Embodiment 1

[0036] figure 1 It is a schematic diagram of the principle of the traditional subtitle broadcasting system. In the use of traditional stand-alone subtitle machines, the upstream is the master broadcast control device, the downstream is connected to the stand-alone subtitle machine, and the terminal is the TV channel channel. The broadcasting of the traditional subtitle machine is relatively simple. You can manually edit the subtitle program list downstream, and then broadcast it, or you can manually add subtitles.

[0037] The traditional stand-alone subtitle machine needs to use two editing software in the two systems at the same time to edit the order twice, and there are mainly the following problems:

[0038] First, the resource consumption is serious, and the editing of the program list needs to be manually edited twice or manually imported;

[0039] Second, there are serious potential safety hazards. The manual editing operation method has low security in the long run,...

Embodiment 2

[0047] This embodiment is a subtitle editing method using the system described in Embodiment 1. The flow chart of the method is as follows Figure 4 shown.

[0048] The process of the method described in this embodiment is divided into two parallel processes: the process of adding subtitles, and the process of changing and adjusting subtitle content. These two processes respectively include two processes: a process of adding subtitles for subtitles related to video and audio, and a process of adding subtitles for subtitles not related to video and audio. Subtitles are handled differently. The key point is that the subtitle adding process related to video and audio and the subtitle adjustment process related to video and audio are oriented to the subtitle text data object embedded in a single sub-program unit data in the program list; however, it has nothing to do with video and audio The process of adding subtitles, and the process of changing subtitles not related to video ...

Abstract

The invention relates to a system and a method for broadcasting and controlling a subtitle; the system comprises a program list editing unit of a broadcasting control device; the program list editing unit is connected with a program list memory; the program list memory is connected with the program list broadcasting unit of the broadcasting control device; a subtitle editing interface is arrangedin the program list editing unit, and the subtitle editing interface is connected with a subtitle rendering unit; and a subtitle broadcasting interface is connected with a subtitle controlled rendering and broadcasting unit. The subtitle editing and broadcasting system constructed through the method improves the automation degree of the synchronous operation of channel on-line subtitle productionand broadcasting and a channel broadcasting control system, improves the safety of program broadcasting and saves resources; and particularly in a channel general control broadcasting control system,the invention provides a good work mode and the working method for producing subtitle content items in large scale and broadcasting control by frame.

Description

technical field [0001] The invention relates to a system and method for broadcasting and controlling integrated subtitles, a system and method for digital processing, and a system and method for adding subtitles during broadcasting of video images. Background technique [0002] With the increase of the overall business volume of TV stations, the number of subtitles to be broadcast is also increasing, and the forms of subtitles to be broadcast are also becoming more and more diverse, and most of the subtitles need to be broadcast accurately and regularly in conjunction with the video program list. These business requirements have put forward higher requirements for the editing and broadcasting mode of online subtitles in the master control broadcasting system, and the traditional stand-alone subtitle machine can no longer meet the business requirements. The traditional subtitle broadcast adopts a subtitle machine placed downstream of the channel broadcast. For the subtitle br...
