I will repeat myself.
TV streams are either analog or digital.
TV streams are either standard definition or high definition.
Analog streams cannot do high definition.
Digital streams can be SD or HD.
And HDHR is a digital tuner.
It tunes the the desired stream.
The stream may be an SD version of the same 'channel' which is being
broadcast in HD. Many TV stations do that with OTA broadcasts: channel
7-1 is HD, while 7-2 is SD.
Cable TV can be analog or digital. Digital streams are usually (North
America) QAM256 encoded. In addition they can be encrypted. Whether
unencrypted or not, the stream can be SD or HD. Generally, the 'premium'
encrypted content is HD, but not always..the channel may generally be in
HD but beoadcast lots of shows which are SD.
Whether an HDHR will receive anything useful from your cable depends
upon your cableco. If in the US, you will at least receive the 'must
carry' local broadcast stations (SD and HD versions), plus whatever the
cablco decides to allow. In Canada, cablecos can set the encryption bit
on every digital channel, and some do (Rogers in the Toronto area) while
some do not (Shaw in Victoria did for a little while, but reversed itself).
When Rogers changed to encryption, I lost about 25 digital channels on
the cable. I already had an HDHR...and I had an antenna mounted in about
10 days! I now get 12 good OTA digital channels and will likely get more
when I put the antenna on a tower (its in the attic now).
