Satellite is the first choice for digital TV
In the same way as CDs won over analogue vinyl records, and digital cameras succeeded film, so the conventional analogue television system that has been with us for over 60 years is now being replaced by digital TV. The quality, ease, cost and versatility of digital media has triumphed over analogue in all areas.
While the actual broadcast radio signals that carry digital TV are the same as those used for analogue, the picture and sound information is very different. An analogue TV picture is carried as a continuous waveform, but digital TV images are encoded as a stream of digital data.
This makes a digital TV signal very robust and resistant to the distortion and interference that plague analogue television, and so digital TV pictures and sound on your TV screen are top quality. If you use a modern digital display television (an LCD, DLP or plasma TV) as well, then you can be sure that the programmes you see are exactly as they left the TV studio.
The digital data can also be compressed in size so several TV channels can be carried in the same broadcasting space as a single analogue one, and additional data such as programme information, multiple soundtracks, and on-screen information can be broadcast.
Digital satellite TV means more channels for you to choose from, in better quality, with new services not possible from yesterday’s analogue television.
