Edited by Martin Cave and Kiyoshi Nakamura

Digital television is transforming both broadcasting and, as a result of convergence, the larger world of communications.

It shows how this depends upon what platforms – cable, satellite, fixed or wireless broadband – countries have available for use and also upon government policies and regulatory interventions.
