Decoding, encoding, encoding and decoding methods, devices and equipment thereof

Abstract

The invention provides decoding, encoding, encoding and decoding methods, devices and equipment thereof. The decoding method comprises the following steps of if an inter-frame prediction filtering permission flag bit allows a current block to adopt inter-frame prediction filtering, and / or an enhanced inter-frame prediction filtering permission flag bit allows the current block to adopt enhanced inter-frame prediction filtering, and the current block meets an inter-frame prediction filtering condition, analyzing an inter-frame prediction filtering identifier of the current block from a coding bit stream of the current block, if the inter-frame prediction filtering identifier indicates that the filtering type of the current block is inter-frame prediction filtering, performing inter-frame prediction filtering processing on the current block to obtain a target prediction value of the current block, and if the inter-frame prediction filtering identifier indicates that the filtering type of the current block is enhanced inter-frame prediction filtering, performing enhanced inter-frame prediction filtering processing on the current block to obtain a target prediction value of the current block. Thus, the encoding 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 a decoding, encoding, 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 coding. The complete video coding method can include prediction, transformation, quantization, entropy coding, filtering and other processes, and predictive coding can include intra-frame coding and inter-frame coding. . Inter-frame coding is to use the correlation of the video time domain to predict the pixels of the current image by using the pixels of the adjacent coded image, so as to achieve the purpose of removing the redundancy of the video time domain. Intra-frame coding takes into account the strong spatial correlation between adjacent blocks, and uses the surrounding reconstructed pixels as reference pixels to predict the current uncoded blo...
