Completely OT - Distributoin Hardware Question

With all the knowledge I've found here....I'm sure someone can answer this......

Our school has a video distribution system. One piece of equipment seems to have "died". Since I can edit video.......in the school setting that means I know everything about video. So I was called in to "help". I know very little about the dstribution process. The video is inputed into the system from 3 satelite receivers and a bank of 8 VCRs. They are run through a video patch bay and into a piece of equipment which takes 5 Composite RCA inputs, monitors whether the unit is on and running with LEDs, outputs it to 5 different TV channels, and into a second patch bay for distribution. (all equipment is rack mounted).

My question.....what is this unit called? I have searched for RF modulators, swtichers, distribution amplifiers.....and can find nothing. I have searched for the name on the unit and found nothing (Dak Net MPV4...I think it was).

Any help would be appreciated. And if I annoy the Forum police...my apologies.

when you say it is outputting to 5 tv channels I assume it has an F connection as an output? Sounds like like a modulator. Then usually there are buttons on the front for setting the output channel/freq. of each.(sometimes just two buttons)
.
But you also said it goes to another patch bay (rca connections of F connectors)If they are F conn. Maybe you are refering to a distribtion amp. possibly a channel plus CP-DA550HHR .
Have you looked at Markertek's website to see if you could identify it?

What they'll be doing is modulating the A/V onto 5 channels and then using a RF distribution amp to split that into mulitple feeds. At the other end normal TVs are used to tune in the 5 channels from the modulator.

You can check if the modulator is working by feeding that straight into the RF in of a TV. As its got five channels if that's what's died I'd be thinking power supply.
