    摘要: A Smart card-based service providing system and method, in which a service application uses resources of a common application and which can easily cope with an addition of a service application into the Smart card and thereby efficiently utilize valuable resources of the Smart card, is provided. A management application specially designed for access control is installed in the Smart card to solely manage access management information. A management of or a decision on an access right is not performed by the service application or the common application but by the management application. When a new application is added to the Smart card, the service provider device receives a permission to update access management information beforehand from the card issuer device and, based on the permission, updates the access management information.

    摘要: A control unit for controlling a modem used in a receiver demodulates a received signal by use of an adaptive equalizer, and a recovery circuit includes a timing recovery function and a carrier recovery function. States regarding operations in the adaptive equalizer and the recovery circuit are updated based on the received signal. The modem includes a determination unit for determining whether or not the modem is operating unusually based on a signal processed in the modem, a buffer for storing state data at a predetermined timing when the determination unit determines that the modem is not operating unusually, and a controller for controlling the adaptive equalizer and the recovery circuit so that the adaptive equalizer and the recovery circuit operate based on the state data which has been stored in the buffer when the determination unit determines that the modem is operating unusually.
