Introduction
1 Motivation for DVB-H
Over the last ten years digital technology has encouraged a rapid growth in the personal consumption of media. The advent of personal video recorders (PVRs), video-on-demand and the multiplication of program offerings have enabled viewers to personalize the content that they want to watch. And with interactivity, viewers can directly express their preferences to broadcasters.
As part of this trend, and alongside the growth of mobile
