Claim Text:
1. An apparatus comprising a video bitstream stored on one or more non-transitory machine-readable media, the video bitstream characterized by: data representing predicted and bidirectional predicted picture frames that include picture regions in a compressed format, wherein a portion of the data that represent at least one picture region in the compressed format within a bidirectional predicted picture frame comprises: a signal indicating whether a bidirectional prediction mode for the at least one picture region is used; a signal indicating whether an interpolative motion vector prediction mode for the at least one picture region based on two referenceable frames in the video bitstream is used; a signal indicating whether a pixel interpolation mode using pixel weighting from the two or more referenceable frames in the video bitstream is used; and two pixel weight values for the pixel weighting, wherein the two pixel weight values are unequal.
