In less scientific terms - DTV (Digital TV) is a requirement (at least in the USA and countries that follow us) for HDTV (High Definition TV). So, when you see all the posts complaining that Fox is "not meeting the mandate" by broadcasting DTV (but not HDTV), it's hogwash - the mandate set out by the FCC was for DTV - HDTV is a logical extension of this (and is definitely to be preferred).
The 18 different formats of HDTV should also be convertible down to what your display can handle - i.e. why in the world would anybody want a 13" HDTV display ?
So, what we need here in the US to get DTV to really take off are some good, cheap convertor boxes (8vsb) that can receive the ATSC signal, then convert / display it on the (literally) millions of NTSC TV sets. This in addition to some programming would help immensely (IMHO) for DTV / HDTV acceptance.
Thanks for clearing this up Ken H. Best Buy has a sign explaining SDTV, EDTV, and HDTV which I did not understand. I understand and can quote from memory all 18 ATSC formats but I did not understand Best Buy's explanation of EDTV. No wonder consumers are confused. Part of my problem at Best Buy was that a salesman put a label in their store on my Toshiba 65" widescreen, that receives 1080i over component cables, as EDTV not HDTV ready.
