Abstract
The invention discloses a program editing method supporting H. 264 and based on the browser/server (B/S) architecture. The method includes extracting I frames of H. 264 and generating a video stream temporary file formed by the I frames; transmitting the video stream temporary file to a front page which performs video edition on a video file by using the video stream temporary file to obtain a first editing result of a video stream; and transferring the first editing result of the video stream to a back stage which processes the first editing result of the video stream to obtain a final program editing result. The program editing method supporting H. 264 and based on the B/S architecture is achieved, so that all the edition of programs is performed on the front page.
Description
Technical field
The present invention relates to the editing saving technical field in broadcasting and TV field, relate in particular to a kind of based on B/S framework support editing saving method and system H.264.
Background technology
Constantly perfect along with audio/video coding techniques and IP network transmission technology, the Digital Media business has obtained developing rapidly, and has developed into the core application in broadband.At present; The professional pattern that adopts centralized services of Digital Media of China Telecom is under this pattern, through based on C/S (Client/Server; Client/server) or C/S+CDN (Content Delivery Network, content distributing network) framework for the user service is provided.But along with the video traffic increasing demand increases, the system's investment under this framework increases severely, and the unconspicuous problem of output benefit also manifests day by day.
The B/S structure, promptly Browser/Server (browser/server) structure is the rise along with the Internet technology, to a kind of variation or the improved structure of C/S structure.Under this structure, user interface realizes through browser that fully a part of affairs logic realizes at front end, but main affairs logic realizes at server end.The B/S structure; It mainly is the WWW browser technology that has utilized continuous maturation; Multiple Script language (VBScript, JavaScript...) and ActiveX technology in conjunction with browser; Just having realized the power that needs complex proprietary software to realize originally with general browser, and practiced thrift development cost, is a kind of brand-new software system construction technology.
H.264 be ITU-T (International Telecommunications Union's telecommunication standards group) VCEG (Video Coding Experts Group; Video coding expert group) and the common digital video coding standard of formulating of new generation of the associating group of ISO (International Standards Organization)/IEC MPEG (Joint Video Team abbreviates JVT as).H.264 as one of coded format of HD video (High Definition TV abbreviates HDTV as), have broad application prospects in P2P Streaming Media field.For video traffic, H.264 later Development Trend mainly is based on.H.264 maximum advantage is to have very high data compression ratio, and under the condition of equal picture quality, compression ratio H.264 is more than 2 times of MPEG-2, is 1.5-2 times of MPEG-4.Compression performance means that identical data volume can represent the better pictures quality efficiently, perhaps can the transmission quality better pictures under the identical network bandwidth; Also mean, the video of equal in quality is provided, only need data volume (or bandwidth) still less.
But, the editing saving method that lacks based on the B/S framework in the prior art and support H.264 to encode, existing editing saving operation can not all be carried out on webpage.
Summary of the invention
In order to solve the shortcoming of above-mentioned prior art, main purpose of the present invention provides a kind of based on B/S framework support editing saving method H.264, makes whole edit operations of program are all carried out on the webpage of foreground.
