A couple of things intrugue me about TV production:

1. How are the backgrounds and floor effects done on shows like Dancing on
Ice and Who wants to be a Millionaire. If projected, why don't the
presenters get in the way?


2. When cutting from one scene (in a drama) do they often cut to the new
sound - ahead of the picture? I suppose it is for some artistic reason -
but I can't appreciate it.

Incidentally - If you never watch TV, There is no need to tell us.

Although I don't watch either and therefore don't know what they are
showing, try Googling "Green Screen" or "Chroma Key".
