Abstract

Disclosed is a method for controlling a playback operation in an optical disc apparatus. According to a first embodiment of the invention, an optical disc apparatus has a database in which grades of a plurality of words is stored. The apparatus performs a counting operation to determine when the number of words read from the disk that exceed a predetermined word-grade exceeds a predetermined number. In this way the apparatus determines a viewer-grade of the disc according to the counted number. The apparatus then prevents the optical disc from being played when the viewer-grade of the disk is not appropriate, thereby preventing adolescents or children from being freely exposed to harmful programs. In another embodiment of the invention, an optical disc apparatus classifies words contained in subtitle / caption data read from an optical disc into groups on the basis of a difficulty grade of words. The apparatus then variably determines the number of playback times or a playback sequence for each word, and selectively and repeatedly reproduces individual words of the subtitle / caption data. This allows a user to gradually and repeatedly check words contained in one sentence on the basis of the difficulty grades, which results in greater convenience for the user to learn a foreign language.

Description

1. Technical field [0001] [1] The present invention relates to an optical disc device for reproducing data recorded on an optical disc such as a digital versatile disc (DVD). 2. Background technology [0002] [2] In general, an optical disc device (also referred to as an optical disc player) is adapted to reproduce data recorded in an optical disc such as a DVD disc or a high-density DVD (HD-DVD). With the development of data compression technology for compressing and transmitting video / audio data, the performance of optical disc devices has been greatly improved compared to before. [0003] [3] The optical disc used in the optical disc device records various data, for example, subtitle data in multiple languages, subtitle data or audio language data, so that the user can select his or her desired data from various data, and play selected data. [0004] [4] The disc may also contain audience rating information indicating the appropriate audience group, eg, adults, teens, o...
