I don't accept ... from seeing the level of detail in the picture ...
that this is just an upconverted NTSC signal. Yet it's 4:3, which rules
out most of the HDTV standards (most of them are "widescreen"). The
"HDTV" light on the cable box is on (yes, that might only mean that it's
digital), and it's on a channel (all 500-599 channels in this cable
system) that is supposed to be exclusively HDTV. I note that 1024x768
is a 4:3 format that is one of the approved HD formats, so 4:3 aspect
ratio does not always, automatically, mean it's SD and not HD [However,
I don't think that's what they are broadcasting]. Most likely this
signal [Brian Williams NBC nightly news] is 640x480 progressive scan
with a 60Hz refresh rate. That is a lot higher quality than standard
NTSC analog TV (more than twice the data rate), although no 480 line
format is considered to be HDTV.
