Description
Technical field
The present invention relates to video recorded broadcast field, relate in particular to a kind of method and device of video record.
Background technology
In the video compression coding standard of present main flow, in order to improve compression ratio, all adopted the coding method of inter prediction, namely the picture frame of back uses the picture frame of front as predictive frame, then the residual values after prediction is encoded, such image is called inter frame image.In the actual coding process, some images are also arranged not with reference to other two field picture, only carry out predictive coding in frame, as the first frame coded image, such image is called I picture.Also some I pictures of radom insertion in cataloged procedure as required.Due to the dependence of inter frame image to the predicted picture of front, must first decode all predicted pictures, the inter frame image of then could decoding.
In the process of on-line meeting, in order to preserve minutes, often need conference scenario is carried out video record.As previously mentioned, due to present Video coding mode, the decoded picture of back has dependence to the predicted picture of front, play for making the decoding that image after coding can be complete, present method is, directly MCU (Multipoint Control Unit, multipoint control unit) or the received complete video code stream that is used for watching in real time of terminal are preserved, as recorded content.Adopting this kind method to record the video content that gets off, is exactly the complete video content that begins from conversation in the middle of meeting, can't realize realizing recording video content since any time.
For realizing since any time recording video content, the following two kinds of methods of available technology adopting, comprise: the first, regularly insert the image of some intraframe codings at coding side, preserve in decoding end the video code flow that begins from I picture and supply subsequent playback as recorded content; The second, increase a camera in output end of image, the image of output is rebuild in picked-up, then this image is encoded again, and the code stream after coding is deposited in the recording and storing device.
State in realization in the process of video record, when adopting the method for regularly inserting the image of some intraframe codings at coding side, when realization realizes the recording of video content since any time, because the I picture compression ratio is low, and changed the original coded system of coding side, so the process of video record can affect actual video effect; When adopting the method that increases a camera in output end of image, when realization realizes the recording of video content since any time, increased peripheral hardware, and because needs are encoded to reconstructed image again, greatly increased computational complexity, and due to the compression of cataloged procedure, record picture quality and greatly reduce.
