I disagree. There will be no outcry because very few people will bother t= o try, and thus not notice how unreliable indoor ATSC reception is.

The vendor community is wal= king away.. I think the vendor community walked away several years ago. But I still c= ontend that there is a market for "letter of the law" junk 8-VSB receiver= s. The CE mfrs must put SOMETHING in those DTV sets to satisfy the mandat= e. Since almost nobody will use those receivers, the operative phrase is = "the cheaper, the better." Suppose, for example, there was a performance = issue with closed caption decoders, such that a robust decoder added a no= ticeable dollar figure to the price of a TV set. How many consumers would= voluntarily spend more for a closed caption decoder that "really works w= ell?" How many would opt for the "junk" quality decoder that was only so-= so, but added $0 to the TV and was only included to satisfy some federal = law? DN insert: Of course. This is just going through the motions: don't actua= lly *WANT* to incur the cost to make it work. CEA of course talk about AT= SC enabled sets: the more interesting real world figure would be ATSC *CO= NNECTED* sets to antennas.. A very small number. >Now a 'completely new and unproven digital modulation technology': wasn'= t >that what they said about COFDM in the period 1993-1998?. They are not >laughing now.. You're absolutely right. Now I'll remove my tongue from my cheek regardin= g the idea that "it may take a few more generations to get it right." I t= hought you'd pick up on my sarcasm there. = DN insert: Alas, yes. COFDM does not really have a viable competitor now.= n=3D infinity for the 8VSB decoder that works. Its only the fantasists o= n this list who think its going to come good: economics has killed off an= y interest in fixing 8VSB. There comes a time when you have to a)either t= hrow in the towel and adopt the other system b) reinvent the wheel or c) = ditch OTA TV altogether (unless you retain NTSC). Economics, like death, = is final. >What a tragic mess US DTV has become! DN insert: I was referring solely to terrestrial digital television in th= e US, not the other systems, which as elsewhere in the world are doing ve= ry nicely. On the contrary, it's moving along quite nicely. The quantity of HDTV pro= gramming continues to grow, as do the number of HD displays in consumers'= homes. Satellite is 100% digital, with more HD capacity on the horizon. = Cable has fully embraced HDTV and is moving rapidly to 100% digital simul= cast of analog channels, in preparation for the eventual shut-off of its = NTSC tier. IPTV from the telcos is coming soon, and even wireless DTV on = hand-held devices. American consumers will soon have a plethora of wired & wireless DTV deli= very choices -- all using distribution networks that work. In that presen= t and future digital entertainment world, 8VSB is but a minor footnote of= passing historical interest. And ATSC will be most remembered for giving= us a few "standards" that will withstand the test of time -- like 16:9, = 1080i and 720p, DD 5.1 -- and for at least a few more years, MPEG2. DN insert: Leaving the one *free* distribution network that does not work= to wither on the vine and die! The 'other' system had implemented 16x9 b= efore ATSC and 5.1 is Dolby IPR. As for MPEG2 that was a global standard = whose retirement home is beckoning on the horizon..
