Abstract

This invention is a subtitle repeated play method in CD apparatus. If the language learner enters special single key, it can realize the simultaneously repeated play of subtitle data and corresponding video data and audio data in the DVD and other compact disc. It comprises the following phases: the first phase: reading the inserted CD; the second phase: when user enters some special single key during play, the subtitle data and corresponding video data and audio data will play repeatedly.

Description

(1) Technical field [0001] The present invention relates to a method for repeatedly playing subtitles in an optical disc device. A single key is set by a language learner to repeatedly play and output subtitles (Sub- Picture) data and the corresponding video data and audio data, thus making language learning easier for users. (2) Background technology [0002] Among the existing optical disc devices such as DVD playback devices, the main title (Main Title) video and audio data recorded on the high-density optical disc DVD are read, and the read signal processing becomes data image and audio signals, and then, through ordinary Connectors such as TVs output high-quality video and high-quality sound. [0003] In addition, multilingual subtitle data (Sub-picture data) can be added among the above-mentioned DVD, but, in order to make the above-mentioned subtitle data can be connected together with the above-mentioned corresponding main title video and audio data, and read and ou...
