Universal Video Decoder
From Wikipedia, the free encyclopedia
The Universal Video Decoder, or UVD in short, is the new video decoding unit from ATI Technologies to support hardware decode of H.264 and VC-1 video codec standards.

[edit] Existence
The existence of UVD was discovered by a Hong Kong computer website HKEPC hardware [1] with leaked presentation slides [2].
[edit] Xilleon
The UVD is reportedly to be based on an ATI Xilleon video processor, a 32-bit MIPS processor, for use in set-top boxes and digital TVs, for video decoding purposes. [1]
[edit] Features
The UVD, claimed by ATI, handles hardware Blu-ray and HD-DVD decoding on the GPU, up to a bitrate of 40 Mbps and Context-adaptive binary arithmetic coding (CABAC in short) support — see Features section of H.264 article for information, UVD also supports Dual stream decoding as well.
UVD features bitstream processing/entropy decode, frequency transform, pixel prediction and deblocking in the GPU, and reducing the effects of CPU specifications to the video qualities, instead of todays AVIVO technology which still passes the bitstream processing/entropy decoding to the CPU.
[edit] Availability
Originally, ATI was planned to implement the UVD in its RV550 series GPU aimed at mainstream market, with two different specifications in which one features HDMI and video out support another featuring DVI as well as video out support, and production was in December 2006, revealed by the slides. However, as of current date, no information about the release of related products.
There are speculations and reports that the models of upcoming RV610 GPU based graphics cards will implement the UVD, for hardware decoding of 1080p high definition contents [3].
