Why can HD video travel from a dish to a receiver over coaxial cable but not from the receiver to the tv?
I hit wondered this for a patch and eventually definite to ask. If HD recording crapper separate from my ply to a earpiece using concentrical telegram ground slope it separate from my earpiece to the tv using concentrical cable?

HD can go from receiver to TV in coax. The demodulated HD signal requires 3 component cables, Y, Pb and Pr, although using HDMI is much more efficient.
For it to go from the reciever to the TV as a Channel 3 signal, this would require the reciever to have an ATSC modulator, making it very expensive, and of course the TV would then need an ATSC receiver. All of this additional processing would degrade the HD aspect of the signal as well.

it can. But you won’t be able to connect it at each end. Your sky HD box can’t output HD through scart or composite and your HD TV can’t recieve a HD signal via the same either.
HDMI 1.0 started being developed on April 16, 2002 by the HDMI Founders with the goal of creating an AV connector that is backward compatible with DVI. HDMI 1.0 was designed to improve on DVI-HDTV by using a smaller connector and adding support for audio, enhanced support for YCbCr, and CE control functions.
