The present invention relates to a method of executing a parental lock, for example, an image inappropriate for adolescents or children to watch in various types of video devices such as a DVD-Recorder or a digital television (D-TV). The present invention relates to a method of executing a parental lock to prevent unauthorized display of the screen.

Generally, a DVD recorder capable of recording or playing back high quality video data and high quality audio data for a long time, and a digital television for outputting and displaying broadcast programs received through digital broadcasting as high quality video and high quality audio, etc. Types of video equipment have been developed and released and are commercially available.

On the other hand, the video device is equipped with a parental lock function to prevent the display of adult images that are inappropriate for adolescents or children to watch, for example, in the DVD recorder, when the optical disk is inserted into the device, The audience rating information is searched among the navigation information recorded in the lead-in area of the optical disc.

In the DVD recorder, the parental level that the user selects and designates is stored and managed in the device. When the parental level detected in the navigation information is equal to or greater than the parental level stored and managed in the device, for example, the parental level is viewed. If the rating is 19 years old or more and the parental level is set to 15 years old or younger, even if the corresponding program or title is requested to be played, a series of procedures for requesting and confirming a password input are performed without being played as it is.

Accordingly, it is possible to prevent unauthorized display of images inappropriate for adolescents or children to watch, and in the case of digital television, electronic program guide (EPG) information provided as additional service information through digital broadcasting. By referring to the search, a series of parental lock functions are performed to prevent adolescents or children from tuning into a specific broadcast channel on which an adult program is broadcast.

However, when the viewing grade information is not separately recorded in the navigation information of the optical disc or when the viewing grade information is not included in the EPG information, the parent lock function as described above may be performed. There is a problem that can not be, so that adolescents or children can watch the adult program or title.

Accordingly, the present invention was created to solve the above problems, and for example, in various types of video devices such as a DVD-recorder or a digital television (D-TV), a specific portion within a video frame may be used. It is an object of the present invention to provide a method of executing a parent lock which detects a displayed parental level, compares it with a preset parental level in the apparatus, and selectively outputs and displays a video frame according to the comparison result.

In accordance with another aspect of the present invention, there is provided a method of executing a parental lock, comprising: performing a selective scan on a specific portion of a video frame to detect a rating; And comparing the detected parental level with a preset parental level in the device, and selectively outputting and displaying the video frame.

In addition, the first step is to scan the specific portion in the video frame to detect the age indication mark indicating the viewing rating, and the second step is when the detected viewing rating is more than the preset parental level in the device The control method is such that the video frame is not output.

Hereinafter, a preferred embodiment of a method for executing a parental lock according to the present invention will be described in detail with reference to the accompanying drawings.

First, the present invention can be applied to various types of video devices such as a DVD recorder or a digital television. For example, in the DVD recorder to which the present invention is applied, as shown in FIG. 1, an optical disc 10 and an optical pickup. (11), a video disc record (VDR) system 12, a microcomputer 13, an OSD generator 14, a mark detector 15, a memory 16, and the like.

Meanwhile, the mark detector 15 performs a selective scan of a specific part in a video frame reproduced and signal-processed by the VDR system 12. For example, as shown in FIG. As described above, an age indication mark (eg, '19') for indicating a rating may be displayed on the upper right portion of the video frame.

In addition, when performing the parental lock function according to the operation control of the microcomputer 13, the mark detection unit 15 selectively scans an upper right portion of the video frame to detect an age indication mark. The microcomputer 13 compares the viewing grade identified by the age display mark with the viewing restriction grade previously stored and managed in the memory 16.

In addition, when the viewing grade detected by the mark detection unit 15 is equal to or greater than the parental level previously stored and managed in the memory 16, for example, the parental level is 19 or more, and the parental level is 15 or less. If it is set to, the operation of the VDR system 12 is controlled so that the video frame is not output, thereby preventing the display of an inappropriate image for adolescents or children to watch. Same as

3 is a flowchart illustrating an operation of a method for executing a parental lock according to the present invention. For example, in the microcomputer 13, when the optical disc 10 is inserted and seated in the device, the lead-in of the optical disc is inserted. After reading the navigation information recorded in the (Lead-In) area, downloading the navigation information into the memory 16, searching the navigation information, and performing a series of reproduction operations requested by the user (S10).

On the other hand, in the VDR system 12, a title or a recording program recorded on the optical disc 10 is reproduced and signal processed according to the operation control of the microcomputer 13, and a video frame (Video) Frame) (S11), the microcomputer 13, if the current parental lock mode (Parental Lock Mode) is not set (S12), the generated video frame is normally output (s13) ).

On the other hand, when the current lock mode is set in the microcomputer 13, the mark detection unit 15 is operated to be controlled. In the mark detection unit 15, as described above, the generated video is controlled. The upper right portion of the frame is selectively scanned to detect an age indication mark as a viewing grade (S14).

The microcomputer 13 compares the viewing grade detected by the age indication mark with the viewing restriction grade previously stored and managed in the memory 16. For example, the mark detection unit 15 If the parental level detected by) is less than the parental level that is pre-stored and managed in the memory 16 or if the parental level is not detected separately, the generated video frame is normally output.

On the other hand, when the parental level detected by the mark detection unit 15 is greater than or equal to the parental control level previously stored and managed in the memory 16 (S15), for example, the parental level is 19 years old or more, When it is set to 15 years old or younger, the microcomputer 13 operates the VDR system 12 to control the video frame not to be output.

For example, as shown in FIG. 4, while the adult video frames are being played, the previously output video frame is repeatedly output (S16), thereby preventing the display of the video frame that is inappropriate for viewing by adolescents or children. Done.

In addition, the microcomputer 13 performs the above-described series of parental lock functions repeatedly until the playback operation is terminated (S17), and then performs an arbitrary operation corresponding to the user's request ( S18).

For reference, the microcomputer 13 outputs a no-signal image or forcibly stops the playback operation while the adult video frame is reproduced as described above, so that the title or recording program including the adult video frame is played. It can be prevented at the source.
