Description

technical field

[0001] The present invention relates to the communication field, in particular to a video processing method, encoding equipment and decoding equipment. Background technique

[0002] With the development of information technology, video signal has become the most important way for people to obtain information in their daily life due to its intuitiveness and high efficiency. Because the video signal contains a large amount of data, it needs to occupy a large amount of transmission bandwidth and storage space. In order to effectively transmit and store video signals, it is necessary to compress and encode video signals. At the same time, with the rapid development of high-definition television, web conferencing, IPTV, 3D television and other video services and the continuous improvement of people's requirements for video quality, video compression technology has increasingly become an indispensable key technology in the field of video applications.
