Embodiment Construction

[0017] The inventors of the present invention aim at the problems of mixed production and broadcast of video and audio programs and graphic information in the existing broadcasting mode of radio and television programs, resulting in the waste of system resources and production time and the reduction of graphics rendering efficiency. During the broadcasting process, video, audio and graphics are broadcast separately, thereby reducing unnecessary consumption of system resources and improving graphics rendering efficiency.

[0018] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0019] like figure 1 As shown, it is a method for separate broadcasting of video and audio and graphics during the graphic broadcasting process of an embodiment of the present invention. Through this embodiment, TV station program production efficiency and preservation quality can be improved. This embodiment...

Abstract

The invention discloses a method for separately broadcasting a video-audio and a picture during a picture broadcasting process including the following steps: processing a video-audio program materialand pictures in a picture preparing and broadcasting system through different links; respectively transmitting the video-audio program material and pictures to a video-audio broadcasting server and apicture broadcasting server; after passes through the examination, a manuscript generates a broadcasting serial list which is transmitted to a broadcast control working station. The video-audio program material of the video-audio broadcasting server and the pictures of the picture broadcasting server are subject to signal mixing through switching channels under the control of the broadcast controlworking station so as to realize broadcasting. The embodiment of the invention leads the processing process and broadcasting process of the picture and video-audio program material to separate and implement respectively by adopting the method of separately broadcasting the video-audio and the picture during the picture broadcasting process; thereby improving the efficiency of the picture preparing and broadcasting system and greatly improving the real time render efficiency of the picture.

Description

technical field [0001] The invention relates to the technical field of program production, in particular to a method for separately broadcasting video, audio and graphics. Background technique [0002] In the early production and broadcasting business of TV stations, the production and broadcast of video and audio programs and subtitles were carried out on the non-editing work site. Subtitles and video and audio programs in the packaged program are mixed together, subtitles and video and audio programs cannot be split. The packaging process does not separate subtitle information from audio and video information. This mode caused us to waste a lot of time in the process of program production due to the packaging and synthesis of subtitles. In the program generation process, the main work is the synthesis and processing of special effects of video and audio programs, rather than the synthesis of subtitles and video images. For the mixed packaging of subtitles and video and ...
