DTG propose SFN HD multiplexes plan

The Digital Television Group, who slammed Ofcom’s plans to squeeze HD channels onto a vacated multiplex B last month, have put forward their own radical plans to launch high-definition channels on Freeview. Their suggestion involves the creation of two entirely new multiplexes, to be broadcast as single-frequency networks (SFNs, i.e. broadcast on the same frequency nationwide) which could carry 12 HD stations between them, rising to 40 (yes, forty) as technologies improved.
