20080279562 | Transmitter, Receiver, Communication System, Communication Method, Communication Program - A communication system includes a transmitter and a receiver that establish mutual connections of a plurality of their communication layers for communication. The transmitter has a request generating part for generating a connection request including data and commands required to connect the plurality of adjacent communication layers, and a request transmitting part for transmitting the connection request to the receiver. The receiver has a request receiving part for receiving the connection request from the transmitter, and a connection establishing pant for extracting the data and commands from the connection request and establishing, based on the extracted data and commands, the connections of the communication layers. In this way, the time required for establishing the connections can be shortened. Thus, even if a data exchange is interrupted, a reconnection can be made in a short time to resume the data exchange. | 11-13-2008 |

20090136232 | INFRARED COMMUNICATION APPARATUS AND INFRARED COMMUNICATION METHOD - An infrared communication apparatus and method enabling data communication with a receiving device, regardless of a protocol with which the receiving device is compatible. A transmitting unit transmits a first packet to inquire whether a receiving device is compatible with a first protocol and transmits a second packet to inquire whether the receiving device is compatible with a second protocol, to the receiving device at least once, and transmits a plurality of third packets to inquire whether the receiving device is compatible with a third protocol, to the receiving device. A receiving unit receives a response packet indicating a protocol with which the receiving device is compatible, from the receiving device having received the first packet, the second packet, and the plurality of third packets. A data transmitting unit transmits data to the receiving device, based on the protocol indicated by the response packet received by the receiving unit. | 05-28-2009 |

20080279304 | DATA TRANSMITTING DEVICE, DATA TRANSMITTING METHOD, DATA TRANSMITTING AND RECEIVING SYSTEM, DATA TRANSMITTING COMPUTER PROGRAM AND STROAGE MEDIUM THEREFOR, DATA RECEIVING DEVICE, DATA RECEIVING METHOD, AND DATA RECEIVING COMPUTER PROGRAM AND STORAGE MEDIUM THEREFOR - A plurality of connection frames are transmitted which differ from each other in at least either modulation scheme or transfer rate. Accordingly, a receiving-end device can properly receive a connection frame even in an environment where the connection frame is likely to be affected by noise. | 11-13-2008 |
20080279561 | TRANSMITTING SYSTEM AND TRANSMITTING DEVICE - Protocol conversion based on a communication protocol and data modulation based on a communication method are performed, in advance, on desired transmission data by a host device, which is an external device. Then, the converted data will be written to a memory in a transmitting device. According to a transmission command from an input section, a logical device reads out the converted data stored in the memory, and then outputs the read data from a transmitting section. | 11-13-2008 |
20080311857 | Receiver, transmitter, communication system, method for controlling receiver, and communication method - A receiver establishes a communication between the receiver and a transmitter that transmits data by a directional wireless communication. While a connection request command which is information for requesting a connection is transmitted from the transmitter to the receiver at a predetermined period, a packet group corresponding to the connection request command is transmitted from the transmitter to the receiver. The receiver includes a receiver connection establishment control section which controls a communication device so that a connection between the transmitter and the receiver is established in accordance with the connection request command, in a case where the connection request information is received from the transmitter while the communication with the transmitter and the receiver is released. This allows the receiver to naturally reproduce streaming data with the use of a directional wireless communication. | 12-18-2008 |
20080313710 | COMMUNICATIONS DEVICE, COMMUNICATIONS METHOD, COMMUNICATIONS PROGRAM, AND COMPUTER-READABLE STORAGE MEDIUM STORING THE COMMUNICATIONS PROGRAM - The communications device of the present invention performs an authentication with the device at the other end automatically or through a simple operation, independently of an authentication scheme supported by the device at the other end. A communications device includes: a connecting section for establishing a connection with the other communications device according to the IrSimple scheme; an authentication section for performing an authentication by the IrSimple scheme; a connecting section for establishing a connection with the other communications device according to the IrDA scheme, an authentication section for performing an authentication according to the IrDA scheme; and a protocol switching section for causing the connecting section to initiate a connection and causing the authentication section to perform an authentication, when an authentication by the authentication section is unsuccessful. This makes it possible to switch to a protocol of the IrDA scheme and perform communications according to the IrDA scheme when the other communications device does not support device authentication of the IrSimple scheme although being compliant with the IrSimple scheme. | 12-18-2008 |
20090067854 | OPTICAL SPACE COMMUNICATION RECEPTION CIRCUIT, OPTICAL SPACE COMMUNICATION DEVICE, OPTICAL SPACE COMMUNICATION SYSTEM, AND ELECTRONIC DEVICE - An optical space communication reception circuit receives a signal in switched-over communication speed modes and under settings corresponding to the communication speed modes. Receiver sensitivity in the respective communication speed modes is set in advance such that maximum communicable distances in the communication speed modes are substantially equal. By this, it becomes possible, for example, in optical space transmission such as infrared communication and the like to enhance a false operation prevention characteristic against disturbance noise, without decreasing maximum communicable distances. | 03-12-2009 |
20090180394 | COMMUNICATIONS DEVICE, COMMUNICATIONS METHOD, AND STORAGE MEDIUM - A communications device is provided which receives data frames in FIR communications mode even if the device has failed to normally receive a connect frame in SIR communications mode. | 07-16-2009 |
