Method and device for synchronously recording and reproducing slides and live presentation speech

Abstract

A method and a device for synchronously recording and reproducing slides and live presentation speech are provided. The method comprises the following steps: first, converting the format of electronic slides into a webpage display format, and storing the electronic slides in a server; then, remotely selecting and remotely playing the electronic slides, synchronously recording live presentation speech when playing the electronic slides through operation at a client, and storing the operation information in the server; and finally, uploading the live presentation speech to the server, packaging the live presentation speech, the operation information and the electronic slides, storing the PPT package in the server, parsing the operation information data, and synchronously playing the slide content and the speech. The device comprises a server, and a first client and a second client which are in communication connection with the server. According to the invention, the slides are remotely controlled, and slide speech is synchronously recorded in the remote control process, so that the problem that the traditional video recording process is complex and costs high, the problem that it is difficult to share a large video online, and the like are well solved.

Description

technical field [0001] The invention relates to slide control technology, in particular to a method and device for synchronously recording and reproducing slides and live speech voices. Background technique [0002] Today, presentations (electronic slides) are widely used in classrooms, meetings, lectures, reports and other scenarios. Especially in recent years, with the vigorous development of the Internet and multimedia technology, teaching videos based on slides have become important materials for online learning. However, the video recording technology of traditional conferences, classrooms and other application scenarios is complicated, and it is very labor-intensive or time-consuming; at the same time, the recorded video takes up a large space and is not conducive to network transmission and sharing. [0003] At present, there are mainly two methods of synchronous recording of slide lectures; one is to set up one or more cameras to shoot the real classroom or meeting ...

AI Technical Summary

Problems solved by technology

This recording method requires a very huge labor cost, equipment cost and time cost

Compared with the first recording method, the second recording method has a much lower cost, but this recording form is generally not suitable for live events, but the speaker operates the slides in front of the computer and records the speech; This form cannot record and restore the event site

This is very unfavorable for network propagation, especially the propagation and reproduction on mobile devices
