METHOD AND APPARATUS FOR ENCODING A PICTURE SEQUENCE USING PREDICTED AND NON-PREDICTED PICTURES WHICH EACH INCLUDE MULTIPLE MACROBLOCKS

摘要

MPEG, most of the video frames are encoded in inter mode. Typically, the error propagation is prevented, and a video frame to allow access points to the start of the video sequence is encoded in intra mode. However, it is sufficient only the pixel block in the intra mode that is utilized for the at least one pixel in accordance with the present invention predicting some future picture content information encoded by only the intra frame, the other blocks can be encoded in inter mode there. In order to check whether any blocks in the intra frame can be encoded in inter mode, motion compensation pre-analysis of the subsequent P frame is performed, which, because of any pixel in the predetermined block is not used for the prediction of the subsequent P picture is to find a block that does not need to be encoded in intra mode.
