Description

  The present invention relates to a remote control system that receives remote control signals transmitted from a plurality of wireless remote control terminals and processes them substantially simultaneously.

  If a single computer can be remotely operated by a plurality of users at the same time using a remote control terminal, a plurality of users can simultaneously use one or a plurality of applications running on the computer. For example, when a car racing game program is executed on a computer connected to a large screen monitor, a wireless remote control terminal is assigned to each of a plurality of racing vehicles, and each user uses a wireless remote control terminal to play a racing vehicle. Can be operated freely, it is possible to develop a game full of realism by competing with many users.

  At this time, if a wireless remote control terminal is used, each user can perform an operation at a position away from the computer, so that simultaneous operation by a large number of users is facilitated. However, the conventional infrared remote control that is widely used for remote controls for mobile phones and home appliances is not suitable for a plurality of simultaneous use because pulse signals transmitted from each remote control interfere with each other. On the other hand, a radio remote controller can be used simultaneously, but since the penetration rate is low, a dedicated remote controller must be prepared separately.

  On the other hand, Bluetooth has spread as a short-range wireless communication system, and Bluetooth has been implemented in many mobile phones. Therefore, if the wireless remote control is a Bluetooth system, many users can use their own mobile phone as a remote control terminal.

  In Patent Document 1, a playback device transmits resume information to a remote control device side using a Bluetooth serial port profile (SPP), and the remote control device transmits the resume information to the playback device at the next playback. A technique is disclosed that makes it unnecessary to manage resume information for each user in a playback device by jumping and playing back.

  In Patent Document 2, when a wristwatch type terminal device transmits a camera shutter pressing command to a mobile phone device using a Bluetooth hands-free profile (HSF), the camera of the mobile phone device executes imaging, and after imaging is completed. When the wristwatch terminal device requests the mobile phone device to acquire a captured image, the mobile phone device uses the Bluetooth image profile (BIP) to transfer image data to the wristwatch terminal and display it on the screen of the wristwatch terminal. Technology is disclosed.

  In Patent Document 3, the information terminal controls the imaging operation of the imaging terminal using a Bluetooth serial port profile (SPP), and before the imaging terminal transfers image information with a large amount of data to the information terminal, the captured image The related information is automatically transferred to the information terminal, and when the information terminal requests the imaging terminal to acquire a captured image after the imaging is completed, the imaging terminal can acquire the Bluetooth image profile (BIP) or the Bluetooth object exchange profile (OPP). A technique is disclosed in which captured image data is transferred to an information terminal using an image and displayed on the screen of the information terminal.

  In Patent Document 4, when the video display device stores in advance a remote control transmission code of a plurality of remote controllers and a divided screen area in association with each other and receives the remote control transmission code together with the key operation key code from each remote control device, the screen is displayed. A technique is disclosed in which a user divides a plurality of screens and assigns a divided screen area to each user as an operation target.

  Patent Document 5 discloses a television receiver system capable of bidirectional communication and a plurality of IP remote controllers. In this system, a wireless LAN is used for communication, and control commands and image data are transmitted and received between the IP remote controller and the operation target device via bidirectional communication via the IP network.

  In Patent Document 1, one-to-one pairing can be realized between the remote control device and the playback device, but the playback device cannot be controlled simultaneously from a plurality of remote control devices. In this method, Bluetooth SPP is used, and resume information can be transmitted and received bidirectionally between the remote control device and the playback device. However, since the amount of data transmitted once by SPP is limited to 1024 bytes, the capacity is large. Not suitable for data transfer.

  In Patent Document 2, one-to-one pairing can be realized between a wristwatch-type terminal device and a camera-equipped mobile phone device, but a camera-equipped mobile phone device cannot be controlled simultaneously from a plurality of wristwatch-type terminal devices. . In addition, it is necessary to disconnect the control HFP session before transferring image data from the mobile phone device to the wristwatch type terminal device by BIP, and a control command from the wristwatch type terminal device cannot be accepted at the time of transfer.

  In Patent Literature 3, an information terminal transmits a control command to an imaging terminal and can simultaneously receive related information of a captured image from the imaging terminal by SPP. However, as in the case of Patent Document 2, the imaging terminals cannot be controlled simultaneously from a plurality of information terminals. Further, since SPP, BIP, and OPP cannot be used together, as in the case of Patent Document 2, there still remains a technical problem that a control command from an information terminal cannot be received when captured image data is transferred.

  In Patent Document 4, the screen area of the video display device is divided for each of a plurality of remote controllers so that a plurality of users (viewers) can share the video display device at the same time. Since it has to be used, the circuit and the control mechanism are complicated, and as a result, there is a problem that the remote controller and the receiver are large and expensive. In addition, bidirectional communication was not possible with this method.

  In Patent Document 5, since communication is performed by a wireless LAN, bidirectional communication can be easily realized. However, since the communication module for wireless LAN consumes a large amount of power, it is not suitable for mobile terminals that are premised on battery driving. In addition, in a wireless LAN, since a plurality of wireless terminals share a band, the communication speed decreases when the plurality of wireless terminals concentrate on one access point.

  An object of the present invention is to solve the above-described problems of the prior art and provide a remote control system capable of controlling a control device to be operated from a plurality of remote control terminals substantially simultaneously by bidirectional communication.

Each mobile phone 3 interprets the received feedback command and switches the display on the terminal display or outputs force feedback.

  FIG. 3 is a functional block diagram showing the configuration of the main part of the computer 1 and each mobile phone 3.

  In Bluetooth, one of the devices that communicate with each other is a master and the other is a slave. According to Bluetooth specifications, up to seven slaves can be connected to one master, and any device can be a master and a slave. However, the device that first requests connection is the master, and the device that responds to this connection request is the slave. In the present embodiment, since various request messages are transmitted to the computer 1 when the mobile phone 3 is operated, the mobile phone 3 becomes a master and the computer 1 becomes a slave.

  For this reason, in the present embodiment, the number of remote control terminals that can accept each Bluetooth dongle mounted on the computer 1 is limited to “1”. Therefore, the computer 1 has a function corresponding to the number of mobile phones 3 to be functioned as remote control terminals. A guest computer 13 capable of mounting a number of Bluetooth dongles is virtually mounted, and one or a plurality of Bluetooth stacks are installed for each guest computer 13 to operate each Bluetooth dongle. In FIG. 3, a Bluetooth dongle mounted on the guest computer 13 and the mobile phone 3 is represented by a pair of an SPP transmission module 116 (303) and an SPP reception module 117 (304).

In the Value (0) field, information indicating that the message is a registration response is described, and in the Value (1) field, the string is displayed. In the attached information storage unit 106, an identification ID “1” for specifying the Bluetooth dongle is described. In the Value (2) field, a list of application IDs of applications executable on the host computer 11 is described.

  The IP communication management unit 101 converts the registration response into an IP packet at time T8 and sends it back to the guest computer 13 via the virtual IP network. In the guest computer 13, the IP packet received by the IP reception module 112 is restored to a registration response in the IP communication management unit 113, and transferred to the main control unit 114 at time T9. The main control unit 114 converts the registration response into an SPP packet at time T10, and returns this to the mobile phone 3 from the SPP communication management unit 115 via the SPP transmission module 116.

  Upon receiving this registration response message, the mobile phone 3 extracts the identification ID and registers it in the identification ID storage unit 305, further extracts the application ID and registers it in the application ID storage unit 309, and performs a series of initial registration procedures. Complete.

  When canceling registration, a message requesting cancellation of pairing registration is transmitted from the mobile phone 3 to the guest computer 13. The format of this deregistration request message is the same as that of the registration request message described with reference to FIG. 7, but the deregistration Flag (0xFE) is described in the Value (0) field, and the Value (1) field contains Indicates the MAC address of the Bluetooth dongle to be released, and the user terminal ID is described in the Value (2) field.

  When the guest computer 13 receives this deregistration request message, the guest computer 13 notifies this to the association information storage unit 106 of the host computer 11. In response to this notification, the association information storage unit 106 selects the Bluetooth dongle corresponding to the registered contents of the Value (1) field and Value (2) field, and clears the user terminal ID.

  Next, an embodiment in which the terminal user operates his / her mobile terminal 3 to operate the application of the host computer 1 will be described in detail along the sequence flow of FIG. 10.

  In the mobile phone 3, when a Bluetooth dongle and an application are selected by the terminal user and an input event such as a key operation is detected, this is notified to the main control unit 301 as an operation request. The main control unit 301 acquires the identification ID of the Bluetooth dongle from the identification ID storage unit 305, further acquires the application ID from the application ID storage unit 309, and describes the operation code corresponding to the identification ID, application ID, and key operation. The generated operation request message is generated and transferred to the SPP communication management unit 302.
