Abstract

Between a first equipment and a second equipment connected to a predetermined bus line, it is arranged that data for setting, etc. on input selection in the first equipment is instructed from the second equipment in the form of command having a predetermined format through the bus line, thus allowing an independent remote control to be performed between the first equipment and the second equipment. Moreover, data on input selection in the first equipment is transmitted to the second equipment, so that, for example, the remote control of the input selection in the first equipment linking with the operation of the second equipment will be performed satisfactorily.

Claims

1. An equipment control method of performing the control between equipments connected through a predetermined bus line, wherein

when data outputted from a first equipment can be inputted by a second equipment, data on an output route change of that data from the first equipment is transmitted to the second equipment through the bus line;

and

wherein for the data on the output route change, at least two kinds of requests are prepared, a first request instructing the second equipment about input switching to the changed route and a second request not instructing about the input switching, but causing the second equipment to estimate only the route change.

2. An equipment control method according to claim 1, wherein the output route includes an output route other than the bus line.

3. A transmission apparatus capable of data transmission with other equipment connected through a predetermined bus line, comprising

a command producing section for producing a command of a predetermined format instructing other equipment connected through the bus line about an output route change, and

a sending section for sending out the command produced by the command producing section to the bus line;

wherein for the command on the output route change produced by the command producing section, a command instructing about input switching to the changed route and a command not instruction about the input switching, but deciding only the route change are prepared.

4. An transmission apparatus according to claim 3, wherein the output route indicated by the command produced by the command producing section includes an output route other than the bus line.

5. A medium in which a program for performing the control between equipments connected through a predetermined bus line, wherein

when data outputted from a first equipment can be inputted by a second equipment, the program comprises the step of causing data on a change of an output route of the data from the first equipment to be transmitted to the second equipment through the bus line;

and

wherein the processing on a change of the output route in the above step includes at least two kinds of requests, a request instructing the second equipment at least about input switching to the changed route, and another request not instructing the second equipment about input switching, but only causing the second equipment to estimate the change of route.

6. A medium according to claim 5, wherein the output route to be changed in the above step includes an output route other than the bus line.
