A video coding method and device

Abstract

An embodiment of the invention provides a video coding method and device. The method comprises that aimed at a first value of a target coding parameter combination of a target object in a target layer, a coding result of the target object is obtained, and the target coding parameter combination includes at least two values; a first value to be jumped is determined according to the obtained codingresult; the first value to be jumped is jumped, a coding result corresponding to a not-traversed value is obtained under the condition there is a value not traversed in the target coding parameter combination; and according to a coding result corresponding to traversed values of the target coding parameter combination, a final coding result of the target object in the target layer is determined. Thus, a better coding result can be obtained by using schemes of the invention for video coding.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to a video coding method and device. Background technique [0002] With the continuous development of video services in multimedia applications and the continuous improvement of video cloud computing requirements, the data volume of the original video source is too large for the existing transmission network bandwidth and storage resources. One of the hotspots of research and application. Video coding, also known as video data compression, aims to eliminate various data redundancy of video signals. [0003] In the prior art, for a target coding unit, a single coding is usually performed based on a set of fixed coding parameter values. Once the above coding parameters are determined, the coding parameters of the coding unit will not be adjusted. In practical applications, the values ​​of the above encoding parameters are usually preset or determined according to the en...

[0003] In the prior art, for the target coding unit, a single encoding is usually performed based on a set of fixed coding parameter values. Once the above coding parameters are determined, the coding parameters of the coding unit will not be adjusted.

In practical applications, the values ​​of the above encoding parameters are usually preset or determined according to the encoding result of the previous coding unit. Although there are similarities between adjacent coding units in the video frame, the differences between these coding units There may also be large differences to a certain extent, so the coding parameters determined according to the previous coding unit may not be the best coding parameters for the current coding unit, which will easily lead to poor coding results of the current coding unit
