Abstract

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.

Description

technical field [0001] The present invention relates to the technical field of video image processing, in particular to a video image encoding processing, decoding processing method and device, and an encoding and decoding system. Background technique [0002] In the future, people's demand for the transmission and storage of high-definition video images will show explosive growth. However, the development of information network infrastructure such as the Internet, communication networks, and broadcasting networks is relatively lagging behind, and network bandwidth is still a bottleneck. Based on this fact, the next-generation video coding standard will focus on high-definition and ultra-high-definition video, and greatly improve the efficiency of video image coding and compression, so as to alleviate the contradiction between the increase in bandwidth demand for high-definition video image transmission and the development of information network infrastructure. How to improv...
