It should be noted that providing the ringing tone generating means 3 with a loudspeaker is preferable for a hands-free intercom. The intercom and the television interphone configured as described above operate as follows. The specific internal operation will be described with reference to the block diagram of FIG.

A portion surrounded by a broken line in the center of the figure is a representative example of the internal system of the main unit A of the intercom and the television interphone according to the present invention. First, when a visitor presses a call switch of a door phone slave unit with a camera (or a door phone slave unit) outside the entrance, the master unit A connected thereto and the sub master units A1, A2. The information is transmitted all at once and demultiplexed into image information and audio information.

For example, when the master unit A responds, the separated image information is subjected to FM video demodulation and is on-screened on a liquid crystal panel or the like. On the other hand, the separated voice information is sounded from the speaker, and the responder on the master device A side receiving the voice information talks with the visitor using the microphone. Next, when making an extension call, a plurality of individual call switches 2
Press switch 2 of the person you want to call from
The switch 2 selected by U is discriminated and designated, and the information of the discriminated switch is simultaneously transmitted to other sub-base units A1, A2, etc. through control and signal multiplexing. In addition, transmission to the intercom slave unit other than the extension call is not possible.

On the other side of the sub master units A1, A2,... Receiving the information of the designated switch, individual sounds and images are added to each of the designated switch information. The image is stored in advance as "Dad", the mother is a pop-up sound, the image is stored as "Mother" or the like in advance, the CPU determines the information of the specified switch, and an individual sound for this information is stored. Ringing the individual image on the speaker or television monitor 5 as the ringing tone generating means 3;
Is displayed.

The person identified by the individual sound and the individual display notices that the person is being called, takes nearby sub-masters A1, A2,... You can call directly. In the illustrated example, the case where the individual call switch 2 is operated by the base unit A has been described. However, the same function is performed even when any of the sub-base units A1, A2,. . [Third Embodiment] (Corresponding to Claims 6 and 7) By arbitrarily combining at least two or more of any of the above intercoms and television intercoms with one or more doorphone slave units or camera-equipped doorphone slave units, In response to a call from a door phone handset, etc., the intercom rings the visitor's ringing sound all at once, and when an extension call is made from any of the intercoms (master unit or sub master unit) using the individual call switch. In the case of other intercoms (secondary master unit or main unit), a ringing tone corresponding to the individual ringing switch is set in the case of the intercom, and the other party to be individually dialed together with the ringing tone is set in the case of the TV interphone. An intercom system or a video intercom system that outputs characters and pictures all at once is configured.

FIG. 4 illustrates a TV interphone communication system as an example. Here, two intercom units with camera, one master unit A and five subsidiary master units A
1 to A5 are illustrated. Note that the number 2 in the figure means two lines.

[0017] Such a system is nowadays used for two-family dwelling units or the like by connecting two or more camera intercom units or door intercom units to two or more groups of TV intercoms or intercoms, and providing one intercom with camera. It is assumed that a system is designed so that two or more groups of TV intercoms or intercoms can be selectively called from a slave unit or a door phone slave unit, or a TV intercom or intercom of another group can be called from one group.

For example, the master unit A and the sub master units A1 and A2 are installed in the home of the parent household, and the sub master units A3 to A6 are installed in the residences of the child households and connected in parallel. It is conceivable to install a door phone with camera connected serially outside the entrance of each household. When the visitor operates one of the slave units, the master unit A and the auxiliary master units A1 to A5 are sounded all at once. Then, the person who responds with one of the base units calls the extension as described above, and the individual sound and the individual image are sounded and displayed on the other main unit A and the sub-base units A1 to A5 in response to the individual call. As a result, the called person can respond smoothly and reliably to the nearby base unit A or the like.
