Abstract

An apparatus for controlling addresses of symbol data obtained by demodulating a bit stream read from a disk for an error correction is provided. The apparatus for controlling the addresses of the symbol data includes, a sync detector for receiving the bit stream and detecting a frame sync and an ID sync, a frame sync number generator for receiving the frame sync, comparing the frame sync with a sync frame structure, correcting the frame sync, and generating information on the position of the frame sync, an ID error corrector for correcting the errors of the ID included in the symbol data and outputting the ID, an ID sync number detector for receiving the ID and a frame sync from the sync detector and detecting the information on the position of the ID, an address generator for receiving the information on the position of the frame and the information of the position of the ID, and generating the address of the symbol data corresponding to an ECC block, and a controller for controlling the detectors and the generators. It is possible to effectively perform the error correction by generating a memory address according to the sector and the frame set by the information of the position of each frame and information on the position of the ID with respect to the symbol data read from the disk of a DVD player and then demodulated and storing the symbol data in a memory precisely corresponding to the ECC block.
