Caption compiling and broadcasting system

Abstract

The invention provides a caption compiling and broadcasting system comprising a computer and a caption superimposing card; a caption broadcasting processing module is arranged in the computer; the caption broadcasting processing module comprises a simulation clock component; the simulation clock component comprises a time obtaining submodule, a time adjusting submodule, a pointer rotating submodule and a picture superimposing submodule, wherein the time obtaining submodule is used for obtaining the current time; the time adjusting submodule is used for adjusting the clock pointer according to the current time so that each pointer picture points to the position where the current time needs to point; the pointer rotating submodule is used for carrying out the rotation of corresponding angle for the adjusted time pointer picture according to preset time; and the picture superimposing submodule is used for superimposing the pointer picture in every rotation with the clock background base plate picture and outputting the combined pictures through the caption superimposing card. In the invention, the caption compiling and broadcasting system ensures the normal installation and operation and the normal manufacturing and broadcasting of the stimulation clock, thereby efficiently reducing the cost.

Description

technical field [0001] The invention relates to the technical field of video program production, in particular to a subtitle editing and broadcasting system. Background technique [0002] With the continuous development of video and multimedia technology, the subtitle editing and broadcasting system, as a special system for subtitle editing and broadcasting in TV program production, is becoming more and more popular in the field of TV program production, and the technical production indicators are also getting higher and higher.

Problems solved by technology

[0005] From the above description, it can be seen that one style of analog clock needs to store 133 pictures in the subtitle editing and broadcasting system. In practical applications, dozens or even more styles of analog clocks are generally required, and the amount of pictures required will be very large. , these pictures will occupy the space of hundreds of megabytes or even several gigabytes of the subtitle editing and broadcasting system, which will cause great difficulties to the installation and operation of the subtitle editing and broadcasting system. Its memory is obviously too consuming material and financial resources
