摘要： The present invention relates to an encoding and recording apparatus, a playback apparatus, and a program which solve the possibility of a capacity shortage of a protected area accompanying an increase in an information amount and the number of content keys. It is configured such that an encoded user identifier is recorded in a protected area of a key storage medium. The encoded user identifier is fixed information, and has the characteristic in which a data amount is not increased in connection with a utilization form. Therefore, a capacity shortage of the protected area is not brought about.

摘要： An interface control device includes a first interface, a second interface, a third interface, an interface controller and a clock supplying unit. The first interface is used to communicate with a first information processing device and obtain a first clock signal from the first information processing device. The second interface is used to communicate using a second clock signal with a second information processing device different from the first information processing device. The third interface is used to communicate with a controller of a data-storage medium. The interface controller performs an interface control for the first, second and third interfaces. Moreover, the clock supplying unit supplies the first clock signal to the third interface while communications through the second interface have not been established.

摘要： An apparatus determines whether a combination of a certificate type of a content certificate recorded on a source recording medium and a medium type of the source recording medium is a proper combination. If the combination is a proper combination, the apparatus requests a license server, which is connected to the apparatus via a network, to give approval to record content on a target recording medium. If the apparatus is a legitimate DVD recorder, the license server sends to the content recording apparatus a content certificate including on the source recording medium as the certificate type. The apparatus records the content together with the received content certificate on the target recording medium.
