Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, in particular to a method and system for independently controlling multiple televisions with a single remote controller. Background Art

[0002] There is a big disadvantage of remote control in TV malls and TV batch testing. There are many TVs, and the accuracy of one remote control to control one TV through infrared is low, and it is easy to control the TV next to it. Currently, the above problem is solved by one-to-one remote control through the Bluetooth of the remote control. At this time, two problems will arise: one is that the Bluetooth remote control is easy to pair with other TVs, because nearby TVs are within the pairing distance; the other problem is that if you need to control other TVs at this time, you need to unpair the Bluetooth of the TV and pair the target TV again, which will cause the remote control to be inaccurate for multiple TVs placed nearby. Summary of the invention

[0003] In order to solve the technical problem in the prior art that the remote control is prone to inaccurate control such as channel switching when controlling multiple televisions, the purpose of the present invention is to provide a method and system for independently controlling multiple televisions with a single remote control. By combining Bluetooth and infrared, in the scenario of controlling multiple televisions, the remote control can accurately control one of the televisions point to point, and can quickly switch the television to be controlled, thereby improving convenience and testing efficiency.

[0004] The present invention solves the above problems through the following technical solutions:

[0006] S100. The remote control is paired with all target TVs in turn via Bluetooth, and the binding information with all target TVs is stored and maintained;

[0007] S200. The remote control is aimed at the target TV and any button of the remote control is pressed. The target TV receives the infrared signal, analyzes the infrared signal, and sends a broadcast to the Bluetooth application. The TV and the remote control establish a Bluetooth connection and determine whether the TV needs to be switched. If so, enter S300, otherwise enter S400;

[0008] S300. When you need to switch TV, you only need to point the remote control toward the next target TV you want to switch to and press any button on the remote control. The current target TV sends a connection request to the remote control, and the remote control compares the MAC address to establish a Bluetooth connection between the target TV and the remote control, and enter S400;

[0012] S102. The remote controller writes information of the target TV to achieve binding.

[0013] As a further improvement, in S100, the remote controller writes the information of the target TV by calling the write function of the flash storage API interface.

[0014] As a further improvement, it is determined that the remote controller is aimed at the target TV and any button of the remote controller is pressed, which is achieved by:

[0015] In the keycode.xml file of the target TV, the key values ​​of the infrared buttons are defined so that when the target TV receives any infrared button, it will add additional keycode value information to the infrared signal, and assign the additional keycode value to the Bluetooth application in the target TV for processing, and set a broadcast receiver in the Bluetooth application to monitor whether the remote control button is pressed by the remote control facing the target TV.

[0016] As a further improvement, in S200, when the remote control is aimed at the target TV and any button of the remote control is pressed, the target TV broadcast receiver receives the infrared signal broadcast, calls the BluetoothAdapter.getBondedDevices interface, reads the device array of the bound devices of the target TV, and then calls the BluetoothManager.getConnectDevices(BluetoothProfile.GATT) interface to read the connection status of the bound devices respectively.

[0017] As a further improvement, the S200 further includes:

[0018] When the target TV currently has no connected device, the device.connectGatt(this,false,gattCallback) interface is called in sequence on the device array to connect the remote control.

[0030] The following will be combined Figure 1-2 , a method and system for independently controlling multiple televisions with a single remote controller according to an embodiment of the present application are described in detail. It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0031] Example 1

[0032] Combined with Figure 1-2 As shown, a method for a single remote control to independently control multiple TVs is shown. By combining infrared and Bluetooth remote control, the remote control can be paired with multiple TV devices through Bluetooth. The controller in the remote control parses the Bluetooth broadcast packet sent by the TV, temporarily stores the Bluetooth MAC address and pairing key in a custom structure, and then stores the data structure information in the storage of the Bluetooth remote control. After all TVs are bound by the remote control, the remote control is used to remotely control the TV to be controlled through infrared. When the TV decodes the infrared signal, the Bluetooth interface of the TV is called to initiate a Bluetooth connection request to the remote control to achieve precise control. When switching to remote control of the TV, aim at other TVs and press the remote control button. Repeat the above operation, and the remote control performs the unpairing and pairing actions.

[0033] The following describes in detail the method of independently controlling multiple TVs with a single remote controller of the present invention in conjunction with examples implemented on multiple Android TVs;

[0034] First, in a multi-TV environment, there are three TVs, and they are all placed in front but not overlapping. The specifications of the remote control require the use of an nRF52 microcontroller and built-in flash storage, and the infrared function of the remote control must remain available in the Bluetooth remote control state, which can be achieved by upgrading the firmware.

[0035] The specific steps include:

[0036] S100. The remote control is paired with all target TVs in turn via Bluetooth, and the binding information with all target TVs is stored and maintained;

[0037] This process is the binding link of Bluetooth pairing. The Bluetooth information of the three TVs are stored in the flash storage, and the binding information with the three TVs is saved to facilitate the subsequent direct connection of the TV to the remote control.

[0038] In this embodiment, in step S100, the specific method is:

[0039] S101. The remote control receives the Bluetooth broadcast packet of the target TV, and parses the new target TV Bluetooth broadcast packet, parses the new target TV Bluetooth MAC address and pairing key, and temporarily stores them in the data structure of the custom broadcast packet;

[0040] S102. The remote controller writes information of the target TV to achieve and maintain binding.

[0041] Preferably, the remote control writes the information of the target TV by calling the write function of the flash storage API interface.

[0042] S200. The remote control is aimed at the target TV and any button of the remote control is pressed. The target TV receives the infrared signal, analyzes the infrared signal, and sends a broadcast to the Bluetooth application. The TV and the remote control establish a Bluetooth connection and determine whether the TV needs to be switched. If so, enter S300, otherwise enter S400;

[0043] In this embodiment, it is determined that the remote controller is aimed at the target TV and any button of the remote controller is pressed, which is achieved by:

[0044] In the keycode.xml file of the target TV, the key values ​​of the infrared buttons are defined so that when the target TV receives any infrared button, it will add additional keycode value information to the infrared signal, and assign the additional keycode value to the Bluetooth application in the target TV for processing, and set a broadcast receiver in the Bluetooth application to monitor whether the remote control button is pressed by the remote control facing the target TV.

[0045] After all target TVs are paired with the remote control, you only need to point the remote control at a target TV and press the remote control to control it.

[0046] For example, when the remote control is aimed at the target TV and any button is pressed, the target TV broadcast receiver receives the infrared signal and calls

[0047] BluetoothAdapter.getBondedDeviceS interface, read the device array of the target TV's bound devices, and then call

[0048] BluetoothManager.getConnectDevices(BluetoothProfi le.GATT) interface to read the connection status of the bound devices respectively.

[0049] Furthermore, when the target TV currently has no connected device, the device.connectGatt(this, false, gattCallback) interface is called in sequence on the device array to connect the remote control. Because the remote control stores the binding relationship with the three target TVs, the connection will be very fast, and the connection will be established within 3 seconds. Subsequently, the remote control can be operated separately through the Bluetooth protocol.

[0050] S300. When the target TV needs to be switched, the remote controller only needs to point the remote controller toward the next target TV to be switched and press any button on the remote controller. After the TV receives the infrared signal, the above logic operation is repeated. The current target TV initiates a connection request to the remote controller. The remote controller compares the MAC address of the TV being connected with the key and the Bluetooth MAC address of the requested target TV. If the devices are different, the connection is disconnected and a new connection is re-established to achieve the purpose of fast switching, so as to establish a Bluetooth connection between the target TV and the remote controller.

[0051] It is worth noting that when using this method, when the remote control is using Bluetooth to control the target TV, be careful not to point the infrared signal at other TV buttons, otherwise it will switch to control other TVs.

[0052] S400. Remote control the target TV.

[0053] Example 2

[0054] A system for independently controlling multiple televisions with a single remote controller includes: target televisions and the remote controller are unobstructed and connected via Bluetooth binding, so as to implement the method for independently controlling multiple televisions with a single remote controller as described in Example 1.

[0055] Optionally, the remote control adopts an nRF52 microcontroller with built-in flash storage.

[0056] The present invention can accurately and independently control each TV through a single remote control when there are multiple TVs nearby, without the need for shielding objects to block the infrared receiver, and will not cause the TV to fail to respond or remotely control a non-target TV. The one-to-one effect of the Bluetooth remote control is achieved, and the tedious operation of unpairing and re-pairing the remote control is not required, thereby improving production efficiency and the convenience of using the scene of controlling multiple TVs.

[0057] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are only preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and embodiments, which will fall within the scope and spirit of the principles disclosed in this application.
