(Step S314). If it is determined that there is no key input and the selected specific tone color is to be continuously amplified, the process returns to step S304. If the amplification is to be terminated, As far as to shut down the forward voice amplifier shows a made of an step (S315) to listen to the general voice non-specific amplification is voice.

The operation state of the present invention is as follows.

When the viewer operates the key input unit 220 to supply power and the TV is turned on (S301), the microcomputer 200 recognizing the selected channel selects the channel selection voltage corresponding to the selected channel and outputs the selected channel selection voltage to the tuner 100 .

The tuner 100 receives a broadcast signal of a channel selected by the tuning voltage generated by the microcomputer 200 from a free space through an antenna ANT and outputs a broadcast signal to the video processor 300 and the audio processor 500 .

Thus, the image processor 300 processes only the video signal from the broadcasting signal input from the tuner 100 according to the control signal of the microcomputer 200, and supplies the processed video signal to the video amplifying unit 320.

Accordingly, the image amplifying unit 320 amplifies the image signal up to a level that can be displayed on the screen of the CRT 400, and supplies the amplified image signal to the CRT 400, so that the image signal transmitted from the broadcasting station to the free space is displayed.

At this time, the vertical / horizontal synchronization processing unit 340 deflects the image signal displayed on the screen of the CRT 400 in the vertical direction and the horizontal direction based on the vertical synchronization signal and the horizontal synchronization signal processed in the image processor 300.

The voice processor 500 processes only voice signals from the broadcast signals input from the tuner 100 and inputs them to the voice amplification unit 520.

Accordingly, the audio amplifying unit 520 amplifies the audio signal processed by the audio processor 500 to a predetermined level and outputs the amplified audio signal to the speakers 600 and 620 so that the viewer can watch the video output on the CRT 400 screen, (S302).

While listening to the TV, the microcomputer 200 determines whether a specific tone color is selected and amplified (S303) while listening to a voice output to the speakers 600 and 620. [

If the determined result is that there is no key input from the key input unit 220 and the sound selection unit 712 does not select a specific tone color, the viewer can select a tone color to be processed by the voice processor 500 through the voice amplification unit 520 (S315) a general voice which is amplified to a predetermined level and not amplified with a specific tone color outputted to the speakers (600) and (620).

However, if it is determined that a specific tone color (e.g., animal crying sound) output to the speakers 600 and 620 by the sound selection unit 712 is selected and amplified by the key input unit 220, The sound selection unit 712 of the adjustment device 700 is operated to select data for calling a specific tone color (e.g., animal crying sound) stored in the sound sample storage unit 710 by key operation (S304) (718).

Here, when the viewer operates the sound selection unit 712 to select data for calling up a specific tone color (e.g., animal cry) stored in the sound sample storage unit 710 by key operation, the selected signal is also supplied to the microcomputer 200 .

At this time, the digital processor 714 processes a voice signal including a specific tone color (e.g., an animal cry) processed in the voice processor 500 as an analog signal into a digital signal (S305) And the code data of the processed voice signal is detected (S306).

Therefore, the comparison determination unit 718 reads the tone color data from the sound sample storage unit 710 according to the data selected and input by the sound selection unit 712, and compares the tone color data with the code data detected and input by the code detection unit 716 (S307), it is determined whether a specific tone color of the data selected by the sound selection unit 712 exists in the compared data (for example, the tone color data retrieved from the sound sample storage unit and the code data detected and input by the code detection unit) do.

If there is no specific tone color (e.g., animal crying sound) of the data selected by the sound selecting unit 712 in the detected code data, the general voice data not selected through the general sound coding unit 722 is encoded (S309- 1), converts the audio data coded by the D / A conversion unit 726 into an analog signal (S310-1), and inputs it to the output unit 730. [

On the other hand, if there is a specific tone color of the data selected by the sound selecting unit 712 (for example, animal crying sound) in the code data detected as a result of the determination in step S308, the sound selecting unit 720 (E.g., animal crying sound) of the data selected in step S309.

(For example, animal crying sound) data coded in the selected sound coder 720 is converted into an original analog signal via the D / A converter 724 (S310) and input to the level controller 728 do.

The level control unit 728 amplifies data related to a specific tone color (for example, animal crying sound) input by an analog signal according to a control signal input from the microcomputer 200 to a level selected by the viewer (S311) ).

Here, the level control unit 728 determines the degree of amplification by the data selected by the key operation of the sound selection unit 712 and input to the microcomputer 200, thereby allowing the viewer to listen to a specific tone color (E.g., an animal cry) to the speaker 600 (620) if the volume level is lowered to a certain level or less or completely removed.

Accordingly, the output unit 730 synthesizes a general speech signal converted into an analog signal in the D / A conversion unit 726 and a specific tone color (for example, animal crying sound) amplified by the level control unit 728 And outputs it to the audio processor 500.

Therefore, the voice processor 500 processes the input data synthesized in the output unit 730, amplifies the data to a predetermined level through the voice amplification unit 520, and outputs the amplified voice to the speakers 600 and 620, It is possible to clearly listen to a specific tone (e.g., a cry of an animal) (S313).

The microcomputer 200 determines whether the specific tone color amplification selected by the sound selection unit 712 is to be terminated (S314) while the synthesized data is output and the specific tone color (e.g., animal crying sound) is clearly heard.

If it is determined that there is no key input for terminating the specific tone color amplification in the key input unit 220, the process returns to step S304 and the process is repeated according to the above procedure.

On the other hand, if the result key input unit 220 determined in step S314 has a key input for terminating the specific tone color amplification and ends the selected specific tone color amplification, the level adjusting apparatus 700 is turned off, Is amplified to a predetermined level through the voice amplifying unit 520 and the general voice output from the speakers 600 and 620 is not amplified (S315).

As described above, according to the present invention, a specific tone color output from a speaker is accurately amplified to a selected tone color level by a viewer, and the tone color is output to a speaker, so that a viewer can listen to a specific tone color according to his / her taste.

In addition, a specific tone color outputted to the speaker can be selected, and a specific tone color that a viewer dislikes can be reduced or removed, and an effect of being able to listen to a voice output to the speaker can be expected.

Although the present invention has been described with reference to a level adjusting apparatus and a method thereof according to a tone color selection output to a speaker of a television receiver as described in the claims, the present invention is not limited thereto, Modifications will be possible.
