RECORDING MEDIUM AND PRODUCTION METHOD, PLAYBACK METHOD, AND PLAYBACK DEVICE THEREOF

摘要

A list of video fingerprinting data is recorded in a nonvolatile memory (181). The video printing data is created by extracting the features of the latest video content provided on a digital video disc (160) or provided by a copyright management server authorized by a management organization (120). When a video content recorded on the digital video disc (160) are played back, the features are extracted in calculation (187) of fingerprinting data to obtain video fingerprinting data. If the data is included in the list, the playback is restricted in order to restrict unauthorized playback of the digital video disk (160) until the copyright manager permits.
