Regional multiplexes C and D planned?

National Grid Wireless has appointed a new Service Information Manager for it’s two digital terrestrial television multiplexes (C and D) which could enable the broadcasting of regional services. In other words, they’ve spent some money on a machine that will let them show different things on multiplex C or D in different parts of the country. At the moment, this can only be done on multiplexes 1, 2 and A (mainly for showing regional programming on the BBC and ITV, as well as regional advertising for the big commercial broadcasters).
