Digital switchover is completed in parts of the South
The final stage of the digital switch over is taking place in the South.
Television viewers in parts of West Sussex, Brighton, Hampshire, Wiltshire, Dorset and the Isle of Wight will lose their analogue channels on Wednesday.
The changes are the second phase of the Rowridge and Whitehawk switchover. The BBC Two signal was switched off in the first phase on 7 March.
Freeview, BT Vision and Top Up TV viewers using transmitters at Rowridge and Whitehawk will have to retune.
Households who have not switched to digital will lose their TV service.
The exact time of the switchover for each household will depend on which relay transmitter they are watching but the process, which began at midnight on Wednesday, is expected to be complete by late afternoon.
Rowridge viewers will also have to retune their equipment again on 18 April when further technical changes take effect.
