Apparatus and Method of Motion-Compensated Predictive Coding |
摘要 |
<p>A moving picture signal is encoded by motion-compensated prediction using motion vectors for each motion-compensated block of the moving picture signal. The motion vectors are arranged into motion vector groups for each predetermined number of motion vectors. A code table is selected among a plurality of code tables for each motion vector group for encoding the motion vectors. Code table selection information is then output. The motion vectors is encoded by variable-length coding using the selected code table in accordance with the code table selection information. The code table selection information, the encoded motion vectors and an encoded predictive error signal are then multiplexed. <IMAGE></p> |
