Image dragging transmission display method and system

Abstract

The invention discloses an image dragging transmission display method which is applied to the remote control process. The image dragging transmission display method includes the steps of detecting that the position of an existing window is changed on the local side, and displaying the existing window at the new position in a substituted mode on the network side. According to the image dragging transmission display method, the occupancy rate of processing resources and the occupancy rate of transmission resources can be effectively reduced, and the processing speed and the transmission speed can be increased.

Description

[0001] The patent application of the present invention is a divisional application of the Chinese invention patent application with the application date of February 21, 2011 and the application number of 201110041293.4 titled "A method and system for transmitting and displaying dragged images". technical field [0002] The invention belongs to the field of remote control, and in particular relates to a method and system for transmitting and displaying drag images. Background technique [0003] The so-called remote control means that the administrators communicate with the controlled computer in a different place through the Internet, display the desktop environment of the controlled computer to their own computer, and configure the controlled computer in a different place through the local computer. Modifications, etc. [0004] How Remote Control Works: Remote control must be done via a network. The local computer is the sending end of the manipulation command, which is cal...

[0006] Because VNC is an abstract tool, it has no direct connection with the graphics system of the client machine. VNC technology captures the entire screen of the controlled terminal, and transmits the screen as a bitmap to the host terminal for display. Therefore, When the user of the client computer drags a window to move on the screen with the mouse, the VNC technology also needs to continuously capture and transmit the entire desktop to the host control end for reproduction, and the amount of transmitted data will inevitably be large. Reappearing the screen will also consume more resources, and the transmission efficiency and processing efficiency are very low, which will directly lead to the slow update speed of the picture displayed on the main control terminal, the picture lags seriously, and the refresh effect is not obvious, thus affecting the main control. The remote control of the control terminal to the controlled terminal gives the user of the controlled terminal the feeling that the response of the remote control main control terminal is very insensitive, and there is a very large delay
