NCast Telepresenter Reference Manual
In addition to these three modes of operation there is the following additional functionality:
Webcasting to Desktops – The Telepresenters can generate RTSP media streams which
may be unicast to desktops or laptops that wish to join a conference. Commonly available
client players allow these presentations to be displayed either full-screen or in a window on an
individual’s monitor or LCD display. In addition to the Desktops using RTSP, remote
Telepresenters connected via multicast can receive the media streams. For optimum
performance consideration must be given to the bandwidth requirements for all senders and
receivers.
In this mode of operation questions and comments from students or the audience may be
enabled through use of any number of popular instant messaging applications (e.g. Jabber,
Yahoo Messenger, Google Talk, etc.).
Multicast Bridging – Through the use of N-Way technology and services, multiple
Telepresenters, which are not situated on a native multicast network, can participate in a
conference through the use of a bridge. The N-Way bridge can also serve as a distribution
point for RTSP unicasts to desktops.
