Caption handling system and method of Digital Versatile Disk player

PURPOSE: A device for processing a subtitle of a DVD(Digital Versatile Disk) player and a method therefor are provided to conveniently display various languages not included in a DVD in a subtitle. CONSTITUTION: A video signal input unit(10) inputs a video signal including closed caption data. A subtitle input and output unit(20) inputs and outputs subtitle data preliminarily made in a language of a designated nation according to the closed caption data. A signal analyzing unit(30) analyzes the video signal for extracting a horizontal synchronous signal and detects the closed caption data from the horizontal synchronous signal. An SRAM(Static Random Access Memory)(41) temporarily stores hexa values of the extracted closed caption data. A ROM(Read Only Memory)(42) stores a system program. A RAM(43) stores the subtitle data and various data. A timer(50) measures a time of playing a DVD. A control unit(60) compares the closed caption data stored in the SRAM with subtitle data stored in the RAM for outputting a subtitle signal in the case that synchronous signals coincide with each other. An output unit(70) outputs the subtitle signal to an external display device.
