A transmission and display method and system for dragging images

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 201110041293.4 titled "A Transmission and Display Method and System for Dragging Images". technical field [0002] The invention belongs to the field of remote control, and in particular relates to a transmission and display method and system for dragging images. Background technique [0003] The so-called remote control means that the management staff connects to the controlled computer in a different place through the Internet, displays the desktop environment of the controlled computer on their own computer, and configures, installs software, Modify and so on. [0004] How remote control works: Remote control must be done through the network. The local computer is the sending end of the manipulation command, called the master control end, and the non-local controlled comput...

Problems solved by technology

[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
