It's about 10 generations back in the codec and algorithm development.



Yeah, like you know what you are talking about. Not.


Since every station upgrades the software in the HD equipment each time
there is a codec or software change, we should know how many times it is
revised.

OK David lets try out this little poser on you the man with all the
answers. If the IBOC comes out on a ASIC and then the codec changes then
what about all the radios out there with old chip in them? Do they stop
working? Will they only be able to receive stations using the old codec?


Can I field this one? Our AFN satellite receivers have to update themselves
every few months. AFN sends the updates down from the bird and the receiver
downloads and installs them. I'm no fan of IBOC, of course, but I see no
reason that the ASIC (not knowing the particulars of the chip) couldn't be
designed to do the same (Flash RAM or some such).

To bad for the rest of us you had to answer that question. I wanted to
see David fumble it. Spoiler.
