Abstract: A reception device includes a wireless communicator, a memory, and one or more processors. The processors identify a retransmission candidate of image data on the basis of a sequence number recorded on the memory. The processors calculate an upper limit retransmission number on the basis of a physical rate and a communication rate recorded on the memory. The processors set an allowable retransmission number that is less than or equal to the upper limit retransmission number. The processors transmit a retransmission request for requesting retransmission of as many of the retransmission candidates as the allowable retransmission number to the transmission device in a blanking period by using the wireless communicator when the number of the retransmission candidates identified through the identification processing exceeds the allowable retransmission number.

Abstract: In a wireless communication terminal, a control circuit is configured to cause a wireless communicator to wirelessly connect to a first AP on the basis of authentication information of the first AP stored on a memory and is configured to execute authentication processing with the first AP on the basis of the authentication information of the first AP stored on the memory without executing setup processing when the control circuit selects a first mode. The control circuit is configured to start the setup processing with a second AP by using the wireless communicator when the control circuit selects the second mode. The control circuit is configured to cause the wireless communicator to wirelessly connect to the second AP and is configured to execute the authentication processing with the second AP on the basis of authentication information received from the second AP by the wireless communicator.

Abstract: A wireless communication terminal has a plurality of communicators, a radar detection circuit, a channel use confirmation circuit, a channel information acquisition circuit, a channel information notification circuit, a channel determination circuit, and a channel setting circuit. First communication channel information indicates a data communication channel set in a communicator of a first peripheral terminal. Second communication channel information indicates a monitoring communication channel set in the communicator of the first peripheral terminal or a communication channel confirmed to be usable by the channel use confirmation circuit of the first peripheral terminal. The channel determination circuit determines a communication channel different from any of a first communication channel indicated by the first communication channel information and a second communication channel indicated by the second communication channel information as the data communication channel.

Abstract: A controller of a wireless communication terminal wirelessly receives second communication channel information from a second wireless communication terminal using a communicator. The controller wirelessly transmits first communication channel information and the second communication channel information to a third wireless communication terminal using the communicator. The controller wirelessly receives third communication channel information from the third wireless communication terminal using the communicator. The controller wirelessly transmits the first communication channel information and the third communication channel information to the second wireless communication terminal using the communicator.

Abstract: A received image displaying apparatus comprises: a wireless communication unit that wirelessly receives the frame images transmitted by the image transmitting apparatus with which the received image displaying apparatus has established a connection of wireless communication; and a displaying unit that displays the frame images, which were wirelessly received by the wireless communication unit, in an order in which the frame images were captured. At least one of the image transmitting apparatus and the received image displaying apparatus comprises: a reference sync signal generating unit that generates the reference sync signals; and a control unit that, if the wireless communication unit has received no reference sync signals for a certain time interval, controls the reference sync signal generating unit to generate reference sync signals and that further controls the wireless communication unit to wirelessly transmit the reference sync signals to the other apparatus included in the image transmitting/receiving system.

Abstract: A first communicator of a first communication device is configured to use a first wireless channel and execute first key-exchange processing at a timing at which a first key-exchange timer expires. A second communicator of the first communication device is configured to use a second wireless channel and execute second key-exchange processing at a timing at which a second key-exchange timer expires. When streaming data are transmitted by using one wireless channel of the first wireless channel and the second wireless channel and a difference between a first key-exchange timer value and a second key-exchange timer value is greater than a predetermined range, a control circuit is configured to change a wireless channel used for transmission to the other wireless channel before key-exchange processing in the one wireless channel is started.

Abstract: An image transmission system, has an imaging terminal configured to transmit image data at a cycle of imaging timing; and a display terminal configured to receive the image data and display the image data at a cycle of display timing. The image transmission system has functions of calculating communication delay time, estimating accuracy after adjusting a cycle of the imaging timing or the display timing, determining whether to perform an adjustment of the imaging timing or the display timing, and performing the adjustment of the imaging timing or the display timing which are included in either of the imaging terminal or the display terminal. The image transmission system further has a function of assisting the calculation of the communication delay time which is included in the other of the imaging terminal or the display terminal.
