  • Publication number: 20080057936
    Abstract: According to one embodiment, there is provided an electronic apparatus adapted to execute wireless communication with another device. The apparatus includes a module that executes the wireless communication, and a driver that causes the module to execute a scan process for detecting a device existing around the electronic apparatus by broadcasting a probe request packet and receiving a probe response packet corresponding to the probe request packet, thereby generating a device list of detected devices. The module further receives a probe request packet broadcasted from a device other than the electronic apparatus during the scan process, and the driver acquires information included in the probe request packet and adds the device to the device list.

  • Publication number: 20080055148
    Abstract: According to one embodiment, an electronic device includes a controller which performs communications with a module, executes procedures for initializing the module in response to input of an insertion signal, and stops the communications with the module in response to input of an extraction signal, a power supply which applies a drive voltage to the module in response to input of a power-on command and stops applying the drive voltage to the module in response to input of a power-off command, command supplying section which supplies power-on command to the power supply when the user selects an “on” item and supplies the power-off command to the power supply when the user selects an “off” item, and signal supplying section which supplies the insertion signal to the controller when the user selects the “on” item supplies the extraction signal to the controller when the user selects the “off” item.

  • Patent number: 6826233
    Abstract: A data transmission apparatus for transmitting data comprising a plurality of objects having respective priority, comprises an error-correction coding section for selecting an error-correction coding method for each of the plurality of objects based on the priority of each of the plurality of objects and error-correction coding of each of the plurality of objects using the selected error-correction coding method. Therefore, it is possible to effectively use the resources, maintain the real-time transmission of data, and prevent degradation of transmitted data by changing the level of the error-correction according to the priority of object, and performing the error-correction coding for the objects according to the priority.

  • Publication number: 20030224778
    Abstract: Disclosed is a system for transmitting audio data from a transmitter to a receiver in radio data communication. On detecting a non-audio data area of a predetermined amount of data, a non-audio detection unit included in the transmitter notifies a communication control unit of the detection. The communication control unit disconnects the radio communication connection with the receiver for a period corresponding to the non-audio period (non-audio data area). When the non-audio data area disappears from the radio data, the communication control unit re-establishes the radio communication connection.
