摘要： Each embodiment of this invention implements step-by-step and empirical authentication of devices upon digital authentication among a plurality of devices. Each of a plurality of authentication devices of each embodiment can unidirectionally generate a hash value of a low experience rank from a hash value of a high experience rank, and receives a set of high experience rank and hash value in accordance with an experience. Upon receiving a certification request of the experience rank from another authentication device, the authentication device transmits a corresponding hash value to the authentication device as a request source. Upon sending a certification request of an experience rank to another authentication device, the authentication device verifies a hash value obtained from the other authentication device on the basis of a self hash value. In this way, the authentication devices authenticate each other's experience ranks.

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.

摘要： According to a data display method, data having a program unit and instruction data for the program unit multiplexed on bit stream data is received. The program unit is extracted from the received data and is stored in a memory. The instruction data is extracted from the received data, and the program unit or part thereof specified by the instruction data is read from the memory and is executed. Then, the bit stream data and the execution result are displayed. This ensures smooth synchronization of reproduction of a bit stream with execution of an associated program and efficient use of resources.
