Abstract

The present application provides a pairing method for a control device and a display device, and a display device. After the user presses a button of the control device, the control device sends the button instruction to the display device in the form of an infrared signal. When the button instruction is a voice button instruction, after the display device receives the instruction, it needs to detect whether Bluetooth pairing has been performed with the control device; if Bluetooth pairing has not been performed, the display device can prompt the user to pair the control device with the display device through Bluetooth. Avoid the problem that the display device cannot provide voice services to the user due to failure to pair Bluetooth with the control device. After completing Bluetooth pairing, the display device can continue to receive voice button instructions sent by the control device, and can respond to the voice button instructions to display corresponding content or perform corresponding operations. Thereby ensuring the voice interaction experience between the user and the display device.

Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a method for pairing a control device with a display device and a display device. Background Art

[0002] With the development and in-depth research of display devices, the voice function of display devices is becoming more and more popular. Taking the Google Assistant of overseas display devices as an example, users can interact with the Google Assistant of display devices through remote controls and other control devices, which greatly facilitates user use.

[0003] The voice interaction between the remote control and the display device relies on the Bluetooth protocol, which requires the remote control to be paired with the display device before it can be used normally. When the display device or the remote control is unpaired or the connection is abnormal, the remote control will not be able to communicate with the display device via Bluetooth, which directly leads to the failure of the Google voice function. If users cannot use the voice function on the display device, it will greatly affect the user experience. Summary of the invention

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 display device 200 can establish transmission and reception of control signals and data signals with the control device 100 or the server 400 through the communicator 220.

[0073] In some embodiments, the detector 230 is used to collect signals of the external environment or external interaction. For example, the detector 230 includes a light receiver, a sensor for collecting the intensity of ambient light; or, the detector 230 includes an image collector, such as a camera, which can be used to collect external environment scenes, user attributes or user interaction gestures; or, the detector 230 includes a sound collector, such as a microphone, etc., for receiving external sounds.

[0074] In some embodiments, the external device interface 240 may include, but is not limited to, any one or more of the following interfaces: a high-definition multimedia interface (HDMI), an analog or digital high-definition component input interface (component), a composite video input interface (CVBS), a USB input interface (USB), an RGB port, etc. It may also be a composite input / output interface formed by the above multiple interfaces.

[0075] In some embodiments, the controller 250 and the tuner-demodulator 210 may be located in different separate devices, that is, the tuner-demodulator 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0076] In some embodiments, the controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in the memory. The controller 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 controller 250 can perform operations related to the object selected by the user command.

[0077] In some embodiments, the object may be any one of the selectable objects, such as a hyperlink, an icon or other operable controls. Operations related to the selected object include: displaying a page, document, image, etc. connected to the hyperlink, or executing a program corresponding to the icon.

[0078] In some embodiments, the controller includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), a RAM Random Access Memory (RAM), a ROM (Read-Only Memory, ROM), a first interface to an nth interface for input / output, a communication bus (Bus), etc.

[0079] The CPU processor is used to execute the operating system and application instructions stored in the memory, and to execute various applications, data and content according to various interactive instructions received from the outside, so as to finally display and play various audio and video contents. The CPU processor may include multiple processors. For example, it may include a main processor and one or more sub-processors.

[0080] In some embodiments, the graphics processor is used to generate various graphic objects, such as at least one of icons, operation menus, and user input command display graphics. The graphics processor includes an operator, which performs operations by receiving various interactive instructions input by the user and displays various objects according to display attributes; and a renderer, which renders various objects obtained based on the operator, and the rendered objects are used to be displayed on the display.

[0081] In some embodiments, the video processor is used to receive an external video signal and perform at least one of the following video processing operations, such as decompression, decoding, scaling, noise reduction, frame rate conversion, resolution conversion, and image synthesis, according to a standard codec protocol of the input signal, to obtain a signal that can be directly displayed or played on the display device 200.

[0082] In some embodiments, the video processor includes at least one of a demultiplexing module, a video decoding module, an image synthesis module, a frame rate conversion module, and a display formatting module. The demultiplexing module is used to demultiplex the input audio and video data stream. The video decoding module is used to process the demultiplexed video signal, including decoding and scaling. The image synthesis module, such as an image synthesizer, is used to superimpose and mix the GUI signal generated by the graphics generator according to the user input or itself with the scaled video image to generate an image signal for display. The frame rate conversion module is used to convert the input video frame rate. The display formatting module is used to receive the video output signal after frame rate conversion and change the signal to conform to the display format signal, such as outputting an RGB data signal.

[0083] In some embodiments, the audio processor is used to receive an external audio signal, perform decompression and decoding according to a standard codec protocol of the input signal, and perform at least one of noise reduction, digital-to-analog conversion, and amplification processing to obtain a sound signal that can be played in a speaker.

[0084] In some embodiments, the user may 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 may input a user command by inputting a specific sound or gesture, and the user input interface receives the user input command by recognizing the sound or gesture through a sensor.

[0085] In some embodiments, "user interface" is a medium interface for interaction and information exchange between an application or operating system and a user, which realizes the conversion between the internal form of information and the form acceptable to the user. A common form of user interface is a graphical user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be an interface element such as an icon, window, or control displayed on a display screen of an electronic device, wherein a control may include at least one of icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, and other visual interface elements.

[0086] In some embodiments, the user interface 280 is an interface that can be used to receive control input (such as a physical button on the display device body, or other interfaces).

[0087] See also Figure 4 In some embodiments, the system is divided into four layers, from top to bottom, namely, the application layer (Applications) layer (referred to as "application layer"), the application framework layer (Application Framework) layer (referred to as "framework layer"), the Android runtime (Android runtime) and system library layer (referred to as "system runtime library layer"), and the kernel layer.

[0088] In some embodiments, at least one application is running in the application layer, and these applications can be window programs, system settings programs, clock programs, etc. provided by the operating system, or applications developed by third-party developers. In specific implementations, the application packages in the application layer are not limited to the above examples.

[0089] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center that determines the actions that applications in the application layer take. Through the API interface, applications can access system resources and obtain system services during execution.

[0090] like Figure 4 As shown, in the embodiment of the present application, the application framework layer includes managers, providers, etc., wherein the manager includes at least one of the following modules: an activity manager (ActivityManager) is used to interact with all activities running in the system; a location manager (Location Manager) is used to provide system services or applications with access to system location services; a package manager (Package Manager) is used to retrieve various information related to the application package currently installed on the device; a notification manager (NotificationManager) is used to control the display and clearing of notification messages; a window manager (Window Manager) is used to manage icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0091] In some embodiments, the activity manager is used to manage the life cycle of each application and the common navigation back function, such as controlling the exit, opening, and back of the application. The window manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, capturing the screen, and controlling the display window changes (for example, reducing the display window, shaking the display, distorting the display, etc.).

[0092] In some embodiments, the system runtime layer provides support for the upper layer, namely the framework layer. When the framework layer is used, the Android operating system will run the C / C++ library contained in the system runtime layer to implement the functions to be implemented by the framework layer.

[0093] In some embodiments, the kernel layer is a layer between hardware and software. Figure 4 As shown, the kernel layer includes at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver, etc.

[0094] As the development and research of the display device 200 continues to deepen, the voice function of the display device 200 is becoming more and more popular. Taking the Google Voice Assistant (Google Assistant) of the overseas display device 200 as an example, the user can perform voice interaction with the Google Voice Assistant of the display device 200 through the control device 100 such as a remote control, which greatly facilitates the user's use.

[0095] The voice interaction between the remote control and the display device 200 depends on the Bluetooth protocol, which requires the remote control to be paired with the display device 200 before normal use. When the display device 200 or the remote control is unpaired or the connection is abnormal, the remote control will not be able to achieve Bluetooth communication with the display device 200, which directly leads to the failure of the Google voice function. If users cannot use the voice function on the display device 200, it will greatly affect the user experience.

[0096] Based on the above, the embodiment of the present application provides a display device 200, which can transmit key commands to a control device 100 such as a remote controller based on infrared signals. Moreover, when a user presses different keys on the control device 100, the control device 100 sends different key commands to the display device 200.

[0097] Since the voice service needs to be based on the Bluetooth communication protocol, after receiving the voice key command sent by the control device 100, the display device 200 will first determine whether the control device 100 has been paired with the display device 200 by Bluetooth. Only on the basis of Bluetooth pairing, the display device 200 can respond to the voice key command input by the user based on the Bluetooth communication protocol and interact with the user according to the voice content input by the user in subsequent operations. If the control device 100 is not paired with the display device 200 by Bluetooth, the display device 200 will provide the user with a Bluetooth pairing prompt so that the user can complete the Bluetooth pairing of the control device 100 and the display device 200, and after the Bluetooth pairing of the control device 100 and the display device 200 is completed, the display device 200 can continue to receive and respond to voice key commands.

[0098] A voice button is usually provided on the control device 100. When the control device 100 and the display device 200 have been paired with Bluetooth, the user presses the voice button once to control the display device 200 to display the voice service page; when the user long presses the voice button, the control device 100 can receive the voice content input by the user, and send the voice content to the display device 200 after the user releases the voice button, so as to control the display device 200 to perform corresponding operations.

[0099] See also Figure 5 , Figure 5A schematic diagram of a control device 100 according to some embodiments is shown. In addition to direction keys, confirmation keys, return keys, menu keys, home keys, power keys, volume keys, etc., the control device 100 is also provided with a voice key with a microphone logo.

[0100] See also Figure 6 , Figure 6 A schematic diagram of Bluetooth pairing of the display device 200 and the control device 100 according to some embodiments is shown. In the process of Bluetooth pairing of the display device 200 and the control device 100, the controller 250 of the display device 200 can be configured to: upon receiving a voice key command input by the user to the display device 200 through the control device 100, detect whether the control device 100 and the display device 200 are Bluetooth paired. Then, in the case where the control device 100 and the display device 200 are not Bluetooth paired, prompt the user to Bluetooth pair the control device 100 and the display device 200. Finally, in the case where the user completes the Bluetooth pairing of the control device 100 and the display device 200, continue to receive the voice key command input by the user to the display device 200 through the control device 100.

[0101] In some embodiments, in order to facilitate prompting the user to pair the control device 100 with the display device 200 through Bluetooth, the display device 200 may further display a pairing prompt page to the user when it detects that it has not been paired with the control device 100 through Bluetooth. Different options may be displayed on the pairing prompt page so that the user can choose whether to pair the control device 100 with the display device 200 through Bluetooth.

[0102] See also Figure 7 , Figure 7 A schematic diagram of a pairing prompt page according to some embodiments is shown. The pairing prompt page displays a first cancel option for canceling the pairing, and also displays a first setting option for entering the setting page. If the user selects the first cancel option on the pairing prompt page, it means that the user does not need or want to perform Bluetooth pairing between the control device 100 and the display device 200. At this time, the display device 200 can respond to the first cancel instruction and not perform Bluetooth pairing with the control device 100. If the user selects the first setting option on the pairing prompt page, it means that the user wants to perform Bluetooth pairing between the control device 100 and the display device 200. At this time, the display device 200 can further respond to the first setting instruction and display the setting page so that the user can perform further pairing operations according to the content of the setting page.

[0103] When the display device 200 receives the first cancellation command, it does not perform Bluetooth pairing with the control device 100. However, in order to avoid the situation where the user wants to perform the Bluetooth pairing operation again but cannot find the setting page, the display device 200 can continue to display the unpairing prompt page when receiving the first cancellation command. The unpairing prompt page can still display a second cancellation option for canceling the Bluetooth pairing and a second setting option for performing the setting page.

[0104] See also Figure 8 , Figure 8 A schematic diagram of an unpaired prompt page according to some embodiments is shown. If the user selects the second cancel instruction on the unpaired prompt page, it means that the user still does not need or want to perform Bluetooth pairing between the control device 100 and the display device 200. At this time, the display device 200 can respond to the second cancel instruction and not perform Bluetooth pairing with the control device 100. If the user selects the second setting option on the pairing prompt page, it means that the user wants to perform Bluetooth pairing between the control device 100 and the display device 200 at this time. The display device 200 can further respond to the second setting instruction and display the setting page so that the user can perform further pairing operations according to the content of the setting page.

[0105] See also Fig. 9 , Fig. 9 A schematic diagram of the display device 200 displaying an unpaired prompt page according to some embodiments is shown. In the process of displaying the unpaired prompt page, the controller 250 of the display device 200 may also be configured to: control the display 260 to display the pairing prompt page when the control device 100 and the display device 200 are not paired with Bluetooth. And, when receiving a first cancel instruction input by the user on the pairing prompt page for selecting a first cancel option, control the display 260 to display the unpaired prompt page.

[0106] In some embodiments, if the display device 200 displays the pairing prompt page and the user does not input any instructions to the display device 200 within a preset time, the display device 200 will also display an unpaired prompt page to prompt the user to continue the Bluetooth pairing operation. The preset time is a time configured by the display device 200 itself, such as 5 seconds, 3 seconds, etc.

[0107] In this case, the controller 250 of the display device 200 may be configured to control the display 260 to display the unpairing prompt page if no instruction input by the user on the prompt page is received within a preset time.

[0108] If the user needs to pair the control device 100 with the display device 200 via Bluetooth after viewing the pairing prompt page, the user can select a first setting option on the pairing prompt page, and then input a first setting instruction to the display device 200. Then, the display device 200 displays a setting page in response to the first setting instruction. The setting page is usually used to guide the user to press a target button on the control device to complete the Bluetooth pairing operation, for example, pressing the volume "+" button and the return button at the same time, pressing the blue button and the yellow button at the same time, etc.

[0109] See also Fig.10 , Fig.10 A schematic diagram of a setting page according to some embodiments is shown. The prompt information displayed on the setting page is "Press the [blue] and [yellow] buttons on the remote control to complete the pairing". The user presses the blue button and the yellow button on the remote control at the same time, thereby inputting a pairing instruction to the display device 200. Then, the display device 200 responds to the pairing instruction and performs Bluetooth pairing with the control device 100.

[0110] See also Fig.11 , Fig.11 Another schematic diagram of Bluetooth pairing of the display device 200 and the control device 100 according to some embodiments is shown. In the process of Bluetooth pairing of the display device 200 and the control device 100, the controller 250 of the display device 200 is further configured to: upon receiving a first selection instruction for selecting a first setting option input by a user on the pairing prompt page, control the display 260 to display the setting page. Then, in response to the pairing instruction input by the user pressing a target button on the control device 100, the control device 100 and the display device 200 are Bluetooth paired.

[0111] In some embodiments, if the display device 200 detects that the display device 200 has been Bluetooth paired with the control device 100 after receiving the voice button command sent by the control device 100, then the display device 200 can directly respond to the voice button command and display the voice service page, thereby indicating that the display device 200 has entered the voice service state and can receive voice content input by the user.

[0112] The voice service page usually displays prompt information to provide users with voice input content. Fig.12 , Fig.12A schematic diagram of a voice service page according to some embodiments is shown. The voice service page displays some prompts of voice content that can be input, such as "What's the weather like this week?", "What's the weather like tomorrow?", "When will it rain?", etc. After the user inputs specific voice content to the display device 200, the display device 200 recognizes the voice content through the voice service, performs corresponding operations, and displays corresponding content for the user.

[0113] For example, the voice content input by the user to the display device 200 is "What will the weather be like tomorrow?", the voice service of the display device 200 will recognize the specific voice content and perform semantic analysis, etc., obtain tomorrow's weather information from the server, and finally display tomorrow's weather information to the user.

[0114] See also Fig.13 , Fig.13 A schematic diagram of the display device 200 responding to a voice key command according to some embodiments is shown. In the above process of responding to the voice key command, the controller 250 of the display device 200 can also be configured to: first, upon receiving the voice key command input by the user to the display device 200 through the control device 100, detect whether the control device 100 and the display device 200 are paired by Bluetooth. Then, in the case where the control device 100 and the display device 200 have been paired by Bluetooth, in response to the voice key command, control the display 260 to display the voice service page.

[0115] In the aforementioned embodiment, if the user completes the Bluetooth pairing of the control device 100 and the display device 200 through the Bluetooth pairing operation, the display device 200 can continue to receive the voice key command sent by the control device 100. At this time, since the control device 100 has been paired with the display device 200 through Bluetooth, the display device 200 can directly respond to the voice key command and display the voice service page. In this process, the controller 250 of the display device 200 can be configured as follows: first, when the user completes the Bluetooth pairing of the control device 100 and the display device 200, continue to receive the voice key command input by the user to the display device 200 through the control device 100. Then, in response to the voice key command, control the display 260 to display the voice service page.

[0116] In some embodiments, if the user still selects the second cancel option after the display device 200 displays the unpaired prompt page, the display device 200 can close the unpaired prompt page, and the display device 200 and the control device 100 are still unpaired. Alternatively, if the user still does not enter any instructions on the unpaired prompt page within a preset time, the display device 200 can also close the unpaired prompt page, and the display device 200 and the control device 100 are still unpaired. In this process, the controller 250 of the display device 200 can be configured to: when the display 260 displays the unpaired prompt page, detect whether a second cancel instruction input by the user for selecting the second cancel option is received. And, when the user receives the second cancel instruction, control the display 260 to close the unpaired prompt page. Alternatively, when the display 260 displays the unpaired prompt page, detect that no instructions entered by the user on the unpaired prompt page are received within a preset time, and control the display 260 to close the unpaired prompt page.

[0117] In some embodiments, if the display device 200 displays the unpaired prompt page and the user needs to pair the display device 200 with the control device 100 via Bluetooth, the user can select the second setting option on the unpaired prompt page, and then control the display device 200 to display the setting page, so that the user can complete the Bluetooth pairing operation according to the guidance content on the setting page. In this process, the controller 250 of the display device 200 can be configured to: when the display 260 displays the unpaired prompt page, detect whether a second selection instruction for selecting the second setting option input by the user is received; and, when the user receives the second selection instruction, control the display 260 to display the setting page.

[0118] From the above, it can be seen that the display device 200 in the embodiment of the present application can receive the key command sent by the control device 100 such as a remote controller through an infrared signal. In addition, when the key command is a voice key command, after receiving the command, the display device 200 needs to detect whether Bluetooth pairing with the control device 100 has been performed; if Bluetooth pairing has not been performed, the display device 200 can prompt the user to perform Bluetooth pairing with the control device 100. This avoids the problem that the display device 200 cannot provide voice services to the user due to failure to perform Bluetooth pairing with the control device 100.

[0119] After the Bluetooth pairing is completed, the display device 200 can continue to receive the voice key command sent by the control device 100, and can display the corresponding content or perform the corresponding operation in response to the voice key command, thereby ensuring the voice interaction experience between the user and the display device 200.

[0120] In order to solve the problem that the user cannot use the voice function on the display device 200 due to the display device 200 and the control device 100 not being paired, the embodiment of the present application also provides a pairing method of the control device and the display device, which can be applied to the display device 200 in the above embodiment.
