A communications system connected via a bus capable of transferring combinations of control signals and AV signals as packets while providing an environment which is the same as an environment where connections are made using analog signal lines. A register decided by an address is taken to be a virtual plug for each item of equipment. The plug enable for the input plug is set to 1 and a synchronous communication packet for the AV signal from the channel set by the channel number is received. The plug enable for the output plug is set to one and the synchronous communication packet for the information signal is sent to the channel set by the channel number at a transmission speed designated by the DR (Data Rate) at the bandwidth expressed by “Bandwidth”.
A communications system with a plurality of items of equipment having input/output plugs and/or containing one or more functional units, connected via a bus, capable of transferring packets containing combinations of control signals and information signals, wherein the input/output plugs for the items of equipment within the system are given attributes and handled in the same way as the functional units within the items of equipment.
A communications system with a plurality of items of equipment, connected via a bus, capable of transferring packets containing combinations of control signals and information signals, wherein virtual plugs for inputting and outputting information signals are set up at each of the items of equipment within the system and information signal connections between each of the items of equipment are made by controlling connections between the plugs.
An information signal control apparatus capable of transferring packets containing combinations of control signals and information signals, wherein input/output plugs for items of equipment within the system are allotted attributes and handled in the same way as functional units within the items of equipment.
An information signal control apparatus capable of transferring packets containing combinations of control signals and information signals, wherein, when a plurality of the information signal control apparatus are connected together to make a communications system, virtual plugs for inputting and outputting information signals between each item of equipment within the communications system are set up and information signal connection is carried out between each item of equipment by controlling connections between the virtual plugs.
