This is a total noob question (my apologies) but this thread seemed as good as any (short of starting a new one), so here goes:
How is it that HD can be carried through coax from an antenna (OTA), from cable (QAM or pay HD), or from a satellite dish to an HD Receiver, yet I have seen numerous sources (online "basics", news articles, "HD for Dummies"-type things, etc.) that say that HD signal can only be carried by HDMI, DVI, and component cables? In fact, I think I read one place that said coax can only carry 480i?
Obviously HD signals can be carried by standard coax, because all three sources (OTA, cable, satellite) use it. So what is "bad" about coax, that it is not used to go from the STB to the TV input?
I'm assuming that these "info experts" don't list it as a type of cable that can "carry HD" because you never see it used between the STB and the TV?
I'm sure this was explained somewhere previously within this forum, but there's so much info here that it's daunting to find. If it's easier than retyping, just point me to the right thread. Again, my apologies for such a noob question.
