Interactive data broadcasting services based on middleware technology in T-DMB

In this paper, we present the interactive data broadcasting service in T-DMB using middleware technology, which is known as T-DMB MATE (Mobile Application Terminal Environment). The T-DMB MATE defines a number of API to provide various applications with high-level functionalities for interactive data service, supporting a running environment of the applications. Specially, this paper introduces an implementation of T-DMB MATE receiver and some kinds of applications based on the designed T-DMB MATE service. Finally, the effectiveness of proposed service was verified by implementing the receiver and a variety of applications.

I. Introduction

Terrestrial Digital Multimedia Broadcasting (T-DMB) provides a mobile multimedia broadcasting services in good quality, based on the Eureka-147 DAB system [1]–[3]. In addition to the video standards including MPEG-4 technologies [4], T-DMB supports the various data transport protocol such as Multimedia Object Transfer (MOT), IP Tunneling, and Transparent Data Channel (TDC) [5] [6], which is specified by Eureka-147 DAB. T-DMB also accommodates the basic data services like Broadcasting Web Service (BWS), Slide-Show through these data transport protocols. In addition to these basic data services, T-DMB is ready to supply rich media services.
