QT broadcasting is not designed to be a near-zero-latency product for,
say, video-conferencing. There are intentional buffer points between
the broadcaster and client that are used to improve the chances of
delivering a very high quality (no packet loss, no too-late packets)
stream to the viewer.

Hi Joel,
I tried again with the live video streaming: (using SONY DV camera)
. choose LAN-slow-motion with 15 fps.
. start broadcasting with 0 buffer
. 1 minute later, start qt6 local mac machine.
. start another qt6 on win2k box located in the same 100LAN.
. Broadcaster displays that 'Total Data Rate' is about
300-400kbits/sec,
and both CPU is 30-40% loaded.
If I wave in front of the camera, I can see it on the broadcaster
window
right away but can only
see it on both qt player around 7 seconds later. Is that normal? Since
there
is 0 buffer on broadcaster
and the qt player, does the delay happen on the QTSS?
I change the kay frame from 1/90 to 1/15 but didn't see too much
difference...
Thanks for your help,
-Chong
