摘要： A terminal device determines whether a clock is a secure clock or a self-running clock. If the clock is the self-running clock, the device stores a clocking time of the clock as a timestamp file in a memory card in recording content. In playing back the content, the device determines validity of a clocking time using the timestamp file to play back the content and also updates the stored time of the stored time as the timestamp file to a content playback start time. In contrast, if the clock is the secure clock, the device stores the timestamp file indicating a recording time of the content in the memory card only in recording the content and omits updating the stored time as the timestamp file in playing back the content.
摘要翻译：终端设备确定时钟是安全时钟还是自运行时钟。如果时钟是自行运行的时钟，则在记录内容时，设备将时钟的时钟时间作为时间戳文件存储在存储卡中。在回放内容时，设备使用时间戳文件来确定时钟时间的有效性来播放内容，并且将存储的时间作为时间戳文件更新为内容播放开始时间。相比之下，如果时钟是安全时钟，则设备仅在记录内容时将指示内容的记录时间的时间戳文件存储在存储卡中，并且在回放内容时省略更新存储的时间作为时间戳文件。

摘要： In a first terminal serving as rights assignment source, an encoding binding state of a key encoding key included in a rights object is converted from a bind using a binding key of the first terminal and a bind using a domain key. Then, the rights object including the thus bound converted key encoding key is transferred to a second terminal serving as rights assignment destination together with encoded contents, and further, the above domain key is transferred to the second terminal via a secure session.

摘要： A download control program of a client terminal transmits a request to a download server, which stores Download Descriptors that include attribution information of contents, for a Download Descriptor, and receives the Download Descriptor from the download server. The download server, before transmitting the Download Descriptor to the client terminal, adds information indicating that there is a difference between a Download Descriptor contained in the request from the client terminal and the Download Descriptor stored in data memory of the download server if the download server detects the difference between them. The client terminal transmits a content download request to a contents server based on the received Download Descriptor.
