ATI Avivo
As Avivo , AMD describes a video platform introduced with the Radeon X1300 to improve the multimedia capabilities of ATI's graphics cards (quality and flexibility). The further development is marketed under the name Avivo HD .
Avivo
In contrast to its successor, Avivo does not need an independent video processor. With Avivo there is the possibility of video acceleration via the pixel shader units of the respective graphics processors . Avivo enables hardware-accelerated decoding of video material , for example H.264 (with high definition resolutions) or MPEG-4 . Hardware-accelerated encoding is also possible using the Windows XP operating system and the ATI Radeon X1 series . There are also some tools to enable the use of this platform, the best known of which is Avivo XCode .
Avivo HD
An extended Avivo system that requires a Unified Video Decoder (UVD) is called Avivo HD . The Radeon HD 2900 graphics cards, which claim the new Avivo HD logo for themselves, but do not have a UVD, are a major exception . These cards are accelerated by the stream processors . However, practical tests have shown that the acceleration performance is roughly on par with the Avivo cards of the Radeon X1 series .
