This service has already been started in the United States, and any corresponding telephone displays its caller ID information or the like on a small display built into the telephone or a single small display device.

However, when a user uses such a telephone to receive a calling telephone number display service, the user cannot confirm the calling telephone number unless he is near the telephone. For example, when a user receives a call from a caller who does not want to answer the call, such as a prank call, the user must move close to the telephone when receiving the call and be equipped with the telephone. It is necessary to check the information displayed on the small display or the like, and then determine whether to answer the telephone, which is extremely inconvenient.

The present invention has been made in view of such circumstances, and when receiving a calling telephone number display service, information relating to the caller is transmitted to a television receiver or the like without moving to the vicinity of the telephone. It is an object of the present invention to provide a telephone information display device that can be checked.

Features.

[0006] The character generating means generates a character signal based on the sender information received by the sender information receiving means. The display means displays the caller information together with, for example, an image of a television program based on a combined signal obtained by combining the character signal and the television signal.

Further, the telephone information display device according to the present invention comprises:
Caller information receiving means for receiving caller information from a communication signal; character generating means for generating a character signal based on the caller information; and synthesizing the character signal and the video signal to output a synthesized signal to the outside And a display means for displaying information about the caller based on the character signal.

Then, based on the sender information received by the sender information receiving means, the character generating means generates a character signal. The display means displays the caller information based on the character signal. The signal combining means is
The character signal and the video signal are combined, and the combined signal is supplied to, for example, an external monitor device.

A telephone information display method according to the present invention receives caller information from a communication signal, generates a character signal based on the caller information, and combines the character signal with a television signal to generate a combined signal. And displaying the caller information based on the synthesized signal.

[0010] Then, a character signal is generated based on the received sender information. Based on the synthesized signal obtained by synthesizing the character signal and the television signal, the sender information is displayed together with, for example, a video of a television program.

Then, such a transmission ID signal is transmitted to the television receiver 30 via a telephone line.

Then, in step S5, when the control circuit 4 receives the transmission ID signal via the ID receiving circuit 25, the control circuit 4 proceeds to step S6, opens the switch 23 to open the DC loop, and proceeds to step S7. On the other hand, when the local exchange receives the reception completion signal (signal indicating that the reception of the transmission ID information is completed) obtained by breaking the DC loop, the calling signal (the transmission ID information) is at least 0.3 seconds later. (A signal indicating that the reception has been completed).

In step S7, the control circuit 4 closes the switch 27, connects the telephone line to the externally connected telephone, and proceeds to step S8. This allows the externally connected telephone to transmit a calling signal via the telephone line, and to ring when receiving the calling signal. In addition, be careful not to ring the external telephone.
At this time, as will be described later in detail, the speaker 14 may emit a warning sound, and the caller's telephone number may be displayed on the CRT 11 to notify the user.

In step S8, the control circuit 4 searches the memory 5 for data relating to the transmission ID signal (sender), and proceeds to step S9.

In step S9, the control circuit 4 causes the character generator 9 to generate a character signal based on the transmission ID signal, and reads out the data relating to the sender from the memory 5 based on the data. Causes the generator 9 to generate a character signal. This character signal is combined with the video signal from the tuner / external input selection circuit 8 and supplied to the CRT 11. Then, on the CRT 11, an image is displayed on the screen, and information on the caller is displayed at an end of the screen. Specifically, the monitor device displays the telephone number of the caller, the name, corporate name, affiliation, etc. of the caller stored in the memory 5, or indicates the reason when the telephone number is not displayed. One of "P", "O", and "C" is displayed.

The user confirms the information on the caller displayed on the monitor device or the like, determines whether or not to call the externally connected telephone, and may or may not respond to the externally connected telephone. it can. When the user responds to the ringing tone of the externally connected telephone, the local exchange receives the secondary response signal obtained by closing the DC loop, as shown in FIG. And L
The polarity is restored to enable communication.

In the television receiver 30, the control circuit 4 does not generate a ringing tone of the externally connected telephone.
However, a warning sound such as “pong” may be emitted to the speaker 14 via the tuner / external input selection circuit 8 or the like. Therefore, the user can know that the call has been received while watching the television program on the television receiver 30 without having to use the externally connected telephone, and the call can be received without disturbing the surrounding people. You can know that.
