摘要： A communication apparatus which transmits data to another communication apparatus through a transmission channel, includes: a display which displays a plurality of communication rates; and a controller which permits the display to display the communication rates. The controller acquires a first communication rate received from the another communication apparatus and based on a predetermined signal transmitted to the another communication apparatus through the transmission channel at a first time. The controller acquires a second communication rate received from the another communication apparatus and based on a predetermined signal transmitted to the another communication apparatus through the transmission channel at a second time. The controller calculates a plurality of communication rates on the basis of the first and second communication rate. The controller permits the display to display the plurality of the communication rate when a difference between the plurality of communication rates is larger than a predetermined value.

摘要： A power line communication apparatus transmits a signal to a first power line communication apparatus through a power line connecting to a second power line communication apparatus. The power line communication apparatus includes an information retriever for retrieving transmission rate information indicating both a first transmission rate and second transmission rate. The first transmission rate correspond to a first path of the power line along which the signal is directly transmitted to the first power line communication apparatus, and the second transmission rate corresponds to a second path of the power line along which the signal is transmitted through the second power line communication apparatus to the first power line communication apparatus. A selector selects, based on the transmission rate information, a path corresponding to a higher transmission rate among the first and second paths. A transmitter transmits the signal through the selected path.

摘要： PLC modems and a PLC communication system that includes the PLC modems receive a multicast packet from a video server of a multicast group. When a MAC address table is set therein, the PLC modems and the PLC communication system convert the multicast packet into a unicast packet and transmit the converted packet to a power line. When no MAC address is set, the PLC modems and the PLC communication system transmit the multicast packet to the power line.

摘要： A power line communication apparatus controls a transmission using a plurality of parameters. The power line communication apparatus includes: a registration processor which performs a registration process for achieving a state to be communicable with another power line communication apparatus through a power line by use of transmission data based on a first parameter set at a first value and a second parameter set at a second value, a parameter controller which changes the first parameter to the third value to lengthen a communicable distance and the second parameter to the fourth value to shorten the communicable distance when the registration process has ended in failure. When the registration process has ended in failure, the registration processor retry the registration process by use of transmission data based on the first parameter set at a third value and the second parameter set at a fourth value.
