Embodiment

[0031] Such as figure 1 As shown, a screen projection synchronization method of a cloud conference in the present invention is as follows: upload the PPT file to the server and convert it into a preliminary file; the first client, the second client, and the browser respectively establish communication channels with the server to Realize the synchronization of the first client, the second client and the browser; the first client is a mobile terminal, which obtains the preliminary file and opens it for display and page switching; when the first client switches to any other pages of the preliminary file, at the same time Send a synchronization command to the second client to realize real-time synchronous projection of the PPT file to the second client. Wherein, the first client refers to mobile terminals such as mobile phones and tablet computers with IOS / Android system; the second client refers to mobile terminals such as mobile phones and tablet computers with IOS / Android syste...

Abstract

The present invention provides a screen projection synchronization method for a cloud conference, which uploads a PPT file to a server and converts it into a preliminary file; the first client, the second client, and the browser respectively establish communication channels with the server to realize the first client terminal, the second client and the browser are synchronized; the first client is a mobile terminal, which obtains the prepared file and opens it for display and page switching; when the first client switches to any other page of the prepared file, it simultaneously sends a synchronization command to The second client, to realize the real-time synchronous projection of the PPT file projection to the second client. The screen projection synchronization method of the cloud conference can enable the speaker to use a mobile terminal instead of traditional hardware devices to switch the conference screen, so as to simplify the screen projection operation and achieve the effect of real-time projection screen display; at the same time, this method can realize the remote projection of the conference And a wide range of simultaneous screencasting.

Description

technical field [0001] The present invention relates to the technical field of cloud conferencing, and more specifically, to a screen projection synchronization method for cloud conferencing. Background technique [0002] Cloud meeting is an efficient, convenient and low-cost meeting form based on cloud computing technology. In the process of conference speeches, the speaker often needs to talk about the content of the slides in the form of sliding PPT projection. In order to better interact with the audience, the speaker usually needs to purchase additional wireless control equipment to operate the slides, which is not only extra It adds cost, and it's easy to forget to bring it with you. [0003] In addition, in the existing technology, conferences are often carried out using screen projection technology, which refers to mirroring the screen of one terminal to another terminal, and most of the existing screen projection technologies use Bluetooth, infrared or LAN way to ...
