Terminal-spanning real-time interactive online distributing method of lantern slide

Abstract

The invention relates to a terminal-spanning real-time interactive online distributing method of a lantern slide and belongs to the field of a computer science and technology application technology. The method comprises the following steps of: uploading a lantern slide file to a server side from a master control end through an HTTP (Hyper Text Transport Protocol) channel; analyzing the lantern slide file by the server side and analyzing all information in each page of the lantern slide file to a middle format and storing; carrying out interactive distribution on the lantern slide by the master control end to finish playing control and information interaction in which the master control end, the server side and a client are participated; and locally and persistently storing by the master control end and the client. Compared with the traditional method, the real-time online distribution of the lantern slide on each type of intelligent equipment is realized; an autonomous control capability of the client and an interactive communication capability of the master control end and the client are greatly enhanced; and transmission and storage of content and notes are finished in a playing process, so as to get rid of the constraint of a traditional computer and break through the limitation on time and space.

Description

technical field [0001] The invention belongs to the technical field of application of computer science and technology, and in particular relates to a cross-terminal real-time interactive slideshow distribution technology in an online environment. Background technique [0002] With the popularity of computers, it has become a daily habit to use slides represented by PowerPoint slide files to give speeches to express ideas and disseminate knowledge. On the other hand, the network connects all isolated computers, breaking through the limitation of space and enhancing the communication ability. The combination of the two produces a variety of existing online slideshow distribution methods, and the slideshows are distributed to different terminals through the network for synchronous playback. The online distribution method is mainly realized through technologies based on desktop sharing (such as ITU-TT.120 standard protocol) or streaming media technology (represented by Microsof...

AI Technical Summary

Problems solved by technology

The existing technology usually only supports the use of traditional personal computer terminal equipment, but lacks support for intelligent terminal equipment of various sizes and systems that are becoming more and more popular today;

[0011] 2. The client lacks the ability to interact independently

The client is usually in a passive receiving position. In some methods, chat-based communication channels or e-hand raising methods are provided, but the client is still unable to carry out further actions on the slide, and cannot directly record itself during the listening process. experience;

[0012] 3. The distribution step is only for playing the slideshow, but not for distributing a copy of the slideshow

That is, the client cannot obtain a copy of the slideshow while watching the playback
