Sub-voice character processing device and main method when listening to main voice output from multi-TV receiver

The present invention relates to a voice multiple television receiver (hereinafter referred to as a TV), and more particularly, when a sub voice is selected when listening to a main voice output from a voice multiple TV to a speaker, the sub voice data processed by the sub voice processor is characterized. Sub-voice character processing device when listening to the main voice output from the speaker of the multi-TV receiver that allows the viewer to recognize the sub-audio as text data while sequentially converting the data into the CRT screen and listening to the main voice output from the speaker And to a method thereof.

In general, as shown in FIG. 1, the multi-audio TV includes a microcomputer 200 for controlling overall operations of the TV by manipulation of the key input unit 220, and a memory for storing data to be processed by the microcomputer 200. A tuner 100 for receiving a broadcast signal of a channel selected by the tuning voltage output from the microcomputer 200 from the antenna ANT, and a video signal of the broadcast signal received by the tuner 100. The image processor 300 to process the image, the image amplifier 320 for amplifying the image signal output from the image processor 300, and the vertical / horizontal synchronization signal processed by the image processor 300 CRT ( 400) a vertical / horizontal synchronization processor 340 for deflecting a vertical synchronization signal and a horizontal synchronization signal of a video signal displayed on a screen; and a CRT (CRT) configured to receive a video signal output from the image amplifier 320 and display it on a screen; 400) and the tuner 100 A voice processor 500 for processing a voice signal of the received broadcast signal, a main voice processor 520 for separating and processing only a main voice signal (eg, Korean) from the voice signal processed by the voice processor 500, The sub-voice processor 540 for separating and processing only a sub-audio signal (for example, a foreign language) from the voice signal processed by the voice processor 500, and the main audio processor 520 and the sub-audio processor 540 It is largely composed of a voice amplifier 560 for amplifying the main / sub-audio signal to a predetermined level, and a speaker 600, 620 to receive and output the voice signal output from the voice amplifier 560.

In the general voice multiplex TV configured as described above, when a viewer selects a channel to be watched by manipulating the key input unit 220, the microcomputer 200 recognizes the generated channel voltage and applies it to the tuner 100. .

Accordingly, the tuner 100 receives the broadcast signal of the channel selected by the tuner voltage generated by the microcomputer 200 from the free space through the antenna ANT and transmits the broadcast signal to the image processor 300 and the voice processor 500. Enter it.

Thus, the image processor 300 processes only the image signal from the broadcast signal input from the tuner 100 by the control signal of the microcomputer 200 and supplies the processed image signal to the image amplifier 320.

Therefore, the image amplification unit 320 amplifies the video signal to a level that can be displayed on the screen of the CRT 400 and supplies it to the CRT 400, so that the video signal transmitted from the broadcasting station to the free space is displayed on the screen. To watch.

At this time, the vertical / horizontal synchronization processor 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 by the image processor 300.

In addition, the voice processor 500 processes only the voice signal among the broadcast signals input from the tuner 100 and outputs the processed voice signal to the main voice processor 520 and the sub voice processor 540.

That is, the main voice processor 520 separates and processes only the main voice signal (for example, Korean) from the voice signal processed by the voice processor 500 of the front end and inputs it to the voice amplifier 560, and the sub-voice processor ( The 540 separates and processes only a sub-audio (for example, foreign language) signal from the voice signal processed by the voice processor 500 of the previous stage and inputs it to the voice amplifier 560.

Accordingly, the voice amplifier 560 amplifies the voice signal of the Korean language separated by the main voice processor 520 and the voice signal of the foreign language separated by the sub-voice processor 540 to a predetermined level, respectively. ), The viewer can simultaneously listen to the main voice of Korean language with background music and the sub-voice of foreign language with background music through voice multiple broadcasting.

However, a general voice multi-TV is generally a main voice when listening to a voice multiple broadcast output to the speakers 600 and 620 while watching an image displayed on the CRT 400 screen. The Korean voice is output loudly, and the negative voice in foreign language is output small.

Therefore, when a viewer watches the video output on the CRT 400 screen while simultaneously listening to the main / sub audio output to the speaker, it is difficult to listen to the foreign language output to the sub audio.

In particular, it may not be a problem when the surroundings are quiet, but when the surroundings are noisy, the problem of not being able to listen to the foreign voice more and more is caused by the influence of noise.

The present invention has been made to solve the above-mentioned problems, and for this purpose, if a viewer selects a sub-voice when listening to a main voice that is multi-broadcasted, the sub-audio data is processed as text data and sequentially displayed on a CRT screen. In this way, the viewer can listen to the main voice and check the sub-voice as text data.

Another object of the present invention is to listen to the main voice through the speaker, the sub-voice is to see and confirm the text data displayed on the CRT screen, so that the viewer can recognize the sub-voice data accurately even in a noisy surroundings.

In order to achieve the above objects, the present invention, if the viewer selects the sub-audio while listening to the main audio output to the speaker, the sub-audio data is corrected by correcting the error generated by searching the sub-processed data with the text data. It is a well-known feature that the text processing means for sequentially displaying data on a CRT screen is included in an existing voice multiple TV.

And an output unit 770 for outputting the input to the image processor 300.

3 is a flowchart illustrating an operation relationship of a voice multiple television receiver with a sub-voice character processing apparatus according to the present invention.

It is determined whether the TV is on (S301), if the TV is on, viewing the TV via voice multiplexing (S302), and determining whether to process the sub-audio as text data while listening to the main voice by voice multicasting. And if it is determined that there is no key input and thus does not process the sub-voice as text data, the step (S314) of continuously listening to the main voice is performed. If the sub-audio is selected (S304), if the sub-audio is selected, the character ID is retrieved from the voice signal to be processed sub-speech (S305), and storing the text data (S306), Reading and decoding the stored character data (S307), correcting an error occurring in the decoded character data (S308), sequentially displaying the retrieved character ID and the corrected character data (S309), and sequentially table Outputting the text data (S310), displaying the text data sub-voice on the CRT screen (S311), and if the text data sub-voice is displayed on the CRT screen, whether to finish the sub-voice text data is displayed. In step S312, if there is no key input as a result of determination, the process returns to step S304 if the negative character data is to be continued, and if there is a key input to terminate the sub-negative character data, ending the sub-negative character data. (S313), and listening to the main voice when the sub-voice characterization is completed (S314).

Looking at the working state of the present invention made as described above are as follows.

When the viewer selects the voice multicast channel to be watched while the TV is turned on (S301) by operating the power key of the key input unit 220, the corresponding microcomputer 200 selects the corresponding channel. A voltage is generated and applied to the tuner 100.

Accordingly, the tuner 100 receives the broadcast signal of the channel selected by the tuner voltage generated by the microcomputer 200 from the free space through the antenna ANT and transmits the broadcast signal to the image processor 300 and the voice processor 500. Enter it.

Thus, the image processor 300 processes only the image signal from the broadcast signal input from the tuner 100 by the control signal of the microcomputer 200 and supplies the processed image signal to the image amplifier 320.

Therefore, since the image amplifier 320 amplifies the video signal to a level that can be displayed on the screen of the CRT 400 and supplies it to the CRT 400, the video signal transmitted from the broadcasting station to the free space is displayed on the screen.

At this time, the vertical / horizontal synchronization processor 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 by the image processor 300.

In addition, the voice processor 500 processes only the voice signal among the broadcast signals input from the tuner 100 and outputs the processed voice signal to the main voice processor 520 and the sub voice processor 540.

That is, the main voice processor 520 separates and processes only the main voice signal (for example, Korean) from the voice signal processed by the voice processor 500 of the front end and inputs it to the voice amplifier 560, and the sub-voice processor ( The 540 separates and processes only a sub-audio (for example, foreign language) signal from the voice signal processed by the voice processor 500 of the previous stage and inputs it to the voice amplifier 560.

Accordingly, the voice amplifier 560 amplifies the voice signal of the Korean language separated by the main voice processor 520 and the voice signal of the foreign language separated by the sub-voice processor 540 to a predetermined level, respectively. So that the viewer can watch the video output on the screen of the CRT 400 while simultaneously listening to the main voice of the Korean language including the background music and the sub-audio of the foreign language including the background music through the voice multicast (S302). do.

While listening to the main voice in the voice multiple mode while watching the TV, the microcomputer 200 determines whether to process the sub voice as text data (S303).

As a result of the determination, if there is no key input for processing the sub-voice as text data, the key input unit 220 continuously outputs the main voice through the speakers 600 and 620 to allow the viewer to listen to the main voice (S314). Make sure

However, if there is a key input for processing the sub-voice as text data in the key input unit 220 as a result determined in step S303, the microcomputer 200 is input from the key input unit 220. The signal is processed to output a control signal to the voice selector 710 of the text processing apparatus 700 so that the voice selector 710 selects the sub-voice processed by the voice processor 500 (S304).

Therefore, the character ID search unit 720 searches for the character ID among the sub-voice data processed by the sub-voice processing unit 540 to convert the searched character ID into the character data (S305).

Characters data data generated by the text ID search unit 720 are stored in the text data storage unit 730 (S306), and the searched text data is sequentially input to the display unit 760.

At this time, the decoder 740 decodes the character data stored in the character data storage unit 730 (S307) and inputs it to the error correction unit 750.

Therefore, if an error occurs in the decoded character data, the error correction unit 750 corrects an error generated by the standard character data (S308) and inputs the result to the sequential display unit 760.

The error correction unit 750 is in a state of storing standard character data.

Thus, when the display unit 760 sequentially displays the character ID retrieved by the character ID search unit 720 and the character data corrected by the error correction unit 750 (S309), the output unit 770 is sequentially displayed. The text data is output (S310) and input to the voice processor 300.

That is, the voice processor 300 processes the input text data and displays the sub-voice, which is the text data together with the video signal, on the screen of the CRT 400 through the image amplifier 320 (S311), so that the viewer hears the main voice. This allows you to check the sub-voices represented by character data.

When the negative data converted to text data is displayed on the screen of the CRT 400, the microcomputer 200 determines whether to finish converting the negative data to text data (S312).

If there is no key input for terminating the sub-negative character data in the key input unit 220 as a result of the determination, the process returns to step S304 to continue the above processes from the process.

On the other hand, if there is a key input for ending the sub-voice character data in the key input unit 220 as a result determined in step S312 (microcomputer 200) terminates the sub-voice character data (S313) the viewer hears only the main audio ( S314).

As described above, in the present invention, when a viewer selects a sub-voice when listening to a main voice, the sub-audio data is processed as text data and displayed sequentially on a CRT screen so that the viewer listens to the main voice. By confirming with the text data, the viewer can recognize the sub-voice data accurately even in a place where the surroundings are noisy.

The present invention has been described with respect to the sub-voice character processing apparatus and method thereof when listening to the main voice output to the voice multi-TV receiver as described in the claims, but the present invention is not limited to this and various skilled in the art Its applications and variations will be possible.
