If you want to do it for real, take a look at the MLT project: http://mlt.sourceforge.net/ That has support for for example the Bluefish444 SDI cards, and do playout of real broadcast formats, such as DVCPRO, but also regular MPEG formats.
It also provides ShotCut, a really competent Non-linear editor, that can send edited clips directly to playout.
I know it is in use in one of Indias largest broadcasters, and they transmit to millions of viewers. So it would definitely be good enough for a small station like the one you are talking about.
