DRM METHOD USING BAD PATTERN, AND DIGITAL CONTENTS RECORDER/PLAYER AND METHOD USING THAT

摘要

A digital copyright protection method, a digital contents registering method using the same and a digital content recording medium thereof are provided to provide an inherent DRM encryption table to each digital contents storing medium. A flash memory whole block sets up an area by a block multiplexing unit. A bad pattern extraction area is determined based on the bad block table. An area code value of the corresponding area is recorded in the DRM table selection code field of the card ID. The determined bad pattern extraction area is tested(401). A checking target area includes the bad block DRM table of 256 byte.
