What happens to 1080i HDTV program signals before they reach our STBs? I'm referring to the frequently mentioned ~1400(?)-pixel horizontal resolution limit for OTA signals.
Say, for example, a station wanted to deliver a full 1920X1080i static test pattern with a typical MPEG2/ATSC encoder. Could the encoder deliver the full resolution without artifacts to a 1920X1080-capable display? What happens with a live broadcast or D5-tape full-motion programming signal that fully 'stresses' MPEG2 encoding? If it's done, how is the encoder restricted to ~1400(?) to prevent artifacts?
Anyone know of websites, say, the operating manual for an encoder, that spells out such limits/adjustments? Thanks. -- John
