An RTP-based synchronized hypermedia live lecture system for distance education
In this article, we have introduced a “Live Synchronized Hypermedia Live Lecture (SHLL) System” using RTP to synchronize the live presentation of streaming video lecture, HTML-based lecture notes, and HTML page Navigation Events. The SHLL framework consists of three major modules: (1) SHLL Recorder- for recording the temporal information of the AV lecture and the HTML-based lecture notes navigation processes. (2) SHLL Event Server- for receiving, depositing, and multicasting SHLL events. (3) SHLL Browser- for presentation of the synchronized AV lecture and HTML-based lecture notes navigation. To manage the synchronization presentation of different media, we have proposed an RTP-based Multi-Sync synchronization model, which account for the human perception factors. To evaluate the performance of the proposed SHLL framework and synchronization model, a RealSystem-based prototype Synchronized HTML-AV Distance Lecture System has been implemented using Java/JavaScript and C. The protot...
