WHEN INPUT EQUIPMENT IS INSTRUCTED BY A REMOTE CONTROL UNIT ON THE BASIS OF A DISPLAY OF A MONITOR, A DATA SIGNAL IS TRANSMITTED FROM A MICROCOMPUTER OF AN AV AMPLIFIER (20) TO A MICROCOMPUTER (21) OF A CD CHANGER (30). WHEN THE SIGNAL IS RECEIVED BY A MICROCOMPUTER (31) OF THE CD CHANGER (30), DISPLAY DATA IS FORMED IN THE MICROCOMPUTER (31) OF THE CD CHANGER (30) ON THE BASIS OF DATA IN A MEMORY AND IS OUTPUTTED. IN THE AV AMPLIFIER (20), A SWITCH IS SWITCHED TO THE CD CHANGER SIDE. A CURSOR IS FORMED BY THE MICROCOMPUTER (21) OF THE AV AMPLIFIER (20), THE CURSOR AND DISPLAY DATA FROM THE CD CHANGER (30) ARE SYNTHESIZED BY AN IMAGE SYNTHESIZING CIRCUIT (22) AND DISPLAYED ON THE MONITOR (40). WHEN AN INSTRUCTION IS GENERATED BY THE REMOTE CONTROL UNIT ON THE BASIS OF THE DISPLAY ON THE MONITOR (40), POSITION COORDINATES OF THE CURSOR ON THE PICTURE PLANE ARE GENERATED FROM THE MICROCOMPUTER (21) OF THE A/V AMPLIFIER (20) TO THEMICROCOMPUTER (31) OF THE CD CHANGER (30). ON THE BASIS OF THE DISPLAY DATA AND THE POSITION COORDINATES, THE CD CHANGER (30) IS CONTROLLED BY ITS MICROCOMPUTER (31). WHEN A PREDETERMINED POSITION ON THE PICTURE PLANE IS INSTRUCTED BY THE REMOTE CONTROL UNIT, THE CONTROL IS RETURNED TO THE AV AMPLIFIER (20) . |
