That's understandable for OTA HDTV broadcasts. If the set has a built-in
ATSC (HDTV) tuner/decoder it can read the aspect ratio flags straight
off the digital stream.
But what about playing back DVDs (which is what the original question
was about)? How does the DVD player tell the tv set "this signal is
full-screen 16:9" or "this signal is full-screen 4:3"?
