Problems solved by technology

[0074] However, if file transfers are performed frequently, the file access and control of each processing circuit will conflict with each other, which may cause delays in file transfers, file loss, or control delays, thereby reducing the reliability of system control
[0075] Also, even if there is no doubt that the XML file 11 and the font file 12 can also be transferred to the working memory in the subtitle processor, interpreting subtitle data to extract information is very difficult for a subtitle processor implemented by a processor capable of integrating operations. is a burden

Abstract

In order to generate subtitles in a digital cinema projection system, the key is to reduce the burden of processing subtitles when showing a movie. Provided is a subtitle generating device for a digital movie projection system, comprising: a storage unit for storing movie subtitle files; a controller for generating internal files according to the subtitle files; and a subtitle processor for decoding internal files used to generate subtitles file and merge subtitles and movie frames with each other, wherein the subtitle file includes a main file, one or more font files including font data about text data, and one or more image files including image data described in the main file information identifying a text data file representing characters to be displayed as subtitles for a movie and an image data file representing image content to be displayed as subtitles for a movie together with control data for displaying subtitles, and a controller Generate an internal file from the subtitle file before displaying the movie.
