Understanding Digital Television

With the milestones of Digital TV and HDTV, there are
lots of questions to be asked about television of today...
Understanding Digital Television explains complex technical systems and solutions in an easy
to comprehend manner along with visual 3D graphics. It helps non-technical individuals such as
managers, executives, general media professionals, as well as TV and home cinema enthusiasts
gain a practical understanding of the equipment, technical aspects of digital television, and various
ways of distributing. Most examples are from a European perspective, but also include comparisons
with North American systems. This book answers the confusing questions about new devices and
digital formats, what to do when the analog TV transmitters are switched off, watching TV using your
broadband connection, and much more.
*Describes the four major platforms of digital TV: satellite, cable, terrestrial transmitters
and broadband
*Uses an extensive collection of illustrations to explain the technical solutions
*Includes detailed illustrations and full-color section
*Contains an appendices dedicated to North American systems
