Help receiving television

Digital means that TV pictures and sound are converted into computerised 'bits' of information and compressed before being transmitted. The signal arrives at your TV set via an aerial, satellite dish, cable or broadband internet connection. It is then converted back into pictures and sound by a receiver (decoder), which is either in a set-top box connected to the TV or built into a digital TV.
