摘要： Motion compensated video encoding and decoding with motion vectors encoded with a reversible coarse code interleaved with an additional code, the coarse code occupying the even numbered bits and the additional code the odd-numbered bits of a codeword. Preferred embodiments include motion vector data partitioned from texture data and with motion vectors differentially encoded by use of an immediately preceding motion vector as a predictor.
