[BC] TV Standards

It was six months.

The problem with COFDM was that since the rest of the world uses 8 Mhz TV
channels (on UHF; unlike the U.S., they required those transmitting color to
do with better transmitters on a new band and with wider channels, this is why
European color TV has always been over 600 lines of resolution), the US uses 6
mHz channels (because we never bothered to upgrade earlier, see above).

COFDM had to be modified to fit in the smaller channel; this took six months
to accomplish. By then the "Grand Alliance" (What's a camel; a horse designed
by committee!) had decided to move forward with 8-VSB, refusing to give COFDM
any more consideration. Sinclair Broadcasting, one of the bigger TV groups
tried to persuade the FCC to allow both systems; their pleas fell upon deaf
ears.

         You'll have to ask the NAB, I would think.

         Any TV folks here who can tell us if
         it was merely six months that left the
         US with an inferior system?
