Abstract:
1. A video decoder, comprising: a processor to receive a compressed video bitstream, said compressed video bitstream comprising a stream of pictures, wherein said stream of pictures comprises a current slice and a current block within said slice; said processor to pre-compute a chroma motion vector adjustment parameter for said current slice and to determine a motion vector component for said current block within said current slice using said pre-computed chroma motion vector adjustment parameter; said processor to determine if said current slice is a chroma slice, and when said current slice is a chroma slice, to receive information from first and second reference lists associated with said current slice; said processor to determine whether said current slice is a macroblock adaptive frame field (MBAFF) slice or a non-MBAFF slice, and when said current slice is a non-MBAFF slice, said processor to compute a first chroma adjustment array for said first reference list and to compute a second chroma adjustment array for said second reference list.
