Cable Scanning
The ATSC card in the CW-3000HD is also capable of tuning some digital cable channels
providing they are unencrypted or "in the clear". There are some additional caveats. Your cable
company must use a QAM256 modulation. Not all of them do. It is the most prevalent
modulation but the cable companies are free to do as they see fit.
This does not mean all those analog channels you got on your "cable ready" TV will show up.
They must be digital channels. Analog channels are not and will not be supported.
If your cable company uses QAM256 modulation for their digital channels you should get your
local HD channel rebroadcasts if you are in the U.S. If you are in Canada you may get nothing.
Canada does not have the "in the clear" requirement for local channels. They may all be
encrypted in Canada.
On some systems you may get more than just the locals. It is completely dependent on your
cable provider. In the U.S. some areas may get a few of the basic cable channels as well as
local channels. In other areas you may get nothing more than locals. You may have to step
through the scanned channels to find "in the clear" channels.
The QAM support is a side effect of the ATSC card. It is a novelty to play with and the bottom
line is we have no idea what you may be able to receive. You may get nothing. You may get a
lot. You may have to hunt for it.
