Abstract
A decoder includes circuitry configured to receive a bitstream, extract a header including a list of reference frames available for motion compensation, such as global motion compensation, determine, using the header, a motion model for a current block, the motion relative to a reference frame contained in the list of reference frames, and decode the current block using the motion model. Related apparatus, systems, techniques and articles are also described.
