Today, NVIDIA has enabled new PureVideo technologies geared towards high-defintion video acceleration, including hardware acceleration for the H.264 specification.

The new technologies provide hardware acceleration for decoding H.264, VC-1, WMV and MPEG-2. H.264 is also known as the AVC (advanced video codec) specification, or MPEG-4 Part 10 and is one of the digital video codecs that have been specified for the upcoming Blu-ray and HD DVD formats, with VC-1 being the second codec adopted by the DVD Forum for use in HD DVDs.

Along with hardware-accelerated high-defintion video decoding, the new PureVideo technologies perform post-processing techniques on the decoded HD content. These include spatial-temporal de-interlacing and inverse telecine.

NVIDIA's PureVideo team has been working closely with the two big players in the video playback arena - namely InterVideo and CyberLink - along with one of the world's largest DVD authoring studios, Nero software, in order to include PureVideo acceleration their H.264 codecs.

The features are available in the latest driver providing you've got a GeForce 6-series (or newer) video card. The technologies are also available to owners of motherboards featuring the GeForce 6150 IGP. You can experience these new features in Forceware 84.12, which are available from NVIDIA's nZone download portal.

Having these features available to nForce 430 / GeForce 6150 motherboards means that NVIDIA claims the title for the world's first integrated high-definition video decoder with hardware acceleration.

Of course, we can't forget that ATI is also devoted to high-definition video decoding and connectivity with its Avivo technology, which has accelerated high-definition content ever since it came to market around the time that Radeon X1000-series launched.

Download the drivers and check out some H.264 streams from Apple's website, and also from Nero's homepage too - let us know your experiences in the forums.
