Optical recording medium, apparatus and method for playing the optical recording medium

Abstract

An optical recording medium includes a start position of a caption and a marking at specific areas of contents. An apparatus and a method of playing the optical recording medium includes displaying a normal caption by moving an optical head of the apparatus to the start position of an effective caption and decoding from the start position while playing the contents. That is, the method of playing the optical recording medium includes analyzing a stream read out from the optical recording medium and detecting whether an identification code and information about the start position of the caption is recorded on a preliminary area of the stream, transferring to the start position of the caption recorded on the preliminary area by using the result of the detecting, and performing a signal process operation from the start position, so as to display the caption on a corresponding image of the optical recording medium being played back. Accordingly, a controller of the apparatus starts operating from the start position of the effective caption stored in a specific area to decode and display the effective caption, so as to normally display the caption while playing the optical recording medium.
