56 Chapter 3
Such a setup would make it possible for students unable to attend a class in person to view it
online. It would also enable students who want to review parts of the lecture later to play an
archived version on their computers.
The streaming setup in this example, shown above, has these features:
m A local network with Ethernet connections to classrooms and lecture halls from which live
presentations are to be streamed already exists.
m A 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.
m The 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.
m The 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.
