This video (from the USA) informed me that you don't have to buy a new TV for the digital switch over, but you can buy a converter (like the RCA DTA 800) which will allow ur analogue TV to pick up digital signals. The video also informed me that this switch over takes place midnight Feb 17th 2009, but i believe this is just the case in the USA.

- Switch to all digital transmition means that the analogue specturum is free to those who really need it e.g emergency services.
- Cable/satellite viewers are not likely to be affected. However, those without this service may need to make some changes.
- You can receive more free channels, higher quality viewing experience and high definition programming if you choose.
- Analogue system: television signal is received through magnetic waves which can repeat and interfere with eachother, causing poor picture quality like ghosting, colour shifts and lines across the screen
- Digital systems: signal sent as 1s and 0s reducing problems with quality and allows broadcasters to send more info to your TV. In general...Digital TV sounds and looks better than analogue.
