<p>PROBLEM TO BE SOLVED: To easily recognize the connection form of the flow of video signals and audio signals by visualizing the input/output conditions of the video signals and/or the audio signals between connected AV equipments and displaying the connection state of the flow. SOLUTION: In this AV system composed of the plural AV equipments and a display device connected to the AV equipments, the number of the connection of the AV equipments connected at present and a logical address chart for controlling the respective AV equipments are prepared in the RAM 17 of a control circuit 11. Then, to the respective AV equipments, the kind of the AV equipments, what kind of signals are outputted to which channel at present and which is the logical address of the AV equipment of the output destination are inquired and the table of the connection form is prepared on the RAM 17. Then, by using the logical address chart of the respective equipments and a signal input/output table, the connected AV equipments and the connection state of the flow of the audio signals and the video signals are plotted on a screen by a GUT.</p> |
