摘要： PROBLEM TO BE SOLVED: To reduce frequency of recording communication management information for taking measures against communication cut. SOLUTION: A digital contents distribution system includes a license server 101 for issuing licenses, a user terminal 103 for controlling the use of contents on the basis of the license issued, wherein the license server 101 decides it in accordance with the contents of the license to be issued whether or not the communication management information for taking the measures against the communication cuts has to be recorded, and notifies the user terminal of the decision. As a result, the user terminal 103 can reduce the frequency at which the communication management information is recorded. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem that it is not possible for the receiver of a transfer destination IC card to extend the term of validity of a license after transferring a license between IC cards in a communication distribution system. SOLUTION: When transferring a license between IC cards, the IC card of the transfer origin transmits the license movement notification of an EMM to an EMM server. In this case, a storage region corresponding to the transferred license in the IC card of the transfer origin becomes write-disabled. The EMM server which has received the license transfer notification prepares release information for releasing the write disabled status of the IC card of the transfer origin, and transmits it to the IC card of the transfer origin, and changes the sending destination of the EMM to the IC card of the transfer destination. The IC card of the transfer origin receives the release information from the EMM server, and transfers this to a write disabled status release information interpreting part. Then, the write disabled status release information interpreting part sets the release information in the storage region. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：为了解决转移目的地IC卡的接收者不可能在通信分配系统中的IC卡之间传输许可之后扩展许可证的有效期的问题。
解决方案：在IC卡之间传输许可证时，传输来源的IC卡将EMM的许可移动通知发送给EMM服务器。在这种情况下，与传送原件的IC卡中的传送的许可证对应的存储区域变为禁止写入。已经接收到许可证转发通知的EMM服务器准备用于释放传送源的IC卡的禁止写入状态的释放信息，并将其发送到传送源的IC卡，并将EMM的发送目的地改变为转移目的地的IC卡。传输来源的IC卡从EMM服务器接收释放信息，并将其传送到禁止写入的状态释放信息解释部分。然后，写入禁止状态释放信息解释部分设置存储区域中的释放信息。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To solve the problem of having difficulty in implementing in parallel a process that must be implemented in real time and a time-consuming process on a single-task device such as an IC card.
SOLUTION: An IC card 300 divides processes into a plurality of process blocks and retains the time required to process each of the process blocks. When causing the IC card 300 to implement the processes, a receiver 200 reports a time that the IC card can spend processing data to be processed not in real time. The IC card processes the process block that can be processed within the reported time. After the process, the IC card answers back to the receiver and then goes into a state that it can receive new requests. In this way the IC card 300 can process data to be processed in real time such as an ECM (Entitlement Control Message). When it is desired to continue an interrupted process, the receiver can continue the process of the data to be processed in real time by reporting to the IC card 300 that the process is continued.

摘要翻译：要解决的问题：为了解决在单任务设备（例如IC卡）上实时并且需要耗时的处理的并行实现难以实现的问题。解决方案：IC卡300将处理分成多个处理块并保留处理每个处理块所需的时间。当使IC卡300执行处理时，接收器200报告IC卡可以花费处理不是实时处理数据的时间。 IC卡处理在报告的时间内可以处理的过程块。在该过程之后，IC卡回答接收器，然后进入它可以接收新请求的状态。以这种方式，IC卡300可以处理诸如ECM（授权控制消息）等实时处理的数据。当希望继续中断的过程时，接收器可以通过向IC卡300报告该过程继续来实时地继续处理要处理的数据的处理。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a file distribution system that can attain bill charging in the unit of modules and in the unit of resources, brings efficiency to the transmission efficiency and relieves the load for receiver processing in the case of distributing file type contents by the data Carousel method. SOLUTION: A transmitter side executes encryption in the unit of files to configure a module. In the case of charging in the unit of modules, an ECM(Entitlement Control Message) is set to the DII(Download Information Indication) and in the case of charging in the unit of resources, the ECM is set to a resource list and data carousel is distributed. A receiver side acquires a DDB(Download Data Block) of the carousel, reconfigures the module and stores it to an HDD. When a user makes a view request, the receiver acquires the module on the HDD and charges according to the ECM set to the DII or the resource list.
