METHOD AND SYSTEM FOR RECORDING AND PLAYBACK OF WEB-BASED INSTRUCTIONS
Document Type and Number:
WIPO Patent Application WO/2017/063287
Kind Code:
A1
Abstract:
An effective method and system for recording and playback. During a web-based instruction or online conference process, the method and system can record functional operations of a user using a multimedia whiteboard, speaking/talking voices, conversations with other users and/or conversations such as teaching, and separately form different data streams; these data streams are marked by uniform timestamps generated by a web-based instruction system, rather than recording the whole event by stream media; therefore, a web user can conveniently download, from a cloud server or a local area network server over a network anytime anywhere, various data streams needing to be played back, a client of a user terminal obtains the data streams by means of reproduction according to the timestamps after the web user obtains the data streams and then presents the data streams to the user by means of organic combination, thereby completing an on-demand browsing.
