METHOD AND APPARATUS FOR CONTROLLING THE RESTRICTION OF WATCHING TELEVISION IN CLOSED CAPTION BROADCASTING PROGRAM}

The present invention relates to caption broadcasting, and more particularly, to a method and apparatus for controlling parental control of a caption broadcasting program by dividing a caption level of a broadcast program and determining whether to display the caption.

In general, a program rating system is typically applied to a technology for restricting viewing of a broadcast program.

The program rating system determines a rating for each broadcast program as shown in FIG.

That is, the program rating system determines the rating in one broadcast program unit.

Therefore, in the related art, as shown in FIG. 2, when the grade of a broadcast program is determined based on the program grade as shown in FIG. 1 and the grade signal and the broadcast program are transmitted together, the grade of the broadcast program is displayed on the screen of the receiver. This is a concept of informing the viewers of the restriction of viewing of a broadcast program.

That is, in the related art, as shown in FIG. 2, a receiver may receive a rating signal of a broadcast program transmitted together with a broadcast program signal and display a rating of the broadcast program on a screen or restrict viewing.

However, the related art has a problem in that it is necessary to limit the viewing of the entire program to the viewing restriction target by simply giving only one grade in program units.

Therefore, in order to improve the conventional problem, the present invention assigns each rating to subtitles inserted in the middle of a broadcast program, and detects the rating for each subtitle according to the progress or reproduction of the program, thereby making the scene unsuitable for the viewer. It is an object of the present invention to provide a method and apparatus for controlling parental control of a closed captioning program which is designed to restrict viewing of a program only when an ambassador appears.

That is, in the present invention, only a part of the scenes of some scenes have a problem and the rest of the scenes do not have a problem in that the part where viewing should be restricted is not selectively played.

According to the present invention, when capturing a video object for a broadcasting medium or a recording medium, the caption level of the caption synchronized with the audio of the program is determined, and the rating signal is inserted into the program together with the caption signal, thereby limiting the audience to use the caption level. The present disclosure may provide a method and apparatus for notifying or performing parental control to achieve the object.

That is, according to the present invention, a process of determining a subtitle rating by referring to subtitle rating reference data preset in transmitting and reproducing a subtitle signal synchronized with a voice of a program in a video or audio signal and transmitting the same to a reproduction medium or a broadcast medium. And transmitting the determined rating signal together with the caption signal in a video or audio signal of the program, and determining whether viewing is restricted for all or part of the program by reading the transmitted rating signal. It provides a method and apparatus for performing.

To this end, the present invention performs the following operation.

First, a rating is given for each subtitle of a program.

That is, when a subtitle signal synchronized with voice is inserted when a program is produced, a rating is given for each subtitle according to a predetermined standard.

In this case, the level of the caption may be given to be constant or continuously changed according to the broadcast progress or reproduction of the program.

Thereafter, the caption class signal is transmitted to the broadcast medium or stored in the recording medium together with the caption signal.

That is, the grade signal once given to the caption is stored together with the caption signal when broadcast with the caption signal or stored in the video recording medium for reproduction.

At this time, the grade signal is recorded before the subtitle signal synchronized with the voice so that the grade of the subtitle to be displayed afterwards is decoded.

Accordingly, when the broadcast signal or the signal stored in the recording medium is reproduced, the subtitle rating signal is separated and decoded to determine the subtitle rating to determine whether to display the subtitle.

Accordingly, by determining the rating of the subtitles, 1) before the subtitles are displayed, the parental level is first determined by displaying the parental level on the screen. In one case, it can be implemented to selectively limit the viewing of the program.

However, when the subtitle level below the set level is again determined after the parental level operation is performed, the parental level operation is released.

In the above, the viewing restriction of the program may be implemented to block transmission of the program itself to the playback device or to skip only a corresponding part thereof.

Hereinafter, the present invention will be described in detail with reference to the drawings.

3 is a block diagram illustrating a process of assigning a rating signal to a caption according to an exemplary embodiment of the present invention. As shown in FIG. 3, the caption signal generator 201 generates a caption signal synchronized with voice according to voice information of a broadcast program. And a caption rating determiner 202 for determining a rating of the caption signal generated by the caption signal generator 201 with reference to caption rating reference data, a video and audio signal of a broadcast program, and the caption signal generator ( And a signal synthesizer 203 for synthesizing the subtitle signal at 201 and the subtitle rating signal at the subtitle rating determiner 202 and transmitting it to the broadcast medium 204 or the recording medium 205.

6 is a block diagram showing a parental control process using a subtitle rating signal according to an embodiment of the present invention. As shown in FIG. 6, an antenna 211 for receiving a broadcast program, a player 212 for reproducing a recorded program, and Caption for determining whether to restrict viewing by separating and decoding a caption rating signal from a reception broadcast program at the antenna 211 or a playback program at the player 212 and comparing it with the parental level reference data set by a user. A rating program 213 and a reception program in the antenna 211 transmitted to the program viewing device 215 or reproduction in the player 212 when the subtitle rating judging unit 213 determines that viewing is restricted. A parental control unit 214 blocks the program.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

First, in the present invention, when producing a broadcast program, the caption signal generator 201 that receives voice information generates a caption signal synchronized with the voice.

At this time, the subtitle rating determiner 202 compares the subtitle signal generated by the subtitle signal generation unit 201 with preset subtitle rating reference data to determine the level of the subtitle, and then applies the rated signal at that time to the signal synthesizer 203. )

Accordingly, the signal synthesizer 203 synthesizes the video and audio signals, the caption signal, and the caption level signal, and transmits them to the broadcast medium 204 or the recording medium 205.

Here, the signal synthesizer 203 synthesizes and transmits a caption grade signal to a video signal or an audio signal in the case of analog broadcasting, and transmits the video using a video signal, an audio signal or a separate data channel in the case of digital broadcasting.

Therefore, the program produced as described above may be transmitted for broadcasting or stored in a recording medium for reproduction.

The rating signal of the subtitle generated when the program is produced may be changed in time, or may keep the same rating from beginning to end.

4 is an exemplary diagram illustrating a case where a subtitle rating is divided into three stages.

When the subtitles included in the program are determined by the subtitle rating as illustrated in FIG. 4, an example of the subtitles that change in time according to the subtitles in one program is shown in FIG. 5.

That is, FIG. 5 shows an example of changing the actual subtitle rating so that the subtitle level is changed in one program as the broadcast or playback time changes, so that only the part that needs to be restricted can be selected and notified to the receiver. to be.

Accordingly, when the caption level is assigned as shown in the example of FIG. 5, the receiving side can realize the parental control operation in more various ways by using the caption level signal.

A process for effectively restricting the viewing restriction target of a program using a rating signal of a caption is shown in the block diagram of FIG.

FIG. 7 is a signal flowchart for a parental control operation when reproducing a program whose subtitles are rated as shown in FIG. 5.

In the present invention, it is assumed that the viewer is 12 years old and the viewable portion of the 15 year old grade or higher is set such that viewing is restricted.

First, when a broadcast program is received through the antenna 211 or a program is played in the player 212, the subtitle rating determiner 213 separates and decodes a subtitle rating signal so that the user can view the preset parental level reference data. Will be compared.

If the rating of the current subtitle to be displayed is higher than the preset parental control level, for example, when it is determined that the user can watch at least 15 years old, the subtitle rating determination unit 213 controls the parental control unit 214 to receive it. The parental control function is operated so that the broadcast program or the reproduced program is not transmitted to the program viewing device 215.

In addition, when the rating of the subtitle to be displayed is lower than the preset parental control level, for example, when it is determined that the user can view the video over 10 years old, the subtitle rating determination unit 213 controls the parental control function of the parental control unit 214. Does not work.

Accordingly, the 12-year-old viewer is watching only the program of the remaining part except for the part that can be viewed over 15 years old as shown in FIG.

If the rating of the subtitle to be currently displayed is higher than the preset reference level, the viewing limiter 214 does not transmit any signal to the program viewing device 215, but transmits another pre-stored video, audio, video and Subtitles may be selectively transmitted or skipped.

The above-described parental control function will be described with reference to the signal flowchart of FIG.

First, when a broadcast program is received or when a program recorded on a recording medium is played back, the caption rating unit 213 determines whether there is a caption rating signal in the program.

At this time, if there is a caption rating signal, the caption rating determiner 213 determines whether the parental level is set.

Here, it is assumed that the parental control level is set to be impossible to view at least 15 years old and the viewer is 12 years old.

Accordingly, when the parental level is set, the caption rating determiner 213 determines whether the level of the caption to be displayed is equal to or greater than the parental level preset by the user.

If the rating of the subtitle to be currently displayed is determined to be greater than or equal to the preset parental level, that is, if the rating of the subtitle to be displayed is determined to be a viewable level of 15 or older, the caption rating determination unit 213 may include a parental control unit ( In operation 214, the parental control function is activated so that the currently playing program is not transmitted to the program viewing device 215.

When the subtitle rating to be displayed is lower than the preset parental level, that is, the subtitle rating determination unit 213 determines the current subtitle rating to be 10 or older. The parental control function of the parental control unit 214 is not operated to transmit to the parental device 215.

As described in detail above, the present invention provides a rating for each subtitle within a program when the program is produced, and enables viewers, especially children, to restrict viewing depending on the rating for each subtitle in the program during broadcasting or playback of the program. There is an effect that allows you to watch the program except for some harmful content.

Therefore, the present invention can be applied to all fields for playing back images to effectively block the viewing object.
