Television is received through your aerial from a transmitter.
There are over 1,100 transmitters dotted around the country.
From 2008-2012, the transmitters will be switching over to digital - one by one...
Your television aerial is pointing at one of these transmitters.
That means your switchover date depends on the transmitter you are watching.
How many channels you receive and your signal strength will also depend on the transmitter.
Beams from nearby transmitters often overlap, so you may have a choice of transmitter to watch.
Changing from one transmitter to another may change the selection of channels you receive.
You usually point to the best one for you - however you may want to check.
If you need to change your transmitter, you'll need to contact a qualified installer and will need a new aerial.
So that's why transmitters do matter.
