<p>For example: I'm sure you have seen those stupid pop-up ads
that usually appear on the bottom left hand side of your TV

No. I don't know what you're talking about. You could be referring
to one of two things. If you're talking about those station logos
and other graphics from the broadcaster, those images are cooked
into the video itself, and cannot be removed without doing some very
difficult speculative reprocessing of the video. If this is
something some special popup your cable box displays, then it is
receiving special cues from the cable company, and rendering that
locally. No third party device would ever see that popup.<br>
<br>
I would absolutely LOVE if the ATSC spec actually supported such
graphics independent of the primary video stream. That way, weather
warnings and news tickers could actually be ignored, rather than
wrecking a recording you're watching six months after the fact, with
information no longer of any relevance.<br>
