Method and system for transmitting and displaying dragged image

Abstract

The invention discloses a method for transmitting and displaying a dragged image, and the method provided by the invention is applied to a remote control process. The method comprises the following steps: detecting the existing form which has the position change at a local side; and displaying the existing form at a new position at a network side. By using the method provided by the invention, the occupancy rates of processing resource and transmission resource are efficiently reduced, and the processing speed and the transmission speed are increased.

Description

technical field [0001] 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 [0002] 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. [0003] 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 computer is called the controlled end. The master control end and the controlled end can be located in the same local area network, or two or more computers connected to the Internet at any location. Usually, the server-side program is installed in the computer of the master control end, and the ...

[0005] 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
