...and another screw case, which might necessitate some adjustable
threshold on what "frozen" or "blank" means (I'd be happy to play
around with it):

I've also seen issues where either the cable co or whoever they're
copying a feed from screws up and loses the feed.  Sometimes it's just
black.  But often some intermediate piece of equipment inserts a
little "No video" text on a black background.  Depending on the
channel (and thus presumably the source), that "No video" message
either stays plastered to the screen in the same place, or it -jumps
around- in a screen-saver-ish manner every few seconds.

So one thing I could do is take your patches & start accumulating a
little clip library of misbehaviors to serve as a regression test.
Unfortunately that might not take all that long... :/
