  The present invention relates to a technique for associating a karaoke device that plays karaoke music with an operation terminal for remotely operating the karaoke device.

  Patent Document 1 discloses a technique that enables a karaoke apparatus to be operated by an associated operation terminal by associating an operation terminal such as a karaoke apparatus and an electronic quick sample apparatus as a specific communication partner (also referred to as an association). Have been described. With such a technique, in a LAN (Local Area Network) to which a plurality of karaoke apparatuses are connected, an operation terminal and an operation target karaoke apparatus can be appropriately associated with each other.

JP 2006-78759 A

  By the way, in a karaoke store where a large number of karaoke devices are installed, karaoke devices composed of a plurality of different models may be mixed in a LAN in the karaoke store. In such an environment, an operation may be performed in which communication between karaoke apparatuses of different models is restricted by constructing subnets with a plurality of address spaces for each model of karaoke apparatus in one LAN.

  For example, in a network (IP network) environment using the Internet protocol, a different subnet is assigned to each model of karaoke apparatus by setting a network address. On the other hand, conventionally, the operation terminal has a unique IP address corresponding to the address system of the network that is a communication connection destination, thereby enabling communication with a karaoke apparatus connected to the network.

  For this reason, if multiple subnets are constructed for each karaoke machine model in the network that is the communication connection destination of the operation terminal, multiple types of operation terminals must be prepared for each subnet to which each karaoke machine model belongs. did not become. On the other hand, in order to enable selective communication with each type of karaoke apparatus belonging to each subnet with one type of operation terminal, the operation terminal has a unique IP address corresponding to each of the plurality of subnets. There is a need. However, such an IP address management method is inefficient because one operating terminal occupies many IP addresses.

  The present invention has been made to solve the above problems. An object of the present invention is to dynamically assign an address according to the subnet to which the karaoke device belongs to an operation terminal that selectively remotely operates a karaoke device that belongs to a plurality of different subnets in the network. It is to provide technology that can be used efficiently.

The karaoke system of the present invention has a karaoke device connected to a network in which subnets by a plurality of address spaces are constructed, an operation terminal for remotely operating the karaoke device via the network, and a karaoke device to be operated Is a karaoke system for associating as a specific communication partner, and includes an acquisition means, an association information recording means, and an assignment means.

  An acquisition means acquires the terminal identification information which identifies an operation terminal, and the address of a karaoke apparatus about the karaoke apparatus matched with a specific communication other party, and an operation terminal. The association information recording unit records the terminal identification information of the operation terminal acquired by the acquisition unit in association with the address of the karaoke apparatus in the storage unit. The allocating means determines a communicable address with respect to the address of the karaoke apparatus based on the terminal identification information of the operation terminal and the address of the karaoke apparatus stored in association with each other in the storage means, and determines the determined address as the terminal Assigned to the operation terminal corresponding to the identification information.

  In this way, according to the address on the karaoke device side, the karaoke device associated with the specific communication partner and the operation terminal can reliably communicate with each other in a network in which a plurality of subnets are constructed. The address on the operation terminal side can be dynamically assigned. Therefore, it is not necessary to give the operation terminal a plurality of unique addresses respectively corresponding to a plurality of subnets, and the addresses can be used efficiently. In addition, since an address can be dynamically assigned to the operation terminal, it is easy to move the operation terminal to another network and use the karaoke apparatus connected to the network and the operation terminal in association with each other. .

  In addition, as an address given to the operation terminal associated with the karaoke device, as described in claim 2, an address assigned to the operation terminal corresponding to the terminal identification information is an address belonging to the same subnet as the address of the karaoke device. It can be considered. For example, in an IP network environment, a subnet is defined by a network address portion of an IP address. Therefore, the karaoke device and the operation terminal can be communicated with each other by assigning an IP address having a network address common to the IP address of the associated karaoke device to the operation terminal.

  As a specific configuration of the karaoke system of the present invention, it is conceivable to include an address lease server that dynamically assigns addresses to communication devices connected to a network. The karaoke apparatus includes terminal identification information acquisition means and transmission means. The terminal identification information acquisition means acquires terminal identification information of an operation terminal associated with itself as a specific communication partner. The transmission means transmits the terminal identification information acquired by the terminal identification information acquisition means and its own address to the address lease server. On the other hand, the address lease server includes acquisition means, association information recording means, and assignment means. The acquisition means acquires terminal identification information and an address transmitted from the karaoke apparatus.

  By the way, in order to associate a karaoke apparatus and an operation terminal as a specific communication partner, each of the karaoke apparatus and the operation terminal needs to grasp the address of the communication partner. Therefore, a configuration as described in claim 4 is preferable. That is, the address lease server notifies the karaoke apparatus associated with the operation terminal of the address assigned to the operation terminal by the assigning unit. The karaoke apparatus transmits an associated notification with its own address to the address of the operation terminal notified from the address lease server.

  In this way, the karaoke device is notified of the address assigned to the operation terminal, and the karaoke device notifies the operation terminal of its own address based on the notified address, so that the associated karaoke device and operation terminal Each can grasp the address of the communication partner. In this way, for example, for the purpose of notifying the communication partner whose address is unknown, there is no need to broadcast communication data with its own address in the network, and the communication load can be reduced.

The invention described in claim 5 relates to an address lease server that dynamically assigns addresses to communication devices connected to a network in a karaoke system that associates an operation terminal and a karaoke apparatus as a specific communication partner. The address lease server includes acquisition means, association information recording means, and assignment means.

  An acquisition means acquires the terminal identification information which identifies an operation terminal, and the address of a karaoke apparatus from a karaoke apparatus about the karaoke apparatus matched with a specific communication other party, and an operation terminal. The association information recording unit records the terminal identification information of the operation terminal acquired by the acquisition unit in association with the address of the karaoke apparatus in the storage unit. The allocating means determines a communicable address with respect to the address of the karaoke apparatus based on the terminal identification information of the operation terminal and the address of the karaoke apparatus stored in association with each other in the storage means, and the determined address is determined as the terminal identification information. Is assigned to the operation terminal corresponding to. According to the address lease server of the present invention, the same effect as that described for the karaoke system according to claim 1 can be obtained.

The infrared communication unit 29 is a communication interface that performs infrared communication with the remote control terminal 30 in accordance with a predetermined infrared communication standard using infrared as a medium.

  Returning to the description of the block diagram of FIG. In the present embodiment, the two karaoke apparatuses 20a (A model) and 20b (B model) are different from each other. Then, by setting the network address, the two karaoke apparatuses 20a and 20b are divided into different subnets, thereby restricting communication between different models.

  In the example of FIG. 1, the IP address of the karaoke apparatus 20a is 192: 168: 0: 2/24. The IP address of the karaoke apparatus 20b is 192: 168: 1: 2/24. In this case, the network addresses of the karaoke apparatuses 20a and 20b are 192: 168: 0 and 192: 168: 1, respectively, and the karaoke apparatuses 20a and 20b belong to different subnets. On the other hand, in order to enable the DHCP router 10 to communicate with both the karaoke apparatuses 20a and 20b, two types of IP addresses (192: 168: 0: 1/24, 192: 168: 1: 1/24) is assigned.

The remote control terminal 30 has a wireless communication function conforming to a well-known wireless LAN communication standard (for example, IEEE 802.11 standard), communicates with the LAN 50 via the wireless LAN access point 40, and has an infrastructure mode. Communication is performed with the karaoke apparatus 20 and the DHCP router 10 in the communication mode such as.

  As a premise for operating the karaoke device 20 with the remote control terminal 30, “binding” is performed in which the remote control terminal 30 and the karaoke device 20 to be operated are associated with each other as a specific communication partner. This binding is established by the karaoke apparatus 20 and the remote control terminal 30 storing each other's IP address. At this time, the DHCP router 10 assigns an IP address corresponding to the subnet to which the karaoke device 20 to be bound belongs to the remote control terminal 30 by wireless LAN communication via the wireless LAN access point 40.

  The wireless LAN access point 40 is a radio wave repeater for connecting terminals by wireless communication according to a predetermined wireless LAN standard. A plurality of wireless LAN access points 40 may be distributed and arranged in various places in the karaoke store. Note that the configuration of the wireless LAN access point 40 is the same as that of a well-known one, and a description thereof is omitted here.

[Explanation of binding process]
The procedure of the binding process performed by each device of the karaoke system will be described with reference to the sequence diagram of FIG. In FIG. 4, in S108, S112, S114, S116, S122, and S124, which will be described later, information is transmitted and received between the remote control terminal 30 and the DHCP router 10 or the karaoke apparatus 20 via the wireless LAN access point 40 and the LAN 50. (The expression that the line connecting the remote control terminal 30 and the DHCP router 10 or the karaoke device 20 does not intersect the wireless LAN access point 40). This expresses the result of information transmission performed between the remote control terminal 30 and the DHCP router 10 or the karaoke device 20, and actually between the remote control terminal 30 and the DHCP router 10 or the karaoke device 20. It is assumed that a wireless LAN access point 40 and a LAN 50 are used as transmission paths for performing communication in the network.

  In S100, a wireless connection is established between the remote control terminal 30 and the wireless LAN access point 40. In S <b> 102, the remote control terminal 30 transmits its own MAC address to the karaoke apparatus 20 using infrared communication. Here, by using infrared communication, it is possible to limit the partner linked to the remote control terminal 30 to a specific karaoke device 20 in the communicable range of infrared communication (for example, in the same karaoke room).

  In S <b> 104, the control unit 21 of the karaoke apparatus 20 sends an assignment rule registration request including the MAC address received from the remote control terminal 30 via the infrared communication unit 29 and the IP address assigned to itself to the DHCP router 10. Send. In S <b> 106, when receiving the allocation rule registration request from the karaoke apparatus 20, the control unit 11 of the DHCP router 10 updates the allocation rule (see FIG. 3) stored in the storage unit 13. Specifically, the control unit 11 of the DHCP router 10 associates the MAC address of the remote control terminal 30 included in the received allocation rule registration request with the IP address and subnet mask of the karaoke device, and stores it as an allocation rule. 13 is recorded.

  In S108, the remote control terminal 30 broadcasts DHCP DISCOVER, which is a message for searching for the DHCP router 10, to the LAN 50 via wireless LAN communication. This DHCP DISCOVER includes the MAC address of the own remote control terminal 30.

In S <b> 110, when receiving the DHCP DISCOVER from the remote control terminal 30, the control unit 11 of the DHCP router 10 determines an IP address to be assigned to the transmission source remote control terminal 30. Specifically, the control unit 11 of the DHCP router 10 refers to the allocation rule in the storage unit 13 and specifies the IP address and subnet mask of the karaoke apparatus 20 associated with the MAC address included in the DHCP DISCOVER. Then, the control unit 11 of the DHCP router 10 determines the I of the karaoke device 20 specified from the allocation rule.
An IP address that can be assigned to the remote control terminal 30 that is the transmission source is determined from the address space that belongs to the same subnet as the P address. In S <b> 112, the control unit 11 of the DHCP router 10 transmits DHCP OFFER, which is a message including the IP address determined in S <b> 110, as a response to the DHCP DISCOVER to the transmission source remote control terminal 30.

In S <b> 114, the remote control terminal 30 receives the DHCP transmitted from the DHCP router 10.
When OFFER is received, DHCP REQUEST, which is a message requesting assignment of the IP address provided from the DHCP router 10, is broadcast to the LAN 50 via wireless LAN communication.

  In S 116, when receiving the DHCP REQUEST transmitted from the remote control terminal 30, the control unit 11 of the DHCP router 10 sends a DHCP ACK that is a message including the IP address assigned to the transmission source remote control terminal 30 to the transmission source remote control terminal 30. Send to. In S118, when receiving the DHCP ACK from the DHCP router 10, the remote control terminal 30 stores the IP address included in the received DHCP ACK as its own IP address.

  In S120, the control unit 11 of the DHCP router 10 transmits an assignment completion notification including the IP address of the remote control terminal 30 to the karaoke device 20 associated with the remote control terminal 30 to which the IP address is assigned in S110 to S116. . Specifically, the control unit 11 of the DHCP router 10 sends the IP address of the remote control terminal 30 to the IP address of the karaoke device 20 associated with the MAC address of the remote control terminal 30 in the allocation rule of the storage unit 13. An assignment completion notification including is sent.

  In S122, when receiving the assignment completion notification transmitted from the DHCP router 10, the control unit 21 of the karaoke apparatus 20 stores the IP address included therein as the IP address of the binding partner, and the IP address of the binding partner A binding information notification including its own IP address is transmitted to the addressee. For example, UDP (User Datagram Protocol) is used to transmit the binding information notification.

  In S124, when the remote control terminal 30 receives the binding information notification transmitted from the karaoke apparatus 20, the remote control terminal 30 stores the IP address included therein as the IP address of the binding partner, and indicates that the binding has been established. The completion notification is bundled and transmitted to the karaoke device 20 of the partner. For example, TCP (Transmission Control Protocol) is used to transmit the binding completion notification.

  By the above-described series of processing, the karaoke device 20 and the remote control terminal 30 recognize each other's IP address, and the binding is established. Thereafter, the bundled karaoke device 20 and the remote control terminal 30 communicate with each other based on their IP addresses, so that the operation on the karaoke device 20 can be performed from the bundled remote control terminal 30. .

[effect]
The karaoke system of the embodiment has the following effects.
The DHCP router 10 can dynamically assign the IP address of the remote control terminal 30 according to the subnet corresponding to the IP address of the karaoke apparatus 20 associated with the remote control terminal 30. In this way, in a network environment in which a plurality of subnets are constructed for each model of the karaoke apparatus 20, it is not necessary for the remote control terminal 30 to have a plurality of unique IP addresses respectively corresponding to the plurality of subnets. Address can be used efficiently. In addition, since an IP address can be dynamically assigned to the remote control terminal 30, the remote control terminal 30 is moved to another network and used by being tied to the karaoke device 20 and the remote control terminal 30 connected to the network. Is easy.

  The DHCP router 10 notifies the IP address assigned to the remote control terminal 30 to the karaoke device 20 of the binding partner. Thereby, the karaoke apparatus 20 can tie up its own IP address to the remote control terminal 30 of the other party, based on the IP address notified from the DHCP router 10. By doing in this way, each of the karaoke apparatus 20 and the remote control terminal 30 to be bundled can grasp the IP address of the communication partner. In this way, for example, it is not necessary to broadcast communication data with its own IP address in the network for the purpose of notifying the communication partner whose IP address is unknown, thus reducing the communication load. it can.
