Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a schematic view illustrating a usage scenario of a windowing control method in a display control system according to an embodiment of the present invention. In the field of display technology, a display control system is used for controlling the display effect of input signals on a display screen, for example, displaying each signal in a split screen mode, displaying one signal in a whole screen mode, outputting and displaying after splicing the signals, outputting and displaying after locally cutting the input signals, and the like. Since display control systems are well known to those skilled in the art, they will not be described herein. The display control system may be, for example, a multi-screen stitching processor. The multi-screen splicing processor B is respectively connected with the main computer A, the at least one auxiliary computer 101-n and the screen C, and the signal source content in each auxiliary computer is displayed on the splicing screen C in real time. The multi-screen splicing processor B is used for receiving the signal source contents of the auxiliary computers 101-n and sending the signal source contents to the splicing screen C for displaying. The host computer a may initiate a windowing request to the multi-screen stitching processor B.
First embodiment
Referring to fig. 2, fig. 2 is a flowchart illustrating a windowing control method executed by a multi-screen splicing processor B according to a first embodiment of the present invention. The method comprises the following steps:
s11: a windowing request is received.
The multi-screen mosaic processor B receives a windowing request on the mosaic screen, which may be for causing pictures, videos, text, charts, executables, web links, desktops, etc. of some secondary computer n to be displayed on the screen C.
S12: the number of old windows and the id of the old windows are determined.
The source of the window information existing in the mosaic screen C may be the content of each signal source (e.g., the secondary computer 102), and the content of the signal source may be information associated with the signal source, such as pictures, videos, characters, diagrams, executable files, web links, desktops, etc., which is preset by automatic opening; or some auxiliary computer desktop; or monitoring a picture, etc.
In this case, the number of windows opened and the window characteristic information in the mosaic screen C are determined. The window characteristic information can take two coordinate values x, y in vertex coordinates (x, y) at the upper left corner of the window as parametersConnected in order as the id of the window. For example, Window WINDOWATop left corner vertex coordinate (x)A,yA) To (100 ), WINDOW is directly put into WINDOWAId of 100100.
S13: the id of the new window is calculated.
S14: comparing the new window id with all the old window ids;
if the new window id is the same as the id of a certain old window, closing the old window and opening the new window, wherein the total number of the windows is unchanged;
if the new window id is different from any old window id, then the total number of windows is + 1.
S15: comparing the total number of windows with a window number threshold; and if the window is smaller than or equal to the threshold value, opening a new window.
And the multi-screen splicing processor B continuously updates the number of the existing windows in the spliced screen C and determines that the number of the existing windows does not exceed the processing threshold of the multi-screen splicing processor B.
Fig. 3 is a schematic diagram illustrating a first decomposition flow of step S13 in the windowing control method in the display control system according to the first embodiment of the present invention.
In this step, the method for calculating the new window id may include:
s131: setting an allowable maximum deviation range Δ o in the display control system;
for example, the system is set such that the allowable maximum offset range is Δ o 50.
The new window id may cover different parameters, which in one embodiment may be the coordinates of the top left vertex of the new window considered:
s132-1: WINDOW for setting new WINDOWBHas an X-axis coordinate ofBThe Y-axis coordinate is YB(ii) a For example, WINDOW, which requires opening a WINDOW on the main display screenBPosition (x)B，yB) Is (100 ).
S133-1: calculate the closest xBThe value x' of an integer multiple of Δ o; calculate the closest yBThe value y' of an integer multiple of Δ o;
for example, the calculation formula is int (((x/Δ o) + 0.5)). DELTA.o, int (((y/Δ o) + 0.5)). Δ o. The above case xB120, Δ o is 50, and the integer multiple of Δ o has two numbers adjacent to 120, i.e., 100 and 150. Here, the absolute value of the difference between 100 and 120 is smaller, so x 'is 100 and y' is 100.
S134-1: directly connecting x 'y' in sequence to serve as id of a new window;
the two values can be directly concatenated in x 'y' order as the id of the window, e.g., x '100, y' 100, and the new window id is directly determined as 100100.
In the above case, WINDOW WINDOWs is opened on the screenBPosition is (x)B，yB) (120 ), size (a)B，bB) Is (480 ). If x 'is 100, y' is 100, id is 100100, and id of window B is (100100) according to the formula, the id of window B coincides with the id of window a, and thus window B replaces window a.
Next, a window C is opened on the large screen at the position of (x)C，yC) (140 ) having the size of (a)C，bC) (470 ), according to the formula x 1-150, y 1-150, id is calculated to be 150150, and id of window C is (150150), then window C does not replace window B.
In another embodiment, the size of the window is considered to be a variable in the calculation of the id of the new window, so that the old window opened by the user is estimated by accurately considering the position and size of the new window. Fig. 4 is a second decomposition flow chart of step S13 in the windowing control method in the display control system according to the first embodiment of the invention. The examples are as follows:
the another method for calculating the new window id specifically comprises the following steps:
s131: setting an allowable maximum deviation range Δ o in the display control system;
for example, the maximum allowable offset range in the system is set to Δ o equal to 50.
S132-2: WINDOW for setting new WINDOWBHas an X-axis coordinate ofBThe Y-axis coordinate is YBSetting the length and width (w) of the windowB，hB)；
For example, WINDOW, which requires opening a WINDOW on the main display screenBPosition (x)B，yB) Is (100 ), size (w)B，hB) Is (500 ).
S133-2: respectively calculate the closest xBIs closest to yBY ' nearest to the integer multiple of Δ o of w, w ' nearest to the integer multiple of Δ o of h, h ';
s134-2: the above four values are connected in the order of, for example, (x ', y', w ', h') as the id of the window.
For example, the maximum allowable shift range is set to be Δ o equal to 50, a window is opened on a large screen, the position is (100 ), the size is (500 ), the window is calculated to be (100100500500) according to the formula int (((x/Δ o) + 0.5)). Δ o, int (((y/Δ o) + 0.5)). Δ ox1 equal to 100, y1 equal to 100, h1 equal to 500, and w1 equal to 500;
opening WINDOWB on the screen, the position is (120 ), the size is (480 ), calculating according to the formula to obtain x 1-100, y 1-100, h 1-500, w 1-500, calculating to obtain id 100100500500, and WINDOW WINDOWBBId of (100100500500), so the WINDOW WINDOWBWindow can be replacedA。
Then, open WINDOW WINDOW on large screenCThe position is (140 ), the size is (470 ), id is 150150450450 calculated according to the formula x 1-150, y 1-150, h 1-450, w 1-450, and WINDOW WINDOWs is WINDOWCId of (150150450450), so WINDOW WINDOWCWindow can not be replacedB。
In addition, as can be understood by those skilled in the art from the above description, the specific way to obtain the new window id may also be to calculate a summary of the connected values as the window id by using a summarization algorithm after connection.
Furthermore, in another new window id calculation process, when a window is opened on a large screen, in addition to determining the position of the window, if the position is the same, it is determined whether the size of the new window is larger than that of the original window, and if the size of the new window is larger than that of the original window or smaller than that of the original window but the difference between the size of the new window and that of the original window is within a specified range, the new window id is the same as the old window id, that is, the window that has been opened is replaced, and the new window is not reopened.
Fig. 5 is a third exploded flowchart of step S13 in the method of controlling windowing in a display control system according to the first embodiment of the present invention. The another method for calculating the new window id specifically comprises the following steps:
s131: a maximum window difference Δ o allowed to be set in the display control system;
for example, the maximum allowable window difference Δ o in the system is set to 20.
S132-3: WINDOW for setting new WINDOWBHas an X-axis coordinate ofBThe Y-axis coordinate is YBWindow size (w)B，hB)；
S133-3: calculate the closest xBThe value x' of an integer multiple of Δ o; calculate the closest yBThe value y' of an integer multiple of Δ o;
for example, the formula is calculated as int (((x/Δ o) +0.5)) Δ o, int (((y/Δ o) +0.5)) Δ o. The above case xB120, Δ o is 50, and the integer multiple of Δ o has two numbers adjacent to 120, i.e., 100 and 150. Here, the absolute value of the difference between 100 and 120 is smaller, so x 'is 100 and y' is 100.
S133-4: if x' y ═ xByBThen judge the new WINDOW WINDOWBWhether the difference from the size of the old window is less than Δ o;
s134-3: if the current window id is less than the current window id, the new window id is equal to the old window id;
thus, when a new window is opened on the main screen, whether the upper left corner coordinate of the new window is consistent with the coordinate of the existing window or is near the existing window is judged according to the position of the existing window, if so, the opened window at the original position is not needed according to the analysis of the intention of the user, a signal source (the signal source can be, for example, a monitoring picture or a monitoring desktop) is displayed at the original window position, or the original window is replaced by the new window without re-opening the new window. This prevents an excessive number of windows.

The terms are the same as the multi-signal source scheduling method, and specific implementation details may refer to the description in the method embodiment.
