The new D3&4 mux is done by BT M&B www.mediaandbroadcast.bt.com
(NOT Arqiva) and if i was designing it I would feed it HD in any case - its simpler and gives better coding.
It uses Software encoders - as does PSB3 ....
Having been looking at (PSB) going T2/HD since 2008 there are many factors that come into play ....
How many T1 only viewers will you turn off ?
(on the other hand if the Digital Help Scheme surplus (£400M) was applied to this -it buyes a lot of basic STB
( but not so much now Basic is Freeview play)-the surplus just went into the consolidated fund)
How do you allocate the Muxes?
- at present all PSB muxes are regionalised - say 450+ coders
but the services carried can be done by a regional mux a national mux and a UK wide mux = say just 200 coders
Getting rid of SD simulcast and increasing bit rate by T2 gives almost an spare mux.... who will use it ?
as the contracts with Arqiva run to 2035 and amortise the cost of DSO over 25 years.
There are so many more .... it is amazing how what appear trivial matters can swing the direction of the design
But overarching is the political support - sadly the Vaizey plan did not get this .....
and the BBC /C4/Arqiva initative did not get public support either!
.... and Im retired!
