| No, Hidef according to the spec is minimum resolution of 1280x720.
Then don't label it "hidef" if you don't want to. Aspect ratio is just one
of several parameters available in transmitting video. Perhaps the real
issue is whether there is a way in a given transmission system to actually
indicate "this is <some set of parameters>" for the parameters you choose,
and get it recognized at all reeceiving ends. If you choose aspect ratio
4:3, lines 720, pixels per line 1080, frames per second 24, pixel structure
4:2:2, would it be recognized?
Where we call it "hidef" is a fairly arbitrary decision.
