In FIG. 2, the same components as those of FIG. The numbers will be omitted and the detailed description thereof will be omitted.

In FIG. 2, reference numeral 200 denotes a remote control device having a separate function key for the viewer to select the recorded voice guidance broadcast listening, and 210 receives an infrared signal transmitted from the remote control device 200 and transmits the same. The receiver 220 converts and outputs the signal to control the entire apparatus according to the code signal input from the receiver 210 as in a normal television receiver, and in particular, the frequency detector 230 and the noise detector (described later). A microprocessor as a control unit which executes a voice guidance broadcasting storage function in a state in which a predetermined mute signal is input to the voice processing unit 10 according to the detection signal from the 240.

Reference numeral 230 denotes a frequency detector for detecting a pilot signal according to voice guidance broadcasting transmitted from a broadcasting station from a composite video signal output from the image detector 6, and 240 denotes a case of a television receiver. The noise detection unit is installed at a predetermined position and detects ambient noise of the television. When the detected noise is equal to or higher than a predetermined value, a predetermined high level signal is applied to the microprocessor 220.

That is, the noise detector 240 is a microphone 240 ₁ for converting the ambient noise in which the television receiver is installed into an electrical signal, and an amplifier for amplifying the audio signal output from the microphone 240 ₁ . 240 ₂ ), an integrating circuit 240 ₃ for integrating the audio signal output from this amplifying unit 240 ₂ , and when the output level output from the integrating circuit 240 ₃ is larger than a predetermined reference value, And a comparator 240 ₄ which outputs a noise detection signal.

Next, the operation of the apparatus having the above-described configuration will be described using the flowchart shown in FIG.

First, in the power ON state of the television, the microprocessor 220 reproduces the broadcast signal of a normal television (step ST301). In addition, when a pilot signal corresponding to a specific voice announcement broadcast transmitted from a broadcasting station is detected from the composite video signal output from the image detector 6 and a predetermined detection signal is applied from the frequency detector 200 (step ST302). The microprocessor 220 detects the noise around the television based on the detection signal from the noise detector 210 (step ST303).

That is, when the microprocessor 220 detects that the high level signal is applied from the noise detector 240 (step ST304), that is, when the ambient noise is above a predetermined level, the microprocessor 220 mutes a predetermined amount to the voice processor 10. In addition to inputting a signal (step ST305), the voice signal for the voice guide broadcast output from the voice detector 5 is converted into digital data through the A / D converter 250 and the voice signal storage unit ( 260) (step ST306).

That is, the voice guidance broadcast from the broadcasting station is automatically stored in the state where the voice signal output through the speaker 12 is muted.

On the other hand, when the high level signal is not applied from the noise detector 240 in step ST304, the voice signal according to the voice guidance broadcast processed by the voice processor 10 through the voice detector 5 operates normally. In the same manner as in the output through the speaker 12 (ST307).

In addition, although not shown in FIG. 3, when the high level signal is applied from the noise detector 240, the microprocessor 220 controls the OSD generator 13 to indicate that the voice guidance broadcast is currently stored. It is displayed through the CRT screen.

FIG. 4 is an operation flowchart illustrating a process in which a viewer selects and listens to a voice guidance broadcast stored with respect to the device of FIG. 2, and the viewer listens to the voice guidance broadcast of the limoncon apparatus 200. When a predetermined function key is input (step ST401), the microprocessor 220 controls the switching unit 280 and checks whether there is data stored in the voice signal storage unit 260 (step ST402). If there is data, the digital data stored in the voice signal storage unit 260 is output through the D / A converter 270 (ST 403). Therefore, in this case, the voice signal stored in the voice signal storage unit 260 is processed by the voice processing unit 10 through the switching unit 270 to output the voice guidance broadcast stored through the speaker 12. (ST404).

In addition, when there is no data stored in the voice signal storage unit 260 in step ST402, a predetermined error message is output on the CRT 17 on the OSD screen.

That is, according to the embodiment, when a specific voice announcement from a broadcasting station is received, the voice announcement is automatically stored in a state in which the voice signal output through the speaker is muted when the ambient noise is greater than a predetermined level.

The stored voice guidance can then be selectively listened to by the viewer.

In addition, this invention is not limited to the said Example, It can implement in a various deformation | transformation in the range which does not deviate from the technical summary of this invention.

As described above, according to the present invention, when a specific voice announcement is received from a broadcasting station when watching TV, when the ambient noise is greater than a predetermined level, the voice announcement is output in a state where the voice signal output through the speaker is muted. It is possible to realize a television receiver equipped with a voice guidance broadcast auto-save function in a voice mute state when the noise is to be automatically stored.
