A technique for setting as a parental level used in playback of a video disc is known (for example, Patent Document 1).
JP 2002-112181 A

  The operation is complicated because it is necessary to input a user ID and a password every time the viewing of the DVD-Video disc is started. In addition, parents should be able to help one by one if an infant who can perform simple operations such as starting playback of a DVD-Video disc but cannot perform other complicated operations wants to watch the DVD-Video disc. .

Also, this technology is applied to an AV system that includes a single DVD-Video playback device and a plurality of monitors used by different users, and outputs the output video of the DVD-Video playback device to an arbitrary monitor. When doing so, the following problems arise.
In other words, the DVD-Video playback device plays a DVD-Video disc at a single parental level setting at a time, so that a plurality of users can simultaneously watch a DVD-Video disc using different monitors. However, when the parental level corresponding to the user of each monitor is different, all users cannot view the DVD-Video corresponding to the parental level corresponding to the user.

  As an AV system including a single DVD-Video playback device and a plurality of monitors used by different users, for example, a front monitor for front seat users and a rear monitor for rear seat users is provided. There is an in-vehicle AV system that outputs an output video of a single DVD-Video playback device to any one of a front monitor and a rear monitor.

  Therefore, the present invention provides a complicated operation in a video system that includes a DVD-Video playback device and a plurality of monitors used by different users, and outputs the output video of the DVD-Video playback device to an arbitrary monitor. It is an object of the present invention to enable video output corresponding to a parental level corresponding to a user who uses the monitor for each monitor without requiring the above.

  In order to achieve the above object, the present invention displays a distributed video and a video output device that outputs video of video content in which viewing restriction level information indicating a viewing restriction level that is a level that restricts viewing is defined. Video distribution means for distributing the video output from the video output device to a monitor designated by a user among the plurality of monitors, and the video distribution means, to a video system including a plurality of monitors, And a viewing restriction level control means for setting a viewing restriction level preset for a distributed monitor in the video output device. Here, the video output apparatus is configured to process the video content for which the viewing restriction level information indicating the viewing restriction level set by the viewing restriction level control unit as a viewing restriction level for restricting viewing is defined. Content video is not output.

  According to such a video system, it is possible to automatically switch the viewing restriction level of video content that can be output by the video output device for each monitor on which the video is output. Therefore, for each monitor, the viewing limit level of video content that can be output to each monitor is determined according to the user using the monitor without requiring complicated operations by the user. Can be automatically limited to different levels.

  Note that such a video system is preset for each of a plurality of monitors to which video is simultaneously distributed by the viewing restriction level control means when the video distribution means distributes video to a plurality of monitors simultaneously. Of these viewing restriction levels, the viewing restriction level with the strongest degree of viewing restriction may be set in the video output device. In this way, when outputting the same video content video to a plurality of monitors, the viewing restriction level of the video content that can be output is set to the highest degree of viewing restriction among the users of the monitor that outputs the video. It is possible to restrict the viewing restriction level suitable for the user to be watched, and to prevent the user from viewing the video content having the viewing restriction level that deviates from the viewing restriction level suitable for the user.

  Alternatively, in such a video system, when the video distribution unit distributes video to a plurality of monitors simultaneously, at least one monitor among the plurality of monitors to which video is simultaneously distributed in the viewing restriction level control unit. All of the preset viewing restriction levels are set in the video output device, and a plurality of viewing restriction levels are set from the viewing restriction level control means in the video output device, and the video content However, when a plurality of video streams in which viewing restriction level information indicating different viewing restriction levels is defined are included, the viewing restriction level is not indicated as a viewing restriction level for restricting viewing. Search for a video stream for which viewing restriction level information is defined, and search for all the video streams searched. Video in the video output device is output to each monitor that simultaneously distributes video to the video distribution means in the viewing restriction level control means. Alternatively, the video of the video stream searched by the video output device for a preset viewing restriction level may be distributed. Here, in this case, the video output device may be a DVD_Video playback device that plays back and outputs video content recorded on a DVD_Video disc, and the viewing restriction level may be a parental level. In this case, the video content including the plurality of video streams in which the viewing restriction level information indicating the different viewing restriction levels is defined is the video content including the parental block, and the viewing indicating the specific viewing restriction level. The video stream in which the restriction level information is defined is formed by one or a plurality of PGCs in which the specific parental level is defined, included in the video content including the parental block.

  By doing so, the video distribution means distributes the video of the same video content to a plurality of monitors at the same time, and the video content is defined as viewing restriction level information indicating a different viewing restriction level. When multiple video streams are included, the video output of the video stream according to the viewing restriction level corresponding to the user of the monitor is output to each monitor to which the video is output without requiring a complicated operation by the user. Can be performed concurrently.

  The video system described above may be a video system mounted on a car. In this case, the plurality of monitors may be a front monitor used by a front seat passenger of the car and a rear seat passenger of the car. And a rear monitor to be used. In the above video system, the video output device may be a DVD_Video playback device that plays back and outputs video content recorded on a DVD_Video disc. In this case, the viewing restriction level is a parental level. . In the above video system, the video output device may be a TV tuner that receives a TV broadcast that broadcasts video content in which the viewing restriction level information is defined, and outputs a video of the received video content. .

  As described above, according to the present invention, a video system includes a DVD-Video playback device and a plurality of monitors used by different users, and outputs an output video of the DVD-Video playback device to an arbitrary monitor. Therefore, it is possible to perform video output corresponding to the parental level corresponding to the user who uses the monitor for each monitor without requiring a complicated operation.
