Digital TV (in UK)

[Ewood27]

Can somebody please un-confuse an OAP?  I have an ordinary TV with a roof aerial for the "terrestrial" channels.  I also have cable with a set-top box, through which I can receive the same terrestrial channels as well as all the others, on the same TV set.

 

When TV goes all-digital, will I simply have to take all channels through the set-top decoder, or will I need to buy something new?  Do so-called digital TVs just have a decoder built in?

when terrestrial tv is "switched off" scheduled for 5 years or so's time I believe, you will then have to rely on your set top box to pick up tv channels. Of course if you want to record one thing whilst watching another you will need another such unit, or at least a dvd or vcr with inbuilt digital decoder. New tv s will have this built in too - i think there are already sets on the market with this option

Thank you, romko.  Quick answer!  That's rather what I expected.  If only technology would stay still for a bit and let me catch up!
