>Is it a fact that every television will have to be HD once the system is digital ?
Many people currently use a non-HD ready TV with digital by plugging a freeview box into the back of their TV.
Even when the analogue signal is switched off this set up will still work.
So even when ONLY digital is available you will still be able to watch Freeview by plugging a Freeview box into the back of a non-HD TV.
Note that Sky and Virgin are ALREADY DIGITAL and many people are happily watching them with a non-HD ready TV.
As someone has said digital and HD are NOT the same thing.
Digital can currently be picked up by a Freeview box, and this is NOT in HD.
