What exactly were you asking about 1080p? What sort of devices do you expect to be generating a 1080p signal, and what do you want to have receive it? No OTA ATSC signals are being broadcast in 1080p. There's not really enough bandwidth in an ATSC channel to get a good 1080p picture in an MPEG-2 stream, and the standard only recently allowed MPEG-4 streams. There may be some cable channels in 1080p; these use QAM rather than ATSC, which uses less error checking and thus has roughly twice the bandwidth per channel. I don't really know, but cable/satellite companies generally cram more signals into a channel rather than using fewer high-quality signals. If you're talking BluRay, 1080p over component cables is right out due to content protection/licensing issues. But video originating at 1080p24, like film content, has information in its headers that allows a trivial deinterlacing when it is transmitted at 1080i60, so it could look exactly the same on your screen if the TV doesn't screw it up. If you're talking game systems, I think they do support 1080p over component. The other end is the TV, and whether it will do 1080p through its component ports, and whether your component cables are of sufficient quality to support the signal. --Levi /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
