Abstract

The present application relates to a video encoding and decoding method, device, electronic equipment and system. The video decoding method includes: in the process of encoding the video, for the target frame to be encoded, if the target frame is detected and the consecutive N frames are the same as the target frame, the target frame and the consecutive N frames are detected. Preset frame-level encoding; wherein, the N is greater than or equal to 1, and the frame-level encoding is: performing block-level encoding on the target frame and one of the consecutive N frames, and repeating the corresponding target frame The number of frames is declared at the frame level; after the frame-level encoding is performed, the first video frame following the target frame and different from the target frame is used as the next target frame to be encoded. It can be seen that through this solution, the coding efficiency in the coding process can be improved under the premise of ensuring the coding quality.

Description

technical field [0001] The present application relates to the field of video processing, and in particular to a video encoding and decoding method, device, electronic equipment and system. Background technique [0002] Digital video technology is widely used in communication, computer, radio and television and other fields, because video is composed of a series of video frames, each video frame is usually a complete image, and there are identical or similar images in the same image or adjacent images. content, prompting the generation of video coding technology. [0003] At present, video encoding includes block-level encoding for video. The principle of so-called block-level encoding is: divide the target frame to be encoded into data blocks, and then perform encoding sequentially from left to right and from top to bottom. [0004] In related technologies, in the process of performing block-level encoding on video, block-level encoding is performed on each frame. However,...
