Hello,

I have a two part question.  

First - I'm interested in knowing where the industry is in the
adoption of digital video technology.  To be specific, I'm referring
to production studios, networks, etc.  I'm mostly interested in the
way video is produced and then switched/routed within a production
environment. I'd like to have this explained in the answer, or direct
me to good articles that show where the industry is (hopefully in
percentage terms) along this adoption lifecycle.

Second part:  By early 2009 the US government has mandated that all
terrestrial broadcasts be DIGITAL. This means that the RF transmitters
have to transmit digital video to household consumers (analog will not
be permitted).  I'm trying to understand how this impacts the typical
TV station.  In theory, a station should be able to continue producing
video whatever way they use today, and if that method is analog, they
would simply purchase an A/D converter as the final step to comply
with the need to transmit video.  Is this correct, or does the 2009
"all digital" law push TV stations to use more digital equipment in
their production process.  The most important part of your answer will
be for me to understand if the 2009 law is a driver for conversion to
digital video production, or is it a red herring, meaning that the
need to go to HDTV will be the real industry driver (and not the law).
