Abstract:
A new High Efficiency Video Coding (HEVC) standard, also known as H.265 and MPEG-H Part 2, is on the way. HEVC provides a significantly higher coding performance than MPEG-2 and H.264/MPEG-4 AVC, especially for high-resolution video, and also includes various technologies to enable parallel encoding/decoding and to simplify implementation. Although the modules of HEVC exist in AVC, almost every module has been re-considered and many new and exciting state-of-the-art coding tools have been introduced. Many ideas behind such tools, whether accepted or not, are novel and inspiring to the research community. HEVC also presents many new challenges, including encoding optimization, mode decision, rate-control, hardware design, and error concealment, especially given its large and hierarchical block structure and significantly increased number of coding parameters.
In the DTV, HEVC application in broadcasting depends of the infrastructure for the previous digital broadcast standard. Are transmitter infrastructure and receiver base widely used? How soon will set-top boxes be commercially evaluable, and at what price? Is it reasonable to use terrestrial broadcast systems considering the level of their use and alternative DTV systems?
Dr. Isailovic developed through the years the special structured techniques for teaching MPEG standards. This will be presented in this lecture.
Lecturer:
Dr. Jordan Isailovic, Professor, Researcher, and Scientist, JRI Technology and California State University, is an author of two famous textbooks: Videodisc and Optical Memory Technologies, and Videodisc Systems: Theory and Applications (Prentice-Hall, 1985 and 1987, http://compressednews.com/dvd.htm). He has authored numerous technical articles and holds several patents on digital information storage techniques and video signal processing. He presented the world's first public engineering course on videodisc technology (January 1982) and taught the world's first graduate courses on videodisc and optical memories (CD, CD-ROM, etc.) at UC Irvine and California State University Fullerton. He developed a double density code, the "Jordan Code", on which three US patents are held.
His research projects include the following areas: three-dimensional optical memories, channel coding for optical recording, machine vision, image processing, testing methodology for visually-lossless compression, etc. For lectures, he has written four manuscripts: Optical Compact Systems (including CDs and CD-ROMs), Advanced Digital Systems Design, Guide to Frame Grabber Design, and Multimedia PC Architecture and Design.
Dr. Isailovic's current research primarily focuses on video compression – a subject closely related to his Ph.D. thesis in which, among other things, he established the theoretical limits for TV signal compression based on 3D predictive coding. As a consultant, he has evaluated a great number of MPEG (-1-2-4) encoders and decoders. For Advanced Interactive Inc. he designed the Non-Peg Interactive TV set-top box. He represented Packard Bell-NEC – where he worked as a Video Architect - in the DVD Copy Protection Technical Working Group (CPTWG), represented Lucas Film and Technicolor in MPEG, and is still active on the MPEG committee, SMPTE and CPTWG. He co-chaired MPEG Digital Cinema AHG and the SMPTE working group on DVD Authoring. Currently, Dr. Isailovic is consulting in the fields of digital cinema and video compression: evaluating/testing compression techniques, proposing system designs, participating in Standards committees on digital cinema, etc. Also, he serves as an expert witness in patent litigation: he assesses and evaluates patents and patent portfolio.
