Abstract

Overview

Written by industry expert Saulle Mattei, this report evaluates technologies and solutions currently available for mobile TV implementation and operation. This publication is intended to assist with decisions concerning selection, implementation, and operation of a mobile TV system. Mr. Mattei discusses standards impacting mobile TV, evaluates mobile TV trials to date, and discusses components required and issues associated with deploying mobile TV. He also provides a technology comparison, weighing the pro' s and con' s of each technology. The report also includes information about some mobile TV trial results and a view of the future for mobile TV.
