Problems solved by technology

In this way, the cost of the known closed caption playback system is increased, making it impossible for users to use the function of closed caption conveniently and universally
In addition, the known closed caption playback system cannot allow the user to decide the display mode of the closed caption (such as the font, color, position and size of the subtitle in the screen, etc.)
As mentioned above, in the media signal 26 provided by the access module 18, the closed caption signal 25B itself specifies the display mode of the closed caption, and the encoding module 20 encodes the relevant information of the closed caption according to the specified display mode. Invisible scan line data, which determines the actual display format of the closed caption, cannot be determined by the user
Furthermore, the user controls the playback of audio-visual multimedia signals through manipulation on the playback device side, but controls the display of closed captions through manipulation on the display side, which will also cause trouble for the user in manipulation.

Abstract

The present invention provides play system structured on a play device such as a hidden subtitling play system structured on optical media play device. To display state of display device, common device has function of information display. When a display device read media signal from storing media and output the video signal to a display, this invention analyzes the hidden subtitling signal of the media signal, extracts the letter signal from hidden subtitling signal, displays the character of hidden subtitling as the display's information; then it comes to purpose of displaying subtitling.

Description

technical field [0001] The present invention relates to a playback system based on a playback device, in particular to a closed caption playback system that utilizes the information display function of the playback device to display closed captions. Background technique [0002] In the modern information society, rich dynamic images and sounds can already be recorded as audio-visual multimedia data, and various information, knowledge, news, entertainment, etc. can be presented with colorful audio-visual effects. Audio-visual multimedia data can be stored in various optical, magnetic or electronic storage media, such as compact disc (CD, Compact Disc), digital versatile disc (DVD, Digital Versatile Disc), hard disk, electronic memory (such as random access memory) ) with flash and so on. When the stored audio-visual multimedia data is to be played out, an appropriate playback device can be used to read out the audio-visual multimedia data stored in the storage medium, conver...
