So, every ATSC receiver sold prior to 5th generation is non-functional?
As I recall, while I was personally being attacked by organizations
supporting 8VSB, one of the objections to switching to a COFDM based system
was that such a switch would disenfranchise "all" (all 1000 of them I
guess) of the previously sold ATSC receivers. So the weakness of the ATSC
8VSB design requires a 5th generation receiver, that no one is selling yet.
Hmmm. Is the scent of a class action lawsuit in the wind to compensate
all of the consumers of ATSC receivers that are 4th generation or older?
