The present invention relates to an apparatus and method for operating a DVD player, and more particularly, to an apparatus and method for restricting viewing of a DVD player, which blocks inappropriate viewing of video by a teenager.

At present, with the development of broadcasting, communication, and electronic technology, the use of televisions and computers and corresponding portable devices is becoming common to the public. For example, with the development of the video and film industries, various kinds of dramas and movies, which have not been seen in the past, are produced and broadcast through television, and as the television is spread to all homes, family members always watch broadcasting programs. You can watch. Accordingly, television has a problem in that violent and sensational scenes that can be included in dramas or movies differently from existing movie theaters and are conscious of adult's value judgment are exposed to children and adolescents without any filtering.

In addition, the recording function of the DVD recorder is much simpler than using a conventional VCR, so it can be easily used by adults and teenagers. In addition, a recording medium used in a DVD recording device can also record longer than a tape, so that various contents can be recorded on a single disc. Therefore, a problem arises in that a disc on which a content for which minors cannot be viewed, such as violence or pornography, is displayed to the minor without any protection.

1 is a flowchart showing the operation of the conventional parental control method. When a disc is inserted into a DVD player (step 100), the parental level of the inserted disc is checked (step 101). When the parental level of the inserted disc is compared with the parental level set in the DVD player, when the parental level of the inserted disc is greater than the parental level set in the DVD player (step 102), a parental lock code input is requested (step 103). Compare the input Parental Lock code with the Parental Lock code set in the DVD player (step 104). If the input Parental Lock code is different from the Parental Lock code set in the DVD player, stop playing the disc (step 105). If the parental lock code is the same as the parental lock code set in the DVD player, the disc is played (step 106).

Some DVD discs have a parental level that restricts playback of the disc, and are set from level 0 (Child Safe) to level 8 (Adult). Similarly, parental levels can be set for DVD players. If the user wants to restrict viewing at a parental level 5 or higher, set the DVD player's parental level to 4th grade and enter a password. If a disc with a parental level 5 or higher is recognized, the DVD player will be prompted for a password. If the same password is entered, the disc will be played. Otherwise, the tray will be opened without playing the disc.

If you simply restrict the playback of a disc with a higher parental level, the guardian cannot check the youth's viewing habits or the name or watch time of the restricted disc. More protection is needed to protect youth from harmful content.
