Abstract
An encoder sends binary information indicating whether a prediction mode is forward or not-forward for one or more macroblocks in an interlaced B-field. For example, the encoder sends forward/not-forward decision information at B-field level in a compressed bitplane. Sending forward/not-forward prediction mode decision information in a compressed bitplane at B-field level can reduce coding overhead for prediction mode coding. A decoder performs corresponding decoding.
