I don't know of anyone's definition that includes an ordinary 4:3 analog
set. There is an ETSI definition that includes 480p. CEA requires the
ability to deal with 1080i or 720p and to display it as 16:9, though
that display may be on a 4:3 screen. Their biggest internal argument
was whether the 16:9 within the 4:3 had to be 1080 or 720 or could be
810 or 540. If I recall correctly, the latter position won.
TTFN,
