Abstract
following a period of time of careful reflection. Now, the next generation of digital broadcast services will not be limited to digital audio but also extended to a variety of multimedia data services as well as mobile application services. However, the current approaches for transporting multimedia content over wireless networks for the DMB require significant overhead. In this paper, we propose a new approach for multi-user data multiplexing with several access points serving a number of wireless terminals for the DMB. By modifying the multiplexer header, multiplexing time, and handling of time-critical data, the duplication overhead can be considerably decreased when compared to existing schemes.
