Abstract

The invention provides a video encoding method, a video decoding method and related equipment. The video encoding method comprises the steps of: acquiring a current image, wherein the current image comprises a maximum coding unit, the maximum coding unit comprises a current maximum coding unit and a coded maximum coding unit, the current maximum coding unit comprises a current coding block, and the current coding block comprises a current string; storing pixels in the current coding block by using a first part of a storage space with the size of M*W, and storing at least part of coded blocks in the coded maximum coding unit and the current maximum coding unit by using a second part of the storage space, wherein M is a positive integer greater than or equal to W; and searching a reference string of the current string in the second part to obtain a predicted value of the current string according to the reference string, and encoding the current string.

Description

technical field [0001] The present disclosure relates to the technical field of video encoding and decoding, and in particular, relates to a video encoding method, a video decoding method, electronic equipment, and a computer-readable storage medium. Background technique [0002] On the one hand, the Internet is about to enter a new era of 5G (5th generation mobile networks or 5thgeneration wireless systems, 5th-Generation, fifth-generation mobile communication technology), and images (videos) appearing in various Internet applications have become the main consumers of Internet bandwidth . In particular, the image traffic on the mobile Internet is increasing day by day, and there will be explosive growth in the 5G era, which will inject new and powerful impetus into the accelerated development of image coding and decoding technology. At the same time, it also poses many severe new challenges to the image coding and decoding technology that have not been encountered in the p...
