However, with the continuous upgrading of the user interface of the intelligent television, more pictures are required to be displayed in an interaction mode, and meanwhile, the volume of the pictures is larger. Particularly, the home page of the intelligent television uses a large number of pictures to display various recommended films. If the intelligent television front page recommends films according to film types, each type has at least 15 pictures, and at least 3 film types are displayed at a time. Then, according to the picture display method, the intelligent television needs to load at least 45 pictures at a time. If the pictures are loaded at the same time, page blocking is caused, picture loading is slow, even a skylight appears in a page display area, and the user experience effect of the intelligent television is reduced.

Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
In the embodiment of the application, the screen display area of the intelligent television only displays a part of the user interface, and the interface of the intelligent television is a canvas with a size far larger than that of the screen display area of the intelligent television. When the intelligent television receives the interface movement signal to perform interface interaction, the intelligent television can be regarded as the interface interaction, the position of the screen display area of the intelligent television, which is opposite to the user interface, is changed by the movement interface, and then the content which is not positioned in the screen display area of the intelligent television is moved to the screen display area of the intelligent television, so that the content is displayed on the screen display of the intelligent television.
In the embodiment of the application, the plane of the screen of the intelligent television is divided into 3 areas: a viewable area, a preloaded area, and an unloaded area. Fig. 1 is a schematic view of a zoning structure. As shown in fig. 1, region 1 is the viewable area, region 2 is the preloaded area, and region 3 is the unloaded area. The visual area is an area which needs to be displayed on the screen of the intelligent television, is an intuitive visual area for users, and has the same size as the screen of the intelligent television. When a picture on a user interface is located within a viewable area (as long as a point on the picture is located in that area), the picture needs to be loaded directly, and a picture on the user interface in or framed by a frame of that area needs to be loaded. The preloaded area refers to an area beyond the visible area by a certain extent, when the picture on the user interface is located in the preloaded area (as long as a point on the picture is located in the area), the picture on the user interface in the area needs to be directly loaded, i.e. the picture in or framed by the border mine of the area needs to be loaded, because the picture is most likely to be displayed when the user interacts next time. The preloading area can be selected to be an area exceeding any range of each boundary of the visual area, or can be selected to be an area exceeding the equal range of each boundary of the visual area, such as 1.1 times and 1.2 times of each boundary exceeding each boundary of the visual area. Because both the viewable area and the preloaded area need to be loaded, the viewable area and preloaded area may be referred to as loaded areas. The unloaded area refers to an area beyond the preloaded area, and when a picture on the user interface is completely located in the unloaded area, the picture is not loaded.
When the intelligent television receives the interface movement signal, if the position of the user interface of the intelligent television relative to the screen of the intelligent television changes, the region division of the user interface of the intelligent television changes, so that the picture in the unloaded region possibly becomes the picture in the loaded region. The embodiment of the application further provides a picture loading method which is used for effectively controlling the picture loading time sequence of the user interface.
Fig. 2 is a flowchart of a picture loading method provided by an embodiment of the present application, where the picture loading method is mainly used for display devices such as an intelligent television. As shown in fig. 2, the image loading method provided by the embodiment of the present application includes:
s100: traversing a picture queue according to the received interface moving signal, and acquiring boundary coordinates traversed to pictures in the picture queue based on a screen coordinate system of display equipment, wherein the picture queue is used for centrally managing the pictures in the interface.
S200: and judging whether the picture is in the loading area or not according to the boundary coordinates of the picture.
S300: and if the picture is in the loading area, loading the picture.
In the embodiment of the application, in order to facilitate centralized management of pictures in a user interface, a picture queue is set, and the pictures in the interface are centrally managed by the picture queue. When the user interface is opened, the pictures on the user interface are added to the picture queue. The pictures in the queue are loaded under the control of the picture loading method provided by the embodiment of the application. Alternatively, a relatively large volume of pictures may be selected from the user interface to be added to a queue.
And traversing the picture queue when the intelligent television receives the interface moving signal, determining whether each picture in the picture queue is in a loading area, and loading the pictures in the loading area. Specifically, whether each picture in the picture queue is in a recording area is determined, each boundary coordinate of the picture can be obtained based on a screen coordinate system of the display device, and whether the picture is in a loading area is determined according to each boundary coordinate of the picture. Only when the picture exists in the part in the loading area, the picture is in the loading area, and then the picture is loaded.
In the embodiment of the application, the interface movement signals comprise signals which can cause the user interface to move relative to the screen position of the display device by opening a new page, pressing a key on a remote controller and the like. Preferably, the interface movement signal includes a signal to open a new page and to press a direction key on the remote controller. When the display equipment receives a signal for opening a new page or pressing a direction key on the remote controller, the picture queue is facilitated, the picture to be loaded is determined, and the picture is loaded.
Because the loading area only comprises the visible area and the preloading area, only a part of the user interface is needed to load a part of pictures on the user interface even when the user interface is opened for the first time, and only more than ten pictures are possible, compared with the process of loading hundreds of pictures on the user interface at one time, the bandwidth occupation is reduced when the pictures are loaded, the memory of the display equipment is reduced when the pictures occupy, and the performance of the display equipment is saved. Meanwhile, when the interface movement signal is received, the pictures are dynamically loaded according to the movement condition of the user interface, so that the number of the pictures loaded each time is relatively small, the completion of loading is facilitated, and meanwhile, the performance of the display equipment is saved.
According to the picture loading method provided by the embodiment of the application, in the process of opening a new page, moving a direction key and the like to generate relative position change of a user interface, traversing a picture queue according to a received interface moving signal, acquiring boundary coordinates of pictures in the picture queue at the current moment based on a screen coordinate system of display equipment, and judging whether each picture in the picture queue is in a loading area according to the boundary coordinates of each picture. The loading area refers to that when the whole picture is located in the area or part of the picture is located in the area, the picture needs to be loaded, and when the whole picture is located outside the loading area, the picture does not need to be loaded. Therefore, when the picture is judged to be in the loading area according to the boundary coordinates of the picture, the picture is loaded. According to the picture loading method provided by the embodiment of the application, the pictures are divided into the loading area and the area outside the loading area, and whether the pictures need to be loaded is determined by determining whether the pictures are in the loading area, so that effective control of picture loading time sequence in a user interface is realized, further, dynamic loading of each picture in the user interface according to the specific position of page display is realized, the television performance is saved, the loading efficiency of the pictures in the display area is ensured, and the user experience effect of the intelligent television is improved.
Fig. 3 is a schematic structural diagram of a screen coordinate system of a display device according to an embodiment of the present application, where a solid line box is a screen outline of the display device and a dotted line box is a user interface outline. As shown in fig. 3, the screen coordinate system takes the left vertex of the display device screen as an origin O, takes the direction of the upper boundary of the display device screen away from the origin as the positive direction of the x-axis, and takes the direction of the left boundary of the display device screen away from the origin as the positive direction of the y-axis.
When the user interface is just opened, the top left corner vertex of the user interface coincides with the origin of the screen coordinate system, and when the display device receives the interface movement signal, the position of the user interface changes relative to the screen coordinate system as shown in fig. 4. When the position of the user interface changes relative to the screen coordinate system, the position of the picture on the user interface in the screen coordinate system changes, and therefore the coordinates of the picture on the user interface in the screen coordinate system also change. Therefore, when the display device receives the interface movement signal and determines whether the picture on the user interface needs to be loaded or not according to the coordinates of each boundary of the picture, the coordinates of each boundary of the picture change at the current moment need to be determined again.
When the display device receives the interface moving signal, traversing the picture queue, projecting the traversed picture in a screen coordinate system of the display device, and acquiring coordinates of each boundary of the traversed picture based on the screen coordinate system of the display device. In the embodiment of the application, the boundaries of the picture refer to the outer contour of the picture, so the coordinates of the boundaries of the picture refer to the coordinates of the contours of the top, bottom, left and right of the picture. In the embodiment of the present application, the shape of the picture is generally regular, such as rectangle, square, etc., so that each boundary of the picture includes a top boundary, a bottom boundary, a left boundary, and a right boundary of the picture.
In the image loading method provided by the embodiment of the application, each boundary coordinate traversing to an image in an image queue is obtained based on a screen coordinate system of display equipment, and the method specifically comprises the following steps: and projecting the traversed picture into a screen coordinate system of display equipment, and acquiring a top ordinate, a bottom ordinate, a left boundary abscissa and a right boundary abscissa of the picture in the screen coordinate system.
And when judging whether the picture is in the loading area according to the coordinates of each boundary of the picture, determining whether the coordinates of each boundary of the picture are in the range of the coordinates of the loading area. Optionally, determining whether the top ordinate is within the loading region ordinate interval, whether the bottom ordinate is within the loading region ordinate interval, whether the left boundary abscissa is within the loading region abscissa interval, or whether the right boundary abscissa is within the loading region ordinate interval; when one of the pieces is satisfied, the picture is in the loading area.
In order to facilitate determination of the loading area and determination of whether the picture is in the loading area, in the embodiment of the present application, it is preferable that the preloaded area and each boundary of the preloaded area are equally proportioned to be located beyond the visible area. If each boundary of the preloaded area exceeds each boundary of the corresponding visible area by 1.1 times, that is, the distance between the boundary of the preloaded area and the corresponding boundary of the visible area is 0.1 times the length of the corresponding boundary of the visible area, that is, when the length in the X-axis direction and the length in the Y-axis direction of the visible area are X and Y, the distance between the upper boundary of the preloaded area and the upper boundary of the visible area is 0.1Y, the distance between the lower boundary of the preloaded area and the lower boundary of the visible area is 0.1Y, the distance between the left boundary of the preloaded area and the left boundary of the visible area is 0.1X, and the distance between the right boundary of the preloaded area and the right boundary of the visible area is 0.1X. When the equal proportion of the distance between the boundaries of the preloaded area exceeds the visible area, the proportion is called a loading coefficient, the loading coefficient is more than or equal to 1, and the loading coefficient is more than 1. If each boundary of the preloaded area exceeds each corresponding boundary of the viewable area by 1.1 times, then 1.1 is its loading coefficient.
Therefore, in the image loading method provided by the embodiment of the present application, according to the coordinates of each boundary of the image, whether the image is in the loading area is determined, which specifically includes: judging whether the top ordinate is smaller than the screen height by a loading coefficient, whether the bottom ordinate is larger than the screen height by a loading coefficient (1), whether the left border abscissa is smaller than the screen width by a loading coefficient and whether the right border abscissa is larger than the screen width by a loading coefficient (1);
when the top ordinate is less than the screen height loading factor, the bottom ordinate is greater than the screen height (1-loading factor), the left border abscissa is greater than the screen width (1-loading factor), and the right border abscissa is greater than the screen width (1-loading factor), then the picture is in the loading region.
The screen height corresponds to the maximum vertical coordinate value of the screen boundary of the display device in the positive direction of the y axis, and the screen width corresponds to the maximum horizontal coordinate value of the screen boundary of the display device in the positive direction of the x axis. When the coordinates of all boundaries of the picture are corresponding to meet the judgment logic, the picture is in the loading area.
Optionally, the specific execution logic is as follows:
this.rect.top<window.innerHeight*this.options.preLoad&&
this.rect.bottom>window.innerHeight*(1-this.options.preLoad)&&
this.rect.left<window.innerWidth*this.options.preLoad&&
this.rect.right>window.innerWidth*(1-this.options.preLoad)
wherein: innerHeight is the screen height, innerWidth is the screen width, top is the top ordinate of the picture, bottom is the bottom ordinate of the picture, left is the left border abscissa of the picture, right is the right border abscissa of the picture, this.
In the embodiment of the application, if the number of the pictures in the picture queue is relatively large, when the user frequently operates the display device again, the display device frequently receives the interface moving signal once by one time, and the display device controller is to traverse the picture queue to execute the judgment of whether the pictures in the picture queue need to be loaded or not and record the pictures meeting the loading condition. Such as when the user holds down a directional key to move the page, the page switches quickly. Each time of switching is to be executed to traverse the picture queue to judge whether the pictures in the picture queue need to be loaded, however, loading the pictures skipped in the middle of switching is meaningless, and waste of network resources is caused.
Or when a new user interface is opened, the user interface comprises a plurality of pictures, so that a plurality of pictures need to be loaded in the process of displaying the user interface, and each time the pictures are loaded, the picture queue is traversed once to judge whether the pictures in the picture queue need to be loaded or not and the pictures meeting the loading conditions need to be loaded. If a user interface has n pictures, opening the page will be performed n times to determine whether the pictures in the picture queue need to be loaded with the core algorithm, and the loading logic n-! And (5) secondary judgment. But in this case, it is totally meaningless to perform the previous n-1 runs of determining whether the pictures in the picture queue need to load the core algorithm, (n-1) +.! The secondary load logic is meaningless. Since the previous n-1 times are fully covered at the nth time.
And when the two conditions happen simultaneously, more meaningless calculation loading can be generated in the middle, so that the performance of the display equipment and the network resources are wasted.
In order to solve the above problems, in the image loading method provided by the embodiment of the present application, the image queue is traversed according to the received interface movement signal, which specifically includes: receiving an interface movement signal, and monitoring the time of receiving the interface movement signal;
acquiring a time interval between the current received interface movement signal and the last received interface movement signal;
if the time interval between the current received interface movement signal and the last received interface movement signal is greater than or equal to a first time threshold value, traversing the picture queue;
if the time interval between the current received interface movement signal and the last received interface movement signal is smaller than a first time threshold, judging whether the interface movement signal is received within the first time threshold after the current received interface movement signal;
if the interface movement signal is received within the first time threshold time after the interface movement signal is received currently, skipping traversing the picture queue;
if the interface movement signal is not received within the first time threshold time after the interface movement signal is currently received, traversing the image queue at the moment of isolating the first time threshold of the interface movement signal from the current reception.
Therefore, the method and the device can determine whether to execute traversing of the picture queue or not by monitoring the time interval between two adjacent received interface movement signals, and judge whether the pictures in the picture queue need to be loaded or not. Monitoring the time interval between two adjacent received interface moving signals, and executing traversing the image queue when the time interval between the current received interface moving signal and the last received interface moving signal is greater than or equal to a first time threshold; when the time interval between the current received interface moving signal and the last received interface moving signal is smaller than a first time threshold, skipping the image queue to be executed, until the interface moving signal is not received within the first time threshold time after the current received interface moving signal, and traversing the image queue at the moment of the first time threshold of the current received interface moving signal.
For example, when the time interval for the user to frequently operate the display device is 50ms, the first time threshold may be 200ms, and fig. 5 is a schematic diagram of specific implementation. As shown in fig. 5, therefore, when the user frequently operates the display device, the display device frequently receives the interface movement signals, determines the time interval between each interface movement signal and the corresponding previous interface movement signal, and traverses the picture queue to determine whether the pictures in the picture queue need to be loaded or not and load the pictures meeting the loading condition when the interval is greater than 200ms or 200ms after the frequently receiving of the interface movement signals, so that the controller will execute the traversing the picture queue to determine whether the pictures in the picture queue need to be loaded or not and load the pictures meeting the loading condition only after the user operation time interval is greater than or equal to 200ms or the frequent operation is stopped for 200 ms.
In addition, in order to solve the above problem, in the image loading method provided by the embodiment of the present application, traversing the image queue according to the received interface movement signal may further specifically include: receiving an interface movement signal, and monitoring the time of receiving the interface movement signal;
acquiring a time interval between the current received interface movement signal and the last received interface movement signal;
if the time interval between the current received interface movement signal and the last received interface movement signal is smaller than a second time threshold value, acquiring the time of last execution of traversing the image queue;
judging whether the time interval between the current time and the time of last execution of traversing the picture queue is larger than a second time threshold value or not;
and if the time interval between the time of the currently received interface moving signal and the time of the last execution of traversing the picture queue is greater than a second time threshold, executing traversing the picture queue.
Therefore, whether the image queue is traversed at this time or not is determined by monitoring the time interval between two adjacent received interface moving signals and the time of traversing the image queue last time, and whether the image in the image queue needs to be loaded or not is judged. Monitoring the time interval between two adjacent interface moving signals, when the time interval between the current interface moving signal and the last interface moving signal is smaller than a second time threshold, acquiring the time of traversing the picture queue last time, judging whether the time interval between the time of the current received interface moving signal and the time of traversing the picture queue last time is larger than the second time threshold, and if the time interval between the time of the current received interface moving signal and the time of traversing the picture queue last time is larger than the second time threshold, executing traversing the picture queue, judging whether the pictures in the picture queue need to be loaded and the pictures meeting the loading condition are loaded; otherwise, skipping the corresponding traversal picture queue of the currently received interface movement signal.
For example, when the time interval between the current receiving of the interface movement signal and the last receiving of the interface movement signal by the user's fast and frequent operation of the display device is 50ms or when the time interval between the user's fast and frequent operation of the display device is 50ms, the second time threshold may be 200ms, and fig. 6 is a specific implementation schematic diagram. As shown in fig. 6, when the user operates the display device rapidly and frequently, the display device receives each interface movement signal, obtains the time of traversing the picture queue last time, and when the interval between the time of currently received interface movement signal and the time of traversing the picture queue last time is greater than 200ms, the controller judges whether the picture in the picture queue needs to be loaded or not and loads the picture meeting the loading condition by executing the traversing picture queue.
Further, in the image loading method provided by the embodiment of the present application, if the image is in the loading area, after loading the image, the method further includes:
if the picture is loaded successfully, setting the state of the picture as successful loading;
if the picture fails to be loaded, the state of the picture is set as loading failure.
After the picture loading is executed, adding the state of the picture in the picture queue according to the success or failure of the picture loading, setting the state of the picture in the picture queue as the success of the loading when the picture loading is successful, and setting the state of the picture in the picture queue as the failure of the loading when the picture loading is failed. Therefore, the monitoring of the picture transition state in the picture queue is convenient to realize.
Further, in the image loading method provided by the embodiment of the present application, if the image loading fails, the image status is set as the loading failure, which specifically includes:
if the picture loading fails, reloading the picture according to the number of times of automatic reloading trial;
and if the picture is reloaded by automatically attempting the reloading times, the picture fails to be loaded, and the picture is skipped.
In the embodiment of the application, the number of times of automatically attempting reloading is not suitable to be set too large.
