[Selection] Figure 1

Description

  The present invention relates to an entertainment system that uses an audio video selector to facilitate device selection.

The karaoke system installed in the karaoke room usually has a large display and a powerful sound device connected to the karaoke commander with multiple connection cables so that multiple customers who come to the store can enjoy karaoke. It has become.
However, if the display or the sound device is used for purposes other than karaoke (video game, movie watching, TV audition), it is necessary to connect a plurality of cables.
Patent Document 1 describes a karaoke system having video signal switching means. Patent Document 2 describes a home theater having an input selector.

Japanese Patent Laid-Open No. 10-282975 Japanese Unexamined Patent Publication No. 2011-41227

  In the karaoke system of Patent Document 1, in addition to the image of the karaoke player, the video of the seat taken by the camera and the playback video or still image of the video player are switched by the video signal switching means (input image switching means), The video of a singer shooting with another camera is inserted.

  However, the karaoke system of Patent Document 1 has poor switching operability because the video signal switching means is controlled by a remote control (because it also serves as a commander operation such as music selection), and the current switching state cannot be seen at a glance. .

  In the home theater of Patent Document 2, a personal computer, a karaoke device, and a game device are incorporated into an AV device, and the device used by the input selector built in the AV device is switched, and the software can be provided with a large screen and powerful sound. Yes.

  However, since all devices are incorporated into an AV device, the AV device is bulky and has poor maintainability. In addition, since the AV device has an input selector, the switching operability is poor (because it is inconspicuous), and the current switching state cannot be seen at a glance.

Recently, there is a news that you want to enjoy the following entertainment in a karaoke room by connecting a personal computer connected to the Internet to the karaoke system.
・ I want to watch online movies with friends on a big screen and powerful sound.
・ I want to enjoy live broadcasting of overseas sports with friends on a large screen and powerful sound.
・ I want to distribute promotional music videos.
・ I want to sing along with the singer on a large screen and powerful sound.
・ I want to sing overseas karaoke music with a large screen and powerful sound.
・ I want to play online games with a large screen and powerful sound.
・ I want to watch videos on video distribution sites with friends on a large screen and powerful sound.

There are also news for customers who want to enjoy the following entertainment in a karaoke room.
・ I want to bring in a BD or DVD and watch it with my friends on a large screen and powerful sound.
・ I want to bring my own mobile device (smartphone, laptop computer, tablet, etc.) and watch the content stored on the mobile device with a large screen and powerful sound.

Moreover, when switching an audio visual apparatus, there exist the following subjects.
If the clerk in the karaoke room changes the connection between multiple audio-visual devices including a karaoke commander and an audio-visual audition device (large screen monitor + powerful audio device) each time, according to customer requests Because it is necessary to go to the karaoke room and work, it takes time and effort. In addition, when the store switching is performed by the customer, the connection changing operation takes time and labor, and there is a possibility that the device may be damaged due to incorrect connection.

  From the viewpoint of failure prevention and power saving, until a visitor selects a stationary PC for a karaoke room, which is one of the audio-visual equipment, the stationary PC is turned off. It is preferable that the stationary personal computer be turned on.

  In other words, the customer can easily operate the audio video selector for switching between a plurality of audio video devices, and the customer can see at a glance which audio video device is currently connected to the audio video listening device. It is necessary.

  The object of the present invention is that the store clerk does not have to go to the karaoke room when switching the four types of audio / video devices in the karaoke room (karaoke commander, stationary PC, optical disc player, and mobile terminal for the customer) With simple operation, you can easily switch between the connection between the four types of audio-visual equipment and the audio / video equipment (amplifier / monitor), and enjoy your favorite entertainment. It is to provide an entertainment system that makes it easy to select a device that can be seen at a glance.
