ABSTRACT:
Picture-signal encoding methods and systems are disclosed for encoding interlaced scan picture signals. A first one of a pair of interlaced odd and even fields of one frame, as well as a field of another frame are encoded. The second one of the pair of interlaced odd and even fields is encoded such that at least a portion is encoded through bidirectional prediction from three fields. Decoding methods and systems are disclosed for decoding the picture-signal encoded as described above. Record media storing the encoded signals are also disclosed.
