Description

  The present invention relates to an in-vehicle electronic device including a display device and a playback device.

  This type of in-vehicle electronic device is mounted on, for example, a one-box car, and various contents can be viewed on the rear seat by a rear seat display device.

  In recent years, such in-vehicle electronic devices are also required to regulate the reproduction of unauthorized content. As a countermeasure, for example, an unauthorized operation that stops audio output when unauthorized content reproduction is detected. It is considered to adopt a content countermeasure technique (for example, Patent Document 1 below).

International Publication No. 2009/050884

  When the illegal content countermeasure technology is used in an in-vehicle electronic device, the volume reproduction restriction (for example, silence) of the illegal content can be surely performed, but in this case, the following problems occur.

  That is, for example, in the backseat of a one-box car, it is often children who watch various contents using the rear seat display device. I can't understand whether it was silent.

  For this reason, children often perform a sound volume changing operation (increasing the sound volume), for example, with a remote controller during the sound reproduction restriction.

  In addition, the children inform the driving driver that the silent state has been reached and ask the driver for countermeasures.

  However, even if the children ask for countermeasures against silence, if the driver is driving, the situation of the backseat cannot be confirmed. (Increase volume) is often executed.

  In such a situation, even if the children or the driver perform a volume change operation (increase the volume), sound output is not controlled because the volume reproduction is restricted (for example, silence is made), and as a result Often, it is determined that the optical disk on which the content is recorded is defective, and the next optical disk is reproduced.

  However, at this time, since a volume changing operation (increasing the volume) is being performed, suddenly high volume audio output is performed, and the children and the driver are surprised and inconvenient.

  Therefore, the present invention aims to improve usability.

  In order to achieve this object, the present invention is provided in at least one of a display device, a control device connected to the display device, a playback device connected to the control device, and the control device and the playback device. An unauthorized content detection unit, and when the unauthorized content is detected by the unauthorized content detection unit, the control device executes an audio reproduction restriction on the display device, and performs a volume change operation during the audio reproduction restriction. Is executed, the display device is configured to display to notify that the volume changing operation is executed during the audio reproduction restriction, thereby achieving the intended purpose.

  As described above, the present invention provides a display device, a control device connected to the display device, a playback device connected to the control device, and an unauthorized content detection unit provided in at least one of the control device and the playback device. And when the unauthorized content detection unit detects unauthorized content, the control device executes audio reproduction restriction on the display device, and a volume change operation is executed during the audio reproduction restriction. In some cases, the display device is configured to display a notification that the volume change operation has been executed during the audio reproduction restriction, which is easy to use.

  That is, in the present invention, when unauthorized content is detected by the unauthorized content detection unit, the audio reproduction restriction is executed in the display device, and when the volume change operation is executed during the audio reproduction restriction, Since the display device is configured to display that the volume change operation has been executed during the audio reproduction restriction, the audio reproduction restriction due to the reproduction of unauthorized content has been executed, and It is displayed that the volume change operation is also executed during execution.

  For this reason, when reproducing the next content, the volume can be corrected, and as a result, there is no sudden output of a large volume, which is convenient.
