• Bandwidth
• Broadcasters
• BT Vision

The amount that a digital channel can spread outside of its frequency. With digital, the greater the bandwidth, the faster the material can travel. This means that data such as the EPG (Electronic Programme Guide) or Teletext can appear on your screen faster, or picture and sound can be of a higher quality because the bandwidth can contain more information.
