Embodiment Construction

[0036] In order to solve the problem of ignoring the encoding correlation between the layer to be encoded and the reference layer existing in the prior art and thus losing certain encoding efficiency, the present invention provides a video encoding processing method: firstly, in the spatial domain scalable dimension , according to the order from high to low and considering the correlation between the reference layer and the layer to be coded, allocate the code rate of each space domain layer; then, in each space domain layer, according to the code rate of each time domain layer and its reference time domain layer Distortion relationship, establish the coding distortion model of each time domain layer; by analyzing the relationship between each time domain layer and the code rate of the reference time domain layer, establish the code rate model of each time domain layer; according to the code rate of the corresponding air domain layer, As well as the coding distortion model and ...

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-time domain scalable video coding; establishing a code distortion model of each time domain layer in each space domain layer according to the relation of code distortion of each time domain layer and reference time domain layers thereof; establishing a code rate model of each time domain layer by analyzing the relation of code rate of each time domain layer and the reference time domain layers; and allocating the code rate of each time domain layer according to corresponding code rate of the space domain layer and the code distortion model and the code rate model of each time domain layer. The invention also provides a video coding processing device. The method and the device realize the code rate optimized distribution based on the correlation 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...
