From your description, I can't tell if you're wanting to Multicast from
the QT Broadcaster, or are you wanting to distribute the stream(via
unicast) to 4 destination (receiving) QTSS machines, and then have
each of them replicate the incoming stream as an outgoing Multicast
on their own local respective network?
In any case, let me recommend that you take a look at the
relayconfig.xml-Sample file (it is in
/Library/QuickTimeStreaming/Config/relayconfig.xml-Sample) and there
you will find examples how to do this.
You then will need to place a copy of the .sdp file in the Movies
folder of each of your destination (receiving) QTSS machines, and as
necessary hand-edit the .sdp file so that each one references the
corresponding multicast IP address.
The last step is that to watch one of the multicast source streams via
one of the 4 destination (receiving) QTSS servers, you would then open
up a simple RTSP url targetting one of the 4 destination machines and
refer to the xxxx.sdp filename.
Some of what you want to do might be do-able by using the QTSS
Streaming Web Admin Relay page, but you'll have more control over doing
exactly what you want if you edit directly the realyconfig.xml file.
You'll need to either stop/restart the QTSS processes for the relay
changes to take effect, or minimally use the QTSS Web Admin to stop
(pause), and then start (resume) the server.

Hello all.
I want to understand the procedure for setting up a multicast relay
using QTSS 4 for OSX Server. Basically, I'm broadcasting from QT
Broadcaster, and
I would like to relay the broadcast to 4 remote sites on my company's
network that are set up for multicasting. Each of the remote sites has
QTSS 4. I have a streaming server at my local site, and I would set up
that server as the relay machine. I understand that I would have to
relay to a multicast address, but I need to know the steps of the
control
panel. I keep reading that I have to manually modify the
relayconfig.xml
file, but can't I just set this up using the "default relay" control
panel?
If I do have to modify the XML file, how do people at the remote sites
tune
in to the multicast?
Also, when making the reference movie, would I call the SDP file
via RTSP?
I've been a Multimedia developer for a while, but Streaming Server
Administration is new to me. Any help would be GREATLY appreciated.
