Traffic Message Channel (TMC) is a technology for delivering traffic and travel information to motor vehicle drivers.

It is digitally coded using the ALERT C protocol into RDS Type 8A groups carried via conventional FM radio broadcasts. It can also be transmitted on Digital Audio Broadcasting or satellite radio. TMC allows silent delivery of dynamic information suitable for reproduction or display in the user's language without interrupting audio broadcast services. Both public and commercial services are operational in many countries. When data is integrated directly into a navigation system, traffic information can be used in the system's route calculation.

The ISO:14819 Module is a cost-effective solution to decode Traffic Message Channel (TMC) streams. With it's low memory consumption and high execution speed, it is suitable for Desktop applications, as well as Embedded systems.

ISO::14819 focuses on vendors who would like to integrate the module in their own commercial software products. Therefore the application programming interface was designed to give software developers fast access to the technology. This includes a compact but comprehensive source code documentation, and sample codes.

The module can be build with all major compilers under all major operating systems.
