A communications system connected via a bus capable of transmitting multiplexed packets of control signals and AV signals while providing an environment, which is the same as an environment where connections are made using analog signal lines. A register with a fixed address is taken to be a virtual plug for each of a plurality of equipment. When the plug enable for the input plug is set to 1, an isochronous communication packet for the AV signal on the channel set by the channel number is received. When the plug enable for the output plug is set to one and the isochronous communication packet for the information signal is sent on the channel, then the channel number is set in the channel number field at a transmission speed designated by the DR (Data Rate) field at the bandwidth presented in the bandwidth field. |
