[0056] According to implementation requirements, the application scenario in the embodiment of the present application may have any number of display devices 200 and radio frequency remote control devices 100. For example, multiple display devices 200 may be provided, and the multiple display devices 200 together form a display device group.

[0057] Figure 2 This is a hardware configuration block diagram of a display device provided in an embodiment of the present application. Figure 2 , the display apparatus 200 includes a tuner and demodulator 210, a communicator 220, a detector 230, an external device interface 240, a processor 250, a display 260, a speaker 270, a memory 280, a user interface 290, and a power supply.

[0058] The communicator 220 is a component for communicating with an external device or server according to various communication protocol types. For example, the communicator may include at least one of a Wifi module, a Bluetooth module, a wired Ethernet module, and other network communication protocol chips or near field communication protocol chips, and an infrared receiver. The communicator 220 is used to communicate with a radio frequency remote control device, and the display device 200 can establish the transmission and reception of control signals and data signals with the radio frequency remote control device or server through the communicator 220.

[0059] The speaker 270 includes a broadcasting component for playing audio and a driving component for driving audio playback, and is used to receive an audio signal output from the processor 250 to perform audio playback.

[0060] The display 260 includes a display screen component for presenting images, a driving component for driving image display, a component for receiving an image signal output from the processor 250, and a component for displaying video content, image content, and a menu control interface, and a user control UI interface, etc. The user can input a user command in a graphical user interface (GUI) displayed on the display 260, and the user input interface receives the user input command through the graphical user interface (GUI). Alternatively, the user can input a user command by inputting a specific sound or gesture, and the user input interface recognizes the sound or gesture through a sensor to receive the user input command.

[0061] In some embodiments, the display 260 may be at least one of a liquid crystal display, an OLED display, and a projection display, and may also be a projection device and a projection screen.

[0062] The memory 280 is used to store data related to the connection with the radio frequency remote control device, specifically, to store data or program codes used when the display device is running or connected with the radio frequency remote control device, and may include a readable medium in the form of a volatile memory. For example, a random access memory and / or a cache memory, and may further include a read-only memory. The memory 280 may also include a program / utility of at least one program module, such a program module includes but is not limited to: an operating system, one or more application programs, other program modules, and program data, each of these examples or some combination thereof may include the implementation of a network environment.

[0063] The processor 250 controls the operation of the display device 200 and responds to the user's operation through various software control programs stored in the memory 280. The processor 250 controls the overall operation of the display device 200. For example, in response to receiving a user command for selecting a UI object to be displayed on the display 260, the processor 250 may perform an operation related to the object selected by the user command.

[0064] In the embodiment of the present application, the processor 250 includes a central processing unit, a video processor, an audio processor, a graphics processor, a RAM, a ROM, and a first interface to an nth interface for input / output.

[0065] In an embodiment of the present application, the processor 250 of the display device 200 is used to: respond to the user's pairing operation, make the speaker 270 play the audio containing the first identification information, and search for the radio frequency remote control device; obtain the device information broadcasted by the searched radio frequency remote control device; determine whether the device information contains the second identification information; if the device information of the radio frequency remote control device contains the second identification information, send a connection establishment request to the radio frequency remote control device, and establish a connection with the radio frequency remote control device when the radio frequency remote control device responds to the connection establishment request. The second identification information is generated by the radio frequency remote control device according to the first identification information.

[0066] Preferably, the display device 200 may be a smart TV, and the radio frequency remote control device may be a Bluetooth remote control.

[0067] When the user performs a pairing operation by performing human-computer interaction with the display device 200, the processor 250 of the display device 200 responds to the user's pairing operation and sends an audio play instruction to the speaker 270, so that the speaker 270 receiving the audio play instruction plays the audio containing the first identification information. When the speaker 270 plays the audio containing the first identification information, the processor 250 of the display device 200 searches for a radio frequency remote control device. After searching for several radio frequency remote control devices, the processor 250 of the display device 200 obtains the device information broadcasted by the searched radio frequency remote control device, identifies the obtained device information, and determines whether the device information of the corresponding radio frequency remote control device includes the second identification information according to the identification result. If the device information of the radio frequency remote control device is identified to include the second identification information, a connection establishment request is sent to the radio frequency remote control device, and a connection is established with the radio frequency remote control device when the radio frequency remote control device returns a signal agreeing to establish the connection.

[0068] It should be noted that, when the RF remote control device receives audio containing first identification information played by the speaker 270, it can extract the first identification information from the received audio, and then generate second identification information based on the first identification information, write the generated second identification information into its own device information and broadcast the device information written with the second identification information, so that the processor 250 of the display device 200 in the same physical area as the RF remote control device can obtain the device information of the RF remote control device by searching for the RF remote control device, and determine whether the device information contains the second identification information.

[0069] In some embodiments, the processor 250 of the display device 200 is also used to: randomly generate first identification information when a user's pairing operation is detected; generate an audio playback instruction based on the generated first identification information and send it to the speaker 270, so that the speaker 270 plays audio containing the first identification information; and save the first identification information and device information in the memory 280.

[0070] When the user performs a pairing operation by performing human-computer interaction with the display device 200, the processor 250 of the display device 200 can detect the user's pairing operation and randomly generate first identification information within a preset identification information interval, and the generated first identification information is a random value. The processor 250 of the display device 200 generates an audio playback instruction based on the generated first identification information and sends it to the speaker 270. The speaker 270 can parse the corresponding first identification information from the audio playback instruction and play the audio containing the first identification information based on the parsed first identification information. When the radio frequency remote control device receives the audio containing the first identification information and broadcasts its device information, the processor 250 of the display device 200 can identify the device information containing the second identification information from the device information of multiple radio frequency remote control devices, and save the first identification information and the device information containing the second identification information in the memory 280.

[0071] Preferably, the first identification information may be a frequency value of the audio or voice information in the audio.

[0072] Preferably, the device information is a device name of the radio frequency remote control device, and the second identification information device name is a character generated according to the first identification information.

[0073] In the embodiment of the present application, the first identification information is the frequency value of the audio played by the speaker 270 .

[0074] When the user performs a pairing operation by performing human-computer interaction with the display device 200, the processor 250 of the display device 200 responds to the user's pairing operation and randomly generates first identification information within a preset frequency value interval. The generated first identification information is a random frequency value. The generated first identification information is encapsulated in an audio playback instruction and sent to the speaker 270. The speaker 270 parses the corresponding first identification information from the audio playback instruction and plays the audio of the frequency value corresponding to the first identification information according to the parsed first identification information. Subsequently, the processor 250 of the display device 200 searches for a radio frequency remote control device. When several radio frequency remote control devices are searched and the device information of the radio frequency remote control device is identified to contain the second identification information (the second identification information is a character according to the frequency value corresponding to the first identification information), a connection establishment request is sent to the radio frequency remote control device, and a connection is established with the radio frequency remote control device when the radio frequency remote control device returns a signal agreeing to establish a connection.

[0075] In some embodiments, the processor 250 of the display device 200 is also used to: when detecting a user's pairing operation, generate pairing start information and send it to the speaker 270 and / or the display of the display device 200, so that the speaker 270 plays audio containing a pairing start logo and / or the display of the display device 200 displays a screen containing a pairing start logo; when establishing a connection with the radio frequency remote control device, generate pairing completion information and send it to the speaker 270 and / or the display of the display device 200, so that the speaker 270 plays audio containing a pairing completion logo and / or the display of the display device 200 displays a screen containing a pairing completion logo.

[0076] When the user performs a pairing operation by performing human-computer interaction with the display device 200, the processor 250 of the display device 200 responds to the user's pairing operation and generates a pairing start message, which may be sent to the speaker 270 so that the speaker 270 plays an audio containing a pairing start mark, or the pairing start message may be sent to the display so that the display displays a screen containing a pairing start mark to prompt the user that the pairing operation is being performed. When establishing a connection with the RF remote control device, the processor 250 of the display device 200 generates a pairing completion message, which may be sent to the speaker 270 so that the speaker 270 plays an audio containing a pairing completion mark, or the pairing completion message may be sent to the display so that the display displays a screen containing a pairing completion mark to prompt the user that the pairing operation is being performed, to prompt the user that the pairing operation is completed.

[0077] Figure 3 This is a hardware configuration block diagram of the radio frequency remote control device provided in the embodiment of the present application. Figure 3 The radio frequency remote control device 100 includes a processor 110, a sound collector 120, a communicator 130, an input / output interface 140, a memory 150, an information extractor 160 and a power supply.

[0078] The radio frequency remote control device 100 can receive the user's input operation instructions, and convert the operation instructions into instructions that can be recognized and responded to by the display device, playing the role of an intermediary for the interaction between the user and the display device.

[0079] The communicator 130 is used to communicate with the display device and is at least one of a WIFI communication module, a Bluetooth communication module, an NFC communication module or an alternative module.

[0080] The memory 150 is used to store device information of the RF remote control device 100 and store data related to the connection between the RF remote control device 100 and the display device.

[0081] The sound collector 120 is used to collect external audio, and the sound collector 120 is a microphone.

[0082] The information extractor 160 is used to extract feature information from the audio. The information extractor 160 is a speech recognition chip or a sound frequency recognition device.

[0083] The input / output interface 140 includes at least one of a touch panel, a sensor, a button, or a replaceable module.

[0084] In an embodiment of the present application, the processor 110 of the radio frequency remote control device 100 is used to: respond to the user's pairing operation, so that the sound collector 120 collects external audio, and the information extractor 160 extracts characteristic information from the collected audio; obtains the characteristic information extracted from the collected audio; generates corresponding identification information according to the characteristic information and writes it into the device information, and broadcasts the device information written with the corresponding identification information through the communicator; responds to the connection establishment request sent by the display device to establish a connection with the display device. The connection establishment request is sent by the display device when it is determined that the device information of the radio frequency remote control device 100 contains the second identification information, the second identification information is generated by the radio frequency remote control device 100 according to the first identification information, and the first identification information is the characteristic information contained in the audio played by the display device.

[0085] When the user performs a pairing operation by performing human-computer interaction with the RF remote control device 100, the processor 110 of the RF remote control device 100 responds to the user's pairing operation, sends an audio collection instruction to the sound collector 120 and sends an information extraction instruction to the information extractor 160, so that the sound collector 120 collects external audio and sends the collected audio to the information extractor 160, and the information extractor 160 extracts feature information from the received audio and sends the extracted feature information to the processor 110 of the RF remote control device 100. The processor 110 of the RF remote control device 100 generates corresponding identification information according to the feature information, writes the generated identification information into the device information of the RF remote control device 100, and broadcasts the device information written with the identification information through the communicator, so that the processor 110 of the display device in the same physical area as the RF remote control device 100 can obtain the device information of the RF remote control device 100 by searching the RF remote control device 100, and judge whether the device information contains the second identification information. If the sound collector 120 collects the audio containing the first identification information played by the display device, the information extractor 160 can extract the first identification information from the received audio, and the processor 110 of the RF remote control device 100 can generate the second identification information according to the first identification information, write the second identification information into the device information of the RF remote control device 100 and broadcast it. The display device searches for the RF remote control device 100 to obtain the device information broadcasted by the searched RF remote control device 100, identifies the obtained device information, and determines whether the device information of the corresponding RF remote control device 100 contains the second identification information according to the identification result. If it is identified that the device information of the RF remote control device 100 contains the second identification information, a connection establishment request is sent to the RF remote control device 100, and a connection is established with the RF remote control device 100 when the RF remote control device 100 returns a signal agreeing to establish the connection.

[0086] In some embodiments, the processor 110 of the RF remote control device 100 is also used to: when a connection is established with a display device and a user's pairing operation is detected, clear the data related to the display device connection in the memory 150, respond to the current pairing operation, enable the sound collector 120 to collect external audio, and enable the information extractor 160 to extract feature information from the collected audio.

[0087] After the RF remote control device 100 establishes a connection with the display device, when the user performs a pairing operation by performing human-computer interaction with the RF remote control device 100, the processor 110 of the RF remote control device 100 responds to the user's pairing operation, clears the data related to the display device connection in the memory 150 to release the connection relationship established with the current display device, and re-sends the audio collection instruction to the sound collector 120 and re-sends the information extraction instruction to the information extractor 160, so that the sound collector 120 collects external audio and sends the collected audio to the information extractor 160, and the information extractor 160 extracts feature information from the received audio and sends the extracted feature information to the processor 110 of the RF remote control device 100, and re-generates corresponding identification information based on the feature information, writes the generated identification information into the device information of the RF remote control device 100, and broadcasts the device information written with the identification information through the communicator.

[0088] In the embodiment of the present application, the device information is the device name of the radio frequency remote control device 100, and the second identification information device name is a character generated according to the first identification information.

[0089] Preferably, the first identification information is a frequency value of the audio played by the speaker.

[0090] When the user performs a pairing operation by performing human-computer interaction with the RF remote control device 100, the processor 110 of the RF remote control device 100 responds to the user's pairing operation, causes the sound collector 120 to collect external audio, and causes the information extractor 160 to extract the frequency value in the collected audio. The processor 110 of the RF remote control device 100 obtains the frequency value in the extracted and collected audio, generates a corresponding character representing the frequency value according to the frequency value of the audio, writes the character into the device name of the RF remote control device 100, and broadcasts the device name in which the character representing the frequency value is written through the communicator. If the user performs a pairing operation by performing human-computer interaction with the display device, so that the display device plays audio with a frequency value corresponding to the first identification information, the sound collector 120 collects the audio played by the display device, and the information extractor 160 extracts the frequency value corresponding to the first identification information from the collected audio. The processor 110 of the RF remote control device 100 converts the frequency value corresponding to the first identification information into a character form and writes it into the device name of the RF remote control device 100, and broadcasts the device name with the characters representing the frequency value through the communicator. For example, when the display device plays audio with a frequency value of 12345 Hz, the processor 110 of the RF remote control device 100 updates the device name to "RCU-12345" and broadcasts it. The display device can obtain the device name of the RF remote control device 100 by searching for the RF remote control device 100, and determine whether the device name of the RF remote control device 100 contains the second identification information by extracting the numeric characters of the device name and matching them with the frequency value corresponding to the first identification information. For example, the display device plays audio with a frequency value of 12345 Hz, and the device name of the RF remote control device 100 is "RCU-12345". The numeric characters "12345" of the device name are matched with "12345 Hz". The matching result is that the device name of the RF remote control device 100 contains the second identification information. The display device sends a connection establishment request to the RF remote control device 100, and the RF remote control device 100 responds to the connection establishment request sent by the display device and returns a signal agreeing to establish the connection, so as to establish a connection with the display device.

[0091] In some embodiments, the processor 110 of the RF remote control device 100 is also used to: when detecting the end of the pairing operation input by the user or when no connection is established with the display device after the preset waiting time, stop the sound collector 120 from collecting external audio and stop the information extractor 160 from extracting feature information from the collected audio; or when establishing a connection with the display device, stop the sound collector 120 from collecting external audio and stop the information extractor 160 from extracting feature information from the collected audio, and save the first identification information and the device information written into the second identification information in the memory 150.

[0092] When the processor 110 of the RF remote control device 100 detects the end pairing operation input by the user or fails to establish a connection with the display device after the preset waiting time, it sends a stop audio collection instruction to the sound collector 120 and a stop information extraction instruction to the information extractor 160, so that the sound collector 120 stops collecting external audio and the information extractor 160 stops extracting feature information from the collected audio. When establishing a connection with the display device, the processor 110 of the RF remote control device 100 sends a stop audio collection instruction to the sound collector 120 and a stop information extraction instruction to the information extractor 160, so that the sound collector 120 stops collecting external audio and the information extractor 160 stops extracting feature information from the collected audio, and saves the first identification information and the device information written into the second identification information in the memory 150.
