The standard knitted, the most domestic AVS, the VC-1 of Microsoft, the VP8 etc. of Google.Identical, these
Standard all uses block-based hybrid encoding frame, fusion forecasting coding, transition coding and entropy code 3
Big coding techniques, waits piecemeal to encode image.
Predictive coding is the important coding techniques of video compress, according to prediction data source difference, and can be
Coded image is divided into I frame (infra-frame prediction frame, Intra), P frame (MB of prediction frame, Prediction), B
Frame (bi-directional predicted frames, Bi-Prediction).During as it is shown in figure 1, I frame is predicted coding, only with
The data of this frame are predicted, and can independently decode the when of decoding, are independent of other frames.P frame is carried out
During predictive coding, use the reconstruction image of an above frame encoded image as reference, P frame decoding time
Wait, it is necessary to wait the picture decoding of reference frame to complete to decode.When B frame is predicted coding, Ke Yitong
Shi Caiyong previous frame and subsequent frames make reference, and become bi-directionally referenced frame, and B frame decoding is reference before needing
Could decode after frame and later reference frame all successfully decodeds.P frame, B frame coding time except making of other frames
Reference, it is also possible to as I frame sample makes reference with these frame data, selects both optimal situation just.
In monitor video, the picture that major part gathers is fixing scene, and region static on picture is many,
It is referred to as background；The part of motion is few, referred to as prospect (or target), usually moving object.On the other hand,

Improve the compression efficiency of monitor video, Objective extraction and Video coding can be combined, it would be desirable to compile
The picture of code is divided into background parts and target part, and target part is also referred to as foreground part.For background portion
The coding divided, uses background image to make reference, can be with large increase code efficiency.Fig. 2 is based on background frames
The coded reference relation of reference, I frame originally changes R frame (refresh frame) into, be no longer all use in frame pre-
Survey technology, is referred to background frames and carries out interframe encode, and can only be with reference to background frames.Other P frame, B
Frame referring-to relation is constant, additionally can also encode with reference to background frames.G frame (background frames) under normal circumstances
Interval is very big, as long as scene does not has big change, such as light cataclysm, The Cloud Terrace conversion in theory, all may be used
To use this background frames to encode.By such thinking, the compression effect of video can be improved further
Rate.
In the scheme of background frames reference encoder, background frames (G frame) place different from other frames is exactly
It may not be original in video sequence existence, can pass through Background generation technology or select static
The modes such as frame produce.Such background frames, when Stochastic accessing, is not required to display in fact, and if aobvious
Show the R frame of Stochastic accessing, but in prior art, participate in the picture frame of coding, be all to need display
