I was conversing with a guy who said that there is a 80 Mhz A/D chip in every HDTV that digitizes the video signals, then does processing on it before it gets converted back to analog for final display?
Of course things like 480i and 720p could get digitized to up-convert them to the 520/1080 that the unit likes to display.
But what about 1080i native video from a STB? Sure the TV could do some 3:2 pulldown detection, but if it did not need to do that, does the TV still digitize/process/convert the video? Does anybody know?
