.g. FM digital composite) have experienced signal dropouts and link failures over cables longer than 30 m. Engineers may assume that digital transmission works, regardless of source, cable, destination or sample rate. The cables, interface ICs, EMI filters and components for digital audio transmission are designed according to AES3-4, AES2id-2012 and ANSI/SMPTE 276M-1995 standards. The paper presents field observations and test results for 100 m lengths of many types of balanced and unbalanced cables at FS 48-192 kHz, revealing huge variations in cable transmission and received spectra and eye-patterns. The author includes a review and recommendations to update the standards for sample rates, rise times, bandwidths, eye pattern masks, and circuit designs, to apply to higher transmission rates. The result will be improved and more reliable signal transmission for all sample rates and cable lengths.Presenter bio: Jon Paul is from Manhattan. He has an MSEE from City College of New York.

- 10:00 HEVC efficiency assessment for contribution services of interlaced content
- In January 2014 a new family of HEVC profiles named "Range Extensions", have been approved in order to cover the needs of high quality production environments, such as primary distribution, contribution services, and edition/post-production. The new "Main 422@10" profile will become the successor of the successful "Hi422P" profile of the H.264/AVC, achieving a high efficiency for emerging formats beyond HD, such as the 4k and 8k formats. However HD interlaced content is nowadays the mainstream for broadcasting production, but HEVC profiles do not include specific tools for interlaced content as H.264/AVC did. This paper addresses the issues involved in HD interlaced contribution services under HEVC "Main 422@10" profile, with the aim to identify the true HEVC efficiency compared with Hi422P profile of H.264/AVC. The simulation results will report the bandwidth saving and the quality improvements, that broadcasters and network operators can achieve for HD interlacing encoding using new HEVC profiles.Presenter bio: Damián Ruiz Coll received the M.S. degree in Telecommunications Engineering from Polytechnic University of Madrid (UPM), Spain in 2000, and the Ph.D. in Computer Science from UCLM in 2015.

Dammit, Gamut, I Love You!
This session looks into the challenges of extending the color gamut and dynamic range for next generation imaging systems including UHDTV. Issues such as how to maintain creative intent, how to color match between HDTV and wide gamut UHDTV displays, how to assess the quality of color conversions and how to view the results of color and dynamic range conversions.
- 08:30 Color management for wide-color-gamut UHDTV production
- UHDTV is a wide-color-gamut system, as standardized in Recommendation ITU-R BT.2020 and SMPTE ST 2036-1, that covers most real object colors and encompasses the gamuts of HDTV, Adobe, and DCI-P3. The development of wide-gamut displays and high-quality gamut mapping are major challenges in the workflow of UHDTV production today. While monochromatic light sources, such as lasers, are ideal for UHDTV wide-gamut displays, wide-gamut LCDs with non-monochromatic backlight sources, such as quantum dot LEDs, may well be used from the viewpoint of both cost and performance. Furthermore, a high-quality gamut mapping algorithm between UHDTV and HDTV for live broadcast production is essential. This paper offers solutions to these challenges.Presenter bio: Kenichiro Masaoka received his B.S. in electronics engineering and M.S. in energy engineering from the Tokyo Institute of Technology, Japan.

- 09:00 Quality Assessment Framework for Color Conversions and Perception
- Gamut conversion has become an important topic in the audiovisual industry. As larger gamut and higher dynamic range are introduced it seems necessary to provide fast and high quality gamut conversion methods. The objective of a gamut conversion should be to provide to the audience a perception of the program carrying the same artistic intents than with the initial working display. Perceptual facts as well as perception variability for a given display must also be taken into account. Built on a preceding research on quality framework, a measurement structure for the evaluation of gamut mapping is presented. It results in a measurement vector allowing color comparisons between two rendition channels.Presenter bio: Background in Mathematics, Semantics and Film making, 30 years of experience in Professional Video and Film, Started as video artist.

- 09:30 A better color matching between HD and UHD content
- The introduction of a wide-gamut color space in Ultra-HD television creates a need to match colors on wide-gamut UHD displays with colors on conventional HD displays. Many contemporary color conversion methods that apply to conversion from HD to SD, and color conversion methods mandated by current television standards, fail to produce a good color match when converting colors from HD or narrow-gamut UHD color spaces to the wide-gamut UHD color space. This paper illustrates the color errors caused by the application of several of these conversion methods, and recommends one method, using display-referred colorimetry, for better color matching between narrow-gamut and wide-gamut displays.Presenter bio: Lars Borg is a principal scientist in digital video and audio engineering at Adobe.

- 10:00 High Dynamic Range Intermediate
- There is a need to exchange high dynamic range wide gamut moving images that embody creative intent. Simple definitions using CIE 1931 chromaticity having extended gamut may not suffice. It may be desirable to extend gamut beyond P3, even for material mastered using P3 displays and projectors. It is also clearly useful to master to a dynamic range that may exceed a given mastering device. Reduced gamut and dynamic range used temporarily during mastering provides a means of checking image integrity outside of device gamut and range limits. However, additional information about mastering emission spectra is also useful, yet is difficult to interpret as gamut widens further. This paper seeks to explore these issues, and to propose approaches to defining an HDR Intermediate that can be exchanged with increased confidence with respect to creative mastered intent.Presenter bio: Gary Demos is the recipient of the 2005 Gordon E. Sawyer Oscar for lifetime technical achievement from the Academy of Motion Picture Arts and Sciences.

Cinema Workflow - A Brief Moment in Time
Fans of the new TV series Cosmos will agree the producers have presented the vast intricacies and marvels of our universe in a remarkably engaging and understandable way. Physicists have gained very high level and consistent knowledge of the incredibly complex mechanisms of nature over the last decade.
Ah, if only Cinema Workflows were as simple to understand…It kind of reminds us of Dark Matter - We know it's there. We know it affects us in innumerable ways. And we can't consistently describe its attributes or how it affects everything else around it. Further, just like our knowledge of the universe, Cinema Workflows are ever-changing; giving new challenge to our skills and understanding of the process.
In this session, our presenters will help us explore and better understand a few the "Dark" areas of Cinema Workflow. And hopefully, in the end, we will be one step closer to a "Unified Theory" of Cinema Workflow.
- 08:30 Camera Raw Workflows - Like Film, but Digital
- If you liked working with film, then the techniques to control exposure will feel very familiar to you in camera raw formats. This paper presents how all camera raw formats work in common, and also the different approaches used by several vendors to preserve the highest fidelity image information, while managing the large amounts of data required to represent those images. Camera raw workflows provide a variety of techniques to convert from the sensor data into RGB and YCbCr image formats suitable for mastering, along with methods for generating a specific "look" to the images. Similar to film, the tremendous dynamic range afforded by a camera raw format permits a wide range of exposure during acquisition, which must be mapped into the limited dynamic range of the final output formats in the workflow.Presenter bio: Edward Reuss is an independent consultant specializing in video, audio and Wi-Fi networks, particularly for very low latency applications.

- 09:30 Options for Camera Raw in the Digital Workflow
- Raw camera data is an important component in the digital workflow. But, with higher resolution, the ability to get all of the sensor information out of the camera is challenged by the speed of existing interfaces. Additionally, the cost of storing this data for a high shooting ratio projects is cost prohibitive. This paper explores the workflow options that are available for compressing Bayer/Mosaic Pattern data. Topics will include the data layout of the Bayer Pattern for specific cameras resulting in interface speed requirements for different resolutions, compressibility of Bayer Pattern data vs. Debayered DI images (entropy differences between Camera Raw and DI images and the impact on Compression Ratio), dynamics of uploading Camera Raw from On-Set to the Cloud, and options when applying compression at various stages of the Production and Post Production workflows.Presenter bio: Keith Hogan is the CTO for Pixspan, where he develops technology for making high resolution images as small as possible.

File Based Workflows - Part 2: Meaningful Media Management - Taking Us to the Second Screen and Beyond!
As our workflows extend to other devices and second screens, we need to get an even better handle on managing our media. This session will start with a method of facilitating complex workflows by first identifying our media in a meaningful manner. From there, this session will expand and explore the management and migration of media to other devices and second screens.
- 11:00 Identifying Media in the Modern Era - The Domains of Media Identity
- Identity is the property of an object that distinguishes it from all other objects within a domain, a domain being a physical or logical system by which objects are bounded. Objects may exist within many domains simultaneously, however the object must posses an Identity for each domain to which it is bound. Media, like any other object, may also be bound to many domains, each domain representing or defining some aspect of that Media. For instance, Media can exist within a physical domain where each Media instance represents a unique physical asset or file, while simultaneously belonging to a logical domain in which each Media instance represents a dataset describing a unique set of sights and sounds, without a physical representation. These Domains of Media Identity define the relationships that connect real world events to physical Media and provide the various groupings required to facilitate complex Media workflows.Presenter bio: Steven Posick, associate director, Enterprise Software Development, joined ESPN in 1995. He is a veteran senior systems architect, designer, developer, and security professional, with more than 24-years-experience in Information Technology and a 10 year focus on Media: Identity, Management, and Control.

- 11:30 Today's smarter workflow: managing and delivering assets to all devices
- The media landscape, with second-screen and online delivery increasingly significant, has changed dramatically. Along with these changes comes the need to fundamentally alter media asset workflows. Managing content from a central repository, where operators can produce files for broadcast, mobile and web on one seamless workflow is the future. This paper will detail how integrated web-based technologies allow asset delivery to any platform in one workflow, enabling content packaging and optimized delivery speed while wrapping in branding and graphics. We'll show technologies that allow content updating right up to the point of transmission, empowering journalists' creativity. Techniques such as storing the edit decision list (EDL) and graphic information as metadata, with the video and graphics playlist then sent to the control room, with the final piece played back in real time on-air - automatically sized and distributed online and to mobile devices - dramatically save storage space and time.Presenter bio: In 1999, Hersly established what is now the Vizrt Americas organization. Prior to that, he was President and COO of a publicly traded company that developed graphics and similar production tools for the broadcast market. Until 1986, Isaac was VP Engineering of the ABC owned television stations.
- 12:00 Remote Content Access and the Rise of the Second Screen"
- Technological advances are allowing operators, editors and producers to remotely access media production servers for content editing and repackaging for distribution and archiving - in real-time, anywhere in the world. Advanced remote production gives unprecedented capability to work remotely, enhance content on the fly, and deliver original content to users' second screens. The paper will analyze the technology, challenges, results, and opportunities behind new capabilities that are changing the media landscape. Real-world examples, including multimedia distribution for the 2014 FIFA World Cup—delivering live streams, multi-angle clips, stats, and social network feeds to viewers' connected screens through broadcaster apps—will be explored. The complex World Cup workflow, encompassing live streaming of six HD camera angles and up to 24 multi-angle replays instantly pushed to a central cloud-based platform, access to 3,000 hours of stored content, on-the-go transcoding and distribution to FIFA's Media Rights Licensees (MRLs), drives an estimated 50 million downloaded apps.Presenter bio: James has more than 20 years of industry experience in facility design and integration, mobile satellite communication, and mobile TV production, with roles that had him overseeing several major technology transitions, including the move from traditional video production to the world of file-based workflows and technologies.

Higher Frame Rates
This session will address the question, "Is Faster Better?". The papers will walk us through the challenges, benefits and solutions when working at frame rates beyond 60Hz, including both video and "HFR" cinema formats. It will address frame rate conversion from 120fps to 50, 60(59.94), and 100 fps video formats, as well as 60, 30, and 24 fps d-cinema formats.
- 11:00 120fps as a Universal Production Format for Motion Pictures
- HFR (High Frame Rate) has emerged as a release format for movies like The Hobbit, Avatar 2, and others. This paper presents a method of photography compatible with release in multiple formats, including standard 24 and 30fps in addition to HFR. The paper describes a technique to enable artifact-free output of 60fps, 30fps, and 24 fps masters from the same original photography. In addition, the method also allows the selection of the desired effective shutter angle after principle photography is completed. In this way the creative team can trade off different levels of temporal aliasing versus motion blur on a scene-by-scene basis, should any problems show up in Post.

- 11:30 High Frame Rate Video Conversion
- SMPTE is discussing high frame rates within the UHDTV Study Group, and in particular, conversions from high frame rates to today's integer and fractional standards. Although it seems an easy problem to up and down convert between frame rates when there is a simple multiplier e.g. between 119.88Hz and 59.94Hz, in this paper, we show that adequate quality results cannot be obtained by simple frame doubling or frame dropping. We present a high quality, low complexity frame rate conversion method, suitable for all high frame rate conversions e.g. 120Hz to 59.94Hz or 50Hz to 120Hz, thereby obviating the need to include fractional frame rates in the UHDTV standard.Presenter bio: Paola Hobson has extensive experience in communications and media industries, including public safety and consumer mobile products, and professional broadcast systems.

- 16:15 Utilizing Unique Information from File-based Media for Automated File Detection
- Currently, there are no reliable and automated methods to recognize program boundaries and accurately identify program content for the purposes of loudness measurement, air-checks, competitive analysis, etc., while not overlapping or including portions of adjacent programs (primary media content) or other commercials (secondary media content) that will skew the results and render them unreliable. The author proposes a reliable and automated method utilizing accepted broadcast methodologies and approaches in addition to innovative out-of-band data carriage methods to accurately detect and identify programs, providing a method to reliably discriminate between primary media content and secondary media content for the purposes of loudness measurement, competitive analysis and other common broadcast tasks. The carriage of data using out-of-band techniques eliminates the risk of reverse engineering or hacking and can be leveraged to carry other types of data useful for broadcasters to achieve a high quality of service for both viewers and program partners.Presenter bio: As the Senior Professional Support Manager at Dolby Laboratories, Mike Babbitt works with content providers, operators, networks and local stations to create, deploy, implement and understand the use of Dolby technologies and multichannel audio programs based upon their specific infrastructure and transmission requirements, as well as helping post production professionals understand and navigate network delivery requirements for broadcast content and implement Dolby technologies for both standard and high definition packaged and OTT media.

- 16:45 Have things calmed down?
- Engineers are familiar with the Law of Unintended Consequences. This presentation tells the story of several unintended consequences related to audio which are in play today. The transition to digital delivery systems liberated audio from less than 40 dB of dynamic range. The creative community has been exploiting that increased dynamic range. That is the good news, but it is also the bad news. Without standards in place for digital operating points, sound mixers and producers have used levels varying over at least 30 dB. This has created consumer irritation. The industry realized these issues needed to be addressed. Some time ago, both the ATSC and the EBU established groups to provide guidance to the content creators and system operators. This presentation provides an assessment of both the ATSC and EBU documents and similar work done in other regions.Presenter bio: A 35 year veteran of the broadcasting industry, Mr. Waddell is a SMPTE Fellow and is currently the Chair of the ATSC's TSG/S6, the Specialist Group on Video/Audio Coding (which includes loudness).

- 17:15 The Origins Of Audio and Video Compression: Some Pale Gleams From The Past; A Historical Perspective On Early Speech Synthesis and Scramblers
- The paper explores the history that led to all audio and video compression. The roots of digital compression sprang from Dudley's speech VOCODER, and a secret WWII speech scrambler. The paper highlights these key inventions, details their hardware, describes how they functioned, and connects them to modern digital audio and digital video compression algorithms. The first working speech synthesizer was Homer Dudley's VOCODER. In 1928, he used analysis of speech into components and a bandpass filter bank to achieve 10 times speech compression ratio. In 1942, Bell Telephone Laboratories' SIGSALY was the first unbreakable speech scrambler. Dudley with Bell Labs, invented 11 fundamental techniques that are the foundation of all digital compression today. The paper concludes with block diagrams of audio and video compression algorithms to show their close relationship to the VOCODER and SIGSALY.Presenter bio: Jon Paul is from Manhattan.

- 09:00 LTFS Transforms LTO tape into Nearline Storage: Accelerating 4K Media Workflows
- With increasing amounts of 4K content in digital file-based workflows, LTO tape has emerged as a cost-effective way to store raw, 4K content. However, LTO tape is typically an offline, non-accessible archive medium, and data on LTO must be restored prior to use. Restoring immense amounts of high-resolution data (UHD, 4K+) from LTO causes a bottleneck in file-based workflows. With LTFS technology, it is possible for applications to obtain free, open and direct access to content on LTO tape. This "disk-like", direct access nature of LTFS can transform LTO tape into nearline storage for new and faster high-resolution media workflows.Presenter bio: Tridib Chakravarty ("tC") possesses deep knowledge of the storage and archiving industry and he is responsible for the overall strategy and vision of StorageDNA's product line.

- 09:30 Concept for a File Based Content Exchange Ecosystem using Scalable Media
- We introduce a concept of a file delivery ecosystem, exploiting the features of scalable (hierarchical) media like JPEG 2000. The innovation of this concept is the possibility that the recipient may start to work with the transmitted content even before completion of the transfer due to the scalability feature. For this, a reduced sub-variant from the scalable sources will be transmitted in the first phase until the whole sequence reaches its destination and the recipient is able to get a preview. Subsequent phases will add more and more information to the sub-variant transmitted in the first phase. Due to a concept called Substitution Strategy — which has been presented at ATC 2012 — the software running at the destination is able to rebuild the file-structure of each file and to simulate the remaining data so that the images can be used for further processing before the overall transmission is completed.Presenter bio: Heiko Sparenberg, born in 1977, received his Diploma degree in Computer Science in 2004 and a Master degree in 2006.

- 10:00 A Holistic Approach to Digital Preservation
- Migration-based preservation strategies do not address the underlying need for securing data integrity and future access of valuable data. EU and the Norwegian Research Council have funded three pan-European R&D projects developing a turn-key solution with all components needed for writing, storing and retrieving digital data. The result converts photosensitive film into a digital storage medium, just like it was done with magnetic tape. Binary codes are written on a medium with proven long-term qualities, and digital data can be stored alongside images and/or readable text. The materials have undergone longevity testing by IPI, and technology source codes are open.Presenter bio: Bjørn H. Brudeli is an B.Eng of Data/Telecommunication and B.Eng in Media Technic.

IP Streams: Control, Monitoring and Production
This session presents a spectrum of use of IP in broadcast: from video streams, to control & monitoring, and in applied real-world use in remote production.
- 08:30 0ff-the-shelf IP Routing Switchers in the Hybrid IP/SDI Television Broadcast Environment
- With the trend to IP streams as a key part of the broadcast environment, IP routing becomes an essential component. Off-the-shelf IP Routing Switchers are agnostic and transparent to transported media allowing any transport streams, codec types, and uncompressed media, and provide longevity of router investment with changing standards and formats. The challenges of an asynchronous system where timing is distributed but signals are not co-timed can be met with the required media processing, clean switching , synchronization broadcast services all at the system edge. This type of infrastructure can be operated alongside existing SDI systems and controlled with traditional broadcast control services in a seamless operational environment.Presenter bio: Martin Holmes is the Vice President of Technology at Snell.

- 09:00 The Control of Media within an Internet of Things using SMPTE ST2071
- The "Internet of Things" (IoT) refers to an Internet like structure consisting of uniquely identified objects that expose services. These services are typically designed using traditional Object Oriented methodologies that encourage the coalescence of features into a single consolidated view. This may work well for homogeneous environments but can be problematic for heterogeneous environments, such as media control systems, where objects may be modular and change their behavior dynamically at runtime. To better represent objects within these environments, and the IoT, the SMPTE ST2071 standard allows objects to be described using sets of uniquely identified features, known as Capabilities. Capabilities can be used in much the same way as building blocks to construct object behaviors and the objects can change their behavior dynamically by changing the set of Capabilities exposed. In addition, the use of Capabilities also allows objects to be discovered within the IoT by the features they support.Presenter bio: Steven Posick, associate director, Enterprise Software Development, joined ESPN in 1995.

- 09:30 Monitoring Video Services in an IP Connected World
- Applying traditional methods of video service monitoring to highly evolved and changing delivery methods to customers using all manner of viewing devices anytime/anywhere just doesn't work. Video service monitoring must evolve with video service delivery methods in a reasonable, cost effective, scalable manner. This paper examines how to approach monitoring in next generation IP-enabled services such as CloudTV, cDVR, and cVOD and how to take advantage of the new architectures being deployed. It will examine what issues will be encountered using a traditional monitoring and data collection approach. It will then look at alternative approaches using new paradigms on what to monitor, how to monitor it, and what data not to store. We propose that doing less checking of individual faults and shifting more towards system health monitoring of the data network through automated testing strategies will be a way to proactively handle multiple potential faults at the same time.Presenter bio: Chuck has had a varied career in many aspects of service delivery, from operations and maintenance to systems engineering and installation to his current role in Applied Research at Comcast.

Advancements in Theatrical Display
Cinema projector technology is currently undergoing a period of dramatic innovation. Rather than using traditional xenon short-arc lamps, new laser illuminated projector systems are being developed to provide enhanced images, including an expanded image dynamic range and wider color gamut. This session will explore how laser illumination holds the potential for blacker blacks and brighter highlights, as well as practical limitations of the technology. You will learn how laser light can be used to expand the color gamut, and the impact of metamerism in the perception of color. Laser speckle is an undesired attribute of this new technology, but measuring speckle is challenging. You will learn the latest advancements in speckle measurement techniques necessary for image quality assurance. In addition, this session will include a presentation on the findings of an important new study on viewer preference, which explores the perceptual impact of expanded image dynamic range in the cinema.
- 08:30 Viewer Preferences for Cinema Luminance Dynamic Range
- Recent studies on viewer preferences conclude that viewers are looking for increased display capability, with several groups finding preferences toward higher dynamic ranges on small screens. One study found a luminance range of 0.005 to 20,000 cd/m2 (22 stops) just met the preferences of 90% of the viewers. In translating results from small screen to larger cinema screens, it is assumed that the preferred cinema brightness is much dimmer. This assumption, however, includes multiple confounding aspects (e.g., illumination of the audience, field of view). We have studied viewer preferences for the cinema isolating luminance range from other factors. Using a 6kW cinema projector, and a 13 foot 2.8-gain screen, we produced a maximum screen luminance of 2,500 cd/m2, and concluded that 22 stops of dynamic range (twice the dynamic range of existing cinema), would meet the preferences of all but the upper 10% most critical.Presenter bio: Suzanne is a software engineer for Dolby where she has focused on carrying out viewer preference studies on image quality. She graduated from Rochester Institute of Technology with a degree in Motion Picture Science.
- 09:00 Development of an Accurate and Repeatable Measurement Method for Speckle in Laser Illuminated Projectors
- With the emergence of lasers as a replacement for xenon arc lamps in ultra-high brightness digital projection applications, it is desirable to preserve the best possible image. Speckle is one aspect of image quality that has been the subject of recent attention. It is fundamentally difficult to measure, due the unique physical characteristics of coherent light and the absence of a single focal plane for the speckle image. This paper describes the development of a speckle measurement method, with reference to work recently completed by the Laser Illuminated Projector Association (LIPA). The identification of obstacles to measurement, along with explanations of how each was managed, will be of interest to those who will measure speckle, and for the science of image quality metrology in general. Ultimately the addition of speckle to the industry's current suite of image quality measurements will promote the successful deployment of lasers for high-quality theatrical projection.Presenter bio: Rick Posch is owner and CTO at CR Media Technologies.

- 12:00 Applying AXF Tools from the Set through Production Workflows
- The Archive eXchange Format (AXF) was developed to enable multiple files to be treated as a unit for operational storage and longer term preservation purposes. To support such applications, methods were developed to establish hierarchical relationships between files through use of folders established in the AXF structure. There also is an extensive set of metadata that is useful in managing and documenting the files stored in AXF Objects. As the tools defined by AXF became understood by end users, it became apparent that those tools offered solutions to file management and documentation needs throughout the production workflow, starting on the set. Through a simple, straightforward modification of the XML schema that underlies AXF, it is possible to create manifests of files that carry file metadata needed throughout the workflow all the way to the archive. In essence, use of AXF tools upstream of archives permits application of AXF in "unwrapped" form, with the files being "wrapped" into AXF Objects for archival purposes when desired. The paper will describe upstream applications of AXF and the modifications of the AXF schema necessary to enable those applications. Work on creation of a standard for upstream use of AXF tools is under way in SMPTE.Presenter bio: S. Merrill Weiss is a consultant in electronic media technology and technology management.

Content Accountability, Tracking and Protection
The focus of our supply chain is geared toward producing content and the distribution of the said content to consumers. Along the way, we need to ensure that the content is secure, and especially more so when considering highly collaborative workflows, geographically dispersed workgroups, and production in the cloud. Additionally, when the content is consumed it is vitally necessary to have accurate monitoring on where, how and when it is consumed.
This session brings together these vital aspects in three papers. The authors of the first paper will discuss the modalities of media management and measurement. The second paper will discuss how piracy can be curtailed using forensic watermarking, and finally, the last paper, will bring us solace by letting us know that knowing that while cyberattacks will occur, we can survive them by making our production pipelines cyber reliant.
- 11:00 How Do We Measure Up?
- When it comes to media, measurement is what it's all about. We are all in the business of monetizing our media assets, but without accurate measurement of their consumption, we really can't do a good job of this. 2014 has seen some very important advances in technologies that enable not only the management, but also identification, and measurement of media consumption. SMPTE is standardizing the representation of Ad-IDs and EIDRs, as well as how to handle those in MXF files. They are also working on the embedding of these identifiers in content in such a way that it can survive all means of transformation and distribution to viewers. Couple this with work that has already been done, and we are on the cusp of having a very powerful toolset for media management and measurement.Presenter bio: Chris Lennon serves as President & CEO of MediAnswers.

- 11:30 Toward Real-Time Detection of Forensic Watermarks to Combat Piracy by Live Streaming
- Over the past several years, anti-piracy analysts have documented the transition of casual content piracy away from Torrent networks to streaming sites which provide immediate access to not only live TV broadcasts, but also file-based pirated content, such as movies and TV episodes. Since Live Content such as professional sports or Pay Per View events have only one release window, they will lose market value immediately if they can be streamed live, thus there is a recognized need to act quickly in the case of piracy and hence to shorten the time needed to extract the forensic watermark payload to as close to real-time as possible. In working toward inline detection of forensic watermarks from streaming content, we seek to enable a new tool designed to identify the pirate source in minutes. With the ability to detect a session-based forensic watermark directly from a video stream, it is possible for an operator to disable a set-top box or streaming client while the transmission is still in progress. • For pay TV and online content distribution: the latest applications of its session-based watermarking in the head-end, on the CDN edge, and in the end consumer's devicePresenter bio: Ken Rudman has over 15 years’ experience in product development, product management and product marketing, primarily in video content distribution, search and advertising.

- 12:00 Not every Cyber attack can be stopped, but they can be survived
- The entertainment supply chain is evolving, and will utilize more public "cloud" infrastructure as content developers find more seamless collaboration and time condensing solutions. Divergence from air-gapped/isolated networks will indeed provide this efficiency, but with a potentially hidden cost. With critical assets moved into a more publicly accessible network, breaches of security resulting in theft or disruption of production processes become a more likely scenario. At this critical point between architectures, organizations must identify where attacks can occur, how information may be exfiltrated, and how to minimize damages. Organizations must be operationally prepared for rapid response. This is cyber resilience.Presenter bio: Chris Morales, Practice Manager, Architecture and Infrastructure, has over 17 years of IT and information security experience and joins NSS from 451 Research where he was Senior Analyst, Enterprise Security.

Image Processing Part 1: Methods for creating high quality images beyond HD
Displays today are able to reproduce higher resolutions, higher frame rate and higher dynamic range than ever before. The question is how we can generate, up-convert or preserve high quality images from image acquisition up to the display. In our first presentation a new algorithm for improving the edges in images will be presented. It can be used for up-converting or sharpening of images. Our second presentation takes care of the issue that motion during capturing of images can destroy a high resolution and will give recommendations how to preserve the details. The third presentation will cover the question which imager technology is available today and how it can be used in different production and delivery workflows.
- 14:00 Real Time Super Resolution for 4K/8K with Non-linear Signal Processing
- 8K and 4K systems may be the ultimate in high-resolution video, but the imaging, editing and transmitting equipment is insufficient in resolution to fully express the vast capabilities of 4K/8K displays. Although many image enhancement technologies exist, they merely emphasize the edges already in the original image. Our novel super resolution technology uses non-linear signal processing to create naturally appearing thin edges that do not exist in the original image and frequency elements exceeding even the Nyquist frequency in real time. Besides its use to up-convert existing content, it can be used during production to solve the problem of defocusing. Delivery method: presentation and video clip. The demonstration will be held in the booth of Keisoku Giken. Keisoku Giken is going to have a booth in SMPTE 2014.Presenter bio: Seiichi Gohshi is a professor of Kugakuin University.

- 14:30 4K: Model for motion control to ensure true 4K detail at capture
- The advent of 4K bears the promise of a resolution 4 times larger than 2K Digital Cinema. For images to take advantage of this increase, capture systems must be configured and operated to maximize detail. One of the critical components for maintaining image detail is motion blur, dictated by optical flow (motion, as seen by the sensor) and shutter speed (to ensure smoothness of motion). In this paper, the author defines mathematical models and practical methods to optimize motion during 4K capture and provides several examples and tips based on his experience from actual productions on how to achieve true 4K detail.Presenter bio: Former Aerospace Engineer Pierre Hugues Routhier, Eng., M.Eng., is a specialist in advanced imaging technologies.

He is credited with more than a dozen patents related to advanced imaging and is published in several industry papers. He is currently working with major studios and broadcasters on production, research and training related to advanced imaging.
- 15:00 Beyond HD - The status of the image acquisition solutions for the next generation broadcasting formats
- Many discussions inside the broadcasting community are focused on next generation broadcast formats. For content producers and distributors, the question remains, "what will be the best solution for the next generation broadcast format?" Is it just the double pixel count in horizontal and vertical directions? Will a higher frame rate and/or a higher dynamic range and extended color range provide viewers a higher value? Or which combination of these improvements needs to be included in a next generation broadcast format? The answer will likely depend on the type of production and/or content delivery. All these points have a direct influence on the imager technology and the paper explains the different potential solutions of "4K" or UHD image acquisition including their strength and limitations with the focus on live broadcast productions.Presenter bio: Klaus Weber is responsible for the worldwide product marketing of the imaging products for Grass Valley a Belden Brand.

Image Processing Part 2 - Reducing distortions in captured images
Image capturing is always restricted by physical and technological limitations. This can be the sampling process or the existing capture and storing technology at the time of capturing. The first presentation will investigate the influence of sampling to the quality of later displayed images. The second presentation will demonstrate what image quality can be reconstructed by today's technology from images captured and stored 40 years ago during the lunar orbiter missions.
- 16:00 A psychophysical study isolating judder using fundamental signals
- There are a number of well-known observations of movie content being displayed at different frame rates. While the terms are not entirely solidified across the industry, there are 4 main degradations of the signal as compared to unsampled motion (i.e., real-world motion). These are: 1.non-smooth motion (which is also most often referred to as judder, or strobing), 2.The appearance of false multiple edges ), 3.flickering (a counterphase spatiotemporal frequency along moving edges), and 4.motion blur In natural imagery, all four of these effects generally appear to the viewer. The spatiotemporal window of visibility [ref: Farrell, Watson, Ahumada] has proved successful in describing when motion looks distorted from the real-world smooth motion. However, that model allows a prediction of detection performance, but doesn't address the appearance or magnitude of motion distortions. In addition, there are also well-known image capture and display parameters involved with frame rate questions, such as exposure duty cycle (shutter angle), object speed, and object contrast. There are also known interactions of these capture and display parameters with brightness and contrast, which are also generally linked in the display of imagery. For example, the Ferry-Porter law of psychophysics indicates the temporal frequency bandwidth of the visual system increases with increasing adapting luminance. We aimed to isolate the non-motion component, or judder, in a psychophysical study by using fundamental test signals, such as the Gabor signal. Two interval forced choice methodology was used to generate interval scales of judderness. Results will be presented for the viewer's assessment of the magnitude of judder, or judderness, as a function of these key parameters tested in isolation. Refs: 1.

- 16:30 A Quality Metric For High Dynamic Range
- The Peak Signal to Noise Ratio (PSNR) metric has long been utilized for codec evaluation and development, and other uses. However, for High Dynamic Range (HDR), the PSNR metric is not suitable. A more appropriate characterization of coding and image quality is to split image brightness into ranges (such as factors of two), and then determine the standard deviation within each such range. Once the standard deviation (sigma) has been determined, the two and three sigma population of pixel differences is shown as percentages of pixels. This is necessary because codec pixel differences do not typically follow a normal Gaussian error distribution. The value of sigma at each brightness range, together with the percentage proportions of two and three sigma outliers, provides an appropriate quality metric system for HDR.Presenter bio: Gary Demos is the recipient of the 2005 Gordon E.

- 16:00 IT-TV-Live - An Integrated Concept for IP-based Distributed Broadcast Production with 'SDI Quality'
- Broadcast production has been growing in complexity for several decades. This growth has been incremental, based on a largely unchanged broadcast architecture. Key components necessary for production-centric functions have evolved continuously in quality and functionality, but have brought increased complexity in signal routing and control interconnections. Today, signal routing is joining control in exploiting IP-based solutions; productions with widely-distributed acquisition and control locations must now be supported; new emerging control systems must be user-friendly; SDI-based studio quality must not be compromised in this transition. The paper describes a new, fully-scalable production-centric architecture, with software virtualization of a modular hardware device's network location. GPU-based on-demand video processing with compression-free interconnection via IP routing allows natural execution of creative intent in live productions. The linking network is scalable from studio to intercontinental access level. The enhanced functionality and flexibility now demanded in today's live productions is elegantly achieved in this major rethink.Presenter bio: In the grade of a 'Diplom-Ingenieur' in Electrical-Engineering from "Fachhochschule der Deutschen Bundespost" of Dieburg, he started his career 1982 in the QA-Department of “BTS” in Darmstadt. There, he adopted a detailed and widespread technical knowledge about all major Broadcast Studio Equipment. In 1989 he changed to the Software Development Department and migrated first into "KCM-125"-Camera- and finally into "DD30/35"-Switcher Software Development group. From very beginning he became part of the XtenDD/HD and subsequently KayakDD/HD Development team. The final 11 years while acquired by Thomson and Grass Valley, he headed this department as a Software Development Manager. Being within this 13 people core team they decided to follow their own global rethink about Broadcast Live Production by focusing on the future essentials while applying latest technologies. By supporting Scalable Video Systems (SVS) Development as a Program Manager, the revolutionary 'IT-TV-Live' concept is close to be released under "DYVI".
