The last laugh has already been had many times. The last seven years
have been a waste which cannot be recovered even if 8-VSB was perfect
tomorrow. The disaster is already past tense.
You have many companies pursuing COFDM for all kinds of uses. How many
are working on 8-VSB? At what price? There are five ventures proposed
for mobile DTV in the US all of which will use COFDM, Crown Castle,
Qualcomm, XM, Sirius and another. I don't know how real XM or Sirius
are though. None of them would consider 8-VSB. Even in Korea they are
using DAB and DMB for mobile.
No, 8-VSB has a half life of under 10 years as a fixed service in a few
countries and then only because 5th generation is barely good enough.
The typical home will have 10 COFDM receivers for every 8-VSB receiver
in a few years.
