Intel thinks that ClearVideo will enhance Viiv.
Intel's upcoming G965 chipset, including the X3000 integrated graphics hardware, will support new ClearVideo technology to improve video playback on systems with integrated graphics.
ATI already has its Avivo technology and NVIDIA has PureVideo. ClearVideo will replicate some of the features of the existing technologies, but not others.
ClearVideo will do hardware de-interlacing, to improve the quality of broadcast content. It will also do colour correction and post-processing of two simultaneous streams, for picture in picture.
It will accelerate high definition content - but only MPEG 2 and WMV9. There is no H.264 or VC1 acceleration and this, coupled with the lack of HDCP support, makes it not ideal for working with next-gen HD-DVD or Blu-Ray discs.
The new chip uses what Intel calls a Video Mixing Renderer to apply its effects, rather than the traditional Overlay method used by other vendors. This allows the content to be processed within the frame buffer of the graphics hardware, to utilise the power of the pixel shaders within for things like alpha blending.
