[opendtv] 8VSB is Too Fragile for the Real World

I was speaking metaphorically - you can not rely on the service if you are
REALLY interested in the show, like during a football game.  I tried to
watch the superbowl on my then new 37" integrated LCD panel, but the freezes
and drops made it impossible to watch the game.

It has nothing to do with on-screen motion, it does have a lot to do with
dynamic multipath - 8VSB is just too fragile for the real world of dynamic
multipath.  Stephen

  "always during touchdowns" sounds linteresting, Stephen.



  Do these problems ALWAYS show up during fast-moving content?



  Are there stations with fast-moving images that don't freeze up?



  Does it happen during broadcasts of soccer (metric football)?  J

  I bought an Acurian, it does not solve the large echo problem in my
neighborhood.  My most current Westinghouse flat panel with built in ATSC
tuner is only slightly better.  Some channels continue to freeze up, and
always during touchdowns for football games.  It is so tiresome, that I just
use my satellite/Tivo instead.  If all politics is local, then I will always
judge ATSC by reception in my house, less than 20 miles from all of the DC
transmitters.  8VSB does not work as well as the analog service it is
supposed to to replace.

    Quite right Bert,

    I haven't asked John why he has not tried more than a second generation
ATSC receiver so here goes.

    John - why haven't you?

    And to the others who have, has it made a significant difference?

    Can you now cruise along with perfecto reception of ATSC in a built up
area?

    Does the latest ATSC receiver still work until you shut it in a
transmitter cabinet? (Joke)

    Yes, I understand there has been improvement. Time will tell and not
much of that left.

    Regards
    Barry

    I find it really nuts that this is being made into some sort of issue.

    More to the point, did you ask John Shutt whether he has yet tried
    anything more recent than a 2nd gen ATSC receiver, on which to base his
    comments on 8-VSB reception?

    And if he did, when he did?

    As technically obsolete as my 3rd gen Accurian and Digital Stream boxes
    are, and already were in 2005, they were very straightforward to set up
    and get working. With indoor or outdoor antennas. If you read the
    comments of other people who bought them, they were better than any of
    the STB competition, when they were first introduced.
