Referring to fig. 1, fig. 1 is a block diagram of a display device 100 according to an embodiment of the present disclosure. The display device 100 may be a video wall splicing system, or any other device that can be used for display. As shown in fig. 1, the display device 100 includes: memory 110, memory controller 120, and processor 130.

The memory 110 stores therein a scene switching device 200, and the scene switching device 200 includes at least one software functional module that can be stored in the memory 110 in the form of software or firmware (firmware). The processor 130 executes various functional applications and data processing by running software programs and modules stored in the memory 110, such as the scene switching apparatus 200 in the embodiment of the present application, so as to implement the scene switching method in the embodiment of the present application.
The Memory 110 may be, but is not limited to, a Random Access Memory (RAM), a Read Only Memory (ROM), a Programmable Read-Only Memory (PROM), an Erasable Read-Only Memory (EPROM), an electrically Erasable Read-Only Memory (EEPROM), and the like.

Access to the memory 110 by the processor 130 and possibly other components may be under the control of the memory controller 120.
The processor 130 may be an integrated circuit chip having signal processing capabilities. The Processor 130 may be a general-purpose Processor including a Central Processing Unit (CPU), a Network Processor (NP), and the like. But may also be a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field Programmable Gate Array (FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components. The various methods, steps, and logic blocks disclosed in the embodiments of the present application may be implemented or performed. A general purpose processor may be a microprocessor or the processor may be any conventional processor or the like.
It will be appreciated that the configuration shown in fig. 1 is merely illustrative and that the display device 100 may also include more or fewer components than shown in fig. 1 or have a different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented in hardware, software, or a combination thereof.
Referring to fig. 2, fig. 2 is a flowchart illustrating a scene switching method according to an embodiment of the present disclosure. The method is applied to the display device 100. The following describes a specific procedure of the scene switching method in detail.
Step S110, receiving a scene switching instruction for switching from a current first scene to a second scene, and obtaining second scene information.
In this embodiment, a user may save a plurality of monitoring layouts as a monitoring scene, and when there is a need, may switch a current scene to another scene, so that the display device 100 displays the needed scene. Alternatively, the scene switching instruction may be automatically generated by the display device 100, for example, the scene switching instruction is periodically generated on the basis that a plurality of scenes have been saved; or transmitted by other devices; and may also be generated based on user actions. It is understood that the scene switching instruction may be received in other manners.
Optionally, if the switched scene is not pre-saved, the display device 100 may also generate second scene information corresponding to the switched scene according to the current operation of the user, and then generate a scene switching instruction including the second scene information.
In the embodiment of the present application, the scene before the scene switching is the first scene, and the scene after the scene switching is the second scene. That is, in the adjacent previous scene and next scene, the first scene is the previous scene, and the second scene is the next scene.
Step S120, analyzing according to the first scene information and the second scene information of the first scene to obtain a priority of each first window in the first scene.
In this embodiment, in order to avoid the defect of low switching efficiency caused by the manner of directly closing all the first windows, re-windowing in the second scene, or directly and randomly roaming each first window to the second scene, the priority of each first window may be analyzed based on the first scene information and the second scene information, and then the first windows are roamed based on the priorities, so that the switching efficiency can be improved to the maximum extent, and the user experience effect is greatly improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating sub-steps included in step S120 in fig. 2. Step S120 may include substeps S121 and substep S122.
Substep S121, obtaining first scene information of the first scene.
In this embodiment, since the first scene is a currently displayed scene, the first scene information of the current first scene may be obtained based on a previous user configuration operation related to the current first scene or a previously received scene switching instruction related to the current first scene. The first scene information comprises first code stream information and first position information of each first window, the first code stream information represents a code stream corresponding to the first window, and the first position information represents the position of the first window in the display screen. Correspondingly, the second scene information includes second code stream information and second position information of each second window.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating an example provided in an embodiment of the present application. The display screen of the display device 100 may be a single physical display screen, or may be a display screen formed by splicing a plurality of single physical display screens. The display screen of the display device 100 includes a plurality of display areas. As shown in fig. 4, the codestream corresponding to the first window a1 in the first scene is the codestream of IPC 1. For example, if a first window and a second window correspond to the same VO port, it indicates that the first window and the second window are located in the same VO port, i.e., in the same display area.
And a substep S122, obtaining the priority of each first window according to the first code stream information and the first position information of each first window, the second code stream information and the second position information of each second window and a preset priority judgment strategy.
In this embodiment, a preset priority determination policy configured in advance is stored in the display device 100, and after first scene information of a current first scene and second scene information of a second scene are obtained, a priority of each first window is obtained according to the preset priority determination policy based on first code stream information and first position information of each first window in the first scene, and second code stream information and second position information of each second window in the second scene.
Optionally, in this embodiment, the step of obtaining the priority of each first window according to the first code stream information and the first position information of each first window, the second code stream information and the second position information of each second window, and a preset priority determination policy includes:
when the first code stream information of the first window is the same as the second code stream information of the second window, judging that the first window is the first class priority;
and when the first code stream information of the first window is different from the second code stream information of each second window, judging that the first window is in the second category priority.
In this embodiment, a plurality of first windows that need to roam are divided into two category priorities according to corresponding code streams. Optionally, a first window with the first code stream information being the same as second code stream information of a second window is determined as a first class priority; and judging the first window with different first code stream information and different second code stream information of each second window as a second class priority. Because the priority degree of the first category priority is higher than that of the second category priority, when the window roaming is carried out, the first window corresponding to the first category priority is roamed first, and then the second window corresponding to the second category priority is roamed. Therefore, the defects of more used resources and low switching efficiency caused by random roaming of the first window when the window roaming mode is adopted can be avoided.
Further, in an implementation manner of this embodiment, the first category priority may include a first priority, a second priority, a third priority and a fourth priority. The step of determining that the first window is of the first class priority when the first code stream information of the first window is the same as the second code stream information of the second window comprises:
when the first position information of the first window is the same as the second position information of the second window, judging the first window as a first priority;
when the first position information of the first window is different from the second position information of the second window and the display areas corresponding to the first position information of the first window and the second position information of the second window are the same, judging that the first window is of a second priority;
when the first position information of the first window and a part of windows of the second window correspond to the same display area, judging that the first window is of a third priority;
and when the first position information of the first window and the second position information of the second window correspond to different display areas, judging that the first window is in the fourth priority.
In this embodiment, when switching from the first scene to the second scene, if the first code stream information and the first position information of a first window are the same as the second code stream information and the second position information of a second window, it indicates that the code stream and the position of a window are unchanged before and after the scene switching. In this case, the first window is determined as a first priority, and the first window is roamed with the first priority. As shown in fig. 4, the position of the first window a1 in the first scene in the display area 1 is the same as the position of the second window b1 in the second scene in the display area 1, and the first window a1 corresponds to the code stream IPC1, and the second window b1 corresponds to the code stream IPC1, that is, the positions and the code streams corresponding to the first window a1 and the second window b1 are the same. When the above situation exists in the scene switching, the first priority deals with the window and code stream roaming represented by the arrow in fig. 4.
In this embodiment, when switching from the first scene to the second scene, if first code stream information of a first window is the same as second code stream information of a second window, and first position information of the first window is different from second position information of the second window, but a display area corresponding to the first position information of the first window and the second position information of the second window is the same, it indicates that there is a window before and after the scene switching that has the code stream unchanged, the position is different, but the window is in the same display area. In this case, the first window is determined to be of the second priority, and the first window is roamed at the second priority.
Referring to fig. 5, fig. 5 is a second exemplary schematic diagram provided in the embodiment of the present application. As shown in fig. 5, the code streams corresponding to the first window a1 in the first scene and the second window b1 in the second scene are IPC2, and although the specific positions are different, the corresponding display areas are the same and are display area 1. When the above situation exists in the scene switching, the window and stream roaming represented by the arrow in fig. 5 is processed with the second priority.
In this embodiment, when switching from the first scene to the second scene, if first code stream information of a first window is the same as second code stream information of a second window, and first position information of the first window is different from second position information of the second window, but a part of windows of the first window and a part of windows of the second window correspond to the same display area, it indicates that before and after the scene switching, the code stream with the windows is unchanged, but a part of the window information is kept in the same display area. In this case, the first window is determined to be of a third priority, and the first window is roamed with the third priority.
Referring to fig. 6, fig. 6 is a third exemplary schematic diagram provided in the embodiment of the present application. As shown in fig. 6, the display screen includes display areas 1,2, 3, and 4 in order from left to right and from top to bottom. The first window a1 in the first scene corresponds to the code stream IPC3 and corresponds to the display area 1; the second window b1 in the second scene corresponds to the code stream IPC3 and corresponds to the display areas 1 and 2. That is, the first window a1 corresponds to the same code stream IPC3 as the second window b1, and although the specific positions are different, part of the second window b1 remains in the same display area (display area 1) as the first window a 1. When the above situation exists in the scene switching, the window and stream roaming represented by the arrow in fig. 6 is processed with the third priority.
In this embodiment, when switching from the first scene to the second scene, if first code stream information of a first window is the same as second code stream information of a second window, and the first position information of the first window corresponds to a different display area than the second position information of the second window, it indicates that, in the first scene and the second scene, code streams with windows are not changed but are located in different display areas. In this case, the first window is determined to be of a fourth priority, and the first window is roamed at the fourth priority.
Referring to fig. 7, fig. 7 is a fourth exemplary schematic diagram provided in the embodiment of the present application. As shown in fig. 7, the display screen includes display areas 1,2, 3, and 4 in order from left to right and from top to bottom. The first window a1 in the first scene corresponds to the code stream IPC3 and corresponds to the display area 1; the second window b1 in the second scene corresponds to the code stream IPC3 and the display area 2. That is, the first window a1 and the second window b1 correspond to the same code stream IPC3 and are not in the same display area. When the above situation exists in the scene switching, the window and stream roaming represented by the arrow in fig. 7 is processed with the fourth priority.
Further, in an implementation manner of this embodiment, the second category priority may include a fifth priority, a sixth priority, and a seventh priority. The step of judging the first window to be the second category priority when the first code stream information of the first window is different from the second code stream information of each second window comprises the following steps:
when the first position information of the first window and the second position information of the second window correspond to the same display area, judging that the first window is in a fifth priority;
when the first position information of the first window and the second position information of the second window correspond to different display areas and the number of the display areas corresponding to the first position information of the first window is not less than the preset number, judging that the first window has a sixth priority;
and when the first position information of the first window and the second position information of the second window correspond to different display areas, judging that the first window has the seventh priority.
In this embodiment, when switching from the first scene to the second scene, if first code stream information of a first window is different from second code stream information of a second window, and the first position information of the first window corresponds to the same display area as the second position information of the second window, it indicates that there is a change in code stream of the window but the window is located in the same display area in the first scene and the second scene. In this case, the first window is determined as a fifth priority, and the first window is roamed at the fifth priority.
Referring to fig. 8, fig. 8 is a fifth exemplary schematic diagram provided in the embodiments of the present application. As shown in fig. 8, the display screen includes display areas 1,2, 3, and 4 in order from left to right and from top to bottom. The first window a1 in the first scene corresponds to the code stream IPC5 and corresponds to the display area 1; the second window b1 in the second scene corresponds to the code stream IPC6 and corresponds to the display area 1. That is, the first window a1 and the second window b1 correspond to different code streams and different positions, but are both in the display area 1. Therefore, the first windows a1, a2 each correspond to a fifth priority. When the above situation exists in the scene switching, the window and codestream roaming indicated by the arrow in fig. 8 is processed at the fifth priority, that is, the first windows a1 and a2 are processed at the fifth priority.
In this embodiment, when switching from a first scene to a second scene, if first code stream information of a first window is different from second code stream information of a second window, the first position information of the first window and the second position information of the second window correspond to different display regions, and the number of the display regions corresponding to the first position information of the first window is not less than a preset number (for example, 2 or more than 2), it indicates that, in the first scene and the second scene, code streams of windows change, are located in different display regions, and the number of the display regions occupied by the corresponding first window is not less than the preset number. In this case, the first window is determined as a sixth priority, and the first window is roamed with the sixth priority.
Referring to fig. 9, fig. 9 is a sixth exemplary schematic diagram provided in the present application. As shown in fig. 9, the display screen includes display areas 1,2, 3, and 4 in order from left to right and from top to bottom. In the first scene, the first window a1 corresponds to the code stream IPC1, and corresponds to the display areas 3 and 4; the first window a2 corresponds to the code stream IPC2, and correspondingly displays the display areas 1,2, 3 and 4; the first window a3 corresponds to the code stream IPC3 and corresponds to the display areas 1 and 2; the first window a4 corresponds to the code stream IPC4 and the display areas 1 and 3. In the second scene, the second window b1 corresponds to the code stream IPC10, and corresponds to the display area 1; the second window b2 corresponds to the code stream IPC13 and corresponds to the display area 2; the second window b3 corresponds to the code stream IPC12 and corresponds to the display area 3; the second window b4 corresponds to the code stream IPC11 and the display area 4. That is, each first window in the first scene is a window whose code stream changes, whose position is not in the same display area, but whose number of occupied display areas is not less than the preset number. When the above situation exists in the scene switching, the window and stream roaming represented by the arrow in fig. 9 is processed with the sixth priority.
In this embodiment, when switching from a first scene to a second scene, if first code stream information of a first window is different from second code stream information of a second window, and the first position information of the first window corresponds to a different display area than the second position information of the second window, it indicates that there is a change in code stream of the window and the window is not in the same display area in the first scene and the second scene. In this case, the first window is determined as a seventh priority, and the first window is roamed with the seventh priority.
Referring to fig. 10, fig. 10 is a seventh exemplary schematic diagram provided in the embodiment of the present application. As shown in fig. 10, the display screen includes display areas 1,2, 3, and 4 in order from left to right and from top to bottom. The first window a1 in the first scene corresponds to the code stream IPC9 and corresponds to the display area 3, and the second window b1 in the second scene corresponds to the code stream IPC10 and corresponds to the display area 2, that is, the code streams corresponding to the first window a1 and the second window b1 are different, and only one display area and the corresponding display area are respectively corresponding to the first window a1 and the second window b 1. When the above situation exists in the scene switching, the window and stream roaming represented by the arrow in fig. 10 is processed with the seventh priority.
Step S130, sequentially roaming a plurality of first windows corresponding to the number of second windows to the second scene according to the priority of each first window from high to low, so as to complete scene switching.
In this embodiment, after the priority of each window is determined, the plurality of first windows are sequentially roamed into the second scene in the order of priority from top to bottom to switch from the first scene to the second scene. Wherein the priority of the first priority is higher than that of the second priority, the priority of the second priority is higher than that of the third priority, and so on. In the roaming process, if no first window corresponds to the second priority, after all the first windows corresponding to the first priority are roamed, the first windows corresponding to the third priority are roamed.
In this embodiment, if the priorities corresponding to the at least two first windows in the first scene are the same, when roaming the at least two first windows with the same priorities, the at least two first windows are sequentially roamed according to the first location information and the preset location sequence of the at least two first windows. The preset position sequence can be set according to actual requirements.
As shown in fig. 8, the first windows a1, a2 each correspond to a fifth priority. Assuming that the preset position order is from left to right and from top to bottom, when the first window corresponding to the fifth priority is roamed, the first window a1 (i.e. the first window where IPC5 is located) is processed first, and then the first window a2 (i.e. the first window where IPC8 is located) is processed.
Referring to fig. 11, fig. 11 is a flowchart illustrating sub-steps included in step S130 in fig. 2. In this embodiment, when there are a plurality of first windows corresponding to the sixth priority, the step S130 may include a sub-step S131, a sub-step S132, a sub-step S133, a sub-step S134, and a sub-step S135.
And a substep S131, calculating the number of display areas occupied by each first window, and obtaining the roaming order of each first window according to the number of display areas occupied by each first window.
In sub-step S132, before roaming each first window according to the roaming order, a weight value of each display area in the first scene is calculated.
And a substep S133, determining whether the number of second windows in the display area with the minimum current weight value is less than the number of second windows in the display area obtained from the second scene information.
If less, then substep S134 is performed. If not, then substep S135 is performed.
In the sub-step S134, the first window to be roamed is roamed into the display area with the smallest weight value.
In the sub-step S135, the first window to be roamed is roamed into the display area sequentially delayed according to the weight value and the preset position sequence.
In this embodiment, when it is necessary to roam the plurality of first windows corresponding to the sixth priority, the number of display areas occupied by each of the plurality of first windows corresponding to the sixth priority may be counted first, and then the plurality of first windows corresponding to the sixth priority are sorted according to the descending order of the number of display areas occupied, so as to obtain a roaming order of the plurality of first windows corresponding to the sixth priority. Therefore, when roaming, the first window with less display area can be preferentially roamed. Then, before each first window is roamed according to the roaming sequence, the number of the first windows across the display areas in each display area in the current first scene is counted to serve as the weight value of each display area. And finally, obtaining a second window quantity A of each display area in the second scene according to second scene information of the second scene, then obtaining a second window quantity B of each display area in the second scene at the moment, and comparing whether the B of the display area with the minimum current weight value is smaller than A or not. If the window number is smaller than the threshold value, the window number of the display area with the minimum weight value in the second scene is indicated to be less than the threshold value, and a first window to be roamed can be roamed to the display area with the minimum weight value. If the weight value is not less than the first weight value, the number of the windows in the display area with the minimum weight value in the second scene is full, and a first window to be roamed cannot be roamed into the display area with the minimum weight value.
When the number of second windows of the display area with the minimum weight value is full, the display area is extended to the next display area according to the weight values of other display areas in the first scene and preset position information, and when the number of second windows of the next display area is not full, a first window to be roamed is roamed to the extended display area.
The second window quantity A represents the second window quantity of each display area in a preset planned second scene; the second window number B indicates the second window number that each display region in the second scene has when the roaming has proceeded to this point. For example, the number of second windows planned in a display area is 3, and if the number of second windows currently existing in the display area is 2, it indicates that the number of second windows in the display area is not full; and if the number of the second windows in the display area is 3, the second windows in the display area are full.
In the embodiment of the present invention, if there are a plurality of first windows occupying the same number of display areas, that is, the number of display areas occupied by the plurality of first windows is the same, the position and the preset position sequence of each of the plurality of first windows occupying the same number of display areas may be selected, so as to obtain the roaming sequence of the plurality of first windows occupying the same number of display areas. If the minimum weight values are multiple, the number of the second windows in the display areas with the multiple same weight values and the minimum weight values is not full, a display area is selected according to the position of the display area with the minimum weight value and a preset position sequence, and one first window to be roamed is roamed into the display area.
After the roaming of the first window corresponding to the sixth priority is completed, the weight value of each display area in the first scene is recalculated, and the above substeps 133 to S135 are repeated. Until all first windows corresponding to the sixth priority are roamed to completion.
An example of how to roam the first window corresponding to the sixth priority is described below.
Referring to fig. 9 again, the display screen sequentially includes display areas 1,2, 3, and 4 from left to right and from top to bottom. And according to the number of the display areas occupied by the first windows, preferentially roaming the first windows with the least number of the display areas. If a plurality of first windows occupying the least number of display areas exist, the first windows are preferentially roamed according to a preset position sequence from left to right and from top to bottom.
As shown in fig. 9, the first window a1 occupies 2 display regions (display regions 3, 4), the first window a2 occupies 4 display regions (display regions 1,2, 3, 4), the first window a3 occupies 2 display regions (display regions 1, 2), and the first window a4 occupies 2 display regions (display regions 1, 3). Since the first windows a1, a3, a4 occupy the least display area, the first windows a1, a3, a4 are moved first, and then the first window a2 is moved. Since the first window a3 is above, in order from top to bottom and from left to right, the first window a3 (i.e., the first window where IPC3 is located) is preferentially roamed, the second window a4 (i.e., the first window where IPC4 is located) is roamed, the third window a1 (i.e., the first window where IPC1 is located) is roamed, and the fourth window a2 (i.e., the first window where IPC2 is located) is roamed.
As to which display region in the second scene the first window roams, the first window may be preferentially moved to a display region with a smaller weight value according to the weight value of each display region in the first scene. If the weight values of the two display areas in the first scene are equal, the display areas to be roamed to can be selected according to the preset position sequence from left to right and from top to bottom.
When the first window a3 is to be roamed, in the first scene, 3 first windows (a2, a3 and a4) on the display area 1 are across the display area, that is, the weight value of the display area 1 is 3; 2 first windows (a2, a3) on the display area 2 span the display area, namely the weight value of the display area 2 is 2; 3 first windows (a1, a2 and a4) on the display area 3 span the display area, namely the weight value of the display area 3 is 3; there are 2 first windows (a1, a2) on display area 4 that span the display area, i.e., the weight value of display area 4 is 2. Therefore, when the first window a3 is to be roamed, the weight values of the display areas 1-4 in the first scene at this time are: 3,2,3,2.
It is assumed that one window is provided in each display region, which is preset in the second scene based on the second scene information.
When the first window a3 is to be roamed, the weighted values of the display areas 2 and 4 in the first scene are the smallest, and the number of the second windows in the display areas 2 and 4 is 0, that is, the number of the second windows in the display areas 2 and 4 is not full, and then the first window a3 is roamed to the second window b2 in the display area 2 in the second scene based on the preset position sequence from top to bottom and from left to right.
After the first window a3 is moved, the first window a4 is roamed next, at this time, the weight value of each display area in the first scene changes, and the weight values of the display areas 1 to 4 are calculated again when the first window a4 is roamed, and are as follows: 2,1,3,2. At this time, the weight value of the display area 2 in the first scene is the minimum, but the number of the second windows in the display area 2 is 1 at this time, that is, the number of the second windows in the display area 2 is full. In this case, the display areas 1,3, and 4 are selected, and at this time, the weight value of the display area 1 is 2, the weight value of the display area 3 is 3, and the weight value of the display area 4 is 2, so that there are two display areas with the smallest weight values, that is, the display area 1 and the display area 4. The number of second windows in the display area 1 and the display area 4 is 0, and then the second windows can be selected from the display area 1 and the display area 4 in the preset position sequence from left to right and from top to bottom. Since the display area 1 is positioned before the display area 4 in the preset position order, the first window a4 is roamed to the second window b1 of the display area 1 in the second scene.
After the first window a4 is moved, the first window a1 is roamed next, and the updated weight values of the display areas 1-4 in the first scene are: 1,1,2,2. But since the windows of display area 1, display area 2 of the second scene are full, the first window a1 is roamed to the second window b3 of display area 3 of the second scene. Finally the first window a2 is roamed to the second window b4 of the second scene display area 4 in the same way.
As shown above, if the number of windows in the display area of the second scene to be roamed is found to be full in the roaming process, the windows are sequentially continued to the next display area according to the weight value and the preset position sequence from top to bottom and from left to right, and the process is repeated in this way until all the first windows corresponding to the sixth priority have been roamed.
Referring to fig. 12, fig. 12 is a second flowchart illustrating a scene switching method according to an embodiment of the present application. After step S130, the method may further include step S140.
Step S140, after the roaming is finished, if there is a first window that is not roamed in the first scene, closing the first window that is not roamed; or after the roaming is finished, if the number of the first windows is smaller than that of the second windows, windowing is performed in the second scene.
In this embodiment, after the whole roaming process is finished, if it is found that there are any first windows in the first scene where roaming does not occur, the remaining first windows are closed. If all the first windows in the first scene are found to have roamed completely, but windows in the second scene are not windowed, windowing is performed in the second scene.
In the whole scene switching process, the window and the code stream of the first scene are roamed to the place required by the second scene in a roaming mode. After roaming all windows in the first scene according to the second scene information of the second scene, performing the following operations according to the second scene information of the second scene: if the number of the windows of the second scene is not satisfied after all the windows are roamed, newly opening the windows and newly building a code stream; and if redundant windows exist after all the windows are roamed according to the second scene information, closing the redundant windows. Meanwhile, in the window roaming process, the window roaming is carried out according to a certain priority order. The method can reduce resources as much as possible and improve efficiency, thereby ensuring short time and high efficiency of the whole switching process.
