The decrease in cost and increase in automation of audio visual systems for the classroom has led to widespread deployment of lecture capture within higher education. While a number of studies have examined the effectiveness of such systems within an institution, no study has characterized student background across institutions. In this paper we describe three different lecture capture systems ...

A number of university campuses have undertaken the development of digital classrooms that enable presentation of digital media and digital lecture recording. Deploying the infrastructure for a digital classroom is difficult at best even for a technically savvy person. As people from many disciplines become interested in building similar digital classroom spaces, there is a need to produce a us...

The development of real-time transport protocols for the Internet has been a focus of research for several years. Meanwhile, the Real-Time Transport Protocol (RTP) is a well accepted standard that is widely deployed for the transmission of video and audio streams. The RTP specification, combined with a companion RTP profile, covers common aspects of real-time transmissions of video and audio in...

This paper presents an interactive and cooperative VideoConference Recording On-demand system (ViCRO) designed for remote playback, recording and browsing multimedia sessions over the Internet MBone. It consists of Media Servers, possibly cluster-based, and Media Clients. The interaction multiclient/multi-server is based on the RTSP protocol for streaming control, on the RTP protocol for multim...
