The Inquirer: OFCOM has published its plans to revamp the UK’s digital terrestrial television system to enable HDTV services on digital terrestrial system, Freeview.Operators will be required to adopt 64-QAM encoding, which enables more channels to be broadcast per multiplex.
Currently, only a couple of the six available multiplexes use this mode, with the other four multiplexes using the more robust but lower capacity 16-QAM encoding, introduced in the early days of DTT broadcasting when low power for digital was necessary to avoid co-channel interference with analogue transmissions.
