  A karaoke device is a device with audio output. Karaoke singing is used in various forms at various locations. For example, karaoke singing is performed in a form (night store) as shown in FIG. In the store shown in FIG. 1, a counter, a small room 1, a small room 2, and a small room 3 are provided. A commander and amplifier for playing karaoke music are provided around the counter. Each small room is a simple private room partitioned by partitions. Each small room is provided with a speaker and a display. There are a plurality of remote controllers in the store, and a music selection signal (request signal) is transmitted to the commander.

  In such a store, an amplifier is provided so that the reproduction sound of the karaoke music is output only to the speaker in the small room where the karaoke song is performed, and the reproduction sound is not output to the speaker in other places (other small rooms, etc.). Switch the output destination. Thereby, in a small room or the like where the playback sound of the karaoke music is not output, the playback sound is leaked and can be enjoyed.

  Here, when the playback sound output is switched manually (amplifier switching), it is conceivable that a mistake such as switching not in time or incorrect switching occurs. Therefore, a karaoke system that performs the switching operation is desired. The technique disclosed in Patent Document 1 cannot realize a karaoke system that performs the switching operation.

  In the above-described store, when the number of remote controllers is smaller than the number of counters and small rooms, one remote controller is taken out and used in a plurality of small rooms. Since the remote control can perform operations (for example, volume adjustment, playback stop, etc.) on the karaoke song being played back, in a small room where karaoke singing is not being performed, There is a risk of incorrect operation. If such operation is performed, it will give discomfort to the user who is performing karaoke singing.

  The present invention has been made to solve the above-described problems, and provides a karaoke system for selecting a speaker that appropriately selects and outputs a reproduction sound of karaoke music, a remote controller for karaoke used in the karaoke system, and the like. With the goal.

In addition, since the infrared rays output from the respective infrared light emitting units have different properties, the remote controller 200 can recognize the position of the own device by identifying the properties of the received infrared rays.
Moreover, you may comprise so that each infrared light emission part may be installed in each table and a counter instead of a ceiling.

Next, details of the commander 100 and the remote controller 200 will be described.
FIG. 3 shows an example of the configuration of the commander 100 and the remote controller 200. 3 shows a one-to-one relationship between the commander 100 and the remote controller 200, but in the present embodiment, a plurality of remote controllers 200 can communicate with one commander 100.

  The commander 100 basically includes a communication interface (I / F) 111, a CPU 112, a ROM 113, a RAM 114, an auxiliary storage unit 115, a video / audio reproduction unit 116, an amplifier 117, and a selection unit 120.

  The remote controller 200 basically includes a communication interface (I / F) 211, a CPU 212, a ROM 213, a RAM 214, a display unit 215, an operation unit 216, and an infrared light receiving unit 217.

The communication I / F 111 and the communication I / F 211 are interfaces for the commander 100 and the remote controller 200 to perform wireless communication using radio waves as a medium. In the present embodiment, an operation instruction signal or the like for the commander 100 is transmitted from the remote controller 200 to the commander 100. Various signals are transmitted from the commander 100 to the remote controller 200. Information may be transmitted and received via an access point (not shown).
Further, by using the communication I / F 111 and the communication I / F 211, it is also possible to transmit and receive various information to and from a host (not shown).

  Here, when the commander 100 and the remote controller 200 are connected by Ethernet (registered trademark) or the like, a unique IP address is assigned to each device. Further, the IP address can be calculated based on an identification number described later and a predetermined generation formula.

  The CPU 112 and the CPU 212 execute various programs including a program (described later) necessary for realizing the present embodiment. The ROM 113 and the ROM 213 store various data including information necessary for realizing the present embodiment. The RAM 114 and RAM 214 temporarily store various data including information necessary for realizing the present embodiment. The RAM 114 stores a reservation table (described later). The RAM 214 has a first area (described later) and a second area (described later).

The auxiliary storage means 115 stores, for example, audio data and video data necessary for reproducing karaoke music. In addition, application data such as a game is stored.
The video / audio reproduction means 116 reproduces karaoke music and video. It is also possible to perform streaming playback based on data transmitted from a host (not shown).

  The video / audio reproduction means 116 is connected to the amplifier 117, the amplifier 117 is connected to the selection means 120, and the selection means 120 is connected to each speaker (see FIG. 2). The connection relationship between the commander 100 and each speaker will be described later.

  Further, voice input means (such as a microphone) and monitors 321 to 324 (not shown) are connected to the commander 100. The commander 100 may have a scoring function.

The remote controller 200 is provided with a display unit 215. The display unit 215 displays various information including information necessary for realizing the present embodiment. Display control of the display unit 215 will be described later.
The operation unit 216 receives user operations (request operation, volume operation, etc.), and can be realized as a touch panel on the surface of the display unit 215.

  The infrared light receiving unit 217 receives the infrared light output from the infrared light emitting units 331 to 334. Since each of the infrared rays output from the infrared light emitting units 331 to 334 has different properties, the remote controller 200 can recognize from which infrared light emitting unit the received infrared rays are output.

Next, the connection relationship between the commander 100 and each speaker will be described. FIG. 4 is a schematic diagram showing the connection relationship between the commander 100 and each speaker.
The selection unit 120 controls the connection relationship between the amplifier 117 and each speaker based on a control signal output from the CPU 112.

  As shown in FIG. 4, the audio signal output from the video / audio reproduction means 116 is output to the amplifier 117. The amplifier 117 is connected to the selection unit 120. The selection unit 120 includes switches 121 to 124, and ON / OFF control of each switch is performed based on a control signal output from the CPU 112.

  When the switch 121 is turned on, the audio signal from the amplifier 117 is output from the speaker 311. When the switch 122 is turned on, the audio signal from the amplifier 117 is output from the speaker 312. When the switch 123 is turned on, the amplifier 117 When the switch 124 is turned on, the audio signal from the amplifier 117 is output from the speaker 314.

  Next, the flow of information between the infrared light emitting unit, the remote controller, and the commander will be described. FIG. 5 is a diagram illustrating a flow of information between the infrared light emitting unit, the remote controller, and the commander.

The infrared light emitting units (331 to 334) output infrared rays at predetermined time intervals (1).
When receiving the infrared rays, the remote controller 200 updates the first area of the RAM 214 (2). Specifically, the remote controller 200 identifies the property of the infrared ray, and stores information based on the identified property in the first area of the RAM 214. Hereinafter, information stored in the first area is referred to as current position information. The current position information indicates the current position of the remote controller 200.

  For example, “SP1” is received when infrared light is received from the infrared light emitting unit 331 of the small room 801, and “SP2” is received when infrared light is received from the infrared light emitting unit 332 of the small room 802, and infrared light is emitted from the small room 803. “SP3” is stored as the current position information when infrared is received from the unit 333 and “SP4” is stored when received from the infrared light emitting unit 334 around the counter 804.

  Here, the processes (1) and (2) described above are repeatedly executed at predetermined intervals. Accordingly, the remote controller 200 can recognize the position of the own device by referring to the first area.

The remote controller 200 is operated by the user to perform a request operation (an operation for inputting an identification number of a karaoke song to be sung, a song title corresponding to an identification number of a karaoke song to be sung by a “song name”, “singer name”, or “new music” button). The music selection number is specified, and an operation for inputting the music selection number with the “request reservation” button is accepted (3).
The remote controller 200 transmits a request signal to the commander 100 (4). Here, the request signal includes the received song selection number and the current position information (information stored in the first area of the RAM 214).

  When receiving the request signal, the commander 100 executes reservation acceptance processing (5). In the reservation acceptance process, the reservation table is updated. FIG. 6 is an example of the structure of the reservation table. The music selection number included in the request signal is stored as “music selection number” in the reservation table. The current position information included in the request signal is stored as “request position information” in the reservation table. Further, as shown in FIG. 6, the music selection number and the request position information are stored in pairs for each reservation order. FIG. 6 shows a state in which 19 reserved songs are stored. When the reserved karaoke music is played, the music selection number and request position information of the karaoke music are deleted from the reservation table.

The commander 100 transmits a start signal to each remote controller 200 when reproducing karaoke music (6). The start signal includes request position information corresponding to the music selection number of the karaoke music to be reproduced. For example, in FIG. 6, when the karaoke music piece with the music selection number “555” stored in the reservation order “1” is reproduced, the request position information “SP1” is included in the start signal. The commander 100 can transmit a start signal to each remote controller 200 by broadcast communication.
After transmitting the start signal, the commander 100 starts playing the karaoke music (7).

  When receiving the start signal, the remote controller 200 updates the second area of the RAM 214 (8). Specifically, the request location information included in the received start signal is overwritten in the second area. The request position information is information indicating where the karaoke music piece played back by the commander 100 is requested.

  The remote controller 200 performs a display control process during the reproduction of the karaoke music (9). Details of the display control process will be described later.

  When the commander 100 finishes the reproduction of the karaoke music piece, the commander 100 transmits an end signal to each remote controller 200 (10). The end signal includes information indicating that the reproduction of the karaoke music has ended. The commander 100 can transmit an end signal to each remote controller 200 by broadcast communication.

  When receiving the end signal, the remote controller 200 updates (clears) the second area of the RAM 214 (11).

Next, remote control normal processing executed by the remote controller 200 will be described. The remote control normal process is repeatedly executed by the CPU 212 at a predetermined cycle.
FIG. 7 is a flowchart of the remote control normal process.

  In S11, it is determined whether or not infrared rays are received. When it is determined that infrared rays are not received (S11: NO), the process proceeds to S13. On the other hand, if it is determined that infrared rays have been received (S11: YES), the process proceeds to S12.

In S12, the first area of the RAM 214 is updated. Specifically, the nature of the received infrared ray is identified (that is, the infrared ray output from which infrared light emitting portion is identified), and the place where the infrared ray is output (small room 801 to 803 or counter 804) And the information (any one of “SP1” to “SP4”) indicating the location is overwritten in the first area of the RAM 214.
If it is determined that the received infrared light is output from other than the infrared light emitting units 331 to 334, the process of S12 is not executed.

In S13, it is determined whether a request operation has been accepted. If it is determined that the request operation has not been accepted (S13: NO), the process proceeds to S15.
On the other hand, if it is determined that the request operation has been received (S13: YES), the process proceeds to S14. In S14, a request signal is transmitted to the commander 100. Here, the request signal includes “the identification number of the karaoke song accepted in S13” and “current position information”.

In S15, it is determined whether a start signal is received from the commander 100 or not. When it is determined that the start signal has not been received (S15: NO), the process proceeds to S17.
On the other hand, when it is determined that the start signal has been received (S15: YES), the process proceeds to S16.
In S16, the second area of the RAM 214 is updated. Specifically, the request position information included in the received start signal is overwritten in the second area of the RAM 214.

In S17, it is determined whether an end signal is received. If it is determined that the end information has not been received (S17: NO), the process returns to S11.
On the other hand, if it is determined that the end signal has been received (S17: YES), the process proceeds to S18.
In S18, the second area of the RAM 214 is updated. Here, the second area is cleared. The predetermined flag information may be written in the second area.

  Next, display control processing executed by the remote controller 200 will be described. The display control process is repeatedly executed by the CPU 212 at a predetermined cycle. The display control process is executed in parallel with the above-described remote control normal process. FIG. 8 is a flowchart of the display control process.

In S21, the current position information is acquired from the first area of the RAM 214.
In S22, request position information is acquired from the second area of the RAM 214.
In S23, it is determined whether or not the current position information matches the request position information. If it is determined that both pieces of information match (S23: YES), the process proceeds to S24.

The current position information acquired in S21 indicates the current location of the remote controller 200, and the request position information acquired in S22 indicates the location where the playback sound of the karaoke song is output. , The remote controller 200 is present at the place where the playback sound of the karaoke music is output.
In S24, playback control options are displayed.

The process of S24 will be described in detail.
FIG. 9 is an example of the layout of the display unit 215, and shows a state in which playback control options are not displayed. As shown in FIG. 9, the display unit 215 displays various options (buttons) for accepting the request operation, but does not display options (buttons) for controlling the karaoke song being played. Absent.

  FIG. 10 is an example of the layout of the display unit 215, and shows a state in which playback control options are displayed. As shown in FIG. 10, in addition to various buttons for accepting a request operation, the display unit 215 includes operations for a karaoke piece being played (performance stop operation, replay operation, volume operation, key operation). Options (buttons) are displayed. When these options are operated, an operation based on the operated options is performed on the karaoke piece being played.

  Further, while the current position information and the request position information match, the process of S24 is repeatedly executed, so that a reproduction control option is displayed.

  By performing such control, an option for controlling the karaoke song being played back is when the remote control 200 is present at the place where the karaoke song being played is requested (where the sound is output from the speaker). Therefore, it is possible to prevent an operation on the karaoke song being played in another place not related to karaoke singing.

  For example, in FIG. 2, when the playback sound of the karaoke music requested in the small room 801 is output from the speaker 311 installed in the small room 801, when the remote controller 200 exists in the small room 801, The screen of FIG. 10 is displayed on the display unit 215. As a result, the user can operate the karaoke piece being played. On the other hand, when the remote controller 200 exists in the small room 802, the screen of FIG. 9 is displayed on the display unit 215. Thereby, although the user can perform a request operation, the user cannot perform an operation on the karaoke music piece being reproduced and output in the small room 801.

Returning to FIG.
If it is determined in S23 that the current position information does not match the request position information (S23: NO), the process proceeds to S25.
In S25, the reproduction control option is not displayed.

  In S26, it is determined whether a special operation is accepted. Here, examples of the special operation include “pressing a predetermined portion of the display unit 215 in a predetermined order”, “operation using a key switch”, “operation using a magnetic card”, “operation using an IC card”, and the like.

If it is determined that no special operation is accepted (S26: NO), the process returns to S21. On the other hand, if it is determined that a special operation has been accepted (S26: YES), the process proceeds to S27.
In S27, display / non-display of special options is controlled according to the received special operation. Further, the special option may be the same as the above-described reproduction control option, or may be other than that.

Next, the reservation acceptance process executed by the commander 100 will be described. The reservation acceptance process is repeatedly executed by the CPU 112 at a predetermined cycle. FIG. 11 is a flowchart of the reservation acceptance process.
In S31, it is determined whether a request signal has been received from any of the remote controllers 200. If it is determined that the request signal has not been received (S31: NO), the process returns to S31.

  On the other hand, if it is determined that the request signal has been received (S31: YES), the process proceeds to S32. In S32, the reservation table is updated. Specifically, a new row is added to the reservation table, and the music selection number and position information (request position information) included in the received request signal are added.

  Next, the music reproduction process executed by the commander 100 will be described. The music reproduction process is repeatedly executed by the CPU 112 at a predetermined cycle. Further, it is executed in parallel with the reservation reception process described above. FIG. 12 is a flowchart of the music playback process.

  In S41, it is determined whether or not a reserved song exists in the reservation table. If it is determined that there is no reserved song (S41: NO), the process proceeds to S42. In S42, a predetermined BGM is reproduced. At this time, the CPU 112 transmits a control signal for turning on the connected switches 121 to 124 to the selection unit 120. As a result, while no reserved music exists, a predetermined BGM is output from each speaker in all places (small rooms 801 to 803 and counter 804).

On the other hand, if it is determined that there is a reserved song (S41: YES), the process proceeds to S43.
In S43, a control signal is transmitted to the selection means 120. Specifically, first, a speaker for outputting sound is determined based on the request position information stored in the reservation order “1” in the reservation table. In addition, a control signal for outputting sound to the determined speaker is determined, and the control signal is transmitted to the selection unit 120.

  In S44, a start signal is transmitted to all remote controllers 200. The start signal includes the request position information acquired in S43.

In S45, the music selection number of the karaoke music to be reproduced is acquired with reference to the reservation table, and the karaoke music is reproduced. Also, the music selection number and request position information of the karaoke music to be reproduced are deleted from the reservation table.
During playback of karaoke music, the process waits in S45.

  When the reproduction of the karaoke music is completed, the process proceeds to S46, and an end signal is transmitted. The end signal includes information indicating that the reproduction of the karaoke music has ended.

As described above, according to the present embodiment, when the remote controller 200 receives a request operation (a karaoke song identification number) from the user, the remote controller 200 acquires the current position information of the own device, and gives the commander 100 the identification number and A request signal including the current position information is transmitted. The commander 100 stores the current position information as request position information. When the commander 100 plays the karaoke piece having the identification number, the commander 100 selects a speaker that outputs the reproduction sound of the karaoke piece to be played based on the request position information.
Thereby, in the place where karaoke singing is not performed, since the reproduction | regeneration sound of karaoke music is not output, it can prevent that the said reproduction | regeneration sound obstructs conversation etc.
Also, the remote controller 200 displays options for operation on the karaoke song being reproduced only when the karaoke song is present at the place where the sound is output.
Thereby, since it can prevent that operation with respect to the karaoke music being reproduced | regenerated is performed in the other place which is not related to karaoke singing, the discomfort of the user who is singing can be prevented.

  Note that each flowchart described above is merely an example, and the processing may be realized by another flowchart as long as a result equivalent to the processing of each flowchart can be obtained.

The present invention is not limited to the above-described embodiment, and it goes without saying that various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the above-described embodiment, with respect to the process in which the remote controller recognizes the position of its own device, the infrared light receiving unit is provided in the remote control and the infrared light emitting unit is provided outside the remote control. It is good also as a structure which provides and an infrared rays light-receiving part outside the remote control (for example, each table etc.).

In this case, when the remote controller outputs infrared rays (assuming that the identification number of the remote controller is included), the infrared rays are received by an infrared light receiving unit installed around the remote controller. Since each infrared light receiving unit is connected to the commander, the commander can identify “a remote control that emits infrared light” and “an infrared light receiving unit that receives the infrared light”. Then, the commander transmits position information corresponding to the “infrared light receiving unit that receives the infrared rays” to the “remote control that emits infrared rays”.
Even in such a configuration, the remote controller can recognize the position of the own device.

Even if each infrared light receiving unit is installed on each table, each infrared light receiving unit can receive infrared light from the infrared light emitting unit, so that the remote controller can recognize the position of the own device.
Also, instead of using infrared communication technology, the remote control's own device can be used by using communication technology that uses weak radio waves that do not interfere (for example, Bluetooth (trademark) class 3 or communication that complies with the regulations of weak radio stations). The position may be recognized.

  That is, the karaoke system according to the present invention can be realized as various forms including a transmission unit that emits a signal such as infrared rays and a reception unit that receives the signal. Further, the transmitting unit and the receiving unit may be arranged at any position as long as signals can be transmitted and received, and may be realized as a part of the functions of the remote controller and / or the commander described above. . Further, the configuration for identifying the nature of the signal such as infrared rays may be arranged at any position as long as the nature of the signal can be identified, and the functions of the remote control and / or the commander described above may be used. It may be realized as a part.

  The present invention can also be realized as the above-described karaoke system, a method in the karaoke remote control, a program for realizing the method, and a recording medium on which the program is recorded.
