It is possible that these services could be used for seven single-frequency networks (SFN) multiplexes, or less if they are used for multi-frequency networks.
Ofcom could assign C37 to a second public service high definitionmultiplex, as it can be received by all aerial groups. This could provide channels/channel/BBC3">BBC three and BBC FOUR in HD, with perhaps ITV 2 HD and ITV 3 HD plus E4 HD, as Ofcom expect to get five HD channels per multiplex by 2013 - Five HD is expected on the BBCB multiplex at the end of 2012.
"The decision has now been taken to reallocate spectrum at 600 MHz for
additional terrestrial television broadcast services and OFCOM is tasked
with the preparatory work leading up to the auction of this spectrum."
