SYSTEM FOR TRANSMITTING A PACKETIZED MESSAGE, TRANSMITTER AND RECEIVER FOR USE IN SUCH A SYSTEM, AND METHODS OF TRANSMITTING AND RECEIVING A PACKETIZED MESSAGE

摘要

In a system for transmitting a message in a plurality of packets a similar identifier is assigned to each packet, in accordance with the invention, in order to identify packets having the same identifier as parts of the same message. This is of particular advantage in the Radio Data System, especially for the TMC multi-group messages. In this case the combination of Location code and Extent code can be used as such an identifier, which codes should then be repeated in each group of the multi-group message.
