Digital Television in Brazil
The choice of the Japanese system of terrestrial digital television as the basis of the Brazilian system was made in June 2006. In December of the following year, the first commercial digital transmissions began, with the full integration of the most powerful tools for source coding and thorough adaptation of the multiplexing and transmission layers to meet the country's specificities. Interactivity is now beginning, based upon a uniquely flexible and royalty free interactive framework. This talk will give an overview of the extensive work that has been performed through the joint effort of broadcasters, equipment industries, software companies, research centers and universities to create and launch a state-of-the-art system, which allows free-to-air television broadcasters in Brazil to offer high definition video, multichannel audio, robust reception for both fixed and handheld/mobile uses and flexible interactive applications, and is equipped with tools which leave room for extensive further development. Liliana Nakonechnyj is the president of the Brazilian Society of Television Engineering (SET) and the director of Transmission Technology and Engineering Support for the Globo TV Network. Liliana graduated as a telecommunications engineer from the Catholic University of Rio de Janeiro, and holds two MBAs degrees in business and strategic management. Her career has been mostly dedicated to launching innovative transmission systems, taking advantage of satellite, terrestrial, and fiber optic technologies. Since 1994, she has lead studies for the introduction of terrestrial digital television in Brazil and is currently working on its implementation within both the Globo Television Network and the Brazilian Forum of Digital Television.

3D Data Formats, Delivery & Display Technologies Delivering higher resolution video and providing an immersive multimedia experience in the home has been a primary target for industry and researchers in recent years. It has finally become possible to offer a compelling 3D video experience on consumer electronics platforms. In addition to this, there has also been a notable increase in the production of 3D contents. This talk will review the various representation and coding formats for stereo and multiview video that are available or actively being developed for next-generation 3D video services. Several distribution scenarios will be discussed including packaged media such as Blu-ray Disc, gaming, as well as the premium content delivery over cable, terrestrial and Internet channels. The unique challenges and requirements for each environment will be analyzed. Several types of 3D displays will also be described and the data requirements for each examined. The talk will conclude with a discussion of future outlooks and existing research challenges. Anthony Vetro received the B.S., M.S. and Ph.D. degrees in Electrical Engineering from Polytechnic University, Brooklyn, NY. He joined Mitsubishi Electric Research Labs, Cambridge, MA, in 1996, where he is currently a Group Manager with responsibility for research and development in the area of multimedia and information coding, and has published more than 130 papers on video coding, display processing, biometric security and multimedia adaptation. He has also been an active member of the MPEG and JVT standardization committees for many years, where he has served as ad-hoc group chair for various activities and as an editor for several specifications, including the multiview video coding amendment of the H.264/AVC standard. He also serves as Vice-Chair of the US delegation to MPEG. Dr. Vetro is also active in a number of IEEE conferences, technical committees and editorial boards. He is currently Chair of the Technical Committee on Multimedia Signal Processing of the IEEE Signal Processing Society, and serves on the steering committees for ICME and IEEE Transactions on Multimedia, as well as the Editorial Board of IEEE Signal Processing Magazine. He served as an Associate Editor for IEEE Signal Processing Magazine (2006-2007), Conference Chair for ICCE 2006, Tutorials Chair for ICME 2006, and on the Publications Committee of the IEEE Transactions on Consumer Electronics (2002-2008). He is a member of the Technical Committees on Visual Signal Processing & Communications and Multimedia Systems & Applications of the IEEE Circuits and Systems Society. Dr. Vetro has also received several awards for his work on transcoding, including the 2003 IEEE Circuits and Systems CSVT Transactions Best Paper Award. He is a Senior Member of the IEEE. | |  Vivek Goyal, Massachusetts Institute of Technology
Compressed Sensing: Revisiting Resolution, Modeling, and Computation Resolution of a data acquisition system is usually thought to be determined completely by sensing properties, such as density and accuracy of measurements. Compressed sensing prompts a reconsideration of the concept of resolution. This talk advocates the view that resolution is, in addition, dependent on signal modeling and the complexity of computations allowed in interpreting the measurements. This view is developed concretely for the acquisition of sparse signals, where the asymptotic relationship between resolution and the number of measurements is studied for algorithms with various complexities. Estimation based on convex optimization or greedy algorithms has been emphasized in the compressed sensing literature. These methods are reviewed and put into context by comparing against information-theoretic bounds and a computationally-trivial approach. The talk is based on joint work with Alyson Fletcher and Sundeep Rangan. Vivek K Goyal received the B.S. degree in mathematics and the B.S.E. degree in electrical engineering from the University of Iowa and the M.S. and Ph.D. degrees in electrical engineering from the University of California, Berkeley. He was a Member of Technical Staff in the Mathematics of Communications Research Department of Bell Laboratories, Lucent Technologies and a Senior Research Engineer for Digital Fountain, Inc. He is currently Esther and Harold E. Edgerton Associate Professor of Electrical Engineering at the Massachusetts Institute of Technology. His group's work can be found at http://www.rle.mit.edu/stir/. Dr. Goyal received the Eliahu Jury Award of the University of California, Berkeley, for his thesis research, the 2002 IEEE Signal Processing Society Magazine Award, and an NSF CAREER Award. His students have been awarded three thesis or paper awards. He served a six-year term on the IEEE Signal Processing Society's Image and Multiple Dimensional Signal Processing Technical Committee, and he currently serves as permanent Co-Chair of the SPIE Wavelets conference series. Information on his forthcoming textbook coauthored with Martin Vetterli and Jelena Kovacevic is available at http://fourierandwavelets.org. | |
