Abstract
Official abstract text for this publication.
Unique identification information is prerecorded on a disc. The identification information is registered to a server along with user's license when he or she buys the disc. When an terminal unit reproduces data from the disc, identification information is read and transmitted to the server through the Internet. The server creates a key that controls to reproduce data from the disc in accordance with the license identified by the identification information and transmits the key to the terminal unit along with the user's license information for the disc. The terminal unit controls to reproduce contents of the disc in accordance with key and license information transmitted from the server. The license for each disc is managed in accordance with the identification information. Thus, different services can be provided for individual discs.
