They already do something like that. Not packets, but part of the video
Something over a year ago, we bought a used ReplayTV, model 4
(something). It has commercial skip built in, which allows me to choose
to skip commercials, or not, when I play back something I've recorded.
It works by detecting a fade to black signal (or something like that),
that broadcasters insert just before commercials are to run so that the
local station's equipment can run the local commercial set. (Again,
something like that. I may have some details wrong.) It works most of
the time. Once in awhile, the commercial is from the broadcaster, so
there is no fade to black. I suspect MythTV has something that works in
a similar way.
BTW, later versions of the ReplayTV stopped providing the feature. They
caved in to the pressure from broadcasters and advertisers.
