    • Managing the use of an optical disc drive by a program at high security. An OS of a host apparatus 100 sends one user certificate incorporating the policy information defining the use contents permissible for the optical disc drive 200 and a user key to the optical disc drive 200 under a secure environment (S3). On the other hand, the program running on the OS is authorized, and the user key is passed to the authorized program (S6). The optical disc drive 200 authorizes the program using the user key within the user certificate and the user key for the program and specifies the policy information corresponding to the user key (S7). Thereafter, the optical disc drive 200 permits the application program to gain access to the self-resource within the limits of the contents defined in the policy information (S8).
    • 通过高安全性的程序管理光盘驱动器的使用。 在安全环境下,主机设备100的操作系统将一个将光盘驱动器200允许的使用内容和用户密钥的策略信息合并到一个光盘驱动器200中的用户证书(S3)。 另一方面,在OS上运行的程序被授权,并且用户密钥被传递到授权程序(S6)。 光盘驱动器200使用用户证书内的用户密钥和程序的用户密钥授权程序,并指定与用户密钥相对应的策略信息(S7)。 此后,光盘驱动器200允许应用程序在策略信息中定义的内容的限制内访问自身资源(S8)。

    • A plurality of copies of an information signal are prevented from being formed. For example, a transmitter such as IRD, STB, or the like transmits an information signal supplied from the outside via a radio wave or the like to each apparatus in a system. Together with a monitor, a speaker, and the like, for example, two recorders such as VTRs or the like are provided in the system. It is assumed that the recorder is executing the recording operation. The transmitter recognizes that the recorder is under the recording operation. Even if the other recorder issues a request indicating that it wants to perform the recording operation in this situation, the operation responsive to the request is not permitted. By such a management, a plurality of recorders in the network are prevented from recording the same information signal. A plurality of copies are prevented from being formed with respect to the same information signal.
    • 防止形成信息信号的多个副本。 例如,诸如IRD,STB等的发送器通过无线电波等将从外部提供的信息信号发送到系统中的每个设备。 与监视器,扬声器等一起,例如在系统中提供诸如VTR之类的两个记录器。 假设记录器正在执行记录操作。 发射机识别录音机处于录音操作状态。 即使其他记录器在这种情况下发出指示要执行记录操作的请求,也不允许响应该请求的操作。 通过这种管理,防止网络中的多个记录器记录相同的信息信号。 防止相对于相同的信息信号形成多个副本。
