A method for realizing multi-terminal animation collaborative browsing of electronic slideshow based on pictures

Abstract

The invention discloses a method for realizing collaborative browsing of multi-terminal animation of electronic slideshows based on pictures. The PPT content of the present invention takes pages as units, extracts all animation information of each page and exports a picture according to the animation execution steps of each frame of animation results, and packs all animation result pictures and animation description information of each page into a data package in Zip format. Then, a data package in Zip format per page is transmitted to all remote interactive participants through the network, and then each remote terminal completes browsing based on pictures. The present invention has the processing of the third method mentioned above is very simple, and at the same time avoids the problem that the PPT content of each page is converted into a static picture, and all animation information of the PPT is lost. The present invention can realize the animation effect to meet the needs of users in most cases; the present invention uses lossy compression in the case of satisfying the visual effect, maximally reduces the amount of data transmission, and effectively saves bandwidth.

Description

technical field [0001] The invention belongs to the field of online live broadcasting and computer graphics and image processing, and provides a very convenient technical method for PPT electronic slideshow multi-terminal animation collaborative browsing application, which can reduce the amount of data transmission to the greatest extent while satisfying the visual effect, and effectively save bandwidth. The application scenarios are relatively wide. Background technique [0002] PPT electronic slides are widely used in business, teaching, training and many other fields; the current very popular online live broadcast field is also widely used to realize remote real-time interactive browsing by multiple people. In online live broadcast, there are generally the following methods to realize remote real-time interactive browsing of multiple people: [0003] The first method is that the lecturer transmits the original PPT document file to the server in the form of file sharing, ...

AI Technical Summary

Problems solved by technology

The advantage of this method is that the processing is very simple, but the disadvantage is also very obvious, all the animation information of the PPT is lost

[0006] The above three methods all have obvious defects or problems in applicability and complexity. We need a method that can achieve animation effects, is relatively simple and fast, supports multi-terminal use, and is economical and practical.
