BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a voice control method for a television having a voice multiple function and a KBPS (Korea Broadcasting Program System) decoder. It relates to a voice control method of a voice multiple broadcast.

In general, televisions with voice multi-function are used in addition to the languages in which broadcasters use certain programs (e.g. movies, news) in order to satisfy the desire of modern people to easily acquire foreign language learning through television broadcasting. Corresponding to the additional transmission of other languages, it is possible to selectively listen to the desired language in accordance with the user's request, the configuration is as shown in Figure 1 attached.

That is, the tuner unit 50 extracts only the frequency band of the channel tuned by the user by tuning the radio frequency signal received through the antenna ANT from airwaves, and the tuner unit 50 according to the local oscillation signal input. The IF detector 60 detects an intermediate frequency in the frequency band signal of the channel selected through the channel, and the image intermediate frequency signal PIF and the audio intermediate frequency signal SIF from the signal output from the IF detector 60. A voice signal is separated into a main voice and a sub-audio from a P / S splitter 70 to be separated and a voice intermediate frequency signal SIF output from the P / S splitter 70, and the received voice of the broadcast The voice detector 80 outputs information on whether or not to the microprocessor 40, and the main audio processor 90 demodulates and outputs the main audio signal and the sub-audio signal input from the voice detector 80, respectively. And the sub-audio processing unit 100 and the main voice / The audio amplifier unit 110 selectively amplifies the sub-audio / main audio + sub-audio and expresses it to the outside through the speakers 120a and 120b, and the image intermediate frequency signal output from the P / S separation unit 70 ( An image detector 130 for separating an image signal from a PIF, a luminance signal and a color signal are separated from the image signal of the image detector 130, and a color band is extracted from the color signal, and then demodulated and then demodulated. An on-screen display (OSD) unit for outputting a signal (character / graphic) necessary for controlling the operation of an input television and overlapping predetermined information on a screen of the CRT 160 by transferring the image processing unit 140 to be transmitted to 150, a KBPS decoder 170 that decodes a KBPS signal, which is one of broadcasting systems providing an extended data service, and various operation modes (tuning, volume control, screen control, external device mode switching, etc.) of the television; The key panel 10 for selecting and the above-mentioned Tel A remote controller 20 for remotely controlling various operation modes of the vision, a remote controller key signal input unit 30 for receiving a signal output from the remote controller 20 and outputting a signal corresponding thereto, and the key panel 10 or It includes a microprocessor 40 for controlling the overall operation of the television control unit according to the signal output from the remote control key signal input unit 30.

The operation of such a television is explained as follows.

When the user selects a broadcast channel using the key panel 10 or the remote controller 20, the microprocessor 40 outputs a corresponding tuning voltage to the tuner unit 50 to tune the corresponding channel. As described above, in the broadcast signal of the broadcast channel tuned by the tuner unit 50, an intermediate frequency is detected from the broadcast signal through the IF detector 60, and the voice intermediate frequency is passed through the P / S separation unit 70. The signal SIF and the image intermediate frequency signal PIF are separated.

The voice intermediate frequency signal (SIF) output from the P / S separation unit 70 passes through the voice detector 80 and is divided into a main audio signal (eg, Korean) and a sub-audio signal (eg, a foreign language). After the main audio processing unit 90 and the sub-audio processing unit 100 undergo a predetermined processing process, the main audio processing unit 90 and the sub-audio processing unit 100 output the audio processing unit 110 to the voice amplification unit 110. Then, the voice amplifier 110 selects only one of the signals input by the control signal of the microprocessor 40 (main audio / sub audio) or selects a plurality of signals (main audio + sub audio) to set the volume. Amplified by the speaker 120a, and outputs through the speaker (120a, 120b).

The control signal output to the voice amplifier 110 is output by the microprocessor 40 when the user selects the main audio mode, the sub audio mode or the multi mode through the key panel 10 or the remote controller 20. It is a signal.

In addition, the image intermediate frequency signal (PIF) output from the P / S separation unit 70 passes through the image detector 130 to detect an image signal, and the image processor 140 passes a predetermined process to perform the CRT 160. ) Is output.

Meanwhile, the television displays a menu screen for setting the function of the television, channel change information, volume change information, and input signal (RF or AV input) change information in the form of characters or figures on an image screen displayed by the CRT 160. It is equipped with OSD function, and OSD function displays the corresponding character screen on the background of the displayed image screen or displays the corresponding character screen on the blue-back image screen. This is a very useful feature to make it easy to recognize.

However, in the above-described conventional TV having a voice multiplex function, a viewer or a foreigner residing in Korea for the purpose of learning a foreign language inputs a key to select a sub-audio every time a specific voice multicast program is mainly viewed as a sub-audio. There was discomfort that should be.

Accordingly, the present invention seeks to find a way to automatically output the sub-audio to the speaker (120a, 120b) for the program that the viewer mainly views the sub-audio.

The present invention has been made to solve the above-described problems, and when the program of the tuned channel is a voice multiple broadcast, if the number of times the corresponding program is watched in the sub-audio mode for a predetermined period is more than the reference value, it automatically switches to the sub-audio mode. It is an object of the present invention to provide a voice control method of a voice multiple broadcast.

If not stored in the internal memory, reading the negative count value of the program from the internal memory, determining whether the negative count value is greater than the reference value, and the negative count value is greater than the reference value. If it is large, the process of automatically switching to sub-negative, and if the sub-count count value is less than the reference value characterized in that the process of waiting for the control of the viewer.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The configuration of the television employed in the embodiment of the present invention is the same as that of a voice multi-function television having a decoder of KBPS, which is one of the broadcasting systems for providing the extended data service of FIG.

That is, the key panel 10, the remote controller 20, the remote controller key signal input unit 30, the microprocessor 40, the tuner unit 50, the IF detector 60, the P / S separator 70, and the voice. The detector 80, the main / sub audio processor 90 and 100, the audio amplifier 110, the speaker 120a and 120b, the image detector 130, and the image processor 140 and the OSD unit 150. , CRT 160 and KBPS decoder 170.

In such a configuration, the key panel 10 or the remote controller 20 is an input means for operating the television, and includes a volume up / down key for volume control and a predetermined key (menu key, image quality control key, Remote control unit 20 having a plurality of keys including a direction key, a number key), a key for sound quality setting, and a key for image quality setting, and outputs a key signal corresponding to a user's key operation, and is typically remotely inputable. A key signal corresponding to a key operation is transmitted on an infrared carrier using a remote controller, and the remote controller key signal input unit 30 provided in the television body demodulates, detects, and amplifies the received infrared carrier to be described later. Is applied.

The microprocessor 40 controls the overall operation of the television based on the key signal from the key panel 10 or the remote controller 20. In particular, the microprocessor 40 broadcasts the program identification code detected by the KBPS decoder 170 and the voice multiple times. Based on the sub-audio mode viewing count value of the program for a certain period of time, when the audio multiple program is watched as a sub-voice more than a certain number of times, the sub-audio mode is automatically switched.

The tuner unit 50 outputs a broadcast signal received by being tuned to a channel corresponding to the control of the microprocessor 40.

Meanwhile, the main audio processing unit 90 and the sub audio processing unit 100 are received by the tuner unit 50 and applied through the IF detector 60, the P / S separation unit 70, and the voice detector 80. The main voice and the sub-audio are respectively output to the voice amplifier 110, and the voice amplifier 110 selects one of the main voice mode, the sub-voice mode, and the multi-mode by the control signal of the microprocessor 40, Amplifies the audio signal to a predetermined volume and outputs it to the loudspeakers 120a and 120b.

At this time, in the multi mode, the main voice and the sub voice are output at the same time. For example, the main voice is output to the right speaker and the sub voice to the left speaker.

The image processor 140 processes the image signal received from the tuner unit 50 and applied through the IF detector 60, the P / S separation unit 70, and the image detector 130 into a displayable signal, thereby providing a CRT. Output to 160.

In addition, the OSD unit 150 is a character screen display means for synthesizing an OSD text signal corresponding to the control of the microprocessor 40 to an image signal output from the image processor 140 and outputting the synthesized OSD text signal to the CRT 160. But not the timing unit that determines the horizontal / vertical position of the OSD, the character ROM to save and export the OSD text font, the ROM to store the program to control the OSD text display, and the program to control the OSD text display control. And a display generator for outputting an RGB signal for displaying OSD characters and a vertical blanking signal based on a control signal for OSD character size conversion and OSD character type selection from the microprocessor 40.

The KBPS decoder 170 extracts data added to the broadcast signal received from the tuner 50 and outputs the data to the microprocessor 40.

The KBPS decoder 170 is a component that decodes a KBPS signal, which is one of broadcast systems providing an extended data service. In addition, KBPS digitally records data for broadcast programs and scheduled recording, such as channels, program genres (eg, news, drama, sports, etc.), broadcast start / end times, audience ratings, and standard time data on broadcast signals. By converting the signal into an arbitrary horizontal line during the vertical blanking interval (VBI), the signal is decoded by a KBPS decoder on the image receiving device side to perform a broadcast program reservation recording function, and the like. To help.

Next, a description will be given in detail with reference to the flowcharts of FIGS. 2A and 2B attached to the audio output process of the voice multiple broadcast in the television according to the preferred embodiment of the present invention in the television having the above-described configuration.

When the viewer selects a desired channel, the microprocessor 40 outputs a control signal to each component so that the viewer can watch the broadcast of the corresponding channel.

In this case, in the case of the voice multiple broadcast, in order to control the voice signal output to the speakers 120a and 120b, it is first determined whether the broadcast received from the data input from the voice detector 80 is the voice multiple broadcast (S100).

If the received broadcast is voice multiplexed, as shown in FIG. 2B, the date / day information in the memory is read in order to determine the time when the sub-negative count value (SCNT) is to be cleared (e.g., the first day of the month / every Monday). It is determined whether the date / day is a clear time, and if the corresponding time is cleared, the negative voice count value is cleared (S110). That is, the sub negative count value (SCNT) is cleared with a certain period (1 month / 1 week).

Subsequently, the identification code of the program being viewed is found from the information detected by the KBPS decoder 170, and it is searched whether the identification code of the corresponding program is already stored in the memory (S120).

If the identification code of the program being watched is recognized for the first time, that is, if the identification code is not stored in the memory, it is stored in the memory and the negative count value (SCNT) is set to "0", and the identification code is already stored. If so, the negative voice count value (SCNT) of the corresponding program is read (S130 and S140).

It is determined whether the negative negative count value SCNT is greater than a reference value (eg, 5) (S150).

If the determination result is greater than the reference value, the voice mode of the program being watched is automatically switched to the sub-voice mode (S160).

Therefore, the voice amplifier 110 amplifies only the voice signal input from the sub-voice processor 100 according to the control signal of the microprocessor 40 and outputs the same to the speakers 120a and 120b. In other words, when the viewer watches the program being watched for more than a certain number of times, the viewer automatically switches to the sub-audio mode even if the viewer does not select the sub-audio mode.

On the other hand, if the negative count value SCNT is less than or equal to the reference value as a result of the determination in step S150, the user waits for the voice control of the viewer, and if the negative mode is selected, switches to the negative mode and then the value of the negative counter of the corresponding program (SCNT). When 1) is increased and the multi mode is selected, the multi-mode is switched to output the main voice and the sub voice separated by the right speaker and the left speaker, respectively (S170 to S210).

As described above, in the present invention, after watching a specific voice multicast program in the sub-audio mode more than a predetermined number of times during the predetermined period, the present invention automatically switches to the sub-audio mode at the time of viewing the program, so that the viewer inputs a key for selecting the sub-audio mode. There is no need to do this has the effect of providing convenience to the user.

While the invention has been shown and described with respect to particular embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention as set forth in the claims. Anyone can see it easily.
