Design and implementation of a multimedia content delivery system for portable devices

ABSTRACT

This paper describes the design of a multimedia contents delivery system able of offering TV, radio, podcast and file services to portable devices. These services are distributed using reliable multicast, specifically FLUTE protocol (File Delivery over Unidirectional Transport). An alternative mechanism for transmitting TV contents is also proposed in this paper. This mechanism is based in podcast and seeks to take advantage of the mobile broadcasting networks currently in development. In addition, an Electronic Service Guide (ESG) has been designed to inform the users about the available contents. Such ESG allows client applications to personalize contents according to user's tastes and interests. The paper is structured as follows: first, it provides an introduction about mobile television; second, it explains briefly key aspects for the reliable multicast transport and mobile broadcasting technologies; then, our system design is exposed and finally, the system implementation is described.
