The method includes the steps that video data are received and divided into multiple frames; a Lagrange multiplier of a current prediction block in a current coding block is calculated, wherein the current prediction block is a video signal in the current coding block, the current coding block is located in the current frame, and the current frame is one of the frames; the Lagrange multiplier of the current prediction block is used for coding the current prediction block through a rate distortion optimization algorithm, so that a coding result of the current prediction block is acquired; the coding result of the current prediction block is sent to the decoding end. The code compression efficiency can be improved through the video processing method, the coding device and the decoding device.

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.

Problems solved by technology

However, the Lagrange multiplier of the coding block is determined according to the local characteristics of the coding block, resulting in inaccurate prediction of the prediction block located in the coding block when using the Lagrangian multiplier of the coding block for motion estimation. This leads to a large residual error of the prediction block, which further leads to a large bit rate consumed by encoding the residual error, resulting in low video coding efficiency
