Digital Over Air Tv Signal uses basically the same equipment as any broad-band antenna system. The digital channels will be transmitted on High Band VHF ( Channels 7-13 ) and UHF ( ch 14-68). Analog will go away February 19, 2009.
If your MATV system of amplifiers and Passives cover VHF High Band and UHF you should be OK as long as you have new TV's that have ATSC tuners that are capable of processing new digital transmissions or you get converter boxes for any TV that does not have the new type tuner.
In some cases you may need to boost up your signal using better UHF antenna, Pre-amp or distribution amplifier.
Larger MATV systems. In large systems it is common to convert UHF channels to VHF then use single channel strip amps to boost the signal. They do this because VHF travels through a system with less loss. You are able to build a bigger system and use less line amplifiers. If your MATV system has single channel strip amplifiers you will have to make some changes and some decisions.
If you want to keep all your old TV's you can get Converter boxes for the head end to convert each digital channel you want to keep on your MATV system. You then need to get modulators that take the AV output of the converter box and modulate it on to your old channel strip amps. This will keep the channels as well as let you add some new channels by getting more converter boxes, modulators and strip amps.
This will work for you as long as you can get TV's that have analog tuners which should be a long time as TV's usually have tuners that receive cable channels 2-125 which is what you will be using.
You do not use the ATSC tuner in the TV so the signal although, probably better than ever, will not be HD quality. This will show up on a large screen TV.
Commercial products that do this are quite expensive. If you want to try it on the cheap you can use the home type converter boxes. but you will need to plug them into a good standby battery backup ac power supply because when the power goes out they do not come back on the channel you have them set for.
The other option is to redo the system to distribute the new digital signal around the building. If you do this any TV's that do not have the NEW digital tuner will need to get digital to analog converter boxes.
