National Conference - Need audio solution, will SC work?

Fed-X · 3rd March 2004, 07:39

I have done some searching but have been unable to locate some of the info. that I need.

Our organization (online based community) is having it's second National Conference this Month and a great many of our members are not going to be able to physically attend, therefore I thought (rather late in the planning stages) we might be able to stream a live audio feed from the conference..

At this time it looks like I may not be able to get a T line "installed" before the conference date and they don't offer wireless or dsl/cable in this hotel. The only thing I know for sure is that it will have a couple phone lines.

Here are the questions I have and again, I apologize for not being able to search more and see if they are already answered but I have to hop a flight and I am running out of time.

1) Can I "broadcast" or have a successful upstream connection to a server on a dial up line? What is the minimum "bandwidth" requirements?

2) I have a Dual Xeon P4 server with LOTS of bandwidth to spare. Can I install Shoutcast server on here for the one day broadcast or would it be better to go with someone that already has an established server? Also, if using my own server, what is the load per connections other than the obvious bandwidth? I've got 2 Gigs of RAM and plenty of free resources..

That is all I can think of right now.. Thanks for your time,
David

Nobody?

Bueller?

1) Depends on the dialups upload bandwidth. A 56k modem may be able to listen to a 24kbps stream, but I don't think it can source one. Might be able to do a 16kbps or 8kbps. If it's a voice only transmission, this should be fine. Telephone quality.

2) From the DNAS read me:

Quote:

* 90Mhz or faster server, running one of Windows 95, 98, NT, 2000, ME,
Mac OS X, Sparc Solaris 2.7+, FreeBSD 4.x+, or Linux with a libc6 kernel.

* 14kB of memory for every listener you want to broadcast to (i.e. 1,000
listeners means you need 14 Megabytes of RAM), plus whatever your
operating system needs for overhead, plus 1.5MB for the server's
base requirements. Don't set the listener count higher than you need,
it just screws things up.

* Enough bandwidth to run the server. If you want to broadcast to 100
listeners at 24kbps, you'll need about 24kbps*100 = 2,400kbps = 2.4Mbps
of bandwidth. That's about 2 T1 lines worth of bandwidth. Trying to
push 100 128kbps listeners down your 768kbps cable modem isn't going
to work

Using your own DNAS will save some money but depending on your network configuration and familiarity, setup may be challenging.

FesterHead,
Thanks a lot for the information! My server admin is checking out the config for using our own server vs. someone else's.. My main concern was the uplink. Since we are going to just be using it for our conference's speaking and no music, it sounds like it may just work.
Thanks,
David

If you want an actual conference solution http://www.fwdnet.net provides a VoIP SIP service with conference calling. Only thing is everyone listening to the conference will need to download a softphone. The plus is you can have more than one person in the conference talking.
