METHOD, APPARATUS AND SYSTEM FOR VIDEO IMAGE ENCODING AND DECODING

摘要

A method, apparatus and encoding-decoding system for video image encoding processing and decoding processing are provided by the present invention. The encoding processing method includes: performing down-sampling disassembly on the macro block of a video image frame to obtain a plurality of blocks which at least include a first block, a second block and a third block; performing intra-frame predictive encoding processing on the first block to obtain the reconstructed image value of the first block; by using the reconstructed image value of the first block as a reference, performing predictive encoding processing on the second block to obtain the reconstructed image value of the second block; by using the reconstructed image value of the second block as a reference, performing predictive encoding processing on the third block. The embodiments of the present invention can sufficiently utilize the correlation among pixels, and improve prediction precision and the encoding compression efficiency of the video image.
