The "digital revolution" of the last two decades has pervaded
innumerable aspects of our daily lives and changed our planet
irreversibly. The shift from analog to digital broadcasting has
facilitated a seemingly infinite variety of new
applications-audience interactivity being but one example. The
greater efficiency and compression of digital media have endowed
broadcasters with a "digital dividend" of spare transmission
capacity over and above the requirements of terrestrial
broadcasting. The question is, who will use it, and how? Comparing
the European experience with that of broadcasters elsewhere in the
world, the author sketches the current status of international
frequency management, quantifies the value of the "dividend"
itself, analyzes the details of the analog-to-digital switchovers
already completed, and posits what the future holds for the sector.
As we grapple with new devices, inconceivable a mere generation
ago, that allow us to access digital media instantly, anywhere and
at any time of day, this book is a potent reminder that what we
have witnessed so far may be just the first wavering steps along a
road whose destination we can only guess at.
