| The number of video conferences conducted
over the Internet has constantly increased during the last years.
The need to archive the multimedia data streams of the
conferences became apparent, and a number of tools accomplishing
this task for audio and video streams were developed. In many
video conferencing scenarios, shared whiteboards are used in
addition to audio and video to transmit slides or to sketch
ideas. However, none of the existing recording tools provides an
efficient recording service for data streams of these tools. In
this paper we present a new approach to the recording and
playback of shared whiteboard media streams. We discuss generic
design issues of a shared whiteboard recorder, and we present a
novel algorithm that enables efficient random access to the
recorded streams. We describe an implementation of our algorithms
for the media streams of our digital lecture board
(dlb). |
