Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular, to a display device and a control method thereof. Background Art

[0002] With the increasing development of display device technology and the improvement of people's demand for the quality of life, display devices such as smart TVs have gradually acquired the function of displaying paintings. For example, as a household appliance product with both decorative and functional features, the picture frame TV has received increasing favor from consumers.

[0003] Taking the picture frame TV as an example, in the scenario where the picture frame TV displays a painting, playing background music can help enhance the artistic atmosphere and improve the user experience. Moreover, currently, there are various different display modes for picture frame TVs, and the display performances of different display modes are different, so as to meet different needs. However, currently, when switching between different display modes of the picture frame TV, there will be a problem of poor experience caused by a large volume difference. Summary of the Invention

[0004] The present application provides a display device and a control method thereof to reduce the volume difference when switching between different modes of the application for displaying images on the display device, and on this basis, improve the user experience of the display device.

[0005] In a first aspect, some embodiments provide a display device, including:

[0006] A display;

[0007] And at least one processor, configured to execute instructions to cause the display device to:

[0008] Receive and respond to an operation instruction to start a target application, start and display an application interface of the target application, where the target application is an application for displaying pictures;

[0009] When receiving an operation instruction to display a first mode, display an application interface of the first mode, control an audio player to play a first audio file associated with the first mode, and collect audio data of the first audio file;

[0010] Receive and respond to a switching instruction to switch to a second mode, switch to display an application interface of the second mode, and control the audio player to play a second audio file associated with the second mode based on a target volume value calculated from the audio data.

[0011] For the display device according to the embodiments of the present application, after starting the target application for displaying pictures, during the process of displaying the application interface of the first application mode and playing the first audio file associated with the first application mode, the audio data of the first audio file is collected. And based on the switching instruction to switch to the second mode, while switching to the application interface of the second mode of the target application, the target volume value is calculated based on the collected audio data of the first audio file, and the playback of the second audio file associated with the second mode is controlled with the target volume value. That is, the target volume value for playing the second audio file associated with the second mode is calculated based on the audio data of the first audio file played previously. The target volume value is associated with the audio data of playing the first audio file, so that the volume of playing the first audio file is related to the volume of playing the second audio file, which helps to reduce the situation of sudden change in the volume of the first audio file and the volume of playing the second audio file, and helps to improve the volume smoothness when switching from playing the first audio file of the first mode to playing the second audio file of the second mode, thereby reducing the volume difference when switching between different modes of the application of the displayed image of the display device, and accordingly improving the user experience of the display device.

[0012] In a second aspect, some embodiments provide a control method for a display device. The display device includes:

[0013] A display;

[0014] And at least one processor configured to execute instructions to cause the display device to:

[0015] Receive and respond to an operation instruction to start a target application, start and display the application interface of the target application, where the target application is an application for displaying pictures;

[0016] When receiving an operation instruction to display the first mode, display the application interface of the first mode, control the audio player to play the first audio file associated with the first mode, and collect the audio data of the first audio file;

[0017] Receive and respond to a switching instruction to switch to the second mode, switch to display the application interface of the second mode, and control the audio player to play the second audio file of the second mode based on the target volume value obtained by calculating based on the audio data.

[0050] In some embodiments, the user input interface 280 can be used to receive instructions from user input.

[0051] Figure 3 For some embodiments provided in this application Figure 1 The hardware configuration block diagram of the control device. 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.

[0052] The control device 100 is configured to control the display device 200, receive input operation instructions from the user, and convert the operation instructions into instructions recognizable and responsive by the display device 200, serving as an interaction intermediary between the user and the display device 200.

[0053] In some embodiments, the control device 100 can be an intelligent device. For example, the control device 100 can install various applications for controlling the display device 200 according to user needs.

[0054] In some embodiments, as Figure 1 shown, after installing the application for controlling the display device 200, the mobile terminal 300 or other intelligent electronic devices can perform functions similar to those of the control device 100.

[0055] 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.

[0056] 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 can include at least one of a WiFi chip 131, a Bluetooth module 132, an NFC module 133, and other near-field communication modules.

[0057] In some embodiments, the control device 100 includes at least one of a communication interface 130 and an input / output interface 140. When the communication interface 130 is configured in the control device 100, such as modules like WiFi, Bluetooth, and NFC, the user input instructions can be encoded through the WiFi protocol, or the Bluetooth protocol, or the NFC protocol and sent to the display device 200. Among the user input / output interfaces 140, the input interface includes at least one of a microphone 141, a touchpad 142, a sensor 143, a button 144, and other input interfaces.

[0058] 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.

[0059] 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.

[0060] 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 may provide a user interface (control the display device), allow the user to interact with the display device 200, and support the running of various application programs.

[0061] 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.

[0062] The operating system can be divided into different modules or layers according to the functions implemented, such as Figure 4 As shown, in some embodiments, the system is divided into four layers, from top to bottom, namely, the application layer (Applications layer) (referred to as "application layer"), the application framework layer (Application Framework layer) (referred to as "framework layer"), the system library layer and the kernel layer.

[0063] In some embodiments, the application layer is used to provide services and interfaces for applications so that the display device 200 can run applications and interact with users based on applications. At least one application can be run in the application layer, and these applications can be window programs, system settings programs, clock programs, etc. that come with the operating system; they can also be applications developed by third-party developers. In specific implementations, the application packages in the application layer are not limited to the above examples.

[0064] The framework layer provides application programming interfaces (APIs) and programming frameworks for applications. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center that determines the actions of applications in the application layer. Applications can access system resources and obtain system services during execution through the API interface.

[0065] like Figure 4As shown, 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.

[0066] In some embodiments, the Activity Manager is used to manage the life cycles of various applications and the usual navigation back functions, such as controlling the exit, opening, and back of the application. The Window Manager is used to manage all window programs, such as obtaining the display screen size, determining whether there is a status bar, locking the screen, taking screenshots, and controlling the changes of the display window. For example, shrinking the display window, jittering the display, distorting the display, etc.

[0067] 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 libraries included in the system runtime library layer, such as C / C++ instruction libraries, to implement the functions that the framework layer is to achieve.

[0068] In some embodiments, the kernel layer is a functional level 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.

[0069] 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. According to 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.

[0070] With the development of technology, the display of paintings through TV devices such as TVs has gradually been widely used. Among them, TV devices such as TVs that can display paintings are usually also called picture frame TVs. Taking the picture frame TV as an example, when the picture frame TV displays a painting, in order to enhance the artistic atmosphere, background music is usually played to enhance the artistic atmosphere. When the target picture frame TV displays a painting, there are different display modes, and the display performance and the requirements for setting or playing background music may vary under different display modes. Therefore, when the picture frame TV switches between different display modes, if the volume difference is large, it will lead to a poor user experience.

[0071] It has been found through research that when switching between different display modes, there are differences in the audio data when playing audio files under different display modes, and the differences in audio data will affect the volume of the played audio files. If the audio data when playing the audio file in the display mode before switching is used to determine the target volume value when playing the audio file in the display mode after switching, it can help improve the volume smoothness when playing the audio file when switching the display mode.

[0072] Accordingly, the display device provided by the relevant embodiments of the present application can achieve the volume smoothness of the audio files played when the target applications such as the picture frame application of the display device are switched between different display modes.

[0073] The display device provided by the embodiments of the present application, referring to Figure 5 as shown, can be implemented through a structure including an application layer, an application framework layer, and a driver layer.

[0074] Among them, the application layer (Applications) can implement multiple applications and the settings of the applications, and it at least includes:

[0075] The picture frame TV application, that is, the target application involved in the present application, which includes a user interface for displaying paintings and playing music. The music can include audio files such as background music and white noise videos;

[0076] The audio intelligent adjustment module: used to adjust the volume when switching between different display modes;

[0077] The background music player: used to play music, which can be implemented based on ExoPlayer, but is not limited thereto.

[0078] The Application Framework layer is a framework that can implement functions such as application management. It provides system services, including but not limited to:

[0079] The AudioManager service, which is used to obtain and set the overall volume of the device;

[0080] APIs (Application Programming Interfaces), including the Visualizer API for audio data capture and the ExoPlayer API for volume control. Among them, the Visualizer API is used to capture audio data, and the ExoPlayer API is used to control the volume of the player.

[0081] The Hardware Abstraction Layer & Drivers, including an audio chip driver, which is responsible for the acquisition and playback of underlying audio data and the processing of the input and output of audio signals.

[0082] Among them, the framework may also include the System Runtime & CoreLibraries layer, specifically including an analysis library for performing audio analysis on the audio data captured by the audio data capture interface, and a player library for providing underlying audio playback support for the player.

[0083] Accordingly, some embodiments of the present application provide a display device, where the display device includes:

[0084] A display;

[0085] And at least one processor configured to execute instructions to cause the display device to:

[0086] Receive and respond to an operation instruction to start a target application, start and display the application interface of the target application, where the target application is an application for displaying pictures;

[0087] When receiving an operation instruction to display the first mode, display the application interface of the first mode, control an audio player to play a first audio file associated with the first mode, and collect audio data of the first audio file;

[0088] Receive and respond to a switching instruction to switch to the second mode, switch to display the application interface of the second mode, and control the audio player to play a second audio file associated with the second mode based on a target volume value obtained by calculating the audio data.

[0089] The target application is an application for displaying paintings, and the paintings it displays can be shown in the form of pictures. In some examples, the target application in the display device can be applications such as a picture frame application, a picture frame TV application, etc., but not limited to these. Among them, a picture displayed by the target application can be a static picture or a dynamic picture, and the embodiments of the present application do not limit this.

[0090] The first mode and the second mode are two different display modes of the target application. Under these two different display modes, the displayed pictures are different. Among them, the pictures being different may be that the picture content is different or the source of the pictures is different. Among them, the pictures may be partially different or all pictures may be different. Under the two different display modes, the played audio files may be different, and the volume characteristics of different audio files are also different.

[0091] The application interface of the target application can be set in various possible ways. Among them, in some examples, the application interface of the target application started and displayed in response to an operation instruction for starting the target application can be the display interface of the target mode of the target application. This target mode can be a preset target mode or the mode ranked first in the mode list formed by multiple modes of the target application, such as Figure 6 the art gallery mode shown.

[0092] In other examples, the application interface of the target application started and displayed in response to an operation instruction for starting the target application can be a display interface including selection items of multiple modes, such as Figure 7 shown. Each selection item of a mode can correspond to the mode name of this mode and the prompt information of this mode, so as to facilitate the user to understand the specific information under different display modes, so that the user can select the required display mode based on this prompt information. Among them, in some examples, each selection item of a mode can also correspond to an image applying this mode to distinguish different modes from the images, but not limited to this.

[0093] Among them, when the application interface of the displayed target application is the display interface of the target mode, if the target mode is different from the first mode expected by the user, the application interface of the first mode can be displayed by receiving an operation instruction for displaying the first mode. Specifically, referring to Figure 6 shown, selection items of other modes can be displayed on the display interface of the target mode, such as Figure 6 the photo collection mode, the comfortable atmosphere mode, the favorite mode, etc. shown.

[0094] When the application interface of the displayed target application is a display interface including selection items of multiple modes, the application interface of the first mode can be displayed by receiving an operation on the selection item of the first mode to receive an operation instruction for displaying the first mode.

[0095] The first audio file associated with the first mode is the audio file played when the picture in the first mode is displayed. Taking the first mode as the comfortable atmosphere mode as an example, the first audio file associated with the comfortable atmosphere mode may include a white noise audio file. The second audio file associated with the second mode is the audio file played when the picture in the second mode is displayed. Taking the second mode as the photo collection mode as an example, the second audio file associated with the photo collection mode may be a non-white noise audio file.

[0096] White noise is noise whose power spectral density is constant across the entire frequency domain. Due to its characteristic of being able to mask other sounds, white noise can, in some cases, serve as an effective background sound to help people concentrate or improve sleep quality. For example, when working or studying in a noisy environment, white noise can help reduce external interference; while when sleeping, white noise can mask night-time noises such as traffic sounds or neighbors' noises, thus helping people fall asleep more easily. In addition, white noise is also used in some therapeutic settings, such as assisting in the treatment of attention deficit hyperactivity disorder or anxiety disorders.

[0097] Among them, the ways of receiving the operation instruction to display the first mode and the switching instruction to switch to the second mode are not limited. It can be determined whether the operation instruction to display the first mode or the switching instruction to switch to the second mode is received through the wireless signal of the received remote control, the voice information collected by the sound collection device, the touch information received by the touch screen of the display device, or the gesture information recognized in the image collected by the image collection device, but it is not limited to this.

[0098] The audio data of the first audio file refers to the data related to the playing audio of the first audio file during the process of playing the first audio file, including but not limited to the energy value of the sound signal emitted when playing the first audio file, etc. The energy value of the audio is the actual physical energy carried in the sound, which represents the power or intensity of the sound. After obtaining the audio data of the played first audio file, the target volume value can be determined based on the audio data of the first audio file.

[0099] Based on the display device according to the embodiments of the present application, after starting the target application for displaying pictures, during the process of displaying the application interface of the first application mode and playing the first audio file associated with the first application mode, the audio data of the first audio file is collected, and based on the switching instruction to switch to the second mode, while switching to the application interface of the second mode of the target application, the target volume value is calculated based on the collected audio data of the first audio file, and the playback of the second audio file associated with the second mode is controlled with the target volume value, that is, the target volume value of the second audio file associated with the second mode is calculated based on the audio data of the first audio file played previously. The target volume value is associated with the audio data of playing the first audio file, so that there is a correlation between the volume of playing the first audio file and the volume of playing the second audio file, which helps to reduce the situation of sudden changes in the volume of the first audio file and the volume of playing the second audio file, helps to improve the volume smoothness when switching from playing the first audio file in the first mode to playing the second audio file in the second mode, thereby reducing the volume difference when switching between different modes of the application of the displayed image of the display device, and accordingly improving the user experience of the display device.

[0100] Among them, when the application interface of the target application started and displayed in response to the operation instruction for starting the target application is the display interface of the target mode of the target application, it can be that on the application interface of the target application started and displayed, other selectable modes and the painting of the target application are displayed simultaneously. The painting can be displayed full screen, and the names of other modes are displayed in a preset area of the display screen of the display device, such as Figure 6 the painting X in the full-screen display art gallery mode shown in, and other modes are displayed, such as photo collection, comfortable atmosphere, favorite, etc.

[0101] In some other examples, when the application interface of the target application started and displayed in response to the operation instruction for starting the target application is the display interface of the target mode of the target application, it can be that after receiving the operation instruction, such as the instruction of a preset button on the remote control, then the other selectable modes shown in the interface such as Figure 6 are displayed, and when no operation instruction is received within a preset time period, the mode names of each display mode are no longer displayed, including not displaying the target mode and not displaying the other switchable modes.

[0102] In some other examples, there can be multiple different sub-modes in the application mode. When displaying the display interface of a certain application mode, while displaying the mode name of the application mode and other selectable application modes, the names of the sub-modes of the application mode and the thumbnail paintings of at least one sub-mode can also be displayed in a preset area of the display screen of the display device. Such as Figure 8As shown, in the area of the display screen adjacent to the lower border, the sub-mode names in the art gallery mode are displayed: oil painting, modern painting, landscape painting, digital painting. At the same time, thumbnails of multiple paintings in the oil painting mode are also displayed. It can be understood that in other embodiments, different sub-modes can also be respectively represented by thumbnails of pictures in different sub-modes, that is, thumbnails of multiple sub-modes are displayed in a preset area of the display screen.

[0103] It can be understood that in other embodiments, the interfaces in different modes of the target application of the display device can also be set in other ways, and the embodiments of the present application do not make specific displays on this.

[0104] Among them, audio data can be collected at different times to calculate the target volume value. The following will give examples in combination with several of these methods.

[0105] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0106] When controlling the audio player to play the first audio file, collect the audio data of the first audio file, calculate the target volume value based on the audio data, and store the calculated target volume value;

[0107] Receive and respond to the switching instruction to switch to the second mode, and query and obtain the stored target volume value.

[0108] When storing the calculated target volume value, the target volume value can be stored in the local storage area of the display device so that the target energy value can be obtained in time when needed.

[0109] Among them, it can be during the process of playing the first audio file, the audio data of the first audio file is collected in real time, and after the duration of the first audio file reaches the preset duration (which can be called the first duration in the embodiments of the present application), the target energy value is calculated based on the audio data corresponding to the first duration.

[0110] In some examples, when calculating the target energy value based on the audio data corresponding to the first duration, the target energy value can be directly stored, and the target energy value is not updated during the process of playing the first audio file this time.

[0111] In other examples, the target energy value can be calculated based on the audio data corresponding to the first duration, and after the target energy value is stored, every subsequent preset duration (which can be called the second duration in the embodiments of the present application), a new target energy value can be calculated based on the audio data corresponding to the second duration, and the stored target energy value is updated with the new target energy value. Among them, the second duration and the first duration can be the same or different.

[0112] In some other examples, a target energy value can be calculated based on the audio data corresponding to the first duration, and after storing the target energy value, it can be detected that the display device plays the audio data as a whole. When the audio data played as a whole changes, a new target volume value can be calculated based on the audio data played as a whole, and the stored target energy value can be updated with the new target energy value. Among them, in the case where the target volume value is updated every second duration, after calculating a new target volume value based on the audio data played as a whole and updating the stored target energy value with the new target volume value, the timing of the second duration can be restarted.

[0113] Based on the display device of this embodiment, while playing the first audio file associated with the first mode, it can collect the audio data of the first audio file in real time and calculate and store the target volume value. Thus, when receiving a switching instruction to switch to the second mode, the stored target volume value can be queried as the volume for playing the second audio file associated with the second mode, which is simple, convenient and highly efficient.

[0114] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0115] When controlling the audio player to play the first audio file, collect and store the audio data of the first audio file;

[0116] Receive and respond to a switching instruction to switch to the second mode, and calculate the target volume value based on the stored audio data.

[0117] When storing the audio data of the first audio file, the storage location of the audio data of the first audio file is not limited. For example, the target volume value can be stored in the local storage area of the display device so that the audio data can be obtained in time when needed for calculating the target energy value.

[0118] Based on the display device of this embodiment, while playing the first audio file associated with the first mode, it can collect and store the audio data of the first audio file in real time, and when receiving a switching instruction to switch to the second mode, calculate the target volume value based on the stored audio data, and use the calculated target volume value as the volume for playing the second audio file associated with the second mode. Thus, calculating the target volume value is performed only when a switching instruction is received, which helps to reduce computing resources and can improve the accuracy of the obtained target volume value.

[0119] The method for calculating the target energy value is not limited. In some examples, the processor is further configured to execute instructions to cause the display device to:

[0120] When playing the first audio file, sample the audio of playing the first audio file to obtain a plurality of sampling samples, and calculate the energy value of each sampling sample. The audio data includes the energy value;

[0121] Determine the maximum energy value among the plurality of energy values, and calculate and determine the energy mean value and the energy average value based on the plurality of energy values;

[0122] Calculate and obtain the target volume value based on the maximum energy value, the energy mean value, and the energy average value.

[0123] Wherein, the manner of determining the maximum energy value among the plurality of energy values and calculating and determining the energy mean value and the energy average value based on the plurality of energy values is not limited.

[0124] Taking the waveform data obtained by sampling the audio of playing the first audio file as an example, the root mean square of each energy value can be used as the energy mean value, that is, the square root of the mean of the sum of the squares of the energy values of each sampling point can be obtained to obtain the energy mean value, which can be expressed by the formula as:

[0125] 。

[0126] Wherein, represents the energy mean value, N represents the number of waveform data samples, is the energy value of the i-th sample. Through the energy mean value of multiple energy values, the average amplitude of the energy values of multiple sampling points can be described.

[0127] When obtaining the maximum value of the energy value, the maximum value can be found by traversing the waveform data array, which can be expressed by the formula as:

[0128] 。

[0129] Wherein, represents the maximum value of the energy values of N samples.

[0130] The maximum value of the energy value represents the maximum energy value of the played first audio file. In the case where the first audio file is a white noise audio, it represents the maximum energy value of the white noise audio, reflecting the instantaneous impact of the audio.

[0131] When obtaining the energy average value, the energy average value can be obtained by adding up all the sample values and dividing by the number of samples, which can be expressed by the formula as:

[0132] 。

[0133] Wherein, Represents the average energy value of N samples. The average energy value reflects the overall energy level of the first audio file being played. In the case where the first audio file is a white noise audio, it represents the overall energy level of the white noise audio, reflecting the continuous intensity of the audio.

[0134] Based on the maximum energy value, the energy mean, and the average energy value, there is no limit to the way of calculating the target volume value. In some examples, the processor is further configured to execute instructions to cause the display device to:

[0135] Calculate a weighted energy value based on the maximum energy value and the average energy value;

[0136] Calculate a target energy value based on the current volume value, the energy mean, and the weighted energy value.

[0137] In some examples, based on the energy mean , the maximum energy value , and the average energy value , there is no limit to the way of calculating the target volume value, and it can be carried out in the following way:

[0138] First, calculate a weighted energy value based on the maximum energy value and the average energy value . In one example, it can be the geometric mean of the maximum energy value and the average energy value as the weighted energy value, that is, it can be the square root of the product of the maximum energy value and the average energy value as the weighted energy value, which can be expressed by the formula:

[0139] .

[0140] Wherein, represents the weighted energy value.

[0141] Then, calculate a target energy value based on the current volume value, the energy mean, and the weighted energy value. In a specific example, the target energy value can be the product of the ratio of the energy mean to the weighted energy value and the current volume value, which can be expressed by the formula:

[0142] .

[0143] Wherein, represents the target volume value, represents the current volume value of the player.

[0144] For the display device based on this embodiment, the audio data obtained by collecting the playback of the first audio file includes energy values. Based on this, the maximum energy value, energy mean value, and average energy value of these energy values are calculated, and the target volume value is calculated based on the maximum energy value, energy mean value, and average energy value. Thus, both the energy peak of the playback of the first audio file and the average value of these energy values are considered, and the energy mean value that can describe the average amplitude of the energy values of multiple sampling points is considered, so that the calculated target volume value can reflect the comprehensive situation of multiple energy values. The target volume value determined based on this can help further improve the smoothness of switching from playing the first audio file associated with the first mode to playing the second audio file associated with the second mode, and help further improve the user experience.

[0145] During the use of the display device, in the second mode, multiple different pictures may be displayed, and there may be multiple second audio files played. Therefore, in the second mode, it involves the switching of the displayed pictures and the switching of the played second audio files, and different processing can be done according to different needs. The following gives examples in combination with several of these methods.

[0146] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0147] During the process of controlling the audio player to play the second audio file of the second mode, collect the audio data of the second audio file;

[0148] Calculate a new target volume value based on the audio data of the second audio file:

[0149] When switching to play the next audio file in the second mode, control the audio player to play the next audio file adjacent to the second audio file with the new target volume value.

[0150] Among them, the method of collecting the audio data of the second audio file and calculating a new target volume value based on the audio data of the second audio file can be the same as the method of collecting the audio data of the first audio file and calculating the target volume value based on the collected audio data of the first audio file, which will not be elaborated here.

[0151] For the display device based on this embodiment, when switching the played audio file in the second mode of the target application, a new target volume value calculated based on the audio data of the previous second audio file played can be used, and the next audio file adjacent to it can be played with this new target volume value, thereby further improving the volume smoothness of adjacent second audio files in the second mode, helping to further improve the smoothness of playing different audio files, and on this basis helping to further improve the user experience.

[0152] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0153] During the process of controlling the audio player to play the second audio file in the second mode, collect the audio data of the second audio file;

[0154] Calculate a new target volume value based on the audio data of the second audio file:

[0155] When switching to play the next image in the second mode, control the audio player to play the audio file associated with the next image, and control the audio player to play the audio file associated with the next image based on the new target volume value.

[0156] Based on the display device of this embodiment, when switching the audio file played in the second mode of the target application, a new target volume value can be calculated based on the audio data of playing the previous second audio file, and the audio file associated with the adjacent next image can be played with this new target volume value, thereby further improving the volume smoothness of adjacent audio files in the second mode, contributing to further improving the smoothness of playing different audio files, and on this basis, contributing to further improving the user experience.

[0157] Among them, the audio file associated with the image can be music stored in the local memory of the display device, music stored in the external memory of the display device, music in the server communicatively connected to the display device, or music including multiple different sources. The embodiments of the present application do not limit the sources and types in the music list.

[0158] The determination method of the audio file associated with the image is not limited. Some methods are exemplified below.

[0159] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0160] Identify the image style type of the image currently displayed on the display;

[0161] Determine the target music that matches the image style type;

[0162] Use the matching target music as the audio file associated with the currently displayed image.

[0163] The image style type is information characterizing the image style. Some possible image style types may include cartoon style, anime style, portrait style, landscape, etc., but are not limited thereto.

[0164] The image style type of an image can be recognized in various possible ways. In some examples, an image style recognition model can be used to perform image style recognition on the image to obtain the image style type. The style recognition model can be obtained through training, and the specific way of training to obtain the style recognition model is not limited.

[0165] Based on the display device of this embodiment, the image style type of the image currently displayed on the display can be recognized, and the target music that matches the image style type can be determined as the target music associated with the image, so that the target music played is matched with the style type of the played image, further improving the flexibility of the control of the display device to play background music while displaying the target application.

[0166] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0167] Find the audio file associated with the image displayed by the target application based on the association relationship;

[0168] Control the music player to play the audio file.

[0169] The association relationship between the image and the audio file can be achieved in various possible ways, such as through an association list or a link address, etc. Taking the association list as an example, the audio file associated with the currently displayed image can be found from the association list.

[0170] When there is an associated audio file for the image, when the image is displayed, the played audio file can be switched to play the audio file corresponding to the image, so that the played music can be more adapted to the image, which is more conducive to enhancing the immersion.

[0171] Based on the display device of this embodiment, the image displayed by the target application is associated with a corresponding audio file, so that each can have a corresponding audio file with an association setting, and each has a personalized background music. Therefore, when the image is displayed through the target application, if the music player plays music, the music of the associated audio file can be directly played, further improving the flexibility of the control of the display device to play background music while displaying the target application.

[0172] In the actual use process of the display device, when the second audio file in the second mode is played, the volume of the whole machine player of the display device may change. There may be various reasons for the change in the volume of the whole machine player, such as the user setting the volume of the whole machine of the display device through the remote control, the keys of the display device or voice, or the start of the timed task of the display device, and the display device needs to play other audio files associated with the timed task, etc., but not limited to this.

[0173] Accordingly, in some embodiments, the processor is further configured to execute instructions to cause the display device to:

[0174] During the process of controlling the audio player to play the second audio file associated with the second mode, monitor the audio data played by the whole machine;

[0175] According to the audio data played by the whole machine, calculate a new target volume value, and control the audio player to play the second audio file associated with the second mode with the new target volume value.

[0176] The manner of calculating the new target volume value according to the audio data played by the whole machine may be the same as the manner of calculating the target volume value based on the audio data of the collected first audio file, which will not be elaborated here.

[0177] Based on the display device of this embodiment, in the second mode of the target device, it also monitors the audio data played by the whole machine in real time, obtains a new target volume value based on the audio data played by the whole machine, and controls the playback of the second audio file associated with the second mode with the new target volume value. Therefore, when the volume of the whole machine player changes, it can also update the target volume value of the second audio file associated with the second mode in real time, which helps to meet the requirement of volume smoothness when the volume value of the whole display device changes, and helps to further improve the user experience.

[0178] During the use of the display device, in the case of having multiple different display modes, after switching to the second mode, it may also switch to other display modes. As shown in Figure 6 After switching to the art gallery mode, it may also switch to the photo collection mode or the favorite mode. In this case, it can be processed according to actual needs. The following takes several ways as examples for illustration.

[0179] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0180] During the process of controlling the audio player to play the second audio file of the second mode, collect the audio data of the second audio file;

[0181] Receive and respond to the switching instruction to switch to the third mode, switch to the application interface of the third mode, and calculate a new target volume value based on the audio data of the second audio file: control the audio player to play the third audio file associated with the third mode with the new target volume value.

[0182] Based on the display device of this embodiment, when the target application switches from the second mode to the third mode, the display device can calculate a new target volume value based on the audio data of the second audio file, that is, the target volume value for playing the third audio file associated with the third mode is calculated based on the audio data of the second audio file played previously. This new target volume value is associated with the audio data of the second audio file played, so that the volume of playing the second audio file is related to the volume of playing the third audio file, which helps to reduce the situation of sudden changes in the volume of the second audio file and the volume of playing the third audio file, and helps to improve the volume smoothness when switching from playing the second audio file in the second mode to playing the third audio file in the third mode, thereby reducing the volume difference when switching between different modes of the application of the display image of the display device, and accordingly improving the user experience of the display device.

[0183] In some examples, the processor is further configured to execute instructions to cause the display device to:

[0184] Receive and respond to a switching instruction to switch to the third mode, switch to the application interface of the third mode, and control the audio player to play the third audio file associated with the third mode at the target volume value.

[0185] Based on the display device of this embodiment, when the target application switches from the second mode to the third mode, the display device can not switch the target volume value, so that in both the second mode and the third mode, the audio file is played at the same target volume value, further reducing the situation of volume value changes, further improving the immersive experience of watching images in the case of playing background music in the second mode and the third mode, and further adjusting the user experience of the display device.

[0186] Among them, in the above example, the type of the third mode is not limited. Taking the second mode as the art gallery mode as shown in Figure 6 For example, the third mode can be a photo collection mode or a favorite mode.

[0187] Among them, taking the first mode as the comfortable atmosphere mode and the white noise audio being played in the first mode as an example, the third mode is different from both the second mode and the first mode.

[0188] In some specific examples, the first audio file associated with the first mode is a white noise audio, and the second audio files associated with the second mode and the third mode are non-white noise audios.

[0189] Due to the characteristics of white noise, the volume of white noise is lower than that of ordinary music. Therefore, when switching from the first mode of playing white noise audio to the second mode of playing non-white noise audio, there will be a more obvious sudden change in volume. Based on the solution of the present application, when switching from the first mode of playing white noise audio to the second mode of playing non-white noise audio, the target volume value will be calculated based on the audio data of the played white noise audio, and the played non-white noise audio will be played with the target volume value, significantly reducing the sudden change in volume and further improving the smoothness of volume playback of the display device with white noise audio playback.

[0190] Based on the above examples, the following will be described in conjunction with the interaction sequence diagrams in some specific examples. Among them, in the following examples, the first mode is Figure 6 the comfortable atmosphere mode shown in, and the second mode is other modes other than the comfortable atmosphere mode as an example for description.

[0191] Combined with Figure 9 and Figure 10 As shown, when the user opens the framed TV application, the framed TV application starts system initialization and starts the audio intelligent adjustment module.

[0192] After the audio intelligent adjustment module is started, it performs initialization operations, which include but are not limited to creating necessary instances and setting initial parameters.

[0193] When switching to play white noise audio in the comfortable atmosphere mode of the framed TV application, the audio intelligent adjustment module calls the audio data capture interface to start obtaining the currently played white noise audio data, and the audio data capture interface will return the captured audio data to the audio intelligent adjustment module. When playing white noise video in the comfortable atmosphere mode, the process of capturing audio data can be continuously carried out.

[0194] When switching from the comfortable atmosphere mode to other modes of the framed TV application, such as the art gallery mode, photo collection mode or favorite mode, detecting this mode switching operation, switching to display the paintings in the new display mode, the framed TV application detects the operation of the user switching from white noise video to background music playback, calls the audio intelligent adjustment module to analyze the obtained audio data detected in the comfortable atmosphere mode, calculates key parameters such as the energy value, maximum value, average value of the audio, calculates the target volume value of the background music player based on these parameters, and notifies the calculated target volume to the background music player.

[0195] After the background music player receives the notification, it calls the volume control interface. For example, through the setVolume method, it sets the volume of the background music to the target volume value. After the volume control interface completes the volume setting, it can return the volume setting result to the background music player. The background music player starts playing the background music so that the user can hear the background music that matches the volume characteristics of the white noise.

[0196] During the process of playing the background music, the framed TV application continuously monitors whether the overall volume of the whole machine changes. If it detects that the overall volume of the whole machine changes, the audio intelligent adjustment module recalculates the target volume of the background music based on the changed overall volume of the whole machine, notifies the recalculated target volume to the background music player, and the background music player calls the volume control interface again to set the volume of the background music to the new target volume. After the volume control interface completes the volume setting, it can return the volume setting result to the background music player. The background music player continues to play the background music, and the user can hear the background music adapted according to the change of the overall volume of the whole machine.

[0197] Through the above process, the framed TV audio intelligent adjustment system can intelligently adjust the volume of the background music when switching between different audio contents, achieve a smooth transition of the volume, and adapt to the change of the overall volume of the whole machine, providing a more comfortable and convenient user experience.

[0198] Among them, as combined Figure 6 、 Figure 8 As shown, since in modes such as the art gallery mode, photo collection mode, and favorite mode, the played is background music, which is non-white noise audio and has different characteristics from the white noise audio played in modes such as the comfortable atmosphere mode. Therefore, when switching between different modes of playing non-white noise audio, the target volume value can be kept unchanged, and a smooth volume output effect can also be obtained.

[0199] Based on the display device as described above, some embodiments of the present application further provide a control method for a display device.

[0200] Referring to Figure 11 As shown, the control method for a display device in some embodiments includes:
