Abstract: 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.

Abstract: A communication apparatus improves the throughput of a whole communication system while performing contention distributed control which provides equality of a transmission chance by observing a medium occupation state. The communication apparatus includes a back-off process section for performing, using a contention window, a regular back-off process which is performed at transmission of a transmission frame and a pseudo back-off process which is performed in a pseudo manner when the transmission frame is not transmitted. The communication apparatus also includes a medium information obtaining section for obtaining, by the pseudo back-off process, medium information indicative of a state of the transmission line medium when the transmission frame is not transmitted, and a medium state determination section for determining the state of the transmission line medium using the medium information to obtain determination information.

Abstract: A plurality of PLC adapters, such as a master 21 and slaves 22, are connected to a power line 11, which forms a PLC logic network 16. Electric apparatuses 48, such as a television monitor and a video recorder, are connected to the master 21 and the slaves 22 through repeaters 31. The master 21 is a control terminal having the function of QoS controller. The master 21 allocates timeslots for transmitting data over a network, acquires information on the actual data transmission rate detected by a data receiving terminal, and modifies the timeslot allocated to target data on the basis of the acquired information on the actual data transmission rate.
