Abstract

The invention relates to a video compression method and a video compressor. The method comprises the steps that video signal data are read through a video compressor, code stream data are generated, the video compressor carries out first prediction according to the read video signal data to generate first code stream data, and the video compressor carries out second prediction according to the read video signal data to generate first code stream data; and the video compressor performs operation according to the code stream data to form a code stream. According to the method, multiple prediction modes are adopted for the current MB, the image coding compression ratio can be improved for a complex texture area, and the theoretical limit entropy of prediction is further reduced.

Description

technical field [0001] The invention relates to the technical field of compression, in particular to a video compression method and a video compressor. Background technique [0002] The video signal contains a huge amount of information, which is difficult to store and transmit. Therefore, it is necessary to compress the video signal to facilitate the transmission of the video signal. Among them, the redundant information in the video signal includes time redundancy, space redundancy, and compression redundancy. And visual redundancy, etc., the starting point of video compression is to eliminate all kinds of redundancy to the greatest extent. [0003] Currently the main video signal compression standard is H.264 (MPEG-4Part10) standard. In recent years, on the basis of the H.264 standard, a new generation of video compression standard HEVC has emerged. HEVC still uses the hybrid compression framework adopted by H.264, inter-frame and intra-frame prediction compression: elim...
