2. Description of the Related Art Conventionally, in a video / audio reproducing apparatus which reads data from a digital video disk in which video and audio are recorded and reproduces the video and audio, a certain predetermined video or audio can be reproduced without permission. Some have special processing that does not play. This special processing is called parental processing, and in violent scenes or scenes of violent language use, for example, to prevent children from watching those scenes, processing that does not display the video or cuts audio is performed. It is a thing.

This type of conventional parental processing has been performed as follows. First, on a disc on which video data and audio data are recorded, it is indicated that the video data and audio data of a violent scene or a scene of violent language is a parental area in advance when the disc is manufactured. Rental data is added and recorded. Then, in the video / audio reproducing apparatus, if the video data and the audio data to be read from the disc and reproduced are those with parental data added, it is necessary to perform a process of not reproducing the data without the reproduction permission. Was to do.

On the other hand, in an information recording apparatus for recording information on a write-once type recording medium, in order to prevent reproduction of a portion erroneously recorded on the recording medium, data for prohibiting the reproduction is provided. An apparatus for recording on a recording medium is known (see, for example, Japanese Patent Laid-Open No. 7-93951). Further, in a disc reproducing apparatus for reproducing a recording medium to which a parental level area is added in advance according to the information content, only the information of an arbitrary parental level is skipped and reproduced, whereby the parental area and the parental level are reproduced. There is known a device capable of confirming the contents of the above (see, for example, JP-A No. 11-144441). In addition, in a reproducing device that reproduces music data recorded on a recording medium, the address of the stop position when the reproduction was last stopped is stored, and when the reproduction is restarted, the address of the stored stop position is used. There is known a device having a resume function that restarts the reproduction even if the reproduction is stopped in the middle of a song by starting the reproduction (for example, Japanese Patent Laid-Open No. 2000-
(See Japanese Patent No. 331466).

[0005]

However, in the above-described conventional video / audio reproducing apparatus, parental management depends on whether parental data is set on the disk, and parental data is set. It was only possible to perform parental processing on existing discs. Therefore, in the case of a disc with no parental data set, even if there are scenes that are harmful to children, such as violent scenes or scenes of violent language use, those scenes will be played back. However, there is a problem that the viewers watch the harmful scenes.

[0006] Further, the above-mentioned JP-A-7-93951, JP-A-11-144441, and JP-A-200
