TV transceiver and control method for selective control of minor TV viewing

The present invention relates to a TV transceiver for controlling a minor TV viewing to prevent a minor from viewing a program that cannot be viewed by a minor, and a control method thereof. In particular, the present invention provides a simple display of a minor non-viewable display signal from a received TV video signal. The present invention relates to a TV transceiver and a control method for selecting and controlling a minor TV viewing, which enables the TV receiver to identify that the program being broadcast is a program that cannot be viewed by a minor, so that the TV receiver can be displayed only when an ID signal is input from the outside.

With the flood of video media like this, public opinion about the regulation of violence, sensational scenes and contents is rising.

This trend is embodied in North America (US, Canada), where technology and measures are being implemented to remove unhealthy images of violence and indecentness from home.

This is an integrated circuit called a V chip (Violence Chip).

This is a system that prevents the video from appearing on TV screens when it receives images that you do not want to show to young children.

In Korea, such a system does not use the North American system, but a simple warning message (18 in the right corner) The program is sent from start to finish so that it appears on the receiving screen.

Looking at the technical configuration and the operation according to the operation as described above are as follows.

The image processing unit 110 converts and outputs the power, which can be driven by the Citi 114, and the Citi drive 112 for displaying a signal provided by the image processing unit 110 to the Citi, and the tuner ( A voice detector 109 for separating and outputting an audio signal from the intermediate frequency signal output from the 107, and a voice processor 111 for converting the voice signal into a voice signal synchronized with an output image to the speaker 113 and outputting the voice signal. It is composed of

In addition, a block diagram of a conventional V-chip TV transceiver includes a video encoder 201 that encodes and outputs an image to be photographed by a camera, and a signal format promised by the TV receiver. A V chip encoder 202 for multiplexing and outputting the program grade information by using a part of the vertical blanking section of the video signal, an audio encoder 205 for encoding and outputting audio for the image taken by the camera, and Mixer 203 for mixing the video output from the V chip encoder 202 and the audio output from the audio encoder 205 to convert the RF signal according to the broadcast standard to transmit through a transmission antenna, and through the transmission antenna A tuner 207 that receives the transmitted RF signal through a receiving antenna and converts the signal into a channel selection and an intermediate frequency signal and outputs the tuner 207; When the video signal is detected from the intermediate frequency signal and detected, the video detector 208 separates and outputs the composite video signal for processing the image, and converts the separated composite video signal into a signal for display on a TV screen. The V chip decoder 215 which finds program grade information from the image processor 210 and the image signal output from the image detector 208, and compares the grade information of a pre-entered consumer. And the image controller 216 and the Citi 214 that control the image provided by the image processor 210 according to a program level according to the control signal output from the V chip decoder 215. From the Citi drive unit 212 and the intermediate frequency signal output from the tuner 207 to generate a power, and to display the signal provided by the image controller 216 to the Citi And an audio detector 209, which outputs to separate satellite signals, wherein the audio signal comprises a speech processing unit 211 to switch the output to the output video and synchronized audio signal to the speaker 213.

Referring to the prior art configured as described above in detail.

The video encoder 101 encodes an image taken by a camera of a broadcasting station according to the TV transmitter's standard and outputs the image to the image editing unit 102.

Accordingly, the video editing unit 102 distinguishes a minor viewing impaired program so that a non-viewing program displays a warning message (a form in which the number 18 is cheap) on a part of the TV screen, and displays a warning message on the video encoder 101. It is multiplexed to the video signal of and supplied to the mixer 103.

At this time, the audio encoder 105 encodes the audio for the image taken by the camera of the broadcasting station and supplies it to the mixer 103.

Then, the mixer 103 mixes the video output from the image editing unit 102 and the audio output from the audio encoder 105 and converts the converted audio signal into an RF signal conforming to the broadcast standard, and transmits the converted RF signal to the transmission antenna 104. To the TV receiver.

After the transmitted signal passes through the TV receiver, a warning message is displayed on a part of the screen on the TV screen 115.

Looking at the display process, the receiving antenna 106 receives the RF transmitted from the transmitter and supplies it to the tuner 107.

The tuner 107 converts the channel tuner and the intermediate frequency signal into an image detector 108 and an audio detector 109, respectively.

Then, the image detector 108 detects the image signal from the intermediate frequency signal, separates the baseband composite image signal for image processing, and outputs the image signal to the image processor 110 and the V chip decoder 115, and the voice detector. Reference numeral 109 divides the voice signal from the intermediate frequency signal, converts the voice signal into a baseband voice signal, and outputs the voice signal to the voice processor 111.

The image processor 110 converts the baseband composite image signal into a signal (R.G.B signal, horizontal and vertical synchronization signals, etc.) for displaying on the TV screen and sends the signal to the Citiity driver 112.

Accordingly, the Citiity driver 112 generates power to drive the Citi 114 and displays the signal provided by the image processor 110 on the Citi 114.

Meanwhile, the voice processor 111 outputs the baseband voice signal provided by the voice detector 109 to the speaker 113.

In this manner, when an image is displayed on the TV screen, a warning message indicating that the child cannot be viewed is displayed on a part of the screen.

2, the video encoder 201 encodes an image taken by a camera of a broadcasting station according to the TV transmitter's standard and outputs the video to the V chip encoder 202.

Accordingly, the V chip encoder 202 multiplexes information on program grades promised to each other on the broadcast side and the receiver side in a vertical blanking section in which the video signal is not loaded among the composite video signals and outputs the result to the mixer 203. .

At this time, the audio encoder 205 encodes the audio for the image taken by the camera of the broadcasting station and supplies it to the mixer 203.

The mixer 203 synthesizes the video output from the V chip encoder 202 and the audio output from the audio encoder 205 and converts the image into an RF signal conforming to the broadcast standard and transmits the result to a receiver through a transmission antenna.

Then, when the receiving antenna of the receiving side is received and provided to the tuner 207, the tuner 207 tunes a channel to be tuned, converts the tuned RF signal into an intermediate frequency signal, and the image detector 208 It outputs to the audio | voice detection part 209, respectively.

The image detector 208 detects the image signal from the intermediate frequency signal provided by the tuner 207, and separates the baseband composite image signal for image processing to the V chip decoder 215 and the image processor 210. Each voice detector 209 detects a voice signal among the intermediate frequency signals provided by the tuner 207, and separates the baseband voice signal and outputs the voice signal to the voice processor 211.

Accordingly, the image processor 210 converts the input baseband composite video signal into a signal for displaying on a TV screen and outputs the signal to the image controller 216. The voice processor 211 converts the received baseband audio signal into a speaker. The signal 113 is converted into an audio signal capable of driving the signal 113 so that a signal synchronized with the output image is output to the speaker 113.

In this case, the V chip decoder 215 finds program grade information multiplexed in the vertical blank period of the composite video signal output from the image detector 208.

When the program rating information thus found is compared with the rating information of the pre-entered consumer, and judged as a program that cannot be viewed by a minor, a control signal for preventing an image from being displayed is output to the image controller 216.

Accordingly, the image controller 216 does not provide the image driver 212 to the image signal so that the image is not displayed when the control signal for preventing the display is provided by the V chip decoder 215.

Then, the Citiity driver 212 does not drive the Citiity 214.

However, in the prior art as described above, the warning message currently being sent by domestic broadcasts is only a warning, so that the minor can watch at any time if he or she minds, so it is too weak to prevent the minor from watching TV, North American V chip Compared to the above, there is no standard for program grade in Korea, and the signal procedure is complicated, which is a great burden for both the transmitting side and the receiving side.

Therefore, an object of the present invention for solving the conventional problems as described above is to allow the minor to be viewed only when there is a specific ID signal to protect the minor from unhealthy scenes such as violence, pornography, etc. To provide a TV transceiver for controlling selection and a control method thereof.

Another object of the present invention is to transmit the current warning message in the broadcasting station without multiplexing the transmitter but multiplexing the broadcast signal, and if the receiver simply finds the warning message in the broadcast signal, it does not output the video and audio currently input. The present invention provides a TV transmitting and receiving device and a control method thereof for selectively controlling a minor TV viewing so as to output a video and an audio so as to prevent a minor from watching violent material, a sensational scene, and the like.

FIG. 7 is a flowchart illustrating a method for controlling a TV transceiver for selecting and controlling a minor's TV viewing according to the present invention. As shown in the drawing, a first message for checking whether there is a warning message from a composite video signal detected from an image and a voice is shown. Step S702, and if there is no warning message in the first step (S702), the second step (S703) to check whether the consumer password is registered if there is a warning message without the video and audio control, and the second step ( If the password is registered in S703, the third step (S704) (S707) of outputting the currently received video and audio without performing the video and audio control, and if the password is not registered in the second step (S703) A fourth step (S705) 706 is performed to output the video and audio for warning message without outputting the video and audio currently input.

Referring to the operation and effect of the present invention configured as described in detail as follows.

The video encoder 101 of the transmitter 300 encodes an image taken by a camera of a broadcasting station in accordance with the TV transmitter's standard and outputs the image to the image editing unit 102.

Accordingly, the video editing unit 102 distinguishes a minor viewing impaired program so that a non-viewing program displays a warning message (a form in which the number 18 is cheap) on a part of the TV screen, and displays a warning message on the video encoder 101. It is multiplexed to the video signal of and supplied to the mixer 103.

At this time, the audio encoder 105 encodes the audio for the image taken by the camera of the broadcasting station and supplies it to the mixer 103.

Then, the mixer 103 mixes the video output from the image editing unit 102 and the audio output from the audio encoder 105 and converts the converted audio signal into an RF signal conforming to the broadcast standard, and transmits the converted RF signal to the transmission antenna 104. To the TV receiver.

Then, the tuner 302 of the TV receiver tunes a channel among the RF signals received through the reception antenna 301, converts the RF signal for the tuned channel into an intermediate frequency signal, and detects the image detector 303 and voice. Output to section 311, respectively.

The image detector 303 detects the image signal from the intermediate frequency signal, separates the composite image signal therefrom, and outputs the composite image signal to the image recognition unit 304 and the image processor 305, respectively.

The image processor 305 converts the composite image signal output from the image detector 303 into a signal that can be displayed on the Citi 310 and outputs the signal to the image controller 306, and the image recognizer 304 In the composite video signal output from the image detector 303, a warning message (for example, 18) is found in a section in which a warning message is found, and it is compared with the contents stored in the memory in advance to determine whether there is a warning message. Determination is made and sent to the microcomputer 307.

In this case, when the voice detector 311 detects a voice signal from the intermediate frequency signal output from the tuner 302 and outputs the voice signal to the voice processor 312, the voice processor 312 outputs the voice signal to the speaker 315. The signal is converted into a possible signal and output to the voice controller 313.

The microcomputer 307 analyzes a signal output from the image recognition unit 304 and a secret key registered by the consumer in advance.

As a result of analysis, if there is no warning message, the microcomputer 307 sends a signal not to control the video control unit 306 and the voice control unit 313, and the video message output unit 308 and the voice message output unit 314 Send a control signal that does not operate.

Then, the image controller 306 transmits the image signal processed by the image processor 305 to the Citiity driver 309 to display the image transmitted from the transmitter 300 on the Citi 310, the voice control unit 313 outputs the voice signal processed by the voice processor 312 to the speaker 315.

If there is a warning message, the microcomputer 307 determines whether the password of the consumer is registered, and if so, displays the current received signal on the screen without controlling the video and audio, such as when there is no warning message. If the password is not registered, a signal for controlling the video control unit 306 and the voice control unit 313 is transmitted, and a control signal for operating the video message output unit 308 and the voice message output unit 314 is transmitted.

Then, the image controller 306 operates to prevent the image signal processed by the image processor 305 from being transmitted to the Citiity driver 309, and the voice controller 313 receives the audio signal processed by the voice processor 312. It is not transmitted to the speaker 315.

At this time, the video message output unit 308 outputs a pre-stored video message to the Citiity driver 309, and the voice message output unit 314 is a pre-stored voice message, for example, the current program is viewed by a minor. Since it is a non-program, a command for selecting another channel is output to the speaker 315.

The Citiity driver 309 outputs a separate image output from the video message output unit 308 to the Citi 310 to be displayed.

In the case of violence or sensational scenes as described above, minors are not allowed to watch, and in the case of non-minor, they can be viewed only when a password of a pre-registered consumer is input.

Referring to FIG. 4, the operation of the image recognition unit 304 outputs a composite image signal separated by the image detection unit 303, and then synchronizes and clocks the generation unit of the image recognition unit 304. 401 and data slicer 404 are input.

The synchronous separation and clock generator 401 separates the horizontal synchronous signal and the vertical synchronous signal from the composite video signal, and also generates a clock signal that is synchronized with the video signal. The data slicer 404 and the horizontal and vertical timing unit ( 402).

Then, the vertical and horizontal timing unit 402 generates a timing signal for determining the vertical and horizontal positions from the image signal using the horizontal synchronous signal, the vertical synchronous signal, and the clock signal to the horizontal and vertical position designator 403. When outputting, the horizontal and vertical position designation unit 403 receives a signal (start and end points of horizontal and vertical positions) for recognizing an image section (alert message section) determined using the timing signal. To occur).

At this time, the data slicer 404 slices the composite video signal output from the image detector 303 for each predetermined level of the clock output from the synchronization separation and clock generator 401, and thus the data of "0" or "1". And output the data to the data comparator 405.

Accordingly, the data comparator 405 takes only the value of the section designated by the horizontal and vertical position designation unit 403 among the digital data values output from the data slicer 404 and outputs the data output from the memory 406 (that is, for a warning message). Digital data) and outputs the result to the microcomputer 307.

The memory 406 analyzes the warning message sent from a broadcasting station in advance to determine whether there is a warning message among the input video signals, and stores the digital message as a digital data value according to the system of the present invention. The data value is output whenever there is a data output request.

Then, referring to the process of setting the warning message section based on Figure 5, in the horizontal and vertical timing unit 402 and the horizontal and vertical positioning unit 403 of Figure 4 first start point (C time) and end point ( D time) and set the start point (A time) and the end point (B time) horizontally.

6 illustrates an example of binary data shapes of the data slicer 404 and the memory 406 of FIG. 4. O, 1,8 Shows binary data when the data slicer 404 sampled 5 clocks vertically and 7 lines horizontally.

Such binary data is also stored in the memory 406.

Referring to the process of FIG. 7 again based on the operation process of FIG. 7, the image detection is carried out from the input intermediate frequency signal first (S701).

If there is a video signal, the composite video signal is separated therefrom and output.

Then, it is checked whether or not there is a warning message among the separated composite video signals (S702).

As a result of the check, if there is no warning message, video and audio control is not performed (S704). If there is a warning message, it is checked whether the consumer's password is registered. (S703)

If the consumer's password is registered in the above, without video and audio control, and outputs the video and audio currently input to the TV antenna (S704),

If the consumer's password is not registered, the video and audio control is performed to output the video and audio input through the current reception antenna (S705). Instead, the video and audio for the pre-stored warning message are output. (S706) (S707)

As a result, if there is a warning message in the broadcast signal, it controls the actual video and audio so that the minor cannot watch.

Therefore, in the present invention, when a broadcast station multiplexes the current warning message without transmitting a transmitter using the current broadcast system and multiplexes the broadcast signal, the receiver simply finds the warning message in the broadcast signal and does not output the current video and audio. In addition, it is possible to output a warning message video and audio so that the inexperienced minors can not watch the violence, sensational scenes and the like.
