Description
Technical field
The present invention relates to the video technique field, relate more specifically to the video coding system and the method for video coding of a kind of single channel input multichannel output.
Background technology
The video coding technique of different resolution is an important research direction during modern video monitoring and IP shooting are used.In these were used, the user required to gather the single channel vision signal at the video coding system input usually, and exports the compressed and multiplexed code stream of different spaces size at output.Like this, can watch the image of different quality according to different demands in decoding end.This application requirements adds resampler and a plurality of video encoder in video coding system, resampler is used to generate the vision signal of two or more different spatial resolutions, compresses simultaneously via a plurality of video encoders then, produces the multi-channel video compressed bit stream.
In above-mentioned application, video coding system is owing to need a plurality of video encoders, so the requirement of operational capability is multiplied, corresponding hardware and software cost also improves greatly.Therefore, how increasing under the prerequisite of coding operand not significantly, finishing the video compression of multichannel different spaces size, is a main difficult problem that effectively realizes this system.
Another problem that the vision signal of multichannel different spaces size is compressed is, different along with time and scene, and the user also needs to adjust to the coding quality of low resolution and high-resolution video sequence.Whether the user may select arbitrarily to need high-resolution video sequence is carried out high-quality coding, or only needs the compressed video stream of the low resolution of outputting high quality.Therefore, in video coding system when design, need provide such selection that is provided with in real time to the user.
In such video coding system, effectively solve above two problems, must design an advanced person's model selection algorithm.Mode selection module is one of most important component in the general video encoder, and the quality of its design will directly have influence on code efficiency and decoded image quality.
