Example Embodiment

[0033] The present invention will be described in further detail below.

[0034] Based on the picture to realize the method of multi-terminal animation collaborative browsing of electronic slides, the general idea includes: PPT content is page-based, extract all animation information on each page, and export one picture per frame of animation result according to the animation execution steps, and all animations on each page The resulting picture and the description of each page of animation are packed into a Zip format data packet. Then a data packet in Zip format per page is transmitted to all remote interactive participants through the network, and then each remote terminal completes the browsing based on the picture. The present invention is equipped with the aforementioned third method. The processing is very simple, and at the same time, it avoids the problem that every page of PPT content is converted into a static picture, and the animation information of the PPT is all lo...

Abstract

The invention discloses a method for realizing multi-terminal animation cooperative browsing of electronic slides based on pictorialization. The PPT content of the invention takes a page as a unit, extracts all the animation information of each page, derives a picture according to the animation result of each frame in the animation execution step, and forms a Zip format data packet from all the animation result pictures of each page and the animation description information of each page. Each page of Zip packets is then transmitted over the network to all remotely interacting participants, andeach remote terminal completes the browsing based on the picture. The invention has the advantages that the processing of the third method mentioned above is very simple, and at the same time, the problem that each page of PPT content is converted into a static picture and all the animation information of PPT is lost is avoided. The invention can realize the animation effect to meet the needs ofusers in most cases. The invention uses the lossy compression under the condition of satisfying the visual effect, maximizes the reduction of the data transmission quantity and effectively saves the 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, ...
