TDN to be replaced by DMOL

The technical guardian responsible for co-ordinating changes to the digital terrestrial platform (including the allocation of channel numbers) is to be replaced by a new, more formal organisation. DTT Multiplex Operators Limited (or DMOL) will take over from The Digital Network (TDN), but will continue to be owned by the BBC, National Grid Wireless, S4C Digital Networks, ITV and Channel 4.
