The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to solve the problem of the prior art, the embodiment of the invention provides a method and a system for mounting a terminal window on a wall from the perspective of a terminal and a television wall.
First, a method for putting a window on a wall of a terminal provided by the embodiment of the present invention is described below from a terminal perspective.
It should be noted that the terminal communicates with the video wall, where the terminal may be: the number of display units of the television wall is not limited herein, and the devices such as the smart television, the notebook computer, the tablet computer, and the smart phone which have the requirements for being mounted on the wall through the window exist. In addition, the communication mode between the terminal and the television wall may be network communication, and specifically, the network communication may be wireless network communication or wired network communication, which is reasonable.
It can be understood that, it is reasonable that the functional software for implementing the method for loading the window of the terminal onto the wall provided by the embodiment of the present invention from the terminal perspective may be a special client software provided in the terminal, or may be a functional plug-in provided in an existing client software provided in the terminal.
As shown in fig. 1, a method for mounting a terminal window on a wall provided from a terminal perspective in an embodiment of the present invention may include the following steps:
s101: determining a target window to be put on a wall;
an application program window (e.g., a word window, a browser window) selected by a mouse pointer may be determined as a target window to be put on a wall, or a window satisfying a preset condition may be determined as a target window to be put on a wall by functional software, for example: the preset conditions may be: the size of the window is 10 cm long and 10 cm wide, but the preset condition is not limited to this, and can be determined according to specific requirements. In addition, the method is not limited to the above two methods for determining the target window to be mounted on the wall.
It is understood that all functional software capable of determining a window is applicable, and the functional software is not described in detail herein.
It should be emphasized that the determined window to be placed on the wall may be a window corresponding to an application program, may also be a desktop window for a computer desktop, and may also be a window corresponding to a fixed area in a terminal display interface defined by a user. When a predetermined trigger condition is met, the step of determining a target window to be put on the wall may be triggered and executed, and specifically, the predetermined trigger condition may be: it is reasonable to receive a wall-up command from the user, or to reach a predetermined time, etc.
S102: obtaining a real-time code stream containing the window content of the target window;
after a target window to be mounted on a wall is determined, a real-time code stream corresponding to the window content of the target window is obtained. Specifically, the real-time code stream of the window content of the target window may be obtained through video recording software such as a screen video recorder, but is not limited thereto. Specifically, the specific implementation manner of obtaining the real-time code stream including the window content of the target window through the video recording software may be: and the video software carries out screenshot processing on the target window according to a preset screenshot frequency and compresses the acquired screenshot according to a standard video format to obtain a real-time code stream corresponding to the window content of the target window.
For example, screenshot processing may be performed on the window content of the target window by using a screen recording expert to obtain a screenshot, where the screenshot frequency may be preset to 10 seconds; and compressing the acquired screenshot according to a standard video format to obtain a real-time code stream corresponding to the window content of the target window. In addition, after the real-time code stream is obtained, the real-time code stream can be stored.
It is emphasized that the real-time code stream is composed of a plurality of video frames, each of which includes the complete window content of the target window, the complete window content includes: the window itself and the content displayed in the window.
S103: virtualizing the target window into a target monitoring point with preset monitoring parameters, so that the television wall acquires the real-time code stream from the target monitoring point by using the preset monitoring parameters, and displaying the window content of the target window on the wall based on the acquired real-time code stream, wherein the preset monitoring parameters can uniquely determine the target monitoring point.
And the target window is virtualized into a target monitoring point with the preset monitoring parameters by configuring the preset monitoring parameters for the target window. The target window can be uniquely determined through the preset monitoring parameters, and the address corresponding to the target monitoring point can be found according to the preset monitoring parameters, namely the real-time code stream corresponding to the window content of the target window can be found, and the real-time code stream is extracted from the address. Specifically, what is called virtualizing the target window into target monitoring points having predetermined monitoring parameters is: and identifying the target window through a target monitoring point with a preset monitoring parameter, wherein the stream extraction from the target monitoring point is to extract the real-time code stream corresponding to the target window.
It is emphasized that the terminal may send the predetermined monitoring parameter to the television wall, so that the television wall can know the predetermined monitoring parameter; certainly, the predetermined monitoring parameter may be information predetermined by the television wall and the terminal, and at this time, the terminal may not need to send the predetermined monitoring parameter to the television wall, and the television wall can obtain the predetermined monitoring parameter; in addition, the user can check the preset monitoring parameters on the terminal by himself, so that the preset monitoring parameters are output in the human-computer interaction interface of the television wall, and the method is reasonable.
In the embodiment of the invention, the terminal can determine the target window to be mounted on the wall and obtain the real-time code stream of the target window; presetting monitoring parameters for the target window to find the target monitoring point through the preset monitoring parameters, namely realizing the virtualization of the target window into the target monitoring point; correspondingly, the television wall end can uniquely determine the target monitoring point according to the monitoring parameter, and acquire the real-time code stream of the target window corresponding to the target monitoring point, so that the target window is projected to a display of the television wall, the problem that more display cards are needed when multiple windows on a terminal need to be projected to the television wall is solved, and the cost of mounting the windows on the wall is reduced.
In addition, the preset monitoring parameters are obtained at the television wall side, and when the real-time code stream is extracted from the target monitoring point by using the preset monitoring parameters, the real-time code stream can be directly transmitted by adopting a wired network or a wireless network. When the real-time code stream is transmitted by adopting a wired network, the VGA cable does not need to be connected between the terminals and the television wall when windows on a plurality of terminals need to be projected to the television wall, and the cost of the windows on the television wall is further reduced.
When the real-time code stream is transmitted through a wireless radio frequency signal (namely, a wireless network), the transmission of the real-time code stream can be realized without connecting the terminal and the television wall for many times, and the complexity of the connection is reduced.
Optionally, in an implementation manner, the obtaining a real-time code stream including the window content of the target window may include: screenshot processing is carried out on the window content of the target window according to a preset frequency, and a screenshot is obtained; and compressing the screenshot into a real-time code stream.
It can be understood that, in this implementation manner, screenshot processing may be performed on window content corresponding to the target window according to a preset frequency, and an image (i.e., screenshot) obtained after the screenshot processing is compressed into a real-time code stream. The preset frequency may be 1 second, 2 seconds, or 10 seconds, and may be specifically set by a person skilled in the art according to specific requirements, which is not limited herein. In addition, the compression of the pictures into real-time code streams can adopt the prior art, and will not be detailed here.
It should be emphasized that the window content refers to the entire interface content of the corresponding target window.
Optionally, before performing screenshot processing on the window content of the target window according to the preset frequency, the method may further include:
judging whether the target window is in a maximized window state, if so, executing the step of performing screenshot processing on the window content of the target window according to a preset frequency;
if not, the window of the target window is maximized, and after the target window is maximized, the step of performing screenshot processing on the window content of the target window according to the preset frequency is executed.
It can be understood that, in this implementation manner, before the screenshot processing is performed on the window content of the target window according to the preset frequency, the target window is preprocessed, where the preprocessing manner includes: judging the window state of the target window, namely judging whether the target window is in a maximized state, if so, continuing to perform screenshot operation on the window content; otherwise, the target window is adjusted to be the maximized window within the time of the screenshot operation, so that the problem that the resolution of the intercepted picture is low due to the fact that the number of pixels is small when the range of the target window is small is solved, and the problem that the picture projected to a television wall is not clear is solved. The window state of the target window may be obtained by obtaining a window handle of the target window, but is not limited to this.
It should be emphasized that, when screenshot is performed on the window content of the target window, shielding of the target window by a non-target window should be avoided, that is, when a plurality of windows on the same terminal need to be simultaneously subjected to wall-mount operation, the plurality of windows should be in a non-shielded state, so as to smoothly capture the window content of the plurality of windows.
In addition, the target window is maximized to the prior art and is not described in detail herein.
Optionally, before performing screenshot processing on the window content of the target window according to the preset frequency, the method may further include:
and judging whether a mouse pointer is detected in the target window, if not, executing the step of carrying out screenshot processing on the window content of the target window according to the preset frequency.
It can be understood that, in this implementation manner, in order to obtain a relatively pure screenshot, when a mouse pointer is detected to exist in a target window, screenshot may not be performed on the window content of the target window; when the mouse is detected not to exist in the target window, screenshot is conducted on the window content of the target window according to the preset frequency, so that the same mouse action cannot occur in a television wall when a user executes the mouse action on the target window of the terminal, and the watching experience of the user is improved. The prior art is to detect whether a mouse pointer exists in a target window, and details thereof are not described herein.
Optionally, after virtualizing the target window as a target monitoring point having predetermined monitoring parameters, the method may further include:
and sending the preset monitoring parameters to a monitoring parameter display platform for a user to edit or view the preset monitoring parameters of the target monitoring point.
It can be understood that, in this implementation manner, after the target window is virtualized as a target monitoring point, the predetermined monitoring parameters of the target monitoring point are sent to the monitoring parameter presentation platform. The monitoring parameter display platform can provide an interface for a user to view and edit the preset monitoring parameters. The monitoring display parameter platform can be arranged on any equipment, and the equipment is not limited herein.
Optionally, the predetermined monitoring parameters include a network protocol IP address, a port number, and a channel number.
It can be understood that, in this implementation manner, the predetermined monitoring parameters may include an IP address, a port number, and a channel number, that is, an address corresponding to a terminal where the target monitoring point is located may be found through the IP address, the target monitoring point in the terminal may be further found through the port number, and the real-time code stream of the target monitoring point may be transmitted according to a channel corresponding to the channel number. When there are multiple target windows to be mounted on the wall in one terminal, the port values of multiple target monitoring points corresponding to the multiple target windows should be different.
It should be noted that the port corresponding to one IP address may be numbered by 16 bits (of course, other bits are also possible), and there may be 65536 ports at most. In order to distinguish the ports, each port is numbered, and the ports are marked by the port numbers. And can distinguish different network services by means of IP address + port number, which is the prior art and will not be described in detail herein. In addition, the channel number refers to a number corresponding to a data path for transmitting information, and one port may include a plurality of data paths.
The following describes a method for putting a terminal window on a wall according to an embodiment of the present invention from a perspective of a television wall.
It should be noted that the video wall is in communication with a terminal, where the terminal may be: the number of display units of the television wall is not limited herein, and the devices such as the smart television, the notebook computer, the tablet computer, and the smart phone which have the requirements for being mounted on the wall through the window exist. In addition, the communication mode between the terminal and the television wall may be network communication, and specifically, the network communication may be wireless network communication or wired network communication, which is reasonable.
It can be understood that, it is reasonable that the functional software for implementing the method for mounting a terminal window on a wall from the perspective of a television wall according to the embodiment of the present invention may be a special client software provided in the television wall, or a functional plug-in existing client software provided in the television wall.
As shown in fig. 2, a method for mounting a terminal window on a wall from a television wall perspective according to an embodiment of the present invention may include the following steps:
s201: obtaining preset monitoring parameters of a target monitoring point to be mounted on a wall, wherein the target monitoring point is a monitoring point obtained by virtualizing a target window to be mounted on the wall through the terminal;
the method comprises the following steps that a user can directly check preset monitoring parameters of a target monitoring point at a terminal and input the preset monitoring parameters into a man-machine interaction interface given by a television wall, so that the television wall can perform stream taking operation on the target monitoring point; the preset monitoring parameters of the target monitoring point can also be sent to the television wall through the terminal, and the television wall carries out stream taking operation on the target monitoring point according to the preset monitoring parameters; certainly, the predetermined monitoring parameter may be a monitoring parameter agreed in advance by the terminal and the television wall, and at this time, the television wall can obtain the predetermined monitoring parameter without inputting by the user and transmitting the predetermined monitoring parameter by the terminal, which is also reasonable.
S202: extracting a real-time code stream from the target monitoring point based on the preset monitoring parameter, wherein the real-time code stream is a code stream which is obtained by the terminal and contains the window content of the target window;
the television wall can actively obtain the preset monitoring parameters and also can passively receive the preset monitoring parameters, and can extract real-time code streams from target monitoring points according to the preset monitoring parameters by using stream-taking software in the television wall. Specifically, a wall-up rule of the target window may be configured through configuration software built in the television wall, where the wall-up rule refers to a decoder to which the real-time code stream corresponding to the target window is to flow, so as to output a display of the television wall to which the decoded real-time code stream of the decoder flows. And after the wall-climbing rule is configured, notifying the configuration information to a corresponding decoder so that the decoder can call stream-taking software to extract a real-time code stream from a target window pointed by the configuration information.
The terminal may obtain the real-time code stream of the window content of the target window through software such as a screen recording expert, which is not limited to this. And the real-time code stream is composed of a plurality of video frames, each video frame comprises the complete window content of the target window, and the complete window content comprises: the window itself and the content displayed in the window.
In addition, in the terminal, the target window may be selected by a mouse pointer in the terminal, for example, an application program window (e.g., a word window, a browser window) in the terminal selected by the mouse pointer is used as the target window, or a window satisfying a preset condition may be determined as a target window to be put on a wall by using function software in the terminal, for example: the preset conditions may be: the size of the window is 10 cm long and 10 cm wide, but the preset condition is not limited to this, and can be determined according to specific requirements. In addition, the method is not limited to the above two methods for determining the target window to be mounted on the wall.
It is understood that all functional software capable of determining a window is applicable, and the functional software is not described in detail herein.
It should be emphasized that the window to be placed on the wall determined in the terminal may be a window corresponding to an application program, may also be a desktop window for a computer desktop, and may also be a window corresponding to a fixed area in a terminal display interface defined by a user. When a predetermined trigger condition is met, the terminal may trigger and execute the step of determining the target window to be put on the wall, and specifically, the predetermined trigger condition may be: it is reasonable to receive a wall-up command from the user, or to reach a predetermined time, etc.
In addition, the terminal can configure the preset monitoring parameters for the target window to realize that the target window is virtualized into the target monitoring point with the preset monitoring parameters. The target window can be uniquely determined through the preset monitoring parameters, the television wall can find the address corresponding to the target monitoring point according to the preset monitoring parameters, namely the real-time code stream corresponding to the window content of the target window can be found, and the real-time code stream is extracted from the address. Specifically, what is called virtualizing the target window into target monitoring points having predetermined monitoring parameters is: and identifying the target window through a target monitoring point with a preset monitoring parameter, wherein the stream extraction from the target monitoring point is to extract the real-time code stream corresponding to the target window.
It can be understood that, when the predetermined monitoring parameter is obtained at the television wall side, the predetermined monitoring parameter can be used to extract the real-time code stream from the target monitoring point, and after the extracted implementation code stream is processed, the window content of the target window is displayed on the wall. The problem that a display card needs to be added when a plurality of windows on one terminal need to be subjected to wall mounting operation is avoided, and the wall mounting cost of the terminal windows is reduced.
In addition, the preset monitoring parameters are obtained at the television wall side, and when the real-time code stream is extracted from the target monitoring point by using the preset monitoring parameters, the real-time code stream can be directly transmitted by adopting a wired network or a wireless network. When the real-time code stream is transmitted by adopting a wired network, the VGA cable does not need to be connected between the terminals and the television wall when windows on a plurality of terminals need to be projected to the television wall, and the cost of the windows on the television wall is further reduced.
When the real-time code stream is transmitted through a wireless radio frequency signal (namely, a wireless network), the transmission of the real-time code stream can be realized without connecting the terminal and the television wall for many times, and the complexity of the connection is reduced.
S203: and displaying the window content of the target window on the wall based on the obtained real-time code stream.

The following describes, with reference to fig. 6, an example of a workflow of the terminal window wall-up system according to the embodiment of the present invention.
For example, the terminal window wall-mounting system includes a television wall, a monitoring parameter display platform and 3 computers, wherein the 3 computers are respectively a computer 1, a computer 2 and a computer 3, and each computer includes 2 target windows (window 1 and window 2) to be wall-mounted.
In the working process, after the computer 1, the computer 2 and the computer 3 determine the target window 1 and the window 2 to be put on the wall, screenshot processing is respectively carried out on the window 1 and the window 2 by utilizing screen recording expert software, and the obtained screenshot is compressed according to a standard video format to obtain real-time code streams corresponding to the window contents of the window 1 and the window 2.
The virtualization units built in the computers 1, 2 and 3 respectively virtualize the corresponding windows 1 and 2 into target monitoring points with preset monitoring parameters. For example, the computer 1 virtualizes a window 1 to be placed on a wall as a target monitoring point 1, where the target monitoring point has predetermined monitoring parameters: the network protocol IP address is 198.1.1.1, port number is 20, and channel number is 0.
And then, each computer sends the preset monitoring parameters of the target window to be mounted on the wall to the television wall. And the television wall acquires the real-time code stream from the target monitoring point according to the preset monitoring parameters. For example, after obtaining the preset monitoring parameter of the window 1 on the computer 1, the video wall may obtain the real-time code stream corresponding to the window 1 according to the network protocol IP address of 198.1.1.1, the port number of 20, and the channel number of 0.
Specifically, the television wall configures the wall-loading rule of the target window through the built-in configuration software, that is, configures a decoder to which the real-time code stream corresponding to the target window flows and a display of the television wall that outputs the flow direction of the decoded real-time code stream of the decoder. And after the configuration information corresponding to the on-wall rule is sent to a corresponding decoder arranged in the television wall, the decoder extracts a real-time code stream from a target window pointed by the configuration information by calling stream-taking software arranged in the television wall, and then displays the real-time code stream on a corresponding display.
After virtualizing a target window to be put on the wall into a target monitoring point with preset monitoring parameters, each computer can store the preset monitoring parameters to a monitoring parameter display platform, so that a user can edit or view the preset monitoring parameters of the target monitoring point in each computer on the monitoring parameter display platform.
