Abstract

The invention relates to a video coding method and device, a video decoding method and device, electronic equipment and a system. The video coding method comprises the steps that in the process of coding a video, in allusion to a target frame to be coded, if it is detected that continuous N frames after the target frame are the same as the target frame, preset frame-level coding is performed on the target frame and the continuous N frames, wherein N is greater than or equal to 1, the frame-level coding refers that block-level coding is performed on one of the target frame and the continuous Nframes and that frame-level quantity statement is performed on the repeated frames corresponding to the target frame; and a first video frame different from the target frame after the target frame isenabled to serve as a next target frame to be coded after the frame-level coding is completely executed. According to the invention, the scheme can improve the coding efficiency in the coding processunder 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,...
