DANSK DS/EN ISO 14819-3 PDF

This standard primarily addresses the needs of RDS-TMC ALERT-C messages which arein widespread worldwide use , however, the modular approach used here is intended to facilitate future extension of the location referencing rules to other traffic and travel messaging systems. The location referencing rules defined in this part of ISO 14819 address the specific requirements of Traffic Message Channel (TMC) systems, which use abbreviated coding formats to provide TTI messages over mobile bearers (e.g. GMS, DAB) or via exchange protocols like DATEX and DATEX II. In particular, the rules address the Radio Data System – Traffic Message Channel (RDS-TMC), a means of providing digitally-coded traffic and travel information to travellers using a silent data channel (RDS) on FM radio stations, based on the ALERT-C protocol. A certification process is set in place within TISA to validate in detail the submitted location tables. This certification procedure extends the basic rules mentioned in this standard and also applies a best-practice validation. TISA grants a stamp of quality to those location tables that pass a set of tests.
