This is a copy of a comment I made on the "Truth in HDTV advertising" article:
I may be stupid here, but I've been combing over the ATSC website as well as the federal government's DTV website, and nowhere can I find any regulation regarding horizontal resolution in the HDTV standard. Now, for a 16:9 screen it's easy to do the math and come up with 1280x720 or 1920x1080 assuming square pixels, but, again, nowhere on the government's website can I find a reference to this. I can't findany reference to square pixels, either. The only reference I've found so far is defining vertical resolution.
Can anyone point to where horizontal resolution is specified for HDTV by the feds? Thanks.
