Technical Field
The application relates to the technical field of internet, in particular to a picture loading method and an intelligent television.
Background
The smart television is a new product formed based on internet wave impact, aims to bring more convenient experience to users, and has become the trend of televisions at present. With the popularization of smart televisions, smart televisions have gradually become indispensable listening trial entertainment tools for most families. The intelligent television provides the user with the audition experience which cannot be compared with the mobile small-screen terminal by the unique large-screen terminal attribute.
The user interface of the smart television usually shows the rich and colorful use resources of the smart television in the form of display pictures. Therefore, in the use of the smart television, many pictures need to be loaded and displayed. Generally, the picture link is directly assigned to the picture component for displaying the picture, and the picture component downloads the picture immediately after taking the picture link and then renders the display. When the number of the pictures is small and the size of the pictures is small, the method for displaying the pictures can smoothly complete the display of the pictures of the user interface.
However, with the continuous upgrade of the smart television user interface, more and more pictures need to be displayed for interaction, and the size of the pictures is larger and larger. Especially, the smart television home page uses a large number of pictures to show various recommended movies. For example, the smart television front page recommends movies according to movie types, each type has at least 15 pictures, and at least 3 movie types are shown each time. Then, the pictures are displayed according to the above picture display method, and the smart television needs to load at least 45 pictures at a time. If the pictures are loaded at the same time, the page is blocked, the pictures are loaded slowly, and even a skylight appears in a page display area, so that the user experience effect of the smart television is reduced.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the embodiment of the application, the display area of the screen of the smart television only displays a part of the user interface, and the interface of the smart television is a canvas with a size far larger than the display area of the screen of the smart television. When the intelligent television receives the interface moving signal to perform interface interaction, the position of the intelligent television screen display area facing the user interface is changed by moving the interface during the interface interaction, and the content which is not located in the intelligent television screen display area before is moved to the intelligent television screen display area, so that the content is displayed on the intelligent television screen.
In the embodiment of the application, the plane where the smart television screen is located is divided into 3 areas: a visible area, a preloaded area, and an unloaded area. Fig. 1 is a schematic diagram of a region division structure. As shown in fig. 1, area 1 is a visible area, area 2 is a preloaded area, and area 3 is an unloaded area. The visual area is an area which needs to be displayed on the screen of the intelligent television, is a visual area for a user, and has the same size as the screen of the intelligent television. When a picture on the user interface is located in a visible area (as long as a point on the picture is located in the area), the picture needs to be directly loaded, and a picture in a frame or on the user interface framed by the area needs to be loaded. The preloaded area refers to an area beyond a certain range of the visible area, and 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 is likely to be displayed at the next interaction of the user, so that the picture on the user interface located in the area needs to be directly loaded, that is, the picture in or framed by the border of the area needs to be loaded. The preloading area can be selected as an area exceeding any range of each boundary of the visual area, or an area with each boundary exceeding equal range of each corresponding boundary of the visual area, for example, the range of each boundary exceeding 1.1 times, 1.2 times and the like of each corresponding boundary of the visual area. Because both the visual area and the preload area need to be loaded, the visual area and the preload area may be referred to as a load area. The unloaded area refers to an area beyond the preloaded area, and when the picture on the user interface is completely located in the unloaded area, the picture cannot be loaded.
When the smart television receives the interface moving signal, if the user interface of the smart television changes relative to the screen position of the smart television, the area division of the user interface of the smart television changes, so that the picture in the non-loading area may be changed into the picture in the loading area. Further, the embodiment of the present application provides a picture loading method, which is used for implementing effective control of a user interface picture loading time sequence.
Fig. 2 is a flowchart of a picture loading method according to an embodiment of the present application, where the picture loading method is mainly used for display devices such as a smart television. As shown in fig. 2, the image loading method provided in the embodiment of the present application includes:
s100: traversing the picture queue according to the received interface moving signal, and acquiring each boundary coordinate of the pictures traversed in the picture queue based on a screen coordinate system of the display equipment, wherein the picture queue is used for centrally managing the pictures in the interface.
S200: and judging whether the picture is in a loading area or not according to each boundary coordinate of the picture.
S300: and if the picture is in the loading area, loading the picture.
In the embodiment of the application, a picture queue is arranged to facilitate centralized management of pictures in a user interface, and the pictures in the interface are managed in a centralized mode through 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. Optionally, a relatively large volume of pictures may be selected from the user interface to be added to a queue.
When the smart television receives an interface moving signal, traversing the picture queue, 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 the recording area is determined, boundary coordinates of the pictures can be acquired based on a screen coordinate system of the display device, and whether the pictures are in the loading area is determined according to the boundary coordinates of the pictures. And only when the part of the picture in the loading area exists, the picture is in the loading area, and then the picture is loaded.
In the embodiment of the application, the interface moving signal includes a signal which can cause the user interface to move relative to the screen position of the display device when a new page is opened, a key on a remote controller is pressed, and the like. Preferably, the interface moving signal includes a signal to open a new page and press a direction key on the remote controller. When the display equipment receives a signal of opening a new page or pressing a direction key on the remote controller, the picture queue is facilitated, pictures needing to be loaded are determined, and the pictures are loaded.
Because the loading area only comprises the visual area and the preloading area and is only a part of the user interface, even when the user interface is opened for the first time, only a part of pictures on the user interface need to be loaded, perhaps only dozens of pictures, and compared with the method for loading dozens of hundreds of pictures on the user interface at one time, the method reduces the bandwidth occupation when the pictures are loaded, reduces the memory occupied by the pictures on the display equipment, and saves the performance of the display equipment. Meanwhile, when an interface moving signal is received, the pictures are dynamically loaded according to the moving condition of the user interface, the number of the loaded pictures is relatively small, the loading is convenient to finish, 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 generating the relative position change of the user interface by opening a new page, moving a direction key and the like, the picture queue is traversed according to the received interface moving signal, the boundary coordinates of the pictures in the picture queue are obtained at the current moment based on the screen coordinate system of the display device, and whether each picture in the picture queue is in the loading area is judged according to the boundary coordinates of each picture. The loading area means that when the picture is located in the area completely or partially, the picture needs to be loaded, and when the picture is located outside the loading area completely, the picture does not need to be loaded. Therefore, when the picture is judged to be in the loading area through each boundary coordinate of the picture, the picture is loaded. According to the picture loading method provided by the embodiment of the application, the picture is divided into the loading area and the picture outside the loading area, whether the picture needs to be loaded is determined by determining whether the picture is in the loading area, so that the picture loading time sequence in the user interface is effectively controlled, each picture in the user interface is dynamically loaded according to the specific position displayed on the page, the television performance is saved, the loading efficiency of the picture in the display area is ensured, and the user experience effect of the smart television is improved.
Fig. 3 is a schematic structural diagram of a screen coordinate system of a display device provided in an embodiment of the present application, where a solid line box is a screen outline of the display device, and a dashed 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 the origin O, the direction in which the upper boundary of the display device screen deviates from the origin as the positive direction of the x-axis, and the direction in which the left boundary of the display device screen deviates from the origin as the positive direction of the y-axis.
When the user interface is just opened, the vertex at the upper left corner of the user interface coincides with the origin of the screen coordinate system, as shown in fig. 4, and when the display device receives the interface movement signal, the position of the user interface changes relative to the screen coordinate system. When the position of the user interface relative to the screen coordinate system changes, the position of the picture on the user interface in the screen coordinate system changes, so that the coordinates of the picture on the user interface in the screen coordinate system also changes. Therefore, when the display device receives the interface movement signal and determines whether the picture on the user interface needs to be loaded according to the coordinates of each boundary of the picture, the coordinates of the boundary changed from the picture at the current moment need to be determined again.
When the display equipment receives the interface moving signal, the picture queue is traversed, the traversed pictures are projected in a screen coordinate system of the display equipment, and coordinates of each boundary of the traversed pictures are obtained based on the screen coordinate system of the display equipment. In the embodiment of the present application, the boundaries of the picture refer to the outer contours of the picture, and thus the coordinates of each boundary of the picture refer to the coordinates of the contours of the top, bottom, left, and right portions of the picture. In the embodiment of the present application, the shape of the picture is 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 picture loading method provided in the embodiment of the present application, each boundary coordinate traversing to pictures in a picture queue is obtained based on a screen coordinate system of a display device, and the method specifically includes: and projecting the traversed picture to a screen coordinate system of the 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 coordinate interval of the loading area. Optionally, determining whether the top ordinate is within the range of the loading area ordinate interval, whether the bottom ordinate is within the range of the loading area ordinate interval, and whether the left boundary abscissa is within the range of the loading area abscissa interval or the right boundary abscissa is within the range of the loading area ordinate interval; and when one of the parameters is satisfied, the picture is in the loading area.
In order to facilitate the determination of the loading area and the determination of whether the picture is in the loading area, in the embodiment of the present application, it is preferable that the distances of the preloading area equal to the boundaries exceed the visible area. For example, each boundary of the preload region exceeds each corresponding boundary of the visual region by 1.1 times, that is, the distance between the boundary of the preload region and the corresponding boundary of the visual region is 0.1 times the length of the corresponding boundary of the visual region, that is, when the length of the visual region in the X-axis direction is X and the length of the visual region in the Y-axis direction is Y, the distance between the upper boundary of the preload region and the upper boundary of the visual region is 0.1Y, the distance between the lower boundary of the preload region and the lower boundary of the visual region is 0.1Y, the distance between the left boundary of the preload region and the left boundary of the visual region is 0.1X, and the distance between the right boundary of the preload region and the right boundary of the visual region is 0.1X. When the distances of the preloading region parts at equal proportions exceed the visual region, the proportions are called loading coefficients, the loading coefficients are more than or equal to 1, and the loading coefficients are preferably more than 1. If each boundary of the preloaded region exceeds the corresponding boundary of the visible region by 1.1 times, then 1.1 is its loading factor.
Therefore, in the image loading method provided in the embodiment of the present application, determining whether the image is located in the loading area according to the coordinates of each boundary of the image specifically includes: judging whether the top ordinate is smaller than the screen height loading coefficient, whether the bottom ordinate is larger than the screen height (1-loading coefficient), whether the left boundary abscissa is smaller than the screen width loading coefficient and whether the right boundary abscissa is larger than the screen width (1-loading coefficient);
and when the top ordinate is smaller than the screen height loading coefficient, the bottom ordinate is larger than the screen height (1-loading coefficient), the left boundary abscissa is the screen width loading coefficient, and the right boundary abscissa is larger than the screen width (1-loading coefficient), the picture is positioned in the loading area.
The screen height corresponds to the maximum ordinate 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 abscissa value of the screen boundary of the display device in the positive direction of the x axis. And when the coordinates of all the boundaries of the picture correspondingly 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, and this.
In the embodiment of the application, if the number of the pictures in the picture queue is large, when the user frequently operates the display device, one time of the frequent operation of the user causes the display device to frequently receive one interface moving signal, and the display device controller is to traverse the picture queue to judge whether the pictures in the picture queue need to be loaded and record the pictures meeting the loading condition. For example, when the user presses the direction key to move the page, the page is switched quickly. In each switching, the picture queue is traversed to execute and judge whether the pictures in the picture queue need to be loaded, however, the pictures skipped in the middle of the loading and switching are meaningless, and the 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 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 are loaded every time the pictures are loaded. If a user interface has n pictures, opening the page will execute n times to determine whether the pictures in the picture queue need to load the core algorithm, execute the load logic n! And (5) judging. But in this regard, it makes no sense at all to have the first n-1 executions determine whether the pictures in the picture queue need to load the kernel algorithm (n-1)! The secondary load logic is meaningless. Since the first n-1 times are fully covered at the nth time.
When the two situations happen simultaneously, more meaningless computation loads are generated in the middle, and the performance of the display device and the network resources are wasted.
In order to solve the above problem, in the picture loading method provided in the embodiment of the present application, traversing the picture queue according to the received interface moving signal specifically includes: receiving an interface moving signal, and monitoring the time of receiving the interface moving signal;
acquiring a time interval between the current received interface moving signal and the last received interface moving signal;
traversing the picture queue if the time interval between the currently received interface moving signal and the last received interface moving signal is greater than or equal to a first time threshold;
if the time interval between the currently received interface moving signal and the last received interface moving signal is smaller than a first time threshold, judging whether the interface moving signal is received within the first time threshold after the currently received interface moving signal;
skipping traversing the picture queue if the interface moving signal is received within a first time threshold time after the interface moving signal is currently received;
and traversing the picture queue at the moment of the interval of the first time threshold of the currently received interface moving signal if the interface moving signal is not received within the first time threshold of the currently received interface moving signal.
Therefore, whether the picture queue is traversed or not is determined by monitoring the time interval between two adjacent received interface moving signals, and whether the pictures in the picture queue need to be loaded or not is judged. Monitoring the time interval between two adjacent received interface moving signals, and executing traversing picture queues 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; and when the time interval between the current reception of the interface moving signal and the previous reception of the interface moving signal is smaller than a first time threshold, skipping the traversal picture queue required to be executed this time until the interface moving signal is not received within the first time threshold after the current reception of the interface moving signal, and traversing the picture queue at the moment of the interval of the first time threshold of the current reception of the interface moving signal.
For example, when the time interval for the user to operate the display device rapidly and frequently is 50ms, the first time threshold may be 200ms, and fig. 5 is a specific implementation diagram. As shown in fig. 5, therefore, when the user operates the display device quickly and frequently, the display device receives the interface moving signals frequently, determines the time interval between each interface moving signal and the corresponding previous interface moving signal, and the time interval is greater than 200ms or 200ms after the interface moving signals are received frequently, the controller executes the traversal of the picture queue to determine whether the pictures in the picture queue need to be loaded and the pictures meeting the loading condition are loaded, so that only after the time interval of the user operation is greater than or equal to 200ms or the frequent operation is stopped for 200ms, the controller executes the traversal of the picture queue to determine whether the pictures in the picture queue need to be loaded and the pictures meeting the loading condition are loaded.
In addition, to solve the above problem, in the picture loading method provided in the embodiment of the present application, traversing the picture queue according to the received interface moving signal may further include: receiving an interface moving signal, and monitoring the time for receiving the interface moving signal;
acquiring a time interval between the current received interface moving signal and the last received interface moving signal;
if the time interval between the currently received interface moving signal and the last received interface moving signal is smaller than a second time threshold, acquiring the time for traversing the picture queue last time;
judging whether the time interval between the current time and the time of executing traversing the picture queue last time is greater than a second time threshold value or not;
and executing traversing the picture queue if the time interval between the time of the currently received interface moving signal and the time of executing traversing the picture queue last time is greater than a second time threshold.
Therefore, whether the traversal picture queue is executed or not is determined by monitoring the time interval between the two adjacent received interface moving signals and the time of executing the traversal picture queue last time, and whether the pictures in the picture queue need to be loaded or not is judged. Monitoring the time interval between two adjacent received interface moving signals, when the time interval between the current received interface moving signal and the last received interface moving signal is smaller than a second time threshold, acquiring the time for traversing the picture queue last time, judging whether the time interval between the current received interface moving signal time and the last executed image queue time is larger than the second time threshold, if the time interval between the current received interface moving signal time and the last executed image queue time is larger than the second time threshold, executing the traversing picture queue, and judging whether the pictures in the picture queue need to be loaded and whether the pictures meeting the loading condition need to be loaded; otherwise, skipping the traversing picture queue corresponding to the currently received interface moving signal.
For example, when the time interval between the current reception of the interface movement signal and the last reception of the interface movement signal by the user operating the display device quickly and frequently is 50ms or when the time interval between the current reception of the interface movement signal and the last reception of the interface movement signal by the user operating the display device quickly and frequently is 50ms, the second time threshold may be 200ms, and fig. 6 is a specific implementation diagram. As shown in fig. 6, when the user operates the display device quickly and frequently, the display device receives each interface movement signal, obtains the time for executing the traversal of the picture queue last time, and when the interval between the time for receiving the interface movement signal and the time for executing the traversal of the picture queue last time is greater than 200ms, the controller will execute the traversal of the picture queue to determine whether the pictures in the picture queue need to be loaded and load the pictures meeting the loading condition.
Further, in the method for loading an image provided in the embodiment of the present application, if the image is located in the loading area, after the image is loaded, the method further includes:
if the picture is loaded successfully, setting the state of the picture as loading success;
and if the picture loading fails, setting the state of the picture 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 image state transition in the image queue is convenient to realize.
Further, in the image loading method provided in the embodiment of the present application, if the image loading fails, setting the state of the image as loading failure specifically includes:
if the picture loading fails, reloading the picture according to the automatic trial reloading times;
and if the picture is reloaded by automatically trying the reloading times, the picture loading fails, and the picture is skipped.
In the embodiment of the present application, the number of times of automatic reloading attempts is not set to be too large.
