Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is applied to, for example, a video karaoke system in a karaoke box or the like, which is provided in each predetermined space divided by a predetermined partition to reproduce and display a predetermined advertisement video. The present invention relates to an advertisement video playback device.

[0002]

2. Description of the Related Art Conventionally, there has been known a system for providing a video corresponding to a request from a user, such as a video karaoke system in a karaoke box. Since this system is intended to respond to the user's request, the karaoke device stands by in the state of accepting music selection until the user enters the individual room and requests a song, for example as background music. I was only broadcasting cable broadcasting.

[0003]

However, until the user enters the private room of the karaoke box and requests a song, the karaoke device remains in a standby state waiting for song selection, during which the karaoke device itself is effective. It was not used. In particular, when the image display means is provided, the display means has not been effectively used before the main image is displayed in response to the request.

Then, it is conceivable to display the advertisement video of a predetermined length by utilizing the period before the main video is displayed. For example, 15
It is an advertising image with a length of about 2 seconds or 30 seconds. However, even if there are no viewers, the advertisement image is not effective even if the advertisement image is continuously flowed.

In view of these points, the present invention provides a predetermined space in accordance with its original purpose, such as before a user requests a song and a main image is displayed after a user enters a private room of a karaoke box. It is an object of the present invention to provide an advertisement image reproducing device capable of sufficiently exerting an advertising effect by displaying an advertisement image before the operation starts.

[0006]

In order to achieve the above object, the invention according to claim 1 is provided for each predetermined space divided by a predetermined partition, and reproduces and displays a predetermined advertisement image. An advertisement image reproducing device for displaying on the means, the advertisement image storing means for storing the advertisement image, the entrance detecting means for detecting that a predetermined detection target object has entered the predetermined space, and the admission detecting means. An advertisement image reproducing device comprising image reproducing means for sequentially reproducing the advertisement images stored in the advertisement image storing means when the entrance of the detection object into the predetermined space is detected. Is.

[0007] The "predetermined space" may be not only a closed room such as a karaoke box but also a so-called booth configuration in which the space is simply partitioned. A person is a typical "predetermined detection target object". Furthermore, for example, when a so-called drive-in theater is used by utilizing a garage, a movie or the like is viewed while riding in a car, so the car may be the detection target.

On the other hand, the invention according to claim 2 is that said predetermined space is provided for realizing an original purpose by displaying a predetermined image on said display means. The advertisement video reproducing device according to claim 1, wherein the video reproducing means stops the reproduction of the advertisement video when the predetermined video for the original purpose is reproduced on the display means. It is an advertising video playback device.

Here, in terms of "realizing the original purpose by displaying a predetermined image on the display means",
Not only so-called video karaoke but also a so-called video game in which video is displayed on the display means, the drive-in theater, and the like are conceivable.

Further, the invention according to claim 3 is that the predetermined space is provided for use of a request type image providing system for displaying a predetermined main image in response to a request on the display means. 3. The advertisement video reproducing apparatus according to claim 2, wherein the video reproducing means displays the advertisement video when a video according to a request made to the request type video providing system is displayed on the display means. Is an advertisement video reproducing device characterized by stopping the reproduction of.

This request-type video providing system corresponds to the above-mentioned video karaoke system, video game, or the like for displaying a predetermined main video in response to the request on the display means. According to a fourth aspect of the present invention, the predetermined space is provided for use of a request-type video karaoke system for playing a karaoke piece in response to a request and displaying a predetermined background image in accordance with the piece on the display means. 4. The advertisement video reproducing apparatus according to claim 3, which is a so-called karaoke box provided, wherein the video reproducing means displays, on the display means, an image corresponding to a request for a karaoke piece made to the request-type video karaoke system. When displayed, the advertisement image reproducing apparatus is characterized in that the reproduction of the advertisement image is stopped.

According to a fifth aspect of the present invention, there is provided presence detecting means for detecting the presence / absence of the detection target in the predetermined space, and the video reproducing means detects the presence in the predetermined space by the presence detecting means. In a state where it is detected that the target object does not exist, it is possible to reproduce the advertisement image stored in the advertisement image storage unit only when the entry detecting unit detects entry into the predetermined space. The advertising image reproducing device according to any one of claims 1 to 4.

As the "presence detecting means", a non-contact type sensor such as an infrared sensor, or, for example, in a karaoke box or the like, a sensor is provided on a stage or a chair so that a person is standing on the stage or on the chair. You may decide that you are sitting.

[0014]

According to the advertising image reproducing apparatus of the first aspect of the present invention configured as described above, the entrance detecting means allows the predetermined object to be detected to enter the predetermined space partitioned by the predetermined partition. When the entrance detecting means detects the entrance of the object to be detected into the predetermined space, the video reproducing means sequentially reproduces the advertisement images stored in the advertisement image storing means, and reproduces the advertisement images. The image is displayed on the display means.

Therefore, for example, when applied to a karaoke box, when a user enters the room, an advertisement is automatically displayed, and the karaoke user is requested to use the period until the song is requested. Advertisements can be made. In this case, in particular, since it is aimed at karaoke users, the content of the advertisement can be specified, so that the advertisement provider can also provide targeted advertisement.

Further, the "predetermined space" is not limited to a karaoke box, but may be a booth or the like which is simply partitioned by a stand or the like, or a garage in a drive-in theater, as described above. Further, the entrance detection means detects that a predetermined detection target object has entered the predetermined space.
In the case of the karaoke box, an entrance sensor is provided on the door to detect the entrance of a person, or in the case of a drive-in theater using the garage, it is detected that a car has passed a predetermined entrance. You may do it.

The display means may be provided exclusively for displaying the advertisement image, but as shown in claim 2, by displaying a predetermined image, the original purpose is realized. When the display means is used to display an advertisement and the video reproduction means reproduces a predetermined video for the original purpose on the display means, the reproduction of the advertisement video may be stopped. Conceivable.

For example, in the case of so-called video karaoke, since the display means for displaying the video is originally provided,
You should use it. However, since the original purpose is to display the background image corresponding to the karaoke piece, it is preferable to display the advertisement only during the period after the room is displayed until the background image is displayed.

Further, in addition to video karaoke, in a so-called video game played by displaying an image on the display means, a drive-in theater on a screen, etc.,
Since it has a mechanism for displaying an image for its original purpose, it can be used.

The third aspect of the present invention is a case where the present invention is applied to a request type image providing system for displaying a predetermined main image corresponding to a request on the display means. A typical example thereof is a request-type video karaoke system for playing a karaoke piece in response to a request and displaying a predetermined background image in accordance with the piece on a display means. In this case, the video reproduction means stops the reproduction of the advertisement video when the video corresponding to the request for the karaoke piece made to the request type video karaoke system is displayed on the display means.

Although it has been described that the entrance of the object to be detected into the predetermined space is detected and the reproduction of the advertisement video is started, there is a case where it is inconvenient to always reproduce the advertisement video when the entrance is detected. . For example, to explain with the example of a karaoke box, it is certainly good to start playing the advertisement video when first entering a room where nobody is present, but it is used by multiple people, and one of them is once outside the room. There is a problem if the advertisement video is played back even when the player exits and enters the room again. In other words, karaoke itself is still used,
Even if the entrance is detected while the background image corresponding to the song is being reproduced, it is not preferable that the advertisement image is reproduced from the original purpose.

Therefore, as described in claim 5, the presence detecting means detects the presence or absence of the detection target object in the predetermined space, and the video reproducing means detects the presence of the detection target object in the predetermined space by the presence detection means. If it is detected that the advertisement image stored in the advertisement image storage unit is reproduced only when the entrance detection unit detects the entry into the predetermined space in the state that it is not detected, Advertising video playback can be realized.

That is, in a karaoke box or the like, if there is a person inside, it is judged that it is not the timing to start the advertisement image even if a person comes in from outside. for that reason,
The advertisement video will be played only for an appropriate period when the user first enters the room.

41, ROM 43, RAM 45, hard disk 47,
Audio reproduction circuit 49, video reproduction circuit 51, serial I / F
53 and a bus 55 are provided.

The hard disk 47 corresponds to the advertisement image storage means in the present invention, and encodes a plurality of advertisement data and stores it as advertisement sound data and advertisement image data. The voice reproduction circuit 49 converts the encoded advertisement voice data into an advertisement voice signal, and this advertisement voice signal is output to the voice changeover switch 15 on the karaoke control unit 10 side.

The video reproduction circuit 51 is for converting the encoded advertisement video data into an advertisement video signal, and this advertisement video signal is output to the video changeover switch 23 on the karaoke control unit 10 side. . The serial I
/ F53 receives the request to start the reproduction of the advertisement video from the karaoke control unit 10, and the karaoke control unit 10
This is an interface for notifying the playback end.

The ROM 43 stores a control program for controlling the entire advertisement reproducing unit 40, and the RAM 45 is a work area for executing the control program. Next, of the operations of the present system configured as described above, the processing relating to the reproduction control of the advertisement video will be described with reference to the flowcharts of FIGS.

First, the processing on the karaoke control unit 10 side will be described with reference to FIG. In this karaoke control unit 10, when the power is turned on, C
The PU 1 initializes each control circuit by the control program stored in the ROM 3 (step 100. The step will be simply referred to as S hereinafter), and waits for a song request from the keyboard 31 (S110). If there is a request (S110: YES), the CPU 1 causes the voice changeover switch 1
5 and the video selector switch 23 are switched to the music audio signal side and the background video signal side, respectively (S120), and a process related to karaoke performance is performed (S130).

The karaoke performance process will be described in detail. The CPU 1 reads out music data and background image data corresponding to the requested music from the hard disk 7,
The performance data in the music data is transferred to the audio reproduction circuit 13, and the lyrics data and the background video data in the music data are transferred to the video reproduction circuit 21, respectively. The voice reproduction circuit 13 converts the received performance data into a music voice signal and outputs it to the voice changeover switch 15. The video reproduction circuit 21 also converts the received lyrics data and background video data into a music video signal and outputs the music video signal to the video switch 23.

The music voice signal is sent to the mixer amplifier 17, amplified and electrically amplified, and is mixed with the user's singing voice input through the microphone 20 at an appropriate ratio. The mixed voice signal is a speaker. It is output to the outside as a performance sound by 19. On the other hand, the music video signal (consisting of the background video signal and the lyrics video signal) is sent to the monitor television 25 and displayed in a state in which the lyrics telop is combined with the background video.

When the karaoke performance process for the requested song is completed in this way, the process returns to the state of waiting for the request for the song (S110). On the other hand, if there is no request input (S110: NO), it is determined whether or not there is a room entry based on the detection signals from the room entry sensor 34 and the room presence sensor 35 (S140). If there is no entry (S
140: NO), and returns to S110 to determine whether or not there is a request input. On the other hand, if there is entry (S14
0: YES), the CPU 1 switches the voice changeover switch 15 and the video changeover switch 23 to the advertisement voice signal side and the advertisement video signal side, respectively (S150).

Here, a supplementary explanation will be given regarding the "determination as to whether or not there is room entry" in S140. This entry is
First, it is determined whether or not there is an entry into the room. Even if a person comes in from the outside and the entry sensor 34 detects the entry into the room, if another person is already present in the room, it means here. It does not correspond to "entry". That is, even if the entry sensor 34 detects entry, the presence sensor 3
When it is detected by 5 that there is another person in the room, a positive determination is not made in S140. The entry sensor 34 detects the entry of the room, and the presence sensor 35
In some cases, an affirmative determination is made in S140 only when it is detected that the user is not in the room.

Returning to FIG. 3, after the voice changeover switch 15 and the video changeover switch 23 are switched to the advertisement voice signal side and the advertisement video signal side in S150, the serial I / F 2
The advertisement reproduction unit 40 is requested to reproduce the advertisement image via the S9 (S160). Next, CPU1 is a serial I / F
The advertisement reproduction unit 40 waits for an advertisement reproduction end notification via 29 (S170).

When the advertisement reproduction end notification is received (S1
70: YES), and it is determined whether or not there is a request input for a song (S180). And if there is a request input,
The process moves to S120 and karaoke performance processing is performed. On the other hand, if there is no song request input, the process returns to S160 to request the advertisement reproduction unit 40 to reproduce the advertisement video.

Next, the operation of the advertisement reproducing unit 40 will be described with reference to the flowchart of FIG. When the power is turned on, the advertisement reproducing unit 40 has a CPU 41.
Initializes each control circuit by the control program stored in the ROM 43 (S200), and waits for a reproduction request from the karaoke control unit 10 via the serial I / F 53 (S210). If there is a reproduction request from the karaoke control unit 10 (S210: YES), processing related to advertisement reproduction is performed (S220).

Explaining the advertisement reproduction processing in S220, the CPU 41 selects the advertisement data stored in the hard disk 47, transfers the advertisement voice data in the advertisement data to the voice reproduction circuit 49, and the advertisement video data It is transferred to the video reproduction circuit 51. The voice reproduction circuit 49 converts the received advertisement voice data into an advertisement voice signal and outputs it to the voice changeover switch 15 of the karaoke control unit 10. Further, the video reproduction circuit 51 converts the received advertisement video data into an advertisement video signal, and the karaoke control unit 10
To the video selector switch 23.

As described above with reference to S150 in FIG. 3, in this case, since the voice changeover switch 15 and the image changeover switch 23 of the karaoke control unit 10 are switched to the advertisement voice signal side and the advertisement video signal side, respectively, The advertisement sound signal output to the changeover switch 15 is output to the outside as sound via the mixer amplifier 17 and the speaker 19. On the other hand, the advertisement video signal output to the video switch 23 is sent to the monitor television 25 and displayed.

When the transfer of one piece of advertisement data is completed in this way, the CPU 41 outputs an advertisement reproduction end notification to the karaoke control unit 10 via the serial I / F 53 (S230) and waits for the next advertisement reproduction request. (S21
0). A negative determination is made in S180 of FIG. 3, that is, if there is no request input even after the reproduction of one advertisement is completed, a reproduction request is made again in S160. In that case, an affirmative judgment is made in S210 of FIG. The advertisement is reproduced (S220).

The plurality of advertisement data stored in the hard disk 47 are sequentially reproduced every time an advertisement reproduction request is received from the karaoke control unit 10 in a predetermined order (including a case of randomly selecting). For example, numbers 1 to n are set for a plurality of pieces of advertisement data (probably n pieces), and the advertisement images are reproduced in order by incrementing the number of the advertisement image to be reproduced. Further, when the reproduction of the last (nth) advertisement data is completed, the number of the advertisement data to be reproduced is initialized so that the reproduction of the first (1st) advertisement data is sequentially repeated. In this way, the karaoke control unit 10
While the reproduction request comes from, the 1st to nth advertisement videos are sequentially repeated and reproduced.

As described above, according to the video karaoke system of this embodiment, the advertisement is automatically reproduced when the user enters the room, and the period until the song is requested is used. It is possible to advertise to karaoke users. In this case, in particular, since it is aimed at karaoke users, the content of the advertisement can be specified, so that the advertisement provider can also provide targeted advertisement.

Further, since the advertisement is reproduced only when there is an entry into the room for the first time, even if the entry sensor 34 detects the entry into the room, the presence sensor 35 indicates that the person is in the room. If the entry is detected, the entry is not judged to be “entry”, and the entry sensor 34 detects entry, and the entry sensor 35 only detects that the entry is “not entered”. It is determined that it is time to reproduce the advertisement. In this way, it does not make sense to play the advertisement while there are no people, and it does not play even if it disturbs the original purpose (here, karaoke), so there is no need to enter the room first. In this case, the advertisement can be played by the time the song is requested.

In the above embodiment, after the reproduction request for the advertisement data is issued in S160, the process proceeds to S180 after the end notification is received from the advertisement reproduction unit 40. Therefore, if there is a request during the reproduction of the advertisement. Does not start the performance processing of the requested karaoke piece until the reproduction of the advertisement data being reproduced at that time ends. On the other hand, if interrupt processing is adopted and the karaoke control unit 10 makes a request, the reproduction of the advertisement data is in progress in order to immediately perform the performance processing of the karaoke piece and the background image processing. However, it may be stopped immediately.

In this embodiment, the CPU 1 of the karaoke control unit 10 and the CPU of the advertisement reproducing unit 40
41 corresponds to the video reproducing means of the present invention, and FIG. 3 of the processing executed by the CPU 1 and FIG. 4 of the processing executed by the CPU 41 (specifically, the processing of S110 and S140 to S180) are the video reproducing means. Corresponds to the processing of.

The present invention is not limited to the embodiments as described above, and may be carried out in various modes without departing from the gist of the present invention. For example, in the above embodiment, the combination of the advertisement sound and the advertisement video is taken as the reproduction of the advertisement, but the advertisement sound is not always necessary and only the advertisement video may be reproduced.

In the above embodiment, the case where the present invention is applied to the video karaoke system has been described, but the present invention can be applied to a so-called video game in which an image is displayed on a CRT, a drive-in theater which displays an image on the screen, and the like. . For example, in some video games, the game console itself is provided in a predetermined space partitioned by one booth, so in that case, when a person enters the booth, an advertisement is reproduced. You can do it like this. Even if there is no partition for a single game machine, the advertisement may be played when there is entry into the game room where a plurality of game machines are arranged.

In the above embodiment, the detection target of the entry sensor 34 and the occupancy sensor 35 is a person. However, in the case of a drive-in theater using a garage, for example, watching a movie while riding in a car. Therefore, it may be possible to detect that the vehicle has passed through a predetermined entrance by using the vehicle as a detection target.
