Abstract

The invention provides a video coding processing method, which comprises the following steps: allocating code rate of each space domain layer in space domain-mass domain scalable video coding; establishing a code distortion model of a mass domain layer to be coded in each space domain layer according to the relation of code distortion of the mass domain layer to be coded and a mass domain reference layer thereof; establishing a code rate model of the mass domain layer to be coded by analyzing the relation of code rate of the mass domain layer to be coded and the mass domain reference layer; and allocating the code rate of the mass domain reference layer and the mass domain layer to be coded according to corresponding code rate of the space domain layer and the code distortion model and thecode rate model of the mass domain layer to be coded. The invention also provides a video coding processing device. The method and the device realize the code rate optimized distribution based on thecorrelation of code layers, can make the coding efficiency maximized, and further optimize the coding performance of scalable coding.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a method and device for video encoding processing. Background technique [0002] As an extension of the new-generation video compression coding standard H.264 / AVC, the scalable video coding (Scalable Video Coding, SVC) technology was formally standardized in July 2007. At present, H.264 / SVC supports the scalability in three dimensions of time domain, space domain and quality domain, and basically realizes the balanced design of decoder complexity and coding efficiency, and the video size (spatial domain) based Layering is the basic structure of the technology. [0003] In spatial scalability coding, H.264 / SVC follows the traditional multi-level coding method: first, the video sequence of the original size is decomposed (down-sampled) to obtain several sub-sequences with different spatial resolutions, each resolution Each rate corresponds to a spatial coding layer. Since...
