High definition (HD) services have been available in the USA, Canada, Japan, South Korea and Australia for a number of years, with varying degrees of success. Broadcasters in Europe are now starting to launch HD services. This paper explores why and how they are doing so; some of the challenges they face; and whether or when HD will become a mass market service within Europe. It then assesses the applicability of European experience for broadcasters in the Far East and reviews the approaches, issues and costs that they should consider when building HD facilities and offering HD services. The focus of the paper is on HD transmission, but production issues are also explored.

involved and how this industry operates”.....
As broadcasters migrate to digital technology, the released analogue spectrum will provide plenty of options for re-use; but how can RF systems be made future-proof to accommodate the new services?

More and more companies are using Internet Protocol (IP) to transmit video over the network. However, while there are many advantages to using IP, there are also significant problems.
