Abstract
Since the Eureka-147 DAB (Digital Audio Broadcasting) system was announced in the middle of 1990s, many kinds of applications have been introduced in many countries in the world as well as in Europe. T-DMB (Terrestrial Digital Multimedia Broadcasting), which is developed in Korea, is one of the applications which have emerged from Eureka-147 DAB system. T-DMB system provides mobile multimedia broadcasting services including moving pictures as well as CD quality digital audio services in the VHF band. This paper introduces the Korean T-DMB standard based on Eureka-147 DAB and proposes the architecture of a new T-DMB transmission system, which uses a new device called the Ensemble Remultiplexer, to verify it. Although the proposed T-DMB transmission system is the improved version of the conventional DAB system, it still utilizes the existing devices from the DAB system in many parts. Therefore, it provides a solution with high flexibility and low cost for mobile multimedia broadcasting services. We also verified the Korean T-DMB standard and evaluated the proposed T-DMB transmission system by moving the city surrounded by high buildings in high speed. The T-DMB is transmitted at the broadcasting station site in Kwanak mountain in Korea. From the result of this experiment, we could confirm that the T-DMB keeps good quality pictures without any problem comparing to analog broadcasting. The T-DMB is expected to provide mobile multimedia broadcasting services for users from the middle of 2005 and will be evolved to focus on more intelligent and interactive services in Korea.
