Abstract: A system, apparatus, method, and article to process a chroma motion vector are described. The apparatus may include a video decoder. The video decoder includes a processor to receive a compressed video bitstream. The compressed video bitstream includes a stream of pictures. The stream of pictures includes a current slice and a current block within the slice. The processor pre-computes a chroma motion vector adjustment parameter for the current slice and determines a motion vector component for the current block within the current slice using the pre-computed chroma motion vector adjustment parameter.

Abstract: Apparatus, systems and methods for hardware accelerated compressed video bitstream escape code handling are disclosed including an apparatus comprising a bitstream parser (BSP) to parse a bitstream of compressed video data. The BSP includes circuitry to extract uncompressed run and level data from the bitstream when the BSP detects an escape code in the bitstream. Other implementations are disclosed.
