Abstract

The invention provides an encoding and decoding method, device and equipment. The method comprises the steps: a plurality of peripheral matching blocks pointed by a pre-configuration angle are selected from peripheral blocks of a current block for any motion information angle prediction mode of the current block based on the pre-configuration angle of the motion information angle prediction mode,wherein the plurality of peripheral matching blocks at least comprise a first peripheral matching block and a second peripheral matching block to be traversed; for a first peripheral matching block and a second peripheral matching block to be traversed, if available motion information exists in the first peripheral matching block and the second peripheral matching block, when the motion information of the first peripheral matching block is different from the motion information of the second peripheral matching block, the first peripheral matching block and the second peripheral matching blockare traversed; finally, the motion information angle prediction mode are added to a motion information prediction mode candidate list of the current block. Through the scheme of the invention, the coding performance can be improved.

Description

technical field

[0001] The present application relates to the technical field of encoding and decoding, and in particular, relates to an encoding and decoding method, device and equipment thereof. Background technique

[0002] In order to achieve the purpose of saving space, video images are transmitted after being coded, and a complete video coding method may include processes such as prediction, transformation, quantization, entropy coding, and filtering. Predictive coding includes intra-frame coding and inter-frame coding. Inter-frame coding uses the correlation in the time domain of the video to predict the pixels of the current image using the pixels of the adjacent coded image, so as to effectively remove the redundancy of the video time domain. In inter-frame coding, a motion vector is used to represent the relative displacement between the current image block of the current frame video image and the reference image block of the reference frame video image. For examp...
