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.
