The streaming setup in this example, shown above, has these features:

mA local network with Ethernet connections to classrooms and lecture halls from which live presentations are to be streamed already exists.

mA digital video (DV) camera and microphone are set up in a classroom or lecture hall to convert the live presentation to digital form. The camera makes a high-quality DV recording of the presentation and provides the digital signal that is to be encoded for live streaming.

mThe DV camera is connected through a FireWire port to a laptop running QuickTime Broadcaster, which encodes the digitized live presentation and transmits the signal via an Ethernet connection to the streaming server on the campus network.

mThe streaming server is a rack-mounted Xserve running “headless” (without a monitor and keyboard). The server is running Mac OS X Server with QuickTime Streaming Server (QTSS) conﬁgured to reﬂect the encoded live presentation as a unicast stream to each client computer on the campus network and on the Internet that “tunes in” to the broadcast. The Xserve comes with Mac OS X Server and QTSS preinstalled.
