As far as the USA:
You can get HD off-air in some locations for nothing. Getting HD from
a cable company normally involves a subscription to "digital" service
and sometimes even an additional fee for HD.
Some cable system do transmit some HD channels as unencrypted QAM. As
an example I can receive TNT and Discovery in HD with an HD-3000
card, but I think this is technically "stealing" as I have only a
subscription to analog SD channels. My guess is that in time
unencrypted QAM will become even rarer than it is, it's probably
simply caused by ignorance or cheapness on the part of some smaller
Getting HD from the satellite operators requires an additional fee as
well, both for the receiver and the service.
So the only "free" HD is the off-air channels in some markets. I can
receive only 1 ATSC channel and the "HD" programming is mostly just
upconverted SD stuff sent as 720p, only some prime-time and some
weekend sports programming is transmitted in 1080i and it looks like
crap as it is transported to the affiliates as MPEG-2, decoded at the
station so they can switch, insert etc., then re-encoded to MPEG-2
for ATSC transmission using a crappy encoder.
