METHOD AND A SYSTEM FOR REGENERATING DIGITAL DATA IN AN OPTICAL INFORMATION STORAGE MEDIUM SUCH AS AN OPTICAL DISK

摘要

PURPOSE: A digital data regeneration method and a system thereof are provided to regenerate data smoothly though there occurs an error at a time stamp displaying a regeneration time of packet data. CONSTITUTION: The system comprises a time stamp controller(120), a data decoder(150), and a front end controller(130). The time stamp controller(120) checks whether a time stamp value of a current packet is effective in a case that the current packet is included in a data error area, outputs the current packet according to the time stamp value if the time stamp value is effective, and outputs the current packet according to an estimated time stamp value if not effective. The data decoder(150) decodes the received packet and regenerates the data included in the packet. The front end controller(130) corrects the error in the data extracted from data storage according to an error correction symbol and transmits the corrected data to the time stamp controller.
