Video Compression: Evaluating System Tradeoffs with H.264, VC1, and other Advanced Codecs

Thursday, July 21, 2005

11:00am PT/ 2:00pm ET

--------------------------------------------------------------------------------

Overview

Not all codecs are created equal in terms of the tradeoffs they make between compression rates, encode/decode processing requirements and key system factors such as latency. This Net Seminar will provide a brief introduction to how video compression is achieved and insight into why advanced video codecs and specific profiles within these codecs are better suited for certain applications. Codecs discussed will include H.264 (aka MPEG-4 AVC), VC-1 (aka Windows Media Video 9), MPEG, and others.

Discussion topics will include: Microsoft`s VC1 versus H.264 -- is there any difference from a DSP system point of view? Why does encoding require so much more processing power than decoding? How do resolution and frame rates factor in? Why are some codecs better suited for certain applications? What are the advantages of alternative video codecs from DivX, On2, and Real Networks. Can DSPs handle any codec, or do some require more computing power than DSP can provide? How does an engineer obtain codec software to work with a given processor?
