The TCI/AT&T DCT I have does |mpeg compressed NTSC over a digital coax link. Digital TV (of which, HDTV is |one standard) isn't NTSC at all. Slashdot has an interesting story today |about HDTV v.s. NTSC, etc... Thanks for the pointer. This has some good info. In particular, a few of the slashdot article responders discuss something a friend of mine was telling me: that an encoding that some of the HDTV broadcast stations are using (and doubtless the HDTV cable folks are considering), is just digitizing, compressing, and jam-packing 4-6 regular NTSC signals into the 6MHz chunk previously allocated to one signal (or just transmit one NTSC-encoded channel, and use the other 75-83% of the bandwidth for "other services"). Pure profit, if they can convince anyone to buy a digital TV for that... An article one slashdot poster mentioned also discusses this and is a good browse (it's looong): http://www.wired.com/wired/archive/5.02/netizen.html?pg=3&topic= The Great HDTV Swindle The section on the CICATS standard is pretty funny.
