Abstract

The invention provides a video image coding / decoding methods and devices as well as a video image coding and decoding system. The coding method comprises the following steps: sampling and decomposing a macro-block of a video image frame so as to acquire a plurality of blocks which at least comprise a first block, a second block and a third block; performing the intra-frame predictive coding treatment on the first block so as to obtain the reconfiguration image value of the first block; performing the i predictive coding treatment on the second block by referring to the reconfiguration image value of the first block so as to acquire the reconfiguration image value of the second block; and performing the predictive coding treatment on the third block by referring to the reconfiguration image value of the second block. According to the embodiment of the invention, the relativity among pixels can be fully utilized, thus the prediction precision and the code compressing efficiency of the video image is increased.

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 encoding and decoding system. Background technique [0002] In the future, people's demand for the transmission and storage of high-definition video images will explode. However, the development of information network infrastructure such as the Internet, communication networks, and broadcasting networks is relatively lagging, and network bandwidth is still a bottleneck. Based on this fact, the next generation of video coding standards will focus on high-definition and ultra-high-definition video, greatly improving the compression efficiency of video image coding, in order to alleviate the contradiction between the growth of bandwidth demand for high-definition video image transmission and the development of information network infrastructure. How to improve the efficiency of video imag...
