摘要： A communication device includes a first receiver, a second receiver, a communication module, and a controller. The first receiver receives an operation signal from a remote controller. The second receiver receives a radio signal with a specific frequency. A power consumption of the second receiver is less than that of the first receiver. The communication module is capable of transmitting the operation signal to a first communication device. The controller controls power supply to the first receiver and the communication module and starts power supply to the first receiver and the communication module if the second receiver receives the radio signal. The communication module turns to a standby state if the first receiver does not receive the operation signal after start of power supply to the first receiver.

摘要： An interface control device includes a first interface, a second interface, a third interface, an interface controller and a clock supplying unit. The first interface is used to communicate with a first information processing device and obtain a first clock signal from the first information processing device. The second interface is used to communicate using a second clock signal with a second information processing device different from the first information processing device. The third interface is used to communicate with a controller of a data-storage medium. The interface controller performs an interface control for the first, second and third interfaces. Moreover, the clock supplying unit supplies the first clock signal to the third interface while communications through the second interface have not been established.

摘要： A wireless communication circuit includes a receiver to receive at least one of a beacon frame and a probe response frame from a first wireless communication apparatus belonging to a first communication group, at least one of the beacon frame and the probe response frame including first security information indicating a first encryption method. The circuit includes a transmitter to transmit an association request frame to the first wireless communication apparatus, the association request frame including second security information indicating a second encryption method which is supported by the wireless communication circuit, after a determination that the second encryption method overlaps with the first encryption method. The transmitter declines to associate with the first wireless communication apparatus if the first encryption method fails to overlap with the second encryption method. The transmitter transmits a data frame including a frame body after a reception of an association response frame.
