When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
FIG. 1 is a schematic diagram of a remote mapping system. As shown in fig. 1, the remote image transmission system includes an image source device, an S-terminal device, an R-terminal device, and a display connected to the R-terminal device. The S-end device is connected with the image source device, and the R-end device is connected with the display.
It should be noted that, in the embodiment of the present disclosure, the S end is a transmitting end, and the R end is a receiving end.
In the scenario shown in fig. 1, the image source device comprises a display 11 and a display 12, the display 11 being the main display and the display 12 being the extended display; the display connected with the R terminal comprises a display 21, a display 22 and a display 23, wherein the display 11 corresponds to the display 21, and the display 12 corresponds to the display 22. According to the scheme in the prior art, if the desktop expansion effect of the display 23 needs to be achieved, a corresponding physical display needs to be added on the image source device, otherwise, the desktop expansion effect cannot be achieved at the R end. But adding a physical display not only incurs higher hardware costs but is not flexible enough.
In order to solve the problem, the disclosure proposes that when the R end and the S end are connected, the image source device generates one or more virtual displays meeting the remote link requirement on the image source device by using a virtual display driver development technology according to the number of remote linked screens, that is, the number of displays connected by the R end, so that the displays of the image source device are in one-to-one correspondence with the displays of the R end.
Fig. 2 is a flowchart of an image display method according to an embodiment of the present disclosure. As shown in fig. 2, the method includes:
Step 201, the receiving end detects and acquires the display information of the receiving end, and sends the display information of the receiving end to the source equipment;

The source equipment receives the display information of the receiving end, and determines the number N of virtual displays to be built according to the number of the displays of the receiving end and the number of the displays of the source equipment;
The source device establishes N virtual displays according to the number N of the virtual displays to be established and the virtual display drive which is installed in advance.
In this embodiment, the image source device determines, according to the number of displays connected to the receiving end and the number of displays of itself, that virtual displays need to be generated and determines the number of virtual displays that need to be established. For example, the image source device determines that 1 virtual display needs to be built again according to the number 3 of displays connected with the receiving end and the number 2 of displays of the image source device; next, the image source device generates a virtual display, i.e., a display 13 as shown in fig. 3, using a virtual display driver installed in advance, and the display 13 may be a main screen or an extension screen of the image source device.
The virtual display driver may be INDIRECT DISPLAY drivers. INDIRECT DISPLAY drives are pre-installed in the hardware devices of the image source device.

If a plurality of virtual displays need to be created, the above-described process may be repeatedly performed.
It will be appreciated that in some cases, the image source device may not configure a physical display, and when the receiving end establishes a connection with the transmitting end, the image source device establishes the same number of virtual displays according to the number of displays connected by the receiving end, and manages the created virtual displays. Thus, the image source device can be free from configuring a larger number of physical displays, thereby reducing the cost and improving the flexibility.

Step 205, the receiving end receives the desktop image, decodes the desktop image and displays the decoded desktop image on a corresponding display of the receiving end.
In this step, the R-terminal decodes the encoded data, restores the desktop image, and displays the restored desktop image on the corresponding display.
It should be noted that, a virtual display driver may be installed in the image source device in advance, where the virtual display driver may only be installed in a hardware device of the image source device, and when the image source device determines that the virtual display needs to be established, the virtual display is generated by running the virtual display driver, and the virtual display may be identified and managed by a windows operating system of the image source device. Then, the image source device outputs desktop images of windows to the virtual display to realize the expanded desktop effect of the image source device; the S end collects desktop images of the virtual display and desktop images of other physical displays of the image source equipment, codes the desktop images and sends the coded images to the R end, and the R end decodes and displays the coded data. Therefore, the problem that the R end cannot expand the desktop effect when the number of the S end displays is not matched with the number of the R end displays is solved.
