Description

  The present invention makes it possible to display subtitles that are not provided in the recorded disc on a playback image of an issued (existing) removable recording disc, particularly a Japanese DVD (audio is recorded in Japanese) by a hearing impaired person. In addition, the present invention relates to a subtitle display method for a reproduced image of a recorded recording disk suitable for viewing a DVD.

In recent years, discs (removable recording discs) on which removable image / audio data are recorded, particularly movies such as movies recorded on DVDs (including slide pictures, motion pictures, etc. in addition to ordinary moving images), so-called so-called works. The spread of DVD content is remarkable.
By the way, on a DVD on which a foreign movie is recorded, subtitles in a language other than the native language voice of the movie are recorded, such as Japanese, and reproduced and displayed together with the movie image. However, when the native language sound of the movie is Japanese, such as a domestic movie such as a Japanese movie, Japanese subtitles are generally not recorded and therefore not displayed.

For this reason, for example, a hearing-impaired person who uses Japanese, even if it is a DVD content issued in Japan (released, distributed, etc.) and whose native language is Japanese, is related to that image along with the display image. I couldn't appreciate the audio content such as conversation.
In addition, Japanese subtitles are not always recorded on DVDs created and recorded in foreign countries. In this case, both hearing-impaired and healthy people appreciate the audio content such as conversations related to the displayed images. I couldn't.
A DVD on which a work such as a movie is recorded is an issued medium (usually a ROM medium), so that Japanese subtitles are not added to the DVD after issuance. In addition, in view of the fact that the most DVDs published in Japan are Japanese works, the inability to appreciate the audio content of such Japanese DVDs is difficult for hearing impaired people who use Japanese. This is extremely inconvenient, and there has been a strong demand for improvement in this regard.

On the other hand, a technique called “real-time subtitles” has recently been developed. This is because a subtitle user prepares a television (hereinafter referred to as TV) and a personal computer (hereinafter referred to as PC), and the audio related to the TV image is transmitted to the personal computer using the Internet chat function. Subtitles are displayed on a display and displayed in real time (see Non-Patent Document 1).
