"I had a dream!..."
Thank you Steve. As a Broadcaster I would add that with Hierarchical Modulation
broadcasters would PROUDLY provide Homeland Security / Emergency Services with
a dedicated (effectively seperate) RF channel (4QPSK like in performance) to
serve the (mobile and portable) EBS needs of a democratic Republic.
Also, I happen to think it would be cool to be able to plug a USB device into
my laptop and watch HDTV...REALLY COOL! (720P happens to make sense...)
Sorry, did I just wake from a dream?...
Regards, Mark
