20090207319 | Apparatus which converts remote control signal, remote controller, remote control apparatus, and remote control method - A remote-control-signal conversion apparatus is disclosed. The remote-control-signal conversion apparatus receives a radio control signal from a remote controller, converts the radio control signal into an infrared control signal, and transmits the infrared control signal to an external device. When the apparatus identifies the external device, the apparatus transmits a plurality of infrared control signals to the external device. The apparatus identifies device identification information of the external device based on a response from the external device. The apparatus radio transmits the identified device identification information to the remote controller. The apparatus transmits the device identification information and a control code corresponding thereto as the infrared control signal received from the remote controller to the external device. The apparatus transmits the infrared control signal to the external device. | 08-20-2009 |
20090219174 | Remote control method and remote control apparatus - A remote control method is disclosed. The remote control method is used for a device under control which selects one of an information signal of the device under control and an information signal from at least one external device and reproduces the selected information signal. | 09-03-2009 |
20100107029 | Wireless communication apparatus and wireless communication method - A wireless communication system includes a transmitting side equipped with a microcomputer for control, for transmitting data and also includes a receiving side for receiving data. To prevent the receiving side from receiving identical data more than once, a sequence number is automatically incremented every time a frame of transmit data is transmitted. The sequence number is transmitted together with the data. The next process is performed if it is determined that transmission is correctly performed, or the data is transmitted again without incrementing the sequence number if it is determined that the transmission is not correctly performed. The sequence number is returned to an initial value when the microcomputer for control is reset, and dummy data is transmitted together with the initial value immediately after a reset. The data is transmitted together with an incremented sequence number after transmission of the dummy data. | 04-29-2010 |
