DTT (digital terrestrial television) also known as Freeview
Digital terrestrial TV (DTT) in the UK is delivered free to air by Freeview. You receive Freeview via an aerial and you can get it on its own, from Youview or as part of a subscription package from BT Vision or TalkTalk.
Typical DTT reception problems include picture break-up (pixelation) or freezing, clicking sounds, sound dropping out and no reception at all. You may also find that interactive services (red button) aren't working, channels are missing, or you're receiving channels from the wrong region.
This can be caused by a number of things:
- Weak signal
- Too strong a signal or a signal from more than one transmitter
- Problems with your set top box or IDTV
- Weather related problems
- External interference
A DTT picture will begin to break up ("pixellation") and may freeze or vanish suddenly with weakening signal. The TV may even show a "no signal" message. This sudden effect is often called the digital cliff. No matter what type of interference or reception problem affects your digital signal, you are likely to see break up, freezing or lost pictures and sound.
A good aerial installation is vital in achieving reliable Freeview reception. For more information about aerials, visit this page.
