Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Referring to FIG. 1 , a method for displaying a wireless screen according to a first embodiment of the present invention is applied to a receiving terminal in a wireless screen transmission process, where the method includes:

S101. Receive operation data generated when a user moves a current coincidence point between a plurality of split screen display areas in a receiving terminal, where the operation data includes movement trajectory data of the current coincidence point in the receiving terminal, and the receiving The terminal simultaneously performs wireless transmission with the plurality of source terminals, and the image of each of the source ends is respectively displayed in the corresponding split screen display area of the receiving terminal;

In this embodiment, the receiving terminal is described by taking a conference tablet having a windows or an Android system as an example, and the source end is described by using a computer as an example. Specifically, there are four computers that perform wireless screen transmission with the conference tablet, wherein The conference tablet and each computer are equipped with corresponding screen transmission software. The computer and the conference tablet are in the same wireless network. Both can perform the conventional wireless screen in the prior art, and the screens of the four computers are divided into four screens. The wireless screen is displayed in the conference tablet. The distribution of the quadrant screen can be seen in FIG. 2, wherein the first split screen, the second split screen, the third split screen, and the fourth split screen respectively correspond to the first computer and the second screen respectively. A computer, a third computer, and a fourth computer.

The current coincidence point between the plurality of split screen display areas in the receiving terminal is the common coincidence point A of the four split screens. When the user moves the coincidence point A, the coincidence point A needs to be pressed first, when the user presses the coincidence point A. The adjustment switch is triggered. Specifically, the conference tablet can be a smart terminal with a touch function, and the user can directly move by pressing the coincidence point A in the conference tablet, or can configure a mouse for the conference tablet. The user first moves the mouse to the coincidence point A, and then presses the mouse to trigger the adjustment switch. After the user presses the coincidence point A and moves, operation data is generated. Therefore, the operation data includes movement trajectory data of the coincidence point A in the receiving terminal.

S102. Adjust an area size of the plurality of split screen display areas corresponding to the current coincidence point according to the operation data.

The conference panel adjusts the size of the area of the plurality of split screen display areas corresponding to the coincidence point A according to the operation data, that is, according to the movement track of the coincidence point A in the conference tablet. Specifically, in this embodiment, the conference point is based on the coincidence point A. The movement track in the tablet adjusts the size of the area of the first split screen, the second split screen, the third split screen, and the fourth split screen. For example, the user needs to highlight the screen displayed on the 4th sub-screen, just press and hold the coincidence point A to drag, then form the display in Figure 3, and finally release the coincidence point A (the user raises the hand or releases the mouse). The screen displayed on the 4th split screen can be highlighted.

The method for displaying a wireless screen according to an embodiment of the present invention first receives operation data generated when one of the current coincidence points between the split screen display areas of the user mobile receiving terminal is received, and then according to the operand According to the size of the area of the split screen display area corresponding to the current coincidence point, the adjustment of the area display size is added on the basis of the multi-source on-screen display, so that the user can adjust the picture of the source device by operating the coincidence point. Size, reaching key areas of certain areas, enhances the interactive experience.

In addition, as a specific example, referring to FIG. 4, step S102 specifically includes:

S1021: Acquire, according to the operation data, end point coordinate data of the current coincidence point in the receiving terminal after the user moves the current coincidence point;

In addition, please continue to refer to FIG. 2, the boundary of the conference plate can be used as the x-axis and the y-axis of the coordinate system. As the user moves the coincidence point A, the coordinate data of the coincidence point A in the coordinate system also changes, and finally the user is acquired. The end point coordinate data of the coincidence point A in the coordinate system after the coincidence point A is operated.

S1022: Send the end point coordinate data to each of the plurality of source ends corresponding to the plurality of split screen display areas corresponding to the current coincidence point, so that the corresponding plurality of the source ends are The end point coordinate data adjusts the size of the screen image, and sends the adjusted image to the receiving terminal;

In this embodiment, the end point coordinate data is respectively sent to the source ends corresponding to the first split screen, the second split screen, the third split screen, and the fourth split screen, so that the first split screen and the second split screen, The source end corresponding to the third sub-screen and the fourth sub-screen adjusts the size of the screen image according to the end point coordinate data, and specifically, according to the user's operation of the coincidence point A, the area of the first sub-screen and the display area of the entire conference tablet And the coincidence point A in the coordinate system of the end point coordinate data to re-adjust the image size of the first split screen, and then the adjusted image is encoded and sent to the conference tablet, the other split screens are similar.

S1023: Display the adjusted image sent by the corresponding plurality of the source ends.

Finally, the adjusted image transmitted from the source end corresponding to the first split screen, the second split screen, the third split screen, and the fourth split screen is displayed.

In addition, as a special case, the method further includes:

If yes, transmitting, to the source end corresponding to the largest one of the plurality of the split screen display areas corresponding to the current coincidence point, request information for increasing the transmission resolution and the code rate, so that the source corresponding to the largest one of the areas Transmitting a transmission resolution and a code rate of the wireless screen; and transmitting, to the source end corresponding to all the split screen display areas except the largest one of the plurality of the split screen display areas corresponding to the current coincidence point Stop the command of the screen to make all the split screen display areas except the largest one of the areas The source stops sending the screen data.

For example, after the user moves the coincidence point A, the display screen in FIG. 5 is formed, assuming that the end point coordinate data of the coincidence point A has reached the preset boundary threshold, and at this time, the plurality of split screen display areas corresponding to the coincidence point The source end corresponding to the largest area (ie, the 4th sub-screen) transmits request information for improving the transmission resolution and the code rate, so that the fourth computer improves the transmission resolution and code rate of the wireless screen; and coincides The source end corresponding to all the split screens (ie, the first split screen, the second split screen, and the third split screen) of the plurality of split screen display areas corresponding to the point A sends a command to stop the screen transmission, The first computer, the second computer, and the third computer are caused to stop transmitting the screen data. In this case, when the coincidence point reaches a certain boundary, the area adjacent to the boundary is too small to exist, so that they can be prohibited from continuing to encode the screen. At the same time, the receiving terminal can At the source of the display, tell them to improve the clarity of the code and improve resource utilization.

In addition, it can be understood that when the number of the source ends is two, the coincidence point may be one or more points on the split screen edge of the two source ends. When the number of the source ends exceeds 4, for example, refer to Figure 6. The number of the source ends is 9, and multiple coincidence points are generated. When the user operates the coincidence point B, the coincidence point B is the current coincidence point, and only changes and The display area size of the four sub-screens adjacent to the coincidence point B, that is, the display areas of the four sub-screens corresponding to the coincidence point B, does not change the size of the display area not adjacent to the coincidence point B.
