When individually transmitting an image message from the manager's office unit 2 to a certain living unit, the image message sending personal computer 21 sends a signal indicating the image message and the identification code signal f ₂ of the individual identification code CB to the living units 4a, 4b ,.
Sent to

When a message is simultaneously sent from the manager's office unit 2 to the room units 4a, 4b, ..., The image message sending personal computer 21 sends a signal indicating the image message and the identification code signal f ₂ of the simultaneous identification code CA to the room units. 4a, 4b,
Sent to ... When a visitor calls, for example, the living room unit 4a from the camera-equipped collective entrance machine 1 and inputs the room number of the living room machine 4a from the camera-equipped collective entrance machine 1 and calls, the TV signal changeover switch of the management room machine 2 A television signal f _3, which is an image captured from the camera-equipped collective entrance machine 1, is sent to 23. Further, since the camera-equipped collective entrance machine 1 is linked with the image message sending personal computer 21, the signal for calling from the image message sending personal computer 21 and the identification code signal f ₂ of the individual identification code CB corresponding to the living room unit 4a are superimposed. It is sent to the circuit 24 and the identification code signal f ₂ of the individual identification code CB is supplied during the blanking period of the television signal f _3.
Are superposed by the superposing circuit 24. The television signal f ₃ on which the identification code signal f ₂ is superimposed is transmitted from the RF modulator 25 on a specific channel and mixed with the television co-listening system 3. (Ordinarily, the room units 4a, 4b, ... Receive general television broadcasts from the television co-listening system 3 on the television receiver 45.) The television signal f ₃ from the RF modulator 25 transmitted on a specific channel is , The television co-listening system 3, and the room television terminal 41 of the room unit 4a, to the code identification circuit 42. In the code identification circuit 42, what signal is being sent by the signal superimposed on the television signal f ₃ (here, a signal indicating a call), the individual identification code CB and the identification code of the own station match. It is identified whether there is a match, and only when the identification codes match, the in-room master unit 43 is activated and a ringing tone is generated.
