Elements are given the same reference numerals as in FIG. 1 and detailed description thereof will be omitted.

In FIG. 2, reference numeral 10 denotes a control signal input unit including a voice multiple key 10a for selectively setting the voice multiple mode and a language selection key 10b for selecting a delay processing language for a given foreign country. If a specific language is selected by the language selection key 10b of the control signal input unit 10 to control a related device so that a corresponding language output through one speaker may be output in a delayed state for a predetermined time when the voice multiple function is performed.

The voice signal delay unit applies the delayed voice signal to the voice amplifier 24 after delaying the signal.

Reference numeral 33 is a language-specific delay time storing unit that stores data corresponding to an appropriate delay time for each language.

Next, the normal TV broadcast signal reproduction processing operation of the television having the above-described configuration will be briefly described.

First, the control unit 12 applies a predetermined tuning voltage VT to the tuner 18 on the basis of the channel tuning signal input from the control signal input unit 10, and the tuner 18 supplies the corresponding tuning voltage ( On the basis of the VT), a tuning operation for a specific channel among a plurality of channels received through the antenna is performed. Subsequently, a broadcast signal for a channel tuned by the tuner 18 is applied to the audio IF module 20 and to the video IF module 26, and the audio IF module 20 receives the corresponding broadcast signal. After the IF amplification, only the audio signal is detected and applied to the audio signal processor 22. The video IF module 26 IF amplifies the corresponding broadcast signal and then detects only the video signal and applies it to the video signal processor 28. do.

Accordingly, the voice signal processor 22 performs a reproduction process on the voice signal, and then applies the voice signal to the voice amplifier 24 through the L / R channel, and the voice amplifier 24 ) Is amplified so that the corresponding audio signal can be reproduced and output through the L / R speaker and is applied to the L / R speaker to output a predetermined sound through the L / R speaker.

At the same time, the image signal processing unit 26 performs a reproduction process on the video signal, and then applies the RGB signal to the video amplifier 30 according to the video signal processing unit 30. A predetermined image is outputted through the CRT by amplifying and reproducing it to be reproduced and output through the CRT.

Next, with reference to the flowchart shown in Figure 3 will be described in detail the operation of the audio output restriction device in a television with a voice multiple function according to an embodiment of the present invention.

First, when the voice multiple key 10a of the control signal input unit 10 is operated by the viewer to set the voice multiple mode in the control unit 12 (step 60), the control unit 12 controls the voice signal processing unit ( 22) a predetermined control signal is applied so that Korean and foreign languages are output through the L / R channel of the voice signal. The voice signal processor 22 corresponds to two types applied from the voice IF module 20. The audio signal is reproduced independently of each other, and each of the audio signals is separated into L and R channels and output.

Accordingly, the voice amplifier 24 separately receives the corresponding voice signals through the L channel input terminal and the R channel input terminal, independently amplifies the signals, and then applies them to the L-speakers and the R-speakers connected to the rear stages. Through the speaker and the R-speaker, 'Korean' is output through the other language, for example, the L-speaker, and 'English' is output through the R-channel (step 62).

The controller 12 determines whether the language delayed by the control signal input unit 10 is selected while performing the voice multiple function by the above-described operation (step 64). As a result, the viewer determines that the control signal input unit is selected. By repeatedly operating the language selection key 10b configured on (10), if a specific language is selected from among languages provided with voice multiplication, for example, English / Japanese / French / German / Chinese (YES in step 64), the control unit 12 ) Reads the delay time corresponding to the selected language, for example, "English", from the language-specific delay time storage unit 33 and based on the delay time data read from the language-specific delay time storage unit 33. The predetermined delay control signal DT is applied to the signal delay unit 32 (step 66).

On the other hand, in step 64, the control unit 12 controls the OSD processing unit 16 so that the OSD characters corresponding to the language cyclically selected by the language selection key 10b of the control signal input unit 10 are CRT. To be displayed on the screen.

At the same time, the control unit 12 applies a predetermined control signal to the voice signal processing unit 22, and the voice signal processing unit 22 outputs a voice signal output through the L channel to the voice signal delay unit 32. As a result, the voice signal for 'English' applied to the voice signal delay unit 32 is delayed for a delay time by the delay control signal DT, and then the L channel of the voice amplifier 24 is performed. Is applied to the input stage (step 66).

Accordingly, the voice amplifier 24 includes a voice signal for 'Korean' from the voice signal processor 22 input through the R channel input terminal and the voice signal delay unit input through the L channel input terminal ( By amplifying the audio signal for 'English' from 32) and applying it to the L-speaker and the R-speaker connected to the rear stage, two languages having a predetermined time difference are separately output through the L / R speaker (step 70).

Therefore, if a viewer who is not good at a foreign language sets the voice multi mode, the Korean language is output through one speaker and the corresponding foreign language is output through the other speaker after a predetermined time elapses so that the viewer understands the foreign language about Korean. It will be a great help.

As described above, according to an exemplary embodiment of the present invention, the apparatus for limiting audio output in a television equipped with a speech multiplier function can maximize the language learning efficiency for a viewer who has set the audio multiple mode for language learning. do.
