Problems solved by technology

[0004] The current video conferencing system usually uses the SIP protocol for session management, and the media stream is transmitted using the RTP protocol. The system needs to install an independent system and client. Compared with operating directly on the browser, the operation is complicated and the applicability is relatively poor.
In addition, the SIP protocol is relatively complex, and simple applications do not require complex protocols, and it is inconvenient to expand for specific services

Embodiment Construction

[0033] The accompanying drawings are for illustrative purposes only, and should not be construed as limitations on this patent; in order to better illustrate this embodiment, certain components in the accompanying drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art It is understandable that some well-known structures and descriptions thereof may be omitted in the drawings.

[0034] Such as figure 1 , 2 As shown in . and 3, a PC screen content sharing interactive control method includes the following steps, wherein steps S1 to S4 are the content sharing steps of the PC screen, and steps S5 to S8 are the PC screen interactive control steps.

[0035] S1. The remote PC host specifies the window that needs to be shared, such as the name of the PPT window and the name of the picture window. The screen capture program will intercept the content of the specified window, and the obtained screen data will be s...

Abstract

The invention relates to a PC screen content sharing / interaction control method, specifically, relates to improvement of an existing method of PC screen content sharing. The PC screen content sharing / interaction control method comprises the following steps that: S1, a remote PC host assigns a window of which the content is required to be shared; S2, screen RGB data are obtained in a shared memory data buffer; S3, a software encoder is utilized to perform encoding and compression on data a YUV420 format so as to obtain H.264 video streams; S4, the screen content video streams which have been subjected to encoding and compression are uploaded to a stream media server through an RTMP protocol; S5, a user logs into a Webpage client address which releases media streams of the remote PC host through a browser; S6, control information is transmitted to the remote PC host through a TCP protocol; S7, the remote PC host parses received control information of a user end and displays the received control information on a PC screen; and S8, screen response effect is presented on a Webpage client which the client logs into. With the PC screen content sharing / interaction control method adopted, a user can directly browse the content of the screen through a Webpage browser, and remote interaction control protocols can be customized, and a lightweight system used for PC screen content sharing / interaction can be realized.

Description

technical field [0001] The present invention relates to the technical field of a PC screen content sharing interactive control method, and more particularly, relates to the improvement of the existing PC screen content sharing method. Background technique [0002] Internet technology has become increasingly mature. In order to meet the current needs of screen content sharing, content display, and interactive communication among multiple Internet users, a lightweight screen content sharing system will well popularize multimedia interactive applications among ordinary users. [0003] The multimedia teaching system is usually built with a specific server and client. When implementing multimedia teaching, it is necessary to install the corresponding client software on all client PCs first, which has poor operability and applicability. Moreover, most multimedia teaching systems lack interaction, and sometimes they only accept the teacher's lectures one-way on the screen, which do...
