Abstract:
1. A computer-readable memory storing computer-executable instructions for causing a computer system when programmed thereby to perform: selectively enabling temporal motion vector (“MV”) prediction for deriving MV information for blocks of a current frame in a sequence of video frames; encoding the blocks of the current frame, including, for a given block of the blocks of the current frame, encoding the given block of the current frame using motion compensation with derived MV information relative to a reference frame to determine a motion-compensated prediction for the given block, wherein: and wherein at least one of the blocks of the current frame is encoded using motion compensation with derived MV information derived using spatial MV prediction; and outputting encoded data for the blocks of the current frame, including signaling information in the encoded data that indicates whether temporal MV prediction is enabled for the deriving the MV information for the blocks of the current frame.
