[0052] In some embodiments, the user input interface 280 can be used to receive instructions from user input.

[0053] Figure 3 For some embodiments of the present application Figure 1 The hardware configuration block diagram of the control device in. As Figure 3 shown, the control device 100 may include: a controller 110, a communication interface 130, a user input / output interface, a memory, and a power supply.

[0054] The control device 100 is configured to control the display device 200, and can receive input operation instructions from the user, and convert the operation instructions into instructions recognizable and responsive by the display device 200, playing the role of an interaction intermediary between the user and the display device 200.

[0055] In some embodiments, the control device 100 may be an intelligent device. For example: the control device 100 can install various applications for controlling the display device 200 according to user needs.

[0056] In some embodiments, as Figure 1 shown, the mobile terminal 300 or other intelligent electronic devices, after installing the application for controlling the display device 200, can perform functions similar to those of the control device 100.

[0057] The controller 110 includes a processor 112, a RAM 113, a ROM 114, a communication interface 130, and a communication bus. The controller 110 is used to control the operation and operation of the control device 100, as well as the communication and cooperation between internal components and the data processing functions between the external and internal.

[0058] Under the control of the controller 110, the communication interface 130 realizes the communication of control signals and data signals with the display device 200. The communication interface 130 may include at least one of a WiFi chip 131, a Bluetooth module 132, an NFC module 133, and other short-range communication modules.

[0059] The user input / output interface 140, where the input interface includes at least one of a microphone 141, a touchpad 142, a sensor 143, a button 144, and other input interfaces.

[0060] In some embodiments, the control device 100 includes at least one of the communication interface 130 and the input / output interface 140. The communication interface 130 configured in the control device 100, such as WiFi, Bluetooth, NFC, etc. modules, can encode the user input instructions through the WiFi protocol, or the Bluetooth protocol, or the NFC protocol, and send them to the display device 200.

[0061] The memory 190 is used to store various operating programs, data, and applications for driving and controlling the control device 100 under the control of the controller. The memory 190 can store various control signal instructions input by the user.

[0062] The power supply 180 is used to provide operating power support for each component of the control device 100 under the control of the controller.

[0063] To facilitate user interaction, in some embodiments, the display device 200 may run an operating system. The operating system is a computer program used to manage and control the hardware and software resources of the display device 200. The operating system may provide a user interface (to control the display device), allow the user to interact with the display device 200, and support the running of various application programs.

[0064] 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.

[0065] The operating system can be divided into different modules or layers according to the functions implemented, e.g. Figure 4 As shown, in some embodiments, the system is divided into four layers, from top to bottom: the application layer (abbreviated as "application layer"), the application framework layer (abbreviated as "framework layer"), the system library layer and the kernel layer.

[0066] In some embodiments, the application layer provides services and interfaces for applications, enabling the display device 200 to run applications and interact with the user based on these applications. The application layer can host at least one application, which can include built-in window programs, system settings programs, clock programs, and other applications 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 examples above.

[0067] The framework layer provides applications with an application programming interface (API) and programming framework. The application framework layer includes predefined functions. The application framework layer acts as a processing center, determining the actions taken by applications in the application layer. Through the API, applications can access system resources and services during execution.

[0068] like Figure 4As shown in the figure, in the embodiment of the present application, the application framework layer includes a view system (View System), managers, content providers, etc. Among them, the view system can design and implement the interface and interaction of the application. The view system includes lists, grids, text boxes, buttons, etc. The managers include at least one of the following modules: The Activity Manager is used to interact with all the activities running in the system; the Location Manager is used to provide access to the system location service for system services or applications; the Package Manager is used to retrieve various information related to the application packages currently installed on the device; the Notification Manager is used to control the display and clearing of notification messages; the Window Manager is used to manage icons, windows, toolbars, wallpapers, and desktop widgets on the user interface.

[0069] In some embodiments, the Activity Manager is used to manage the life cycles of various applications and the usual navigation back function, such as controlling the exit, opening, and backward movement 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, taking screenshots, and controlling the change of the display window. For example, shrinking the display window, jittering the display, and distorting the display.

[0070] In some embodiments, the system runtime library layer can provide support for the framework layer. When the framework layer is used, the operating system will run the instruction library contained in the system runtime library layer, such as the C / C++ instruction library, to implement the functions that the framework layer needs to achieve.

[0071] In some embodiments, the kernel layer is a functional layer between the hardware and software of the display device 200. The kernel layer can implement functions such as hardware abstraction, multitasking, and memory management. For example, as Figure 4 shown, hardware drivers can be configured in the kernel layer. The drivers included in the kernel layer can be at least one of the following drivers: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor drivers (such as fingerprint sensors, temperature sensors, pressure sensors, etc.), and power drivers, etc.

[0072] It should be noted that the above examples are only simple divisions of the functions of the operating system, and do not limit the specific form of the operating system of the display device 200 in the embodiments of the present application. Depending on factors such as the functions of the display device and the type of the operating system, the number of levels and the specific level types included in the operating system may be in other forms.

[0073] In some embodiments, the display device includes: a display configured to display content from a broadcast system or a network and / or a user interface; at least one sound channel, each sound channel being used to play corresponding audio; and at least one processor connected to the display and the at least one sound channel and configured to execute instructions to enable the display device to perform the following steps, see Figure 5 as shown:

[0074] Step 501, in response to an open instruction for a target page, display the target page through the display, obtain multimedia data corresponding to the target page, play the multimedia data on the target page; obtain sound channel capability data of the display device, and display at least one sound channel control option matching the sound channel capability data on the target page.

[0075] Optionally, an application program (Application, abbreviated as APP) for implementing the sound channel display method provided in the embodiments of the present application is installed on the display device, and the APP can be used to open a target page. After the user starts the APP, the APP will display the target page.

[0076] Specifically, the user can perform a start operation on the APP, for example, click on the icon of the APP. In response to the start operation, the display device can generate an open instruction for the target page and send the start instruction to the APP, and the APP will display the target page through the display.

[0077] Optionally, in response to an open instruction for a target page, on the one hand, the multimedia data corresponding to the target page can be obtained from a local or remote server. The multimedia data can be audio data or audio-visual data, which is related to the settings in the development process of the target page. After obtaining the multimedia data corresponding to the target page, the multimedia data can be played on the target page. On the other hand, the sound channel capability data of the display device can be obtained, and at least one sound channel control option matching the sound channel capability data is displayed on the target page.

[0078] Among them, the audio-visual data includes audio data and video data. The audio data in the embodiments of the present application includes audio of multiple sound channels. When playing the audio data, the audio of a certain sound channel is played on the corresponding sound channel. For example, the audio of the woofer speaker is played on the woofer speaker.

[0079] It should be noted that the process of obtaining the multimedia data and playing the multimedia data on the target page, and the process of obtaining the channel capability data and displaying the channel control options on the target page can be executed in parallel or sequentially. The embodiments of the present application do not make any limitations on this.

[0080] Optionally, the channel capability data of the display device is stored in the hardware, and the channel capability data of the display device can be read from the hardware. The channel capability data can be data used to characterize the channel configuration of the display device. Exemplarily, the channel capability data can be 4.1, 5.1, 5.1.2, etc. Among them, 5.1.2 means that the display device includes two side speakers, two center speakers, two screen speakers, one subwoofer speaker, and two main speakers.

[0081] Optionally, a channel mapping table is stored in the display device. The channel mapping table includes the channel control options supported by different channel capability data. After obtaining the channel capability data, the channel control options supported by the channel capability data can be found from the channel mapping table, and the found channel control options are used as the channel control options matching the channel capability data. The found channel control options may be one or more than one.

[0082] Optionally, after obtaining at least one channel control option matching the channel capability data, the at least one channel control option can be rendered and displayed on the target page.

[0083] Exemplarily, assume that the channel capability data is 5.1.2, and the channel control options supported by 5.1.2 in the channel mapping table include: Conventional Sound, 3D Sound on, Subwoofer off, and Surround Sound off, a total of four options. These four options can be rendered and displayed on the target page. It should be noted that after obtaining the multimedia data corresponding to the target page, the corresponding audio in the multimedia data can be played using the default channel. For example, if the default channel is all channels, then after obtaining the multimedia data corresponding to the target page, the corresponding audio in the multimedia data is played using all channels. At this time, when rendering at least one channel control option, the option corresponding to the default channel can be rendered as the selected state, as Figure 6 shown.

[0084] Step 502: In response to a triggering operation on the first channel control option among at least one channel control option, identify the channel that needs to emit sound associated with the first channel control option as the first channel; control the first channel to play the corresponding audio in the multimedia data, and display an animation at the visual position corresponding to the first channel on the target page.

[0085] Optionally, for at least one channel control option presented on the target page, the user can select any one of the control options, that is, the user can perform a triggering operation on any one of the control options. Assume that the user performs a triggering operation on the first channel control option. In response to this triggering operation, the channel that needs to emit sound associated with the first channel control option can be identified as the first channel.

[0086] Among them, each channel control option is associated with a channel that needs to emit sound and a channel that does not need to emit sound. Optionally, the display device stores the channels that need to emit sound and the channels that do not need to emit sound associated with each channel control option. In response to the user's triggering operation on the first channel control option, the display device can find the channel that needs to emit sound associated with the first channel control option as the first channel.

[0087] Exemplarily, the channel capability data is 5.1.2, and at least one channel control option includes: Conventional Sound, 3D Sound on, Subwoofer off, and Surround Sound off, a total of four options. Among them, the channels that need to emit sound associated with Conventional Sound are: two main speakers, and the channels that do not need to emit sound associated with Conventional Sound are: two side speakers, two center speakers, two screen speakers, and one woofer speaker. The channels that need to emit sound associated with 3D Sound on are: all channels (i.e., two side speakers, two center speakers, two screen speakers, one woofer speaker, and two main speakers). Correspondingly, the channels that do not need to emit sound associated with 3D Sound on are: none. The channels that need to emit sound associated with Subwoofer off are: two side speakers, two center speakers, two screen speakers, and two main speakers; the channels that do not need to emit sound associated with Subwoofer off are: one woofer speaker. The channels that need to emit sound associated with Surround Sound off are: two center speakers, two screen speakers, one woofer speaker, and two main speakers, and the channels that do not need to emit sound associated with Surround Sound off are: two side speakers.

[0088] It should be noted that: In this application, the naming of the four options of Conventional Sound, 3D Sound on, Subwoofer off, and Surround Sound off, the channels that need to produce sound associated with each option, and the channels that do not need to produce sound are merely examples. The four options can also have other names, and the channels that need to produce sound and the channels that do not need to produce sound associated with them can be adapted to the naming of the options. Exemplarily, the four options can be: Conventional Sound, 3D Sound, Subwoofer, and Surround Sound.

[0089] Among them, after identifying the channel that needs to produce sound (i.e., the first channel) associated with the first channel control option, the first channel can be controlled to be turned on so that the first channel plays the corresponding audio in the multimedia data.

[0090] Among them, for each channel on the display device, its projection on the screen can be obtained, and the position where the projection is located is used as the visual position of the channel. After identifying the channel that needs to produce sound (i.e., the first channel) associated with the first channel control option, an animation can be displayed at the visual position corresponding to the first channel on the target page. Exemplarily, in the case where the channel capability data is 4.1, an example of the target page when the user selects 3D Sound on is Figure 7 as shown, and animations are displayed at the visual positions corresponding to all channels.

[0091] Optionally, the animation displayed at the visual position corresponding to the first channel can be a pre-set sound wave animation.

[0092] Step 503: In response to the operation of switching from the first channel control option to the second channel control option among at least one channel control option, identify the channel that needs to produce sound associated with the second channel control option as the second channel; switch from the first channel to the second channel to play the corresponding audio in the multimedia data, and display an animation at the visual position corresponding to the second channel on the target page.

[0093] Among them, when the user selects the second channel control option after selecting the first channel control option, it is considered that the user has performed the operation of switching from the first channel control option to the second channel control option. In response to this operation, the display device identifies the channel that needs to produce sound associated with the second channel control option as the second channel.

[0094] As described above, each channel control option is associated with channels that need to emit sound and channels that do not need to emit sound. Optionally, the display device stores the channels that need to emit sound and the channels that do not need to emit sound associated with each channel control option. In response to an operation of switching from the first channel control option to the second channel control option, the display device can find the channel that needs to emit sound associated with the second channel control option as the second channel.

[0095] Among them, after identifying the channel that needs to emit sound (i.e., the second channel) associated with the second channel control option, the first channel can be controlled to close and the second channel can be controlled to open, so that the second channel plays the corresponding audio in the multimedia data. Thus, the playback of the corresponding audio in the multimedia data is switched from the first channel to the second channel.

[0096] As described above, for each channel on the display device, its projection on the screen can be obtained, and the position where the projection is located is used as the visual position of the channel. After identifying the channel that needs to emit sound (i.e., the second channel) associated with the second channel control option, an animation can be displayed at the visual position corresponding to the second channel on the target page.

[0097] Optionally, the animation displayed at the visual position corresponding to the second channel can be a pre-set sound wave animation.

[0098] In the above embodiments, in response to an open instruction for the target page, the target page can be displayed through the display. On the one hand, the multimedia data corresponding to the target page is obtained, and the multimedia data is played on the target page. On the other hand, the channel capability data of the display device is obtained, and at least one channel control option matching the channel capability data is displayed on the target page; so that the user can intuitively see which channel control options the display device supports. In response to a trigger operation for the first channel control option among at least one channel control option, the channel that needs to emit sound associated with the first channel control option is identified as the first channel; the first channel is controlled to play the corresponding audio in the multimedia data, and an animation is displayed at the visual position corresponding to the first channel on the target page; so that the user can intuitively see which channels are emitting sound under this option after selecting the first channel control option. In response to an operation of switching from the first channel control option to the second channel control option among at least one channel control option, the channel that needs to emit sound associated with the second channel control option is identified as the second channel; the playback of the corresponding audio in the multimedia data is switched from the first channel to the second channel, and an animation is displayed at the visual position corresponding to the second channel on the target page; so that the user can intuitively see which channels are emitting sound under the second channel control option when switching from the first channel control option to the second channel control option. This way of converting the channel spatial distribution into visual elements greatly enhances the user's multi-modal perception.

[0099] In some embodiments, the processor is further configured to: in response to a triggering operation for a first channel control option among the at least one channel control option, identify a channel that does not need to emit sound associated with the first channel control option as a third channel; control the third channel to be turned off, and at a visual position corresponding to the third channel on the target page, display a dimmed channel icon and hide the animation.

[0100] As described above, the display device stores channels that need to emit sound and channels that do not need to emit sound associated with each channel control option. In response to a triggering operation for a first channel control option among the at least one channel control option, the display device can find the channel that needs to emit sound associated with the first channel control option as a first channel; find the channel that does not need to emit sound associated with the first channel control option as a third channel.

[0101] Among them, after the display device identifies the first channel and the third channel, it can control the first channel to be turned on and the third channel to be turned off, so that only the first channel plays the corresponding audio in the multimedia data. The purpose of controlling the channel switch through the channel control option is achieved.

[0102] As described above, for each channel on the display device, its projection on the screen can be obtained, and the position where the projection is located is used as the visual position of the channel. For each channel, the channel icon of the channel can be displayed at the visual position corresponding to the channel on the target page.

[0103] Among them, after identifying the channel that needs to emit sound (i.e., the first channel) associated with the first channel control option and the channel that does not need to emit sound (the third channel) associated with the first channel control option, the channel icon of the first channel on the target page can be highlighted, and a sound wave animation emitting from the channel icon can be displayed; the channel icon of the third channel on the target page can be dimmed, and the sound wave animation emitting from the icon can be hidden.

If it needs to emit sound, display a sound wave animation at its corresponding visual position; if it does not need to emit sound, dim its channel icon and hide the sound wave animation.

[0105] In the above embodiments, in response to a triggering operation for a first channel control option among at least one channel control option, the channels that need to emit sound associated with the first channel control option are identified as the first channels; and the channels that do not need to emit sound associated with the first channel control option are identified as the third channels; the first channels are controlled to play the corresponding audio in the multimedia data, and the third channels are controlled to be closed; the purpose of controlling the channel switch through the channel control option is achieved. An animation is displayed at the visual position corresponding to the first channel on the target page; at the visual position corresponding to the third channel on the target page, a grayed-out channel icon is displayed and the animation is hidden, so that after the user selects the first channel control option, they can intuitively see which channels are emitting sound under this option. This way of converting the channel spatial distribution into visible elements greatly enhances the user's multimodal perception.

[0106] In some embodiments, the processor is further configured to: in response to an operation of closing a target channel triggered by a setting option, display a target page; obtain the multimedia data corresponding to the target page, and play the multimedia data on the target page; control the other channels except the target channel to play the corresponding audio in the multimedia data; display an animation at the visual positions corresponding to the other channels on the target page; at the visual position corresponding to the target channel on the target page, display a grayed-out channel icon and hide the animation.

[0107] Among them, the setting option includes an option for controlling the switch of the target channel. The target channel includes a subwoofer channel, a surround sound channel, etc. After the user performs a triggering operation to close the target channel through this option, in response to this operation, the display device can pull up and display the target page, obtain the multimedia data corresponding to the target page, and play the multimedia data on the target page.

[0108] Among them, in response to the above operation, the display device can control the target channel to be closed, control the other channels except the target channel to be opened, so that the other channels play the corresponding audio in the multimedia data, achieving the purpose of controlling the channel switch through the setting option. In addition, in response to the above operation, the display device can highlight the channel icons of the other channels on the target page and display a sound wave animation emitting from the channel icons; the channel icon of the target channel on the target page can be grayed out and the sound wave animation emitting from the icon can be hidden.

[0109] Exemplarily, after the user performs a triggering operation to close the subwoofer channel, an example of the target page is as Figure 9 shown, the channel icon of the subwoofer channel is grayed out and the animation is hidden, and the channel icons of the other channels are highlighted and a sound wave animation emitting from the channel icons is displayed.

[0110] Exemplarily, after the user performs a triggering operation to close the surround sound channel, an example of the target page is as Figure 10As shown, the channel icons of the surround sound channels are grayed out and the animations are hidden, while the channel icons of the other channels are highlighted and sound wave animations emitting from the channel icons are displayed.

[0111] Exemplarily, after the user performs a trigger operation to turn off the subwoofer channel and the surround sound channel, an example of the target page is as Figure 11 As shown, the channel icons of the subwoofer channel and the surround sound channel are grayed out and the animations are hidden, while the channel icons of the other channels are highlighted and sound wave animations emitting from the channel icons are displayed.

[0112] In the above embodiments, in response to an operation to turn off the target channel triggered by setting options, a target page is displayed; the multimedia data corresponding to the target page is obtained, and the multimedia data is played on the target page; the other channels except the target channel are controlled to play the corresponding audio in the multimedia data; the purpose of controlling the channel switch through the setting options is achieved. Animations are displayed at the visual positions corresponding to the other channels on the target page; at the visual position corresponding to the target channel on the target page, a grayed-out channel icon is displayed and the animation is hidden; so that after the user turns off the target channel through the setting options, the user can intuitively see which channels are still emitting sound, improving the user's visual perception of the channels.

[0113] In some embodiments, the setting options include one or more of at least one channel control option; the processor is further configured to:

[0114] In response to a trigger operation for the target channel control option in the setting options, display the target page, obtain the multimedia data corresponding to the target page, and play the multimedia data on the target page; identify the channels that need to emit sound associated with the target channel control option as the fourth channels; control the fourth channels to play the corresponding audio in the multimedia data and display animations at the visual positions corresponding to the fourth channels on the target page.

[0115] Optionally, the channels that do not need to emit sound associated with the target channel control option can also be identified as the fifth channels; control the fifth channels to be turned off, and at the visual positions corresponding to the fifth channels on the target page, display grayed-out channel icons and hide the animations.

[0116] Among them, one or more of the at least one channel control option mentioned in the above embodiments can be integrated into the setting options, and which channel control options are integrated into the setting options can be flexibly selected based on the actual situation, and the embodiments of the present application do not make limitations.

[0117] Among them, the user can control the on / off of the sound channels through the sound channel control options included in the setting options. Specifically, the user can perform a trigger operation on the target sound channel control option in the setting options. In response to this trigger operation, the display device can pull up and display the target page, obtain the multimedia data corresponding to the target page, and play the multimedia data on the target page.

[0118] Among them, in response to the above trigger operation, the display device can identify the sound channel that needs to emit sound associated with the target sound channel control option as the fourth sound channel; and can control the fourth sound channel to be turned on so that the fourth sound channel plays the corresponding audio in the multimedia data. Thus, the purpose of controlling the sound channel switch through the sound channel control option included in the setting option is achieved.

[0119] Among them, in response to the above trigger operation, the display device can also identify the sound channel that does not need to emit sound associated with the target sound channel control option as the fifth sound channel; and while controlling the fourth sound channel to be turned on, control the fifth sound channel to be turned off, so as to achieve playing the corresponding audio in the multimedia data by the fourth sound channel.

[0120] Among them, after the display device identifies the sound channel that needs to emit sound (i.e., the fourth sound channel) and the sound channel that does not need to emit sound (the fifth sound channel) associated with the target sound channel control option, it can highlight the sound channel icon of the fourth sound channel on the target page and display a sound wave animation emitting from the sound channel icon; and can gray out the sound channel icon of the fifth sound channel on the target page and hide the sound wave animation emitting from the icon.

[0121] In the above embodiments, there are various sound wave control options included in the setting options. The user can perform a trigger operation on a certain sound wave control option. In response to this trigger operation, the display device will pull up the target page, highlight the sound channel icon corresponding to the sound channel that needs to emit sound on the target page, and display a sound wave animation emitting from the sound channel icon, so that after the user triggers a certain sound wave control option, it can be intuitively seen which remaining sound channels are emitting sound under this sound wave control option, improving the user's visual perception of the sound channels.

[0122] In some embodiments, when the processor executes to display an animation at the visual position corresponding to the first sound channel on the target page, it is further configured to: display a highlighted sound channel icon at the visual position corresponding to the first sound channel on the target page; and obtain the amplitude information of the audio corresponding to the first sound channel in the multimedia data, and display a sound wave animation synchronously mapped with the amplitude information at the visual position corresponding to the first sound channel.

[0123] As described above, for each sound channel on the display device, its projection on the screen can be obtained, and the position where the projection is located is used as the visual position of the sound channel. For each sound channel, the sound channel icon of the sound channel can be displayed at the visual position corresponding to the sound channel on the target page.

[0124] Among them, after identifying the channel that needs to sound associated with the first channel control option (i.e., the first channel), the channel icon of the first channel on the target page can be highlighted. And, extract the audio corresponding to the first channel from the multimedia data, and obtain the amplitude information of the audio, and display a sound wave animation synchronously mapped with the above amplitude information near the highlighted channel icon.

[0125] Optionally, the sound wave animation synchronously mapped with the amplitude information can emanate from the highlighted channel icon.

[0126] In some embodiments, refer to Figure 12 As shown, first obtain the channel capability data of the display device, display at least one channel control option that matches the channel capability data, control the channel to sound based on the user's selection, for a certain channel, determine whether it needs to sound, if it needs to sound, highlight the corresponding channel icon, obtain the audio corresponding to the channel, and obtain the amplitude information of the audio, and display a sound wave animation synchronously mapped with the amplitude information; if it does not need to sound, gray out the channel icon and hide the sound wave animation.

[0127] In the above embodiments, display the highlighted channel icon at the visual position corresponding to the first channel on the target page; and obtain the amplitude information of the audio corresponding to the first channel in the multimedia data, and display a sound wave animation synchronously mapped with the amplitude information at the visual position corresponding to the first channel, so that the visual sound wave is synchronously mapped with the audio amplitude, enhancing the visual and auditory correlation and improving the multi-modal perception.

[0128] In some embodiments, a channel display method is provided, which can be applied to a display device. The display device includes an application program, a middleware layer, an audio driver, and hardware. The hardware includes at least one channel. The channels in the embodiments of the present application can also be referred to as speakers, sound-emitting devices, etc. The channel display method includes the following steps:

[0129] Step A: The application program responds to an open instruction for the target page, displays the target page through the display, obtains the multimedia data corresponding to the target page, and plays the multimedia data on the target page.

[0130] Among them, the application program here can be the application program (Application, abbreviated as APP) mentioned in the above embodiments for implementing the channel display method provided by the embodiments of the present application. The APP can be used to open the target page. After the user starts the APP, the APP will display the target page. The user can perform a start operation on the APP, for example, click the icon of the APP. In response to the start operation, the display device can generate an open instruction for the target page and send the start instruction to the APP. In response to the start instruction, the APP displays the target page through the display.

[0131] Among them, the application can obtain the multimedia data corresponding to the target page from a local or remote server and play the multimedia data on the target page. For the detailed implementation, refer to the above, and the embodiments of this application will not be elaborated herein.

[0132] Refer to Figure 13 As shown, the channel display method provided by the embodiments of this application includes a user starting a channel control process and a user selecting a channel control process. This step can be the first step in the user starting the channel control process, that is Figure 13 1. In response to an open instruction for the target page, display the target page.

[0133] Step B: The application obtains the channel capability data of the display device from the hardware through the middleware layer and the audio driver, and displays at least one channel control option matching the channel capability data on the target page.

[0134] Among them, in response to an open instruction for the target page, the application can also obtain the channel capability data of the display device from the hardware. Refer to Figure 13 As shown, the process for the application to obtain the channel capability data of the display device from the hardware may include: 2. The application sends a request to the middleware layer to obtain the channels supported by the current model; 3. After receiving the above request, the middleware layer sends a request to the audio driver to read the hardware channel capabilities; 4. After receiving the above request, the audio driver sends a request to read the register / chip configuration to the hardware through the Inter-Integrated Circuit (I²C) or Serial Peripheral Interface (SPI); 5. After receiving the above request, the hardware returns the channel capability data to the audio driver; Exemplarily, the channel capability data is, for example, 4.1, 5.1, or 5.1.2, etc.; 6. The audio driver further returns the channel capability data to the middleware layer; 7. The middleware layer further returns the channel capability data to the application; 8. After receiving the channel capability data, the application obtains the channel control options matching the channel capability data and renders and displays the at least one channel control option on the target page.

[0135] Among them, the Inter-Integrated Circuit (I²C) and Serial Peripheral Interface (SPI) are two widely used synchronous serial communication protocols. The channel capability data is generally stored in the register configuration or chip configuration. Therefore, the audio driver can send a request to read the register / chip configuration to the hardware to obtain the channel capability data.

[0136] Step C: The application receives a trigger operation for the first channel control option among at least one channel control option, and sends the first channel mode corresponding to the first channel control option to the middleware layer; the middleware layer sends a first channel configuration instruction carrying at least the first channel mode to the audio driver; the audio driver, based on the first channel mode carried in the first channel configuration instruction, identifies the channel that needs to emit sound associated with the first channel control option as the first channel, and performs sound output configuration on the first channel; the first channel switches to the channel output mode to play the corresponding audio in the multimedia data; the hardware returns a first control success result to the application through the audio driver and the middleware layer, and the first control success result carries the current state of the first channel. After receiving the first control success result, the application displays an animation at the visual position corresponding to the first channel on the target page.

[0137] This step is for the user to select the channel control process. For at least one channel control option displayed on the target page, the user can select any one of the control options, that is, the user can perform a trigger operation on any one of the control options. See Figure 13 As shown, the user's selection of the channel control process may include: 9. The user selects the first channel control option, and the application sends the first channel mode corresponding to the first channel control option to the middleware layer; 10. After receiving the first channel mode, the middleware layer generates a first channel configuration instruction based on parameters such as the first channel mode and gain, and sends the first channel configuration instruction to the audio driver; 11. After receiving the first channel configuration instruction, the audio driver, based on the first channel mode carried in the first channel configuration instruction, identifies the channel that needs to emit sound associated with the first channel control option as the first channel, and identifies the channel that does not need to emit sound associated with the first channel control option as the third channel, and configures the registers of the first channel and the registers of the third channel; 12. The first channel switches to the channel output mode based on the configuration, and the third channel switches to the closed mode based on the configuration, so as to realize playing the corresponding audio in the multimedia data by the first channel; 13. The hardware sends an interrupt signal or a status register update signal to the audio driver; 14. The audio driver reads the updated content of the status register to confirm the configuration result; 15. The hardware returns a first control success result to the audio driver; 16. The audio driver further returns the first control success result to the middleware layer; 17. The middleware layer further returns the first control success result to the application. 18. The application displays an animation at the visual position corresponding to the first channel on the target page; 19. At the visual position corresponding to the third channel on the target page, a grayed-out channel icon is displayed and the animation is hidden.

[0138] Among them, gain is a technical parameter that controls how many times the sound is amplified. Turning it up makes the sound louder, and turning it down makes the sound softer. That is, gain is a parameter that technically controls the volume. The parameter value of gain can be calculated for the current overall machine volume through a calculation formula: Gain (dB) = Minimum gain + 10 × log10 (Volume percentage / 100).

[0139] Among them, the audio driver can control the channel switch through channel mapping. For example, the integrated circuit has an internal audio bus (Inter-IC Sound, abbreviated as I²S) channel mapping. The core task of I²S is to accurately transmit audio data to the hardware in the order of channels. The implementation of channel mapping is to configure the register to clarify the positions and alignment methods of the left and right channels in the data frame, so that the hardware knows which section of data should be sent to the corresponding speaker.

[0140] Among them, each channel control option corresponds to a channel mode, and each channel control option is associated with channels that need to produce sound and channels that do not need to produce sound. The display device stores this corresponding relationship and association relationship. After receiving the first channel configuration instruction, the audio driver can determine the channels that need to produce sound associated with the first channel control option based on this corresponding relationship and association relationship.

[0141] Step D: The application receives the operation of switching from the first channel control option to the second channel control option among at least one channel control option, and sends the second channel mode corresponding to the second channel control option to the middleware layer; the middleware layer sends a second channel configuration instruction carrying at least the second channel mode to the audio driver; the audio driver identifies the channels that need to produce sound associated with the second channel control option based on the second channel mode carried in the second channel configuration instruction as the second channel, and performs sound output configuration on the second channel; the second channel switches to the channel output mode to play the corresponding audio in the multimedia data; the hardware returns a second control success result to the application through the audio driver and the middleware layer, and the second control success result carries the current state of the second channel; after receiving the second control success result, the application displays an animation at the visual position corresponding to the second channel on the target page.

[0142] This step is the implementation process when the user selects the second channel control option after selecting the first channel control option, that is, the internal response process after switching from the first channel control option to the second channel control option. After the user selects the second channel control option, the internal processing process of the display device is similar to that of the first channel control option introduced above, and this application embodiment will not elaborate here.

[0143] In the above embodiments, a channel display method is provided, which is applied to a display device. The display device includes an application, a middleware layer, an audio driver, and hardware. The hardware includes at least one channel. Through the interaction of these modules, when a user selects a certain channel control option, the channels that need to emit sound associated with the channel control option will not only emit sound, but also an animation will be presented at the corresponding visual position on the target page. So that after the user selects the first channel control option, it is possible to intuitively see which channels are emitting sound under this option, greatly enhancing the user's multi-modal perception.

[0144] In some embodiments, the channel display method provided by the embodiments of the present application further includes: The audio driver identifies the channels that do not need to emit sound associated with the first channel control option, based on the first channel mode carried in the first channel configuration instruction, as the third channel, and configures the third channel to be closed; The third channel switches to the closed output mode; The hardware returns a first control success result to the application through the audio driver and the middleware layer. The first control success result carries the current state of the third channel; After receiving the first control success result, the application displays a grayed-out channel icon and hides the animation at the visual position corresponding to the third channel on the target page.

[0145] Specifically, after receiving the first channel configuration instruction, the audio driver can identify the channels that need to emit sound (i.e., the first channel) and the channels that do not need to emit sound (i.e., the third channel) associated with the first channel control option, based on the first channel mode carried in the first channel configuration instruction. The first channel can be controlled to switch to the channel output mode, and the third channel can be controlled to switch to the closed output mode by configuring the register. After the hardware completes the switch, it can return a first control success result to the application through the audio driver and the middleware layer. The first control success result carries the current state of the first channel and the current state of the third channel. After receiving the first control success result, the application displays an animation at the visual position corresponding to the first channel on the target page; At the visual position corresponding to the third channel on the target page, a grayed-out channel icon is displayed and the animation is hidden.

[0146] In the above embodiments, an animation is displayed at the visual position corresponding to the first channel on the target page; At the visual position corresponding to the third channel on the target page, a grayed-out channel icon is displayed and the animation is hidden, so that after the user selects the first channel control option, it is possible to intuitively see which channels are emitting sound under this option. This way of converting the channel spatial distribution into visible elements greatly enhances the user's multi-modal perception.

[0147] In some embodiments, displaying an animation at the visual position corresponding to the first sound channel on the target page includes: displaying a highlighted sound channel icon at the visual position corresponding to the first sound channel on the target page; and obtaining the amplitude information of the audio corresponding to the first sound channel in the multimedia data, and displaying a sound wave animation synchronously mapped with the amplitude information at the visual position corresponding to the first sound channel.

[0148] As described above, for each sound channel on the display device, its projection on the screen can be obtained, and the position where the projection is located is used as the visual position of the sound channel. For each sound channel, the sound channel icon of the sound channel can be displayed at the visual position corresponding to the sound channel on the target page. After identifying the sound channel that needs to emit sound (i.e., the first sound channel) associated with the first sound channel control option, the sound channel icon of the first sound channel on the target page can be highlighted. And, extract the audio corresponding to the first sound channel from the multimedia data, and obtain the amplitude information of the audio, and display a sound wave animation synchronously mapped with the above amplitude information near the highlighted sound channel icon. The sound wave animation synchronously mapped with the amplitude information can emanate from the highlighted sound channel icon.

[0149] In the above embodiments, displaying a sound wave animation synchronously mapped with the amplitude information at the visual position corresponding to the first sound channel enables the visual sound wave to be synchronously mapped with the audio amplitude, enhancing the visual and auditory correlation and improving the multi-modal perception.
