BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice mute circuit of a television during a wireless telephone call. In particular, the present invention relates to a wireless mute circuit for detecting a call signal of a wireless telephone transmitted from a mobile station (handset) of a wireless telephone. It relates to a voice mute circuit of.

At present, a desired voice level is set in a television using a volume control provided on the front control panel or an up / down button provided in a remote control for remote control. .

In addition, the telephone call method recently adopted in accordance with the development of communication technology has been developed and widely used to overcome the limitation of the range of use caused by the wired phone method. In such a radiotelephone method, call and call signals are distributed wirelessly in a mobile station (handset) of a radiotelephone for enabling radio communication for each radiotelephone subscriber.

However, when a call signal of a wireless telephone set adjacent to the television arrives while the television is being viewed, the call is disturbed by the audio signal output from the television. There was the hassle of using to reduce or mute the voice and then make a phone call or move the phone as far as possible from the television.

Therefore, the present invention is to provide the same channel for automatic channel selection on the television, so that when the call and call signal to the wireless telephone of your own country to automatically mute the audio signal of the television during the radio telephone call The purpose is to provide a mute circuit.

In order to achieve the above object, according to the present invention, the radio call signal from a mobile station (handset) of a radiotelephone, which is configured inside a television and transmits a radio call signal to a radiotelephone body line-connected to a subscriber line. Receiving detection means for receiving detection, a wireless telephone call signal detecting means for analyzing a wireless call signal received by the receiving detecting means and outputting a call signal informing the setting of the call mode, and a call signal from the wireless telephone call signal detecting means. Main mute means for outputting a volume control signal in response to the voice control means, and a voice muting means for muting a voice output for a voice signal on the television in accordance with the volume control signal output from the main control means. The circuit provides.

In the voice mute circuit of a television in a wireless telephone call according to the present invention configured as described above, the telephone signal of a subscriber using a wireless telephone is detected by a wireless telephone call signal detection means built in the television to control the microcomputer to control the voice of the television. By muting the signal, it is possible to prevent the influence of the telephone call by the audio signal of the television during the telephone call.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a configuration in which a voice mute circuit of a television is applied during a wireless telephone call according to the present invention. In FIG. 10, reference numeral 10 denotes a main body of a wireless telephone connected to a subscriber line. An automatic channel tuning device for automatically setting up a call channel transmitted from a wireless telephone mobile station (handset) 20 configured to enable a mobile call to a subscriber is provided, which is optimal for calls and calls from the wireless telephone mobile station 20. Select a call channel to access the wireless call channel.

Further, reference numeral 30 denotes a voice mute circuit of a television during a wireless call according to the present invention, which includes an antenna 32 as a call signal detecting means for detecting a call signal transmitted from the radio telephone mobile station 20, and the main body of the radio telephone. A call signal detection unit 34 configured to perform the same operation as that of the automatic channel tuning device equipped at 10 and outputting a telephone call signal, and a voice muting control signal in response to the telephone call signal output from the call signal detection unit 34. And a voice muting unit 38 for muting the audio signal of the television according to the voice muting control signal output from the microcomputer 36. Preferably, the voice muting circuit ( 30) is installed inside the TV.

Next, the voice muting operation of the television during the wireless call according to the present invention configured as described above will be described in detail with reference to the flowchart shown in FIG.

First, in step S41 and S43 of FIG. 2, if a radio call signal is generated from the radio telephone mobile station (handset) 20 for the radio telephone main body 10 connected to the subscriber line (Tip, Ring), the call mode is set. In step S45 of FIG. 2, the optimal channel is tuned by the automatic channel selecting apparatus provided in the radiotelephone main body 10, and the radiotelephone call is made according to a normal communication protocol.

At the same time, in step S47 of FIG. 2, a call call signal transmitted wirelessly from the movement 20 of the radio telephone is applied to the call signal detection unit 34 through an antenna 32 dedicated to receiving call signals installed in the television. The other call signal detection unit 34 outputs a call signal indicating the setting of the call module.

This call signal output is input to the microcomputer 36, and a voice muting signal is generated from the microcomputer 36 in step S49 of FIG. 2, and applied to the voice muting 38 at the next stage.

Accordingly, in step S51 of FIG. 2, the voice muting unit 38 mutes the voice output of the TV broadcast signal output to the speaker (not shown) to prevent the influence of the voice signal output from the TV during the wireless telephone call. .

Subsequently, in step S53 of FIG. 2, the microcomputer 36 determines that the call ends when the call signal is turned off from the radio telephone mobile station 20 and the call signal is not output from the call signal detection unit 34. By outputting a signal and releasing the voice muting by the voice muting unit 38, the audio signal of the TV broadcast is controlled to be normally output.

On the other hand, according to the present invention, it is also possible to release the voice muting by using the voice mute function key provided in an input device such as a remote control, for example, in step S53 of FIG.

In addition, the voice mute circuit in the wireless telephone call according to the present invention is not limited to the audio output muting of the television, and when such a voice mute circuit is employed, it is applied to an audio set or an audio / video (A / V) device or the like. The same effect can be obtained.

As described above, according to the voice mute circuit in the wireless telephone call according to the present invention, the wireless telephone signal of the wireless telephone is captured by the television and the audio output of the television is automatically muted. Disruption of the call can be eliminated and a good fixed line call can be ensured accordingly.
