Abstract

The invention provides a method and device for broadcasting a subtitle through data grouping and dynamic replacement. The method comprises the following steps of: detecting a selected field in a database table to obtain corresponding field content; receiving the selection of a user to the field content, and marking data records with the selected field content in the database table; querying the data records with the selected field content through SQL (Structured Query Language) sentences, and generating a first data table for the group of data records; and extracting data from the first data table as the content of subtitle pixels to broadcast subtitles. According to the method and device provided by the invention, the user does not need to compile different SQL sentences to query data every time, so that convenience is provided for the user during operation, the work load is reduced, and the extraction speed of data is increased.

Description

technical field [0001] The invention relates to the technical field of radio and television, in particular to a subtitle broadcasting method and device for dynamically replacing data packets. Background technique [0002] With the continuous development of video and multimedia technology, subtitle production has become more and more popular in the field of TV program production, and the technical production indicators have become higher and higher, and its uses have become more and more extensive. The most widely used subtitle production is the program subtitle of TV stations. Production and subtitling of film and TV series. [0003] For some special programs, such as sports events, live broadcasts of evening parties, etc., the real-time requirements for subtitle broadcasting are relatively high. Therefore, it is necessary to quickly switch between subtitles and keep in sync with the content of the video playback. The general way is all to make subtitle template in advance,...
