1. OVERVIEW
a) What is Digital TV?
Digital TV has recently been introduced in the UK. Digital refers to the way
the transmission of images and sound that make up a TV programme are
transmitted to your TV set. Much in the way a computer works by coding
data in a stream of ones and zeros - digital TV sends a coded signal to
your TV set. This means that the airwaves taken up by digital TV take up a
lot less space. The airwaves that once transmitted one analogue channel
will now have space to transmit up to six or seven digital channels. As a
result the viewer has more choice. Widescreen TV is another option that
digital TV can provide.
Interactive TV is yet another feature of Digital TV. By using your remote
you can access all kinds of information. Digital text is much clearer than
the old analogue format. Digital systems allow you to choose your camera
view of big events using the interactive channels. With more and more fea-
tures such as these digital TV is paving the way for a much more interac-
tive experience when watching TV.
The Government has decided that some time between 2005 and 2010 the
analogue services will be switched off. They have however indicated that
the 'switch - off' will only happen if most viewers have decided to make the
switch to digital TV themselves.
b) Why is Digital TV Better?
Digital TV is better for a number of reasons.
One of the main reasons is that there will be more choice of what is avail-
able to view. With interactive TV becoming the way of the future, con-
sumers will have more of a say as to what standards are set in place in
regards to broadcasts.
The images and sound are clearer and widescreen TV is much easier to
access through Digital TV. As analogue TV is eventually going to be
switched off, resources into broadcasting will tend to be put into digital TV
and not the older analogue type transmissions (a method that has been
used for about 60 - 70 years). As a result if people want to know what is
new, be it features of digital TV or the types of shows that are being aired -
