The transition to Digital Television
ECON POLICY, 2005Co-Authors: M OttavianiAbstract:This paper studies the role of economic policy for the transition from analogue to Digital Television, with particular attention to the switch off of the analogue terrestrial signal. The analogue signal cannot be credibly switched off until almost all viewers have migrated to Digital, due to the policy objective of universal access to Television. But before switch off, only part of the population can be reached with the Digital signal. In. addition, those who are reached need to spend more to upgrade their reception equipment than after switch off, because the capacity to increase the power of the Digital signal will be made available only then.After reviewing the competitive structure and the role of government intervention. on in Television markets, we present the early experience of a number of industrialized countries in the transition to Digital Television. We then formulate a micro-econometric model of Digital Television adoption by individual viewers. The model is calibrated to UK data and simulated to predict the impact of government policies on the take-up of Digital Television. Policy makers can affect the speed of take up of Digital Television by: (1) controlling the quality of the signals and the content Of public service broadcasters; (2) intervening in the market for Digital equipment with subsidies; and (3) publicizing the conditions and date Of switch off of the analogue signal. We find that if the analogue terrestrial signal is switched off only when certain aggregate adoption targets are reached, strategic delays may arise and expectations may affect. the success of the switch off policy.

Technology and standards of Digital Television terrestrial multimedia broadcasting
IEEE Communications Magazine, 2010Co-Authors: Chung Yen Ong, Changyong Pan, Jian Song, Yangang LiAbstract:The Digital Television terrestrial multimedia broadcasting standard was ratified on August 18, 2006, and is the mandatory Digital Television terrestrial broadcasting standard in China. DTMB defines the signal frame structure, the coding and modulation schemes, and adopts timedomain synchronous orthogonal frequency-division multiplexing technology using pseudo random sequence as both the guard interval of the OFDM block and the training symbol. It can deliver fast system synchronization, accurate channel estimation, high spectrum efficiency, and excellent single-frequency network performance. This article covers the major features of the DTMB standard, its industrialization, current deployment status, and various applications based on the DTMB standard. © 2010 IEEE.
