Description

REPRODUCTION DEVICE, REPRODUCTION SYSTEM, REPRODUCTION METHOD, INFORMATION RECORDING MEDIUM, AND PROGRAM

The present invention relates to a playback device, a playback system, a playback method, an information recording medium, and a program suitable for easily outputting sound with enhanced acoustic effect.

Playback devices that play various multimedia contents such as video, audio, text, etc. and provide them to users are widespread. For example, the game device outputs video and audio for demonstration (hereinafter referred to as “demo”) when the user is not playing a game, and when the user starts the game, the demo ends and outputs video and audio of the main game. To do. For example, a DVD (Digital Versatile Disk) playback device outputs a title screen and title audio when a DVD-ROM (Digital Versatile Disk Disk-Read Only Memory) is inserted, and when the user instructs the start of the main movie playback, Output audio.

When multiple playback devices that output video and audio are installed nearby, for example, in a game center, various sounds may be heard nearby, making it difficult to hear. There is also a playback device. For example, Patent Document 1 discloses a game system that changes the volume of sound according to the distance between game devices so that sounds flowing from other game devices in the vicinity do not get in the way.

Japanese Patent No. 4079401

By the way, in recent years, acoustic technology has been developed such as the spread of a multi-channel surround system using a plurality of speakers, and the user's attention to sound is also increasing. However, in order to increase the acoustic effect by introducing an advanced surround system, new peripheral devices such as speakers and amplifiers must be purchased and installed, and the user has a lot of financial and time costs. I will be forced. In addition, there are some playback devices that are currently available, and it may be difficult to install new peripheral devices in terms of hardware, or there may not be enough space like the above-mentioned game center housing, It was sometimes difficult to obtain a high acoustic effect easily.

The present invention solves such problems, and provides a playback device, playback system, playback method, information recording medium, and program suitable for easily outputting sound with enhanced acoustic effects. Objective.

In order to achieve the above object, the following invention is disclosed in accordance with the principle of the present invention.

A playback device according to a first aspect of the present invention is a playback device that is arranged adjacent to another playback device and plays back multimedia information in response to a request from a user, and includes a display unit and an audio output unit Is provided.
The display unit displays a demo image that prompts the user for a request or a response image that responds to a request from the user.
The sound output unit outputs sound.
And the audio output unit
(A) When the image displayed on the display unit is a response image, the sound corresponding to the response image is output,
(B) When the image displayed on the display unit is a demo image and another playback device arranged adjacently displays a response image, audio corresponding to the response image displayed by the other playback device is displayed. Output,
(C) When the image displayed on the display unit is a demo image and another playback device arranged next to the display displays the demo image, audio corresponding to the demo image displayed by the playback device is output. .

The playback device of the present invention provides users with multimedia information using images and sounds, such as movies, music, games, and advertisements. The images displayed by the playback device include a demo image and a response image.
The demo image is an image that prompts the user to make a request. The request referred to here is a request to start providing multimedia information. For example, the user can input a request to the playback device by pressing a predetermined playback button or inserting a coin. When the user inputs a request, the playback apparatus switches the display from the demo image to the response image. The response image is an image that is displayed after a request is input from the user.

For example, in the case of a movie, the title image that waits for the reproduction of the main part of the movie corresponds to the demo image, and the image of the main part after inputting the reproduction instruction corresponds to the response image.
For example, in the case of a home game, an image before pressing a game start button (typically immediately after power-on) corresponds to a demo image, and an image of a game portion after pressing the game start button corresponds to a response image.
For example, in the case of an arcade game, an image waiting for coin insertion corresponds to a demo image, and an image of a game portion after coin insertion corresponds to a response image.

The playback devices are connected so that they can communicate with each other and are arranged adjacent to each other. For example, two playback devices may be arranged side by side, or three or more playback devices may be arranged in series or in parallel. In the present invention, the adjacent state is a state close to a level where sounds output from sound output devices (speakers) included in the playback device can be heard from each other. At least one speaker is connected to the playback device.

The sound output from the speaker of the playback device includes a demo sound associated with the demo image and a response sound associated with the response image. The playback device basically plays back the response image and the response sound as a pair, and plays the demo image and the demo sound as a pair. However, the playback device of the present invention can change the playback pair in accordance with the playback state of another playback device adjacent to the playback device.

That is, when the playback device displays a demo image and the adjacent playback device displays a response image, the playback device plays back the response sound associated with the response image displayed by the adjacent playback device instead of the demo sound. To do. At this time, the adjacent playback device plays back the response image and the response sound together. Therefore, the user can listen to the game sound not only from the speaker of the playback device operated by the user but also from the speaker of the playback device adjacent to the user.

For example, in a situation where two home game machines are arranged and each player is playing a game, if one player is continuing the game and the other player interrupts or cancels the game, the player who continues the game Can listen to the game sound output from the speaker of the next free game console as well as the speaker of their own game console. Therefore, the player can listen to the sound with improved acoustic effect.

For example, when a game image is displayed when a coin is inserted into one of the two adjacent housings while a demo image and a demo sound are being played back, Not only the game sound (response sound) is output from the speaker, but also the game sound (response sound) is output from the speaker of the other casing that is still reproducing the demo image.
Therefore, the game player can play the game while listening to the sound output not only from his own case but also from the case of the next empty seat. Even if only one speaker is connected to one housing, the player can listen to the sound with improved acoustic effect output from two (or more) speakers.

According to the present invention, the playback device can easily output sound with enhanced acoustic effect without changing the hardware configuration, such as adding speakers or upgrading peripheral devices.

A playback device according to another aspect of the present invention is a playback device that is arranged to be adjacent to the other two playback devices on the left and right, and plays back multimedia information in response to a request from a user. An audio output unit is provided.
The display unit displays a demo image that prompts the user for a request or a response image that responds to a request from the user.
The sound output unit outputs sound.
The audio output unit is disposed on the left and right of the display unit.
Then, the audio output unit arranged on the left is displayed by the other reproduction device arranged on the left side depending on whether or not the other reproduction device arranged on the left side of the reproduction device displays the response image. One of the audio corresponding to the response image and the audio corresponding to the demo image displayed by the playback device is output.
Furthermore, the audio output unit arranged on the right is displayed by another reproduction device arranged on the right side depending on whether or not another reproduction device arranged on the right side of the reproduction device displays a response image. One of the audio corresponding to the response image and the audio corresponding to the demo image displayed by the playback device is output.

Similarly to the above, the playback apparatus of the present invention plays back a combination of a demo image or response image and a demo sound or response sound. The playback devices are connected so as to communicate with each other, and are arranged adjacent to each other on the left and right. Typically, two or more playback devices are arranged next to each other in series. At least two speakers are connected to the playback device.
For example, one speaker is arranged on the left side facing the monitor, and the other speaker is arranged on the right side facing the monitor. At the listening point, the left sound (L sound) and the right sound (R sound) can be heard.

The playback device can change the combination to be played back.
In other words, the playback device that is displaying the demo image is either the demo sound that is associated with the demo image that is being displayed, or the left The response sound of the playback device is played back.
More specifically, when the playback device on the left side displays the response image, the playback device that is displaying the demo image plays back the response sound associated with the response image displayed by the playback device on the left side.
Therefore, the user can hear the sound not only from the speaker of his / her playback device but also from the speaker of the adjacent playback device. At this time, the R sound is emphasized for the user who uses the playback device on the left side of the playback device that is displaying the demo image.

Similarly, the playback device that is displaying the demo image is a demo sound that is associated with the demo image that is being displayed, depending on whether the playback device on the right displays the demo image or the response image, The response sound of the adjacent playback device is played back.
More specifically, when the playback device that is displaying the demo image displays the response image, the playback device that is displaying the response image that is associated with the response image displayed by the playback device that is adjacent to the right.
Therefore, the user can hear the sound not only from the speaker of his / her playback device but also from the speaker of the adjacent playback device. At this time, the L sound is emphasized for the user who uses the playback device on the right side of the playback device displaying the demo image.

For example, in a situation where three home game machines are arranged and each player plays a game, if the central player continues the game and the remaining players interrupt or stop the game, the player who continues the game You can listen to the game sound that is output not only from the speakers of your game console, but also from the speakers of the free game consoles on both sides.
Therefore, the player can listen to the sound with improved acoustic effect.

For example, when all three adjacent cases are playing a demo image and a demo sound, if a coin is inserted into the central case and a game image is displayed, the case of the case where the coin has been inserted is displayed. Not only the game sound is output from the speaker, but also the game sound is output from the speakers of the adjacent housings that are still playing the demo image.
Therefore, the game player can play the game while listening to the sound output not only from his own case but also from the case of the next empty seat. Even if only two speakers are connected per case, if any of the adjacent playback devices is playing a demo, the player will output from more than three speakers, improving the acoustic effect. Listen to the sound.

A playback device according to another aspect of the present invention is a playback device that is disposed opposite to another playback device and plays back multimedia information in response to a request from a user, and includes a display unit and an audio output unit. .
The display unit displays a demo image that prompts the user for a request or a response image that responds to a request from the user.
The sound output unit outputs sound.
And the audio output unit
(X) When the image displayed on the display unit is a response image, the sound corresponding to the response image is output,
(Y) When the image displayed on the display unit is a demo image and the other playback device arranged oppositely displays the response image, the sound corresponding to the response image displayed by the other playback device Output
(Z) When the image displayed on the display unit is a demo image, and another playback device arranged oppositely displays the demo image, audio corresponding to the demo image displayed by the playback device is output. To do.

The playback device of the present invention also plays back a combination of a demo image or response image and a demo sound or response sound, as described above. The playback devices are connected so as to be able to communicate with each other, and are arranged adjacent to each other in the front and rear. Typically, the two playback devices are arranged so as to face each other and be adjacent to each other. At least one speaker is connected to the playback device.

The playback device can change the combination to be played back.
That is, when the playback device displays a demo image and the adjacent playback device displays a response image, the playback device plays back the response sound associated with the response image displayed by the adjacent playback device instead of the demo sound. To do. At this time, the adjacent playback device plays back the response image and the response sound together.
Therefore, the user can hear the sound not only from the speaker of the playback device that he / she is operating, but also from the speaker of the playback device behind him / her.

For example, in a situation where two home-use game machines are lined up and each player plays a game with his back turned, if one player continues the game and the other player interrupts or cancels the game, continue the game. The player who is playing the game can output the game sound not only from the speaker of his game machine but also from the speaker of the empty game machine behind.
Therefore, the player can listen to the sound with improved acoustic effect.

For example, when two adjacent housings facing each other are playing a demo image and a demo sound, when a coin is inserted into one housing and a game image is displayed, the coin is inserted. Not only the game sound is output from the speaker of the housing, but also the game sound is output from the speaker of the other housing that is still reproducing the demo image.
Therefore, the game player can play the game while listening to the sound output not only from the speaker in his own casing but also from the speaker in the empty seat casing behind him. Even if only one speaker is connected to one housing, if the adjacent playback device is performing demo playback, the player listens to the sound with improved acoustic effect output from two or more speakers. be able to.

A playback system according to another aspect of the present invention is a playback system having a first playback device and a second playback device, and the first playback device and the second playback device are arranged adjacent to each other.
First, the first playback device includes a first display unit and a first audio output unit.
The first display unit displays a first demo image that prompts the user for a request or a first response image that responds to a request from the user.
The first sound output unit outputs sound.
Next, the second playback device includes a second display unit and a second audio output unit.
The second display unit displays a second demo image that prompts the user for a request or a second response image that responds to the request from the user.
The second sound output unit outputs sound.
And
(P) When the first display unit displays the first response image, the first sound output unit outputs a sound associated with the first response image in advance,
(Q) When the first display unit displays the first demo image and the second display unit displays the second response image, the first audio output unit and the second audio output unit respectively Output audio that is pre-associated with the image
(R) When the first display unit displays the first demo image and the second display unit displays the second demo image, the first sound output unit outputs the sound previously associated with the first demo image. The second sound output unit outputs sound that is associated with the second demo image in advance.

Each of the playback devices constituting the playback system of the present invention also plays back a combination of a demo image or response image and a demo sound or response sound, as described above. The playback system is composed of at least two playback devices. The playback devices are connected so as to be communicable with each other and are arranged adjacent to each other. At least one speaker is connected to the playback device.

Each playback device can change the combination to be played back.
That is, when one playback device (first playback device) displays a demo image and the other playback device (second playback device) displays a response image, one playback device uses the other instead of the demo sound. The response sound associated with the response image displayed by the playback device is played back. At this time, the adjacent playback device plays back the response image and the response sound together.
Therefore, the user can hear the sound not only from the speaker of his / her playback device but also from the speaker of the adjacent playback device. When there are two adjacent playback devices, either one may be used as the first playback device. If either one is determined as the first playback device, the other is determined as the second playback device.

For example, in a situation where two home game machines are arranged and each player plays a game, if one player is continuing the game and the other player interrupts or cancels the game, The game sound is output not only from the speaker of your game machine but also from the speaker of the next empty game machine.
Therefore, the player can listen to the sound with improved acoustic effect.

For example, when a game image is displayed when a coin is inserted into one of the two adjacent housings while a demo image and a demo sound are being played back, Not only the game sound is output from the speaker, but also the game sound is output from the speaker of the other casing that is still reproducing the demo image.
Therefore, the game player can play the game while listening to the sound output not only from his own case but also from the case of the next empty seat. Even if only one speaker is connected to one housing, if the adjacent playback device is performing demo playback, the player listens to the sound with improved acoustic effect output from two or more speakers. be able to.

According to the present invention, the playback system can easily output audio with enhanced acoustic effects without changing the hardware configuration, such as adding speakers or upgrading peripheral devices.

The second playback device may further include a notification unit that notifies the first playback device of a playback state indicating whether the second display unit displays the second demo image or the second response image.
Then, the first audio output unit may determine whether the second display unit displays the second demo image or the second response image based on the notified reproduction state.

That is, the playback devices constituting the playback system can notify each other of the playback state and output sound with enhanced acoustic effect according to the situation. The reproduction state is information indicating whether a demo image or a response image is being reproduced.

Note that the playback device may notify the playback device to the adjacent playback device when a change occurs in its playback state, or may notify each other at regular intervals. Further, when the display is changed from the demo image to the response image, the playback state may be inquired to the adjacent playback device, and the adjacent playback device may return its playback state in response to the inquiry.

The voice associated with the second response image may include a first type voice and a second type voice.
And (q1) When the first display unit displays the first demo image and the second display unit displays the second response image, the first audio output unit is associated with the second response image in advance. The first type of sound may be output, and the second sound output unit may output the second type of sound associated with the second response image in advance.

Here, there are various variations in the classification methods of the first type and the second type.
For example, audio data can be created separately for each musical instrument, and can be classified into audio corresponding to the first type musical instrument and audio corresponding to the second type musical instrument.
For example, the main melody voice data and the sub melody voice data are created separately, and can be classified into a first type voice belonging to the sub melody and a second type voice belonging to the main melody.
For example, L sound data and R sound data can be created separately and classified into a first type sound belonging to the L sound and a second type sound belonging to the R sound.
In addition to the above, the voice can be classified into the first type and the second type by an arbitrary classification method. For example, it may be created by dividing it into a plurality of audio data and classified randomly.

When one playback device (first playback device) displays a demo image and the other playback device (second playback device) displays a response image, one playback device uses the other instead of the demo sound. Among the response sounds associated with the response image displayed by the playback device, the first type of sound is reproduced. In addition, the other playback device plays back the second type of sound among the response sounds associated with the response image to be played back by itself.
Therefore, the user can hear the sound not only from the speaker of his / her playback device but also from the speaker of the adjacent playback device, and the acoustic effect is increased.

The first playback device may be arranged on the left side of the second playback device.
The audio associated with the second response image includes left audio that should be output from the left side of the user of the second playback device and right audio that should be output from the right side of the user of the second playback device. It may be.
(Q2) When the first display unit displays the first demo image and the second display unit displays the second response image, the first audio output unit outputs the left audio and the second audio output The unit may output right audio and / or left audio.

That is, the first playback device and the second playback device are arranged in this order from the left. The response voice includes an L sound created on the assumption that it is output from the left side of the listening point and an R sound created on the assumption that it is output from the right side of the listening point.
When the first playback device displays a demo image and the second playback device displays a response image, the first playback device is associated with the response image displayed by the second playback device instead of the demo sound. The L sound of the response voice is reproduced. On the other hand, the second reproduction device reproduces the R sound among the response sounds associated with the response image reproduced by itself. Alternatively, the second reproduction device mixes and reproduces both the L sound and the R sound of the response sound associated with the response image reproduced by itself.
Therefore, there is an effect that the sound from the left side is emphasized for the user who uses the second playback device. Even if only one speaker is connected to the playback device, pseudo stereo playback is possible if the left neighbor is performing demo playback.

The first playback device may be arranged on the right side of the second playback device.
The audio associated with the second response image includes left audio that should be output from the left side of the user of the second playback device and right audio that should be output from the right side of the user of the second playback device. It may be.
(Q3) When the first display unit displays the first demo image and the second display unit displays the second response image, the first audio output unit outputs the right audio and the second audio output The unit may output left audio and / or right audio.

That is, the first playback device and the second playback device are arranged in this order from the right. The response voice includes an L sound created on the assumption that it is output from the left side of the listening point and an R sound created on the assumption that it is output from the right side of the listening point.
When the first playback device displays a demo image and the second playback device displays a response image, the first playback device is associated with the response image displayed by the second playback device instead of the demo sound. The R sound is reproduced from the response voice.
On the other hand, the second reproduction device reproduces the L sound among the response sounds associated with the response image reproduced by itself. Alternatively, the second reproduction device mixes and reproduces both the L sound and the R sound of the response sound associated with the response image reproduced by itself.
Therefore, there is an effect that the sound from the right side is emphasized for the user who uses the second playback device. Even if only one speaker is connected to the playback device, pseudo-stereo playback is possible if the right neighbor is performing demo playback.

When three playback devices are arranged so as to be adjacent to each other in series and only the central playback device displays a response image, if both playback devices are in the demo playback mode, the playback device on the left side will receive L A sound can be output, and an R sound can be output from the right adjacent playback device.
Therefore, even if only one speaker is connected to the playback device, the stereo playback device can perform complete stereo playback if both neighbors are performing demo playback.

FIG. 2 is a diagram for explaining a functional configuration of the playback apparatus 200. The playback device 200 includes a display unit 201 and an audio output unit 202.

FIG. 3 is a diagram for explaining the configuration of a playback system 300 configured by connecting playback devices 200 of the present invention (denoted as 200A, 200B, and 200C in the figure) to each other. The playback system 300 according to the present embodiment includes three playback devices 200 arranged adjacent to each other and connected to each other via a LAN (Local Area Network). However, the number of playback devices 200 constituting the playback system 300 may be two or more.

FIG. 4 is a diagram for describing a functional configuration of each playback device 200 that configures the playback system 300. Each of the

playback devices

200A, 200B, and 200C has an equivalent hardware configuration.
However, each playback device 200 does not necessarily execute the same game, for example, the playback device 200A executes a fighting game, the playback device 200B executes a baseball game, and the playback device 200C executes a mahjong game. Also good.

The game performed by the playback device 200 of the present embodiment includes a demonstration part that prompts the user to start the game and a game main part that the user plays. The playback device 200 displays an image of the demonstration part until the game is requested by the user. Further, the playback device 200 displays an image of the main part of the game after the game start is requested until the game ends.

The request is, for example, a request that prompts the user to press any button of the controller 105 and prompts the user to start the game.

FIG. 5A shows an example of a demonstration image (hereinafter referred to as “demo image”) 250 displayed on a monitor connected to the playback apparatus 200.
FIG. 5B shows an example of an image (hereinafter referred to as “response image”) 260 of the main game part displayed on a monitor connected to the playback device 200.
Both the demo image 250 and the response image 260 may be a moving image (movie) or a still image (picture).

The display unit 201 displays the demo image 250 or the response image 260 on the monitor. The CPU 101 and the image processing unit 108 cooperate to function as the display unit 201.

The CPU 101 causes the image processing unit 108 to reproduce the demo image 250 until a game start request is made from the user, and waits until a game start request is input. In addition, after the game start request is made by the user, the CPU 101 starts the game and causes the image processing unit 108 to reproduce the response image 260.
When the CPU 101 receives an operation instruction from the user, the CPU 101 generates an image changed based on the received operation instruction, and reproduces the generated image as the response image 260.
When the game ends, the CPU 101 causes the image processing unit 108 to reproduce the demo image 250 again, and waits until a game start request is input.

The audio output unit 202 outputs a demo audio 270 corresponding to the demo image 250 or a response audio 280 corresponding to the response image 260. Demo voice 270 and response voice 280 are waveform data created in advance at a predetermined sampling rate. The CPU 101 and the audio processing unit 109 cooperate to function as the audio output unit 202.

That is, the CPU 101 reproduces the demo image 250 and the demo sound 270 until the game start request is made by the user. Before starting the game, the user can view images and sounds such as operation explanations using the demo image 250 and the demo sound 270.

In addition, after the game start request is made by the user, the CPU 101 reproduces the response image 260 and the response sound 280. After the game starts, the user can view the game image and sound based on the response image 260 and the response sound 280, which proceed according to the user's instruction (so-called “command”).

The demo image 250, the response image 260, the demo sound 270, and the response sound 280 are stored in advance in a DVD-ROM or the like. The CPU 101 reads these data from a DVD-ROM or the like as appropriate and reproduces the data by decoding it with a predetermined algorithm.

The CPU 101 basically reproduces the demo image 250 and the demo sound 270 corresponding to the demo image 250 or the response image 260 and the response sound 280 corresponding to the response image 260 in combination. However, for example, as shown in FIG. 3, when the playback devices 200 are connected so as to be adjacent to each other, the CPU 101 responds to the demo image 250 and the response image 260 that is being played back by another playback device 200. 280 may be combined and played back.

The user of the playback device 200B can listen to sound output from two directions.

Generally, the case 3-1 and the case 3-2 indicate that “three or more playback devices 200 are arranged, and two adjacent playback devices 200 play back their own response images 260, and the remaining playback devices 200 Corresponds to “when 200 plays the demo image 250”.

<Case 3-3>
When the

playback devices

200A and 200C play back the response image 260:
That is, the first user is playing the game using the leftmost playback device 200A, the second user is playing the game using the rightmost playback device 200C, and the remaining playback devices 200B are empty. is there.
The CPU 101 of the playback device 200A plays back the response image 260A and the response sound 280A. The CPU 101 of the playback device 200B plays back the demo image 250B and plays back the response sound 280A corresponding to the response image 260A or the response sound 280C corresponding to the response image 260C. The CPU 101 of the playback device 200C plays back the response image 260C and the response sound 280C.

The CPU 101 of the playback device 200B arranged in the middle plays back one of the response sound 280A of the playback device 200A on the left and the response sound 280C of the playback device 200C on the right.
For example, the CPU 101 of the playback device 200B randomly selects either the playback device 200A or the playback device 200C, and plays back the selected response voice (response voice 280A or response voice 280C).

For example, the CPU 101 of the playback device 200B plays back the response sound (response sound 280A or response sound 280C) of the playback device 200A and the playback device 200C that has the earlier game start request.

Therefore, the sound of the game executed on the playback device 200A may be output not only from the speaker connected to the playback device 200A but also from the speaker of the playback device 200B on the right.
The user of the playback device 200A may be able to listen to sound output from two directions. Alternatively, the sound of the game executed on the playback device 200C may be output not only from the speaker connected to the playback device 200C but also from the speaker of the playback device 200B adjacent to the left. The user of the playback device 200C may be able to listen to sound output from two directions.

Alternatively, the CPU 101 may reproduce a sound obtained by synthesizing the response sound 280A of the playback device 200A on the left side and the response sound 280C of the playback device 200C on the right side at a predetermined mixing ratio.

Therefore, the sound of the game executed on the playback device 200A is output not only from the speaker connected to the playback device 200A but also from the speaker of the playback device 200B on the right.
The user of the playback device 200A can listen to sound output from two directions. Similarly, the sound of the game executed on the playback device 200C is output not only from the speaker connected to the playback device 200C but also from the speaker of the playback device 200B adjacent to the left. The user of the playback device 200C can listen to sound output from two directions.

In general, in case 3-3, “three or more playback devices 200 are arranged side by side, two playback devices 200 that are not adjacent to each other play back their own response images 260, and other playback devices 200 display demo images. Corresponds to “when 250 is played”.

<Case 4>
When all the playback devices 200 play back the response image 260:
That is, all the

playback devices

200A, 200B, and 200C are in a state where a game is being played by the user.
The CPU 101 of the playback device 200A plays back the response image 260A and the response sound 280A. The CPU 101 of the playback device 200B plays back the response image 260B and the response sound 280B. The CPU 101 of the playback device 200C plays back the response image 260C and the response sound 280C.

Each user of the

playback devices

200A, 200B, and 200C will hear the sound of the game that they are playing from the playback device that they are using.

Next, playback processing executed by each unit of the playback device 200 according to the present embodiment will be described with reference to the flowchart of FIG. Here, it is assumed that a plurality of playback devices 200 that execute a game are installed adjacent to each other. The playback device 200 displays a demo screen 250 on the monitor immediately after power-on, and outputs a demo sound 270 from the speaker.

As described above, the playback device 200 changes the combination of the demo image 250, the response image 260, the demo sound 270, and the response sound 280, and plays back.
Information indicating which of the demo image 250 and the response image 260 is being reproduced and which of the demo sound 270 and the response sound 280 is being reproduced will be referred to as a “reproduction state”.
There are the following three playback states.

(Pattern 1) The response image 260 and the response sound 280 are combined and reproduced.
(Pattern 2) The demo image 250 and the response sound 280 are combined and reproduced.
(Pattern 3) The demo image 250 and the demo sound 270 are combined and reproduced.

First, the CPU 101 of the playback device 200 determines whether or not there is a request for starting a game from the user (step S701).

When it is determined that there is a request to start the game (step S701; YES), the CPU 101 ends the reproduction of the demo image 250 and reproduces the response image 260 (step S702). In addition, the CPU 101 ends the reproduction of the demonstration sound 270 and starts the reproduction of the response sound 280 (step S703).
That is, the image displayed on the monitor is switched from the demo image 250 to the response image 260, and the sound output from the speaker is switched from the demo sound 270 to the response sound 280. At this time, the playback state of the playback device 200 is the pattern 1 described above.

If it is determined that there is no request to start the game (step S701; NO), the CPU 101 continues to reproduce the demo image 250 (step S704).

The CPU 101 acquires the playback state of another adjacent playback device 200 (step S705). That is, the CPU 101 determines which one of the reproduction states of the patterns 1 to 3 is in the other adjacent reproduction device 200.

For example, the CPU 101 transmits a first message (typically packet data) for inquiring which pattern the playback state is to the other playback device 200 adjacent to. In response to the first message, the CPU 101 of the playback device 200 that has received the first message transmits a second message indicating its playback state. The CPU 101 of the playback device 200 that has received the second message can acquire the playback state of the other playback device 200 adjacent thereto.

When there are a plurality of adjacent playback devices 200, the CPU 101 may transmit and receive the first message and the second message to and from each of the adjacent playback devices 200.

Alternatively, when the playback state of the CPU 101 changes, the CPU 101 may transmit a message indicating that the playback state of itself has changed to another playback device 200 adjacent thereto. Then, the playback device 200 that has received this message may temporarily store the playback state of another playback device 200 adjacent to the RAM 103 or the like.
For example, when its own playback state changes from pattern 3 to pattern 1, CPU 101 transmits a message indicating that the playback state has changed from pattern 3 to pattern 1 to another adjacent playback device 200. The playback device 200 that has received this message can immediately recognize that the game has been started by the user in another playback device 200 adjacent thereto.
In this way, each playback device 200 can acquire the latest playback state of another playback device 200 adjacent thereto.

As shown in FIG. 8, the playback apparatus 200 displays mapping information 800 indicating whether or not there is another playback apparatus 200 next to itself or which playback apparatus 200 is placed next to itself. It is desirable to store in advance in the memory 106 or the like so that it can be appropriately rewritten. For example, the user can rewrite the mapping information 800 when the arrangement of the playback apparatus 200 is changed.

Returning to FIG. 7, the CPU 101 determines whether or not another adjacent playback device 200 is playing back the response image 260 based on the playback state acquired in step S <b> 705 (step S <b> 706).

When it is determined that the other adjacent playback device 200 is not playing back the response image 260, that is, when it is determined that the other playback device 200 is playing back the demo image 250 (step S706; NO). The CPU 101 reproduces the demo sound 270 corresponding to the demo image 250 being reproduced by itself (step S707). At this time, the playback state of the playback device 200 is the pattern 3 described above.

When it is determined that the other adjacent playback device 200 is playing back the response image 260 (step S706; YES), the CPU 101 responds corresponding to the response image 260 played back by the other playback device 200 adjacent to it. The voice 280 is acquired (step S708).

If the CPU 101 determines YES in step S706, the CPU 101 requests the other playback device 200 to transmit the waveform data indicating the response sound 280, and the CPU 101 of the other playback device 200 that has received this request. However, the response voice 280 may be transmitted in response to this request.
Further, the CPU 101 may store waveform data indicating the response sound 280 of another adjacent playback device 200 in the external memory 106, the RAM 103, or the like in advance.

Then, the CPU 101 reproduces the response voice 280 acquired in step S708 (step S709). At this time, the reproduction state of the reproduction apparatus 200 is the pattern 2 described above.

That is, in the case of YES in step S706, the playback device 200 displays the demo image 250 of the playback device 200 itself on the monitor and outputs the response sound 280 of the other playback device 200 adjacent from the speaker.
In other words, the user of another adjacent playback device 200 can hear the sound of the game being played from both the speaker at the own seat and the speaker of the adjacent playback device 200 while watching the screen of the game being played on the monitor at his seat. It will be.

According to the present embodiment, the playback device 200 can obtain various acoustic effects even when the number of connected speakers is small.
For example, in a playback system 300 in which two or more playback devices 200 are arranged side by side, a user can listen to more powerful sound when his / her neighbor is empty.

Each user of the

playback devices

The flow of playback processing executed by each unit of the playback device 200 of this embodiment is basically the same as that of the above embodiment. There are the following three patterns in the playback state of this embodiment.

(Pattern 13) A response image 260, a synthesized sound of its own response voice 280FL and response voice 280BL, and a synthesized sound of its own response voice 280FR and response voice 280BR are reproduced in combination.
(Pattern 14) The demo image 250 and the synthesized sound of the response sound 280BL and the response sound 280BR of the other playback device 200 are reproduced in combination.
(Pattern 15) The demo image 250 and the demo sound 270 are combined and reproduced.

This embodiment can be easily combined with the first to third embodiments.
For example, as shown in FIG. 13, the playback devices 200A to 200H constituting the playback system 300 may be arranged so as to be adjacent to each other on the left and right and adjacent to the front and rear.
“Arranged next to each other in the front-and-rear direction” means that the front faces each other across the passage 1300 so that the game housing is typically arranged at the game center.

For example, in a game center where a plurality of playback devices 200 (casing) are installed as shown in FIG. 13, when a user inserts a coin into any of the playback devices 200 (for example, 200B), it is displayed on the playback device 200. The image is switched from the demo image 250 to the response image 260.
If any of the other adjacent playback devices 200 (for example, 200A, 200C, 200F) is vacant, the response sound 280 is not only for the playback device 200 (for example, 200B) in which a coin has been inserted, Also output from the playback device 200 (for example, 200A and / or 200C and / or 200F). The user can play the game while listening to powerful sound. The more empty seats there are, the more powerful you can listen to.
When all the other playback devices 200 adjacent to each other are already in use by other users, the own response sound 280 is output only from the playback device 200 in which a coin is inserted.

(Embodiment 5)
Next, other embodiments of the present invention will be described. In this embodiment, the response sound 280 is composed of a plurality of part sounds. When the demo image 250 is being played back and another adjacent playback device 200 plays back the response image 260, the playback device 200 and the other adjacent playback device 200 share the response audio 280 part. To play. This will be described in detail below.

As shown in FIG. 14, the response voice 280 of this embodiment is composed of one or a plurality of parts. The parts are divided into musical instruments such as guitar sounds, piano sounds, drum sounds, and the like. In the DVD-ROM, waveform data divided for each musical instrument is stored in advance.

Further, the parts may be divided into main melody and sub melody, and waveform data of each melody may be stored in the DVD-ROM. In the DVD-ROM, waveform data divided for each melody may be stored in advance.

That is, the response sound 280 includes a first type of response sound to be reproduced by the playback device 200 itself and a second type of response sound to be reproduced by another adjacent playback device. The method for distinguishing between the first type and the second type is arbitrary. For example, the sound to be reproduced near the user can be assigned to the first type, and the other sounds can be assigned to the second type.

In the above embodiment, either the left response voice 280L or the right response voice 280R may be classified as the first type, and the other may be classified as the second type. In addition, either the front response voice or the rear response voice in the above embodiment may be classified as the first type, and the other may be classified as the second type.

15 and 16 are flowcharts for explaining the reproduction processing in the present embodiment. Here, it is assumed that the playback device 200 is a jukebox that plays music using a plurality of musical instruments. The response voice 280 is composed of a plurality of waveform data divided for each musical instrument.

First, the CPU 101 of the playback device 200 determines whether or not there is a request from the user to start playing music (step S1501).

If there is no request from the user (step S1501; NO), the CPU 101 repeats the process of step S1501. For example, the CPU 101 reproduces the demo screen 250.

When there is a request from the user (step S1501; YES), the CPU 101 transmits a message for inquiring the reproduction state to the adjacent reproduction device (step S1502). The CPU 101 of the playback device 200 that has received the message for inquiring the playback state notifies the playback state in response to this message (step S1503).

The CPU 101 acquires the playback state of the adjacent playback device, and determines the sharing of the response sound 280 based on the acquired playback state (step S1504).

For example, when the adjacent playback device is not playing back the demo screen 250, that is, when playing back its own response screen 260, the CPU 101 plays back the waveform data of all the parts constituting the response voice 280. Decide.

For example, when the adjacent playback device is playing the demo screen 250, the CPU 101 is responsible for playing the waveform data corresponding to the main melody in the response voice 280 and playing the waveform data corresponding to the sub melody. The sharing of the response sound 280 is determined such that the adjacent playback device is in charge.

For example, when the adjacent playback device is playing back the demo screen 250, the CPU 101 randomly selects one or more parts from the response voice 280, and plays back the waveform data corresponding to the selected part. The playback apparatus is in charge and the sharing is determined so that the waveform data corresponding to the remaining parts is played back.

For example, when the adjacent playback device is playing back the demo screen 250, the CPU 101 selects the sub melody portion of the response voice 280, and reproduces the waveform data corresponding to the selected sub melody portion. The playback device is in charge, and the sharing is determined so that the waveform data corresponding to the main melody part is in charge of playback.

When the adjacent playback device is not playing back the demo screen 250 (step S1505; NO), the CPU 101 proceeds to step S1601 described later.

When the adjacent playback device is playing back the demo screen 250 (step S1505; YES), the CPU 101 transmits the sharing result determined in step S1504 to the adjacent playback device (step S1506).

The CPU 101 of the adjacent playback device receives the sharing result (step S1507), and acquires the waveform data of the response voice 280 that it is in charge of (step S1508).

Next, the CPU 101 of the playback device 200 notifies the adjacent playback device of the start of playback of the response sound 280 (step S1509).

Then, the CPU 101 starts reproduction of the response image 260 (step S1510), and starts reproduction of the waveform data of the part shared by itself among the response sound 280 corresponding to the response image 260 (step S1511).

Further, the CPU 101 of the adjacent playback device starts playback of the waveform data acquired in step S1508 (step S1512).

Note that the reproduction start timing in step S1511 and the reproduction start timing in step S1512 are the same.
Further, it is desirable that the reproduction start timing of the response image 260 in step S1510 and the reproduction start timing of the response sound 280 in steps S1511 and S1512 are the same.

The CPU 101 determines whether or not the reproduction of the response voice 280 is finished (step S1513).
For example, the CPU 101 determines that the reproduction is to be ended if the pointer indicating the address currently being reproduced among the waveform data of the part for which the CPU 101 is in charge indicates the end of the waveform data, and does not end the reproduction otherwise. Is determined.
Alternatively, for example, the CPU 101 determines that the reproduction is to be ended when a request to stop the reproduction is received from the user, and determines that the reproduction is not to be ended otherwise.

When it is determined that the reproduction is not finished (step S1513; NO), the CPU 101 continues the reproduction of the response voice 280.

When it is determined that the reproduction is to be terminated (step S1513; YES), the CPU 101 notifies the adjacent reproduction device of the completion of the reproduction of the response sound 280 (step S1514), and the reproduction of the response sound 280 is terminated (step S1515).

Further, when the CPU 101 of the adjacent playback device receives the playback end notification, the playback of the response voice 280 is ended (step S1516).

Note that the playback end timing in step S1511 and the playback end timing in step S1512 are the same.
Further, it is desirable that the reproduction end timing of the response image 260 in step S1514 and the reproduction end timing of the response sound 280 in steps S1515 and S1516 are the same.

Next, when it is determined in step S1505 that the adjacent playback device is not playing back the demo image 250 (step S1505; NO), the CPU 101 starts playback of the response image 260 (step S1601) and the response sound 280. Is started (step S1602).
It is desirable that the reproduction start timing of the response image 260 in step S1601 and the reproduction start timing of the response sound 280 in step S1602 are the same.

The CPU 101 determines whether or not the reproduction of the response voice 280 is finished (step S1603).
For example, the CPU 101 determines that the reproduction is to be ended if the pointer indicating the address currently being reproduced among the waveform data of the part for which the CPU 101 is in charge indicates the end of the waveform data, and does not end the reproduction otherwise. Is determined.
Alternatively, for example, the CPU 101 determines that the reproduction is to be ended when a request to stop the reproduction is received from the user, and determines that the reproduction is not to be ended otherwise.

When it is determined that the reproduction is not finished (step S1603; NO), the CPU 101 continues the reproduction of the response voice 280.

When it is determined that the reproduction is to be ended (step S1603; YES), the CPU 101 ends the reproduction of the response voice 280 (step S1604) and returns to step S1501.

According to the present embodiment, when the adjacent playback device is playing back the demo image 250, that is, when the adjacent playback device is not used by the user, the user of the playback device 200, for example, from his playback device 200 Sounds can be heard not only from the speakers of the playback apparatus 200 but also from the speakers of the playback apparatus 200 in the adjacent empty seat, such that the sound of the guitar and piano can be heard and the sound of the drum of the same music can be heard from the adjacent playback apparatus 200. I can hear you. The user of the playback device 200 can obtain various sound effects even when only one speaker is connected.

For example, when the division is determined such that the adjacent reproduction device is in charge of reproducing the waveform data corresponding to the randomly selected musical instrument and the waveform data corresponding to the remaining musical instruments is in charge of the reproduction of the waveform data. Even when the operation status of the adjacent playback device does not change, the place where the sound of the instrument sounds changes, so various variations are added to the way the sound is heard and the interest is enhanced.

Although the present embodiment has been described on the assumption that there is one adjacent playback device, when there are a plurality of adjacent playback devices, the waveform data that constitutes the response sound 280 in each adjacent playback device. Can be shared.
For example, when three playback devices 200 are arranged side by side, and only one of the playback devices 200 plays the response image 260, the first playback device 200 takes charge of the guitar, and the second playback device 200 It is possible to freely share the reproduction of the waveform data constituting the response voice 280 such that the piano is in charge and the third playback device 200 is in charge of the drum.

The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. Moreover, it is also possible to freely combine the constituent elements of the above-described embodiments.

A program for operating a computer as all or part of the playback device 200 is stored in a computer-readable recording medium such as a memory card, CD-ROM, DVD, or MO (Magneto Optical disk) and distributed. It may be installed in another computer and operated as the above-described means, or the above-described steps may be executed.

Furthermore, the program may be stored in a disk device or the like of a server device on the Internet, and may be downloaded onto a computer by being superimposed on a carrier wave, for example.

As for the present application, the priority based on Japanese Patent Application No. 2008-313906 is claimed and all the contents of the basic application are incorporated in the present application.

As described above, according to the present invention, it is possible to provide a playback device, a playback system, a playback method, an information recording medium, and a program suitable for easily outputting sound with enhanced acoustic effects.
