Broadcasting for the future

When television first started, the system of broadcasting was analogue. This meant that a TV aerial received radio waves from the TV companies. These transformed into sound and images on the TV screen. At the time, the system was revolutionary, but it wasn't perfect. It couldn't transmit many channels and the quality of the pictures was sometimes poor because of interference. For a long time there was only analogue TV, but at the end of the 1990s, digital television arrived.

Digital TV doesn't use radio waves. Instead, it converts sound and images into binary code. This is a computer language which only consists of zeros and ones and broadcasters can use it to send a lot of information very quickly. This digital information arrives at a TV via an aerial, a cable, a satellite dish, or broadband. Then a decoder converts the information back to sound and images. Decoders are either inside a TV or computer, or in a separate box which is connected to it.

Digital broadcasting is much better than the analogue system. There are a lot more channels because the TV companies can transmit much more information. The quality of the images and sound is much higher because there is less interference. Picture quality is even better on a high definition TV (an HDTV) than on a standard TV, so viewers can enjoy cinema-quality pictures in their own home.
