Document sharing and document control method and system

Abstract

The invention discloses a document sharing and document control method and system. In a host computer, an appointed document file is shared to a plurality of client computers, an operation instructionfor the document in the host computer is sent to each computer, each computer receives the operation instruction for the same document and executes the operation instruction for the document, and therefore, the document control function of the host computer for a local and each client computer can be realized. Through the document sharing of the computer for the client computer and the sharing ofthe computer for the document operation instruction are shared, so that each client computer and the host computer can synchronously browse and control the same document, and the real-time sharing ofdocument contents and document operations can be realized on a basis of a situation that hardware cost is not increased.

Description

technical field [0001] The invention relates to a method and system for document sharing and document control. Background technique [0002] In conference rooms or classrooms, sometimes it is necessary to share the desktop signal of one computer to other computers. Other computers, so that other computers can also see the content of the document on the shared computer and perform operations such as marking and turning pages on the document. [0003] In order to achieve the above goals, most of the practical applications adopt a one-to-many desktop signal sharing method, that is, the desktop signal of one computer is transmitted to the transit server, and other computers receive the desktop signal of the main computer through the transit server, so as to realize the sharing of the main computer. Preview of computer desktop signal. [0004] In the implementation process, this method needs to increase the hardware cost to deploy the transit server. In order to reduce the cost...

Problems solved by technology

[0005] Since the above scheme involves operations such as encoding and compression of image data and decoding and displaying, it has high requirements on the performance of the computer. When the performance of the computer is insufficient, it will cause picture freezes or delays in desktop operations due to insufficient encoding performance, which will greatly affect user experience

[0006] In order to reduce the encoding burden, some schemes propose a method of encoding the document screen in blocks. Although this method reduces the encoding complexity and improves problems such as stuttering to a certain extent, when the number of client computers increases, the local area network The multicast data in the network may cause data congestion, which may lead to a series of unstable factors such as freezes caused by network delays
