Channel skipping method for protecting from erotic content in a television

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling adult broadcast channel skip in television, and in particular, when a program broadcasted on the current channel is determined to be an erotic broadcast when processing a broadcast signal on a television, the current channel is set to a skip state. The present invention relates to a method of controlling adult broadcast channel skipping in television, which can be prevented from being tuned by an up / down operation and automatically switched to the next channel so that adult broadcast programs cannot be viewed indiscriminately.

In general, as shown in FIG. 1, a television tuner unit 50 extracts only a frequency band of a channel selected by a user by tuning a radio frequency signal received through an antenna ANT from airwaves, and an input local part. An IF detector 60 for detecting an intermediate frequency from a frequency band signal of a channel tuned through the tuner unit 50 according to the oscillation signal, and an image intermediate frequency signal (i) in the signal output from the IF detector 60. P / S separator 70 for separating PIF) and SIF, and voice signal S from voice intermediate frequency signal SIF output from the P / S separator 70. An audio detector 80, an image detector 110 for separating the image signal P from the image intermediate frequency signal PIF output from the P / S separation unit 80, and the voice detector 80) and the audio signal S output from the external device 150 are selected according to the input control signal. A predetermined signal according to a selected signal input from the audio processor 90 demodulating and outputting to the outside through the speaker 100 and the image signal P output from the image detector 110 and the external device 150. After selecting, the image processor 120 separates the luminance signal and the color signal, extracts each color band from the color signal, demodulates it, and transmits the demodulated signal to the CRT driver. The image processor 120 transmits a signal corresponding to the input operation control signal. OSD (On Screen Display) 130 for outputting the information on the CRT (140) screen to overlap the screen, and various operation modes (tuning, volume control, screen control, external device mode switching of the TV) Etc.), a remote controller 20 for remotely controlling various operation modes of the television, and a remote controller for receiving a signal output from the remote controller 20 and outputting a signal accordingly. It includes a key signal input unit 30, the key panel 10 or the microcomputer 40 for controlling the configuration unit controls the overall operations of the TV according to a signal outputted from the remote control key signal input part (30).

Looking at the operation of the television in more detail as follows.

When the user selects a channel on which a quiz program or a voice multiplex program is broadcast using the key panel 10 or the remote controller 20, the microcomputer 40 tunes the tuning voltage corresponding to the channel on which the quiz program is broadcast. ) To tune to the channel where the quiz program or the voice multi-program is broadcast.

As described above, the quiz program broadcast channel tuned by the tuner unit 50 detects an intermediate frequency from the broadcast signal while passing through the IF detector 60, and passes through the P / S separation unit 70. (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 the voice signal S is detected, and the voice processor 90 undergoes a predetermined process. The image intermediate frequency signal PIF output through the speaker 100 and output from the P / S separation unit 70 passes through the image detector 34 to detect the image signal P, thereby performing the image processing unit 120. ) Is output to the CRT 140 through a predetermined process.

On the other hand, even when a viewer operates an external device 150, for example, a video cassette recorder, to reproduce the video and audio signals recorded on the video cassette tape, the viewer can view the CRT 140 and the speaker 100 through the above-described operation. Through the video and audio signals to be reproduced can be viewed.

On the other hand, these TVs are diversified in function to meet the needs of viewers, and various functions are added to satisfy the various needs of these viewers.

For example, the text mode, on the other hand, is a mode for receiving teletext, which refers to an information service for displaying text pages and images mainly composed of text information on a television monitor screen. . That is, information such as domestic and foreign news, economic industry, sports, tourism and leisure, cultural arts, life / science / women, broadcasting, and stocks are part of the TV broadcasting signal, that is, digitally encoded and inserted into the vertical return period of the video signal. Or a coded telephone signal, which is transmitted by a telephone line. The character decoder included in the television extracts the desired information from a normal television broadcast signal or from the telephone line to accumulate necessary information pages for display on a monitor. It is called teletext in the UK, video text in Germany, NHK in Japan, and antiope in France.

On the other hand, in a broadcasting system providing an extended data service (EDS), for example, KBPS (Korea Broadcasting Program System) is a data for broadcasting programs and scheduled recording on a broadcast signal, for example, a channel, a broadcast category (for example, , News, drama, sports, etc.), various program information such as broadcast start / end time and standard time data are converted into digital signals and inserted into any horizontal line during the vertical blanking interval (VBI) This signal is decoded by the KBPS decoder on the video receiving device side to perform broadcast program reservation recording function and automatic time correction function.

In addition, as a broadcasting system for providing such an EDS, there are, for example, a VPS (Video Programming System) in the UK and a European region, and a Program Delivery Control (PDC) in the UK. For example, various broadcast information data are loaded on an arbitrary horizontal line in the vertical blanking period and transmitted.

On the other hand, there are some sensational or violent broadcasting programs that limit the viewing of young children and adolescents in television broadcasting, and prevents children and adolescents from emotionally harming these adult-only programs. There was a need for a solution.

In order to solve this problem, conventionally, a lock mode (childlock) function is added to a television so that only a user who knows the password can drive the TV and use it. Since the television can be watched, even when adolescents watch educational programs and general entertainment programs that are not adult broadcasters, the parents have to enter a password to unlock the lock mode to watch TV.

Therefore, in the present invention, when the adult broadcasting code is detected using the above-described EDS data, that is, VPS / PDC data, the current channel is set to the skipped state, that is, the current channel is skipped from the channel information channel-tuned by the channel automatic tuning function. Set to to skip the current channel when the channel is up / down, and then switch to the next channel, that is, the channel where adult-only broadcasting is not performed, to prevent children or teenagers from watching adult broadcast programs indiscriminately. I found a way.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problem, and its object is to detect a current channel when an adult broadcast code is detected among VPS / PDC data inserted in an arbitrary horizontal line section within a vertical blanking period of a broadcast signal. A method of skipping adult broadcast channels on television that is set to the skip state and automatically switches to another channel that is not performing adult-only broadcasting to prevent children or teenagers from watching them indiscriminately.

An adult broadcast channel skip control method in a television according to the present invention is a television capable of receiving VPS / PDC data inserted in a predetermined horizontal line section within a vertical blanking period of a broadcast signal, wherein the television is driven on or the channel is turned on. Reading VPS / PDC data inserted into a predetermined horizontal line section within a vertical blanking period of a broadcast signal received on a currently tuned channel when it is up / down switched, and an adult among the read VPS / PDC data; Determining whether there is a broadcast code, and if the adult broadcast code is detected, set the current channel to be skipped among auto channel tuned channels so as to be skipped automatically upon channel up / down, and to the next channel among the channel tuned channels. Switching to tune and maintaining the current channel if the adult broadcast code is not detected. Characterized in that made.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings by those skilled in the art.

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

2 is a schematic block diagram of a television employed in accordance with the present invention, the configuration of which further includes a VPS / PDC detection unit 160 in a conventional television.

As shown in the figure, a television adopted according to the present invention includes a predetermined horizontal line section within a vertical blanking period of a broadcast signal output from the image detector 110 and the external device 150 by an input operation control signal. After separating the luminance signal and the color signal from the VPS / PDC detection unit 160 for detecting the VPS / PDC data inserted in the image signal P, and the image signal passing through the image detector 110, each color band in the color signal Extract the image, demodulate it, and transmit the same to the CRT 140, a key panel 10 and a remote controller 20 for selecting various operation modes, and a signal output from the remote controller 20; From the VPS / PDC detection unit 160 to control the overall operation of the television on the basis of the key signal from the remote control key signal input unit 30 and the key panel 10 or the remote control key signal input unit 30 for outputting the signal accordingly. broadcast When the VPS / PDC data is detected and applied in a predetermined horizontal line section within the vertical blanking period of the signal, if there is an adult broadcast code among the VPS / PDC data, the current channel is set to a skip state among the channel information tuned by the automatic channel tuning function. Synthesizes the OSD text signal corresponding to the control of the microcomputer 40 to the video signal applied from the image processing unit 120 and the microcomputer 40 to tune the tuner unit 50 to the next channel among the selected channel information. And an OSD (On Screen Display) unit 130 which is a character screen display means for outputting to the CRT 140.

Next, an adult broadcast channel skip control process in a television according to a preferred embodiment of the present invention will be described in detail with reference to the flowchart of FIG.

First, the microcomputer 40 is supplied with a key signal for powering on the television through the key panel 10 or the remote control key signal input unit 30 so that the television is controlled in a power-on state or based on a channel up / down key signal. It is determined whether or not this is switched (step 300).

At this time, when the TV is turned on or the channel is up / down switched, the VPS / PDC detector 160 broadcasts the program in a predetermined horizontal line section within the vertical blanking period of the broadcast signal received and applied by the tuner 50. VPS / PDC data including information, adult broadcast code, time correction data, and the like are detected and applied to the microcomputer 40 (step 302).

Next, the microcomputer 40 determines whether the adult broadcast code is included in the VPS / PDC data applied from the VPS / PDC detection unit 160 (step 304).

At this time, if the adult broadcast code is included, the microcomputer 40 sets the current channel to the skipped state among the channel information tuned automatically (step 306).

In other words, the tuning method in the UK or Europe uses a VS (Voltage Synchronizing) method, and in this tuning method, the band switching voltage corresponding to the band (VHF LOW, VHF HIGH, UHF) is changed from the reference tuning voltage. By increasing the tuning voltage in steps, channel tuning is performed by sequentially storing the tuning voltage and the band switching voltage of the channel where the broadcast signal is detected in the corresponding serial number. Therefore, the tuned channel number is allocated to the broadcasting station. It is not a unique channel number, but a sequential serial number that is tuned, so that channel information including broadcasting frequency, broadcasting channel, and broadcasting station name is transmitted on VPS / PDC data to make it easy for users to distinguish channels. Detect and store them, and users can distinguish broadcasting stations by the detected broadcasting station names. It is.

In addition, when switching channels, channel switching is possible using only the channel information tuned by the above-described automatic channel tuning function, and when the channel switching is performed, the channel information deleted through a predetermined edit mode or the channel up / down is selected. It can be set to skip when switching down.

Therefore, in step 306, the current channel is an adult-only broadcast program for which an adult broadcast code is detected, so that the channel is automatically skipped during channel up / down switching to prevent children or adolescents from watching it indiscriminately. Channel skip is set.

Next, the microcomputer 40 tunes the tuner unit 50 to the next channel in the tuned channel information, for example, the previous channel or the subsequent channel (step 308).

On the contrary, if the adult broadcast code is not included in the VPS / PDC data applied from the VPS / PDC detector 160 in step 304, the microcomputer 40 maintains the current channel (step 310).

Meanwhile, the above-described steps 302, 304 and 306 of skip setting the channel for providing the adult broadcasting are performed during automatic channel tuning to exclude the channel providing the adult broadcasting program from the channel tuning. It may be.

In addition, in order to cancel the channel skip setting based on the above-described process, a predetermined key provided in the remote controller 20 can be operated to switch to the edit mode, and the microcomputer 40 switches to the edit mode as shown in FIG. 4. Display control of the OSD screen as shown.

At this time, the user can change the skip option to NO with a predetermined key operation for the channel of the corresponding program number (PR.NO) in which the adult broadcast program is detected and the skip (SKIP) option is set to YES. When the channel information is stored by a predetermined key operation, the microcomputer 40 performs channel up / down using the edited and stored channel information, thereby allowing the user to watch the channel where the adult broadcast program is broadcast.

In addition, if the above-mentioned editing mode is prevented by a child or adolescent by accessing a predetermined password, the child or adolescent can watch a broadcast program of their own grade even without the parent, even without the parent.

On the other hand, it will be understood by those skilled in the art that various changes and modifications can be made without departing from the spirit of the present invention.

As described above, according to the present invention, when the currently received broadcast program is an adult broadcast using an adult broadcast code of VPS / PDC data, the channel is skipped in the channel information tuned by the automatic channel tuning function so that the current channel cannot be viewed. And, by automatically switching to another channel, there is an effect that children or teenagers can not watch the adult broadcast indiscriminately.
