摘要

Developing innovative applications in the field of broadcasting can be challenging for several reasons. An increased democratization of broadcasting transmission equipment is highly desirable to foster the development of new services.rnThis paper presents the system integration of a full real-time Digital Audio Broadcasting (DAB) transmission chain that runs from a single live CD. A particular effort was done to reuse and combine the key building blocks required to build this system.rnFirst, system components needed to build the DAB transmission system are identified. On one hand, a generic PC, the Universal Software Radio Peripheral (USRP) and a generic G.703 network device are selected as the base hardware. On the other hand, GNU Radio and other software modules are used. Second, the integration method based on open source software is described. A customization tool is used to adapt a Ubuntu installable live CD.rnThe resulting disk image was tested on different platforms including desktops, laptops and virtual machines. The system worked on every tested platform that could also run the original base Ubuntu live CD. Joint use of the live CD, a USB key and a laptop proved to be a very convenient way to build portable and easy to use demonstration of the DAB technology.
