Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a method for switching between a display device and an audio output device. Background Art

[0002] Display devices are intelligent devices that can present user interfaces and support user interaction. Taking smart TV as an example, smart TV is based on Internet application technology, has an open operating system and chip, has an open application platform, can realize two-way human-computer interaction, and integrates multiple functions such as audio and video, entertainment, and data to meet the diverse and personalized needs of users.

[0003] The display device can be configured with a demonstration function. In some application scenarios, the display device can demonstrate the functions it supports to show them to the user. For example, in the scenario of a shopping mall, in order to better promote the display device to consumers, the seller can demonstrate the sound quality, picture quality and other functions of the display device by playing video images, etc., so that users can understand the product. When demonstrating the sound quality effect, the display device can play audio through the local speakers, or through an external speaker, or through the local speakers and external speakers at the same time. The user can use the remote control to control the display device to switch the device used when playing audio.

[0004] In a shopping mall scenario, sellers can show users multiple display devices so that users can choose the right one. Users may have different demonstration requirements for different display devices, such as requiring some display devices to play audio through local speakers and some display devices to play audio through speakers. However, in a shopping mall scenario, multiple display devices may be controlled by one remote control. When the user instructs the display device to switch audio devices through the remote control, multiple display devices will respond and use the same type of device to play audio, making it impossible to control the audio device of each display device individually.

[0076] In some embodiments, the mobile terminal 300 or other electronic devices may also simulate the functions of the control device 100 by running an application program for controlling the display device 200 .

[0077] like Figure 1 As also shown in FIG. 4 , the display device 200 also communicates data with the server 400 through various communication methods. The display device 200 may be allowed to communicate and connect through a local area network (LAN), a wireless local area network (WLAN), and other networks.

[0078] The display device 200 may provide a broadcast receiving television function, and may also additionally provide an intelligent network television function with a computer support function, including but not limited to network television, smart television, Internet Protocol television (IPTV), and the like.

[0079] Figure 2 A hardware configuration block diagram of a display device in some embodiments is shown.

[0080] In some embodiments, the display device 200 may include at least one of a tuner 210, a communication device 220, a detector 230, a device interface 240, a controller 250, a display 260, an audio output device 270, a memory, a power supply, and a user input interface.

[0081] 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.

[0082] In some embodiments, the display 260 includes a display function component for presenting a picture, and a driving component for driving an image display. The display 260 is used to receive an image signal output from the controller 250 for display. For example, the display 260 can be used to display video content, image content, and components of a menu control interface and a user control UI interface.

[0083] In some embodiments, the communication device 220 is a component for communicating with an external device or server 400 according to various communication protocol types. The display device 200 may be provided with a plurality of communication devices 220 according to different supported communication modes. For example, when the display device 200 supports wireless network communication, the display device 200 may be provided with a communication device 220 including a WiFi function. When the display device 200 supports Bluetooth connection communication, the display device 200 needs to be provided with a communication device 220 including a Bluetooth function.

[0084] The communication device 220 can enable the display device 200 to communicate with the external device or server 400 by wireless or wired connection. Among them, the wired connection can connect the display device 200 with the external device through components such as data cables and interfaces. The wireless connection can connect the display device 200 with the external device through wireless signals or wireless networks. The display device 200 can establish a connection relationship with the external device directly, or indirectly establish a connection relationship through a gateway, a router, a connection device, etc.

[0085] In some embodiments, the controller 250 may include at least one of a central processing unit, a video processor, an audio processor, a graphics processor, and a power processor, and a first interface to an nth interface for input / output. The controller 250 controls the operation of the display device and responds to the user's operation through various software control programs stored in the memory. The controller 250 controls the overall operation of the display device 200.

[0086] 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.

[0087] In some embodiments, the user may input a user command through 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).

[0088] In some embodiments, the audio output device 270 may be a local speaker of the display device 200, or may be an external audio output device of the display device 200. In particular, for the external audio output device of the display device 200, the display device 200 may also be provided with an external audio output terminal, and the audio output device may be connected to the display device 200 through the external audio output terminal to output the sound of the display device 200.

[0089] In some embodiments, the user input interface 280 may be used to receive instructions from a user.

[0090] In order to perform user interaction, in some embodiments, the display device 200 may run an operating system. The operating system is a computer program for managing and controlling hardware resources and software resources in the display device 200. The operating system can control the display device to provide a user interface, for example, the operating system can directly control the display device to provide a user interface, or can provide a user interface by running an application program. The operating system also allows the user to interact with the display device 200.

[0091] It should be noted that the operating system may be a native operating system based on a specific operating platform, or a third-party operating system deeply customized based on a specific operating platform, or an independent operating system specially developed for the display device.

[0092] The operating system can be divided into different modules or layers according to the functions implemented. Figure 3 FIG. 4 shows a software configuration diagram of a display device in some embodiments, such as Figure 3 As shown, in some embodiments, the system of the display device 200 can be divided into three layers, namely, an application layer, a middleware layer, and a hardware layer from top to bottom.

[0093] The application layer mainly includes applications on the TV and the application framework. Among them, applications are mainly applications developed based on the browser, such as HTML5 APPs and native applications.

[0094] The Application Framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange, etc., as well as the user interfaces of these functions (toolbars, status bars, menus, dialog boxes).

[0095] Native apps can support online or offline, message push or local resource access.

[0096] The middleware layer includes various TV protocols, multimedia protocols, system components and other middleware. The middleware can use the basic services (functions) provided by the system software to connect various parts of the application system or different applications on the network, and can achieve the purpose of resource sharing and function sharing.

[0097] The hardware layer mainly includes HAL interface, hardware and driver. Among them, HAL interface is the unified interface for all TV chips to connect, and the specific logic is implemented by each chip. Drivers mainly include: 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.

[0098] It should be noted that the above example is only a simple division of the operating system functions and does not constitute a limitation on the specific operating system form of the display device 200 in the embodiment of the present application. Depending on factors such as the function of the display device and the type of operating system, the number of levels and specific level types contained in the operating system may be expressed in other forms.

[0099] The display device 200 may have multiple functions, such as browsing web pages, playing media resources, entertainment games, screen projection, etc., so as to provide users with a variety of services. The user may control the display device 200 to start a related application program, thereby opening the corresponding function.

[0100] Taking the media playback function as an example, the display device 200 can play videos from different storage sources. For example, the display device 200 can play media data through a media playback application, and the media data can come from a cloud storage server or from a local hard disk storage containing stored video programs.

[0101] During use, the display device 200 can communicate with the server 400 to implement data interaction, including receiving various data sent by the server 400. For example, the display device 200 can obtain media asset data in the network through the server 400.

[0102] In order to realize data interaction between the display device 200 and the server 400, the display device 200 needs to establish a communication connection with the server 400. For example, the display device 200 and the server 400 can both be connected to the Internet, and the interactive data is transmitted between the display device 200 and the server 400 through the Internet transmission protocol. When the display device 200 receives the interactive data transmitted by the server 400, it first obtains the instructions or notifications contained in the interactive data, and then obtains other data to execute the corresponding interactive logic.

[0103] Figure 4 Schematic diagram showing the interaction between a display device and a server in some embodiments. Figure 4 As shown, components for establishing a communication connection need to be provided on the display device 200 and the server 400, respectively. A communication device 220 is provided in the display device 200, and a communication module 410 may be provided in the server 400. The communication device 220 and the communication module 410 may support at least one of the same communication modes at the same time to establish a communication connection relationship. For example, the communication device 220 on the display device 200 includes an optical fiber interface for connecting to a network; at the same time, the communication module 410 of the server 400 also includes an optical fiber interface to realize a communication connection between the display device 200 and the server 400.

[0104] In some embodiments, when the user controls the display device to start up, the controller 250 can control the display 260 to display a user interface. The user interface can be a specific target image, such as various media resources obtained from a network signal source, including videos, pictures and other content. The user interface can also be some UI interfaces of the display device, such as the system main interface, various control interfaces of applications installed in the display device, etc.

[0105] The display device can display the application list interface to the user, receive the application startup instruction input by the user based on the application list interface, and then run the corresponding application in response to the startup instruction, so that the display device 200 supports the application function. It should be noted that the application installed in the display device 200 can be a system application or a third-party application. The user controls the display device 200 to implement the corresponding function of an application by opening an application.

[0106] Figure 5 Schematic diagrams of application list interfaces in some embodiments are shown. Figure 5 As shown, the application list interface includes three controls: "Cable TV", "Network Media" and "Local Files". The display device 200 implements different functions by detecting the user's touch operation. In response to the user's touch operation on the "Cable TV" control, the display device 200 can display the media channel interface so that the user can select a media channel to play. In response to the user's touch operation on the "Network Media" control, the display device 200 can start the network media application to play various network media. In response to the user's touch operation on the "Local Files" control, the display device 200 starts the local file application to display various locally stored data, including locally stored video, audio, pictures and other content.

[0107] In some embodiments, the display device 200 may be configured with a plurality of modes to suit different usage environments and user requirements.

[0108] Shopping malls are an important means of product display, and users can learn about the functions and information of products through the products displayed in the mall. The mall includes an electronic product display area for displaying electronic products, such as televisions, mobile phones and other display devices. For users who have the need to purchase display devices, they can manipulate the display device prototypes displayed by the seller in the offline mall, experience the various functions of the display device, and understand the product information. For example, a user can play media through a display device to view the actual effect of the display device playing the media. Considering that the user may not be familiar with the functions of the display device and cannot make the display device display the corresponding functions, the seller can control the display device to display various functions. To this end, the display device 200 can be provided with a mall mode, which can also be called a demonstration mode, that is, a display mode in a mall environment.

[0109] In the demonstration mode, the display device 200 can be configured with a variety of demonstration functions, and can demonstrate the sound quality, picture quality and other functions of the display device by playing video images, etc., so that users can understand the product. Taking the demonstration of picture quality effect as an example, in the demonstration mode, the display device 200 can display the media screen using preset display parameters, and the display parameters may include contrast, brightness value, etc., to show the display effect of the display device 200 to the user.

[0110] When the display device 200 is in the demonstration mode, it can play pre-set media resources in a loop, such as high-resolution videos or pictures, and display product details, prices and other information of the display device 200 in combination with the electronic point of sale system (EPOS). The display device 200 can be divided into at least two areas in the display 260, wherein the first area is used to display the media screen of the video media resource, and the second area is used to display the EPOS screen, which is used to show the display parameters, device size or price and other information of the display device 200 to the user.

[0111] When demonstrating the sound quality effect, the display device 200 can play the audio content using the preset sound quality parameters. The display device 200 can play the audio through the built-in speakers of the device, or it can connect an external audio device and play the audio through the audio device. The display device 200 can also be provided with a joint sound function, that is, the audio is played through the local speakers and the external audio device at the same time. The user can set the device used by the display device 200 when playing audio.

[0112] In the shopping mall scenario, sellers can show users multiple display devices, and users can test the functions of each display device one by one and compare them to select the display device they need to buy. When demonstrating the sound quality effect, users may test the effect of the display device playing audio through the speaker and the effect of playing audio through the audio equipment to understand the performance of the display device. If the effect of different audio devices is tested through the same display device, the user's sensory impression of the playback effect of different audio devices will be reduced, and the user's comparison of the playback effect of different audio devices will not be very obvious. In addition, users may need to repeatedly switch the audio device of the same display device, which is cumbersome.

[0113] Therefore, users may have different presentation requirements for different display devices, for example, some display devices may need to play audio through local speakers, some display devices may need to play audio through audio, and some display devices may need to play audio through both local speakers and audio devices.

[0114] The user can switch the device that plays audio through the remote control of the display device. However, in the shopping mall scenario, the display devices displayed by the seller are only samples for demonstration functions. Considering the cost factor, multiple display devices may be controlled by one remote control, that is, the seller can control multiple display devices with one remote control. When the user instructs the display device to switch the audio device through the remote control, multiple display devices will respond to the remote control command, so that multiple display devices use the same type of device to play audio. For example, when the user uses the remote control to instruct the display device to play audio through the local speaker, within the signal range of the remote control, multiple display devices can receive the remote control command and set the audio device to the local speaker, but the user only wants a certain display device to use the local speaker, but does not change the audio device of other display devices. Multiple display devices respond to the remote control command at the same time, resulting in the user being unable to control the audio device of each display device individually, giving the user a poor user experience.

[0115] In some embodiments, a remote control can be provided for each display device so that each display device only responds to its corresponding remote control. However, in a shopping mall scenario, if each display device is equipped with a remote control, it is necessary to constantly switch the remote control when demonstrating each display device, which is cumbersome. In addition, for sellers, each display device is equipped with a remote control, which greatly increases the manufacturing cost. This method is not suitable for a store scenario.

[0116] In some embodiments, in order to control each display device individually, the user can use the physical buttons provided on the display device body to call out the setting interface to set the audio device. Figure 6 Schematic diagrams of setting interfaces in some embodiments are shown. Figure 6 As shown, the audio output device of the display device can be set through the setting interface, including the built-in speaker of the machine, the external audio device and the joint sound. Among them, the joint sound means that the display device uses the built-in speaker of the machine and the external audio device to play the sound of the display device at the same time.

[0117] It should be noted that for users who have purchasing needs, due to not understanding the display device, the user may not be able to directly call up the setting interface through the physical button. Even if the user knows the operation of calling up the setting interface, this operation is relatively cumbersome, giving the user a poor user experience.

[0118] In some embodiments, the display device can be connected to a specific audio control device through a device interface, and the audio control device is provided with a plurality of audio output buttons for setting the audio output device of the display device. The user can directly set the audio output device of the display device through the audio control device, and the display device can play sound using the audio output device set by the user. Since the display device and the audio control device are directly connected, the user can use the audio control device to separately control the audio device of the current display device, thereby improving the user experience.

[0119] Figure 7 A flowchart of the interaction between components of a display device in some embodiments is shown, including the following steps:

[0120] S701, in response to an audio playback instruction, detecting a current audio output device of a display device, and controlling the current audio output device to play audio data of the display device;

[0121] S702, in response to an audio output device setting instruction sent by the audio control device after the user triggers the audio output button, obtaining a target device corresponding to the audio output button triggered by the user; the target device is at least one of an audio device and an audio output device;

[0122] S703: Switch the current audio output device of the display device to the target device, and control the target device to play the audio data of the display device.

[0123] In some embodiments, the display device 200 can connect to an external device through the device interface 240, thereby establishing a connection with the external device and exchanging data. The display device 200 can send data to an external device, and the external device can be an audio device, such as a soundbar, headphones, etc. The display device 200 can send audio data to the audio device through the device interface 240 so that the audio device plays the sound of the display device. The display device 200 can also receive data sent by an external device. For example, the external device can be a set-top box, a media device, etc. The external device can send media data to the display device 200 through the device interface 240, and the display device 200 can play the media data.

[0124] The display device 200 and the external device are provided with data interfaces having the same interface specification and function. Figure 8 Schematic diagrams showing connections between display devices and external devices in some embodiments are shown. Figure 8As shown, the display device 200 and the external device may be provided with HDMI (High Definition Multimedia Interface). The user may plug the two ends of the HDMI interface data cable into the display device 200 and the external device respectively, thereby realizing data transmission between the display device 200 and the external device.

[0125] The display device 200 and the external device may also be connected in other ways, such as DVI (Digital Visual Interface), VGA (Video Graphics Array), USB (Universal Serial Bus), etc.; or may be connected in a wireless way, such as wireless LAN, Bluetooth connection, infrared connection, etc. The display device 200 may be provided with a plurality of device interfaces 240, each of which may be connected to an external device, so that the display device 200 can be connected to a plurality of external devices at the same time.

[0126] In some embodiments, after the display device 200 is turned on, the user can control the display device 200 to implement various functions, such as playing media resources.

[0127] In response to the audio play instruction, the controller 250 can detect the current audio output device of the display device 200 and control the current audio output device to play the audio data of the display device. The audio play instruction can be an instruction generated when the controller 250 detects that the display device 200 has a need to play sound.

[0128] During the process of the user controlling the display device 200, the display device 200 may have a need to play system sounds, for example, when the user moves the focus in the user interface through the remote control, the display device 200 may play a prompt sound of the focus moving, or when the user voice controls the display device 200, the display device 200 may play a prompt audio to reply to the user. In this regard, the controller 250 may generate an audio playback instruction.

[0129] The user can also control the display device 200 to play specific audio content. For example, in a shopping mall scenario, the user can instruct the display device 200 to play media, which can be separate audio content such as songs, or a video that needs to play picture and sound content. In response to the instruction to play the media, the display device 200 needs to play the audio data of the media, and the controller 250 can generate an audio playback instruction.

[0130] In some embodiments, the user can control the display device to enter a demonstration mode to display various demonstration functions. The display device 200 can have a built-in function configuration file, which can be stored in a JSON (JavaScript Object Notation) format.

[0131] The function configuration file may include the type of preset demonstration function (hereinafter referred to as: function category), the type and quantity of sub-items (hereinafter referred to as: demonstration items) contained in each function category. For example, the major categories of preset demonstration functions include but are not limited to: image (Picture) demonstration function, sound (Sound) demonstration function, connection (Connectivity) demonstration function, display device size (Sizes) demonstration function, system information (Systeminfo) demonstration function, etc.

[0132] In some embodiments, the image demonstration function may include at least one demonstration item, such as demonstration item A1, demonstration item A2, etc., and the demonstration item represents the image content. The display device 200 may configure a number of demonstration items according to the selling points and features of the image demonstration function, including but not limited to: detail enhancement, depth of field enhancement, 4K super resolution, MEMC (Motion Estimate and Motion Compensation), OSD PQ (On-Screen Display Picture Quality), zone light control, etc.

[0133] In some embodiments, the sound demonstration function may include at least one demonstration project, such as demonstration project B1, demonstration project B2, etc. The display device 200 may configure several demonstration projects according to the selling points and features of the sound demonstration function, including but not limited to: sound quality demonstration project, sound effect demonstration project, etc.

[0134] In some embodiments, the connection demonstration function may include at least one demonstration project, such as demonstration project C1, demonstration project C2, etc. The display device 200 may configure several demonstration projects according to the selling points and features of the connection demonstration function, including but not limited to: Bluetooth connection demonstration project, WIFI connection demonstration project, hotspot connection demonstration project, etc.

[0135] In some embodiments, the display device size demonstration function is used to demonstrate the image sizes of different screen sizes for users to compare, wherein the screen sizes include but are not limited to 55 inches, 50 inches, 43 inches, etc.

[0136] In some embodiments, the display device 200 can perform demonstrations based on the information attributes contained in the system information so that the user can understand the machine. The system information can include but is not limited to: device information (such as device name, model, etc.), operating system version, serial number, storage capacity, etc.

[0137] It should be noted that the preset demonstration functions and the types and quantities of demonstration items included in each preset demonstration function are not limited to the embodiments of the present application. The display device 200 can set a function configuration file according to the local functional characteristics and function demonstration requirements.

[0138] The controller 250 can run a first application, which is an application for implementing a functional demonstration of the display device 200. By running the first application, the controller 250 can call a functional configuration file, and obtain the category of the preset demonstration function from the functional configuration file, as well as the demonstration items included in each preset demonstration function. The controller 250 can run the first application, and according to the obtained functional configuration file, use the addView method of WindowManage to add a View page associated with the functional demonstration to the user interface, so that the functional demonstration-related pages can be displayed on top of other application pages.

[0139] In some embodiments, the user may input an instruction to the display device 200 to enter the demonstration mode, and in response to the instruction, the controller 250 may control the display 260 to display the demonstration function interface. Fig. 9 Schematic diagrams of demonstration function interfaces in some embodiments are shown. Fig. 9 As shown, the demonstration function interface 90 includes a function bar 91 and an item bar 92. The function bar 91 includes a plurality of function option controls, and the function option controls map a preset demonstration function in the function configuration file. The arrangement of the plurality of function option controls in the function bar 91 is not limited, for example, they can be arranged in rows. The user can control the focus to move in the function bar 91 by using the direction keys (e.g., left key, right key) of the control device 100 according to the function demonstration requirements, so that the selector selects the function option control corresponding to the target demonstration function.

[0140] The controller 250 can control the current audio output device to play the audio data of the display device. The current audio output device can be an audio output device (in the embodiment of the present application, the audio output device refers to the local speaker of the display device), an external audio device, or the audio output device and the audio device can sound at the same time.

[0141] In some embodiments, during the process of the display device 200 demonstrating the sound quality effect, the user can switch the audio output device of the display device 200 .

[0142] The display device 200 can be connected to the audio control device via the device interface 240. For example, the audio control device can be connected to the display device 200 through a USB interface. The audio control device is provided with a plurality of audio output buttons, which are used to set the audio output device of the display device.

[0143] The audio control device is a pre-built device for controlling the audio playback of the display device. For example, the audio control device can use a specific keyboard device. The keyboard is a device for inputting instructions and data for operating a computer device or a display device. It also refers to a set of function keys arranged by the system to operate a device. The keyboard can input specific information into the computer or display device 200, thereby issuing commands to the computer or display device 200, inputting data, etc. The keyboard is provided with a plurality of physical keys, each of which can represent a type of information or instruction.

[0144] When constructing an audio control device, multiple audio instructions required to control the display device 200 may be counted in advance, such as instructions for setting an audio output device, and each instruction may be bound to a physical button. Fig.10 Schematic diagrams of audio control devices in some embodiments are shown. Fig.10 As shown, the audio control device is provided with an audio output button and a volume control button. Among them, the audio output button is used to set the audio output device of the display device 200, including the display device 200 output button, the audio output button and the combined output button. The display device 200 output button is Fig.10 The "TV" button in is used to set the local speaker of the display device 200 as the audio output device. The audio output button is Fig.10 The "Sound" button in is used to set the sound device as the audio output device. The joint output button is Fig.10 The "Joint Sound" button is used to set the local speaker and audio device of the display device 200 as audio output devices at the same time.

[0145] The volume control button can be used to control the volume of the audio played by the display device 200. The volume control button includes a volume increase button, a volume decrease button, and a mute button. Fig.10 The "Volume +" button in the volume down button is Fig.10 The "Volume -" button in the Fig.10 ”Mute” button in the

[0146] The user can trigger various buttons of the audio control device to control the audio playing process of the display device 200.

[0147] In some embodiments, the user may trigger an audio output button to set the audio output device of the display device 200 .

[0148] In response to the audio output device setting instruction sent by the audio control device after the user triggers the audio output button, the controller 250 can obtain the target device corresponding to the audio output button triggered by the user. The target device is at least one of an audio device and an audio output device. The target device is the audio output device set by the user.

[0149] In some embodiments, after the user triggers a key of the audio control device, the audio control device will send a control instruction of the corresponding key to the display device 200. It should be noted that the keyboard device does not directly send the control content, but sends the content of the key itself (the system hardware code corresponding to the key) to the display device 200. Therefore, the control instruction sent by the audio control device is just a string of codes, and the controller 250 can convert the code into specific control content.

[0150] After configuring the audio control device, the technician can store the configuration file of the audio control device in the display device 200. The configuration file can be a keyboard layout table, which is used to characterize the keyboard layout and the key value of each key of the keyboard, and the control content input by the user using the keyboard can be identified according to the configuration file. Table 1 shows the content of the configuration file in some embodiments.

[0151] Table 1 Configuration file

[0152]

[0153] Among them, the key information is the control content.

[0154] "KEYCODE_VOLUME_MUTE" means mute;

[0155] "KEYCODE_VOLUME_UP" means increasing the volume;

[0156] "KEYCODE_VOLUME_DOWN" means to decrease the volume;

[0157] "KEYCODE_VOLUME_TV" means the speaker is sounding;

[0158] "KEYCODE_VOLUME_SOUNDBAR" indicates that the speaker is making sound;

[0159] "KEYCODE_VOLUME_HI_CONCERTON" indicates joint voicing.

[0160] The controller 250 can load the configuration file of the audio control device by calling the interface of the DirectFB library. Directfb (Direct Frame Buffer) is an open source project and a library on the GNU / Linux operating system. Directfb is a lightweight graphics library that provides hardware graphics acceleration, input device processing and abstraction. It integrates support for semi-transparent window systems and multi-layer displays on top of the LinuxFramebuffer driver. It is a layer that uses software to encapsulate graphics algorithms that current hardware cannot support to complete hardware acceleration. The DirectFB library can also process some device parameters. For example, in the embodiment of the present application, a configuration file can be loaded and key value information of buttons can be identified.

[0161] In some embodiments, taking the user triggering the audio output button as an example, the audio control device encodes the system hardware code of the audio output button triggered by the user to generate an audio output device setting instruction and sends it to the display device 200 .

[0162] In response to the audio output device setting instruction, the controller 250 may parse the audio output device setting instruction to obtain the system hardware code of the audio output button triggered by the user.

[0163] After acquiring the system hardware code, the controller 250 may load the configuration file of the audio control device. The controller 250 may convert the system hardware code into a key scan code Scan Code.

[0164] The configuration file includes the correspondence between the key scan code Scan Code and the key value KeyCode. Based on the configuration file, the controller 250 can obtain the key value KeyCode corresponding to the key scan code Scan Code.

[0165] The controller 250 can call the DirectFB library and use the DirectFB library to identify the key value corresponding to the key scan code. The DirectFB library can use the loaded configuration file to obtain the key value corresponding to the key scan code. In some embodiments, the controller 250 can also generate a key-value correspondence query model based on the configuration file, through which information query can be performed on the key-value correspondence. For example, a key scan code can be input into the key-value correspondence query model to obtain the key value corresponding to the key scan code.

[0166] The controller 250 can convert the key value of the button into the button information, so as to obtain the control content of the user. For example, the button information can include the target device corresponding to the audio output button. Among them, when the audio output button triggered by the user is the output button of the display device 200, the target device is the audio output device. When the audio output button triggered by the user is the audio output button, the target device is the audio device. When the audio output button triggered by the user is the combined output button, the target device is the audio output device and the audio device.

[0167] In some embodiments, the controller 250 may switch the current audio output device of the display device 200 to the target device, and control the target device to play the audio data of the display device 200 .

[0168] If the target device is an audio output device, the controller 250 can connect the audio output channel of the display device 200 to the audio output device and disconnect the audio output channel from the audio device. The controller 250 can send audio data of the display device 200 to the audio output device through the audio output channel.

[0169] If the target device is an audio device, the controller 250 can connect the audio output channel of the display device 200 to the audio device and disconnect the audio output channel from the audio output device. The controller 250 can send audio data of the display device 200 to the audio device through the audio output channel.

[0170] If the target device is an audio output device and an audio device, the controller 250 can connect the audio output channel of the display device 200 to the audio device and the audio output device at the same time. The controller 250 can send the audio data of the display device 200 to the audio device through the audio output channel, and send the audio data of the display device 200 to the audio output device through the audio output channel.

[0171] The controller 250 may control the target device to play the audio content of the display device 200 .

[0172] In some embodiments, after acquiring the target device corresponding to the audio output button triggered by the user, the controller 250 may detect the target device.

[0173] If the target device includes an audio device, the controller 250 may detect whether the display device 200 is currently connected to an available audio device to ensure normal playback of the sound.

[0174] The controller 250 may detect the device connection status of the device interface and determine whether the audio device is connected.

[0175] Based on detecting that an audio device is connected to the device interface, the controller 250 may switch the current audio output device of the display device 200 to the target device, and control the target device to play the audio content of the display device 200 .

[0176] Based on detecting that the device interface is not connected to the audio device, the controller 250 can first set the current audio output device of the display device 200 to the local speaker to ensure the normal playback of the sound of the display device 200. At the same time, the controller 250 can control the display to display a prompt message, which is used to prompt the audio device to be connected to the display device 200. Fig.11 Schematic diagrams showing prompt information in some embodiments. Fig.11 As shown, the prompt message may be “No audio device is currently detected, please connect the audio device.” When the device interface is detected to be connected to the audio device, the controller 250 switches the current audio output device of the display device 200 to the target device and controls the target device to play the audio content of the display device 200.

[0177] In some embodiments, the user can adjust the volume of the display device 200 through the volume control button of the audio control device.

[0178] In response to the volume control instruction sent by the audio control device after the user triggers the volume control button, the controller 250 can obtain the volume adjustment value corresponding to the volume control button. When the user triggers the volume increase button, the volume adjustment value can be "+1", and when the user triggers the volume decrease button, the volume adjustment value can be "-1".

[0179] The controller 250 may obtain the current volume of the current audio output device, and calculate the target volume according to the volume adjustment value and the current volume. The controller 250 may calculate the sum of the volume adjustment value and the current volume as the target volume.

[0180] The controller 250 may set the audio volume of the audio data currently played by the audio output device to be the target volume.

[0181] It should be noted that, when the user triggers the mute button, the controller 250 can directly adjust the volume of the display device 200 to 0 without calculating the volume adjustment value.

[0182] In some embodiments, the audio control device may be limited to control the display device 200 in the demonstration mode, and cannot control the display device 200 in other modes.

[0183] In response to the audio output device setting instruction sent by the audio control apparatus after the user triggers the audio output button, the controller 250 can obtain the current mode of the display device 200.

[0184] If the current mode of the display device 200 is the demonstration mode, the controller 250 may obtain the target device corresponding to the audio output button triggered by the user to switch and set the audio output device of the display device 200 .

[0185] If the current mode of the display device 200 is not the demonstration mode, the controller 250 does not switch the current audio output device of the display device 200 and controls the current audio output device to continue playing the audio data of the display device 200 .

[0186] In some embodiments, the control of the audio control device may not be restricted, that is, the audio control device can control the display device 200 in any mode of the display device 200, and the embodiments of the present application do not limit this.

[0187] In some embodiments, the display device 200 also supports an audio return channel (ARC) function and / or an enhanced audio return channel (eARC) function. The audio return channel can use sound return technology to return audio data to the power amplifier device for signal amplification processing and output to improve sound quality and other effects and improve user experience.

[0188] The audio return channel can be set in the device interface of the display device 200, for example, at a certain HDMI interface. When the HDMI interface is connected to an audio device, and the audio device also supports the audio return channel function, the display device 200 can set the audio output channel to the audio return channel. The display device 200 can enhance the audio data through the audio return channel function and send it to the audio device, so that the audio device plays high-quality audio data.

[0189] Fig.12 FIG. 2 shows a schematic diagram of hardware connection between an audio device and a display device 200 in some embodiments. Fig.12 As shown, the display device 200 and the audio device support the audio return channel function. The sound return is completed using the Utility signal line, while the interactive commands between the display device 200 and the audio device are completed through the CEC signal line. In this example, the transmission lines of audio data and command data are completely separated, and time-sharing control through software is not required. Among them, the transmission process of command data belongs to single-wire serial communication, which is called CEC protocol.

[0190] In some embodiments, in order to improve the sound effect of the audio played by the display device 200, the display device 200 can also automatically set the audio playback mode. The display device 200 can set the audio return channel to a certain device interface, and perform device access detection at the device interface. If the device interface is connected to an audio device, the display device 200 can set the audio output channel to the audio return channel and play the audio through the audio device to improve the sound quality. If there is no audio device connected to the device interface, the display device 200 can connect the audio output channel to the built-in speaker.

[0191] In some embodiments, the display device 200 may also automatically switch the device interface where the audio return channel is located.

[0192] After the display device 200 is powered on, the controller 250 may detect the connection status of the external device of the device interface.

[0193] Based on detecting that the target device interface is connected to an external device, the controller 250 may obtain the device type of the external device.

[0194] If the device type is an audio device, the controller 250 can set the audio return channel at the device interface, and the controller 250 can connect the audio output channel of the display device 200 to the target device interface to set the audio device as the current audio output device, thereby improving the sound quality effect through the audio return channel.

[0195] If the device type is not an audio device, the controller 250 may set the audio output device as the current audio output device.

[0196] The embodiment of the present application also provides an audio output device switching method, which is applied to a display device, and the method includes:

[0197] Step 701: In response to an audio playback instruction, detect a current audio output device of a display device, and control the current audio output device to play audio data of the display device;

[0198] Step 702: in response to the audio output device setting instruction sent by the audio control device after the user triggers the audio output button, obtain the target device corresponding to the audio output button triggered by the user; the target device is at least one of the audio device and the audio output device;

[0199] Step 703: Switch the current audio output device of the display device to the target device, and control the target device to play the audio data of the display device.

[0200] The same and similar parts between the various embodiments in this specification can be referenced to each other and will not be described again here.

[0201] Those skilled in the art can clearly understand that the technology in the embodiments of the present invention can be implemented by means of software plus a necessary general hardware platform. Based on this understanding, the technical solution in the embodiments of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which can be stored in a storage medium such as ROM / RAM, a disk, an optical disk, etc., and includes a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods of various embodiments of the present invention or certain parts of the embodiments.
