Description

The present invention relates to an optical disc apparatus that reproduces information recorded on an optical disc, or records information on an optical disc or reproduces information recorded on an optical disc, and in particular, has a function of muting a voice that a user does not want to output. The present invention relates to an optical disc apparatus having the same.

In recent years, DVDs (digital versatile discs), which are optical discs capable of recording information such as a large amount of video and audio data such as movies, are becoming widespread. As a DVD type, a DVD-RO in which information is recorded on the manufacturer side and cannot be rewritten on the user side
An M type DVD, a DVD-R type DVD in which information can be recorded only once on the user side, a DVD-RW (DVD-RAM) type DVD rewritable on the user side, and the like are known. Information recorded on these DVDs can be reproduced by a DVD player or a DVD recorder, and a DVD-R type DVD or a DVD-RW (DVD-RAM) type DV.
Information can be recorded on D or the like with a DVD recorder.

By the way, a movie or the like recorded on a DVD-ROM type DVD may include a violent scene, an obscene scene, or the like for children's education. Therefore, for such educational scenes, there are some restrictions on viewing restrictions on playback. Such a regulation is called parental, and a parental level that restricts viewing according to the content is set in advance on the DVD.

On the other hand, an optical disk device such as a DVD player or a DVD recorder that reproduces information on an optical disk such as a DVD has a parental function that restricts reproduction of information on the optical disk, and the parental level of the device set by the user is stored in the memory. It is remembered. The parental level of the apparatus can be arbitrarily set by the user by operating the remote controller of the optical disk apparatus or the like. In addition, when changing the parental level of the device, for example, the user enters a password consisting of several digits in advance as a password into the device, releases the parental lock, and changes the parental level. ing.

The above-mentioned viewing restrictions based on the parental level are only for limiting the viewing of video and audio for a certain scene, and in some scenes where viewing is not restricted, only audio may be uncomfortable for the user. There may be. In addition, when a television program is recorded and then played back, there may be a case where a certain sound feels uncomfortable for the user. However, in the conventional optical disc apparatus, such an uncomfortable sound is simply flowing down, and an unpleasant sound is also output, giving the user an unpleasant feeling.

Therefore, in the prior art of Patent Document 1, when harmful words are included in the voice information, the voice is muted, so that an unpleasant voice is not output and the user is not affected. It wo n’t be uncomfortable, but when the sound is suddenly muted, it ’s gone, so the user does n’t know what happened to the device,
It is misunderstood that the sound output system or the like is out of order, and a problem arises that the user becomes unusable.

In the related art of Patent Document 2, video display and audio output are stopped in the set reproduction prohibition range, and only subtitles are displayed. In the case of interlaced playback, a message indicating that is displayed. If there is an uncomfortable sound outside the set reproduction prohibition range, the unpleasant sound is output, giving the user unpleasant feeling. In addition, since the voice is lost when the voice suddenly stops, the user does not know what happened to the device, and it is misunderstood that the voice output system is malfunctioning. For the user, there arises a problem that usability deteriorates.

In the prior art of Patent Document 3, if the playback scene is a restricted scene, a peep sound is output instead of the content sound, or the sound is muted. If this happens, an unpleasant sound is output, giving the user an unpleasant feeling. In addition, this conventional technology also suddenly mutes the sound,
Since there is no sound, the user does not know what happened to the device, and it is misunderstood that the sound output system or the like is out of order.
