Description

  The present invention relates to a caption display system, and more particularly, to a caption display system using a display unit that displays caption data synchronized with a video, which is individually worn and used by a candidate in a movie theater or a 3D theater. .

  There are several important issues that are not currently addressed in movie theaters and 3D theaters. One is the problem of hearing impaired people.

  Deaf people include those who cannot hear at all, and those who cannot obtain information by voice due to deafness, etc. And 3D movies are not being produced.

  Therefore, the hearing-impaired person has to wait for the appearance of a movie video with subtitles of conversation at the bottom. Needless to say, the subtitles correspond to all the conversations in the movie in real time.

  However, this subtitle is often added in the case of a foreign movie, but when a Japanese movie is released as a video, the subtitle is not usually added. Accordingly, hearing impaired persons are not only far from the open movie theaters and 3D theaters, but also cannot enjoy Japanese movies and 3D movies at home.

  A possible solution is that when someone else is listening to the conversation, the deaf person can read the subtitles about the conversation and project it on the screen in the same way as a subtitle display in a normal foreign movie. For example, subtitles may be inserted into the film to be played, or subtitles may be directly projected onto the screen by an auxiliary projector.

However, when subtitles are added to Japanese movies in this way, it is very disturbing for the normal hearing listeners who make up the majority, and it is generally not possible to broadcast two types of Japanese movies with and without subtitles. There is a profitable problem.
