Embodiment Construction

[0028] This application can be applied to various video coding standards, such as H.266, high efficiency video coding (high efficiency video coding, HEVC) (or H265), universal video coding (versatile video coding, VVC), audio and video coding standards (audio video coding standard, AVS), AVS+, AVS2 and AVS3, and various audio and video codec standards that will evolve in the future.

[0029] The mainstream video coding framework includes prediction, transformation, quantization, entropy coding, loop filtering and other parts, such as figure 1 shown.

[0030] Prediction is an important module of mainstream video coding frameworks. Prediction is divided into intra prediction and inter prediction. Prediction is divided into intra prediction and inter prediction. Intra-frame prediction uses the coded block on the current image frame to generate a reference block (or called a prediction block) of the current image block (hereinafter referred to as the current block), while inter...

Abstract

The invention provides a video processing method and device. The method comprises the following steps: determining a chrominance block to be coded or decoded; and taking the motion vector of one luminance block in the luminance blocks corresponding to the chrominance block as the motion vector of the chrominance block. By directly using the motion vector of one of the brightness blocks corresponding to the chrominance block as the motion vector of the chrominance block, the process of obtaining the motion vector of the chrominance block can be effectively simplified, so that the coding and decoding process of the chrominance block can be simplified, the coding and decoding complexity can be reduced, and the coding and decoding efficiency can be improved.

The copyright owner has no objection to the reproduction by anyone of the patent document or the patent disclosure as it exists in the official records and files of the Patent and Trademark Office. technical field [0003] The present application relates to the field of video processing, and more specifically, to a video processing method and device. Background technique [0004] In video compression, a video signal is decomposed into luma and chrominance components. Wherein, the resolution of the chroma component is halved or more reduced through the step of "chroma sampling". [0005] The video encoding process includes an inter prediction process. The inter-frame prediction process includes acquiring a motion vector (motion vector, MV) of the current block, and then searching for a similar block in ...
