JPS6340428A - Incoming signal detecting and displaying device - Google Patents

Abstract

PURPOSE:To exactly recognize the incoming state of a telephone set even in a state of incoming sound is masked by the TV sound by displaying a prescribed incoming display pattern while superposing it on the TV reception picture corresponding to each incoming through the telephone line. CONSTITUTION:An incoming detection signal outputted from an incoming detection circuit 1 is inputted to a pattern generating circuit 2, where a prescribed incoming display pattern signal is generated and inputted to a modulation circuit 3. In the modulation circuit 3, such a high frequency signal as corresponding to the carrier wave of a TV reception signal is modulated by using the incoming display pattern signal, thus modulated signal is inputted to a superimposing generation circuit 4. To the circuit 4, the antenna output for a television receiver 5 is connected, where the above-said modulated signal and the TV reception signal are synthesized and inputted to the receiver 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an incoming call detection display device, and more particularly to a call detection display device that displays the incoming call status on a telephone line on both receiving surfaces of a television receiver. 1- Clarify.

[Conventional technology]

Conventionally, the Yuzu incoming call detection and display device generally uses a speaker or a Bell's sound wave generator as a means for detecting and displaying the incoming call status on a telephone line.

[Problem that the invention seeks to solve]

The conventional incoming call detection and display device described above uses a speaker or a sound wave generator such as a bell to display the incoming call status. Therefore, when the TV is on, the incoming call signal is masked by the sound of the TV, making it difficult to recognize the incoming call.

[Means for solving problems]

The incoming call detection and display device of the present invention includes an incoming call detection circuit that detects an incoming call signal and outputs an incoming call detection signal, and an incoming call detection circuit that inputs the incoming call detection signal to generate and output an eyebrow call pattern signal. a pattern generation circuit, a bamboo modulation circuit that modulates a high-frequency signal corresponding to the carrier wave number of the television reception signal by the above-mentioned waveform pattern signal;
b) A superimpose system that combines the modulated signal σ output from the road and the TV reception signal, and outputs No. 18 that superimposes the TV image and the above-mentioned nursing display pattern on the TV screen and displays "C". Example: Next, the present invention will be described with reference to the drawings.

FIG. 1 shows a bag portion according to an embodiment of the present invention.

This is a diagram. As shown in FIG. 1, this embodiment includes an incoming call output circuit, a pattern generation circuit 2, a modulation circuit 3, a superimposition generation circuit 4, and a television receiver 5.

In FIG. 1, the telephone line 101 is connected to the shield detection circuit 1, and the telephone line 101 is connected to the paid detection circuit 1.
An incoming call is detected without M. If there is a charge, the incoming call detection signal output from the charge detection circuit 1 is input to the pattern generation circuit 2, and the pattern generation circuit 2 generates a predetermined shoulder habit indication pattern signal and inputs it to the modulation circuit 3. be done. In the modulation circuit 3, the frequency signal corresponding to the carrier wave of the television reception signal is modulated by the above-mentioned frequency display pattern signal, and the modulated signal is input to the superinnovation generation circuit 4.

The antenna output of the television receiver 5 is connected to the superimpose generation circuit 4, and the superimposition generation circuit 4 receives the modulated signal based on the incoming call display pattern signal and the television reception sent from the antenna. (
2i signals are combined and input to the television receiver 5.

In the television receiver 5, a television image based on the television reception signal is displayed on the reception screen, and a display pattern according to the front m1 layer clothing indicating pattern signal is also displayed superimposed on the television image.

〔Effect of the invention〕

As explained above, the present invention provides a method for masking the ring tone of the TV audio by displaying a predetermined standard display pattern on the TV reception screen in response to an incoming call on the telephone line. Also, there is an effect that the paid status can be clearly recognized.
