Embodiment Construction

[0015] The inventors of the present invention aim at the problems of separating and broadcasting video and audio programs and graphics information in the existing radio and television program editing and broadcasting mode, resulting in the waste of system resources and production time and the reduction of graphics rendering efficiency. During the process, video, audio and graphics are broadcast separately, thereby reducing unnecessary consumption of system resources and improving graphics rendering efficiency.

[0016] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0017] Such as figure 1 As shown, it is a schematic diagram of a device for separately playing video, audio and graphics during the graphics playing process according to an embodiment of the present invention. The invention of the nonlinear editing system is to separate video, audio and graphics during the graphics pla...

Abstract

The invention discloses a video / audio and graphics separating broadcasting system, which comprises a manuscript composing device used for the composition and the generation of a manuscript and a graphics, a separating transfer processing device used for separating and processing video / audio program source material and the graphics, a video / audio broadcasting sever used for broadcasting a video / audio program, a graphics sever used for realizing the real-time coloring of the graphics and the graphics broadcasting, and a synthesizing broadcasting device used for the signal mixing of the video / audio program and the graphics which are respectively broadcasted and broadcasting. Through adopting video / audio and graphics separating broadcasting equipment in the graphics broadcasting process, the embodiment of the invention leads the processing procedure and the broadcasting process of the graphics and the video / audio program source material to be separated, thereby the efficiency of a graphics drawing and broadcasting system is improved, and the efficiency of the real-time graphics coloring is greatly improved.

Description

technical field [0001] The invention relates to the technical field of program production, in particular to a separate broadcasting system for video, audio and graphics during the graphics broadcasting process. 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 mixe...
