No it isn't like HDTV. It's a digital broadcast over AM and FM. Nothing HD about it. Just digital. Quality like XM & Sirius.
The way it works is side channels are activated on an AM or FM stations main frequency. The data rides on both sides of the main carier. HD radios turn the data back into music. Most stations are starting with 2 side channels (HD1 & HD2) with the main station on HD-1 and the 'new channel' on HD-2. You will have to buy new equipment to get these channels. They don't broadcast as far as the main channel either. And AM's, I believe, have to shut off the HD service at night because of interference with the good ol' skywave stuff.
I'm sure some techies can break it down more.

wtss.102.5 ( is this it ?)
wtss,buffalo: 102.5 fm uses a "seperate" frequencey in which it the purpose
is to service the blind, and reads the newspaper. like hd-2 is NOT avail.
on just any radio, as the populus that has this service needs a
different receiver, and it also the second audio on newsChannel-7*wkbw*
is this the same thing..?
it was explained to me, that on the wtss 'stick' about 1/2 way up,
this reading service is where this reading service is emulating
its transmission.

What you are describing sounds like a subcarrier, which is a totally different thing than HD-2. People often interchange the two terms which is not correct.
A subcarrier is transmitted analog style above the human hearing range, and converted back to where you can hear it on the recieving end. Muzak, NOAA weather and services for the blind are popular uses.
"HD-2" is the brand name of IBOC Subchannel (In-Band On-Frequency Digital + subchannel). It's a bunch of zeros and ones transmitted in a manner similar to a modem, although it is one-way.<P ID="signature">______________

Thank You/Inquiry:
thank you for taking the time to post, and post correct
information...only way i can learn more is through
education with facts..
NOW, i have a question, as i always do:
say...market #52, (buffalo-niagara falls) doesn't
"care" about hd-2 broadcasts..can a civilian...
take it upon themselves to use the hd-2 on a
frequencey that is not taking advantage of the technology?
i know, it is a "NO" but..maybe i am asking,
how long could some one do it, before getting caught..
or, the legal way: approach the station and "borrow"
their hd-2 frequencey...hmm ?

You could broadcast your own HD station on any frequency - even on a licensed station's side chanel - problem is - who will hear it, and interference of the main channel since you wouldn't have the same contour of the primary station. Oh, and the getting caught thing...mess with a licensed station, and you WILL be shut down.
You could negotiate with a local station and lease an HD channel from them. I think we'll see a lot of that in the future. Just like we see on almost every AM gawd channel. Brokered time is common place in radio.

Broadcasting on an existing stations side channel without permission would be a very bad idea. Besides that, how is the average joe going to get access to Iboq broadcast equipment, its not like regular FM, where anyone can buy a transmitter online, and begin broadcasting. And like MIKEO says, nobody will hear it anyway. You would be better off with a Part-15 fm, with an online stream. I think in Canada, WHERE YOU ARE, you are allowed to Transmit FM at higher power than in the U.S, I could be wrong though.
