lack the required processing capabilities for fully featured and smooth HD content
playback. HD content presents many challenges, including:
•
Large quantities of data processing
•
Computational complexity of algorithms for decode (i.e. CABAC) and
processing (i.e. advanced de-interlacing)
•
High power consumption levels as PC resources run intensively to decode HD
content, which can reduce battery life on notebooks and increase noise levels
caused by the fans of the system running to dissipate heat
•
HDCP and content protection mechanisms included on most HD media by
content providers (movies studios, cable providers...). If these requirements
are not supported properly, consumers may encounter issues to playback HD
protected content on their PCs.
In the past, the ATI Radeon™ X1000 series of graphics processors from AMD sought
to overcome these challenges by harnessing the GPU processing power hardware to
assist in the video decoding process. This innovation moved the major part of the
video decoding off the CPU, while taking advantage of the GPU graphics power for
post processing routines designed to enhance the image quality.
AMD continued its efforts to deliver an exceptional home entertainment experience
for consumers with the ATI Radeon™ HD 2000 series. These products leveraged
ATI's Avivo™ HD technology to provide a comprehensive solution to the challenges of
HD playback.
