Problems solved by technology

[0009] 1. Screen sharing using unicast to communicate with the client needs to keep the client connected, which requires a high load on the server, and the number of supported online users is limited
[0010] 2. Using the multicast method to communicate with the client screen, the load on the server is small, and it can support a large number of users online at the same time. The problem of the switch can not use the system

Embodiment Construction

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] The invention provides a stateless communication screen sharing technology. The client uses the stateless http communication protocol to actively access the web server to obtain data.

[0050] Such as figure 2 As shown, the present invention provides a screen sharing system for stateless communication, including: screen sharing software 10, web server 20, client 30,

[0051] The screen sharing software 10 is deployed on a host that needs to share the screen, intercepts screen image data at a certain frequency, and sends it to the web server 20,...

Abstract

The invention provides a screen sharing system. The system comprises a screen shareware, a web server and a client side, wherein the screen shareware is deployed on a host requiring screen sharing and used for intercepting screen image data according to a certain frequency and sending the screen image data to the web server; the web server receives the image data sent by the screen shareware, maintains connection with the client side through an http communication protocol, and sends image information to the client side according to the request of the client side; and the client side actively and regularly sends a request to the web server and acquires and displays the screen-capture. The invention also further provides a screen sharing method. According to the screen sharing method and system provided by the invention, non-interactive screen sharing of multiple client sides is supported, the server has a small load, the demand on the network environment is low, and the screen sharing function can be served so long as the client side can surf the Internet and browse web pages.

Description

technical field [0001] The invention relates to the field of computers, in particular to a screen sharing method and system for stateless communication. Background technique [0002] The so-called screen sharing means that the remote client program reproduces the server-side host interface with an adaptable time delay, so that the remote user feels that he is on his own machine to realize a virtual interface environment. At present, it is widely used in distance education, remote system monitoring and other systems. [0003] Screen sharing is divided into two types: interactive and non-interactive. Interactive screen sharing is generally realized through the GUI vector instructions at the bottom of the operating system, such as the remote desktop of the windows system, and the user can operate the remote server host. For non-interactive screen sharing, the screen image is generally copied through the API, and then the image information is compressed by various compression ...
