Digital television signals and technology have changed a lot recently to create many advantages for many people, such as editors and the audience. One of the main advantages is that it allows you to view a wider range of channels, which have better signal, as well as picture. However, many would also debate the idea that digital is better quality then analogue TV. Digital television has also expanded because it allows you to have features, such as TV on demand and interactive TV. This has also made it a lot more popular and appealing for the audience. Another advantage is that ability to compress footage onto a small device, for example an i-pod or phone. They way digital signals have changed has also improved how TV companies edit their videos and programmes. This is because they are able to do it more efficiently and add special effects etc. much more easily, whereas using a tape takes a lot longer and you have to do everything in 'real life' timings.
