ABSTRACT
Voice and video conferencing on the Internet is about to become a lightweight day-to-day application. This trend follows from high-bandwidth data connections, which are increasingly available to the public at reasonable prices. There is also some remarkable progress in video/audio compression algorithms, which reduce a media data stream considerably and reconstruct it again to a high-quality playout sequence on the receiver site. Furthermore, battery powered mobile devices rapidly gain processing and communication performance. They currently can host desktop conferencing software, thereby seamlessly using any Internet connectivity available.
