The Prototyping Methodology of a Data Receiver for Digital Audio Broadcasting (DAB) Networks

In this paper we describe the implementation methodology of a prototype for reception of IP datagrams transmitted over digital audio broadcasting (DAB) networks. The system reads the DAB ensemble from the RDI output of a DAB receiver, extracts the IP datagrams and feeds them to a personal computer via an USB port. We have implemented the system on an FPGA with an embedded RISC processor. We also describe the tools whose development was needed to ease the IP extractor development and to test the functionality of the system. Finally the results of our tests with two applications of IP data transmission over DAB networks, data carousels and video streaming, are presented
