Electronic whiteboard data sharing system based on audio and video data correlation synchronization

Abstract

The invention provides an electronic whiteboard data sharing system based on audio and video data correlation synchronization. A linkage interaction operation relationship between demonstration-playing electronic whiteboard content data and synchronously-acquired demonstration audio data as well as demonstration video data is established by demonstration time synchronization protocol data in the process of providing sharing of the electronic whiteboard content data, so that a sharing party can share correlation synchronization between the electronic whiteboard content data and the on-site demonstration audio and video data; the playback operation can be achieved; the correlation synchronization of playing progress can be still ensured; flexibility, vitality and on-site condition reproducibility of electronic whiteboard data sharing service provided by an electronic whiteboard data sharing system can be effectively improved; and the problems that flexibility and vitality of the electronic whiteboard data sharing service provided on the basis of the prior art are low, and the on-site condition reproducibility is limited can be solved.

Description

technical field [0001] The invention relates to the field of communication technology and the field of network application service technology, in particular to an electronic whiteboard data sharing system based on association and synchronization of audio and video data. Background technique [0002] Electronic whiteboard is an interactive system widely used in education, remote conferences, etc. After installing related software, it can realize functions such as writing, drawing, demonstrating courseware, and annotation on the whiteboard, and through Internet technology, various communication terminal equipment (including computer terminals) , mobile terminal, tablet computer, 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] Applying information inte...
