ATI Avivo
ATI Avivo is a set of hardware and low level software features present on the ATI Radeon R520 family of GPUs and all later ATI Radeon products. ATI Avivo was designed to offload video decoding, encoding, and post-processing from a computer's CPU to a compatible GPU. ATI Avivo compatible GPUs have lower CPU usage when a player and decoder software that support ATI Avivo is used. ATI Avivo has been long superseded by Unified Video Decoder (UVD) and Video Coding Engine (VCE).
==Background==
The GPU wars between ATI and NVIDIA have resulted in GPUs with ever increasing processing power since early 2000s. To parallel this increase in speed and power, both GPU makers needed to increase video quality as well, in 3D graphics applications the focus in increasing quality has mainly fallen on anti-aliasing and anisotropic filtering. However it has dawned upon both companies that video quality on the PC would need improvement as well and the current APIs provided by both companies have not seen many improvements over a few generations of GPUs. Therefore, ATI decided to revamp its GPU's video processing capability with ATI Avivo, in order to compete with NVIDIA PureVideo API.
In the time of release of the latest generation Radeon HD series, the successor, the ATI Avivo HD was announced, and was presented on every Radeon HD 2600 and 2400 video cards to be available July, 2007 after NVIDIA announced similar hardware acceleration solution, PureVideo HD.
In 2011 Avivo is renamed to ''AMD Media Codec Package'',〔(【引用サイトリンク】title=AMD Technology Glossary )〕 an optional component of the AMD Catalyst software. The last version is released in August 2012.〔(【引用サイトリンク】title=Previous AMD Display Drivers )〕 As of 2013, the package is no longer offered by AMD.
