Description

Display device and multi-window audio parameter adjustment method

technical field

The present application relates to the technical field of smart TVs, and in particular, to a display device and a method for adjusting multi-window audio parameters.

Background technique

Smart TV is a TV product based on Internet application technology, with an open operating system and chip, and an open application platform, which can realize two-way human-computer interaction function, and integrate various functions such as audio-visual, entertainment, and data. Diversity and individual needs. The smart TV can present user interfaces such as UI interface and playback interface through various windows to display specific screen content. For example, in the process of using the smart TV, the user can choose to play the local or network multimedia resources, and the smart TV displays the media resources screen selected by the user to play through the play window in response to the user's operation.

For some smart TVs, you can also turn on multi-window mode, which is used to display two or more windows at the same time. In multi-window mode, different screen contents can be displayed through different windows. For example, after entering the multi-window mode, the smart TV can display two windows on the screen at the same time, namely window 1 and window 2. Among them, window 1 displays the screen content of video 1, and window 2 displays the screen content of video 2. The two windows play video images at the same time, so that users can watch or preview multiple video contents together.

However, in the process of using multiple windows to play video media images on a smart TV, the played video media images usually have synchronous audio signal outputs, and multiple windows are usually in independent playback processes. When the user adjusts the playback volume , it is easy to cause a large difference in the volume adjustment degree corresponding to each window, that is, the volume adjustment is inaccurate, which reduces the user experience.

Alternatively, the user may input a user command by inputting a specific sound or gesture, and the user input interface recognizes the sound or gesture through a sensor to receive the user input command.

In some embodiments, a "user interface" is a medium interface for interaction and information exchange between an application program or an operating system and a user, which enables conversion between an internal form of information and a form acceptable to the user. A commonly used form of user interface is a graphical user interface (Graphic User Interface, GUI), which refers to a user interface related to computer operations displayed in a graphical manner. It can be an icon, window, control and other interface elements displayed on the display screen of the electronic device, wherein the control can include icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, Widgets, etc. at least one of the visual interface elements.

Referring to FIG. 4 , in some embodiments, the system is divided into four layers, from top to bottom, the applications layer (referred to as “application layer”), the application framework layer (referred to as “framework layer”) "), the Android runtime (Android runtime) and the system library layer (referred to as "system runtime library layer"), and the kernel layer.

In some embodiments, at least one application program runs in the application program layer, and these application programs may be a Window program, a system setting program, or a clock program that comes with the operating system; they may also be developed by third-party developers. s application. During specific implementation, the application package in the application layer is not limited to the above examples.

The framework layer provides an application programming interface (application programming interface, API) and a programming framework for the applications of the application layer. The application framework layer includes some predefined functions. The application framework layer is equivalent to a processing center, which decides to let the applications in the application layer take action. The application program can access the resources in the system and obtain the services of the system during execution through the API interface.

As shown in FIG. 4 , the application framework layer in the embodiment of the present application includes managers (Managers), content providers (Content Provider), etc., wherein the manager includes at least one of the following modules: the activity manager (ActivityManager) is used with Interact with all activities running in the system; Location Manager is used to provide system services or applications with access to system location services; Package Manager is used to retrieve files currently installed on the device. Various information related to the application package; Notification Manager (Notification Manager) is used to control the display and clearing of notification messages; Window Manager (Window Manager) is used to manage icons, windows, toolbars, wallpapers and desktops on the user interface part.

Based on the above-mentioned display device 200 , the user can control the display device 200 to enter a multi-window mode during the process of using the display device 200 . In the multi-window mode, the display 260 of the display device 200 can simultaneously display two or more windows in the user interface, and each window can independently display different contents. For example, as shown in FIG. 5a, after the display device 200 enters the multi-window mode, the display 260 can display the first window and the second window at the same time, wherein the first window can be used to display the playback screen of the media asset A, and the second window It can be used to display the playback screen of media asset B.

In different usage scenarios, the content of the pictures displayed in the multi-window is different, and the corresponding picture types can also be different. For example, the playback picture of the media asset A is displayed in the first window, and the setting menu picture is displayed in the second window. That is, different windows display different types of interfaces at the same time, the first window displays the play interface, and the second window displays the home page interface.

The user can control the display device 200 to enter the multi-window mode through specific interactive actions. For example, as shown in FIG. 5b, a multi-window mode switching button may be set on the control device 100 supporting the display device 200. When the user presses the multi-window mode switching button, the display device 200 can be controlled to enter the multi-window mode, that is, control the The display 260 of the display device 200 displays a plurality of windows. As shown in FIG. 5c, a multi-window mode switching option can also be set in the UI interface of the display device 200. When the user clicks the switching option, the display device 200 can be controlled to enter or exit the multi-window mode.

In some embodiments, the display device 200 can also detect the usage status of the user in real time, and determine whether the user has a requirement for multi-window display, so as to intelligently switch the multi-window mode or provide a multi-window mode switching option according to the user's requirement. For example, as shown in FIG. 5d, in the process of playing the media asset screen on the display device 200, if there is a video chat request, it can automatically switch to the multi-window mode, so that the display device 200 can display the media asset screen through the first window; The second window displays the video chat screen. For another example, as shown in FIG. 5e, in the process of displaying the media asset screen on the display device 200, a plurality of recommended program options may also be displayed on the right side of the user interface. After the user selects any recommended program option and confirms it, the user can control The display device 200 enters the multi-window mode, that is, the original media asset playback picture is displayed through the first window, and the playback picture corresponding to the recommended program is displayed through the second window.

When the display device 200 is in the multi-window mode, not only can different screen contents be displayed simultaneously through multiple windows, but also audio content corresponding to the screen can be output while displaying the screen contents. For example, as shown in FIG. 6a, program 1 and program 2 are simultaneously played on the display device 200, the picture of program 1 is displayed in the first window, and the picture of program 2 is displayed in the second window. At the same time, the sound of program 1 is played through the local speaker, and the sound of program 2 can be played through an external USB speaker or an audio output device such as a Bluetooth speaker. At this time, as shown in Figure 6b, the SOC system side obtains the output device Out1 of the first window and the corresponding volume Vol1 of the window from the dual-window mode database, switches the output device of the first window to Out1, and refreshes the volume value to Vol1; Obtain the output device Out2 of the second window and the corresponding volume Vol2 from the dual-window mode database, switch the output device of the second window to Out2, and refresh the volume value to Vol2. In this way, when multiple pictures are displayed synchronously, sounds are also played through different audio output devices, so as to achieve the purpose of not interfering with each other.

In the above example, the display device 200 may output audio signals through the audio output interface, and output sounds by connecting different audio output devices through the audio output interface. Specifically, it may include: outputting sound through a native audio output device of the display device 200, such as a speaker of the display device 200, etc.; and outputting sound through an audio output device externally connected to the display device 200, for example, through a wired or wireless connection To the audio equipment, headphones, etc. of the display device 200 . For convenience of description, this application refers to the audio output interface connected to the local audio output device as the local interface; the audio output interface connected to the external audio output device is referred to as the external interface.

It should be noted that, in order to obtain a better interactive experience, there is generally only one window for outputting audio through the local interface, and other windows can output audio through the external interface according to the number of external audio devices, as shown in Figure 6c, the display device 200 can also display three windows at the same time for displaying different programs respectively, and the first window and the third window are connected to the audio device through the external interface to output sound, and the second window uses the local interface to connect the local speaker to output the sound.

When the display device 200 is playing media asset data or other data with audio and video content, it can also perform interactive actions to control the audio and video data output process, including image quality control and sound control. For example, the display device 200 can receive the user's control instruction, call the setting key UI menu according to the control instruction, display the volume adjustment control of the current window in the OSD layer menu, and receive the user's instruction to select volume adjustment in this option again, thereby completing the display Device 200 volume adjustment. The user can set the volume to any specific value in the range of 0-100 according to the UI, and the display device 200 adjusts the gain of the audio output channel according to the set volume value, so that the local speaker or the external audio output device outputs sound according to the volume value. .

In the multi-window mode, the display device 200 will simultaneously output content corresponding to multiple windows. Therefore, when adjusting the volume of multiple windows according to the traditional audio parameter adjustment method, the adjustment operation cannot be performed accurately for each window. To this end, a display device 200 is provided in some embodiments of the present application. The display device 200 includes a display 260 , an audio output interface 270 and a controller 250 . The display 260 is used for displaying a user interface, and the displayed user interface may include multiple windows when the display device 200 is in a multi-window mode. The audio output interface 270 can be connected to a local speaker and/or an external audio device for outputting audio to form an audio output path. The controller 250 is configured to execute a multi-window audio parameter adjustment method for performing accurate audio parameter adjustment operations on the display device 200 in the multi-window mode.

As shown in FIG. 7 , the specific implementation of the multi-window audio parameter adjustment method will be described below by taking volume adjustment as an example. It should be understood that the audio parameter adjustment method provided in the embodiment of the present application also includes volume adjustment in addition to volume adjustment. other audio parameter adjustments. For example, surround parameters, bass parameters, mid-range parameters, treble parameters, timbre parameters, pitch parameters, etc. Among them, the method for adjusting the volume includes the following:

Get the control command entered by the user to adjust the volume. The controller 250 of the display device 200 can receive various control instructions input by the user during the use of the user, and different control instructions have different functions correspondingly. Among them, some control commands can be used to adjust the volume. For example, the user can press the volume "+" or volume "-" key on the remote control to input a control command to adjust the volume; and can also control the display device 200 to display the volume setting by calling up the menu option and selecting "sound-volume" menu to enter control commands for adjusting the volume.

In addition, when the display device 200 has a built-in intelligent voice system, the user can also control the display device 200 to adjust the volume by inputting a voice command. For example, the user can input voice content such as "adjust the volume to 75", "increase the volume", "decrease the volume" through a far-field microphone or an external sound collection device, so that the intelligent voice system responds to the corresponding voice content to form a The control instruction for adjusting the volume controls the display device 200 to perform volume adjustment settings.

It should be noted that the above-mentioned control instructions for adjusting the volume are only used as several interaction examples, and do not limit the interaction modes of the solution of the present application. Enter a control command for adjusting the volume. For example, the control instruction can also be input through a somatosensory operation, a touch operation, and a physical key operation on the display device 200.

After receiving the control instruction for adjusting the volume, the display device 200 may detect the current focus window in response to the control instruction input by the user. Wherein, the focus window is a window with a focus mark among the multiple windows of the current user interface. The focus mark refers to the graphics used to assist the user to perform interaction and mark the interactive object. For example, the focus mark can be a selection box, and the user can control the selection box to switch between different options through the "up, down, left, right" direction keys on the remote control.

The controller 250 can determine which window is the focus window by detecting the position of the focus cursor. For example, as shown in FIG. 8, if the current user interface includes two windows, when the focus cursor is on the first window, it can be determined that the current focus window is the first window; and when the focus cursor is on the second window, it can be determined that The current focus window is the second window.

Obviously, since the UI layout interface can be displayed in each window, that is, as shown in FIG. 9a, in some embodiments, the focus mark is not on the window but on any option in the window. Therefore, when detecting the focus window, it is also possible to further detect whether there is a focus mark within the scope of the window. When the focus mark is within the range of the first window, the focus window is determined to be the first window; when the focus mark is within the range of the second window, the focus window is determined to be the second window.

Similarly, if the current user interface includes more than two windows, the position of the focus mark can also be detected to determine the window with the focus mark as the current focus window. For example, as shown in FIG. 9b, if the current user interface includes three windows, by detecting the focus flag, it is determined that the current focus flag is in the second window, and the second window is determined to be the focus window.

According to the detection result of the focused window, the controller 250 may acquire the current playback volume for the focused window. The current playback volume can be acquired through a database in the display device 200 for recording setting parameters or playback parameters. For example, the controller 250 can obtain whether the first window or the second window needs to be adjusted according to the focus position of the window. If the focus is marked on the first window, the system can obtain the current audio output device from the database corresponding to the first window. , and get the current volume value according to the audio output device.

The current playback volume can also be obtained in other ways. For example, for an external audio output device that does not support the database of the display device 200, the output volume of the audio output device can also be collected through the built-in microphone of the display device 200 or an external audio input device to obtain Current volume value.

While acquiring the current volume value, the controller 250 may also acquire the volume adjustment amount input by the user. The volume adjustment amount can be obtained by parsing the control instruction input by the user, or can be obtained by parsing the interactive instruction input by the user after the focus window is detected. Obviously, for different volume adjustment situations, the volume adjustment amount can be presented as different values. That is, when the user controls to increase the output volume, the volume adjustment amount is a positive value; when the user controls to decrease the output volume, the volume adjustment amount is a negative value. For example, while obtaining the current volume value of 30, it can be obtained through the analysis of the control command input by the user that the user wants to increase the output volume by 20, then the volume adjustment amount is +20; similarly, it is obtained through the analysis of the control command input by the user that the user wants to lower the output volume. If the output volume is 20, the volume adjustment amount is -20.

The adjusted volume is then calculated according to the current playback volume and the volume adjustment amount, where the adjusted volume is equal to the sum of the current volume and the volume adjustment amount. For example, the adjusted volume=30+20=50, that is, the controller can set the audio output channel gain of the focus window to 50% according to the adjusted volume.

It can be seen that the display device 200 provided by the above embodiment can first detect the window where the current focus mark is located after acquiring the control instruction for adjusting the volume, acquire the current playback volume of the focus window, and then calculate the adjusted volume in combination with the volume adjustment amount input by the user , so as to set the gain of the audio output channel of the focus window according to the adjusted volume to complete the volume adjustment. When the display device 200 is in the multi-window mode, the playback volume in the window is individually adjusted according to the position of the focus mark, so as to accurately complete the volume adjustment.

In the above-mentioned embodiment, the controller 250 can adjust the volume individually for the focus window, and the determination of the focus window will directly affect the target of volume adjustment. Therefore, in order to determine the focus window and detect the current volume of the focus window, in some embodiments, the controller 250 may detect the position of the focus mark after acquiring the control instruction input by the user, and determine that the window where the focus mark is located is The current focus window. And, as shown in FIG. 10 , after the focus window is determined, the identification ID of the focus window can be obtained. The identification ID refers to a character string set according to the number of windows in the current user interface and used to distinguish each window. For example, when the user interface includes two windows, the identification IDs of the first window and the second window are "window01" and "window02", respectively. After it is determined that the first window is the focus window, the identification ID of the current focus window may be obtained as window01.

The controller 250 then queries the current playing volume in the database according to the identification ID. Wherein, the database may record the current setting parameters of the display device 200 , including setting parameters such as playback volume, playback brightness, contrast, color mode, and image quality processing parameters. In the multi-window mode, each window may correspond to a set of setting parameters, and each set of setting parameters and the identification ID of the window may form a table entry and be stored in the database. To this end, after the window identification ID is obtained, matching can be performed in the database according to the identification ID as an index value to obtain an entry corresponding to the identification ID, and then the current playback volume can be queried.

For the displayed volume adjustment control, in some embodiments, after the current playback volume is queried, the volume adjustment control pattern may also be set according to the current playback volume. The volume adjustment control may be set to a specific shape according to the UI layout characteristics of the display device 200 . For example, the volume control can be a scroll bar or a slide ring with a float that indicates the current volume. Therefore, after obtaining the current volume, the position of the float pattern can be set according to the current volume, so as to obtain a volume adjustment control pattern that conforms to the specific value of the current volume.

After the volume adjustment control pattern is set, the controller 250 may further display the volume adjustment control after the adjustment pattern in the focus window, so as to indicate the window in which the user is currently performing volume adjustment through the displayed adjustment pattern. It can be seen that in this embodiment, different volume adjustment control patterns can be set according to different current volumes, and the volume adjustment control can be displayed in the focus window. While realizing the individual adjustment for the window, it is convenient for the user to distinguish the current volume adjustment window. Reduce the possibility of user misoperation.

It should be noted that the method of setting the volume adjustment control pattern according to the current playback volume in this embodiment is not limited to the form in the above example, and can also be combined with text, animation, color and other forms on this basis to complete the volume adjustment control. Setting, so that the displayed volume adjustment control can not only display the current volume, but also facilitate the user to perform volume adjustment operations.

In order to enable the controller 250 to calculate the adjusted volume according to the current volume and the volume adjustment amount input by the user, after the control displays the volume adjustment control in the focus window, the controller 250 can further obtain the volume adjustment amount input by the user. Wherein, when the control command input by the user includes the volume adjustment value, the controller 250 can directly obtain the volume adjustment value from the control command; when the control command input by the user does not include the volume adjustment value, the controller 250 needs to further receive The interactive action entered by the user, and the volume adjustment amount is determined according to the interactive action.

That is, in some embodiments, the controller 250 may first obtain the interactive action instruction input by the user on the volume adjustment control, and parse the interactive action instruction to obtain the action amplitude in the interactive action instruction, and then calculate the volume adjustment amount according to the action amplitude. .

Obviously, according to different specific interaction modes, the interactive action instructions that the user can input are also different. Moreover, according to the specific shape of the volume adjustment control, the user can use different interactive actions to complete the input of the volume adjustment amount. For example, after the volume adjustment control is displayed in the first window, the float position in the volume adjustment control can be adjusted by a remote control or a touch operation, and the controller 250 calculates the volume adjustment amount according to the moving distance of the float position.

When the control instruction for adjusting the volume is input by the user pressing the volume key of the control device, the controller 250 can also obtain the volume adjustment amount by analyzing the pressing action. The pressing action may include a clicking action and/or a long pressing action. For example, when the control command for adjusting the volume is input by the user by pressing the volume "+" key on the remote control, the specific adjustment amount of the current volume adjustment can be parsed through the control command, that is, the volume can be detected by detecting the volume The number of button clicks or the long-press time to obtain the volume adjustment amount.

Therefore, in order to obtain the volume adjustment amount, as shown in FIG. 11 , in some embodiments, the controller 250 may parse the control instruction first, and calculate the volume adjustment amount according to the analysis result. If the pressing action is a click action, obtain the volume adjustment step corresponding to a single click action to obtain the volume adjustment amount. For example, the control system of the display device 200 sets the volume adjustment step of a single click to 5, and the user clicks the volume "+" key once, and the corresponding volume adjustment is +5%. When the user wants to increase the volume by 20%, the input of the volume adjustment amount can be completed by clicking the volume "+" key four times.

If the pressing action is a long pressing action, record the pressing duration of the long pressing action, and calculate the volume adjustment amount according to the pressing duration. For example, it is set in the control system of the display device 200 that every 0.1s increase in the pressing time corresponds to an increase or decrease of the volume by 1%. After the user long presses the volume "+" key for 1s, the volume adjustment amount can be increased by 10%. %.

In some embodiments, after the control instruction is input, the display device 200 may further set a parameter adjustment control pattern according to the audio parameter adjustment amount, wherein the parameter adjustment control includes a floating logo pattern and a stroke pattern. For example, when performing volume adjustment, the controller 250 may set the volume adjustment control pattern according to the control instruction after the user inputs the control instruction. If the pressing action corresponding to the control command is a click action, after each click action is input, the position of the floating sign pattern on the stroke pattern is modified according to the adjustment step; if the pressing action is a long pressing action, during the duration of the long pressing action, the The preset speed moves the position of the floating logo pattern on the stroke pattern.

The above-mentioned embodiment can adjust the volume of each window independently of each other for the display device 200 in the multi-window mode. Obviously, in order to reduce the amount of data processing and reduce invalid judgment, it is also possible to detect whether the display device 200 is in the multi-window mode, that is, as shown in FIG. Number of playback processes. Usually, a window can correspond to one playback process, and a window without a playback process usually does not output an audio signal. Therefore, by traversing the current number of playback processes, it can be determined whether the current display device 200 needs to individually adjust the volume for each window.

According to the traversal result of the playback process, if the number of playback processes is greater than or equal to 2, it is determined that the display device 200 is currently in the multi-window mode, and the multi-windows can output audio signals correspondingly. The controller 250 may perform the step of detecting the current focus window when it is detected that the number of current playing processes is greater than or equal to 2.

If the number of playback processes is less than or equal to 1, it is determined that the display device 200 is not in the multi-window mode or that only one of the multiple windows corresponds to outputting an audio signal. At this time, it is not necessary to perform volume adjustment separately for each window, therefore, the current overall volume of the display device 200 may be acquired to calculate the adjusted volume according to the current overall volume and the volume adjustment amount. Wherein, to obtain the current overall volume of the display device 200, the current overall volume may also be queried in the database according to the method in the above-mentioned embodiment. After obtaining the current overall volume, the adjusted volume is also calculated according to the volume adjustment input by the user, and the gain of the audio output channel of the speaker or the external audio output device is modified according to the adjusted volume to realize the adjustment of the overall volume.

In addition, regardless of whether the overall volume adjustment is performed or the volume adjustment is performed separately for a single window, after setting the overall audio output path gain of the display device 200 or adjusting the audio output path gain of the focus window according to the adjusted volume, the controller 250 can also adjust the adjusted audio output path gain. The volume is recorded, that is, the adjusted volume is recorded to update the database according to the adjusted volume, so that the adjusted volume can be used as the current volume of the next volume adjustment process.

Based on the above-mentioned display device 200, some embodiments of the present application further provide a multi-window audio parameter adjustment method, which is applied to the above-mentioned display device 200. Then, the current focus window can be detected in response to the control instruction. And get the current playback volume of the focused window, and get the volume adjustment amount input by the user. Then calculate the adjusted volume according to the current playback volume and the volume adjustment amount, so as to set the audio output channel gain of the focus window according to the adjusted volume.

As shown in FIG. 13 , it can be known from the above technical solutions that the display device 200 and the multi-window audio parameter adjustment method provided by the above embodiments can first detect the window where the current focus mark is located after acquiring the control command for adjusting the volume, and acquire the focus window. The current playback volume is calculated, and the adjusted volume is calculated in combination with the volume adjustment amount input by the user, so that the audio output channel gain of the focus window is set according to the adjusted volume to complete the volume adjustment. In the method, when the display device 200 is in the multi-window mode, the playback volume in the window can be individually adjusted according to the position of the focus mark, so as to accurately complete the volume adjustment.

The above embodiment can perform separate volume adjustment for the focus window. In some embodiments of the present application, unified volume adjustment is also supported, that is, after the user inputs a control command to adjust the volume, the volume adjustment is performed for all windows synchronously, as shown in FIG. 14 . As shown, the method for synchronously adjusting the volume specifically includes: obtaining a control command input by the user for adjusting the volume; in response to the control command, obtaining the current playback volume of each window, and obtaining the volume adjustment amount input by the user; according to the current playback volume and The volume adjustment amount calculates the adjusted volume separately to set the audio output channel gain of each window according to the adjusted volume.

It can be seen that the difference between this embodiment and the above-mentioned embodiment is that the controller 250 of the display device 200 can obtain the current playback volume of each window at the same time after obtaining the control instruction input by the user, and calculate the volume adjustment volume input by the user separately. Output the adjusted volume of each window, so as to set the volume output channel gain of multiple windows at the same time according to the calculated adjusted volume, realize the adjustment of the corresponding output volume of multiple windows at the same time in one input process, and reduce the repetitive operation of users frequency.

For example, after the user inputs a control command by clicking the volume "-" key on the control device 100, the controller 250 of the display device 200 may, in response to the control command, query the database for the current volume corresponding to the first window and the second window, 25 and 35 respectively. At the same time, the controller 250 can also analyze the volume adjustment amount from the control instruction, that is, the volume adjustment amount corresponding to clicking the volume "-" key is reduced by 10, so it can be calculated that the adjusted volumes of the first window and the second window are respectively 25 -10=15; 35-10=25. Finally, the corresponding volume output channel gains of the first window and the second window are adjusted to 15% and 25% respectively, so that the volume of the first window and the second window can be adjusted at the same time during one operation, so as to avoid the user's second operation.

Based on the above-mentioned display device 200, in some embodiments, a multi-window audio parameter adjustment method is further provided, which is applied to the above-mentioned display device 200. Then, in response to the control instruction, obtain the current playback volume of each window, and obtain the volume adjustment amount input by the user; then calculate the adjusted volume according to the current playback volume and the volume adjustment amount, so as to set each window according to the adjusted volume. gain of the audio output path.

It can be seen that, as shown in Figure 16, the above-mentioned multi-window audio parameter adjustment method can obtain the current playback volume of multiple windows at the same time after obtaining the control command to adjust the volume, and calculate the adjustment of each window separately in combination with the volume adjustment amount input by the user After the volume is adjusted, the audio output channel gain of each window is set according to the adjusted volume to complete the volume adjustment. The method can adjust the playback volume of multiple windows at the same time through one volume adjustment interaction when the display device 200 is in the multi-window mode, so as to accurately complete the volume adjustment, reduce the number of user interactions, and improve user experience.

Similarly, the display device 200 may indicate the volume adjustment process through the volume adjustment control, and change the specific pattern shape along with the volume adjustment process, so as to obtain a better interactive experience. That is, in some embodiments, after acquiring the currently playing audio parameters of each window, the display device 200 can set a parameter adjustment control pattern according to the currently playing audio parameters; and display each parameter adjustment control in the global interface. For example, as shown in FIG. 17 , after inputting a control instruction for adjusting audio parameters, the display device 200 can simultaneously acquire the current playback volume of the two windows, and set the patterns of the two volume adjustment controls according to the current playback volume. And after the user inputs the volume to be adjusted, the patterns of the two volume adjustment controls are modified simultaneously according to the input volume.

In addition to the foregoing volume adjustment methods, the display device 200 may also allow the user to select a window for which volume adjustment is performed through a window after the user inputs a control instruction. That is, as shown in FIG. 15 , in some embodiments, the controller 250 of the display device 200 may control the display to display a window selection interface in response to the control instruction after acquiring the control instruction for adjusting the volume input by the user. After the user selects a window on the window selection interface, the current playback volume of the target window and the volume adjustment amount input by the user are obtained. Finally, the adjusted volume is calculated according to the current playback volume and the volume adjustment amount, so as to set the audio output channel gain of the target window according to the adjusted volume.

It can be seen that the difference between this embodiment and the above embodiments is that after the user inputs a control instruction, the display device 200 can jump to the window selection interface. The window selection interface may include multiple window options. After the user selects any option, the target window can be determined, and the volume adjustment operation can be performed for the target window.

For example, after entering the dual-window mode, the user inputs a control instruction for adjusting the volume by calling the volume setting menu, and the display device 200 may display the window selection interface before displaying the volume adjustment control. Two window options, the first window and the second window, may be included in the window selection interface. The user can control the movement of the focus mark through the direction keys on the control device 100, select the first window and press the "OK" key, at this time it is determined that the first window is the window whose volume needs to be adjusted, that is, the target window. Then, according to the method in the above-mentioned embodiment, the current volume 25 of the first window and the volume adjustment amount input by the user+10 are obtained, and the adjusted volume is calculated as 25+10=35. Therefore, the gain of the audio output path of the first window can be set as: 35%.

Based on the above-mentioned display device 200, some embodiments of the present application further provide a multi-window audio parameter adjustment method. The multi-window audio parameter adjustment method package may first obtain a control instruction for adjusting the volume input by the user, and then respond to the The control instruction controls the display to display a window selection interface for the user to select a target window. Then obtain the current playback volume of the target window, and obtain the volume adjustment amount input by the user, so as to calculate the adjusted volume according to the current playback volume and the volume adjustment amount, so as to set the audio output channel gain of the target window according to the adjusted volume.

As shown in FIG. 18 , it can be seen from the above technical solutions that the display device 200 and the multi-window audio parameter adjustment method provided by the above embodiments can display a window selection interface in the user interface after obtaining the control command for adjusting the volume for the user to select Window for volume adjustment. Then, the adjusted volume is calculated according to the current playback volume of the selected window and the input volume adjustment amount, so as to set the audio output channel gain of each window according to the adjusted volume to complete the volume adjustment. The method can enable the user to select the window for adjusting the volume by himself through the window selection interface, so that the user can accurately adjust the volume for each window.

It should be noted that, for the multiple window audio parameter adjustment methods provided in the above embodiments, suitable volume adjustment methods can be selected according to different usage environments in practical applications. For example, when the multiple windows are all windows for playing media asset images, the method of performing volume adjustment is adopted for the focus window; when the multiple windows are all UI interface windows, the method of adjusting the overall volume of the display device 200 is adopted; When the multiple windows include both the playback window and the UI interface window, a volume adjustment method of selecting according to the window selection interface to adjust the target window is adopted.

In addition to the above-mentioned audio parameter adjustment methods, a specific volume adjustment method can also be determined for the audio signal output mode corresponding to each window in the multi-window mode. For example, when the audio signal of the first window is output through the speaker in the display device 200; and the second window is output through the external audio output device, after obtaining the volume adjustment control instruction input by the user, it can be determined that the audio signal is performed through the local speaker. The outputted first window is the adjusted window, and the current volume of the first window is obtained, and the adjusted volume is calculated in combination with the volume adjustment amount input by the user, so that the volume output channel gain corresponding to the first window is set according to the adjusted volume, and the adjustment is completed. The volume adjustment of the display device 200 is displayed.

With the use process of the user, the display device 200 can also be controlled to exit the multi-window mode. For example, after the user selects a window and presses the OK key, the display device 200 switches from the multi-window mode to the normal mode for display, that is, the displayed content becomes a single-screen display. In the process of exiting the multi-window mode, the display device 200 may also modify the output volume of the display device 200 to the output volume of the corresponding window according to the switched display form.

That is, the display device 200 can obtain the output device and the corresponding volume of the corresponding window from the multi-window mode database according to the user's selection, and refresh the output device and volume of the current window mode when switching to the normal mode. For example, if the user selects the first window with the focus, and presses the "OK" key, the display device 200 is controlled to switch to the normal mode, and the content in the first window is displayed in full screen. Then, obtain the output device Out1 of the first window and the corresponding volume Vol1 from the dual-window mode database, so as to set the output device Out1 and the volume to Vol1 in the single-window mode.

It should be noted that, the multiple windows in the multi-window mode described in the embodiments of the present application may be displayed on the same display 260 of the display device 200 , or may be displayed on different multiple displays 260 . For example, the display device 200 may be a dual-screen smart spot TV, that is, may include a first display and a second display. Wherein, the first display can display a specific user interface as a main screen, and the second display can display a specific interface as a secondary screen. After entering the multi-window mode, the display device 200 may control to display different windows on the first display and the second display respectively, so as to output specific display screen content at the same time. In the case where multiple windows are displayed on different displays, the display device 200 can also adjust the volume of the display device 200 by running the above-mentioned multi-window audio parameter adjustment method to improve user experience.

In addition, the above-mentioned embodiment uses volume adjustment as an example to describe the multi-window audio parameter adjustment process. It should be understood that the adjusted audio parameters are not limited to the above-mentioned volume, but may also be other audio parameters. When the display device 200 is performing the adjustment process of other related audio parameters, the general process of the parameter adjustment method is the same, and the difference is only that for different audio parameters, the parameters executed by the user may be different, or the specific parameter setting methods may be different.

As shown in FIG. 19 , taking the adjustment method in which the audio parameter is the sound effect mode as an example, after the user inputs a control instruction for adjusting the sound effect mode, the display device 200 can also respond to the control instruction, detect the current focus window, and then obtain the focus The current sound effect mode corresponding to the window, for example, the current sound effect mode is "High Resolution Human Voice" mode. Then obtain the sound effect mode input by the user, such as the "3D surround" mode. Since the current sound effect mode is different from the sound effect mode set by the user, the adjusted sound effect mode, that is, the "3D surround" mode, can be calculated according to the current sound effect mode and the sound effect mode set by the user, and then according to the corresponding audio analysis of the "3D surround" mode, Processing method, set the audio output channel to obtain the audio playback effect of "3D Surround" mode.

For the same reason, you can also refer to the corresponding embodiment of the above-mentioned unified volume adjustment method, by obtaining the current sound effect mode of each window and the sound effect mode input by the user, and calculating the adjusted sound effect mode, so as to set each sound effect mode according to the adjusted sound effect mode. sound mode for each window. And, referring to the above-mentioned embodiment of adjusting the volume according to the target window, after inputting the control instruction for adjusting the sound effect mode, a window selection interface is displayed to determine the target window. Then, the adjusted sound effect mode is calculated by acquiring the current sound effect mode of the target window and the new sound effect mode input by the user, thereby adjusting the sound effect mode of the target window to the specified sound effect mode.

Similar parts between the embodiments provided in the present application may be referred to each other. The specific embodiments provided above are just a few examples under the general concept of the present application, and do not constitute a limitation on the protection scope of the present application. For those skilled in the art, any other implementations expanded according to the solution of the present application without creative work fall within the protection scope of the present application.
