Universal Video Decoder 2.0

Universal Video Decoder 2.0

Always worth a mention is UVD, short for Universal Video Decoder. With proper 3rd party software like WinDVD or PowerDVD you can enable support for UVD 2.0 which provides hardware acceleration of H.264 and VC-1 high definition video formats used by Blu-ray and HD DVD. The video processor allows the GPU to apply hardware acceleration and video processing functions while keeping power consumption & CPU utilization low.

You will have sheer decoding precision on the Radeon 5000 series. Low CPU utilization whilst scoring maximum image quality. One improvement has been made as well; you can now for example upscale your 1920x1080 streams fine to a 2560x1600 sized monitor (no more black borders).

New in the GPU architecture of the series 5000 is an updated video engine. It's really not massively different opposed to the old UVD engine, yet has two new additions for post-processing, decoding and enhancing video streams. Dual stream decoding is one of the new features. For example, if you playback a Blu-ray movie and simultaneously want to see a director's commentary (guided by video) you can now look at both the movie and in a smaller screen see the additional content (like picture-in-picture). Obviously this is Blu-ray 2.0 compatibility here, and the additional content is an actual feature of the movie. But definitely fun to see.

New in Enhanced UVD 2.0

• Hardware acceleration decode of two 1080P HD streams
• Compatible with Windows Aero mode - playback of HD videos while Aero remains enabled
• Video gamma - independent gamma control from Windows desktop.
• Brighter whites - Blue Stretch processing increases the blue value of white colors for bright videos
• Dynamic Video Range - Controls levels of black and white during playback

A recently added feature also is Dynamic Contrast Enhancement. It does pretty much what the name says; Dynamic Contrast Enhancement technology will improve the contrast ratios in videos in real-time on the fly. It's a bit of a trivial thing to do, as there are certain situations where you do not want your contrast increased.

Another feature is Dynamic Color Enhancement. It's pretty much a color tone enhancement feature and will slightly enforce a color correction where it's needed. We'll show you that in a bit as I quite like this feature; it makes certain aspects of a movie a little more vivid.

Directly tied to the UVD engine is obviously also sound. AMD's Radeon series 3000, 4000 and 5000 cards can pass lossless sound directly through the HDMI connector. This has been upgraded as it's now possible to have 7.1 channel lossless sound 192kHz / 24-bit. The HDMI audio output follows HDMI standard 1.3a and now also supports Dolby True HD and DTS-HD audio. Obviously there is also support for standard PCM, AC-3 and DTS.

To be able to playback high-def content you'll still need software like WinDVD or PowerDVD, a HD source (Blu-ray player) and a HDCP monitor or television.
