Subtitle broadcasting system with software previewing function

Abstract

The invention provides a subtitle broadcasting system with a software previewing function, which comprises a network application terminal and a plurality of subtitle generators. The network application terminal comprises a material transmission unit, a command transmission unit, a subtitle receiving unit and a software previewing unit, wherein the material transmission unit is used for sending material information in different languages to the subtitle generators; the command transmission unit is used for sending a rendering command or a foldback command to the subtitle generators; the subtitle receiving unit is used for receiving subtitle pictures in different languages returned from the subtitle generators; and the software previewing unit is used for displaying the subtitle pictures in different languages returned from the subtitle generators on a plurality of software windows in a user interface, so as to preview the subtitle pictures. Each subtitle generator comprises a receiving unit, a subtitle rendering unit and a subtitle foldback unit, wherein each receiving unit is used for receiving commands and the material information in corresponding languages; each subtitle rendering unit is used for performing subtitle rendering processing to the material information; and each subtitle foldback unit is used for returning the rendered subtitle pictures in corresponding languages back to the network application terminal. The subtitle broadcasting system achieves the software previewing of subtitle broadcasting in different languages, saves the cost, and is convenient to operate.

Description

technical field [0001] The invention relates to the field of video and audio program production, in particular to a subtitle broadcasting system with software preview function. Background technique [0002] With the rapid development of the radio and television industry, the broadcast forms of programs are gradually diversified, and the requirements for program production are getting higher and higher. The continuous development of video and multimedia technology has also promoted the rapid development of subtitle production, and the scope of subtitle production is extremely wide. Generally speaking, adding text, pictures, animations, special effects and other information to the original video can be done. Call it subtitling. [0003] The same program may be broadcast on multiple channels at the same time, and for different channels, subtitles in the corresponding language need to be superimposed on the program. The existing subtitle broadcasting mode is that for subtitles...

Problems solved by technology

This method needs to configure operators separately to control and monitor subtitles, which takes up a lot of human resources

[0004] In addition, because the subtitle machine is generally only used for subtitle processing, and does not have a strong user interface and display function, for subtitle monitoring, generally through two channels, one channel is connected to the hardware interface, in the hardware window (such as the display screen of the monitor) If there is no problem with the preview display, it will be triggered again, and the signal will be input to another channel to play the subtitles on the upper screen.

The traditional preview method needs to realize the output display of the subtitle screen through the board hardware, which has high requirements for the monitoring equipment. Some low-end subtitle systems do not have the hardware for this function, and the installation of specific monitors and display boards will cost a lot of money. bigger
