All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Example 1
According to the embodiments of the present application, there is provided an embodiment of a control method of a screen display, it should be noted that the steps shown in the flowcharts of the drawings may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be executed in an order different from that herein.
Fig. 1 is a flowchart of a control method of a screen display according to an embodiment of the present application, as shown in fig. 1, the method including the steps of:
step S102, receiving a rotation instruction.
Specifically, the rotation instruction may be sent by a user operating on a man-machine interaction interface displayed on the screen, or may be sent by a user operating on a remote controller for controlling the screen, or may be sent by a user on another control device in communication with the screen, for example, a mobile terminal in communication with the screen, or the like.
In an alternative embodiment, the user can call up the control interface displayed on the screen by operating the screen, wherein the control interface comprises a plurality of control controls for the screen, at least comprises a rotation control, and the user selects the rotation control in the control interface, so that a rotation instruction can be sent to the screen. At this time, the screen receives a rotation instruction through the touch control component thereof.
In another alternative embodiment, the remote controller of the user control screen has a rotation control, and the user can select the rotation control by operating the remote controller, so as to give a rotation instruction to the screen. At this time, the screen receives the rotation instruction through the infrared signal.
In yet another alternative embodiment, the screen may be in communication with a mobile terminal, and the screen may be controlled by the mobile terminal. In such an example, a user may operate on the mobile terminal to send a rotation instruction to the screen. At this time, the screen receives the rotation instruction by bluetooth, wireless, or the like.
When a user of the screen needs to play the multimedia content by erecting the screen, but the screen is fixedly configured to be in a horizontal screen size when leaving the factory, in order to avoid the complicated operation of re-configuring the screen, the user can send a rotation instruction to the screen so as to realize the effect of playing the screen by erecting the screen on the screen with the horizontal screen. Similarly, when the user of the screen needs to play the multimedia content on the horizontal screen and the screen is already matched to the vertical screen size when leaving the factory, in order to avoid the complicated operation of re-configuring the screen, the user can send a rotation instruction to the screen so as to realize the effect of playing the horizontal screen on the screen with the vertical screen.
Step S104, the playing window is rotated according to the rotation instruction, and whether the size information of the playing window is adjusted is judged.
Specifically, the above-mentioned play window may be created by a transmission card, which may be provided in a multimedia box. In the process of displaying the screen, a sending card creates a playing window according to the screen matching size, each frame of video memory picture is transmitted to an FPGA (Field Programmable Gate Array ) module, after the FPGA module intercepts the picture of the playing window according to the preset screen matching size, interface data are transmitted to a receiving card, and the screen is displayed according to the image received by the receiving card.
Fig. 2 is a schematic diagram of a multimedia box for processing a display image, where the multimedia box includes a transmitting card and an FPGA module, each frame of video memory picture sent from the transmitting card to the receiving card is a full resolution picture, and the FPGA intercepts a frame of the picture from the upper left corner according to a preset screen allocation size, and then transmits the frame of the picture to the receiving card, and the frame of the picture is displayed by a screen.
In the above scheme, the sending card does not directly send to the FPGA module for interception after creating the play window, but sends to the FPGA module for interception after judging whether to adjust the size information of the play window according to the rotation instruction.
The playing window is used for carrying images, and if the playing window is not matched with the screen matching size of the equipment after rotation, all contents in the playing window are difficult to display, so that the display effect after rotation is poor. Therefore, after the playing window is rotated, it is further required to determine whether the size information of the playing window needs to be adjusted, so that the rotated playing window can be matched with the screen matching size of the device.
In an alternative embodiment, where the screen is rectangular, the size information of the playback window comprises two parts, namely a length and a width, the length and the width of the playback window need not be changed if the rotation angle indicated in the rotation instruction is 180 °, and the length and the width of the playback window need to be adjusted if the rotation angle indicated in the rotation instruction is 90 °, or 270 °.
Step S106, if the judgment result is yes, the size information of the playing window is adjusted, and the redrawn display image in the adjusted playing window is transmitted to a screen for display, wherein the redrawn display image in the playing window is carried out after the size information of the playing window is adjusted.
When the rotation angle indicated in the rotation instruction is 90 degrees or 270 degrees, the length and the width of the display screen after rotation are exchanged, and the intercepted size and the position of the FPGA are fixed when the intercepted display screen is sent to the screen for display, so that in order to enable the FPGA to completely intercept the display screen in the display window, the size information of the display window also needs to be adjusted so as to enable the size information of the display window to be matched with the size information intercepted by the FPGA, and therefore the size information of the display window is unchanged, but the effect of rotating the display image in the display window is achieved.
After the size information of the play window is adjusted, the display image in the play window is rotated by redrawing due to the previous rotation of the play window. In an alternative embodiment, the image in the playing window generally includes multiple layers, and when redrawing, the layers are sequentially drawn from low to high, that is, the layer at the bottom layer is drawn first, and then the layers at the upper layer are sequentially drawn until each layer in the playing window is drawn. Before the display image is redrawn, the position of each sub-layer in the image on the parent layer is required to be recorded, wherein the sub-layer is positioned above the parent layer, after the parent layer is drawn, the position of the sub-layer on the parent layer is recalculated, so that the sub-layer is drawn, similar calculation is sequentially carried out until all the layers are redrawn.
In this embodiment, the sequence of step S104 and step S106 is not limited, and the play window may be rotated first, and then the size information of the play window may be adjusted, or the size information of the play window may be adjusted first, and then the play window may be rotated. And the step of redrawing the display image is performed after rotating the play window and adjusting the size information of the play window.
And under the condition that the size information of the playing window needs to be adjusted, after the size information of the playing window is adjusted, the playing window is matched with the size of the matched screen. At this time, the transmitting card transmits the image in the playing window to the receiving card, and the screen displays the display image received by the receiving card, thereby completing the rotation operation.
In an alternative embodiment, when the user of the screen needs to play the multimedia content with the vertical screen, but the screen is already configured to be in the horizontal screen size when shipped, the user may send a rotation instruction rotated by 90 ° to the screen, so that the played image can be displayed with the vertical screen on the screen. FIG. 3 is a schematic diagram of a screen having been cross-screen paired for cross-screen display of images in conjunction with the screen shown in FIG. 3, according to an embodiment of the present application. The user needs to display the image on the vertical screen, so that a rotation instruction is sent to the screen, and the sending card matched with the screen can execute the steps, so that the rotation of the image is completed. The sending card transmits the display image in the adjusted playing window to the FPGA module, the FPGA module intercepts the image in the playing window and sends the image to the receiving card, and the receiving card transmits the display image to the screen, so that the display can be displayed on the screen in a vertical screen.
It should be noted that if the FPGA module rotates, the FPGA module only rotates the frame, and the frame with the horizontal screen size is stretched to fill the vertical screen size, or the frame with the vertical screen size is compressed to fill the window with the horizontal screen size, so that the method is only suitable for still pictures without special effects, has poor multimedia display effects on dynamic characters, and cannot realize automatic layout from the horizontal screen to the vertical screen. In the above scheme in this embodiment, the sending card adjusts the size information of the playing window, so that stretching or compression of the image is not required, and the display effect of the image can be ensured.
As can be seen from the above, the above embodiments of the present application receive a rotation instruction; rotating the playing window according to the rotation instruction, and judging whether to adjust the size information of the playing window; if the judgment result is yes, the size information of the playing window is adjusted, and the display image in the adjusted playing window is transmitted to a screen for display, wherein the display image in the playing window is redrawn after the size information of the playing window is adjusted. According to the scheme, the playing window is rotated, and the size information of the playing window is adjusted according to the rotation instruction, so that the configured LED screen can be directly applied only by rotating and automatically distributing the playing window without carrying out hardware wiring again and modifying screen matching software parameters, the effect of randomly switching the horizontal screen and the vertical screen is achieved, and the problem that screen matching needs to be carried out again when the directions of the LED screen and the display picture which are completed by screen matching in the prior art are not matched is solved.
As an alternative embodiment, the rotation instruction includes a rotation angle and/or a rotation direction, and rotating the original image in the playing window according to the rotation instruction includes at least one of the following: controlling the original image in the playing window to rotate according to the rotation angle indicated in the rotation instruction; and controlling the playing window to rotate according to the rotation direction indicated in the rotation instruction.
Specifically, the above-described rotation angle may be a rotation angle with respect to the original image. The rotation angle here may be a multiple of 90 °, for example: 90 °, 180 ° and 270 °.
In an alternative embodiment, 90 °, 180 ° and 270 ° each correspond to one state, and when the user selects 90 ° rotation, the image assumes a state corresponding to 90 °, and when the user selects 180 ° again, the image is not rotated 180 ° on the basis of the rotated 90 ° but is rotated again to a state corresponding to 180 ° on the basis of the original state. On a man-machine interaction interface provided for a user, "90 °", "180 °", "270 °", which can be selected by the user according to the requirements, can be displayed.
In another alternative embodiment, the user may make visual selections by displaying the display effect rotated according to each rotation angle without prompting an explicit rotation angle on a human interactive interface provided for the user.
In the scheme, the rotation angle is set in the rotation instruction, so that the image can rotate according to the appointed rotation angle, and the requirement of a user on screen rotation is met at one time.
The above-described rotation direction is a specified direction, for example, a clockwise rotation, and each rotation instruction is a clockwise rotation based on the original image.
In another alternative embodiment, the above rotation direction may be specified by the user, and matching different rotation directions for the same rotation angle may have different rotation effects, so that the user may control the image to rotate in different directions according to the actual display requirement.
As an alternative embodiment, the rotation angle is used to indicate the angle of the rotated play window relative to the non-rotated play window, and the rotation angle includes: 90 °, 180 °, 270 °, wherein the step of determining whether to adjust the size information of the play window includes: if the rotation angle is 90 degrees or 270 degrees, determining the size information of the play window to be adjusted; if the rotation angle is 180 DEG, the size information of the play window is determined not to be adjusted.
In the above scheme, if the rotation angle is 90 ° or 270 °, the image displayed by the original vertical screen is rotated to be displayed by the horizontal screen, or the image displayed by the original horizontal screen is rotated to be displayed by the vertical screen, and obviously, when the size of the matched screen is not square, such rotation can cause the length information and the width information of the playing window to be exchanged, so that the size information of the playing window needs to be adjusted. According to the scheme, the size information of the playing window is adjusted when the rotation angle is 90 degrees or 270 degrees, so that the playing window can correspond to a display image after rotation.
And if the rotation angle is 180 degrees, the image displayed by the original vertical screen is still displayed by the vertical screen after rotation, and the image displayed by the original horizontal screen is still displayed by the horizontal screen after rotation, obviously, in this case, the size information of the original playing window is matched with the size information of the playing window after rotation, so that the size information of the playing window does not need to be adjusted.
As an alternative embodiment, if the judgment result is that the size information of the playing window is not adjusted, redrawing the display image in the rotated playing window, and transmitting the redrawn display image to the screen for display.
In the above scheme, if the judgment result is that the size information of the playing window is not adjusted, the display image in the rotated playing window can be directly redrawn, and the redrawn display image is output to the receiving card for displaying on the screen.
The manner of redrawing the display image in the rotated play window is the same as the manner of redrawing the display image in the play window after the size information is adjusted, and will not be described here again.
In an alternative embodiment, the user is unfamiliar with the installation of the screen flat cable, and installs the screen upside down, so that the display of the image is inverted, in order not to detach and install the screen again, the user can control the image to rotate 180 ° so that the image of the screen can be seen forward when watching the screen, in this case, the size information of the playing window is not adjusted, and after the display image in the rotated playing window is directly redrawn, the redrawn display image is transmitted to the receiving card, and the screen is displayed.
As an alternative embodiment, the size information includes a first length of the play window in a first direction of the play plane, and a second length of the play window in a second direction of the play plane, wherein the first direction is perpendicular to the second direction, and adjusting the size information of the play window includes: determining the first length of the play window before adjustment as the second length of the play window after adjustment; and determining the second length of the play window before adjustment as the first length of the play window after adjustment.
Specifically, the first direction and the second direction of the playing plane may be a vertical direction and a horizontal direction, and the first length of the first direction and the second length of the second direction are a length and a width, respectively.
In an alternative embodiment, the image in the playing window is rotated by 90 °, and in order to match the image, the playing window adjusts the original width to the current length and adjusts the original length to the current width, so as to adjust the playing window, and the adjusted playing window corresponds to the image.
As an alternative embodiment, transmitting the redrawn display image in the adjusted play window to the receiving card includes: and sending the redrawn display image in the adjusted playing window to a logic processing module, wherein the logic processing module intercepts the display image in the playing window according to a preset size and sends the intercepted display image to a receiving card.
Specifically, the logic processing module may be an FPGA module, configured to intercept the playing window.
In the above scheme, the sending card sends the display image in the playing window to the logic processing module, the logic processing module intercepts the display image in the playing window according to the size of the matched screen, and sends the intercepted image to the receiving card, and the screen displays the image according to the image received by the receiving card, so that the rotation of the image is completed.
As an alternative embodiment, before transmitting the redrawn display image in the adjusted playing window to the screen for display, the method further includes: the redrawing of the display image in the play window after the size information of the play window is adjusted specifically comprises the following steps: acquiring the relative position of each sub-layer on a parent layer in an unrotated play window, wherein the parent layer is the next layer adjacent to the sub-layer; and sequentially drawing each layer according to the relative position of each sub-layer on the parent layer according to the sequence from low to high of the layers by taking the play window with the size information adjusted as the root layer of the bottommost layer until all the layers are drawn.
In the above scheme, the playing window includes multiple layers, the playing window is the root layer of the layers, the rotation of the playing window is the rotation of the root layer, and after the playing window rotates, the display image is redrawn. When re-drawing, the layers are sequentially drawn from low to high, namely, the layer at the bottom layer is drawn firstly, and then the layers at the upper layer are sequentially drawn until each layer in the playing window is drawn.
Specifically, before drawing, the relative position of each sub-layer in the image on the parent layer is required to be recorded, after the parent layer is drawn, the position of the sub-layer on the parent layer is recalculated according to the position of the pre-recorded sub-layer on the parent layer, so that the sub-layer is drawn, and similar calculation is sequentially performed until all the layers are drawn.

Example 3
According to an embodiment of the present application, there is provided an embodiment of a control system for screen display, and fig. 5 is a schematic diagram of a control system for screen display according to an embodiment of the present application, and in combination with fig. 5, the system includes:
the sending card 50 receives the rotation instruction, rotates the playing window according to the rotation instruction, judges whether to adjust the size information of the playing window, if so, adjusts the size information of the playing window after rotation, and transmits the display image in the playing window after adjustment to the receiving card, wherein the display image in the playing window is redrawn after the size information of the playing window is adjusted;
a receiving card 52 for receiving the display image sent by the sending card and transmitting the redrawn display image to the screen;
and a screen 54 for displaying a display image transmitted from the receiving card.
Specifically, the rotation instruction may be sent by a user operating on a man-machine interaction interface displayed on the screen, or may be sent by a user operating on a remote controller for controlling the screen, or may be sent by a user on another control device in communication with the screen, for example, a mobile terminal in communication with the screen, or the like.
In an alternative embodiment, the user can call up the control interface displayed on the screen by operating the screen, wherein the control interface comprises a plurality of control controls for the screen, at least comprises a rotation control, and the user selects the rotation control in the control interface, so that a rotation instruction can be sent to the screen. At this time, the screen receives a rotation instruction through the touch control component thereof.
In another alternative embodiment, the remote controller of the user control screen has a rotation control, and the user can select the rotation control by operating the remote controller, so as to give a rotation instruction to the screen. At this time, the screen receives the rotation instruction through the infrared signal.
In yet another alternative embodiment, the screen may be in communication with a mobile terminal, and the screen may be controlled by the mobile terminal. In such an example, a user may operate on the mobile terminal to send a rotation instruction to the screen. At this time, the screen receives the rotation instruction by bluetooth, wireless, or the like.
When a user of the screen needs to play the multimedia content by erecting the screen, but the screen is fixedly configured to be in a horizontal screen size when leaving the factory, in order to avoid the complicated operation of re-configuring the screen, the user can send a rotation instruction to the screen so as to realize the effect of playing the screen by erecting the screen on the screen with the horizontal screen. Similarly, when the user of the screen needs to play the multimedia content on the horizontal screen and the screen is already matched to the vertical screen size when leaving the factory, in order to avoid the complicated operation of re-configuring the screen, the user can send a rotation instruction to the screen so as to realize the effect of playing the horizontal screen on the screen with the vertical screen.
The above-mentioned play window may be created by a transmission card, which may be provided in a multimedia box. In the process of displaying the screen, a sending card creates a playing window according to the screen matching size, each frame of video memory picture is transmitted to an FPGA (Field Programmable Gate Array ) module, after the FPGA module intercepts the picture of the playing window according to the preset screen matching size, interface data are transmitted to a receiving card, and the screen is displayed according to the image received by the receiving card.
Fig. 2 is a schematic diagram of a multimedia box for processing a display image, where the multimedia box includes a transmitting card and an FPGA module, each frame of video memory picture sent from the transmitting card to the receiving card is a full resolution picture, and the FPGA intercepts a frame of the picture from the upper left corner according to a preset screen allocation size, and then transmits the frame of the picture to the receiving card, and displays the frame of the picture on a screen.
In the above scheme, after the playing window is created by the sending card, the sending card is not directly sent to the FPGA module for interception, but after the playing window is rotated according to the rotation instruction, whether the size information of the playing window is adjusted is judged, and then the playing window is sent to the FPGA module for interception.
The playing window is used for carrying the image, and if the playing window is not matched with the display image after rotation, it is difficult to display all contents through the playing window, so that the display effect after rotation is poor. Therefore, after the play window is rotated, it is also necessary to determine whether the size information of the play window needs to be adjusted.
In an alternative embodiment, where the screen is rectangular, the size information of the playback window comprises two parts, namely a length and a width, the length and the width of the playback window need not be changed if the rotation angle indicated in the rotation instruction is 180 °, and the length and the width of the playback window need to be adjusted if the rotation angle indicated in the rotation instruction is 90 °, or 270 °.
And under the condition that the size information of the playing window needs to be adjusted, after the size information of the playing window is adjusted, the playing window is matched with the displayed image. At this time, the transmitting card transmits the image in the playing window to the receiving card, and the screen displays the display image received by the receiving card, thereby completing the rotation operation.
In an alternative embodiment, when the user of the screen needs to play the multimedia content with the vertical screen, but the screen is already configured to be in the horizontal screen size when shipped, the user may send a rotation instruction rotated by 90 ° to the screen, so that the played image can be displayed with the vertical screen on the screen. FIG. 3 is a schematic diagram of a screen having been cross-screen paired for cross-screen display of images in conjunction with the screen shown in FIG. 3, according to an embodiment of the present application. The user needs to display the image on the vertical screen, so that a rotation instruction is sent to the screen, and the sending card matched with the screen can execute the steps, so that the rotation of the image is completed. The sending card transmits the display image in the adjusted playing window to the FPGA module, the FPGA module intercepts the image in the playing window and sends the image to the receiving card, and the receiving card transmits the display image to the screen, so that the display can be displayed on the screen in a vertical screen.
It should be noted that if the FPGA module rotates, the FPGA module only rotates the frame, and the frame with the horizontal screen size is stretched to fill the vertical screen size, or the frame with the vertical screen size is compressed to fill the window with the horizontal screen size, so that the method is only suitable for still pictures without special effects, has poor multimedia display effects on dynamic characters, and cannot realize automatic layout from the horizontal screen to the vertical screen. In the above scheme in this embodiment, the transmitting card rotates the image and adjusts the size information of the playing window, so that stretching or compression of the image is not required, and the display effect of the rotated image can be ensured.
As can be seen from the above, the control system for screen display in the above embodiments of the present application receives a rotation instruction through the receiving card; rotating the playing window according to the rotating instruction, and judging whether to adjust the size information of the playing window; if the judgment result is yes, the size information of the playing window is adjusted, and the display image in the adjusted playing window is transmitted to the receiving card, wherein the screen displays the display image received by the receiving card. According to the scheme, the playing window is rotated, and the size information of the playing window is adjusted according to the rotation instruction, so that the configured LED screen can be directly applied only by rotating and automatically distributing the playing window without carrying out hardware wiring again and modifying screen matching software parameters, the effect of randomly switching the horizontal screen and the vertical screen is achieved, and the problem that screen matching needs to be carried out again when the directions of the LED screen and the display picture which are completed by screen matching in the prior art are not matched is solved.
As an alternative embodiment, the system includes: the logic controller is connected between the sending card and the receiving card, and is used for intercepting the display image in the playing window according to the preset size and sending the intercepted display image to the receiving card.
