True that is very true. By law though they can't switch over if the opportunity to everyone to be in digital isn't possible, which includes the
coupons. Once the coupons come back then the transition can come back. I would be very mad at the company or program that under made the coupons if I
was a broadcaster.
Want to know why its all such a mess?
In 1996, at the NAB convention in Las Vegas, the HDTV standard was demonstrated for the first time. A side by side comparison of a true HDTV signal at
720x480p resolution with 5.1 surround sound and a standard NTSC 2ch stereo signal were displayed all over the convention floor.
During the first NAB/FCC convention meeting, the FCC graciously stated that it would allow the broadcaster and industry to determine what kind of
format they wanted to choose to transmit on the HDTV adopted transmission standard.
Meaning, a broadcaster can trasmit a full blown 1024x768p hd signal, or a 720x480i signal, or a 1024x768i signal, or a 420x340 semi hd signal with 5
standard NTSC 525 line signals on the same carrier, plus about 12 other different formats.
In basic terms, it is just like the battle of the VHS vs BETA tape war, or the Blu-Ray DVD vs HD-DVD battle. None were compatiable.
Thus because of the blunder back in 1996, to which I stated and had everyone's head turned my way when I spoke up that having broadcasters choose a
format to their leisure would create a bottleneck in the industry and in the consumer television receiver manufacturing industry because each set
would have to have a super-converter capable of converting any and all possible formats it encounters.
That would put the price of HDTV receivers through the roof!!
IT is not uncommon to have an HDTV set or even a converter box, capable of decoding a set number of formats, and run into a channel that it cannot
decode properly.
To keep those converter boxes cheap and affordable for both consumer and government coupon funding, those converter boxes will probably only decode
about 1/3 of the formats possible on the HDTV transmission standard.
So..what does that mean exactly.
It means that because of an FCC screw up, and not listening to the advice of a veteran broadcast engineer...me...they went ahead and allowed all
stations to choose their format. As long as the transmitter sends out that signal in the 8VSB standard, they dont care what resoltution, or encoding
codec they use, or how many audio channels they use.
So even when they roll out more converter boxes, and turn off analog, there will be those that used to be able to pick up stations that cannot now
because their converter box or receiver set does not have the decoding codec capable of decoding that station's particular format they chose to
transmit.
The blunder has only just begun.
