Description
Technical field
The present invention relates to the programme production technique field, particularly relate to and a kind ofly in figure broadcast process, look audio frequency and image separation playing system.
Background technology
In TV station's record and broadcast business in early days, the making of video-audio program and captions and broadcast are carried out on non-volume working terminal, video-audio program and captions are to handle according to the mode that mixes, is packaged into a program, captions and video-audio program mix in the program after packing is finished, can not carry out captions and the fractionation of looking audio frequency.Packing process does not separate caption information and audiovisual information.Such pattern causes us to waste a lot of times owing to the packing of captions is synthetic in the program making process.In the generative process of program, groundwork is the synthetic and processing of the special efficacy of video-audio program, and is not the synthetic work of captions and video pictures.For captions and the packing that mixes of looking audio frequency, directly caused the waste of a large amount of system times and resource.The a large amount of consumption of workload that so just makes whole station synchronization make broadcast is synthesized in the packing of program, causes operating efficiency to descend.
On the other hand, TV station also is that the record of returning that need carry out program is preserved for the program that broadcasts.And at present, the record mode of returning that adopts final captions and video pictures to mix also is very disadvantageous for the utilization again of program from now on.
Along with the appearance of technology such as MOS agreement, realized that video-audio program separated with the record and broadcast of captions afterwards, separation looked in promptly so-called word.And the video frequency program file that separates with captions preserved.Adopting word to look isolation technics, to make the program that is saved be clean, and also envoy's purpose record and broadcast efficient is greatly improved.
Similar with video and captions packing, existing looking also exists the merging broadcast to cause program production efficiency to reduce in audio frequency and the figure broadcast technology, and picture is played up the defective that quality descends.Therefore, prior art is badly in need of a kind of audio frequency and image separation playing system looked to remedy above-mentioned technological deficiency.
Summary of the invention
The problem to be solved in the present invention provides a kind of audio frequency separates broadcast with figure equipment of looking, is implemented in to look separating that audio frequency broadcasts and figure broadcasts in the figure broadcast process, thus the operating efficiency of raising broadcast process and the rendering efficiency of figure.
For achieving the above object, the embodiment of the invention proposes a kind of audio frequency separates broadcast with figure equipment of looking on the one hand, comprises with the lower part: the manuscript writing device is used for writing and generating of manuscript and figure; Separate and transmit processing unit, be used for separating treatment video-audio program material and figure, described separation transmits processing unit and specifically comprises video-audio program material link and graphics link, described video-audio program material link carries out the video-audio program material to be transmitted and handles, and described graphics link is carried out generation, transmission and the processing of graphic file; Wherein, described video-audio program material link comprises non-volume editor MOS rail and synthesis server again, described non-volume editor MOS rail, be used to carry out the correspondence editor of video-audio program material and MOS captions, described synthesis server is used to carry out the synthetic transmission of described video-audio program material and MOS captions; Look the audio frequency broadcasting server, be used to broadcast video-audio program; Graphics server is used to realize that the real-time rendering of figure and figure broadcast; Synthetic playing device is used for looking the figure that video-audio program that the audio frequency broadcasting server broadcasts and described graphics server broadcast and synthesizing described, and broadcasts.
Wherein, described graphics link comprises again: figure generates control module, is used for generating graphic file by filling in information such as masterplate, parameter and data source; The graphics server rendering module is used for described graphic file is carried out local real-time rendering, and carries out information interaction by generating control module with described figure, realizes the effect preview; The manuscript auditing module, whether the information data that is used to examine described graphic file is correct.
Wherein, the described audio frequency broadcasting server of looking receives the synthetic video-audio program material of described warp, and broadcasts.
Wherein, described graphics server comprises rendering module and broadcasts module, is respectively applied for real-time rendering and figure and broadcasts.
Wherein, described synthetic playing device comprises: broadcast the Control work station, be used to control and describedly look the audio frequency broadcasting server and described graphics server is adjusted captions graph text information and video frequency program file synchronously, and pass to described studio cut bank; The studio cut bank is used for the professional graphical information that will receive and video frequency program file and synthesizes and broadcast.
The technical scheme of the embodiment of the invention has the following advantages, because adopted and in figure broadcast process, looked audio frequency separates broadcast with figure method, the processing procedure of figure and video-audio program material is separated with the broadcast process, independently carry out respectively, thereby improved the efficient of described figure manufacturing-broadcasting system, and significantly improved the efficient of figure real-time rendering.
