After determining the target source, the control device can, in response to the user's reverse control operation on the target source, establish a network connection between the control device and the target source device. Since the layered image is generated by the target source and displayed on the operation display interface, and a network connection exists between the control device and the target source device, editing commands based on the layered image can be sent to the target source device.

[0042] As used in this application specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection."

[0043] Furthermore, in the description of this application and the appended claims, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0045] In existing technologies, fixed display screens are typically installed in areas isolated from video processing equipment, and their locations are relatively fixed. While the control equipment for video processing can display the processed input source on the fixed display screen, limitations imposed by the environment and network restrict its direct control over the input source. For example, in a fixed conference system, the control equipment for the conference screen and video processing equipment can be used in the conference room, while the input source and video processing equipment themselves need to be located in a server room. During a meeting, it's difficult to control the input source in the server room from the meeting location; someone needs to be present to operate it when needed, causing significant inconvenience and a poor user experience.

[0046] To address the aforementioned issues, this application provides a remote control method for a display screen input source, enabling remote control of the display screen input source device from different locations. For example, it allows operation of the input source device located in the computer room from the meeting venue during a conference.

[0047] By way of example and not limitation, the video processing device in the remote control method for the display input source provided in the embodiments of this application may refer to a KVM (Keyboard, Video, Mouse) switcher, a VGA (Video Graphics Array) switcher, an AV (Audio and Video) switcher, a High Definition Multimedia Interface (HDMI) switcher, a Digital Visual Interface (DVI) switcher, etc.

[0048] As an example and not a limitation, the control device for video processing equipment can refer to various devices such as personal computers (PCs), tablets, personal digital assistants (PDAs), and mobile internet devices (MIDs) capable of operating remote control methods from display input sources.

[0049] By way of example and not limitation, the display screen in the embodiments of this application may be one of the following: LCD display screen, LED display screen, OLED display screen and QLED display screen.

[0050] Taking LED displays as an example, these LED displays can be ordinary LED displays, or they can be microLED, miniLED, or new types of LEDs in the future.

[0051] Furthermore, in some embodiments, the display screen can be packaged using one of the following methods: for example, SMD, COB, COG, or future novel packaging methods. This application does not specifically limit the size of the display screen; it can be a large-sized display screen, such as those used in shopping malls or concerts. The display screen can be composed of many splicing units. These splicing units are sometimes referred to as light boxes (such as LED light boxes). For a display screen using a light box as the basic unit, the display screen mentioned in this application can refer to a display screen corresponding to a single light box, or it can refer to a display screen composed of multiple light boxes spliced ​​together. It can also be a smaller-sized display screen, such as a light box or light panel. With future developments in displays, smaller-sized displays may contain a larger number of pixels, and the methods provided in this application are also applicable.

[0052] It should be understood that the sequence number of each step in this embodiment does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of this application embodiment.

[0053] To illustrate the technical solution of this application, specific embodiments are described below.

[0054] See Figure 1 This diagram illustrates the structure of a remote control system for a display input source provided in Embodiment 1 of this application. Figure 1 As shown, the remote control system includes video processing equipment, control equipment for the video processing equipment, a display screen, and multiple input source devices. Figure 1The input source device 1, input source device 2, input source device 3 and input source device 4 in the example are only examples, and the specific number of input source devices is not limited in this application.

[0055] In the field of fixed display screens, video processing equipment can process (e.g., edit, splice, integrate) layers of images generated by multiple input source devices, and then output the processed layers to the display screen for display. However, since the usage locations of video processing equipment and display screens are often geographically separated, a third party is needed to control the video processing equipment. This third party can visually demonstrate the processing of multiple layers of images and the process of displaying the processed layers. This third party can be a control device for the video processing equipment, such as a computer or tablet computer with control software. This device controls the video processing equipment, visualizes its operation, and facilitates operation. However, current control devices cannot control the input source devices connected to the video processing equipment, still requiring manual operation.

[0056] To enable remote control of input source devices, the control device can first add video processing devices located on the same network segment as the control device by responding to user add operations, thereby enabling control of the video processing devices. Since the video processing devices and input source devices are often connected by physical means, such as data cables, and have a certain physical connection relationship, the input source list of the video processing devices can be obtained.

[0057] Secondly, the control device can respond to the user's target source configuration operation and determine the target source from the input source list, where the target source is the target source selected by the user from the input source list.

[0058] Finally, in response to the user's reverse control operation on the target source, a reverse control command is sent to the target source device to establish a handshake connection, i.e., to establish a network connection between the control device and the target source device. Then, the target source device can capture the current display screen and send it to the control device to be displayed as a layer screen generated by the target source in the operation display interface. After the layer screen is displayed in the operation display interface, the user can edit the layer screen. In response to the editing operation, the control device can send an editing command based on the layer screen to the target source device through the network connection between the control device and the target source device. After receiving the editing command, the target source device can execute the editing command and send the display screen generated after the editing command to the control device to display the display screen as a layer screen in the operation display interface, thereby realizing the remote control of the target source device by the control device.

[0059] This application establishes a network connection between the control device and the target source device through video processing equipment. By establishing this network connection and using the methods of sending commands and receiving images, it solves the problem that current control devices cannot control input source devices and still require manual operation, resulting in inconvenience and a poor user experience.

[0060] For example, the control software can be started on the control device first. After the control software starts, it searches for video processing devices on the same network segment as the control device, or the IP address of a video processing device on the same network segment can be directly entered. Responding to the user's click on the "Add Control" button on the interface, video processing devices on the same network segment as the control device are added. Since the input and output interfaces of the video processing devices are connected to the input source devices and the display screen respectively, the control device can obtain the list of input sources for the video processing devices. Next, in response to the user's target source configuration operation, input source 1 in the input source list is designated as the target source, where input source 1 corresponds to input source device 1. After configuring the target source, the layered screen generated by the target source can be displayed in the screen topology diagram. Based on this layered screen, the user can perform reverse control operations on the target source to establish a network connection between the control device and the target source device. The screen topology diagram is generated based on the configuration of the output interfaces of the video processing devices and is also displayed in the operation display interface of the control device. After establishing a network connection, the user can edit the input source 1 based on the layer screen. For example, the layer screen is the desktop display screen of the input source device 1, which includes a file A. The user can then edit the layer screen, such as clicking on the file A in the layer screen and opening it. The control device can send the open operation command to the input source device 1. Upon receiving the open operation command for file A, the input source device 1 can execute the operation command, open file A, and send the display screen generated after opening file A to the control device. This display screen is then used as the layer screen generated by the input source 1 and displayed in the operation display interface, thus realizing the remote control of the target source device by the control device.

[0061] It should be understood that, in response to the user's selection of the target source, any input source device may be used as the target source device, and the input source device selected as the target source is controlled in the same way as the above-mentioned controlled process.

[0062] It should also be understood that the target source device needs to have the controlled operating system and a corresponding version of the remote service program installed. The controlled operating system is used to run the remote service program. Here, as an example and not a limitation, the operating system can be Android, iOS, Windows, etc., and the installed remote service program should be the version corresponding to the operating system. The remote service program can be used to capture the screen of the controlled device and respond to the control device's reverse control and editing commands. In one optional approach, it can also provide an entry point for enabling annotation (e.g., displaying a shortcut to the annotation program on the target source device's desktop), facilitating the execution of annotation program start commands sent by the control device.

[0063] Among them, capturing the screen of the controlled terminal can be done by calling the desktop image data stream through the D3Dhook interface or by obtaining screenshots.

[0064] In this embodiment, the control device can establish a network connection with multiple input source devices through a video processing device. Then, through this network connection, it sends editing instructions based on the corresponding layer of the image to the selected input source device (i.e., the target source device). The input source device responds to the editing instructions, performing corresponding editing operations, and sends the resulting image to the control device, thus enabling remote control of the selected input source device. In fixed scenarios, such as conferences, this solves the problem of difficulty in controlling input source devices located in a server room at the conference venue, preventing operational inconvenience.

[0065] Reference Figure 2 This illustration shows a flowchart of a remote control method for a display input source provided in Embodiment 2 of this application. Applied to... Figure 1 The system includes control equipment for controlling the video processing equipment, and the control equipment includes an operation display interface, such as... Figure 2 As shown, the remote control method may include the following steps:

[0066] Step 201: In response to the user's add operation, add a video processing device that is in the same network segment as the control device.

[0067] In this embodiment, the user's "add" operation can refer to the user's click operation on the operation display interface to add controls. It should be noted that video processing devices can be added manually or through automatic search.

[0068] The manual addition method can be as follows: the user clicks the manual addition control button on the operation display interface to generate an addition command. In response to the user's addition command, a pop-up window is set up to input the IP address. The user can enter the IP address of the video processing device that is in the same network segment as the control device, and then add the video processing device corresponding to the IP address to the control software of the control device to establish a connection between the control device and the video processing device. This connection is a TCP / IP network connection.

[0069] The automatic search method can be as follows: the user inputs the network segment where the control device is located, clicks the automatic search control button on the operation display interface to obtain a list of video processing devices, and the user can click the add button of the corresponding video processing device to generate an add command. In response to the user's add command, the video processing device can be added to the control software of the control device to establish a connection relationship between the control device and the video processing device. This connection relationship is a TCP / IP network connection.

[0070] Step 202: Obtain the list of input sources for the video processing device.

[0071] In this embodiment, obtaining the input source list of the video processing device is predicated on the completion of a physical connection between the video processing device and the input source devices. This physical connection can include the physical connection between the input interface of the video processing device and the output interface of the input source devices. Therefore, once the physical connection between the video processing device and the input source devices is established, the input source list of the video processing device can be obtained directly.

[0072] In one possible implementation, after obtaining the list of input sources for the video processing device, the list of input sources can be displayed in the operation display interface to facilitate the user's configuration of the target source.

[0073] Step 203: In response to the user's target source configuration operation, determine the target source from the input source list.

[0074] In this embodiment, the user's target source configuration operation can refer to the user's drag operation on the control corresponding to any input source in the input source list on the operation display interface. The function of this drag operation corresponds to configuring the target source. Determining the target source from the input source list can refer to displaying the layer image generated by the target source on the operation display interface.

[0075] In one possible implementation, the remote control method also includes:

[0076] Acquire the first connection relationship between multiple output interfaces of the video processing device and at least one display screen;

[0077] Based on the first connection relationship, configure the display position and / or display size of multiple output interfaces on the operation display interface, generate a screen display topology map, and display it on the operation display interface;

[0078] In response to the user's target source configuration action, determine the target source from the input source list, including:

[0079] In response to the user's target source configuration operation, the target source is determined from the input source list, and the layer image generated by the target source is displayed in the screen display topology diagram, so that the target source establishes a display correspondence with multiple output interfaces.

[0080] In this embodiment, the layer image generated by the target source can be displayed in the operation display interface. When there is a first connection relationship between the multiple output interfaces of the video processing device and at least one display screen, the control device can configure the multiple output interfaces of the video processing device based on the first connection relationship and generate a screen display topology map in the operation display interface to show the display position and / or display size of the display screen connected to the multiple output interfaces. Since the layer image generated by the target source needs to be displayed on the screen after being processed by the control device, after determining the target source, the layer image generated by the target source can be displayed in the screen topology map, which is convenient for users to operate based on the layer image and is also convenient for display on the screen.

[0081] For example, assuming a video processing device has three output interfaces connected to three displays, the device can configure these interfaces based on their physical connections. The topology of these interfaces can then be displayed on the control device's interface, generating a screen display topology map. This topology map includes the positional and / or size relationships between the connected displays, allowing users to configure the actual resolution and splicing method of the connected displays. After generating the topology map, layers generated by the target source can be dragged directly into it, establishing a display correspondence between the target source and the multiple output interfaces. This means the layers can be displayed on the displays connected to the output interfaces that correspond to the target source.

[0082] Furthermore, after displaying the layer image generated by the target source on the screen as a topology map, the user can perform reverse control operations on the target source based on this layer image.

[0083] It should be understood that the physical connection relationship of multiple output interfaces in the screen display topology diagram generated by the operation display interface is consistent with the physical connection relationship of at least one display screen in the actual scene.

[0084] It should also be understood that the layered screen generated by the target source is displayed on the operation display interface, such as the screen topology diagram, to facilitate user operation based on the layered screen. Therefore, when controlling the target source device, this layered screen can be used as the control screen for controlling the target device. Since the screen displayed on the upper screen is also generated by the target source, the content of the screen displayed on the upper screen and the control screen can be the same, but the form is different. That is, the control screen is the screen being processed by the control device, while the screen displayed on the upper screen is the screen after the control device has processed it.

[0085] It is also important to understand that the content displayed on the reverse control screen and the screen displayed on the main screen can be different. For example, during the process of the control device processing the reverse control screen, it is possible to choose not to display the processing process on the main screen. In this case, the display screen can show the display screen of other input source devices, while the reverse control screen displays the layer screen generated by the target source.

[0086] In one possible implementation, the topological relationship between the displays connected to the output interface also includes the size relationship, which can be shown in the screen topology diagram as the resolution of each display.

[0087] In one possible implementation, the layer image generated by the target source is displayed in the screen display topology map, including:

[0088] In response to user adjustments to the layer view, determine the display position and / or display size of the layer view on the screen display topology map;

[0089] Display the layer images on the screen topology map based on their display position and / or display size.

[0090] In this embodiment, the user can adjust the display size and / or display position of the layer image (i.e., the display size of the layer image can be adjusted alone, the display position of the layer image can be adjusted alone, or both the display size and the display position of the layer image can be adjusted), generate an adjustment command, control the device to respond to the adjustment command, adjust the layer image, and display the adjusted layer image on the screen display topology map.

[0091] It should be understood that users can adjust the display size and position of the layer image by entering the display size and position coordinates in the operation display interface, or by directly performing operations such as zooming in, zooming out, and dragging the layer image.

[0092] Step 204: In response to the user's reverse control operation on the target source, establish a network connection between the control device and the target source device, and send layer-based editing instructions to the target source device through the network connection to remotely control the target source device.

[0093] In the embodiments of this application, reverse control can be a control means that sends control commands to a target source device to enable the target source device to control itself to execute commands.

[0094] In this embodiment of the application, the layer screen can refer to the screen generated by the target source device and displayed in the operation display interface.

[0095] In this context, responding to the user's reverse control operation on the target source can refer to the user configuring the reverse control on the target source, clicking the reverse control control on the configured layer screen, and generating a reverse control command.

[0096] In this embodiment of the application, in response to the user's reverse control operation on the target source, the generated reverse control command is sent to the target source device, and a handshake connection is established with the target source. After confirming that the target source has received the reverse control command, a network connection relationship between the control device and the target device can be established, for example, by configuring IP and port communication between the control device and the target source device.

[0097] In one possible implementation, establishing a network connection between the control device and the target source device includes:

[0098] Establish a network connection between the control device and the target source device based on the IP address and network data transceiver port number of the target source device.

[0099] For example, after sending a reverse control command to the target source device, the IP address and network data transceiver port number of the target source device can be obtained. The IP address and network data transceiver port number of the target source device can be input into the control software to establish an IP network connection between the control device and the target source device, and data can be transmitted through the network data transceiver port corresponding to the port number.

[0100] In this embodiment, the control device and the target source device have a network connection. The control device can send the editing instructions of the layer screen to the target source device through the configured network data transceiver port, so that the target source device can control itself to execute the editing instructions, that is, capture the current display screen of the target source device and send the current display screen of the target source device to the control device, so as to display the display screen as a layer screen in the operation display interface.

[0101] In one possible implementation, editing commands based on layered images are sent to the target source device via a network connection to remotely control the target source device, including:

[0102] Get the editing operations performed by the user on the layer image;

[0103] Encode the editing operations to generate editing instructions that represent them;

[0104] Editing instructions are sent to the target source device via a network connection to remotely control the target source device to perform editing operations according to the editing instructions.

[0105] Editing operations include at least keyboard and mouse operations and / or touch operations. It should be understood that if the control device is a computer device without touchscreen functionality, then editing operations can refer to keyboard and mouse operations, i.e., using a keyboard or mouse as the input device. If the control device is a computer device with touchscreen functionality, then editing operations can include keyboard and mouse operations and / or touch operations.

[0106] In this embodiment, the user performs keyboard and mouse operations and / or touch operations on the layer screen displayed on the operation display interface, and then encodes the editing operation, that is, performs encoding conversion according to the corresponding keyboard and mouse protocol or the corresponding touch protocol to generate editing instructions representing the editing operation. Then, the editing instructions are sent to the target source device through the configured network data transceiver port to remotely control the target source device to perform editing operations according to the editing instructions.

[0107] In one possible implementation, sending layer-based editing commands to the target source device via a network connection to remotely control the target source device also includes:

[0108] In response to the user's operation of starting the annotation program on the target source device through the layer screen, a starting command for the annotation program is sent to the target source device through the network connection;

[0109] After the annotation program starts, in response to the user's annotation operation on the layer screen, it sends annotation instructions to the target source device through the network connection, so that the target source device executes the annotation instructions and sends the generated annotation screen to the control device for layer display.

[0110] In this embodiment, the method by which the user generates the start command for the annotation program in the target source device via the control device can be as follows: the user clicks the shortcut of the annotation program in the layer screen of the start operation display interface, generates the annotation program start command, and sends the annotation program start command to the target source device to start the annotation program. Then, the user can perform annotation operations based on the layer screen of the operation display interface, generate annotation commands, send the annotation commands to the target source device to execute the annotation commands, and send the generated annotation screen to the control device for layer display.

[0111] In this embodiment, the control device, in response to a user's add command, adds a video processing device located on the same network segment as the control device. It then obtains the input source list of the video processing device and, in response to the user's target source configuration operation, determines the target source from the input source list. After determining the target source, the control device can, in response to the user's reverse control operation on the target source, establish a network connection between the control device and the target source device. Since the layered image is generated by the target source and displayed on the operation display interface, and a network connection exists between the control device and the target source device, editing commands based on the layered image can be sent to the target source device. This allows for remote control of the target source device to perform actions according to the editing commands, thus achieving remote control of the target source device. This solves the problem of difficulty in operating input source devices located in the computer room during a meeting, causing operational inconvenience.

[0112] See Figure 3 This illustration shows a flowchart of a remote control method for a display input source according to Embodiment 3 of this application. It is applied to the target source device, i.e. Figure 1 One of multiple input source devices in the system, such as Figure 3 As shown, the remote control method may include the following steps:

[0113] Step 301: Receive the reverse control command sent by the control device.

[0114] It should be noted that the remote control method in this application embodiment is applied to a target source device in the display input source, which is determined from multiple input source devices.

[0115] Among them, the reverse control command refers to the command sent by the control device in response to the user's reverse control operation on the target source. The target source device can receive the reverse control command through the network data transceiver port configured by the control device.

[0116] Step 302: Establish a network connection between the control device and the target source device, capture the display screen of the target source device, and send the display screen to the control device through the network connection so that the display screen can be displayed as a layer screen in the operation display interface.

[0117] In this embodiment, after receiving the reverse control command, the target source device first needs to establish a handshake connection with the control device, i.e., establish a TCP connection, so that both parties can receive each other's responses to received messages. During the handshake connection, the target source device executes the received reverse control command, captures the display screen of the target source device, and then transmits the display screen back to the control device via network backhaul, where it is displayed in the layer of the operation display interface.

[0118] It should be understood that data capture can be achieved by calling the desktop image data stream through the D3Dhook interface or by obtaining screenshots, and this application does not limit this.

[0119] Step 303: Receive editing instructions sent by the control device based on the layer screen, execute the editing instructions, and send the display screen generated after executing the editing instructions to the control device for display in the operation display interface.

[0120] In this embodiment of the application, the target source device can receive editing instructions sent by the control device through the network data transceiver port configured on the control device. The editing instructions are instructions to edit a certain control on the layer screen. Therefore, when the target source device executes the editing instructions, it performs an action on a certain control on the layer screen. After executing the instructions, it sends the generated display screen to the control device.

[0121] In one possible implementation, the editing instruction can refer to encoded information representing the user's editing operation, that is, encoded information based on the corresponding keyboard and mouse protocol and touch protocol. After receiving the encoded information, the target source device needs to decode the encoded information before it can obtain the corresponding editing instruction. That is, step 303 above can include:

[0122] Receive encoded information representing editing operations;

[0123] The encoded information is decoded using the corresponding decoding rules to determine and execute the editing instructions.

[0124] In this embodiment of the application, the target source device stores a parsing module corresponding to the keyboard and mouse protocol and touch protocol in the control device, which can be used to decode the encoded information using the corresponding decoding rules.

[0125] In one possible implementation, the target source device is equipped with a remote service program and an annotation program. The remote service program is used to respond to the control device's reverse control commands to enable the target source device to perform the control device's editing operations, and the annotation program is used to respond to the control device's annotation commands to enable the target source device to annotate the layer image generated by the target source.

[0126] In this embodiment, the target source device can receive the reverse control command from the control device, establish a handshake connection to inform the control device of its online status, and then, according to the remote service program installed on itself, capture the display screen according to the reverse control command, execute the operation corresponding to the editing command according to the editing command, and send the generated display screen after the operation to the control device, so as to realize the remote control of the target source device by the control device.
