Xbox 360 HD DVD player to use ATI decoder
An upcoming HD DVD player for the Xbox 360 console will rely
on ATI's decoder technology to play back HD DVD videos, the company
has announced. Naturally, this decoder technology relies on the Xbox
360's ATI-built "Xenos" graphics processor, which accelerates H.264
playback much like ATI's desktop Radeon X1000-series graphics cards.
Along with acceleration, ATI says the Xenos GPU can also apply "high-end
processing techniques" thanks to its unified shader architecture. These
techniques include comb filtering and automatic gain control, and ATI
says they help prevent color banding and video blockiness.
NVIDIA also announced an array of
video processing and acceleration features for high-definition media
last month under the PureVideo HD badge, but those features are intended
for its GeForce 7-series graphics cards only. According to slides
snapped by Beyond3D earlier this year, however, the NVIDIA-built RSX
graphics processor inside Sony's PlayStation 3 is based on the same architecture as GeForce
7-series cards. NVIDIA hasn't revealed anything about how the
PlayStation 3 will handle Blu-ray video playback, though.
