This Handbook provides guidance to engineers responsible for the implementation of digital terrestrial television broadcasting and combines material dealing with digital and analogue television systems and planning aspects of this new topic.



Network planning

Throughout much of the World analogue television is highly developed, and most countries achieve more than 99% population coverage on at least two or three national networks. In parallel, a large number of local networks with lower coverage are operated. The need to achieve a large percentage of coverage leads to the use of very many television transmitters. The radiated power of these covers a wide range: from about 1 MW effective radiated power (e.r.p.) for major stations serving large areas, to less than 1 W e.r.p. for small stations intended to serve perhaps a few hundred people.
