Multicast video stream to EIA analog channel

[Matt Bernardi <m.d.bernardi () zitomedia net>]

Hello all,

I am new to the mailing list and wanted to pick some of your guys brains 
about something. I work for a small cable service provider. What I am 
trying to do is receive a multicast stream, modulate it and send it out 
as an EIA analog channel.

I know there is equipment built for this specific reason(RGP SEP, 
APEX1000, etc) but this is just going to be a temporary fix as we are 
doing a total video overhaul and moving to all MPEG4 capable equipment. 
I figured there is a way to accomplish this with linux as my budget 
isn't very large, but all of my reasearch hasn't really helped so I'm 
reaching out to you. Has anyone ever done this? or know of any good 
reference sites for this?

Any info would be greatly appreciated.

Thanks again,
Matt Bernardi
