Description

How to pair your remotes {Method for paring in remote controllers}

The present invention relates to a pairing method and a control device, and more particularly, to a pairing method between a device and a control device in a home network and a control device therefor.

To date, remote controls have been used to control devices in the home network. However, as the number of devices connected in a home network increases with the recent development of video and audio media, it has been inconvenient in that a remote controller corresponding to the device must be operated separately in order to operate a plurality of devices.

Recently, instead of using a plurality of remote controllers, it is possible to operate the devices in the home network using a remote control that can operate a plurality of devices. Generally, such a remote control is called an integrated remote control.

Since the integrated remote controller can communicate in one direction only, in order to operate a plurality of devices, an IR code for each device must be registered before use. However, in order to register the IR code on the integrated remote controller, the user must know the IR code for each device, and even if it is known, there is an inconvenience in that a plurality of manual operations must be performed to register it. In addition, during the registration of the IR code, it was not easy to check whether the IR code entered by the user was certain.

In particular, as the number of media playback devices connected in a home network increases as the video and audio media develops, in order to register a plurality of devices with a remote controller, the above-described manual operation must be repeatedly performed as many as the number of devices to be registered. Discomfort was aggravated further. In addition, when paired with a remote controller used in an up / down next door in an adjacent household, such as an apartment, there is a problem that crosstalk is caused by processing a signal of a device in use.

An object of the present invention is to provide a method for pairing a device and a control device in a home network and a control device therefor.

Pairing method according to an embodiment of the present invention comprises the steps of receiving a remote control unit connected to the host to receive a signal; Entering a pairing mode by the remote control receiver for a predetermined time; Entering the pairing mode by the remote controller; Pairing the remote controller with the remote controller; And terminating the pairing of the remote controller receiver and the remote controller.

According to the present invention, the information of the controllable device in the home network is displayed to the user, and the user can pair with the device to be connected by selecting the displayed device through the information of the displayed device. Is improved.

In addition, since the receiver and the transmitter are matched one-to-one, it is possible to prevent the crosstalk from being caused by the signal of the other receiver.

2 to 3 are views for explaining an embodiment when the control device according to an embodiment of the invention is implemented in the form of a remote control having a plurality of keys.
4 is a flow chart illustrating a pairing method according to an embodiment of the invention.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is a block diagram showing the configuration of a control device according to an embodiment of the present invention. According to FIG. 1, the control device 100 includes a searcher 110, a user interface 120, and a controller 130. The control device 100 may be implemented as a digital TV, a remote controller, or the like. The control device 100 may bidirectionally communicate with a plurality of devices in a home network and control each device. Here, the bidirectional communication may include all existing communication technologies such as BT, RF (ZigBee, Bluetooth, etc.), Wi-fi, HDMI-CEC, Wireless HDMI-CEC, and all future bidirectional communication technologies.

The search unit 110 may receive a profile from devices in the home network and search for a controllable device. In detail, the search unit 110 may broadcast a profile request signal to search for controllable devices in the home network, and receive a profile from each device in response to the request signal, thereby providing a current home network. It is possible to grasp a plurality of controllable devices in the apparatus.

Here, a plurality of devices may be various types of devices that can be connected to each device in a home network such as TV, STB, HTS (home theater), BDP (Blue-ray disc player), DVDP, HDDR, PMP, and DSC. Can be. Here, BDP refers to a Blu-ray high density optical disc player capable of recording a large capacity of several tens of Gbytes or more. In addition, the profile may include an identification ID for the corresponding device, a manufacturer of each device, a function, and the like.

Meanwhile, the search unit 110 may be implemented in a form of searching for a controllable device in the home network when a pairing command of the user is applied. In addition, the search unit 110 may be implemented in a form of periodically searching for a controllable device in the home network. In detail, the controller may periodically search for a controllable device in the home network and perform a following operation when a new device other than the previously registered device is found.

The user interface 120 may display information about the found device. In detail, the user interface 120 classifies the device searched through the searcher 110 based on the profile received through the searcher 110, according to the manufacturer or the device type to assign the device type and the manufacturer. Information such as the index number can be displayed to the user.

For example, the user interface 120 may be implemented as a device in which an input and an output are simultaneously implemented, such as a touch pad, to display manufacturer information, device information, and the like for the found device.

In addition, the user interface 120 may include a plurality of keys, and map the searched device to each of the plurality of keys, and display the information on the searched device by providing a backlight for the mapped key. have. Specifically, the user interface unit 120 includes a plurality of keys that can provide a backlight for the user to set or select various functions for controlling the devices in the home network, and map the searched device to each of the plurality of keys. Alternatively, the searched devices may be mapped to a plurality of keys for each device type, and the searched device information may be provided by providing a backlight with respect to the mapped keys to display searched device information about the number of searched devices and the type of searched devices. For example, when three devices of TV, DVD, and HTS are searched through the search unit 110 in the home network, the user interface unit 120 is set to 1, TV is 2, and HTS 3 is set for each device. An index can be assigned, and 1, 2, and 3 numeric keys can provide a backlight to indicate that three devices have been found.

Meanwhile, the user interface unit 120 may determine whether there is a registered device among the searched devices, and display the device except for the registered device. The searched device does not go through such a determination process. It may be implemented in a form that displays all. Such an operation may be performed by the user interface 120 or may be performed by the searcher 110.

On the other hand, the user interface 120 may be provided with a button provided to be used only for the operation for receiving a pairing command of the user. In addition, the user interface 120 may determine that a pairing command of the user is applied when a button provided in the conventional remote controller or the digital TV is pressed in a specific manner. For example, when a user presses a mode change button after pressing a specific function button, when the existing mode change button is pressed in multiple times in a short time, or when the existing mode change button is pressed for a predetermined time or more. In this case, it may be determined that the user is a pairing command. In addition, the pairing command may be input in various formats.

When one of the displayed devices is selected, the controller 130 may register the selected device as a controllable device. In detail, when the user selects one of the devices displayed through the user interface unit 120, a task is generated based on a profile of the corresponding device, and various control commands corresponding to the generated task are in the form of a task list. You can register. Accordingly, when the user later operates the device, a control command may be sent to the device using the registered task list to perform a task.

Here, the task may include watching TV, viewing recorded TV, watching recorded TV, playing a disc, listening to radio, listening to music, viewing photos and videos, and powering on / off all devices. These tasks may be preset, or may be generated based on a corresponding profile collected from a plurality of devices in the home network. In addition, such a task may be generated by being limited to a corresponding device or may be generated in combination with previously registered devices. For example, when the devices connected to the home network are TV, DVDP, or HTS, the controller 130 may generate a task list such as TV view, DVD view, and the like.

In addition, the controller 130 may transmit a control code for providing feedback to the paired device. In detail, the controller 130 may be implemented such that the device selected by the user performs a certain operation in response to the user's device selection. For example, the selected device displays the key name of the mapped key, displays the message indicating the pairing completion state, selects the channel corresponding to the key name of the mapped key, selects a predetermined sound The control code may be transmitted to the device to perform an operation such as an operation of outputting the.

After the feedback of the device selected by the user is provided, the controller 130 may be implemented to be paired with the selected device when a user's confirmation command is input or a predetermined time elapses. Accordingly, in response to the user's selection, the control device 100 provides feedback on the device currently selected by the user, thereby improving user convenience.

2 to 3 are diagrams for describing an exemplary embodiment when the control device is implemented in the form of a remote controller having a plurality of keys.

Referring to FIG. 2, the control device 100 according to FIG. 1 is implemented in the form of a remote controller 200 having a plurality of keys, and the control device 100 of the present application is separately used only for an operation for performing a pairing command. The pairing button 210 and a function key 220 for selecting a user and displaying information of the corresponding device during the pairing operation are provided. In detail, the pairing button 210 is used to receive a pairing command of the user, and the function key 220 is used to display information such as the number of searched devices and the type of searched devices, or to be selected by the user.

According to FIG. 3, the control device 100 according to FIG. 1 is implemented in the form of a remote controller 300 and includes three TVs 10, 20, and 30 capable of two-way communication in a home network. Currently, there are three devices that can be paired in the home network, and the remote control 300 includes a TV change key 311 and numeric keys 320 for 1, 2, and 3 numbers to provide a backlight. Accordingly, the user may know that three TVs have been detected and may pair with the corresponding device by selecting one of the displayed numeric keys 320.

In this case, the remote controller 300 corresponds to the user's numeric key selection, the corresponding device displays a specific feedback, for example, the key name of the mapped key, or the selected device corresponds to the key name of the mapped key The control code may be transmitted such that an operation for performing the operation of selecting a channel is implemented. Accordingly, the user can check whether the device selected by the user is the device to be paired with.

Meanwhile, the remote controller 300 transmits a control code for displaying a key name of a key mapped to a device before each user selection or for displaying a channel corresponding to a key name of a mapped key. The information displayed on the device may be used to allow the user to identify and select a device to be selected by the user.

A pairing process of the remote controller receivers 11, 12, 13 and the remote controller 300 connected to the TVs 10, 20, 30 according to the related art, for example, is as follows.

When the user presses a receiving button of the remote control receivers 11, 12 and 13, the remote control receivers 11, 12 and 13 enter a pairing mode. If there is no response for a certain period of time, the pairing mode is terminated. Next, when the user presses the pairing button 210 of the remote control 300, the remote control 300 enters the pairing mode. If there is no response for a certain period of time, the pairing mode is terminated.

Next, when a user's confirmation command is input or a preset time elapses, pairing with the selected device is completed and the TVs 10, 20, and 30 are operated by the remote controller 300.

The steps of connecting the remote controller receivers 11, 12, 13 to the host (S410) and applying a pairing command by the user (S430) may be reversed.

For example, when the present application is implemented in a remote control having a plurality of keys, the searched device is mapped to each of the plurality of keys, and the searched device displays information about the searched device by providing a backlight for the mapped key. can do. In addition, when the present application is implemented in a remote control having a touch screen, information about the found device may be displayed on the touch screen.

When the operation of the TVs 10, 20, and 30 is finished and pairing is necessary again, the remote controller receivers 11, 12, and 13 may be disconnected from the host and then connected again to perform the above process.

For the paired TVs 10, 20, 30, a task list for the executable task may be generated based on the received profile. In detail, when the user selects one of the displayed devices, the user may perform a task, a control code for implementing the task, and a key mapping corresponding to the control code in the form of a task list. . Accordingly, the user may perform the pairing operation only by selecting the information of the displayed device, thereby improving user convenience.

According to an embodiment of the present invention, a separate button for entering the pairing mode is not required for the remote controller receivers 11, 12, and 13, and the user can be paired at a desired moment, thereby preventing crosstalk with other devices.
