FIG. 1 is a schematic diagram of a multiple window adjustment system according to some embodiments of the invention.
Referring to fig. 1, a multi-window adjustment system 60 according to an embodiment of the present invention is communicatively connected to at least one signal source for controlling a target signal source. According to some embodiments of the present invention, the multi-window adjustment system 60 includes a command screen 10, a splicing processor 21, a switch 50, a terminal 40, and a server 20. According to some embodiments of the invention, the signal source comprises: desktop, camera, notebook computer, panel computer, show accuse all-in-one, touch-sensitive screen, cell-phone etc..
In an embodiment of the present invention, the command screen 10 is used to display a video stream of a target signal source. The conductor screen 10 can include one display device or a plurality of display devices. For example, the command screen 10 of some embodiments of the present invention includes a display or a projector; other embodiments of the present invention include a command screen 10 that includes multiple displays, multiple projectors, or a combination of multiple displays and projectors.
According to some embodiments of the present invention, the stitching processor 21 comprises a video input interface, a video output interface and a network interface.
According to some embodiments of the invention, the stitching processor 21 is communicatively coupled to the command screen 10 via a video output interface.
According to some embodiments of the present invention, the splicing processor 21 is configured to receive the video stream of the signal source through the video input interface, and adjust the video stream of the target signal source according to the control instruction and the target signal source information, and output the adjusted video stream to the command screen 10 through the video output interface (described below). Specifically, the stitching processor 21 of the embodiment of the present invention receives the video streams of the signal source 210, the signal source 220, and the signal source 230 through the video input interface. It should be understood that the number of signal sources that can be received by the embodiments of the present invention is not limited to three, and in practice, a corresponding number of signal sources may be accessed as needed. Taking the signal source as a desktop computer as an example, the display output device interface of the desktop computer may be connected to the video input interface of the stitching processor 21 through a video cable. For example, if the interface of the display output device of the desktop computer is HDMI, and the video input interface of the stitching processor 21 is HDMI, the two are connected by an HDMI video line. It should be understood that the embodiment of the present invention does not limit the type of the video output interface of the signal source, and in practice, the video output interface of the signal source includes HDMI, DVI, VGA, and the like.
The splicing processor 21 of the embodiment of the present invention receives a control instruction and target signal source information of the server 20 through a network interface.
A server 20 configured to be communicatively connected to the splicing processor 21, wherein the server 20 transmits the control instruction and the target signal source information to the network interface of the splicing processor 21. The server 20 may be one server, a server cluster, or a cloud server.
The server 20 is further configured to be connected in communication with a signal source, and configured to obtain a network video stream of the signal source, where the network video stream is obtained by encoding a video stream of the signal source (please refer to fig. 2 specifically).
Fig. 2 is a schematic diagram of a server acquiring a network video stream of a signal source according to some embodiments of the invention.
Referring to fig. 2, the multi-window processing system according to some embodiments of the present invention further includes a screen splitter 220 and a video encoder 230. The screen splitter 220 splits the video output interface of the signal source into multiple paths, and specifically, one path of video stream of the signal source is output to a local display device (not necessary), the other path of video stream of the signal source is output to the stitching processor 21, and the other path of video stream of the signal source is output to the video encoder 230.
The video encoder 230 of the embodiment of the present invention can encode the video stream of the signal source into a network video stream. Therefore, the server of the embodiment of the invention can obtain the network video stream of the signal source. Specifically, the network video stream of the embodiment of the present invention may be a network video stream of h.265. It should be understood that the network video stream may be in other formats as required.
In the multi-window adjustment system according to some embodiments of the present invention, the signal source is communicatively connected to the server 20 in such a way that the signal source outputs a video stream through the video output interface. The video stream output by the signal source is input into the screen splitter 220, one of the video streams is input into the video encoder 230 by the screen splitter 220, the network video stream of the signal source is output after the video encoder 230 encodes the video stream, the network video stream is accessed into the switch 50, the server 20 is accessed into the switch 50, and therefore the server 20 can obtain the network video stream of the signal source.
The command screen 10 can be large in size and can display video streams from hundreds of sources. In an intelligent interactive application environment, the content to be displayed by the command screen 10 can be pre-distributed on the terminal 40, and then the server 20 controls the splicing processor 21, so that the splicing processor 21 displays the corresponding content on the command screen according to the distribution condition on the terminal 40; or vice versa, the display layout on the terminal 40 is synchronized according to the layout situation on the conductor screen. However, the terminal 40 usually adopts a general-purpose electronic device, and the size of the physical display device is limited, so that when the terminal 40 simultaneously displays multiple signal sources, the window corresponding to each signal source is very small, which is not beneficial for the user to pay attention or monitor all or part of the displayed content directly on the terminal 40. To this end, the embodiment of the present invention provides a multi-window adjustment method (see the following description).
Fig. 3 is a schematic diagram of a server acquiring a network video stream of a signal source according to further embodiments of the invention.
In contrast to the previous embodiments of the present invention, the splicing controller 21 and the command screen 10 are omitted in the embodiment shown in fig. 3, other components are the same as those in some embodiments of the present invention, and the same reference numerals are used for the same parts, wherein the terminal 40, the server 20 and the signal source 210, the screen splitter 220 and the video encoder 230 have the same functions as those in fig. 2, but in fig. 3, it is not considered how the target signal source information and the control instruction are transmitted to the splicing controller, and it is not considered how the splicing controller displays the video stream of the corresponding target signal source on the command screen according to the above information.
That is, the multi-window adjusting method provided by the embodiment of the present invention can be performed on the terminal 40 in a system having only the terminal 40, the server 20, and the signal source 210, the screen splitter 220, and the video encoder 230 as shown in fig. 3. Those skilled in the art will understand that the number of signal sources in actual use is one to many. It will also be appreciated by those skilled in the art that when the number of signal sources is plural, one screen splitter and one video encoder may be provided for each signal source. When the signal source is multiple, the server 20 and the terminal 40 can access and acquire one or more network video streams of the signal source. The network video streams of the signal sources all have unique identifications.
When the network video streams corresponding to the plurality of signal sources are played on the terminal 40, the size of the display device of the terminal 40 is usually smaller, and it is inconvenient for a user to view the plurality of network video streams on the terminal 40 with the smaller display size.
Fig. 4 is a flow chart of a multi-window adjustment method of some embodiments of the invention.
As shown in fig. 4, the flowchart of the multi-window adjustment method of the embodiment of the present invention includes steps 100-400, which are performed by the terminal 40 in conjunction with information from other components.
Step 100, generating a total window, and drawing each window on the total window.
In embodiments of the present invention, the summary window covers or draws all of the content available for display.
Since the physical display device size is fixed, when there are many windows on the total window, each window is very small in order to monitor multiple windows simultaneously. According to some embodiments of the invention, the size of the total window is larger than the size of the physical display device. When there are many windows in the embodiment of the present invention, a part of the total window is displayed so that each window can be presented on the physical display device in a user-friendly size.
According to some embodiments of the present invention, an overall window may be generated according to a predetermined aspect ratio. For example, the generated total window may be a total window having a height greater than a width; or, the generated total window is a total window with a width larger than a height; alternatively, the total window generated is one of equal height and width. In an embodiment of the present invention, the height may represent a dimension of the overall window in a vertical direction, and the width may represent a dimension of the overall window in a horizontal direction.
According to some embodiments of the present invention, the shape of the overall window is not limited to a rectangle, and the shape of the overall window may be other shapes, for example, a regular shape or an irregular shape.
According to some embodiments of the present invention, the drawing of each window on the total window includes two substeps, step 110 and step 120.
And step 110, acquiring window information of each window and signal source information pre-associated in the window.
According to some embodiments of the invention, the window information includes an upper left vertex coordinate of the window, a width of the window, and a height of the window.
The position of the window and the size of the window can be determined on the total window according to the window information. For example, the window is first positioned on the overall window based on the top left vertex coordinates, and the size of the window is determined based on the width of the window and the height of the window. When the total window includes a plurality of windows, the window information further includes a window map layer value. Therefore, when the shielding condition exists between the windows, the stacking sequence or the shielding condition of the windows is determined according to the window map layer value.
In the multi-window adjusting method of the embodiment of the invention, pre-associated signal source information in the window is obtained. In some embodiments of the invention, the signal source information comprises a signal source identification. In some embodiments of the present invention, the signal source information further includes a signal source address, a port number, or a signal source type. The signal source Address in the embodiment of the present invention may be an IP Address (Internet Protocol Address).
In some embodiments of the present invention, the signal source may be a local signal source or a remote signal source.
According to some embodiments of the invention, the window information for each window may also be obtained over a network. That is, the window information of each window is obtained through the network, and the appearance of each window is drawn on the total window according to the obtained window information of each window. The network may be a local area network or a wide area network. For example, window information for each window, as well as pre-associated signal source information within the window, may be obtained from server 20. According to some embodiments of the present invention, window information for each window is obtained in real time over a network.
And step 120, drawing each window on the total window.
Step 120 comprises two substeps, step 121 and step 122, respectively.
And 121, drawing the appearance of each window according to the window information of each window.
Specifically, the appearance of each window is drawn on the total window according to the window information. According to some embodiments of the present invention, the window information of each window may be obtained by receiving data input by a user, that is, the window information of each window is specified by the user, for example, the coordinates of the top left vertex of each window, the width of each window, and the height of each window are specified by the user, and then the appearance of each window is drawn on the total window according to the window information specified by the user.
And step 122, drawing the video stream in each window according to the signal source information in each window.
Step 122 includes two substeps, step 1221 and step 1222, respectively.
And 1221, acquiring an image frame of the signal source according to the signal source information.
Specifically, in each window, an image frame of the signal source is acquired according to the signal source information of the window.
Step 1222, render the image frame as a video stream within a window.
Specifically, the image frames of the signal source are rendered as a video stream within a window.
According to some embodiments of the invention, the rendering of the appearance of each window in step 121 and the rendering of the video stream within each window in step 122 may be real-time rendering. That is, in each update period, the appearance of each window is redrawn according to the window information, and the video stream in each window is redrawn according to the signal source information in each window.
According to some embodiments of the invention, drawing the appearance of each window in step 121 may redraw the window appearance only when the window information changes. That is, when the window position is changed, the window size is adjusted, and the layer value of the window is changed, the window appearance is redrawn. At this point, the rendering of the video stream within the window by step 122 remains in real-time.
Step 200, acquiring interactive data, and updating the display effect of the total window on the screen according to the interactive data to obtain the current viewport.
According to some embodiments of the invention, the interaction actions associated with (or based on) the interaction data of embodiments of the invention include: move the overall window, zoom in on the overall window, and/or zoom out on the overall window. For example, the total window is moved by a first operation of the mouse, enlarged by a second operation of the mouse, and reduced by a third operation of the mouse. Specifically, the first operation may be clicking and dragging, the second operation may be sliding the wheel upward, and the third operation may be sliding the wheel downward. Further, the enlarging of the total window specifically includes enlarging the total window with a predetermined position as a reference. The reducing of the total window specifically includes reducing the total window with reference to a predetermined position. In an embodiment of the present invention, the predetermined positions comprise: the current position of the mouse is taken as a preset position, and/or the central position of the general window is taken as a preset position.
According to some embodiments of the invention, the viewport location is fixed. That is, the view port of the embodiment of the present invention is located in a fixed area of the physical display device.
In order to display a part of the porthole in the embodiment of the present invention, the visible area may be set as a portion where the viewport overlaps with the porthole.
FIG. 5 is a schematic illustration of a summary window according to some embodiments of the inventions.
As shown in FIG. 5, the summary window 1000 is the entire content available for display. One or more windows may be created on the overall window 1000. For example, window 101, window 102, window 103, and window 104 are created on top of the general window 1000. It should be understood that the number of windows in the embodiment of the present invention is not limited to 4, and a corresponding number of windows may be created according to the use case. For example, the corresponding window is created according to the number of signal sources.
According to some embodiments of the present invention, the windows may be arranged in a tiled arrangement, in a stacked arrangement, in a spaced arrangement, and in an irregular arrangement. The positions of the windows and the positional relationship between the windows can be obtained in step 121, and are not described herein again.
According to some embodiments of the invention, the size of the windows may be the same or may be completely different. The size of the window can also be obtained in step 121, which is not described herein again.
Fig. 6 is a schematic diagram of a viewport in accordance with some embodiments of the invention.
The size of the viewport is smaller than the total window. The viewport is used to display a part of the overview window, i.e. which part of the overview window the viewport displays is changed in real time in dependence of the interaction data. For example, when the user drags the mouse, a first operation is generated, and the first operation acts on the porthole 1000, so that the relative positions of the porthole 1000 and the viewport 2000 are changed. When the user slides the wheel upward, a second operation is generated, which acts on the porthole 1000 such that the porthole 1000 is enlarged with respect to the viewport 2000. When the user slides the scroll wheel downward, a third operation is generated, and the third operation acts on the global window 1000, so that the global window 1000 is reduced relative to the viewport 2000. Thereby causing the content of the viewport 2000 to be rendered on the physical display device of the terminal 40 after updating in accordance with the interaction data.
Referring to fig. 6, fig. 6 is the content currently displayed by the viewport. That is, when the user wants to focus on window 101 and window 102, the user can interact with the mouse, generate interaction data, and adjust the total window using the interaction data, so that only window 101 and window 102 are displayed in viewport 2000, thereby focusing on both windows. In an embodiment of the invention, the content displayed by the viewport is updated in real time according to the interaction data. For example, in some embodiments of the present invention, a user operating a mouse generates interaction data such that the position or size of the porthole changes, whereby the relative size and relative position of the viewport and the porthole changes, updating the viewport in real time.
And step 300, creating a preview window of the total window as a first preview window.
With continued reference to FIG. 6, first preview window 3000 is created in accordance with some embodiments of the present invention. First preview window 3000 is created according to general window 1000, and specifically, first preview window 3000 may be created after general window 1000 is reduced.
Step 400, creating a rectangular frame on a first preview window, linking the rectangular frame with the current viewport, and updating the current viewport according to the interaction of the rectangular frame, wherein the interaction data includes interaction data generated by the interaction of the rectangular frame.
With continued reference to FIG. 6, according to some embodiments of the present invention, a rectangular box 4000 is created on first preview window 3000, wherein the rectangular box is created from viewport 2000. Specifically, when the user zooms in, zooms out, or moves the global window through the interactive data in step 200, the size and position of the viewport are fixed, and the global window changes, so that the viewport is updated according to the interactive data, that is, in the embodiment of the present invention, the rectangular frame 4000 is linked with the viewport 2000.
According to some embodiments of the present invention, the current viewport 2000 may be updated according to the interaction with the rectangular box 4000. According to some embodiments of the invention, interactive data of the user moving the rectangular frame is obtained; changing the positional relationship of the total window and the current viewport according to the interaction data; and updating the current viewport according to the position relation of the changed total window and the current viewport.
The technical scheme of the embodiment of the invention generates a total window and draws each window on the total window; acquiring interactive data, and updating the display effect of the total window on the screen according to the interactive data to obtain a current viewport; creating a preview window of the total window as a first preview window; creating a rectangular frame on a first preview window, and linking the rectangular frame with the current viewport; wherein the rectangular box is also capable of generating the interaction data to update the current viewport. Therefore, the multi-window adjusting method provided by the embodiment of the invention is convenient for a user to quickly and efficiently monitor and adjust the multi-window.
