发明名称 Compression of motion vectors
摘要 In a process for reducing the data rate of motion vector information, the components of the motion vectors are quantised, the quantised values are compressed and transmitted and the quantisation errors are additionally transmitted, whenever sufficient channel capacity is available. When not transmitted, the quantisation errors may be recreated at the encoder receiving the transmission. Where appropriate vectors may be translated to equivalent velocity values and passed through a linear transform, further reducing the required bit capacity.
