DIGITAL RADIO AS AN ADAPTIVE SEARCH ENGINE Verbal Communication with a Digital Audio Broadcasting Receiver

摘要

This contribution presents the fundamentals for the design and realization of an improved digital broadcast receiver. The concept is characterized on the one hand by a content repository, which automatically stores spoken content elements. On the other hand a speech-based and a graphical interface are implemented, which enable users to directly search for audio and data content. For that purpose a DAB/DMB receiver is augmented to simultaneously monitor a variety of information sources. Other digital communication methods such as Satellite and HD RadiosTM or DVB are applicable as well. Besides broadcast receivers, the system can be integrated into next-generation mobile devices, such as cell phones, PDAs and sophisticated car radios. Priority is given to the idea of establishing a compact embedded solution for a new type of receiver, promoting the convergence of service offers familiar to users from the internet into the broadcast environment.
