Abstract
An enhanced prediction direction method and encoding syntax for B-pictures in state-of-the-art video compression. In bi-directional prediction, instead of using one motion vector (MV) from list 0 and one from list 1, both may be alternatively drawn from list 0 or list 1, and this information communicated to a decoder similarly configured for recognizing the generalized syntax.
