    Abstract: A list of video fingerprinting data that represents a feature of the newest video content is extracted from a digital video disc 160 or provided by a copyright supervisor authorized by a managing organization. The list of the video fingerprinting data is recorded in a non-volatile memory 181. When video content is reproduced from the digital video disc 160, a fingerprinting data calculating portion 187 extracts the feature of the video content and obtains video fingerprinting data. When the data is contained in the list, the reproduction for the video content is restricted. Thus, the reproduction for an illegal digital video disc 160 can be restricted until the copyright supervisor permits the reproduction for the digital video disc 160.
