JPS63142943A - Television receiver with telephone set - Google Patents

Abstract

PURPOSE:To allow the viewer to watch the television receiver till the opposed party replies in making a call during television watching by detecting the operating state of the telephone set and displaying its operating state on a cathode ray tube. CONSTITUTION:In hooking off a handset (not shown) of a telephone set 6 to make a phone call, a dial tone detection circuit 7 detects a dial tone, an off- hook display circuit 12 is operated and a character display of 'OFF-HOOK' is applied to part of the cathode ray tube 5 through a TV/telephone set changeover circuit 4 in a form of a slave pattern. In making a dial, it is detected by a dial signal detection circuit 8, a dial display circuit 13 is operative and the character display of 'in dialing' is displayed similarly on the cathode ray tube 5. The character display of 'calling' in case of calling the opposite party, 'busy' in case of a busy state, and 'talking available' in case of the opposite party replies are displayed respectively on the cathode ray tube 5 similarly.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a telephone-equipped television having a telephone section and a television section.

2. Description of the Related Art A conventional telephone-equipped television has a configuration as shown in FIG. Hereinafter, an example of a conventional television with a telephone will be explained with reference to all the drawings. In Fig. 3, it is composed of a telephone section 20 and a television section 19, and the telephone section 2o and the television section 19 have no circuit connection. . That is, the telephone section 20 and the television section 19 are operating independently.

Problems to be Solved by the Invention However, with the above configuration, when calling the other party, one must put the receiver to the ear, dial tone, dial signal 9 ring tone.

This has the problem of having to listen to telephone signals such as busy tone to know the operating status of the telephone and confirm whether or not it is possible to talk to the other party.

In view of the above four points, the present invention aims to provide a complete television with a telephone that allows the user to know the operating status of the telephone and to talk to the other party without having to place the receiver of the telephone to the ear.

Means for Solving the Problems In order to achieve the above object, the present invention includes means for connecting the telephone section and the television section in a circuit, detecting the operating state of the telephone, and displaying the operating state on the entire cathode ray tube. It is structured as follows.

Effect of the Invention With the above-described configuration, the present invention displays the operating status of the telephone on a cathode ray tube, so that it can be visually checked even if the telephone receiver is not at full strength when the receiver is placed to the ear.

Embodiment Hereinafter, a television with telephone according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the configuration of a telephone-equipped television in one embodiment of the present invention. Further, FIG. 2 is a diagram showing an example of its operating state. In the figure, 1 is an antenna, 2 is a tuner/'l/IF circuit, 3 is a color demodulation circuit, 4 is a TV-telephone switching circuit, 5 is a cathode ray tube, 6 is a telephone, 7 is a dial tone detection circuit, and 8 is a dial. Signal detection circuit, 9 is a ringing tone detection circuit, 10 is a busy tone detection circuit, 11
12 is a reverse signal detection circuit, 12 is an off-hook display circuit,
13 is a dialing display circuit, 14 is a calling front foot circuit, 1
5 is a busy display circuit, and 16 is a call availability display circuit.

In the above configuration, when you pick up the handset (not shown) of the telephone set 6 to make a call, a dial tone sounds? Tone detection circuit 7
is detected. When the dial tone detection circuit 7 detects the dial tone, the off-hook display circuit 12 is activated by the detection output, and the characters "off-hook" are displayed in the form of a sub-screen on a part of the cathode ray tube 5 through the entire TV-telephone switching circuit 4. Ru.

Here, when dialing is performed, the dial signal detection circuit 8 detects the dial signal. When the dial signal detection circuit 8 detects, the detection output causes the dial display circuit 13 to
is activated, and the characters "Dialing in progress" are similarly displayed on the cathode ray tube 5 through the entire TV/telephone switching circuit 4. Similarly, when all the other parties are calling, the words "Ringing", when the other party is busy, "Busy", and when the other party is answering, the words "Available" are displayed on the CRT S. .

If you make a call while receiving TV, the TV signal will be sent to antenna 1,
Tuner/VIP circuit 2, color demodulation circuit 3, TV/
The entire telephone switching circuit 4 is connected to the cathode ray tube 5, and the second
A television screen 17 shown in the figure is displayed. The operating state of the telephone is determined by, for example, when the handset is picked up, a dial tone is detected by the dial tone detection circuit, the off-hook display circuit 12 is fully activated, and the "off-hook" display signal is passed through the entire iTV/telephone switching circuit 4 and the second
A superimposed field is placed on the cathode ray tube 5 as shown in the figure.

Here, 18 is a telephone operation status screen.

Effects of the Invention As described above, according to the present invention, the operating status of the telephone is displayed on the cathode ray tube. When making a call, wait to see if the person on the other end is answering, then hang up the phone. Also, if you make a call while watching TV, you only need to pick up the phone after the other party answers, so you can watch the entire TV broadcast during that time. have
