US Patent 9813700 Adaptively encoding a media stream with compound prediction

A method and apparatus for adaptively encoding a media stream with compound prediction are provided. Adaptively encoding a media stream with compound prediction may include decoding a first compound prediction use indicator for decoding a current frame, on a condition that the first compound prediction use indicator indicates that the encoded video stream includes a compound prediction mode for the current block, decoding the compound prediction mode for the current block from the encoded video stream and decoding the current block using the compound prediction mode, and on a condition that the first compound prediction use indicator indicates that the encoded video stream includes a second compound prediction use indicator, decoding the second compound prediction use indicator from the encoded video stream and decoding the current block based on the second compound prediction use indicator; and outputting or storing the decoded current block.
