An Analyzer of the User Event for Interactive DMB

The interactive digital multimedia broadcasting stands for a convergence application between digital multimedia broadcasting service and wireless internet service. It develops MPEG-4 BIFS (Binary Format for Scene) technologies which is standard component of associated data service for DMB. In this paper, we propose system architecture of the interactive DMB, called the interaction manager. The interactive DMB facilitates to transmit interactive contents and user can easily use these contents by clicking or typing some additional information. The proposed interactive DMB system can capture and response user interaction information by using the return channel. In this paper, we are mainly focused on extracting the event data of the user interaction on the device. We suggest an analyzer to catch the user event and transform into a specific format for bidirectional DMB service system.
