News:
Congratulations to all those involved in the UK's digital switchover. The analogue television services from Crystal Palace were switched off on the morning of 18//4/12 and there is a newspaper article about it here. The huge and complex switchover project has been a great success and it demonstrates the fine abilities and dedication of many people.
The switchover project is very impressive, but the technology on which it is based is even more astounding. This web site covers the period up to 1997 and in most of that time it was almost unbelievable that so many television services could be broadcast within the radio spectrum that is now being used. It became possible as a result of brilliant people developing very effective digital video compression systems (MPEG) and efficient radio systems (OFDM). Also of course, these processes could only be implemented as a result of advances in micro-electronics.
Hopefully this good-news story will inspire more young people to become engineers!
The digital switchover celebratory light show at Crystal Palace somewhat trivialises the DSO achievement, but there are some good pictures of it here. The name Arqiva is on the tower because this is the company that fairly recently became the owner. The tower was built by BICC in 1955, under contract from the BBC's Engineering Division.
