As shown in FIG. 1, a display device 200, other external devices 400a to 400e, and the display device 200 and external devices in a predetermined space (eg, hotel room Room 1) There is a remote controller 500 for controlling (400a ~ 400e). For example, the remote controller 500 may be a mobile terminal such as a mobile phone of a guest staying in a hotel room (Room 1).

The display device 200 may be an analog TV having a display unit, a digital TV, a smart TV, a computer monitor, and the like, and is a device equipped with an interface to which the master scheduler 100 can be connected, as described later.

The external devices 400a to 400e refer to electronic devices other than the display device 200, and generally have an interface capable of connecting the sub-scheduler 300 as described below. In some cases, an electronic device without an interface may exist, such as the external device 400e.

The display device 200 and the external devices 400a to 400e may support different wireless communication protocols. Depending on the embodiment, both the display device 200 and the external devices 400a to 400e may support different wireless communication protocols, and some of the display device 200 and the external devices 400a to 400e may be different from each other. It may also support wireless communication protocols.

In FIG. 1, as an example, a first external device 400a is a device supporting WLAN (Wireless LAN) (Wi-Fi), a second external device 400b is a device supporting Bluetooth, and a third The external device 400c is a device supporting UWB (Ultra Wideband), the fourth external device 400d is a device supporting ZigBee, and the fifth external device 400e is a device supporting infrared communication (IrDA, infrared Data Association). It is assumed that it is a supported device. However, FIG. 1 is only an example, and external devices 400a to 400e may support other wireless Internet protocols or short-range communication protocols in addition to the above communication protocols. In addition, it is assumed that the fifth external device 400e does not have an external memory or an interface for connecting other external devices.

The master scheduler 100 and the sub scheduler 300 are designed to enable communication according to a first communication protocol. In the present embodiment, the description is made on the assumption that the master scheduler 100 and the sub scheduler 300 are designed to enable communication according to Wi-Fi or Wi-Fi direct, but the present invention is not limited thereto.

The master scheduler 100 is connected to the display device 200 having a display unit, and the sub scheduler 300 is connected to an external device that does not support the first communication protocol. Referring to FIG. 1, the sub scheduler 300 is connected to the second external device 400b to the fourth external device 400d, respectively. Accordingly, the second external device 400b to the fourth external device 400d correspond to devices that do not support the first communication protocol, and the first external device 400a supporting the first communication protocol has a sub-scheduler. 300 is not connected.

In FIG. 1, as an example, the master scheduler 100 and the sub scheduler 300 are respectively connected to the display device 200 and the external devices 400b to 400d through a USB interface, but are not limited thereto.

Since each of the master scheduler 100 and the sub scheduler 300 operates in a state connected to the device, the master scheduler 100 and the sub scheduler 300 are respectively connected to the display device 200 and the external device 400. Explain assuming.

When a user wants to control various external devices 400 using the remote controller 500, a procedure for pairing the remote controller 500 and the external device 400 must be preceded. Of course, when the remote controller 500 and the display device 200 are paired, the display device 200 may be controlled using the remote controller 500. In this case, the user must know the PIN code corresponding to each of the external devices 400. According to an embodiment of the present invention, the PIN code corresponding to each of the external devices 400 is transmitted from the master scheduler 100 connected to the display device 200 to the sub scheduler 300 connected to the external device 400 Can be. Transmission of the PIN code from the master scheduler 100 to the sub scheduler 300 also assumes that the pairing procedure for communication connection between the master scheduler 100 and the sub scheduler 300 is completed. In some cases, the master scheduler 100 may disconnect the pairing connection between the remote controller 500 and the external device 400 by changing a PIN code corresponding to the external device 400.

As described above, according to the operation of the master scheduler 100, the wireless network connection between the remote controller 500 and the external device 400 can be controlled/scheduled, so it is called a master scheduler, and the sub scheduler 300 is the master scheduler 100 ), so it is called a sub-scheduler. However, the present invention is not limited only to these names.

Depending on the embodiment, the master scheduler 200 may know in advance the MAC addresses of each of the plurality of sub-schedulers 300 existing in a predetermined space. Accordingly, the master scheduler 200 may allow communication according to the first communication protocol only with the sub scheduler 300 corresponding to a known MAC address. For example, a guest (user) staying in a hotel's room (Room 1) only needs to control the devices existing in his room, but does not need to control devices existing in other rooms, and should not allow this from a security perspective. . Accordingly, the master scheduler 200 may only allow communication with the sub scheduler 300 corresponding to a pre-stored MAC address.

FIG. 2 is a block diagram showing configuration modules of a master scheduler and a sub scheduler according to an embodiment of the present invention, and FIG. 3 is a method for connecting communication between a master scheduler and a sub scheduler according to an embodiment of the present invention. It is a flowchart showing an example. The operations of the master scheduler 100 and the sub scheduler 300 will be described with reference to FIGS. 2 and 3 as follows.

In addition, it is assumed that the display device 200 to which the master scheduler 100 is connected is turned on, and the external device 400 to which the sub scheduler 300 is connected is turned on.

2, the master scheduler 100 includes a memory 110, a wireless communication module 120, and an interface unit 130, and the sub scheduler 300 includes a memory 310, a wireless communication module ( 320) and an interface unit 130.

The master scheduler 100 is connected to the display device 200 through the interface unit 130, and the sub scheduler 300 is connected to the external device 400 through the interface unit 330.

The interface unit 130 and the interface unit 330 are, for example, a USB terminal, a CVBS (Composite Video Banking Sync) terminal, a component terminal, an S-video terminal (analog), a DVI (Digital Visual Interface) terminal, an HDMI (High Definition Multimedia Interface) terminal, RGB terminal, D-SUB terminal, etc. However, in this embodiment, a USB terminal will be described as an example.

The wireless communication module 120 of the master scheduler 100 and the wireless communication module 320 of the sub scheduler 300 may communicate according to a first communication protocol. The wireless communication module 120 and the wireless communication module 320 are, for example, WLAN (Wireless LAN) (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet). Access), Bluetooth, etc. may be supported, but in this embodiment, a case of supporting the Wi-Fi protocol will be described as an example.

In addition, the memory 310 of the sub scheduler 300 may store various programs required for the operation of the sub scheduler 300 and a communication protocol required for communication with the external device 400 connected to the sub scheduler 300. have.

In order to describe the operation of the master scheduler 100 and the sub scheduler 300, a pairing procedure for communication connection between the master scheduler 100 and each of the sub schedulers 300 must be preceded. This will be described with reference to FIGS. 2 and 3.

The sub scheduler 300 receives information on the external device 400 from the external device 400 (S601). The interface unit 330 of the sub scheduler 300 may receive information on the external device 400 through an interface (eg, a USB port) provided in the external device 400. The information on the external device 400 may include information on a communication protocol supported by the external device 400 and information on a type of the external device 400. Depending on the embodiment, a separate protocol for communication between the sub scheduler 300 and the external device 400 may be required. In this case, a program for the separate protocol is the sub scheduler 300 and/or an external device ( 400) It may be pre-stored in each memory.

The wireless communication module 320 of the sub scheduler 300 broadcasts a first signal including information on the received external device 400 (S602). As an example, the first signal may be in the form of a beacon signal packet, but is not limited thereto. The first signal may include address information (eg, MAC address) of the sub scheduler 300.

The wireless communication module 120 of the master scheduler 100 receives the first signal (S603).

According to an embodiment, when the address information of the sub scheduler 300 is included in the first signal, the master scheduler 100 checks the address information of the sub scheduler 300 included in the first signal (S604). ). Address information for a plurality of sub-schedulers 300 may be stored in advance in the memory 110 of the master scheduler 100. For example, for each master scheduler 100 located in a room, a hotel manager may store address information of the sub-schedulers 300 located in the same room as the room in which the master scheduler 100 is located in a memory in advance. I can. Accordingly, the master scheduler 100 checks whether the address information of the sub scheduler 300 included in the first signal matches any one of the address information stored in its memory 110, and Communication connection between the master scheduler 100 and the sub scheduler 300 may be allowed only when it matches any one of the address information stored in 110.

The interface unit 130 of the master scheduler 100 transmits the information included in the received first signal to the display device 200. The interface unit 130 of the master scheduler 100 may transmit some or all of the information included in the received first signal to the display device 200.

The display device 200 may display a message including information included in the first signal through the display unit (S606). The message may include information on the type of the external device 400 to which the sub scheduler 300 is connected and/or information on a communication protocol supported by the external device 400 to which the sub scheduler 300 is connected. . For example, the information on the type of the external device 400 relates to classification according to the function of the external device 400, and may be information on whether the external device 400 is a lighting, an STB, or a refrigerator. It may be specific information such as a model name of the device 400 or a serial number (S/N).

In addition, the message may include content notifying that the sub scheduler 300 connected to the external device 400 can attempt to pair with the master scheduler 100 connected to the display device 200.

When the user confirms a pairing attempt between the master scheduler 100 and the sub scheduler 300 through a message displayed on the display unit of the display device 200, the display device 200 sends a signal corresponding to the user confirmation to the master scheduler. It transmits to (100) (S607).

The wireless communication module 120 of the master scheduler 100 transmits a pairing request signal to the sub scheduler 300 (S608).

The wireless communication module 320 of the sub scheduler 300 receives the pairing request signal and transmits a response signal for accepting pairing to the master scheduler 100 in response thereto (S609).

When the wireless communication module 120 of the master scheduler 100 receives the response signal, the pairing procedure between the master scheduler 100 and the sub scheduler 300 is completed. After that, data may be transmitted/received between the master scheduler 100 and the sub scheduler 300 according to the first communication protocol.

When the initial pairing procedure between the master scheduler 100 and the sub scheduler 300 is completed according to the above procedure, after that, when connecting the master scheduler 100 and the sub scheduler 300 to each device or At startup, the pairing procedure can be automatically performed without user intervention.

Meanwhile, the master scheduler 100 may directly communicate with the first external device 400a supporting the first communication protocol without the sub scheduler 300. In this case, the master scheduler 100 performs a pairing procedure with the first external device 400a.

5 is a flowchart illustrating an example of a method for a master scheduler to control a communication connection between an external device and a remote controller according to an embodiment of the present invention. In FIG. 5, the spatial environment illustrated in FIG. 1 is described as an example, and description is made on the assumption that the pairing procedure between the master scheduler 100 and each sub-scheduler 300 is completed.

According to an embodiment of the present invention, in order for the master scheduler 100 to control the communication connection between the external device 400 and the remote controller 500, the master scheduler 100 may generate a PIN code for each external device 400. The generated PIN code may be generated and transmitted to the sub scheduler 300 connected to the corresponding external device 400.

The master scheduler 100 connected to the display device 200 uses the information included in the first signal transmitted from the sub scheduler 300 in the pairing process described above with respect to FIG. 3 to generate a PIN code corresponding to the information. Generate (S701). Specifically, the master scheduler 100, as information included in the first signal transmitted from the sub-scheduler 300, information on a communication protocol supported by the external device 400 or/and the type of the external device 400 A PIN code corresponding to the external device 400 may be generated by using the information about.

The master scheduler 100 may map the generated PIN code to information on the external device 400 and store it in the memory 110.

The wireless communication module 120 of the master scheduler 100 transmits the second signal including the generated PIN code to the sub scheduler 300 (S702).

The wireless communication module 320 of the sub scheduler 300 receives the second signal (S703).

The interface unit 330 of the sub-scheduler 300 transmits the received PIN code in the second signal to the external device 400 connected thereto (S704). The sub-scheduler 300 may transmit the second signal to the external device 400 as it is, or may extract the PIN code included in the second signal and transmit it to the external device 400.

The external device 400 generates a third signal including the PIN code and broadcasts it (S705). For example, when the user wants to control the second external device 400b using the remote controller 500, a pairing procedure for communication connection between the remote controller 500 and the second external device 400b must be preceded. do. In this case, pairing may be completed only when the user knows the PIN code for the second external device 400b. According to an embodiment of the present invention, the PIN code for the second external device 400b is transmitted from the master scheduler 100 to the sub scheduler 300a, and the second external device 400b is transmitted to the sub scheduler 300a. You can receive your own PIN code from ). Accordingly, when the second external device 400b broadcasts a beacon signal required for its own discovery, the PIN code may be included in the beacon signal and broadcast.

Meanwhile, the interface unit 130 of the master scheduler 100 transmits the generated PIN code and the information included in the first signal to the display device 200 connected thereto (S706). Step S706 may be performed together with step S703, or may be performed before or after step S703.

The display device 200 receives the PIN code and information on the external device 400 from the master scheduler 100 through the external device interface unit 220, and the control unit 240 of the display device 200, The display unit 250 may be controlled to output a message including the PIN code and information on the external device 400 (S707). The message is for each of the external devices 400 received from the sub scheduler 300 connected to the external devices 400 existing in a predetermined space by the master scheduler 100 connected to the display device 200. Information (eg, the name and type of the external device 400 and/or the name of a communication protocol supported by the external device 400) and a PIN code mapped thereto may be included.

The user may check the PIN code of the external device 400 to be paired with the remote controller 500 through the message output on the display unit 250 of the display device 20.

In some cases, since the master scheduler 100 may directly communicate with the first external device 400a supporting the first communication protocol without the sub-scheduler 300, the master scheduler 100 may provide a first external device ( The PIN code generated in response to 400a) may be directly transmitted to the first external device 400a.

In addition, in the case of an external device that does not have an interface unit to which the sub-scheduler 300 can be connected, such as the fifth external device 400e shown in FIG. 1, the master scheduler 100 is connected to the fifth external device 400e. Do not dynamically generate a PIN code for. In this case, the fixed PIN code for the fifth external device 400e is stored in advance in the memory 230 of the display device 200, and the PIN code for the fifth external device 400e is stored in the display device upon user request. It may be output through the display unit 250 of 200.

Meanwhile, the master scheduler 100 may periodically or aperiodically change the PIN code for each of the external devices 400. For example, in the case of a hotel, when user 1 stays in the room 1 and then leaves the room and then another user 2 stays in the room 1, from the perspective of the hotel manager, the mobile terminal 500 held by user 1 ) It is necessary to disconnect the communication connection between the devices in the room (Room 1). In this case, when the PIN code for each external device 400 is changed in the master scheduler 100, the communication connection between the mobile terminal 500 held by User 1 and the devices in the room 1 may be terminated. .

In addition, according to an embodiment, a specific device among several devices existing in the room 1 may be a euro device that can be used only after a user pays a fee.
