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： Transmitter 2 includes inverse multicarrier transformer 23 and D/A converter 24. Inverse multicarrier transformer 23 generates a notch by masking a carrier at a frequency location predetermined in accordance with a communication method of the transmitter. D/A converter 24 performs a D/A conversion on a transmission signal containing the notch and transmits the signal to a transmission line. Receiver 1 includes power measurement unit 171, comparator 172 and coexistence signal determination unit 173. Power measurement unit 171 measures a power value of a signal input from the transmission line. Comparator 172 determines whether or not the notch exits by comparing the measured power value with a threshold. Coexistence method determination unit 173 determines the type of coexistence method, based on the location of the detected notch.
