Problems solved by technology

[0003] At present, the subtitle editing systems of various TV stations generally edit directly according to templates, lack the function of subtitle overlap detection, and the management of templates is relatively simple
Since the subtitles of some programs are automatically broadcast when the broadcast time is reached, once there is a problem of conflicting with other subtitles in the display position during broadcast, it will cause broadcast accidents and affect the broadcast quality of TV programs.

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] like figure 2 As shown, the present invention divides the screen area according to the position where the subtitles are displayed on the TV screen, and is divided into a pull-bar information area 1, a guide information area 2, an advertisement information area 3, a scrolling subtitle information area 4, and a TV drama prompt information area 5. The division of regions can be different according to the needs of different TV stations, and then divide and manage the templates according to the regions. In this way, different channels correspond to different regions, and the regions correspond to different templates (one channel corresponds to multiple regions, and one region corresponds to multiple templates).

[0020] The subtitles that TV stations need to edit are generally divided into program subtitles (subtitles are hung under the p...

Abstract

The invention belongs to the subtitle editing technology of TV programs, in particular to a program subtitle collision detection method based on region division, which comprises the following steps of: dividing a screen region according to the positions of subtitles displayed on a TV screen, and dividing and managing a subtitle template according to the regions to form a structure that different channels correspond to different regions but the areas correspond to different templates; when the subtitles are edited, firstly selecting a region and then selecting a template below the region to edit; the subtitle collision in the same region is detected by set detection conditions, thereby avoiding the overlap display of the subtitles and improving the safety of subtitle editing and program broadcast.

Description

technical field [0001] The invention belongs to the subtitle editing technology of TV programs, in particular to a subtitle conflict detection method based on area division. Background technique [0002] TV subtitle editing and broadcasting technology occupies an important position in the technical development of the radio and television industry. Computer-based TV graphic production and broadcasting equipment is an important part of the digitalization of the radio and television industry. The production and broadcasting system of TV graphics and texts based on computer technology has roughly experienced several stages such as simple two-dimensional flat subtitles, two-dimensional graphics with texture and dynamics, and the complete integration of high-quality two-dimensional and three-dimensional graphics. The application of the subtitle system covers all aspects of TV programs, including the production and broadcasting of live news programs, studio interview programs, vari...
