ABSTRACT:
A system and methods for implementing an encoder suitable for use with the motion picture compression. The system includes a motion estimation apparatus which performs temporally interpolative motion estimation. The temporally interpolative motion estimation is performed by first performing unidirectional motion estimation between the current picture and one or more other pictures. The results of the unidirectional motion estimation alone, and not any picture data, are used to perform temporally interpolative motion estimation.
