720p and NTSC safe areas

[MRX37]

Okay bit of a story here. I bought an old external HDD for $10 at a flea market Whoever owned the drive before me apparently worked in the TV sports broadcasting industry until at least 2005.

Among the files were nostalgic ads and references to players like Ben Wallace, I found some technical files and among those, safe areas for both NTSC and 720p HD. Figured I'd share those. Might be of interest to someone here.
