For example, as shown in Figure 1(a), it is a schematic diagram of the display screen of the electronic device when the video window is displayed in a small window. The video window displayed in the small window is suspended in a corner of the display screen of the intelligent interactive all-in-one machine, and the intelligent interaction The other area of the display screen of the all-in-one machine is an electronic drawing board, and the user can write on the electronic drawing board by touching the screen or using a stylus pen; among them, the video window is a small window display means: a display in the electronic device Or the video window area formed by multiple video windows only occupies a part of the area of the display screen of the electronic device, but does not occupy the entire area of the display screen of the electronic device.

As shown in Figure 1(b), it is a schematic diagram of the display screen of the electronic device when the video window is displayed in full screen. Among them, multiple video windows are tiled on the display screen of the intelligent interactive all-in-one machine, and occupy the area of the intelligent interactive all-in-one machine. The entire area of the display screen; where the full-screen display of the video window means that the video window area composed of one or more video windows displayed in the electronic device occupies the entire area of the display screen of the electronic device. The video window area formed by the one or more video windows is equivalent to a composite video window synthesized by the one or more video windows, and the window size of the composite video window is the full screen size.

Wherein, in this specific implementation manner, the maximum system resolution of the electronic device may be 4K resolution. The so-called 4K resolution refers to: in the display screen of the electronic device, the number of pixels in each pixel row in the horizontal direction can reach or close to a resolution of 4096.

Determine the window size of the video window;

Adjusting the system resolution of the electronic device to a target system resolution corresponding to the window size;

The picture of the video window is displayed according to the target system resolution corresponding to the window size.

Hereinafter, a method for displaying a video window screen provided by an embodiment of the present application will be described in detail.

FIG. 2 is a schematic flowchart of a method for displaying a video window screen provided by an embodiment of the application. As shown in FIG. 2, the method may include the following steps:

S201: Determine the window size of the video window;

It is understandable that during the process of displaying the video picture in the video window, the electronic device can change the window size of the video window according to various instructions sent by the user to adjust the window size of the video window. Based on this, in order to ensure the display effect of the video screen displayed by the video window under different window sizes, the electronic device may first determine the window size of the video window.

Optionally, the electronic device can display the video window on the display screen in a variety of display modes, and the window size of the video window can be different in different display modes, so that when the display mode of the video window is changed , The window size of the video window can be changed.

In this way, when detecting a change in the display mode of the video window, the electronic device needs to re-determine the window size of the video window, thereby determining whether the system resolution needs to be adjusted.

Among them, the electronic device can determine the window size of the video window in a variety of ways, which is not specifically limited in the embodiment of the present application.

Optionally, in a specific implementation manner, the electronic device may detect the display mode of the video window, so as to determine the window size of the video window according to the detected display mode.

Optionally, in a specific implementation manner, the electronic device can detect the ratio of the area occupied by the video window on the display screen to the entire display screen, so that the size of the video window can be determined according to the ratio and the size of the display screen. The size of the window.

Optionally, in a specific implementation manner, the electronic device may directly detect the length and width dimensions of the video window, and thereby, determine the window size of the video window according to the detected length and width dimensions.

Optionally, in a specific implementation manner, when the electronic device receives the full-screen display instruction, it can determine that the window size of the video window is the full-screen size, and then it can be determined that the window size of the video window is the size of the display screen of the electronic device.

S202: Adjust the system resolution of the electronic device to the target system resolution corresponding to the window size;

After performing the above step S201 and determining the window size of the video window, the electronic device can continue to perform the above step S202 to adjust the system resolution of the electronic device to the target system resolution corresponding to the window size.

S203: Display the picture of the video window according to the target system resolution corresponding to the window size.

After performing the above step S202, the system resolution of the electronic device is adjusted to the target system resolution corresponding to the determined window size, the electronic device can display the picture of the video window according to the target system resolution corresponding to the window size.

Next, the above step S201, determining the window size of the video window, will be specifically described:

According to different display states of the video window in actual applications, the electronic device may execute the above step S201 at different times to obtain the window size of the video window.

Based on this, optionally, in a specific implementation manner, the target system resolution corresponding to the window size may be: under the window size, the system resolution used to ensure that the CPU load of the electronic device meets the target load condition. Furthermore, the above step S201 may include the following steps:

When opening the video window, determine the window size of the video window;

or,

When starting video playback in the video window, determine the window size of the video window;

or,

In the case of obtaining an adjustment instruction for the window from small to large for the video window, the window size of the video window after responding to the adjustment instruction for the window from small to large is determined.

That is to say, in this specific implementation manner, the electronic device can perform the above step S201 in three cases, wherein, in the three cases, the specific implementation manner of the electronic device is as follows:

In the first case, the video window is opened; specifically, in this case, the electronic device can determine the window size of the opened video window when the video window is opened.

A video window can include three processes from the beginning of the display to the end of the display: opening the video window, displaying the video image in the video window, and closing the video window. Obviously, after the video window is opened, the video window starts to display the video image. Therefore, the electronic device needs to refresh and render the video image displayed in the video window in real time. Therefore, when the video window is opened, the electronic device needs to determine whether Need to adjust the system resolution. Based on this, the electronic device can determine the window size of the video window when the video window is opened.

Optionally, the electronic device may preset a default display mode when the video window is opened, that is, preset a display mode used when the video window is started. In this way, the window size of the video window can be directly determined when the video window is opened.

In the second case, video playback is started in the video window; specifically, in this case, the electronic device can determine the window size of the video window when starting video playback in the video window, that is, when the video screen starts to be displayed in the video window To determine the window size of the video window.

It is understandable that in many cases, the video window is opened but the video playback is not started, that is, although there is a video window on the display screen of the electronic device, the video window does not display a video screen, or there is Although there is a video window on the display screen of the electronic device, the video picture displayed in the video window remains unchanged, that is, the video picture played by the video window is in a playback pause state. Then, in this case, although the video window is open, because there is no video screen displayed in the video window, or the played video screen is in a playback pause state, the electronic device does not need to display the video in the video window. The screen is refreshed and rendered in real time. Furthermore, in this case, the electronic device may determine that the system resolution does not need to be adjusted, and therefore, the electronic device may not determine the window size of the video window. Furthermore, when video playback is started in the video window, since the video screen displayed in the video window may continue to change, the electronic device may start to need to refresh and render the video screen displayed in the video window in real time, thus, The electronic device needs to determine whether the system resolution needs to be adjusted. Based on this, when detecting that the video in the video window is started to play, the electronic device can determine the window size of the video window.

In the third case, an adjustment instruction for the window of the video window from small to large is obtained; specifically, in this case, the electronic device first responds to the obtained adjustment instruction, and then determines the result obtained after responding to the adjustment instruction The window size of the video window.

In the process of displaying the video window on the display screen of the electronic device, the user can change the window size of the video window at any time. Among them, when the window size of the video window changes from small to large, after the window size change is completed, when the electronic device refreshes and renders the video screen displayed in the video window in real time, the number of pixels that need to be refreshed and rendered Will increase, and thus, the CPU load of the electronic device will increase accordingly. Based on this, in this case, in order to ensure the display effect of the video screen displayed by the video window, the electronic device needs to adjust the system resolution so that the CPU load can meet the real-time refresh and rendering requirements of the video window. Ensure that the CPU load of the electronic device meets the target load condition. The target load conditions include conditions that enable the CPU load of the electronic device to meet the requirements for real-time refreshing and rendering of the video screen displayed by the video window.

Wherein, optionally, the foregoing target load condition may be: less than a target load threshold; or: within a target load range.

Optionally, the target load threshold includes: the maximum CPU load threshold that the electronic device can bear when meeting the requirements for real-time refreshing and rendering of the video screen displayed in the video window.

Wherein, the target load condition may be a condition preset in the electronic device, and specifically may be less than a preset load threshold, or may be within a preset load range.

Of course, the target load condition can also be other conditions that enable the CPU load of the electronic device to meet the requirements for real-time refreshing and rendering of the video screen displayed by the video window, thereby improving the display effect of the video screen displayed by the video window , This is all reasonable.

In this way, in the case of obtaining the small to large adjustment instruction for the window of the video window, the electronic device can determine the window size of the video window in response to the small to large adjustment instruction of the window.

Optionally, during the video display process, the above-mentioned adjustment instruction for the window of the video window from small to large may be a switch instruction for the video window from small screen display to full screen display.

For example, during a video call, when the user wants to perform local operations in the electronic device, such as writing in an electronic drawing board, the video window currently displayed in full screen can be switched to a small window display; for another example, when the user wants When viewing the expression of the caller in the video screen displayed in the video window more clearly, you can switch the video window currently displayed in the small window to full-screen display.

Obviously, when the video window is switched from small window display to full screen display, the size of the video window will change from small to large, so that the electronic device can determine the window size of the electronic device after the switching is completed.

In this way, in this specific implementation manner, since the target system resolution corresponding to the window size is the system resolution used to ensure that the CPU load of the electronic device meets the target load condition under the window size. Therefore, after adjusting the system resolution of the electronic device to the target system resolution corresponding to the window size of the video window, the electronic device can smoothly refresh and refresh the video screen displayed in the video window in real time under the window size. Rendering, thereby improving the display effect of the video screen displayed in the video window.

Hereinafter, the above step S202 of adjusting the system resolution of the electronic device to the target system resolution corresponding to the window size will be described in detail.

Optionally, in a specific implementation manner, the target system resolution corresponding to the window size may be: under the window size, the system resolution used to ensure that the CPU load of the electronic device meets the target load condition. In this way, after adjusting the system resolution of the electronic device to the target system resolution corresponding to the window size of the video window, the electronic device can smoothly refresh and refresh the video screen displayed in the video window in real time under the window size. Rendering, thereby improving the display effect of the video screen displayed in the video window.

Optionally, when it is determined that the window size of the video window is the same as the size of the display screen of the electronic device, that is, when the window size of the video window is determined to be the full screen, the system resolution of the electronic device can be adjusted It is the target system resolution corresponding to the full screen.

Preferably, the system resolution of the electronic device may be adjusted to the target system resolution corresponding to the full screen only when the window size of the video window is determined to be the full screen.

It should be noted that adjusting the system resolution of an electronic device may cause the operation interface of the electronic device to be deformed. For example, the size of the icon in the operation interface or the aspect ratio of the icon changes, etc., and when it is only in the window size of the video window When adjusting the system resolution for full screen, since the video window occupies the entire area of the display screen of the electronic device, the user can only see the video displayed in the full screen video window, but not The operation interface of the electronic device, therefore, even if the operation interface of the electronic device is deformed due to the adjustment of the system resolution, the user will not perceive it, so that the user experience can be improved.

Optionally, in an embodiment of this specific implementation, as shown in FIG. 3(a), the foregoing step S202 may include the following steps:

S202A: Decrease the system resolution of the electronic device to the target system resolution corresponding to the window size according to the preset correspondence between the window size and the system resolution.

Specifically, when the video windows are in different window sizes, the system resolution that can ensure that the CPU load of the electronic device meets the target load condition can be determined in advance, so that the corresponding relationship between the window size and the system resolution is established, and the corresponding relationship is recorded In electronic equipment. In this way, after the window size of the video window is determined, the electronic device can directly read the target system resolution corresponding to the determined window size from the corresponding relationship.

Optionally, when determining the above-mentioned corresponding relationship, according to the CPU model and various parameters of the electronic device, it can be calculated that when the video window is in different window sizes, it can ensure that the CPU load of the electronic device meets the system resolution of the target load condition. rate;

Optionally, when determining the above-mentioned corresponding relationship, the corresponding relationship between the window size and the system resolution may be determined according to the resolution of the video screen displayed in the video window (or the resolution of the code stream).

Specifically, if the resolution (or stream resolution) of the video screen displayed by the video window is less than the maximum system resolution that the electronic device can provide, you can set: when the window size of the video window reaches the preset size, Determine the resolution (or stream resolution) of the video screen displayed in the video window as the system resolution corresponding to the window size.

Optionally, when the window size of the video window does not reach the aforementioned preset size, the maximum system resolution that the electronic device can provide may be determined as the system resolution corresponding to the window size.

For example, the maximum system resolution that electronic devices such as smart interactive all-in-one machines can provide is 4K resolution, and the video screen resolution in the video window is 1920*1080, which is referred to as 1080P. Then the preset size of the video window can be set to 50% of the display screen size of the above-mentioned smart interactive all-in-one electronic device, so that when the window size of the video window reaches the size of the display screen of the above-mentioned smart interactive all-in-one electronic device When 50%, the system resolution corresponding to the window size of the video window is determined to be 1080P; when the window size of the video window does not reach 50% of the display screen size of the above-mentioned smart interactive all-in-one machine and other electronic devices, the window size of the video window The corresponding system resolution is determined to be 4K resolution.

Optionally, for electronic devices that display video windows including small-screen display and full-screen display, the window size and system resolution are determined according to the resolution (or stream resolution) of the video screen displayed in the video window. For the corresponding relationship of the video rate, the aforementioned preset size may be: the window size of the video window when the video window is displayed in full screen.

That is to say, when the video window is displayed in full screen, the system resolution corresponding to the window size of the video window is determined as: the resolution of the video screen;

When the video window is displayed as a small window, it is determined that the resolution corresponding to the window size of the video window is: the maximum system resolution provided by the electronic device.

For example, the display mode of the video window in the above-mentioned smart interactive all-in-one electronic device includes small screen display and full screen display, you can set: when the display mode of the video window is small screen display, the system corresponding to the window size of the video window The resolution is determined as the initial system resolution of the electronic device or the maximum resolution that the electronic device can provide, such as 4K resolution; when the display mode of the video window is full-screen display, set the system resolution corresponding to the window size of the video window Set as the resolution (or stream resolution) of the video screen displayed in the video window, for example, 1080P.

In this way, when the video window is displayed in full screen, the system resolution of the electronic device is adjusted to the resolution (or stream resolution) of the video screen displayed in the video window. At this time, the resolution of the video screen displayed in the video window does not match It does not drop, but reduces the system resolution of the electronic device, thereby reducing the CPU resources consumed by the electronic device when performing operations such as decoding, refreshing, and rendering the video screen displayed in the video window, and improves the video screen displayed in the video window The smoothness of the video window improves the display effect of the video screen displayed in the video window.

Moreover, when the video window is displayed in full screen, since the video window occupies the entire area of the display screen of the electronic device, the user can only see the video window displayed in full screen, and not the operation interface of the electronic device. In this way, even if the operation interface of the electronic device is deformed due to the adjustment of the system resolution, the user will not perceive it, which can improve the user experience; in addition, the system resolution of the electronic device is reduced only when the video window is displayed in full screen, The maximum system resolution provided by the electronic device can be used when the video window is displayed on a small screen other than the full-screen display, so that when the video window is displayed on a small screen other than the full-screen display, the user can perform other tasks on the electronic device. During operation (for example, writing in the electronic drawing board), you can see a clearer operation screen; at the same time, it can make the operation interface of the electronic device not appear when the video window is displayed on a small screen except the full screen display. The phenomenon of distortion due to resolution.

Optionally, in another embodiment of this specific implementation, as shown in FIG. 3(b), the foregoing step S202 may include the following steps:

S202B: Decrease the system resolution of the electronic device according to the preset resolution adjustment amount until the CPU load of the electronic device meets the target load condition.

In this embodiment, the window size of the video window is when the electronic device opens the video window, or when the video playback is started in the video window, or when the window size adjustment instruction for the video window is obtained from small to large Therefore, in order to ensure that the CPU load of the electronic device meets the target load condition, the system resolution of the electronic device can be reduced.

Specifically, in order to ensure that the CPU load of the electronic device meets the target load condition, the display screen can also have a higher definition, the electronic device can gradually reduce the system resolution of the electronic device according to the preset resolution adjustment amount, until The CPU load of the electronic device satisfies the target load condition.

Optionally, after the system resolution is reduced by the preset resolution adjustment amount each time, the electronic device may calculate the current CPU load of the electronic device and detect whether the CPU load meets the target load condition. Furthermore, when the detection result is yes, stop reducing the system resolution, otherwise, you can adjust the preset resolution again to reduce the system resolution, and repeat the above calculation and detection process until the CPU load of the electronic device meets the target Load conditions.

It is understandable that before the above step S202 is performed to adjust the system resolution of the electronic device to the target system resolution corresponding to the determined window size, the electronic device uses a certain system resolution to display its own display screen. contents.

Based on this, optionally, in a specific implementation manner, before the system resolution of the electronic device is adjusted to the target system resolution corresponding to the determined window size, the system resolution of the electronic device may be the first system resolution The first system resolution may include: the initial system resolution of the electronic device or the maximum system resolution that the electronic device can provide.

Obviously, the initial system resolution of the electronic device may be a system resolution not greater than the maximum system resolution that the electronic device can provide. Of course, the first system resolution may also be other system resolutions besides the aforementioned initial system resolution and maximum system resolution.

Further, after the video window is opened, or the video playback is started in the video window, or, after the video window is adjusted from small to large in response to the adjustment instruction, the display state of the video window can be changed, so that the electronic device You can adjust the system resolution again.

Based on this, in this specific implementation, on the basis of the specific implementation shown in Figures 3(a) and 3(b), as shown in Figures 4(a) and 4(b), this application implements The example provides a method for displaying a video window screen, which may also include the following steps:

S204: Obtain a state change instruction for the video window;

Among them, the state change instruction includes: at least one instruction among the video window restoration instruction, hiding instruction, closing instruction, and window adjustment instruction from large to small; and, the restoration instruction is: used to instruct to restore the window size of the video window to Respond to the instruction of adjusting the size of the window before the instruction from small to large.

S205: Adjust the system resolution of the electronic device to the first system resolution.

Obviously, when the above state change instruction is a restore instruction or a window size adjustment instruction from large to small, the electronic device will reduce the window size of the video window; and when the above state change instruction is a close instruction or a hide instruction, the display screen will The video window is no longer displayed. Based on this, when the state change instruction for the video window is obtained, when the electronic device refreshes and renders the picture displayed in the video window in real time, the number of refreshed and rendered pixels will be reduced, or the electronic device It is no longer necessary to refresh and render the picture displayed in the video window in real time, and therefore, the CPU load of the electronic device will be reduced.

Further, since in this specific implementation, the current system resolution of the electronic device is the system resolution adjusted to after the above step S202 is executed, and according to the above-mentioned specific comparison shown in FIG. 3(a) and FIG. 3(b) Description of the implementation method, the current system resolution of the electronic device can be smaller than the first system resolution of the electronic device. Therefore, in order to improve the definition of the display screen of the electronic device, the electronic device can restore the system resolution to the first system resolution. Resolution.

In particular, when the above-mentioned state change command is a restoration command or a window adjustment command from large to small, after restoring the system resolution of the electronic device to the first system resolution, the display can also be displayed in accordance with the first system resolution. The picture displayed in the video window.

Wherein, in an embodiment of the specific implementation shown in FIG. 4(a) and FIG. 4(b), the electronic device may record the first system resolution of the electronic device before performing step S202 above, so that In this embodiment, the electronic device can directly read the recorded first system resolution of the electronic device after acquiring the state change instruction for the video window, and then execute the above-mentioned step S205.

Optionally, in a specific implementation manner, on the basis of the specific implementation manner shown in Figure 3(a) and Figure 3(b), as shown in Figure 5(a) and Figure 5(b), this application The video window screen display method provided by the embodiment may further include the following steps:

S206: Obtain a window size adjustment instruction for the video window from large to small;

S207: Determine the current window size of the video window after responding to the window adjustment instruction from large to small;

S208: Increase the system resolution of the electronic device to the second system resolution,

Wherein, the second system resolution is: the maximum system resolution used to ensure that the CPU load of the electronic device meets the target load condition under the current window size of the video window.

Specifically, after performing the above step S203, the electronic device can continue to obtain the window size adjustment instruction for the video window from large to small, so that the electronic device can respond to the adjustment instruction to reduce the window size of the video window. Furthermore, the electronic device can determine the current window size of the video window after responding to the window adjustment instruction from large to small.

Among them, the display mode of the video window is first converted from a small screen display to a full screen display or a window display larger than a small screen video window, and then a full screen display or a window display larger than a small screen video window is converted to a small screen display. When the screen is displayed, the instruction acquired by the electronic device may be: a restoration instruction, and the restoration instruction may be a window size adjustment instruction for the video window.

Among them, since the window size of the video window is reduced after responding to the window size adjustment command from large to small, the electronic device performs the operation on the video screen displayed by the video window after responding to the window size adjustment command from large to small. When refreshing and rendering in real time, the number of refreshed and rendered pixels will be smaller. Based on this, the electronic device can increase the system resolution to the second system resolution.

In particular, after the system resolution of the electronic device is increased to the second system resolution, the electronic device may also display the picture of the video window according to the second system resolution.

Optionally, when the video windows are in different window sizes, the maximum system resolution that can ensure that the CPU load of the electronic device meets the target load conditions can be determined in advance, thereby establishing the correspondence between the window size and the second system resolution, and The corresponding relationship is recorded in the electronic device. In this way, after the current window size of the video window after the adjustment instruction of the response window is determined from large to small, the video window after the determined adjustment instruction of the response window from large to small can be directly read from the corresponding relationship. The current window size corresponds to the second system resolution, thereby increasing the system resolution of the electronic device to the second system resolution.

Optionally, the electronic device may gradually increase the system resolution according to a preset resolution adjustment amount until the CPU load of the electronic device does not meet the target load condition, and the difference between the CPU load of the electronic device and the target load threshold is the smallest.

Among them, each time the system resolution is increased according to the preset resolution adjustment amount, the electronic device can calculate the current CPU load of the electronic device and detect whether the difference between the CPU load and the target load threshold is less than the preset resolution adjustment Then, when the detection result is yes, stop reducing the system resolution, otherwise, you can adjust the amount according to the preset resolution again to increase the system resolution, and repeat the above calculation and detection process until the CPU load of the electronic device is not The target load condition is met, and the difference between the CPU load of the electronic device and the target load threshold is the smallest.

In addition, it is understandable that there may be a situation where the window size of the video window is relatively large and the CPU load of the electronic device is still lower than the target load threshold. In this case, the electronic device may not adjust the system resolution.

Based on this, optionally, in a specific implementation manner, as shown in FIG. 6, the video window screen display method provided in the embodiment of the present application may further include the following steps:

S201A: Detect whether the CPU load of the electronic device meets the target load condition; if not, execute the above step S202.

In the embodiment of the present application, after the window size of the video window is determined, the electronic device can further detect whether the CPU load of the electronic device meets the target load condition. For example, detecting whether the CPU load of the electronic device is greater than the target load threshold; for another example, detecting whether the CPU load of the electronic device is within the target threshold range, and so on.

Furthermore, when the detection result is unsatisfactory, in order to ensure the display effect of the video picture displayed by the video window, the electronic device may adjust the system resolution to the target system resolution corresponding to the window size of the video window. Of course, the electronic device may also first detect whether the CPU load is greater than the target load threshold, and when the detection result is yes, determine the window size of the video window, and adjust the system resolution to the target system resolution corresponding to the window size of the video window. In this way, the number of times of adjusting the system resolution can be reduced, thereby reducing the number of times the operation interface of the electronic device is deformed. For the user, the interface layout seen by the user is more stable and the user experience is improved.
