ATI AvivoTM HD Technology
ATI AvivoTM HD is the advanced image and video processing and display
technology found in ATI RadeonTM HD GPUs and ATI TheaterTM video capture
processors. Specifically designed for HDTV and HD video enthusiasts, ATI
Avivo HD provides brilliant colors, sharp images, smooth playback of
Blu-rayTM* and HD video content, HDMI with built-in multi-channel
digital audio, and on some GPUs, Unified Video Decoding (UVD). UVD is
designed to enable a cool and quiet media PC with low CPU power
requirements and playback of HD 1080p content. HD Monitor is required
for full 1080p enjoyment.
HDMI Video and Audio
A system with an ATI RadeonTM HD 4800 Series graphics card can help
enhance the HD entertainment experience by providing a seamless
connection to an HDTV or home theater system. With built-in 7.1 surround
sound audio (AC3 / DTS ), the new GPUs and graphics cards support single
cable connection directly to a compatible HDTV, projector or receiver.
This single cable carries both the HD video and 8 channel audio for a
clean, high definition connection. Some graphics cards will be equipped
with an HDMI connector, while others will output the HDMI signal using a
special ATI Radeon DVI-I to HDMI adapter. These options give consumers
more options and flexibility when connecting their PCs to monitors or
home theaters for maximum enjoyment of HD content. The new GPU also
supports xvYCC color which can display a wider range of color when
connected to capable HDTVs.

ATI RadeonTM HD 4800 series GPUs offer full support for the new DirectX®
10 and DirectX® 10.1 API (Application Program Interface) from Microsoft;
ready to meet the demanding needs of new, next generation games. DirectX
10 is the first totally new DirectX in the last 4 years and brings
important graphics innovations that can be used by game developers for
the next generation of games. DirectX 10 introduces crisp, never-beforeseen
detail-rich images, visual effects and game dynamics capable of
accurately simulating the real world. No matter which ATI RadeonTM HD
4800 Series GPU you choose, you can be assured that games will look as
good as the developer intended!
