PureVideo Decoder Platinum is een plug-in voor Windows Media Player waarmee hoge-definitiecontent door de gpu van een GeForce FX-, GeForce 6- of GeForce 7-videokaart gedecodeerd wordt, zodat de processor enigszins ontlast wordt. Begin dit jaar gaf nVidia op de Consumer Electronics Show een demonstatie van PureVideo. In die demonstratie werden een Intel Pentium D 830 en een GeForce 6600GT gebruikt voor het weergeven van een 20Mbps 1080p-stream: de load van de processor kwam daarbij niet hoger dan vijftig procent. Enkele dagen geleden hebben de ontwikkelaars van nVidia een nieuwe versie van PureVideo online gezet. Het gaat om versie 1.02-223, die vanaf deze ftp-map in drie verschillende edities gedownload kan worden. De release notes alsmede het changelog zijn hieronder gepubliceerd:
Release NotesChangelog
- Support for High Definition (HD) inverse telecine on compatible GPUs. See http://www.nvidia.com/page/purevideo.html for a list of supported GPUs.
- After installing the PureVideo Decoder and using the MCE "speaker setup" wizard to select 5.1 speakers, the audio will only be set in 2 channel stereo mode. This is a known issue with Microsoft Media Center Edition 2005 Update Rollup2. You may download this patch to fix the problem. The patch sets the proper value for 5.1 analog and must be run after using the speaker setup wizard. Note: You must run this patch every time after you run the wizard in order for the settings to remain active.
