An Electronic Whiteboard Data Sharing System Based on Subscription Information Publishing

Abstract

The present invention provides an electronic whiteboard data sharing system based on subscription information publishing. By data communication connection between each data sharing device in the system, the electronic content data synchronization of the subscription publishing mechanism is performed between different data sharing devices. At the same time, distributed backup and storage of electronic whiteboard content data is also performed on different data sharing devices. Once the data sharing device as the information publisher has abnormal operation status, each corresponding information subscriber will start the corresponding subscription topic. The allocation and scheduling mechanism of information publishers and information subscribers in the type, the other information subscribers of the corresponding subscription topic type with normal operation status determine the new proxy information publisher according to the principle of the highest subscription priority, and execute the corresponding subscription topic on their behalf The type of electronic whiteboard content data release task reduces the probability of interruption of electronic whiteboard data sharing services, and improves the fluency and stability of information sharing services provided by the system.

Description

technical field [0001] The invention relates to the field of communication technology and network application service technology, in particular to an electronic whiteboard data sharing system based on subscription information publishing. Background technique [0002] Three electronic whiteboards are interactive systems widely used in education, remote conferences, etc. After installing related software, functions such as writing, drawing, demonstrating courseware, and annotations on the whiteboard can be realized, and through Internet technology, various communication terminal equipment (including computers) Terminals, mobile terminals, tablet computers, etc.) can obtain data information on the electronic whiteboard in real time, realize real-time information interaction and sharing with the electronic whiteboard, and apply it to the development of application services such as Internet teaching and online conferences. [0003] At present, the data communication interaction b...
