Actually, it's MPEG, not JPEG, in this case.  (Although the inderlying
principle -- the Discrete Cosine Transform -- is the same in both JPEG
images and MPEG C-frames.)

In any event, it's also an indication of an over-compressed signal, as
when certain public broadcasters try to run PBS HD and a full slate of
multicast feeds on the same multiplex.
