Detailed Description

The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and/or" as used herein is meant to encompass any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used in the embodiments of the present application to describe various information, the information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present application. Depending on the context, moreover, the word "if" is used may be interpreted as "at … …" or "at … …" or "in response to a determination".

The data display method provided in the embodiment of the application can be applied to data display equipment, and the data display equipment can be any type of equipment, such as a personal computer, a server, terminal equipment, a decoder and the like. Referring to fig. 1, a schematic flow chart of the data display method is shown, and the method may include:

step 101, obtaining first layout information of an original window.

For convenience of distinction, the initial layout information is referred to herein as first layout information, and a window determined based on the first layout information is referred to as an original window, which is not limited to this first layout information.

For example, the mode of the display screen may be an even layout mode and a free layout mode, the even layout mode indicates that the display screen is divided into a plurality of windows on average, and for example, the first layout information may include a number M of horizontal windows and a number N of vertical windows, indicating that the display screen is divided into M × N windows on average. In summary, the first layout information may include a number M of horizontal windows and a number N of vertical windows, where M is a positive integer greater than 1, and N is a positive integer greater than 1, and values of M and N are not limited to these values. M represents that M windows exist in the transverse direction of the display screen, and N represents that N windows exist in the longitudinal direction of the display screen.

Illustratively, the free layout mode represents that a plurality of windows are arbitrarily divided on the display screen, rather than dividing the plurality of windows on average, for example, the first layout information may include the number of windows of the original windows, the vertex coordinates (such as the upper left corner coordinate, the upper right corner coordinate, the lower left corner coordinate, the lower right corner coordinate, the center point coordinate, etc., and the upper left corner coordinate is taken as an example in the following), the initial width and the initial height of each original window. Obviously, based on the vertex coordinates, initial width and initial height of the original window, an original window can be determined. Since the first layout information includes the vertex coordinates, the initial width and the initial height of the original windows of the number of windows, the original windows of the number of windows can be determined based on the first layout information.

102, determining second layout information of the target window based on the first layout information, the number of horizontal reference pixels and the number of vertical reference pixels supported by a decoder; for example, the second layout information may include the number of windows of the target window, and the width and height of each target window.

For convenience of distinction, the final layout information is referred to as the second layout information, and a window determined based on the second layout information is referred to as a target window, which is not limited to the second layout information.

Illustratively, the number of horizontal reference pixels supported by the decoder refers to the number of horizontal pixels that are output by the decoder at least at one time, and the number of horizontal reference pixels is denoted as baseX. The number of vertical reference pixels supported by the decoder is the minimum number of vertical pixels output by the decoder at one time, and the number of vertical reference pixels is recorded as baseY.

baseX and baseY are related to decoder capability, and when the decoder capability is stronger, the smaller the number of horizontal reference pixels baseX, the smaller the number of horizontal pixels that the decoder outputs at a minimum at a time, and the smaller the number of vertical reference pixels baseY, the smaller the number of vertical pixels that the decoder outputs at a minimum at a time. When the decoder capability is weaker, the larger the number of horizontal reference pixels baseX, the larger the number of horizontal pixels that the decoder outputs at a minimum at a time, and the larger the number of vertical reference pixels baseY, the larger the number of vertical pixels that the decoder outputs at a minimum at a time.

The baseX and the baseY can be configured arbitrarily according to the decoder capability, and the values of the baseX and the baseY are not limited, for example, the baseX can be an integer multiple of 2, such as 2, 4, 6, 8, 16, 24, 32, etc., and the baseY can be an integer multiple of 2, such as 2, 4, 6, 8, 16, 24, 32, etc. When baseX is 2, it means that the decoder outputs 2 horizontal pixels at a time, when baseX is 4, it means that the decoder outputs 4 horizontal pixels at a time, and so on. When baseY is 2, it means that the decoder outputs a minimum of 2 vertical pixels at a time, when baseY is 4, it means that the decoder outputs a minimum of 4 vertical pixels at a time, and so on.

In summary, for the decoder, a minimum of baseX baseY pixels are output at a time, that is, a rectangular block is output, the width of the rectangular block is baseX, which indicates that the rectangular block has baseX pixels in the horizontal direction, and the height of the rectangular block is baseY, which indicates that the rectangular block has baseY pixels in the vertical direction. Assuming baseX is 2 and basey is 4, the decoder outputs 2*4 pixels at a minimum, 2 pixels horizontally and 4 pixels vertically at a time.

Illustratively, the horizontal reference pixel number baseX may be used as a horizontal alignment criterion of the decoder, that is, the width of each target window needs to be an integer multiple of the horizontal reference pixel number baseX. The number of vertical reference pixels baseY can be used as a vertical alignment criterion of the decoder, that is, the height of each target window needs to be an integer multiple of the number of vertical reference pixels baseY.

In summary, in this embodiment, the second layout information of the target window may be determined based on the first layout information, the number of horizontal reference pixels and the number of vertical reference pixels supported by the decoder.

For example, if the display screen adopts the equipartition layout mode, the second layout information may include the number of windows of the target window (e.g., M × N), where, for example, the number of windows of the target window includes the number of horizontal windows M and the number of vertical windows N, the number of horizontal windows M of the target window is the same as the number of horizontal windows M of the original window, the number of vertical windows N of the target window is the same as the number of vertical windows N of the original window, M is a positive integer greater than 1, and N is a positive integer greater than 1. Obviously, the number M of horizontal windows indicates that M target windows exist in the horizontal direction of the display screen, and the number N of vertical windows indicates that N target windows exist in the vertical direction of the display screen.

The second layout information may further include a width and a height of each target window, the width of the target window indicating how many pixels exist in the horizontal direction of the target window, i.e., the number of horizontal pixels, and the height of the target window indicating how many pixels exist in the vertical direction of the target window, i.e., the number of vertical pixels. For example, when there are M × N target windows in total, the second layout information may further include the width and height of the first target window, the width and height of the second target window, …, and the width and height of the M × N target window.

In the second layout information, the width of each target window is an integral multiple of the number of horizontal reference pixels baseX, and the height of each target window is an integral multiple of the number of vertical reference pixels baseY.

In one possible embodiment, determining the second layout information of the target window based on the first layout information, the number of horizontal reference pixels and the number of vertical reference pixels supported by the decoder may include:

step 1021, determining the target widths of M transverse candidate windows based on the number of transverse reference pixels, where the target widths of different transverse candidate windows are the same or different, and the target width of each transverse candidate window is a positive integer multiple of the number of transverse reference pixels.

For example, since the number of horizontal windows of the target window is M, the M horizontal target windows may be regarded as M horizontal candidate windows, the target width of each horizontal candidate window may be determined based on the number of horizontal reference pixels baseX, the target widths of different horizontal candidate windows may be the same or different, and the target width of each horizontal candidate window is a positive integer multiple of the number of horizontal reference pixels baseX.

For example, the target widths of the M horizontal candidate windows may be determined by:

step 10211, determining the initial widths, the number to be adjusted X1 and the target remainder Y1 of the M horizontal candidate windows based on the number M, the number baseX of the horizontal reference pixels and the total number of horizontal pixels of the display screen.

For example, in step 10211, a single channel width and a first remainder value may be determined based on the number M and the total number of horizontal pixels of the display screen, for example, a quotient of the total number of horizontal pixels and the number M is taken as a single channel width, and a remainder of the total number of horizontal pixels and the number M is taken as a first remainder value.

Then, the initial widths and the second remainder value of the M horizontal candidate windows are determined based on the single channel width and the number of horizontal reference pixels baseX, for example, a remainder of the single channel width and the number of horizontal reference pixels baseX is calculated, a difference value between the single channel width and the remainder is used as the initial width of the horizontal candidate windows, the initial width of each horizontal candidate window is the same, and a product of the remainder and the number M is used as the second remainder value.

Then, the to-be-adjusted number X1 and the target remainder Y1 are determined based on the first remainder value and the second remainder value, for example, a first total remainder is determined based on the first remainder value and the second remainder value, i.e., a sum of the first remainder value and the second remainder value is taken as the first total remainder. And determining a number to be adjusted X1 and a target remainder Y1 based on the first total remainder and the number of transverse reference pixels baseX, wherein the target remainder Y1 is smaller than the number of transverse reference pixels, and the number to be adjusted X1 is smaller than M. For example, the quotient of the first total remainder and the number of horizontal reference pixels baseX is taken as the number X1 to be adjusted, and the remainder of the first total remainder and the number of horizontal reference pixels baseX is taken as the target remainder Y1.

Step 10212, select X1 horizontal candidate windows from all horizontal candidate windows before the last horizontal candidate window, and determine the target width of the horizontal candidate window based on the initial width of the selected horizontal candidate window and the number baseX of horizontal reference pixels. For example, to determine the target width of the horizontal candidate window, the target width of the horizontal candidate window may be determined based on the sum of the initial width of the selected horizontal candidate window and the number of horizontal reference pixels baseX. For example, the sum of the initial width of the selected horizontal candidate window and the number baseX of horizontal reference pixels is used as the target width of the horizontal candidate window.

For example, if M is 4 and X1 is 2, a first lateral candidate window and a second lateral candidate window may be selected from the 4 lateral candidate windows, or a first lateral candidate window and a third lateral candidate window may be selected, or a second lateral candidate window and a third lateral candidate window may be selected, which is not limited to this, as long as the last lateral candidate window is not selected. Taking the selection of the second horizontal candidate window and the third horizontal candidate window as an example, the target width of the second horizontal candidate window is the sum of the initial width of the second horizontal candidate window and the number of horizontal reference pixels baseX, and the target width of the third horizontal candidate window is the sum of the initial width of the third horizontal candidate window and the number of horizontal reference pixels baseX.

At step 10213, a target width of the last horizontal candidate window is determined based on the initial width of the horizontal candidate window and the target remainder Y1. For example, if the target remainder Y1 is in the interval [0, k1-1], determining the target width of the horizontal candidate window based on the initial width of the horizontal candidate window, such as the initial width of the horizontal candidate window being the target width of the horizontal candidate window; if the target remainder Y1 is in the interval [ K1, K2-1], determining the target width of the horizontal candidate window based on the initial width of the horizontal candidate window and the number of horizontal reference pixels baseX, e.g., the sum of the initial width of the horizontal candidate window and the number of horizontal reference pixels baseX, as the target width of the horizontal candidate window. Illustratively, K2 may be the number of horizontal reference pixels baseX, and K1 is greater than 0 and less than K2, for example, K1 may be a quotient of the number of horizontal reference pixels baseX divided by 2.

Assuming that M is 4, for a fourth horizontal candidate window (last horizontal candidate window), if Y1 is in the interval [0, basex/2-1], the target width of the fourth horizontal candidate window is the initial width of the fourth horizontal candidate window; if Y1 is in the interval [ baseX/2, baseX-1], the target width of the fourth lateral candidate window is the sum of the initial width of the fourth lateral candidate window and the number of lateral reference pixels baseX.

Step 10214, for each lateral candidate window other than the selected X1 lateral candidate windows and the last lateral candidate window, determining a target width of the lateral candidate window based on the initial width of the lateral candidate window. For example, the initial width of the horizontal candidate window is taken as the target width of the horizontal candidate window.

For example, assuming that M is 4, for the selected second and third horizontal candidate windows and the horizontal candidate window outside the last horizontal candidate window (i.e. the first horizontal candidate window), the target width of the first horizontal candidate window is the initial width of the first horizontal candidate window.

In summary, for all 4 horizontal candidate windows, the target width of each horizontal candidate window can be determined, as shown in steps 10212, 10213 and 10214. To this end, the target widths of the M lateral candidate windows may be determined based on the number of lateral reference pixels baseX.

Step 1022, determining target heights of the N longitudinal candidate windows based on the number of the longitudinal reference pixels, where the target heights of different longitudinal candidate windows are the same or different, and the target height of each longitudinal candidate window is a positive integer multiple of the number of the longitudinal reference pixels.

For example, since the number of the vertical windows of the target window is N, the vertical N target windows may be regarded as N vertical candidate windows, the target height of each vertical candidate window may be determined based on the number baseY of the vertical reference pixels, the target heights of different vertical candidate windows are the same or different, and the target height of each vertical candidate window is a positive integer multiple of the number baseY of the vertical reference pixels.

For example, the target heights of the N vertical candidate windows may be determined by the following steps:

step 10221, based on the number N, the number baseY of the longitudinal reference pixels, and the total number of longitudinal pixels of the display screen, determine the initial heights of the N longitudinal candidate windows, the number X2 to be adjusted, and the target remainder Y2.

For example, in step 10221, a single channel height and a third remainder value may be determined based on the number N and the total number of vertical pixels of the display screen, for example, a quotient of the total number of vertical pixels and the number N is taken as the single channel height, and a remainder of the total number of vertical pixels and the number N is taken as the third remainder value.

Then, the initial heights and the fourth remainder value of the N vertical candidate windows are determined based on the single channel height and the number of vertical reference pixels baseY, for example, a remainder of the single channel height and the number of vertical reference pixels baseY is calculated, a difference value between the single channel height and the remainder is used as the initial height of the vertical candidate windows, the initial height of each vertical candidate window is the same, and a product of the remainder and the number N is used as the fourth remainder value.

Then, the number to be adjusted X2 and the target remainder Y2 are determined based on the third remainder value and the fourth remainder value, for example, a second total remainder is determined based on the third remainder value and the fourth remainder value, i.e., a sum of the third remainder value and the fourth remainder value is taken as the second total remainder. And determining a number to be adjusted X2 and a target remainder Y2 based on the second total remainder and the longitudinal reference pixel number baseY, wherein the target remainder Y2 is less than the longitudinal reference pixel number, and the number to be adjusted X2 is less than N. For example, the quotient of the second total remainder and the number baseY of vertical reference pixels is taken as the number X2 to be adjusted, and the remainder of the second total remainder and the number baseY of vertical reference pixels is taken as the target remainder Y2.

Step 10222, select X2 vertical candidate windows from all vertical candidate windows before the last vertical candidate window, and determine the target height of the vertical candidate window based on the initial height of the selected vertical candidate window and the number baseY of vertical reference pixels. For example, to determine the target height of the vertical candidate window, the target height of the vertical candidate window may be determined based on the sum of the initial height of the selected vertical candidate window and the vertical reference pixel number baseY. For example, the sum of the initial height of the selected vertical candidate window and the base pixel number baseY is used as the target height of the vertical candidate window.

For example, if N is 4 and X2 is 2, a second vertical candidate window and a third vertical candidate window may be selected from the 4 vertical candidate windows, where a target height of the second vertical candidate window is a sum of an initial height of the second vertical candidate window and the reference pixel number baseY, and a target height of the third vertical candidate window is a sum of an initial height of the third vertical candidate window and the reference pixel number baseY.

At step 10223, a target height of the vertical candidate window is determined based on the initial height of the last vertical candidate window and the target remainder Y2. For example, if the target remainder Y2 is in the interval [0, k3-1], determining the target height of the vertical candidate window based on the initial height of the vertical candidate window, such as the initial height of the vertical candidate window being the target height of the vertical candidate window; if the target remainder Y2 is in the interval [ K3, K4-1], determining the target height of the vertical candidate window based on the initial height of the vertical candidate window and the number of vertical reference pixels baseY, for example, the sum of the initial height of the vertical candidate window and the number of vertical reference pixels baseY is used as the target height of the vertical candidate window. Illustratively, K4 may be the longitudinal reference pixel number baseY, and K3 is greater than 0 and less than K4, for example, K3 may be the quotient of the longitudinal reference pixel number baseY divided by 2.

Assuming that N is 4, for the fourth vertical candidate window (the last vertical candidate window), if Y2 is in the interval [0, base Y/2-1], the target height of the fourth vertical candidate window is the initial height of the fourth vertical candidate window; if Y2 is in the interval [ baseY/2, baseY-1], the target height of the fourth longitudinal candidate window is the sum of the initial height of the fourth longitudinal candidate window and the longitudinal reference pixel number baseY.

At step 10224, for each longitudinal candidate window other than the selected X2 longitudinal candidate windows and the last longitudinal candidate window, a target height of the longitudinal candidate window is determined based on the initial height of the longitudinal candidate window. For example, the initial height of the vertical candidate window is taken as the target height of the vertical candidate window.

For example, assuming that N is 4, for the selected second vertical candidate window and the third vertical candidate window, and the vertical candidate window outside the last vertical candidate window (i.e. the first vertical candidate window), the target height of the first vertical candidate window is the initial height of the first vertical candidate window.

In summary, for all 4 vertical candidate windows, the target height of each vertical candidate window can be determined, as shown in step 10222, step 10223 and step 10224. To this end, the target heights of the N longitudinal candidate windows may be determined based on the longitudinal reference pixel number baseY.

In step 1023, the number of windows of the target window is determined based on the number M and the number N. For example, the number M of horizontal windows of the target window is the same as the number M of horizontal windows of the original window, the number N of vertical windows of the target window is the same as the number N of vertical windows of the original window, and the number of windows of the target window may be M × N.

Step 1024, determining the width and height of each target window based on the target widths of the M horizontal candidate windows and the target heights of the N vertical candidate windows. The width of each target window (representing how many pixels exist in the lateral direction of the target window, i.e., the number of lateral pixels) is a positive integer multiple of the number of lateral reference pixels baseX, and the height of each target window (representing how many pixels exist in the longitudinal direction of the target window, i.e., the number of longitudinal pixels) is a positive integer multiple of the number of longitudinal reference pixels baseY.

Assuming that M is 4,N is 2, the number of horizontal reference pixels baseX is 2, and the number of vertical reference pixels baseY is 4,M horizontal candidate windows have target widths of 8, 10, 8,2 vertical candidate windows have target heights of 12, 16: the number of target windows is 4*2, the width and height of the first target window (corresponding to the first transverse candidate window and the first longitudinal candidate window) is 8 × 12, the width and height of the second target window (corresponding to the second transverse candidate window and the first longitudinal candidate window) is 10 × 12, the width and height of the third target window (corresponding to the third transverse candidate window and the first longitudinal candidate window) is 10 × 12, the width and height of the fourth target window (corresponding to the fourth transverse candidate window and the first longitudinal candidate window) is 8 × 12, the width and height of the fifth target window (corresponding to the first transverse candidate window and the second longitudinal candidate window) is 8 × 16, the width and height of the sixth target window (corresponding to the second transverse candidate window and the second longitudinal candidate window) is 10 × 16, the width and height of the seventh target window (corresponding to the third transverse candidate window and the second longitudinal candidate window) is 10 × 16, and the width and height of the fourth target window (corresponding to the fourth transverse candidate window and the fourth longitudinal candidate window) is 8 × 16.

For example, if the display screen adopts the free layout mode, the second layout information may include the number of windows of the target window, where the number of windows of the target window is the same as the number of windows of the original window. The second layout information may further include vertex coordinates (e.g., upper left corner coordinates, upper right corner coordinates, lower left corner coordinates, lower right corner coordinates, center point coordinates, etc.), a width and a height of each target window, where the width of a target window indicates how many pixels exist in the horizontal direction of the target window, i.e., the number of horizontal pixels, and the height of a target window indicates how many pixels exist in the vertical direction of the target window, i.e., the number of vertical pixels. For example, the second layout information may further include vertex coordinates (which may be the same as the vertex coordinates of the first original window), width, and height of the first target window, vertex coordinates, width, and height of the second target window, and so on.

step S11, determining, for each original window, a remainder of the initial width of the original window and the number of horizontal reference pixels baseX, and determining a target width of the original window based on the initial width of the original window and the remainder, where the target width is a positive integer multiple of the number of horizontal reference pixels baseX.

For example, assuming that the coordinates of the original window are [ x, y, width, height ], x and y are coordinates of the upper left corner of the original window, width is the initial width of the original window, and height is the initial height of the original window, the remainder of the initial width of the original window and the number of horizontal reference pixels baseX, that is, the value of width% baseX, is determined. Then, the difference between the initial width of the original window and the remainder (width-width% baseX) is determined as the target width of the original window, or the difference between the initial width of the original window and the remainder, plus the sum of the number of transverse reference pixels baseX (width-width% baseX + baseX) is determined as the target width of the original window. Of course, the above are only two examples, and there is no limitation to this, as long as the target width can be obtained based on the initial width of the original window and the remainder, and the target width is a positive integer multiple of baseX.

Step S12, aiming at each original window, determining the remainder of the initial height of the original window and the longitudinal reference pixel number baseY, and determining the target height of the original window based on the initial height of the original window and the remainder, wherein the target height is a positive integer multiple of the longitudinal reference pixel number baseY.

For example, assuming that the initial height is heigth, a remainder of the initial height heigth of the original window and the number baseY of the longitudinal reference pixels, i.e., a value of heigth% baseY, is determined. Then, the difference between the initial height of the original window and the remainder (height-height% baseY) may be determined as the target height of the original window, or the difference between the initial height of the original window and the remainder, plus the sum of the number of vertical reference pixels baseY (height-height% baseY + baseY) may be determined as the target height of the original window. Of course, the above are only two examples, and no limitation is made to this, as long as the target height can be obtained based on the initial height of the original window and the remainder, and the target height is a positive integer multiple of the number baseY of the longitudinal reference pixels.

Step S13, determining the number of the target windows based on the number of the original windows (namely, the number of the target windows is the same as that of the original windows), and determining the vertex coordinates of the target windows, the width and the height of the target windows based on the vertex coordinates, the target width and the target height of the original windows.

For example, the vertex coordinates of the original window may be used as the vertex coordinates of the target window, the target width corresponding to the initial width of the original window may be used as the width of the target window, and the target height corresponding to the initial height of the original window may be used as the height of the target window. To this end, the width and height of each target window can be obtained, the width of each target window (representing how many pixels exist in the transverse direction of the target window) is a positive integer multiple of the transverse reference pixel number baseX, and the height of each target window (representing how many pixels exist in the longitudinal direction of the target window) is a positive integer multiple of the longitudinal reference pixel number baseY.

To this end, step 102 is completed, and no matter in the even layout mode or the free layout mode, the second layout information of the target windows can be obtained, and the second layout information may include the number of windows of the target windows, and the width and height of each target window.

And 103, dividing a plurality of target windows on the display screen based on the second layout information.

Illustratively, the widths of the different target windows are the same or different, and the heights of the different target windows are the same or different; and the width of each target window is a positive integer multiple of the number baseX of the horizontal reference pixels, and the height of each target window is a positive integer multiple of the number baseY of the vertical reference pixels.

For example, in the equipartition layout mode, 4*2 target windows may be divided on the display screen based on the second layout information, the width and height of the first target window is 8 × 12, the width and height of the second target window is 10 × 12, the width and height of the third target window is 10 × 12, the width and height of the fourth target window is 8 × 12, the width and height of the fifth target window is 8 × 16, the width and height of the sixth target window is 10 × 16, the width and height of the fourth target window is 10 × 16, and the width and height of the eighth target window is 8 × 16. Up to this point, 8 target windows are divided on the display screen, the width of each target window is a positive integer multiple of baseX, and the height of each target window is a positive integer multiple of baseY.

And 104, displaying the video data through a plurality of target windows divided on the display screen.

In a possible implementation manner, when the display screen is in the equipartition layout mode, the window alignment standard in the equipartition layout mode is adopted to divide a plurality of target windows on the display screen. For example, in the manner from step 1021 to step 1024, the second layout information of the target window is determined, and a plurality of target windows are divided on the display screen according to the second layout information. On the basis, if the display screen is switched from the equipartition layout mode to the free layout mode, a plurality of target windows are divided on the display screen based on the window alignment standard in the free layout mode. For example, in the manner of step S11 to step S13, the second layout information of the target window is determined, and the plurality of target windows are divided on the display screen according to the second layout information.

For example, in the uniform layout mode, if the windowing operation is performed (see the following embodiments for related meanings), it means that the uniform layout mode is switched to the free layout mode, that is, the windowing operation belongs to the free layout mode. In the equipartition layout mode, if a roaming operation is performed (see the following embodiments for related meanings), it means that the equipartition layout mode is switched to the free layout mode, that is, the roaming operation belongs to the free layout mode.

In a possible implementation manner, when the display screen is in the free layout mode, the window alignment standard in the free layout mode is adopted to divide a plurality of target windows on the display screen. For example, in the manner of step S11 to step S13, the second layout information of the target window is determined, and the plurality of target windows are divided on the display screen according to the second layout information. On the basis, if the display screen is switched from the free layout mode to the uniform layout mode, a plurality of target windows are divided on the display screen based on the window alignment standard in the uniform layout mode. For example, in the manner from step 1021 to step 1024, the second layout information of the target window is determined, and the plurality of target windows are divided on the display screen according to the second layout information.

For example, the execution sequence is only an example given for convenience of description, and in practical applications, the execution sequence between the steps may also be changed, and the execution sequence is not limited. Moreover, in other embodiments, the steps of the respective methods do not have to be performed in the order shown and described herein, and the methods may include more or less steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps in other embodiments for description; multiple steps described in this specification may be combined into a single step in other embodiments.

According to the technical scheme, the display screen can display a plurality of windows, the layout information of the windows can be automatically acquired, and a plurality of target windows are divided on the display screen based on the layout information, so that the display screen is divided into a plurality of areas, and a display screen can display a plurality of program contents. The bottom layer alignment standard can be met when a plurality of windows are divided, large gaps or blue edges between different windows are avoided, or the gaps are transferred to the rightmost edge and the bottommost edge of the display screen, the positions of the windows are accurately controlled, the windows are guaranteed to be closely adsorbed, the impact of the gaps in vision is relieved, the display effect is improved, and the watching experience of users is improved.

The data display method according to the embodiment of the present application will be described below with reference to specific embodiments. Before describing the data display method according to the embodiment of the present application, the concept related to the embodiment of the present application will be described.

A display screen: a screen capable of displaying video data, where the display screen may be an LED (Light Emitting Diode) display screen, a full-color screen, a video wall, or the like, and the type of the display screen is not limited, as long as the display screen supports a plurality of windows, video data may be displayed through each window.

The full-color screen is a display screen by controlling RGB (red green blue ) semiconductor light emitting diodes, and has the characteristics of rich colors, high saturation, high resolution, high display frequency and the like. The television wall is formed by splicing the LED display units and has the characteristics of being seamless, high in color reduction degree, strong in modeling plasticity and the like.

Windowing: in the display area of the display screen, a window of a desired size and position is created.

Roaming: and in the display area of the display screen, carrying out dragging movement and size change operation on the window.

A decoder: the PC end can control the decoder to perform windowing, roaming and other operations after the decoder is introduced, and the decoder can divide a display screen into a plurality of windows and display a plurality of contents in the plurality of windows of the display screen.

And (3) coordinate system: the upper left corner of the display screen may be taken as the (0,0) coordinate position, with increasing x-axis coordinates from left to right in the horizontal direction and increasing y-axis coordinates from top to bottom in the vertical direction. For each window within the display screen, the window may be decomposed into an x-axis direction and a y-axis direction, as shown in FIG. 2.

In summary, it can be seen that, for each window, the width of the window and the height of the window may be uniquely determined by the coordinate of the upper left corner of the window, and certainly, the window may also be uniquely determined by other parameters, for example, the width of the window and the height of the window may be uniquely determined by the coordinate of the upper right corner of the window, or the width of the window and the height of the window may be uniquely determined by the coordinate of the lower left corner of the window, or the coordinates of 4 corner points of the window, which is not limited in this regard.

Free layout mode and equipartition layout mode: in the free layout mode, a plurality of windows are arbitrarily divided on the display screen, and as shown in fig. 3, the window is a schematic diagram of arbitrarily dividing 5 windows (such as window 1, window 2, window 3, window 4, and window 5) on the display screen. In the uniform distribution layout mode, a plurality of windows are equally divided on the display screen, which is shown in fig. 3, and is a schematic diagram of equally dividing 4*3 windows (e.g. window 1-window 12) on the display screen. Of 4*3 windows, 4 denotes the number of horizontal windows, i.e., there are 4 windows in the horizontal direction, i.e., M in the above embodiment. 3 denotes the number of vertical windows, i.e. there are 3 windows vertically, i.e. N in the above embodiment. In the following embodiments, a data display method in the uniform layout mode is taken as an example for explanation, and details of the data display method in the free layout mode are not described in the following process. When the display screen adopts the equipartition layout mode, the display screen can be averagely divided into a plurality of windows. Referring to fig. 4, a flowchart of a data display method in the equipartition layout mode, which may be applied to a decoder, may include:

step 401, obtaining first layout information of an original window, where the first layout information may include a number M of horizontal windows and a number N of vertical windows.

Step 402, determining a single channel width and a first remainder value based on the number M of the horizontal windows and the total number of horizontal pixels of the display screen, for example, a quotient of the total number of the horizontal pixels and the number M may be used as the single channel width, and a remainder of the total number of the horizontal pixels and the number M may be used as the first remainder value.

Illustratively, the total number of horizontal pixels of the display screen represents the horizontal resolution supported by the display screen, that is, the sum of resolutions corresponding to all output channels of the decoder (the resolutions of different output channels may be the same or different, and only the sum of resolutions corresponding to all output channels needs to be obtained), that is, the sum of resolutions corresponding to all output channels is the total number of horizontal pixels of the display screen, and is denoted as Res _total 。

Res can be adjusted _total The quotient of M is the width of a single channel, which is designated as Res _single Res can be adjusted _total The remainder of the sum M is taken as the first remainder value, which is denoted as K1, res _total 、M、K1、Res _single The relationship (c) can be shown in equation (1).

For example, let Res be _total 101, M is 4, res _single Is 25, and K1 is 1.

In step 403, the initial widths and the second remainder values of the M horizontal candidate windows are determined based on the single channel width and the horizontal reference pixel number baseX. For example, calculate the width Res of a single channel _single With transverse reference imageThe remainder of the prime number baseX, the single channel width Res _single The difference from the remainder is taken as the initial width of the horizontal candidate window, and the initial width of each horizontal candidate window can be recorded as Res _avg And the product of the remainder and the number M is taken as a second remainder value, which may be denoted as K2.

For example, if Res _single 25, the number of transverse reference pixels baseX is 2, the single channel width Res _single The remainder from the number of horizontal reference pixels baseX may be 1, the initial width Res of each horizontal candidate window _avg May be 24 (i.e., 25-1) and the second remainder value K2 may be 4 (i.e., 1*4).

In step 404, a first total remainder is determined based on the first remainder value K1 and the second remainder value K2, i.e., a sum of the first remainder value K1 and the second remainder value K2 is taken as the first total remainder. For example, the first total remainder is denoted as Res _remind Then Res may be determined as follows _remind ：Res _remind ＝K1+K2。

Referring to FIG. 5A, the total number of horizontal pixels Res of the display screen _total Is divided into 4 AVGs, and the value of each AVG is the initial width Res of the horizontal candidate window _avg And, the total number of lateral pixels Res _total The method can also comprise a reserved, and the value of the reserved is the first total remainder Res _remind 。

Step 405, determining a number to be adjusted X1 and a target remainder Y1 based on the first total remainder and the number of horizontal reference pixels baseX, where the target remainder Y1 is smaller than the number of horizontal reference pixels baseX, and the number to be adjusted X1 is smaller than M. For example, the quotient of the first total remainder and the horizontal reference pixel number baseX is taken as the number X1 to be adjusted, and the remainder of the first total remainder and the horizontal reference pixel number baseX is taken as the target remainder Y1.

For example, the first overall remainder Res _remind Is 5 (the sum of the first remainder value 1 and the second remainder value 4), the number of horizontal reference pixels baseX is 2, the quotient of the first total remainder and the number of horizontal reference pixels baseX is 2, the remainder of the first total remainder and the number of horizontal reference pixels baseX is 1, that is, the number to be adjusted X1 is 2, and the target remainder Y1 is 1.Res _remind The relationship among baseX, X1 and Y1 is shown in formula (2).

Res _remind = X1 baseX + Y1 formula (2)

Referring to FIG. 5B, the first overall remainder Res _remind Can be divided into 2 baseX whose value is the number of the horizontal reference pixels baseX and 1Y whose value is the target remainder Y1.

Step 406, selecting X1 horizontal candidate windows from all horizontal candidate windows before the last horizontal candidate window, and determining the target width of the horizontal candidate window based on the initial width of the selected horizontal candidate window and the horizontal reference pixel number baseX. For example, the initial width Res of the horizontal candidate window to be selected _avg And the sum of the number baseX of the horizontal reference pixels is used as the target width of the horizontal candidate window.

For example, X1 horizontal candidate windows may be selected sequentially from the second-to-last horizontal candidate window. For another example, X1 horizontal candidate windows may be selected from the middle positions of all the horizontal candidate windows. For another example, X1 horizontal candidate windows may be selected sequentially from the third last horizontal candidate window and onwards. For another example, X1 horizontal candidate windows may be selected sequentially backward from the first horizontal candidate window. Of course, the above are only a few examples, and the selection manner of the horizontal candidate window is not limited.

Step 407 determines the target width of the last horizontal candidate window based on the initial width of the horizontal candidate window and the target remainder Y1. For example, if the target remainder Y1 is in the interval

The initial width Res of the horizontal candidate window may be set _avg As the target width of the horizontal candidate window; if the target remainder Y1 is in the range->

The initial width Res of the horizontal candidate window may be set _avg Sum of the number of transverse reference pixels baseXIs the target width of the horizontal candidate window. For example, assume that the target width of the horizontal candidate window is Res _last Then the target width can be determined using equation (3).

Step 408, for each lateral candidate window other than the selected X1 lateral candidate windows and the last lateral candidate window, determining a target width of the lateral candidate window based on the initial width of the lateral candidate window. For example, the initial width of a horizontal candidate window is taken as the target width of the horizontal candidate window.

In summary, for steps 406-408, the target width of each horizontal candidate window can be seen in fig. 5C and 5D, where in fig. 5C, the target remainder Y1 is in the interval

For example, the number of horizontal reference pixels baseX may be complemented for the second horizontal candidate window, the third horizontal candidate window and the fourth horizontal candidate window, i.e. the target width is the sum of the initial width and baseX. The width of the first horizontal candidate window may be kept constant, i.e. the target width is the initial width. In FIG. 5D, the target remainder Y1 is in the bin @>

For example, the second horizontal candidate window and the third horizontal candidate window are complemented with the horizontal reference pixel number baseX, i.e. the target width is the sum of the initial width and baseX. The widths of the first horizontal candidate window and the fourth horizontal candidate window are kept unchanged, i.e. the target width is the initial width.

In summary, for 4 horizontal candidate windows, the target width of the horizontal candidate window may be [ Res ] in sequence _avg ，Res _avg +baseX，Res _avg +baseX，Res _avg +baseX]Or, the target width of the horizontal candidate window may be [ Res ] in turn _avg ，Res _avg +baseX，Res _avg +baseX，Res _avg ]。

And step 409, determining the single-channel height and a third remainder value based on the number N of the longitudinal windows and the total number of longitudinal pixels of the display screen. And determining the initial heights and the fourth remainder values of the N longitudinal candidate windows based on the single-channel height and the longitudinal reference pixel number baseY. A second total remainder is determined based on the third remainder value and the fourth remainder value. Based on the second total remainder and baseY, the number to be adjusted X2 and the target remainder Y2 are determined.

Step 410, selecting X2 longitudinal candidate windows from all longitudinal candidate windows before the last longitudinal candidate window, and determining the target height of the longitudinal candidate window based on the initial height of the selected longitudinal candidate window and the longitudinal reference pixel number baseY. And, a target height for the vertical candidate window may be determined based on the initial height of the last vertical candidate window and the target remainder Y1. And for each longitudinal candidate window except the selected X2 longitudinal candidate windows and the last longitudinal candidate window, determining the target height of the longitudinal candidate window based on the initial height of the longitudinal candidate window.

For example, steps 409 to 410 may refer to steps 402 to 408, except that the transverse process is replaced by the longitudinal process, and the width is replaced by the height, which is not repeated herein.

Step 411, determining second layout information of the target windows based on the target widths of the number M, the number N, M transverse candidate windows and the target heights of the N longitudinal candidate windows, where the second layout information may include the number of the target windows, the width and the height of each target window.

Illustratively, the width of each target window is a positive integer multiple of the number of horizontal reference pixels baseX, and the height of each target window is a positive integer multiple of the number of vertical reference pixels baseY.

In step 412, a plurality of target windows are divided on the display screen based on the second layout information. Illustratively, the widths of the different target windows are the same or different, and the heights of the different target windows are the same or different; and the width of each target window is a positive integer multiple of the horizontal reference pixel number baseX, and the height of each target window is a positive integer multiple of the vertical reference pixel number baseY.

In step 413, the video data is displayed through a plurality of target windows divided on the display screen.

According to the technical scheme, in the embodiment of the application, a plurality of windows can be displayed on the display screen in an equipartition layout mode, the layout information of the windows is automatically acquired by the data display equipment, and a plurality of target windows are divided on the display screen based on the layout information, so that the display screen is divided into a plurality of areas, and a plurality of program contents are displayed on one display screen. The bottom layer alignment standard can be met when a plurality of windows are divided, large gaps or blue edges between different windows are avoided, or the gaps are transferred to the rightmost edge and the bottommost edge of the display screen, the positions of the windows are accurately controlled, the windows are guaranteed to be closely adsorbed, the impact of the gaps in vision is relieved, the display effect is improved, and the watching experience of users is improved.
