METHOD OF DISSEMINATING VALUE-ADDED INFORMATION

摘要

The method involves transmission of a message on one or more frequencies with an address code identifying a particular receiver. Another address code is assigned to each group or topic of value-added information which can be selected and accepted simultaneously by several receivers. The address codes for each utilised frequency together form a pool which in principle is available to each user of the service and includes a reference master address code. Channels are assigned which correspond to particular address codes within the pool, determinable from the reference code and the appropriate offset in each instance.
