Does seem suspicious
Tony N.,
I too was a Broadcast Engineer. Have seen plenty of interesting and political developments on the road to HDTV. I use to be with WVTV in Milwaukee when much of the early US HDTV testing was going on. If you recall, it was supposed to be an analog system using two channels. What a mess.
I even remember Bill Gates lobbying hard for square pixels, because it would otherwise add "hundreds of dollars" to the cost of equipment to receive and display on computers. (Hmmm, seems to me I can buy a card for less then $200. Does this mean it would be free if the pixels were square.)
Perhaps the biggest swindle/pork barrel was the choice of 8VSB vs. COFDM. Orthogonal Frequency Division Multiplexing would have allowed for a lower symbol rate on each carrier. Besides making it easier to design, and less stringent on traces etc., it would also be more robust at dealing with multipath distortion and other reception problems.
Yes, we have developed better and faster adaptive filters, but this has added to the cost of the receivers. And, the adaptive filters are designed for stationary use. At this time, they cannot adapt too well to rapidly changing signals. Ie. a moving vehicle in an urban environment.
For a bit of history, this would not be the first time that the FCC has mandated extra features on certain TVs.
Remember:
UHF tuners that tuned each station individually, instead of the turret tuner.
V-Chip
Close Captioning. Now there's one that the majority of the population didn't need, and yet added a significant cost to the receiver.
Now, do we need any of those if we have digital cable and/or satellite? Nope.
No UHF or VHF tuners needed whatsoever.
Parental locks are available on the STB.
Close captioning is decoded by my STB.
Perhaps the FCC could mandate digital tuners for any HDTV that has a tuner. This would exempt all those "monitors" out there.
Lastly, we need another F.R.E.D. but this time doing digital reception, not BTSC audio. Larry Schotz, are you listening?
