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.
