硬件加速播放的工作原理以及低端系统流畅播放HDTV的注意事项(5) nVidia MX420, 440, FX series
DXVA Support: the good news here is that ATI was heavily involved with Microsoft when it formed the DXVA standards for MPEG2 acceleration. The original Radeon supported the full feature set of what would become DxVA even before the standard was finalized. On the NVIDIA side, NVIDIA added a new video processor to their GeForce 4 MX series that is fully DXVA compliant. The GeForce 4 Ti was focoused on 3D gaming and so the silicon went to 3D piplines rather than the video processor the GF4MX had. By the GeForce FX series technology has progressed enough for NVIDIA to put the GeForce 4 MX's video processor into every one of the FX line.
