TV viewing is evolving from a lean-back to a lean-forward activity. The new TV services offer a higher degree of user participation than traditional TV viewing which is expected to influence users attitude towards TV and attract new subscribers. Future TV systems are expected to support any time, any place, any device consumption of a wide variety of services and content. Traditionally, Digital TV (DTV) operators have used digital video broadcast technology (DVB for cable, satellite and terrestrial systems) to offer free and pay-TV services. Deregulation of the telecom market has spurred telecom operators to enter the media business by providing TV over Internet Protocol (IP) networks.
