Ten more HD channels on two new Freeview HD multiplexes on air from 2014-18

Ofcom has recently suggested that BBC, Channel 4 and Arqiva plan for an interim Freeview HD service, before a new HD switchover in 2018 - to free up more space for 4G mobile broadband - could be put into service.

Just in case you missed it, in the recently published Securing long term benefits from scarce low frequency spectrum: UHF strategy statemen Ofcom document, footnote 64 is a link to BBC Channel 4 Arqiva - Interim use of 600 MHz for DTT which details "to make efficient use of the empty spectrum Ofcom will need to allocate two Multi-Frequency Networks (MFN) DTT licences to Arqiva".

The proposal suggest that, to allow for the move in 2018 to clear the 700MHz band of television frequencies - for allocation to mobile broadband - that two new DVB-T2 multiplexes are created in the 600MHz band. (see also Ofcom channel bingo II - introducing the bands and More Freeview capacity - COM7, COM8 and COM9 - in the 600MHz band).



The top 20 transmitter sites in the UK are, in terms of coverage:

Crystal Palace (17%), Winter Hill (10.2%), Sutton Coldfield (7.1%), Emley Moor (5.9%), Black Hill (3.6%), Sandy Heath (3.5%), Waltham (2.9%), Mendip, Belmont, Pontop Pike (all 2.7%), Rowridge (2.4%), Bilsdale (2.2%), Hannington (1.8%), Sudbury, Divis (both 1.7%), Craigkelly, Oxford (both 1.6%), Wenvoe (1.4%), Tacolneston (1.3%) and The Wrekin (just 1.1%).

The proposal states that:

"the BBC Executive plans to simulcast a third BBC television service and potentially the BBC Red Button video service in HD, Channel 4 plans to simulcast at least one, and potentially two, television services on the interim multiplex ... rollout of the 20 sites could complete in 2014"

This would, following the Arqiva strategy set out in Creation of Broadcast Layers 7, 8 and 9 in 600MHz released Spectrum - Arqiva 21 Sept 2011 potentially use the following allocations:
