For the convenience of the reader's understanding, the following is a brief explanation of the concept of a window:

the window is a carrier for image rendering, and is usually displayed as a rectangle on a television wall, the window is associated with an input source device, and a picture played in a certain window is a video image corresponding to a video code stream provided by the input source device associated with the window. The window can be displayed at any position on the television wall according to actual configuration requirements, the size of the window cannot exceed the size of the television wall to the maximum, and the minimum size is generally not smaller than a preset size minimum value, for example, 64 × 64 pixels.

For example, when a distributed large screen controller is used, the upper limit of the number of windows displayed on the television wall is related to the maximum number of decoding paths supported by the C20N output box, e.g., the upper limit of the number of windows displayed on the television wall is 4 if the C20N output box supports four decoding paths at maximum.

And step 304, sending the k video code streams to the terminal so that the terminal can correspondingly display video images corresponding to the k video code streams in the m second windows.

To sum up, in the pre-monitoring display method provided in the embodiments of the present invention, after receiving the pre-monitoring request sent by the terminal, the main control server may receive n video code streams sent by the input source device corresponding to the target television wall based on the identification information of the target television wall, and determine k video code streams for displaying in m first windows of the target television wall among the n video code streams based on the identification information of the k input source devices, and then send the k video code streams to the terminal, so that the terminal correspondingly displays video images corresponding to the k video code streams in m second windows, because the m second windows on the display interface of the terminal correspond to the m first windows on the target television wall one to one, and the video images displayed in the m second windows of the terminal are the same as the video code streams corresponding to the video images displayed in the m first windows of the target television wall, therefore, when the video images corresponding to the k video code streams are displayed in the m second windows on the display interface of the terminal, the display interface of the terminal is consistent with the picture displayed on the display interface of the target television wall, and a technician can confirm the configuration condition of the television wall by watching the display interface of the terminal.

Optionally, when the pre-monitoring display method provided in the embodiment of the present invention is applied to the pre-monitoring display system shown in fig. 1A, in step 201, the method for the terminal to obtain k video streams for display in m first windows of the target television wall may include:

s11, acquiring n video code streams provided by n input source devices corresponding to the target television wall, wherein n is a positive integer.

Optionally, the terminal may be directly connected to n input source devices corresponding to the target television wall, and when the target television wall is configured, the n input source devices simultaneously provide video code streams to the terminal and the target television wall.

And S12, determining k input source devices corresponding to the m second windows, wherein k is more than or equal to 1 and less than or equal to n.

And S13, determining k video code streams corresponding to the k input source devices in the n video code streams.

Correspondingly, in step 202, the obtaining, by the terminal, the position information of the video images corresponding to the k video streams may include: the position information is determined based on the window information of the m first windows.

In practical applications, in order to reduce the operation burden of the terminal and reduce the performance requirement on the processor of the terminal, the main control server is usually adopted to process the video code stream provided by the input source device, the following embodiments of the present invention describe in detail the process of applying the pre-monitoring display method to the pre-monitoring display system shown in any one of fig. 1B to fig. 1D, fig. 4 is a flowchart of another pre-monitoring display method provided by an embodiment of the present invention, and as shown in fig. 4, the method may include:

step 401, when the terminal prepares to configure the target video wall, a communication connection is established with the master control server according to the address and the access port of the master control server.

Optionally, the terminal may establish a communication connection with the main control server through a wired network or a wireless network.

Step 402, the terminal sends a pre-monitoring request to the master control server.

The pre-monitoring request can include identification information of the target television wall and identification information of k input source devices, which are determined by the terminal and correspond to m second windows on a display interface of the terminal, wherein m and k are positive integers. The terminal may store identification information of all input source devices corresponding to the target television wall, and determine k input source devices corresponding to the m second windows according to the received instruction.

Optionally, the m second windows may correspond to the k input source devices one to one, that is, each second window may be used to display a video image corresponding to a video stream provided by one input source device.

It should be noted that, an input source device may provide a video code stream, and the number of the second windows may be greater than the number of the video code stream, for example, when a window division operation is performed on the second window, at least two windows obtained after division jointly display video images corresponding to the same video code stream; the number of the second windows may also be smaller than the number of the video code streams, for example, when the window closing operation is performed on the second windows, the number of the second windows is smaller than the number of the video code streams; the number of the second windows may also be equal to the number of the video code streams, which is not limited in the embodiment of the present invention.

Step 403, the main control server receives n video code streams sent by the input source device corresponding to the target television wall based on the identification information of the target television wall.

And k is more than or equal to 1 and less than or equal to n, optionally, the master control server can support multiple television walls, and the master control server stores the corresponding relation between each television wall and the input source equipment in advance. For example, a video wall identified as 1 corresponds to 3 input-source devices identified as a1, a2, and a3, respectively, and a video wall identified as 2 corresponds to 4 input-source devices identified as b1, b2, b3, and b4, respectively.

After receiving the pre-monitoring request, the main control server may determine n input source devices corresponding to the target television wall according to the corresponding relationship between the television wall and the input source devices based on the identification information of the target television wall, and receive n video code streams sent by the n input source devices.

Optionally, after receiving the pre-monitoring request, the main control server may detect whether the target television wall meets the pre-monitoring condition based on the identification information of the target television wall; and after the target television wall is determined to meet the pre-monitoring condition, receiving n video code streams sent by input source equipment corresponding to the target television wall.

Further, the main control server may send pre-monitoring failure information to the terminal after determining that the target television wall does not satisfy the pre-monitoring condition, where the pre-monitoring failure information is used to indicate that the terminal cannot pre-monitor the video image displayed on the target television wall. Correspondingly, after receiving the pre-monitoring failure information, the terminal can display the pre-monitoring failure information on a display interface.

Wherein, the pre-monitoring condition may include: the target video wall includes a plurality of display screens of the same type. Because the relationships between the resolutions and the sizes of different display screens are different, that is, the pixel pitches of different display screens are different, for example, the screen resolution of the LCD may be 1920 × 1080, the screen size may be 1920 × 1920, the screen size of the LED display screen is the screen resolution, and when the screen resolution of the LED display screen is 1920 × 1080, the size of the LED display screen is 1920 × 1080, so when the target television wall includes different display screens, the coordinates of each pixel point in the video image displayed in each first window on the television wall cannot be determined in the same rectangular coordinate system, that is, the display position of the video image relative to the corresponding first window cannot be determined.

Step 404, the main control server determines k video code streams in the n video code streams based on the identification information of the k input source devices.

The k video code streams are used for being displayed in m first windows of a target television wall, the m first windows are in one-to-one correspondence with the m second windows, namely, the m first windows on a display interface of the terminal and the m first windows on the target television wall have an equal scaling relationship, a plurality of block images can be displayed on the display interface of the terminal to simulate the specification and layout of a plurality of display screens on the target television wall, and the positions of the m second windows on the plurality of block images are the same as the positions of the m first windows on the plurality of display screens on the target television wall.

Step 405, the master control server sends k video code streams to the terminal.

Optionally, the pre-monitoring request may further include window information of m first windows, and the method for the master control server to send k video streams to the terminal, as shown in fig. 5A, may include:

step 4051, based on the window information, determining position information, where the position information is used to indicate display positions of the k first video images corresponding to the k video streams relative to the m first windows when the k first video images are respectively set in the corresponding first windows.

Optionally, the window information may include position information and size information of the m first windows and a correspondence between the m first windows and the k input source devices, and accordingly, the method for determining the position information based on the window information may include:

respectively decoding k video code streams provided by k input source devices to obtain data of k first video images; and according to the corresponding relation and the position information and the size information of the m first windows, respectively setting the k first video images in the corresponding first windows to determine the position information.

For example, a rectangular plane coordinate system shown in fig. 5B is established with the width direction of the target tv wall as the x axis and the height direction of the target tv wall as the y axis, and referring to fig. 5B, it is assumed that the target tv wall includes 2 × 2 display screens M, three first windows are displayed on the target tv wall, and the coordinates of the central points of the three first windows are (x) respectively₁，y₁)，(x₂，y₂) And (x)₃，y₃) The corresponding dimension is L₁*H₁，L₂*H₂And L₃*H₃Let a certain input source device correspond to a center point with coordinates (x)₂，y₂) After receiving the video code stream sent by the certain input source device, the main control server sets a target first video image obtained by decoding the video code stream at a central point with coordinates (x)₂，y₂) To determine position information of the target first video image, which may include coordinates of a center point of the target first video image and coordinates of each corner.

Fig. 5B is a method for establishing an optional coordinate system according to an embodiment of the present invention, where in fig. 5B, a vertex of a lower left corner of a target television wall is used as an origin, and in practical applications, a planar rectangular coordinate system may also be established by using the vertex of the upper left corner of the target television wall as the origin, which is not limited in the embodiment of the present invention.

Step 4052, the k video code streams and the position information are combined to obtain the target video code stream.

Optionally, the data and the position information of the k first video images may be combined to obtain the target video code stream.

Further, the window information may further include data of a background image of the target television wall, and then the combining is performed on the k video code streams and the position information to obtain the target video code stream, which may include: and combining the k video code streams, the position information and the data of the background image to obtain the target video code stream.

It should be noted that the background image of the target television wall may be configured by the terminal, and after determining the background image of the target television wall, the terminal may send data of the background image to the main control server, and the main control server stores the data of the background image.

Step 4053, sending the target video code stream to the terminal.

And step 406, the terminal acquires the position information of the video images corresponding to the k video code streams.

Optionally, the terminal may determine the location information based on the window information of the m first windows; or, after the terminal receives the target video code stream sent by the main control server, the terminal can decode the target video code stream to obtain the position information.

And 407, the terminal correspondingly displays video images corresponding to the k video code streams in m second windows on a display interface of the terminal based on the position information.

Optionally, the terminal may store a mapping relationship between m first windows and m second windows, where the mapping relationship may include a scaling relationship between the m first windows and the m second windows, and with reference to step 405, the terminal may receive a target video code stream sent by the master control server, and correspondingly, the method for correspondingly displaying video images corresponding to k video code streams in the m second windows on the display interface of the terminal, as shown in fig. 5C, may include:

step 4071, decoding the target video code stream to obtain k first video images and position information.

Optionally, the target video code stream may be obtained by the main control server combining data and position information of the k first video images, and the terminal decodes the target video code stream to obtain the k first video images and position information.

It should be noted that, the main control server sends the target video code stream to the terminal, and the terminal can directly obtain the k first video images and the position information based on the target video code stream, and does not need to perform other operations on the terminal, so that the operation burden of the terminal can be reduced, and the requirement on the processing performance of the terminal is lowered.

Step 4072, based on the position information and the mapping relationship, determining k second video images corresponding to the k first video images, and display positions of the k second video images relative to the m second windows.

Optionally, the width direction of a plurality of block images displayed by a terminal simulation target television wall is taken as an x axis, the height direction is taken as a y axis, a planar rectangular coordinate system is established on a display interface of the terminal corresponding to the target television wall, a measurement unit of the planar rectangular coordinate system on the terminal is in a proportional relation with a measurement unit of the planar rectangular coordinate system on the target television wall, the proportion is consistent with the scaling proportion of the m second windows and the m first windows, namely, the coordinate of the same pixel point in the coordinate system of the target television wall is the same as the coordinate in the coordinate system of the terminal.

Accordingly, the terminal may determine the position information of the k second video images with respect to the m second windows based on the position information of the k first video images.

Step 4073, correspondingly displaying the k second video images in the m second windows on the display interface based on the display positions of the k second video images relative to the m second windows.

Optionally, the method for correspondingly displaying k second video images in m second windows on the display interface includes:

performing translucency treatment on the m second windows; and displaying the k second video images on the display interface, and correspondingly overlapping and displaying the m second windows subjected to the translucency processing on the upper layers of the k second video images.

It should be noted that, since the m second windows on the terminal are used to adjust the m first windows on the target television wall, in order to perform window operations on the m second windows, the m second windows are usually displayed on the uppermost layer of the display interface of the terminal, and further, the second windows may be subjected to a translucency process in the process of pre-monitoring display, so as to prevent the second windows from blocking the second video images on the lower layer.

Optionally, the window information may further include data of a background image of the target television wall, and correspondingly, the target video code stream may be obtained by the main control server by combining the k video code streams, the position information, and the data of the background image, and then the k second video images are displayed on the display interface, and the m second windows after the translucency processing are correspondingly displayed in an overlapping manner on the upper layer of the k second video images, and may include:

and sequentially displaying the background image, the k second video images and the m second windows subjected to the translucency treatment in a display interface in an overlapping manner from the lower layer to the upper layer. That is, the layers on the display interface of the terminal sequentially include a background image layer, a second video image layer, and a second window layer from bottom to top.

It should be noted that, by adding the background image of the target television wall on the display interface of the terminal, the picture displayed on the terminal can be completely consistent with the picture displayed on the television wall, so as to achieve a better pre-monitoring display effect.

Step 408, after detecting that a preset window operation is performed on the second window on the display interface, the terminal determines new window information of the m second windows based on the mapping relationship between the m first windows and the m second windows stored in the terminal.

Optionally, the preset window operation may include: at least one of opening a window, closing a window, moving a window, and splitting a window. In practical applications, the window operation may also include other operations, and the embodiment of the present invention does not limit the type of the window operation.

The method comprises the steps that a window is opened, namely a second window is additionally displayed on a display interface of a terminal, and the newly added second window can be used for displaying video images corresponding to video streams provided by input source equipment except k input source equipment in n input source equipment; the closing of the window means reducing a second window displayed on a display interface of the terminal; moving a window refers to changing the position information and/or size information of the window; the window division means that the number of windows of the second window is changed, and a plurality of windows obtained after division can be used for jointly displaying video images corresponding to video code streams provided by the originally corresponding input source equipment.

And 409, generating a window information change instruction by the terminal, wherein the window information change instruction carries new window information.

The window information change instruction is used for indicating the master control server to update the local window information.

And step 410, the terminal sends a window information change instruction to the master control server.

Step 411, the main control server updates the local window information based on the new window information.

Further, the main control server can adjust the parameter information of the encoding controller and the decoding controller based on the new window information so as to adjust the first window displayed on the target television wall and the first video image displayed in the first window.

Step 412, after the terminal completes the configuration of the target television wall, the terminal sends a pre-monitoring ending request to the master control server.

And the pre-monitoring ending request is used for indicating the main control server to stop sending the video code stream to the terminal.

Optionally, after the terminal sends the pre-monitoring end request to the master control server, the pre-monitoring picture may be closed, that is, the second video image is not displayed on the display interface, and the second window on the display interface is materialized.

And step 413, the master control server stops sending the video code stream to the terminal.

The master control server stops sending the video code stream to the terminal, that is, the master control server stops receiving the video code stream provided by the input source device corresponding to the target television wall and stops combining the video code stream.

It should be noted that, the sequence of the steps of the pre-monitoring display method provided in the embodiment of the present invention may be appropriately adjusted, and the steps may also be increased or decreased according to the circumstances, and any method that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the protection scope of the present invention, and therefore, the detailed description is omitted.
