A method of transmitting digitally coded traffic information is described, in which a digitally coded traffic message including location information is transmitted is standard format, preferably according to the TMC method. When the location information in the traffic message requires change and/or completion, a header is provided in front of the traffic message, which indicates that additional information including changes or additions to the location information in the traffic message follows the traffic message. A receiver for reception and analysis of the digitally coded traffic information is also provided, which analyses the traffic information including the additional information to obtain the changed or completed location information.

Method of transmitting digitally coded traffic information and radio receiver for same

In a method of transmitting digitally encoded traffic messages, the traffic messages being transmitted according to a standardized structure, in particular according to the TMC method, where a header precedes the digitally encoded traffic messages, and the digitally encoded traffic message is followed by at least one additional item of information, and one of these items of information contains a place description, the additional information is divided into classes, each class having a class identifier and at least one packet. One class contains presentation data.

Method for transmitting digitally encoded traffic messages

A method for transmitting traffic announcements via Digital Audio Broadcasting (DAB), making use of the TMC code, where it is possible to have a simple allocation of the audio signals to the TMC data. In this context, the allocation is predetermined by the data frame of the digital transmitter and by the corresponding data protocol.

Process for transmitting messages by digital sound broadcasting and receiver for carrying out this process

A method of separating and identifying verbal announcements in a wireless transmission according to the GSM standard, in which verbal announcements from the audio stream can be associated with digital signals with the help of an ID number, so that the announcements can be separated.
