It works, although we "hide" the transision which is not particularly
neat.  The video/audio cut out or freeze/restart and so on.  Instead the
user sees a nice static picture.  MHEG can do the same - we do do the
same on DTT but without the pretty picture - we do lock screens to cover
up messiness if we can.

However it's not like for like.  And it's not about OpenTV or MHEG.
It's about a video stream reconfiguring mid broadcast.  That's a
different can of worms.
