Data transmission system for Xlet-based data words via bundle-based interface for digital audio and digital video radio broadcasts and with provision for receiving global positioning system signals

摘要

A receiver (12) is fed with a string of signals (10,11,11',13). The data signals (10) are demodulated, and Xlet-based data blocks (11,11') and MOT (Multimedia Object Transfer Protocol) signals (13) are sent onward to a data processor (14) containing a store module (15). The data processor may send and receive data (17) from several data sources (16) for global positioning system (GPS) navigation.
