Abstract
Abstract A communications system comprises items of equipment 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. A plug enable for an 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. A plug enable for an 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".

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
66 words
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.
Claim 2
Dependent Claim
26 words
A communications system according to claim 1, wherein the input and output plugs only input and output information signals and are not connected to the bus.
Claim 3
Dependent Claim
15 words
A communications system according to claim 1, wherein the input output plugs are bus channels.
Claim 4
Dependent Claim
67 words
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.
Claim 5
Dependent Claim
19 words
A communications system according to claim 4, wherein the virtual plugs are set up separately for inputting and outputting.
Claim 6
Dependent Claim
50 words
A communications system according to claim 4, wherein connections made between the items of equipment using virtual plugs and connections made between functional units for inputting and outputting information signals within the items of equipment and virtual plugs for the items of equipment are carried out independently from each other.
