I have a vBrick 4300 dual MPEG4 encoder. It
support unicast & multicast delivery. Unicast
works fine with QT, Real & Windows Media players.
Multicast doesn't work at all and I'm hoping this
group will have some useful feedback.
The 4300 and my 3417 IPTV starter system are on
the same layer 2 network and subnet. This is a
multicast aware network.
If I use sdr & Ethereal to examine this network
I see SAP announcements and audio & video streams
from the 4300. The interesting this is that none
of my mbone tools can play the content.
I assumed that the IPTV viewer with the "Use
SDP listener" check box checked would hear the
SAP announcements from the 4300. This is not
happening. I never hear the announcements and since
IPTV doesn't allow me to specify the audio & video
group and port addresses I cannot manually play
Does anyone have experience with this type of
arrangement or can anyone shed some light on why
IPTV doesn't at least hear the announcements?
