This week sees the first stage of the
digital television switchover for 4,853,500 homes in Greater London.
From 6am Wednesday 4th April 2012, you must perform a "first time installation" retune (sometimes "Factory Reset" or "Shipping Condition") on your Freeview box or television set if you use the Crystal Palace, Hemel Hempstead, Reigate or Guildford full service Freeview transmitters.
This is because the old low power " multiplex 1" BBC service will be replaced by the high power BBCA multiplex on the old analogue BBC TWO frequency. Also, ITV 1 analogue will move to the BBC TWO analogue slot, except at Hemel Hempstead.
Crystal Palace (starts midnight, ends by 6am) - BBC TWO analogue closes on C33, ITV 1 analogue moves to C23 from C33, Multiplex 1 closes on C25-, Multiplex BBCA starts on C23.
Guildford (starts midnight, ends by 6am) - BBC TWO analogue closes on C46, ITV 1 analogue moves to C46 from C43, Multiplex 1 closes on C49-, Multiplex BBCA starts on C43.
Hemel Hempstead (starts midnight, ends by 6am) - BBC TWO analogue closes on C44, Multiplex 1 closes on C48+, Multiplex BBCA starts on C44.
Reigate (starts midnight, ends by 6am) - BBC TWO analogue closes on C63, ITV 1 analogue moves to C63 from C60, Multiplex 1 closes on C31, Multiplex BBCA starts on C60.
