Method and system for broadcasting control of timing material of caption generator

Abstract

The invention, which mainly relate to the field of the manufacturing and broadcasting of broadcast television programs, provides a method and system for broadcasting control of a timing material of a caption generator. The method comprises: (1), reading a program list and a material timing program list by a broadcasting control system; (2), according to the program list and the material timing program list, obtaining a material by the broadcasting control system; and (3), carrying out loading and playing by the broadcasting control system. Moreover, the system is composed of a program list reading unit, a material obtaining unit, and a playing unit. The program list reading unit reads a video material list, a caption material list, a material timing program list and a caption material timing index list in the program list according to the program list content; the obtaining material unit obtains video materials and caption materials according to the lists and sends the materials to the playing unit; and the playing unit carries out playing. According to the invention, repeated invoking of the same kind of timing material attributes of a caption generator by a broadcasting control system can be simplified by invoking the material timing program list, thereby saving system resources.

Description

technical field [0001] The invention relates to the field of broadcasting and television program production and playing, in particular to a method and system for controlling the playback and control of subtitle machine timing material. Background technique [0002] In the field of radio and television program production and broadcasting, a large amount of subtitle synthesis processing is required in the process of program material production to meet the needs of program material broadcasting. The subtitle synthesis method in the prior art is that the broadcasting control system The control computer generates the program list file, and copies the program list file to the subtitle machine. The subtitle machine makes subtitles according to the program list file. On the one hand, because there is no communication between the broadcast control system and the subtitle machine, it needs to be manually moved Storage device, copy the program list file in the broadcast control machine...

AI Technical Summary

Problems solved by technology

[0004] When it is necessary to edit the unified material, the material can only be edited one by one, and the unified editing cannot be realized, and the attributes of the material cannot be managed and utilized in a unified way, resulting in a lot of duplication of labor and increasing the probability of errors

[0005] At the same time, since the information matching between the broadcast control system and the subtitle machine can only be carried out manually, the problem that the information between the broadcast control material and the subtitle cannot be corresponding in time is caused. On the one hand, this problem is not conducive to the timely editing of the material; There is a problem of file format incompatibility between the broadcast control system and the subtitle machine between different users, and it is impossible to make and edit program subtitles in different companies and different systems
