The present invention relates to a voice conversion method for automatically adjusting the voice as the width of the left and right screen size changes on the multi-screen, in particular, when the user changes the width of the screen on the multi-screen control of the screen The present invention relates to an automatic voice conversion method according to a screen size conversion so that a voice ratio can be converted according to a ratio of increasing width.

As shown in FIG. 1, a conventional two-screen TV audio processing circuit includes a first and second tuners 1 and 2 for tuning a broadcast signal transmitted through an antenna ANT according to a control signal. A first and second audio / video processing unit 3 and 4 for separating and outputting a voice signal and a production signal from the broadcast signal tuned through the first and second tuners 1 and 2, and the first audio / An audio processor 5 for amplifying and outputting an audio signal transmitted from the image processor 3 to a level capable of being output, and an output from the audio or second audio / video processor 4 output from the audio processor 5. A selection switch 6 for selecting a voice signal to be used, a microcomputer 7 for outputting a control signal for voice output to each required part, and a tone for the main screen voice selected through the selection switch 6 The tone controller 8 to be emitted to the speakers SP1 and SP2 and the hatching selected via the selection switch 6 It is composed of an amplifier (9) for amplifying a surface voice signal to a predetermined level and outputting the earphone.

As shown in FIG. 5, a circuit configuration of a general digital image signal processor includes a luminance / color signal separator that receives an input composite image signal, separates the luminance signal into a color signal, and generates and outputs a color difference signal. 11) a color decoder 12 that performs filtering and analog / digital conversion on the luminance signal and the color difference signal separated by the luminance / color signal separator 11, and outputs the color difference signal through the color decoder 12; The multiplexer 13 outputs after multiplexing to increase memory efficiency with respect to the memory, the memory 14 storing the luminance signal through the color decoder 12 and the color difference signal through the multiplexer 13, and the memory ( A demultiplexer 16 which demultiplexes the signal transmitted from 14 to produce an original color difference signal, and a luminance signal through the memory 14 and a color difference through the demultiplexer 16. A signal conversion and filtering unit 15 for converting and filtering signals to be displayed on a screen, and a timing control signal generation unit 17 for supplying timing control signals to the respective units and controlling their operation. .

Looking at the conventional technology configured as described above are as follows.

First, referring to the two-screen TV according to FIG. 1, when the user selects the two screens and the corresponding channel, the microcomputer 7 recognizes them and displays the main screen with the first tuner 1. A signal for tuning the channel is output, and a signal for tuning the channel to be displayed on the sub-screen is output to the second tuner 2.

Accordingly, when the first tuner 1 tunes a channel to be displayed on the main screen and outputs the tuned composite video signal to the first audio / video processor 3, the processor 3 outputs an audio signal and a video signal. The audio signal is output to the audio processor 5 by separating the signal from the audio signal.

Therefore, the audio processing unit 5 processes the audio signal and outputs it to the selection switch 6.

Similarly, as the microcomputer 7 outputs a signal corresponding to a channel to be displayed on the sub-screen to the second tuner 2, the second video / tuned composite video signal in which the second tuner 2 tunes the channel. Output to the image processor 4.

Therefore, the second audio / video processor 4 separates the audio signal and the video signal and outputs the audio signal to the selection switch 6.

At this time, since the microcomputer 7 recognizes the channel to be displayed in the main screen and the sub-screen, it controls the selection switch 6 so that the voice of the channel to be displayed in the main screen is transmitted to the controller controller 8, and the sub-screen is displayed. The channel to be displayed is transmitted to the amplifier 9 for the audio signal.

Therefore, the tone controller 8 adjusts the tone of the input voice and outputs it to the speakers SP1 and SP2 so that the voice of the main screen is output through the speakers SP1 and SP2, and the amplifier 9 The voice is amplified to a certain level through the earphone is delivered to the earphone, the voice of the sub-screen is output.

In other words, as shown in FIG. 2, the voice of the main screen corresponding to one screen is output through the speakers SP1 and SP2, and the voice of the sub screen corresponding to the second screen is output to the earphone.

In the case of the double screen as shown in FIG. 3, the voice of one screen is output through the speaker SP1 and SP2, and the voice of the two screen is output through the earphone.

In addition, as shown in FIG. 4, the digital video signal processing in the case of changing the screen size will be described with reference to FIG.

When the composite video signal is input to the luminance / color signal separator 11, the separator 11 separates the luminance signal Y and the color signal C and generates a color difference signal BY (RY) to generate a color decoder. The output is (12).

Then, low-pass filtering is performed on the luminance signal Y input from the low thermal filtering unit 12A of the color decoder 12, and the analog / digital converter 12a converts the digital data into the memory 14 and outputs the digital data.

Similarly, the color difference signal BY (RY) transmitted from the luminance / color signal separator 11 is low-pass filtered by the low pass filtering units 12B and 12D, respectively, and is converted into digital data from the analog / digital converters 12b and 12d. The signal is converted and output to the multiplexer 13.

The multiplexer 13 then stores the multiplexer 14 in the memory 14 to increase the efficiency of the memory 14.

When the luminance signal Y and the color difference signal BY (RY) input as described above are stored and output to the digital / analog converter 15A of the signal conversion and filtering unit 15 with respect to the luminance signal Y, The original luminance signal obtained by converting it into an analog luminance signal and filtering by the low pass filtering unit 15a is output to the screen, and the demultiplexer 16 demultiplexes the color difference signal BY (RY) into the original color difference signal. The digital signal is converted into an analog signal by the digital / analog converter 15B and 15D of the signal conversion and filtering unit 15, and is filtered by the low pass filtering unit 15b and 15d and output to the screen.

At this time, the timing of each signal is adjusted in synchronization with the timing control signal generated by the timing control signal generator 17.

In the digital image processing operating as described above, if the signal stored in the memory 14 is outputted quickly or slowly according to the size ratio of the screen, the left and right sizes of the screen may be converted and configured as shown in FIG.

The size of the screen can be adjusted in the same way as described above, and the sound can be heard only when the user switches to output the voice in the same manner as in FIG. 1. The method is the same as in FIG.

That is, when the user issues a voice switching command, the microcomputer 7 checks whether the voice currently heard through the speaker is a single screen voice, and if the single screen voice is switched, the selection switch 6 is switched to output the two screen voice to the speaker. The volume value selected by the user is output to the tone controller 8.

If the voice currently heard through the speaker is not the one-screen voice, the selection switch 6 is switched to output the one-screen voice to the speaker, and the volume value selected by the user is output to the tone controller 8.

Therefore, the sound whose volume value is adjusted in the tone controller 8 is ringing through the speaker.

However, in the conventional technology as described above, when the size of one screen or two screens is changed, the voice emits the voice of the screen selected by the user to the speaker, and from one screen to two screens or from two screens to one screen. Even when the screen is changed, it is inconvenient to hear the desired screen voice only when the user switches the voice.

Accordingly, an object of the present invention is to change the size of a screen so that the user can change the voice according to the rate at which the size of one or two screens is increased without changing the voice, thereby eliminating user inconvenience. In providing.

According to the method of the present invention for achieving the above object, as shown in FIG. 8, a first step of checking whether the one-screen size ratio increases upon inputting a screen size conversion command, and the one increasing in the first step is shown. Comprising a second step of switching the selection switch after calculating the aspect ratio increase rate of the screen or two screen, and a third step of calculating the voice ratio value according to the screen increase rate after switching switching in the second step and outputs to the speaker .

Thus, the circuit configuration for performing the method consisting of each step is as shown in FIG. 1 and FIG.

When described in detail with respect to the operation and effect of the present invention configured as described above.

As shown in FIG. 7, when the TV screen is configured as a double screen, the screen width can be shifted from T1 to N by one screen, and the screen width is shifted from T1 to m by two screens.

The conversion of the screen width as described above is performed by the method shown in FIG. 5, and the audio processing at this time may be performed by the method shown in FIG.

At this time, when the user issues a command to convert the screen size, the microcomputer 7 recognizes this and first checks whether the 1 aspect ratio is increasing or the 2 aspect ratio is increasing.

As a result of the check, if the one-screen ratio is increasing, the increase ratio is calculated and then switched via the selection switch 6 so that the increased one-screen audio is output through the speaker.

Thereafter, the voice output value is calculated and output to the speaker. The speaker voice output value S is K, the screen change rate is m, and the user-selected volume value is 50%.

Similarly, if the ratio of the two screens is increasing in the above, the ratio increase of the two screens is calculated and then switched through the selection switch 6 so that the voice of the increased two screens is output through the speaker.

Thereafter, the speaker voice output value as shown in Equation (1) is calculated and output to the speaker.

For example, if the screen ratio of one screen is increased, the sound of one screen is increased by the screen increase rate through the speaker, and the sound of the two screens is relatively small and almost inaudible.

At this time, through the earphone, the voice of two screens is loud and the voice of one screen is very small and almost inaudible.

As described in detail above, the present invention has an effect of providing convenience to the user by automatically changing the voice according to the change of the screen width without changing the voice when the desired screen width is increased while watching TV. .
