Abstract

The invention discloses a video coding method, device and system and a computer readable storage medium, wherein the video coding method comprises the steps: constructing virtual motion information for an adjacent block of a current block, and enabling the adjacent block to be a time domain adjacent block, a space domain adjacent block or a time space domain adjacent block; obtaining an original matching block corresponding to the current block based on the virtual motion information; acquiring motion information of the original matching block; and coding the current block based on the motioninformation to obtain a code stream of the current block. According to the method, the influence of the motion information of the adjacent blocks is considered when the original matching block is acquired, so that the reasonability of the acquired original matching block is improved favourably, and the pixel prediction accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of video encoding, in particular to a video encoding method, device, system and computer-readable storage medium. Background technique [0002] The video can be compressed by the video coding technology to reduce the data volume of the video, reduce the network bandwidth during the video transmission process, and reduce the storage space. Wherein, the video encoding mode may include traditional inter-frame prediction mode, traditional intra-frame prediction mode, intra-frame block copy prediction, string matching prediction and other modes. [0003] Taking the traditional inter-frame prediction mode as an example, the existing inter-frame prediction process does not take into account the influence of adjacent blocks in the temporal and spatial domains on the original matching block when obtaining the original matching block. Contents of the invention [0004] The present application provides a v...
