HDTV can be a pure HD Signal : Source HD 16:9, editing HD,
Transmission in 16:9 HD.
HDTV 'upconvert' (Not pure HD): Source 4:3 analog or digital,
Edited in 4:3 Std Def, Upconverted to a 4:3 HD
Signal with black side bars....
SDTV Digital: same as HDTV upconvert, except Step 3
is a 4:3 Digital signal with Gray sidebars...
Does this have to do with each
> station, or is it the TV?
This has to do with each stations Digital Transmissions...
and a slightly lesser extent the TV...
Except some TV's like Sony's CRTs may have better guts to
give a better upconvert/picture presentation..
