Abstract:
A predictive encoding method of video data, in which one of a global motion-compensating process for predicting a global motion of the whole frame and a local motion-compensating process for predicting a local motion of each block in a frame is selectively performed, wherein:when a current block to be processed is not block-skipped, if the current block is interframe-encoded, then a code word for indicating the prediction mode is inserted in an encoded data sequence of the current block, the code word indicating which of the global and local motion-compensating processes was chosen for interframe-encoding the current block, and the code word inserted after another code word indicating the encoding mode of the current block; and if the current block to be processed is intraframe-encoded, then the code word for indicating the prediction mode is not inserted in the data sequence; and when the current block to be processed is block-skipped, the global motion-compensating process is always chosen so as to perform interframe encoding, and in the skipped block, the code word for indicating the prediction mode is not inserted in the data sequence.
