- 10:45 The Pipe Dream Becomes Real: Advertising Workflows Come of Age
- The past year has been incredibly eventful in the development of advertising workflows. We can now embed a digital version of the advertising slate with delivered commercials, using the AMWA's AS-12. BXF can be used to exchange the schedule of commercials, instructions to move them from point A to B, and their metadata. It's also developing the ability to move copy rotation instructions from Agency to Broadcaster, filling the biggest gap existing today in the workflow. Ad-ID bridges all of this, making unique commercial identification simple. With an ever-expanding array of delivery platforms, as well as targeted advertising, maximum efficiency for advertising workflows has gone from a nice idea to a must-have. The good news is that we now have the tools to make it all work. We'll show how the whole thing fits together today, using industry standard approaches, taking the pipe dream of automated advertising workflows to reality.Presenter bio: Chris Lennon serves as President & CEO of MediAnswers.

- 11:45 Developments in the Realization of Practical File Based Workflow Environments
- Description: The imperative of file-based content environments has been compelling, but equally challenging. Media-based content environments have matured over virtually all of recorded history, and paradigms and tools have become so ingrained that their presence and utility have become second nature. To successfully make this transition tools are necessary to facilitate the workflows and other attributes of a true file-based infrastructure. LTO5, with its high density and throughput and its fundamental reliability, coupled with the Linear Tape File System (LTFS) are two such innovations. The fact that both technologies are well documented, standardized and multi-sourced is another essential component and leading indicator for positive contribution to file-based environments. This paper will discuss the business and technical necessities of moving to a file-based workflow, the history and attributes of LTO tape, the development and features of LTFS, and how all of these pieces can come together to create a modern environment.Presenter bio: David Pease has worked in the computer industry for more than 40 years.

Real-Time WorkflowsRoom: Salon 2
- 10:45 GPU-Based Real-Time 4K RAW Workflows
- Advances in digital imaging technology are fundamentally changing the cinema workflow and the tools artists and engineers traditionally use. Relatively inexpensive 4K resolution digital motion picture cameras capable of capturing and storing RAW sensor data with a wide dynamic range, high color gamut, and high bit depths all at frame rates that have traditionally been the domain of broadcast video are now available. Implementing a RAW workflow that provides real-time interactivity and a production path where all artistic choices are non-destructive requires a great deal of compute as every image displayed needs conversion from RAW sensor data to display oriented imagery and colorimetry. This highly parallel operation is well suited to the capabilities of modern graphics processing units (GPUs). This paper will present best practices for optimal GPU compute core and memory usage as well as efficient data transfer schemes for sensor data processing and display.Presenter bio: Tom is a Senior Applied Engineer for Media & Entertainment in NVIDIA's Professional Solutions Group where he focuses on the use of GPUs in broadcast, video and film applications ranging from pre-visualization to post production and live to air.

- 11:15 Dynamic Rate Control Technologies enabling Priority Based Bandwidth Allocation for IP News Gathering Networks
- In this paper, we propose an IP based news gathering network where terminals share bandwidth in accordance with the DiffServ model. Seamless route connection of IP networks and dynamic bandwidth allocation enables speedy and accurate coverage. Therefore, we developed two key technologies: a dynamic rate control for live video transmission and a modified TCP that considers transmission priority. This rate control adjusts each encoding rate of multiple videos that share a common path to avoid video interruption. The developed TCP allocates bandwidths at an appropriate utilization ratio with consideration of their priority while the conventional TCP allocates bandwidths equally among TCPs in the common path, and this protocol maintains backward compatibility with the conventional TCP. We evaluated these technologies by performing transmission experiments and proved that both live flows and file based flows can share network bandwidth appropriately by using the maximum bandwidth of the network.Presenter bio: Shuhei Oda has 7 years' experience in the broadcasting industry, starting with program production and system operation in 1999, before he moved into NHK Science and Technical Research Laboratories. He has been working in the area of video transmission systems for program production using IP networking technologies since 2006. His research interest covers traffic control and management of IP networks for the purpose of program production and exchange, and practical technologies dedicated to reliable and speedy program production.
- 11:45 Real Time File System for Content Distribution
- This presentation gives a deep view into the development of a file system, especially designed for scalable media files including JPEG 2000 and H.264 SVC. By applying specially developed techniques, including the Substitution Strategy, a real-time capable file-system can be built, even if the mass storage, or the interface to it, is too slow to deliver the data in the desired time. Rather than skipping whole files, new caching strategies will be shown that again, take advantage of the file-inherent scalability. The presented system also comprises an advanced user-rights-management that allows for granting access-rights to certain parts of a scalable file, rather than granting rights to whole files. Users will therefore get a different version of an image or video, dependent on their current access-rights. Due to the Media Repackaging Component, these customized versions will be generated on the fly, if a user requests it.Presenter bio: Heiko Sparenberg, born in 1977, received his Diploma degree in Computer Science in 2004 and a Master degree in 2006.

Performance Issues in File-Based WorkflowsRoom: Salon 1
- 14:15 Performance Parameters in File Based Workflows
- Establishing a high system performance value for rich-media file-based workflows is tightly coupled to storage bandwidth. Configuring small scale storage solutions can be straight forward and simple. However, larger enterprise class systems that intend to grow, that must bridge other media platforms and peripherals, and need to support multiple sets of clients and associated workflows require a proper storage solution with few limitations. The hidden issues that become performance killers in a large scale storage solution are frequently misunderstood. This paper will present some of those hidden parameters; provide examples on how systems can be designed for scalability in both capacity and bandwidth; and show that by proper planning and implementation the consequences of a poorly designed, under rated system can be alleviated.Presenter bio: As Chief Technologist at Diversified Systems, Karl Paulsen provides technology driven engineering services for projects related to media asset management, advanced digital video systems, workflow, and media storage technologies.

Prior to joining Cisco, Thomas spent ten years with various telecoms operators, including a FTTH triple play operator, for whom he developed their video architecture.
- 15:15 Being The Change You Wish To See: Changing Broadcast Schedules Right Up To Air
- The Internet has caused us to think about the words "dynamic" and "media" in new ways. Viewers now have access to whatever they want, whenever they want. Advertising is no exception. Advertisers expect the right ad to be shown to the right person, on the right device. This includes changing their minds about what they want to advertise, when, and where, right up to the time that the viewer sees the ad. Sounds like a nightmare, doesn't it? It used to be. Fortunately, we now have SMPTE's Broadcast Exchange Format (BXF), which is perfect for this task. We'll look at real-world cases in which BXF is enabling dynamically changing delivery of content, right up to the time the viewer sees it. So, don't fear change, embrace it. Oh, and you can expect to not only save money doing this, but also find new revenue.Presenter bio: Chris Lennon serves as President & CEO of MediAnswers. He is a veteran of over 25 years in the broadcasting business. He also serves as Standards Director for the Society of Motion Picture and Television Engineers.

Algorithms and CompressionRoom: Salon 2
- 14:15 HEVC - Enabling commercial opportunities through next generation compression technology
- High Efficiency Video Coding (HEVC) is near completion by the ITU-T | ISO/IEC Joint Collaborative Team on Video Coding (JCT-VC). The aim of HEVC is to revolutionize the compression world with a potential 50% bitrate saving over AVC, or H.264 / MPEG-4 AVC and even more dramatic bandwidth savings compared to MPEG-2. HEVC is already attracting much interest from acquisition to distribution and delivery to the home over all networks. Forecasts say 90% of IP traffic will be video by 2015, making HEVC an attractive enabler for new types of video consumption, from mobile devices served over unmanaged networks to high-end 4K TV to the home. This paper compares simulation results from the JCT-VC HEVC test model against an industry-leading AVC encoder. The paper also examines the behavior of selected HEVC tools that facilitate compression gains over AVC. Finally, it explores the significance of these efficiency gains for a variety of applications.Presenter bio: Lukasz has joined Ericsson Television in 2007 and has worked on various aspects of video processing and compression research.

- 14:45 Automatic Interlace or Progressive Video Discrimination
- Video content originates from a wide variety of sources. Even within one programme, several different video technologies may have been used during production. This paper discusses an algorithm that is able to reliably identify progressive and interlace frames. The algorithm is based on calculating a metric based on the degree of "interlacing artefacts" produced when adjacent fields from different frames are re-interleaved to reform a frame. The metrics are analysed over multiple frames to detect whether the material originates from a progressive or interlace source. This process has successfully been adapted to correct film-phase errors found in telecined archive material.Presenter bio: Manish Pindoria works as an Engineer at BBC Research and Development, currently focusing on digitisation and signal processing for archive applications.

Manish holds a masters degree in Engineering Science from Oxford University. He is the co-inventor of 6 patents.
- 15:15 Spatial Concealment for Damaged Images Using H.264/AVC Intra Prediction and Neighborhood Cliques
- Intra prediction methods introduced by H.264/AVC and furthered by HEVC, beyond enhancing intra coding efficiency also provide a potent tool for spatial error/loss concealment and digital film restoration e.g. scratches. In this paper, a novel H.264/AVC intra prediction based algorithm for spatial concealment is introduced. The proposed algorithm utilizes reliable intra prediction direction information from available neighboring regions in the same image (or video frame) and synthesizes intra prediction directions most suitable for erroneous/lost/damaged image regions. The synthesized intra prediction directions are used to conceal the underlying artifacts through pixel domain interpolation. Distinguishing features of the current work contributing to its success are its use of (a) an accuracy assessment and consequent weighting of available neighbors' information, and (b) conditional propagation of available neighbors' information based on the concept of 'neighborhood cliques'. Both features significantly improve the reliability of interpolation results. Proposed framework enables using both causal and non-causal information.Presenter bio: Seyfullah Halit Oguz received his B.Sc. (1987) and M.Sc.

The Unexpected in File-Based WorkflowsRoom: Salon 1
- 16:15 High-speed format converter with intelligent quality checker for file-based system
- NHK broadcasting is shifting to file-based systems for its TV production and playout systems including VTRs and editing machines. A variety of codecs and Material eXchange Format (MXF) formats have been adopted for broadcast equipment. These include MPEG-2/AVC and OP1a/OP-Atom. Video files need to be converted into the selected codec and format to operate efficiently. The quality of video and audio must be checked during this conversion process because degradation and noise may occur. This paper describes equipment that can quickly convert files to multiple formats as well as intelligently check the quality of video and audio during the conversion. The equipment automatically adjusts thresholds to detect errors in the quality check, depending on the type of codec and the spatial frequency of each area, which is divided into 16 sub-areas. Furthermore, this can be done in less time than the actual video length by optimizing the software processing performance.Presenter bio: Kenichiro Ichikawa received his B.S. degree from the Keio University in 2002 and M.S. degree from the Keio University in 2004.

- 16:45 Corralling the Chaos of Ancillary Data within Multiple File Formats
- SDI Based Workflows and formats were "iron clad" and well defined. These were the good old days when devices interconnected with ease thanks to the rigor and breadth of SMPTE Standards for SDI. Nowadays, with the great flexibility of File Based Media Workflows and the multitude of formats needed for different applications, we are dealing with incompatible wrappers and inconsistent or non-extendable ANC data carriage. This paper will look at these evolving workflows and the resulting Wild West of Files. More specifically the paper explores the challenges faced with the handling of ANC data such as AFD, captions, ad insertion triggers, Dolby's Dialnorm, etc., within various file formats. The paper then describes the unified and extensible approach offered by SMPTE436M for the carriage of ANC data within MXF wrapped files. Could SMPTE436M be the champion we need to restore order to the Wild West and corral some of the chaos?Presenter bio: Sara Kudrle is currently the Product Marketing Manager for Monitoring and Control within the Strategic Marketing group of Grass Valley, a Belden Brand.

Perception and the Human Visual SystemRoom: Salon 2
- 16:15 Quantitative Evaluation of Human Visual Perception for Multiple Screens and Multiple CODECs
- Great consumer experiences are created by a convergence of sight, sound, and story. This paper is an in-depth quantitative analysis of the neurobiology and optics of sight. More specifically, we examine how principals of vision science can be used to predict the bit rates and video quality needed to make video on everything from smartphones to Ultra HDTV a success. We present the psychophysical concepts of simple acuity, hyperacuity, and Snellen acuity to examine the visibility compression artifacts for MPEG2 and MPEG4/H.264. We also take a look at the newest emerging International compression standard HEVC. We investigate how the various sizes of the new compression Units (CU, PU, and TU) in HEVC would be imaged on the retina, and what that could mean in terms of the HEVC video quality and bit rates we would likely need to deliver quality content to smartphones, tablets, HDTV, 4K TV, and Ultra HDTV.
- 16:45 Perceptual Signal Coding for More Efficient Usage of Bit Codes
- As the performance of electronic display systems continues to increase, the limitations of current signal coding methods become more and more apparent. With bit depth limitations set by industry standard interfaces, a more efficient coding system is desired to allow image quality to increase without requiring expansion of legacy infrastructure bandwidth. A good approach to this problem is to let the human visual system determine the quantization curve used to encode video signals. In this way optimal efficiency is maintained across the luminance range of interest, and the visibility of quantization artifacts is kept to a uniformly small level.Presenter bio: Scott Miller is a senior member of the technical staff at Dolby Laboratories where he serves in the Imagaging Research group. He specializes in image display technology and video signal processing, most recently working on Dolby's Professional Reference Monitor. He received a B.S. in electrical engineering from Cornell University and has spent nearly 30 years working in the video industry, including several years with Panasonic Research where he helped develop the Emmy award winning Universal Video Format Converter.
- 17:15 Human Perception & Advancements in File-Based Quality Control
- When retrieving video pictures from digital video tape or film prints, artifacts are generally introduced via methods that are difficult to detect without use of the human visual system, since many of these artifacts do not have a common, mathematically definable pattern to them. These artifacts can include film tearing, film dirt, analog noise, block-based digital drop outs and others. This paper covers a newly designed metric and the implementation methods used to automatically find these types of artifacts without need of an external reference, substantially functioning and locating artifacts in the same method as the human visual system. The paper also shows the viability of this metric in a system, and how this metric is useful and cost-saving for file-based content preparers compared to existing, manual processes for content review.Presenter bio: Eric Carson has been listening to customers & building innovative products to meet their needs in the digital media test & measurement space for over 10 years.

- 09:00 Leveraging Fiber Properties to Our Advantage
- A strand of optical fiber is inherently thin, flexible, and light weight. How can we leverage these properties to improve the fiber installation process and make it easier to adapt to changing facility needs? A new infrastructure / installation technology called "Air Blown Fiber Infrastructure" facilitates this approach. Using a point-to-point network of high density tubes as a highway, 3000 ft. of 24 strand- fiber can be blown (installed) from source to destination across a facility in just 30 minutes. Once the tube network is in place, changes can be made at a fraction of the time and cost of conventional fiber networks, without disruption to the network or the facility. Technical Discussions include: • What ABF looks like and the science • Design Considerations (intra-building, campus) • Tube Bundle Specifications and Limitations • Fiber Bundle Installation Considerations and Options • Jetting Specifications, Limitations and Testing • Termination OptionsPresenter bio: John brings a wealth of knowledge to Fiber Core Networks as Director of Operations.

- 09:30 Trends in wireless high-bandwidth display technology
- The newest generation of high-resolution digital display interfaces now has a new face: Wireless connectivity. Several systems, including generic WiFi (802.11)-based products, have already come to market. Two of them - 6 GHz wireless high-definition interface (WHDI) and 60 GHz wireless HD (WiHD) - are competing head to head in the consumer electronics space, while a wide-channel, short range implementation (ultra wideband, or UWB) is also making headway. All of these systems support full bandwidth HDMI and DisplayPort signals (10 Gb/s) with low latency, making them attractive as well for 3G camera-to-monitor links for field video production. This paper will describe each system and explain their advantages and disadvantages, as well as the differences between them.

- 10:00 Next-generation techniques for the protection and security of IP transport
- Few in the professional video community foresaw IP's rapid ascent to its position as a, if not the, dominant video transport protocol. To many, IP lacks the control and protection so critical to video networking. While today's IP network infrastructure, driven by the speed and capacity requirements of data centers and cloud-based services, is now capable of carrying professional video in a controlled, usable manner, significant concerns remain for the best way to control, monitor and protect services in wide area routed networks. This paper will focus on recently-developed techniques for real-time data flow protection now undergoing trials and initial deployment, including: delay offset launch network stream feeding for dual-path protection (enabling simultaneous network hits on dual-path connectivity); single path protection using control techniques for dynamic end-to-end movement of data buffering (bandwidth savings and effective dual-path protection); and RTP source coherence across multiple sources for seamless source and destination protection.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.

- 09:00 Unconstrained 2D to Stereoscopic 3D Image and Video Conversion using Semi-Automatic Energy Minimization Techniques
- We present a method for semi-automatically converting unconstrained 2D images and videos into stereoscopic 3D. User-defined strokes for the image, or over several keyframes, corresponding to a rough estimate of the scene depths are defined. After, the rest of the depths are solved, producing depth maps to create stereoscopic 3D content. For video, to minimize effort, only the first frame has labels, and are propagated over all frames by a robust tracking algorithm. Our work combines the merits of two energy minimization techniques: Graph Cuts and Random Walks. Current efforts rely on automatic or manual conversion by rotoscopers. The former prohibits user intervention, or error correction, while the latter is time consuming and prohibits use in smaller studios. Semi-automatic is a compromise to allow more faster and accurate conversion, decreasing the time for studios to release 3D content. Results demonstrate good quality stereoscopic images and video creation with minimal effort.Presenter bio: Raymond Phan is a Ph.D. candidate with the Department of Electrical and Computer Engineering at Ryerson University in Toronto, Ontario, Canada.

- 09:30 Image Enhancement Using Similarity-based Color Matching for High-quality Stereoscopic 3D Image Acquisition
- Stereoscopic three-dimensional (S3D) movies often suffer from the inconsistency problem between left and right images acquired by a stereo camera due to unstable filming environment. This research introduces a novel image enhancement algorithm using similarity-based color matching of S3D images. The proposed algorithm first partitions both reference and target images into multiple sub-blocks, and decomposes them into reflection and illumination components using retinex theory. Color correction is performed by matching histograms of a corresponding pair of blocks based on the structural similarity index measure (SSIM). The color corrected images are finally enhanced by removing noise using a priori trained dictionary-based patches. We can make high-quality S3D images from imperfect input images acquired under critical conditions including limited dynamic range, unstable calibration of stereo camera pairs, and low signal-to-noise ratio (SNR). The proposed method can be applied to high-quality panorama images, frame difference-based video tracking, and similarity-based image analysis.Presenter bio: Wonseok Kang was born in Jeju, Korea in 1983.

- 11:00 High Performance Optics for a New 70mm Digital Cine Format
- This paper details technical features of the first series of high-speed prime lenses specifically designed for a new 70mm digital cine format. These new lenses offer full aperture (f/2.5) performance at or near the diffraction limit from near-UV to near-IR over a 48mm x 20.25mm image area. Additionally, these lenses are designed to work properly with optical filters inserted between the lens and sensor. Twelve focal lengths are under development, ranging from a 27mm ultra-wide to a 300mm telephoto. In addition to traditional externally geared controls, all lenses have internal motors for focus and aperture. High-resolution metadata is continuously transmitted to the camera, including focus distance, aperture, temperature, and individual lens identification. A replaceable internal filter near the aperture stop permits a wide range of creative effects, including soft-focus.Presenter bio: Dr. Caldwell has been a professional lens designer since 1985, and has completed more than 500 design projects.

- 11:30 Focusing on lens metadata
- Motion pictures are increasingly created from a combination of real and virtual subjects. This involves the creation of a "virtual" camera that must closely emulate the camera behavior during principal photography. Use of highly dynamic camera moves during a shot have made it nearly impossible to deduce from the images and written notes the lens settings and characteristics. It is now both possible and necessary to record on a frame-by-frame basis the status of the taking lens. Modern post-production workflow, especially for stereoscopic 3D, increasingly demands an accurate record of the lens settings to facilitate compositing. This paper will discuss the following: - the objectives and advantages of having these data - the current state of the art of lens metadata in the industry - techniques for acquiring, preserving, disseminating and using these data - whether a standard or RP is desirable and achievablePresenter bio: From his student filmmaker days in London through industrial design work to his founding role in industry technical organizations, Visual Effects Society Fellow, Jonathan Erland has been engaged in both the dramatic and technical side of the story-telling process for over 50 years.

- 12:00 Computational photography for dust and scratch detection on transparent photographic material
- This work pertains the digital restoration of motion-picture films. A new method for the automatic detection of blemishes on any kind of transparent photographic material (still and moving images, silver-based and dye-based material) is presented. It consists in an innovative combination of different illumination techniques and computational photography. The image layer is a random dispersion of microscopic elements (e.g. silver particles in b&w material) and its interaction with light is isotropic. Dust, scratches and other irregularities of the film surface produce shadows and reflections that are strongly dependent on the provenance of light. The acquisition of multiple images with different geometries of illumination, and the analysis of the differences between them, is found to be an effective method to emphasize irregularities in the film surface. Moreover, cross-polarization technique is found to improve the blemish detection. We present the description of the experiments that determined the method in its details.Presenter bio: I received my BSc degree in Technologies for Conservation and Restoration of Cultural Heritage in 2004 and my MSc degree in Science for Cultural Heritage in 2009, both from the University of Florence.

- 14:15 Towards Higher Dimensionality in Cinema Color: Multispectral Video Systems
- The digital transition being experienced by the motion picture industry has afforded an increase in dimensionality in time and space, however, comparatively little effort has been put into expanding color. All practical motion imaging systems continue to rely on metamerism, wherein a 3-channel signal is sufficient to reproduce the color of real objects regardless of higher order spectral composition. Such treatments restrict cinema color, offering limitations in absolute color accuracy and gamut and exacerbating observer metamerism. Multiprimary reproduction focused on spectral accuracy or metamerism reduction may prove a better answer to enhancing the color experience. It also promises to open new color management paradigms for visual effects compositing of live action and CGI or for virtual cinematography. The proposed talk summarizes past and present research in multispectral video. Preliminary results from the design and construction of an abridged multispectral video capture and display system will also be presented.Presenter bio: David Long joined the faculty of the School of Film and Animation at Rochester Institute of Technology in 2007, where he is currently Program Chair and Associate Professor for the BS Motion Picture Science program.

- 14:45 Issues in Color Matching
- To create a numerical description of color (e.g., X,Y,Z), one applies a Color Matching Function to spectral power distribution data acquired with an instrument such as a spectroradiometer. All the adjustments one makes to a video display or to video data depend on the accuracy of these numbers. Since 1931, the broadcast industry and others for whom color fidelity is crucial have depended on the 1931 CIE Color Matching Function (CMF). Recent (and continuing) advances in display technology, however, have exposed serious deficiencies in this CMF. These deficiencies have long been known to academic researchers, who have in the intervening years proposed several alternative CMFs. This paper reviews the critical flaws that render the 1931 CMF no longer reliable, and surveys the strengths and weaknesses of candidates for its replacement.Presenter bio: As a veteran of the software industry, Joel spent the first several years working at a graphic design studio managing color critical work stations. He then began writing his own software to calibrate PCs and home theater computers, and was then hired away to SpectraCal. In his current position as SpectraCal's Director of Software Development, he has presided over the development of one of the most sophisticated color management packages available. The research he's done developing this engine makes him uniquely suited to discussing color matching functions and their role in video calibration.
- 15:15 Accurate ACES Rendering in Systems Using Small 3DLUTs
- The ACES color space has unlimited dynamic range, however, it is difficult to implement ACES workflow with the grading systems currently in use. To this end, we propose custom Log ACES and High Saturated Log ACES methods. The custom Log ACES can process negative ACES values and can handle high dynamic range. HSLA expands the ACES color space to reduce vacant area and spread real color data area in order to use 3D LUTs more effectively. These two methods drastically improve accuracy of color reproduction even if the post-production system only supports a highly limited dimension or very small number of lattice points for its 3D LUTs.Presenter bio: After graduating from Tokyo Institute of Technology, Mitsuhiro Uchida entered Fujifilm and started research and development of color photographic film.

- 16:15 The Unfolding Merger of Television and Movie Technology
- HDTV utilizes "in-camera" or "in-switcher" rendering for live broadcast, wherein the interpretation of the scene for display happens immediately. Typical rendering is typically modeled upon an in-camera matrix and gamma boost, and a highlight "knee". Such shows are usually captured, processed, transmitted, and displayed at 50 or 60 fields or frames/sec. Telecine mastering of shows interprets and renders the scenes from a film negative, but not in real time. The rendering of colors during telecine is often more of a print film emulation than a video-style process. Such shows are usually mastered at 24 frames per second, and may be shows made for television, or cinematic movies being presented on television. The industry move from film-based capture to digital camera capture has begun to bridge the gap between the television image model and the telecine film-input model. The key new ingredient bridging this gap is the Reference Rendering Transform.Presenter bio: Gary Demos is the recipient of the 2005 Gordon E.

- 16:45 Theatrical versioning in the content pipe - integrating digital cinema into end to end workflow
- Digital cinema compression, versioning and packaging is traditionally a cul-de-sac process within the life of a movie as content flowing through the "pipe" to different versions and delivery formats. With more integrated workflow and appropriate mezzanine files, the creation of digital cinema packages can become part of the flow of content from the creation to all downstream deliveries. Looking processes, system architecture and technology choice to show how this allows us to efficiently flow content from capture/creation to the final consumption point, be it the cinema, TV, tablet or mobile. Building work flows now that are extensible to the many coming new formats such as high frame rate, object oriented audio, wide colour gamut etc.Presenter bio: In his role as Head of Operations for Digital Cinema at Technicolor, Richard is responsible for mastering, distribution, and client services for theatrical releases.

- 17:15 Low-latency transmissions for remote collaboration in post-production
- The post-production often involves several key parties who want to be in the control of the process - the director, the producer, the editor, and several technical experts - the colorist, the stereographer, the sound master, etc. Some decisions are more effectively done in real-time, interactively. However, the participants are often very busy, working on multiple projects in parallel and it is difficult for them to travel together for a collaborative session. We believe that future technology for low-latency high-quality transmissions of image and sound will enable remote real-time collaboration in post-production. As the capacity of optical networks is increasing, uncompressed transmissions of original content with minimal latency will be possible. We did several experiments with real-time remote collaboration in color grading and stereography to over 10000 km between Europe and West Coast US, using GLIF (Global Lambda Interchange Facility) network. We describe the key technology aspects and lessons learned.

- 16:15 The Cloud - What does it mean for media archives?
- 16:45 Cloud Media Collaboration, Enter Stage Right: and Action
- As digital media files grow in size and complexity, media service providers spend more time and resources than ever before developing, transferring, storing and optimizing them. With disks still being flown across the world between various partners involved in productions, the industry clearly needs a more efficient, pragmatic solution for collaboration and service delivery. It's time the media industry stepped into the future with the cloud. Public clouds offer collaborative ecosystems in which providers can essentially work together "under one roof" to improve the efficiency of their services, including file conversion, media injest, file transfer acceleration, encoding/transcoding, long term object storage and content delivery. This presentation provides a technical overview of how public cloud ecosystems offer a media hub with high connectivity and cost effective access to computing resources. Compelling case studies will provide practical guidance for attendees hoping to move media operations (compute, applications, storage, etc.) to the cloud.Presenter bio: Robert Jenkins is the co-founder and CEO of CloudSigma and is responsible for leading the technological innovation of the company's pure-cloud IaaS offering.

- 17:15 Delivering live multi-cam content to smart devices through cloud platforms
- Broadcasters must engage a new generation of multitasking viewers who no longer sit passively in front of their televisions but browse the internet and interact with social media while watching TV. Rather than risk losing viewers, broadcasters can provide original premium content — including unseen camera angles and highlights — to viewers via second screens. The large amount of unused content that sits on live TV production servers can be used to enrich the user experience and maximize the value of content. This paper will explore technology challenges in building open and scalable platforms to deliver high quality experiences on second screens, including: - Best practices in building near-live multi-camera replay platforms on top of standard live production environments - Overcoming challenges in cloud-based production and delivery to multi-screens - Integration with social networks, archives, stats and other third-party contentPresenter bio: Werner Ramaekers has worked in software engineering for the past 20 years.

- 09:00 Towards using Audio for Matching Transcoded Content
- With the advent of multiple screens for viewing, transcoding and transformation of content is becoming a mainstay of content delivery systsems. But Transcoding implies that copies and versions of the same content can proliferate across various storage devices. It also means keeping track of content becomes a major problem both from copyright and recording/indexing perspectives. In this context, video-based copy detection has emerged as a major area of research. On the other hand, audio-based techniques have received much less focus but audio could provide very useful supporting copy detection cues. In this paper, we present a systematic investigation of how audio signatures undergo transformation under typical transcoding operations including bitrate changes, codec transformation, sample rate variation, and standard audio transforms like downmixing/volume normalization.Presenter bio: Dinkar Bhat received the B.Tech. degree in electrical engineering from the Indian Institute of Technology at Madras (now Chennai), the M.S. degree in computer science from the University of Iowa, Iowa City, and the Ph.D. degree in computer science from Columbia University, New York.

- 09:30 Using Name Spotting in Audio/Video Media Identification to Improve Media Discovery Service in Digital Object Architecture
- Digital object repository, a component of digital object architecture, stores large number of audio/video files (as digital objects) and provides access and retrieval to them. Sometimes metadata for audio/video files are almost absent. Lack of enough metadata limits media discovery service from fetching the files containing little metadata. In addition, the media discovery service excludes those files from the result set. Relevant information, such as names, can be extracted from the given content of an audio/video file and appended in metadata of the same audio/video file for enhancing the media discovery service. In this research, we use a Hidden Markov Model and Viterbi algorithm based name spotting module, known as IdentiFinder to extract names. The research will help to make large number of audio/video files visible to the media discovery service with the help of name extraction. Also, it will increase the user satisfaction by improving the search result set.Presenter bio: Manish Goswami came to USA to pursue MS in CS at California State Polytechnic University, Pomona in September 2010.

- 10:00 Practical Quality Assessment for Digitized Film Content
- The CineXPRES project introduces a practical quality assessment framework for digitized film, based on theoretical approach previously presented by one of the author at the SMPTE 2010 Fall Conference. A bottom-up workflow provides subjective quality reference from audience ratings of selected training contents shown on given displays. It also computes a permanent objective quality measure from degradation models and visual perception models. Bayesian network inference provides a "conditional subjective quality estimation" that depends on a given display. The same inference mechanism computes a "conditional objective quality estimation" through an expected cost function, by taking into account current image processing technologies and contextual information. Bayesian networks are powerful tools integrating expert knowledge and able to evolve with new information. These quality estimations must serve three purposes for long-term preservation: evaluation of the restoration work, comparison of similar contents before preservation and computation of a permanent content quality reference.Presenter bio: Short Bio for Francois Helt Background in Mathematics and Film making, 28 years experience in Professional Video and Film, Designing Image Processing software since 1981, R&D manager of teams dedicated to special effects software including film scanners and film printers drivers since 1991.

- 09:30 Effects of viewing conditions on fatigue caused by watching 3DTV
- In order to enjoy a pleasant experience watching 3DTV, it is necessary to collect and analyze reliable safety assessment data. Evaluation experiments were conducted consisting of 500 adult participants watching 3D content for approximately one hour on commercially available 46 to 50-inch 3DTVs that require the use of shutter glasses. The degree of fatigue after watching the 3DTV was evaluated under various viewing conditions based on objective and subjective indexes of fatigue. The results of objective indexes showed that there was no statistical difference between watching 3DTV and traditional TV (i.e., watching 2D content without glasses) in degree of decline of visual and cognitive functions due to fatigue. On the other hand, the results of subjective indexes indicated that there were some differences between watching 3DTV and traditional TV in the sensation of fatigue, which may not be attributed to watching 3D content, but to wearing the 3D shutter glasses.Presenter bio: Toshiya Morita received a diploma in college of information sciences in 1984 from University of Tsukuba, Ibaragi, Japan.

- 10:00 High Performance Polarization-Based-3D and 2D Presentation
- Systems for delivering 3D content in digital cinemas are inherently lossy. In the absence of careful attention to design, component efficiencies, and maintenance, the result can be an image luminance below 4.5 fL, even on modest sized screens. In addition, aspects of a 3D system can determine the performance of 2D presentation. Given the large installed base, methods for increasing brightness and image quality are sought which leverage existing projector platforms. This paper evaluates loss mechanisms in 3D projection systems and shows that high-brightness 3D is feasible using lamp-based illumination. These solutions can be implemented using single-projector sequential 3D, for conventional sized screens (averaging 40'), as well as premium large format screens in excess of 60'.Presenter bio: Dr. Gary Sharp joined RealD as Chief Technology Officer in 2007 after RealD acquired ColorLink.

- 11:30 Development Of A 70mm, 25megapixel Electronic Cinematography Camera With Integrated Flash Recorder
- This paper will describe the system design of the world's first 70mm, 25 megapixel, electronic-cinematography camera with an integrated flash memory recorder. Prior to 2004 the only so called "4K" imaging systems consisted of a single line array of 4096 photo-sites or in some instances three 4096 line arrays. A color "4K" scan of an Academy 35mm cine frame would generate a digital image that would be the equivalent of a 29 megapixel area array camera sensor. In 2004, one camera manufacturer introduced a 4096 x 2048 pixel CCD camera for cinema applications and declared it was a "4K" camera. Soon many would follow, and today this particular piece of obfuscation is rampant in the motion picture industry. Despite all the technical challenges in creating the first "True 4K" large format digital cinema camera one of the greatest challenges we are faced with is how to end the "4K" confusion.Presenter bio: B.

- 12:00 1080p50/60, 4K and beyond: Future Proofing the Core Infrastructure to Manage the Bandwidth Explosion
- Traditional broadcast infrastructures only had to support one version each of SDTV and HDTV, plus extensions such as RGB 4:4:4 for better chroma keys. Now we need to support 4:4:4:4 for external keys, high dynamic range (HDR) imaging, stereoscopic 3D, a 3D disparity channel, Quad-Full HD, higher frame rates etc, all of which drive real time streaming media bandwidth requirements. How do we accommodate these new demands and stay future proof within our core broadcast infrastructure? This paper outlines the latest developments, at the technical and standardization levels, to handle the emergence of new production formats. It examines changes to the studio infrastructure which add the flexibility needed to accommodate new production formats alongside existing formats, with maximum compatibility and minimum confusion. It then suggests methods to greatly increase the observability of studio networks, and improve functionality and compatibility at the control and monitoring plane.Presenter bio: John Hudson is Director of Product Definition and Broadcast Technology in the Gennum Products Group of Semtech Corporation.

- 11:30 A study of the optical distribution costs of multichannel baseband digital broadcasts over a FTTH network
- We have previously proposed a baseband time-division multiplexing method for the transmission of digital broadcasts over FTTH. Here, we evaluate the transmission equipment cost of the proposed method based on a simple assumed distribution network. We predict that the cost can be decreased to 11-36 % of that of conventional sub-carrier multiplexing (SCM) and FM conversion transmission methods. By analysing the dominant factors affecting the cost, we show that significant savings are achieved due to the fact that an optical signal can be received at a lower power using the proposed method than for signals transmitted using conventional methods.Presenter bio: Takeshi Kusakabe received the B.E. and M.E. degrees in science and engineering from Waseda University, Tokyo, Japan, in 1999, and 2001, respectively.

- 15:00 Systemization of Network-Based Genlock
- Traditional synchronization systems based on blackburst, tri-level sync, DARS and timecode have little relevance in the networked world, and today represent a cumbersome and dated infrastructure overhead. These legacy systems, while continuing to provide utility, do not map into the future systems which are evolving today. SMPTE is working on a universal method for delivering any reference to a virtually unlimited number of devices over an IP network. This technology spans everything from simple configurations of a few pieces of gear to campuses, regional and global networks. This paper will investigate the opportunity for system designers to migrate to this new infrastructure, discussing the core network technology on which it is based, as well as system-level deployment considerations. In addition to replacement of existing synchronization architectures, it will explore new opportunities not possible using legacy methods.Presenter bio: Paul Briscoe Bio Paul began his career in the broadcasting industry in 1980 at the CBC in Toronto.

- 14:30 Further investigations into the interactions between cinema loudspeakers and screens
- Modern day data acquisition techniques allow the gathering of high resolution polar data to assess the performance of loudspeakers. While these techniques have become common in laboratory and engineering environments during product development, these same techniques can be applied to aspects of exploration beyond initial product development which affect the in-situ performance of loudspeakers. This paper will use modern high-resolution data acquisition techniques and analysis tools to investigate the complexity of the interactions between loudspeakers in typical locations behind the screen in a typical cinema presentation environment. Discussion will explore the impact on the loudspeaker responses of various types of screen surfaces and the distance between the screen and the loudspeakers. The measured performances will be compared to the standards for system response set out in ST-202 and the impact on patron listening experience will be assessed."Presenter bio: With over 15 years in professional audio Long has a diverse and extensive knowledge regarding the design and implementation of sound reinforcement and playback systems for all types of installations ranging from simple single speaker events to massive show spectaculars and multi-channel media presentation environments.

- 15:00 Frequency Response Versus Time-of-Arrival for Typical Cinemas
- Cinema equalization is typically based on the use of 1/3-octave, minimum phase filtering to adjust the spatial average of the steady-state magnitude response from multiple microphones to the X-curve. This paper explores one aspect of this process, namely whether the use of steady-state response is appropriate. To do this, the relationship between early-arrival and steady state spectral characteristics for typical cinemas was examined. The comparison between early-arrival and steady-state sounds was done via spectral analyses of impulse responses measured at multiple microphone locations within the audience seating area. The cinemas surveyed varied in size between 30 - 1500 seats and the time gating intervals varied from 4 ms to that equivalent to steady state. When this was done, front loudspeaker measurements showed little spectral tilt upward toward "brightness" for early arrival, compared to steady-state sounds, and a modest upward tilt for surround loudspeaker arrays in the largest cinemas.Presenter bio: Louis Fielder received a BS. degree in electrical engineering from the Caltech in 1974 and an MS. degree in acoustics from the UCLA in 1976.

- 16:00 Broadcasting video over the Cellular network and the Internet
- Huge chunks of the off-air broadcast and microwave television spectrum have slowly and systematically been lopped off in deference to the burgeoning demand and unquenchable thirst for Broadband Services. The first wave came with the DTV conversion and then again with the 2 GHz ENG BAS analog to digital spectrum reduction. All the while, the volume of news gathering content and distribution has dramatically increased to keep pace with the public's insatiable hunger for these ever evolving media rich services. So how can the broadcaster function in the midst of this escalating and diametrically opposed broadcast environment? The answer is through increased efficiencies in modulation and encoding techniques and leveraged augmentation of 3G/4G wireless infrastructures. This paper explores the new use of bandwidth-reducing modulation techniques and the shift from the use of MPEG-2 to MPEG-4 (H.264) video encoding, thereby creating higher value propositions for this encroached upon television broadcast spectrum.Presenter bio: Nuraj Lal Pradhan is a Wireless Network Engineer at Vislink, Inc.

- 16:30 Multiformat Operation - System Implications and Solutions for Routing Switchers
- This paper discusses the formats and media involved when routing simultaneous, multiple video and audio formats, on a variety of physical interconnections, the implications of operating in such an environment, proposes possible operational practices, and reviews practical solutions available. The simultaneous use of multiple video and audio formats, on a variety of physical interconnections, coupled with the demand for increased efficiency, has created new challenges for today's systems engineers and planners when specifying a routing switcher. Transitioning to various high-definition video formats and increasingly dense audio formats has increased the overall complexity of these multi-format systems—a 36,864 x 36,864 embedded audio matrix for an 1152 x 1152 video router! Simultaneously, audio and video processing requirements should be accommodated. Internal processing enables system and operational efficiencies: Control is simplified; a flexible input/output arrangement allows easy reconfiguration between uses. Finally, a glimpse into the future - will it get easier?Presenter bio: Currently Senior Product Manager for Snell Limited UK responsible for Advanced Routing and Processing Systems.

- 17:00 Here Comes Ethernet
- Ethernet has been around since 1973, and you're probably aware of many companies who have struggled to make it work for audio and video applications. But those are proprietary systems where often Box A can't talk to Box B. So IEEE, which owns the Ethernet standard has been working on a re-write of the Ethernet standard called 802.1BA AVB, and the AVB is for audio and video bridging. Finally, this standard may herald a new way to design, install and operate audio and video facilities.Presenter bio: Steve Lampen has worked for Belden for twenty-one years and is currently Multimedia Technology Manager and also Product Line Manager for Entertainment Products.

- 16:00 Tutorial on Critical Listening of Multi-channel Audio Codec Performance
- Listening for impairments introduced by multichannel audio codecs is an important task. Classical objective methods are not adequate in assessing audio coding schemes. Accordingly, the ITU-R BS.1116 & 1534 recommendations provide guidelines for subjective evaluation of codecs. This paper provides a tutorial on the proper conditions to do reliable codec testing. Several key components covered are, proper experimental design, selection of listening panel and training of listeners, developing the test methodology, selecting balanced program material, loudspeaker/room and sound-field requirements, listening for artifacts, and statistical analysis. This paper addresses these various components including the sound-field requirements since, as per the ITU: "The characteristics of the reference sound field at the listening area are most important for the subjective perception of, or the quality assessment of, auditory events and their reproducibility at other listening places or rooms. These characteristics result from the interaction of the loudspeaker(s) and the listening room".Presenter bio: Sunil Bharitkar, received his Ph.D. in Electrical Engineering from the University of Southern California (USC) in 2004.

- 16:30 Scalable Format and Tools to extend the possibilities of Cinema Audio
- Surround sound has been making cinematic story telling more compelling and immersive for over 30 years. The first widely deployed surround systems used magnetic recording. Later, optical recording became standard, enabling up to 7.1 channels of audio. With the transition from film to digital distribution there is an opportunity for the next generational step forward. In this paper we describe a new surround sound format that dramatically advances the capabilities of cinema sound. The format was developed in close cooperation with industry stakeholders and was specifically designed to provide the most desired new capabilities and provide a path for future enhancements, while respecting and leveraging the strengths and know-how of the current sound format and pipeline. In particular, the new system maintains and advances the ability to deliver impeccable audio quality, and flexibly extends the creative possibilities to meet the needs and aspirations of both content creators and exhibitors.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.

- 17:00 Lee de Forest and the Invention of Sound Movies, 1918-1926
- Lee de Forest received his Ph.D. in physics from Yale in 1899 and entered the 20th Century as an inventor. By 1906 he had patented his signature invention, the three-element vacuum tube he called the "Audion." Beginning in 1918 he improved upon the earlier work of Bell and Ruhmer and patented a system of writing sound on motion picture film for synchronized talking pictures. Between 1920 and 1926 he worked with fellow inventor Theodore Case to develop the Phonofilm system of variable density recording. De Forest presented his work to the SMPE on four occasions between 1923 and 1926. Even though the de Forest system would not end up the preferred one for sound, his tube would be the key as it allowed amplification of audio using loudspeakers which made it possible for audiences to experience talking pictures. In 1960 de Forest received an Oscar for his sound-on-film contributions.Presenter bio: Mike Adams has been a radio personality and a film maker.
