    • PURPOSE: An information storage device, an information processing device thereof, an information processing system thereof, an information processing method thereof, and a program thereof are provided to prevent the use of applied contents by using withdrawal information in a new version. CONSTITUTION: A storage unit(120) stores withdrawal information which is a list of an identifier of an unauthorized device. A data processor(110) extracts version information from the withdrawal information to transmit the extracted version information to a communication target device. When withdrawal information in a new version of issue order maintained by the communication target device is received from the communication target device, the data processor changes the withdrawal information in an old version stored in the storage unit to the new withdrawal information in order to store the new withdrawal information.

    • An information processing apparatus, a download method, a download interruption method, a download resuming method and a program are provided to resume the download of interrupted contents based on resumption information stored in a removable recording medium when the contents are recorded in the removable recording medium such that a plurality of information processors or a plurality of applications share the resumption information and interrupt and resume the download of contents. An information processing apparatus(20) includes a download unit(22), an interrupt processor(23) and a resumption processor(24). The download unit receives contents to be downloaded from a contents server(30) and records the received contents in a recording medium(7). The interrupt processor records resumption information required to resume download of the contents in the recording medium when receiving of the contents from the contents server is interrupted. The resumption processor reads the resumption information from the recording medium when receiving of the interrupted contents is resumed and requests the contents server to transmit the contents based on the read resumption information.
    • 提供信息处理装置,下载方法,下载中断方法,下载恢复方法和程序,以便当将内容记录在可移动记录介质中时,基于存储在可移动记录介质中的恢复信息恢复中断内容的下载 使得多个信息处理器或多个应用共享恢复信息并中断并恢复内容的下载。 信息处理装置(20)包括下载单元(22),中断处理器(23)和恢复处理器(24)。 下载单元从内容服务器(30)接收要下载的内容,并将所接收的内容记录在记录介质(7)中。 当从内容服务器接收到内容时,中断处理器记录在记录介质中恢复下载内容所需的恢复信息被中断。 恢复处理器在接收到中断的内容的恢复时从记录介质读取恢复信息,并且根据所读取的恢复信息请求内容服务器发送内容。
