The user can select and display the video signal that the user wants to see among the video signals input from the camera 10 on each screen of the monitor 41 by using the selection key, and use the character input key to display the desired text ( Message).

The image and screen splitter 208 divides the screen area of the monitor into a plurality so that the image received from the camera is displayed in at least one area of the divided monitor. Through this function, several different video signals can be simultaneously displayed on one monitor. In addition, the image and the screen splitter 208 may form an image of a large screen by dividing one image and then displaying each divided image on one monitor as a mosaic.

The microcomputer 202 uses a counter (not shown), for example, a loss flag bit and a key flag transmitted from the image signal check unit 205 and the key input and the LED unit 207 at intervals of 10 ms. key flag) bits are " 1 " for checking whether the video signal is damaged or whether the selection signal is input by the selection key.

When the user is ready to sing in a room (room 1) in a karaoke room, that is, when coins or a time is input and ready for song selection, the camera 10 installed in the room 1 is operated to The filming of the singer, especially the singer. In this case, one camera is basically installed in each room, but the present invention is not limited thereto, and several cameras may be installed and operated in one room. The video signal photographed as described above is transmitted to the image distribution apparatuses 21, 22, and 23 in operation of each room in the karaoke room including the room 1.

All of the plurality of image signals photographed by the plurality of cameras 10 are transmitted to the image distribution apparatuses 21, 22, 23 in operation of each room in karaoke.

The video signal input unit 201 receives a video signal from the camera 10 and transmits the video signal to the microcomputer 202 and the video signal checker 205. The video signal checker 205 checks whether the video signal received from each camera 10 is lost and transmits the result to the microcomputer 202.

When the song starts for the first time, a video provided uniformly by the karaoke operator is basically displayed on the monitor 41. When the user wants to see the appearance of another room, the user can view the desired room by using the key input and the selection key of the LED unit 207.

The key input and LED unit 207 is provided with the number of the monitors 41a to 41d, and there is a selection key designated for each monitor, and thus, among the video signals received from the camera 10 in each monitor by using this selection key, You can display the image.

A method of displaying the video signal received from the camera 10 on each of the monitors 41a to 41d using the selection key will be described below. When the user presses the selection key corresponding to the monitor 41a once, the corresponding LED is turned on, and the key input and the LED unit 207 transmit the selection signal to the microcomputer 202. Upon receiving the selection signal, the microcomputer 202 searches for an image signal received from the first camera and transmits the image signal to the OSD processing unit 203. The OSD processing unit 203 inserts the room number and other character information into the video signal received from the microcomputer 202, and immediately receives the video signal through the video signal output unit 204 when there is no separate video split or screen split signal. It transfers to the said monitor 41a. If an image split or screen split signal is input, the OSD processor 203 transmits a video signal to the image and screen split unit 208. When the user presses the corresponding selection key once more, the microcomputer 202 searches for the video signal received from the second camera and then sends the video signal to the monitor 41a through the OSD processing unit 203 and the video signal output unit 204. Send it. If there is no video signal received from the camera or the video signal is lost and cannot be displayed on the monitor, a message indicating that connection with the room number that cannot be displayed while displaying the previous screen is impossible (for example, "NO ACCESS"). Is displayed on the monitor 41a. If the corresponding selection key is pressed once and again, the images received from each camera in the third, fourth, etc. are sequentially searched for and displayed on the monitor 41a. Also in the case of the other monitors 41b to 41d, the video signal is possible in the same manner using the designated selection key.

In addition, such a video signal can be displayed (screen split) on at least one region of not only the entire monitor screen but also a multi-segmented monitor screen, and a single video signal is displayed on a plurality of monitors in a mosaic manner. It can be represented as That is, by dividing one monitor screen into multiple screens, several images can be simultaneously displayed on one monitor screen, and by dividing one video into multiple monitors, each divided image is displayed on multiple monitors. You can treat the screen as a single monitor screen.

Hereinafter, an embodiment for the above-described screen division and image division will be described in more detail.

As a method for dividing one monitor into multiples to display (screen split) the video signal from each camera in each divided area, for example, as shown in FIG. The screen is divided into four and four video signals are simultaneously displayed on the monitor 41a. First, the user selects the monitor 41a to be divided using the selection key. Next, the user presses a key input and a screen division key of the LED unit 207. Then, the key input and LED unit 207 transmits the screen split signal to the microcomputer 202. When the screen split signal is received, the microcomputer 202 instructs the image and screen splitter 208 to divide the monitor 41a into four areas, and matches each divided area with a preset monitor selection key. The reason for this division into four areas is that the monitor 41 is made up of four monitors 41a to 41b. That is, the selection key of the monitor 41a is the upper left area of the four-split screen, the selection key of the monitor 41b is the upper right area of the four-split screen, and the selection key of the monitor 41c is the left of the four-split screen. The lower area and the selection keys of the monitor 41d are respectively matched to the lower right area of the divided screen. When the user presses a key input and a selection key of the LED unit 207, the image and screen divider 208 displays the image signal in the corresponding divided area. When the screen division key is pressed again after the screen division is completed, the screen division of the monitor 41a is completed. Screen splitting for the other monitors 41b to 41d is performed in the same manner. This method makes it possible to easily divide a single monitor screen into multiple screens using only a selection key and a screen division key, and to display an image signal independently in each divided area.

The above-described screen splitting method is an embodiment for screen splitting, and various other methods may be used. For example, when the user presses the screen division key in the situation where the user selects the monitor 41a, the image and screen division unit 208 displays a menu for screen division on the monitor 41a. That is, a menu such as how many areas the screen of the monitor is divided, and which video signals are displayed in which areas are displayed. The user may divide the screen of the monitor 41a according to the presented menu and display an image signal in the divided area.

In the case where a single image is to be displayed on a plurality of screens in a mosaic manner, when the user presses the image split key, the image and the screen divider 208 are composed of four monitors as shown in FIG. Split the video into four. Next, each divided image is displayed on the corresponding monitor. That is, among the divided images, the upper left area is displayed on the monitor 41a, the upper right area on the monitor 41b, the lower left area on the monitor 41c, and the lower right area on the monitor 41d, respectively. If there are more screens and the entire monitor 41 is composed of 16, for example, when the screen split key is pressed, the image and screen splitter 208 basically divides the image into 16 images, but the number of images divided by the user. Can be adjusted. In other words, after the user presses the image segmentation key, the user presses a number of consecutive monitor selection keys simultaneously or sequentially, and then presses the image segmentation key again. The image and screen divider 208 divides the image by the number of the selected key. After that, the divided images are displayed on the corresponding monitor.

The above-described image segmentation method is also an embodiment for image segmentation, and by setting a menu for image segmentation, the image signal can be arbitrarily divided into numbers and set to be displayed on arbitrary monitors.

If the user does not want the video signal from the camera 10, pressing the karaoke key, the microcomputer 202 blocks the video signal from the camera 10 and monitors the video signal provided by the karaoke operator through a separate channel ( 41).

In addition, the user may prevent the image signal photographing his room from being transmitted to the outside. If the user of the room 1 where the camera 1 is installed does not want to transmit the video signal photographed to the other room and presses the blocking key, the microcomputer 202 uses the data communication unit 206 for another room (room 2, A signal is transmitted to the microcomputer 202 of the image distribution apparatuses 22 and 23 installed in the room 3 so as not to receive the image signal from the first camera. The microcomputer 202 of room 1 receives only the video signal from the first camera and displays it on the monitor 41. That is, when their video signals are not transmitted to the outside, the video signals of other rooms cannot be seen. When the block key is pressed again, the video signal of room 1 is transmitted back to all other rooms.

By using the present invention, even if the user is in a different room, it is possible to sing or sing a song jointly with each other as if they are in one room. Furthermore, one of the other rooms can be selected so that the conversation only takes place between those two rooms. For example, when the users of room 1 want to talk only with the users of room 2, the users of room 1 write a message using key input and LED unit 207 and specify the room number and send the message. The microcomputer 202 transmits a message to the microcomputer 202 of the designated room (room 2). The microcomputer 202 of the room 2 transmits the received message to the OSD processing unit 203, and the OSD processing unit 203 displays the received message and the room number to which the message is sent to the monitor 41. In response, when users in room 2 press a specific key, the video signals of rooms 1 and 2 are not displayed in other rooms, but only in rooms 1 and 2 so that users of both rooms can have a conversation while watching each other's video. do.

Furthermore, the video distribution apparatuses 21, 22, and 23 further include a recording unit (not shown), so that the image distribution apparatuses 21, 22, and 23 can record their songs. It is possible to record the video data stored in the hard disk to the outside by connecting the network (LAN) connecting the respective video distribution devices (21, 22, 23) in the karaoke to the Internet. Can be.

As shown in FIG. 3, the networks (LANs) in the karaoke rooms to which the present invention is applied are interconnected so that they are not limited to the people in one karaoke room as described above, but can also talk with other karaoke people and sing songs together. Can be. To this end, it is necessary to build a separate operator server 50, the operator server 50 is to enable each of the video distribution device (21, 22, 23) in each karaoke mutual data communication, each video distribution The devices 21, 22, and 23 allow other Internet servers (not shown) to provide Internet services. Selectively presenting the video signal of the other room in each karaoke is the same as the above-described method, but in the case of selectively presenting the video signal from the other karaoke is made through the operator server (50). The operator server 50 receives the video signals from all the cameras in each karaoke, and collects and organizes each karaoke. The video distribution apparatuses 21, 22, and 23 that want to receive video signals from other karaoke rooms may selectively receive the desired video signals after accessing the operator server 50 through the data communication unit 206. In addition, the image distribution device connected to the operator server 50 may exchange messages with other image distribution devices connected to the operator server 50. Of course, in order to receive such an Internet service, each of the image distribution apparatuses 21, 22, and 23 must have an Internet client program installed and executable.

In addition, the operator server 50 may also transmit the video signal received from the cameras of each karaoke to other computers (PC) connected to the operator server 50.

According to the above-described invention, not only sing a song while viewing the screen provided by the karaoke operator in the karaoke, there is an effect that can selectively enjoy watching the appearance of people singing in another room or other karaoke.
