Information interaction method based on WEB services between heterogeneous systems of main control broadcasting line

Abstract

The invention relates to the television program recording and broadcasting technology in the field of broadcasting and television, in particular to an information interaction method based on web services between heterogeneous systems of a main control broadcasting line. In the method, programs in a video broadcasting system of the broadcasting line are transmitted into a caption broadcasting system by a standard XML file format protocol and WEB interface services, and the caption broadcasting system uses the programs to generate caption broadcasting items to enable the video broadcasting and the caption broadcasting to be closely coupled, thereby reducing the workload of manual manufacture of captions and avoiding the broadcasting accidents caused by manual misoperation; and on the other hand, some broadcasting control information of the caption broadcasting system, especially the information of the broadcasting-prohibiting periods of the captions of each channel are also transmitted into the video broadcasting system through standard service interfaces, thereby controlling the broadcasting switch of the captions and enhancing the security and the stability of caption broadcasting.

Description

technical field [0001] The invention relates to TV program production and broadcasting technology in the field of radio and television, in particular to an information interaction method based on WEB services between heterogeneous systems of master control and broadcasting lines. Background technique [0002] At present, all levels of radio and television production and broadcasting organizations are carrying out network construction. The core goal is to use the ever-changing IT technology to integrate the production, collection, editing, transmission, management, broadcasting, and production of TV programs. Multi-channel releases are organically integrated on one network platform to form a new technological process for TV program production. In different links, different IT technologies are adopted to optimize the process and improve the sharing rate of resources and improve the final program quality. broadcast quality. [0003] In 2006 and 2007, the State Administration o...

Problems solved by technology

Once a failure occurs, it will directly lead to broadcast accidents and bring bad social effects

[0012] Most of the subtitles need to be broadcast at precise timing in conjunction with the TV programs played by the video broadcasting system of each channel. However, the video broadcasting system will regularly adjust the program content and sequence. It is certainly impossible to automatically match the video title, and in this case, manual subtitle adjustment will become very difficult

[0013] The root of all the above problems is that the data interaction between the three business segments of "video broadcast system", "subtitle broadcast system" and "video switching and key mixing system" has not been realized in the broadcasting line of the TV station master control
