[opendtv] Re: Demand for free DTV rising in Australia

How relevant to anyone is the relative performance of PAL receivers versus
NTSC?

 

This is not to say that receivers shouldn't be better in the areas of
sensitivity ad selectivity and rejecting interference .

Purely from an academic point of view, I would have thought all you
engineering types would always be keen to do up to date comparison testing
of what has historically been 2 distinctly different modulation techniques.
How do you actually know where ATSC is compared to the latest DVB-T receiver
performance if it has not been tested recently. There could be quite a gap
or none at all. It would be a sad thing if we just "assumed" that the
theoretical or stated receiver specs implied actual performance in the
field. 

 

As I recall, original assumptions about a theoretical 3dB advantage to ATSC
evaporated in real testing -then. Where are we now?
