1. INTRODUCTION
1.1. About KVARTA
For more than 20 years, Kvarta has been developing products for Broadcasters and CATV providers.
Our devices are used by major radio and television broadcasters and regulatory agencies.
Broadcasting is our passion. We know what you want and we have designed many devices, which are
perfectly adapted to your needs. These include RDS encoders, FM Radio monitors and CATV systems.
KVARTA has a reputation for excellence and innovation among its clients and partners.
Our CATV, DVB Monitoring devices and RDS/RBDS encoders are growing in popularity due to their
reliability, quality and functionality at exceptional prices. All of our products have been designed for
professional broadcast use and are fully meet the standards. Our devices incorporate embedded web
site and SNMP communication.
1.2. About TMC
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.
Each traffic incident is binary-encoded and sent as a TMC message. Each message consists of an
event code, location code, expected incident duration, affected extent and other details.
1.3. About iTraffic
We created this server in order to help people get informed about any kind of traffic information at
all times. We can help monitor your existing traffic information broadcast (TMC) or help you create
your TMC broadcasting service. If you want to become our partner, please, contact us at
info@kvarta.net
The iTraffic server was initially created by Iliya Manev and Todor Manev. The name of the server
iTraffic comes from „Iliya Traffic“ in memory of Iliya Manev who is no longer among us.
We would like to thank Laszlo Heckenast for the extensive support he gave us in creating this server.
We would also like to thank Bence Makai and TrafficNav for the traffic information and support.

2. GENERAL INFORMATION
2.1. Graphical presentation of the TMC Monitoring Server
The RDS decoders receive RDS signals from an FM station and re-send it to the TMC server through
TCP/UDP protocol. The iTraffic server decodes the RDS signal – specifically the 3A and 8A groups
which are responsible for the traffic message channel (TMC). After that, the traffic messages are
stored in a database.
Traffic messages are decoded thanks to the Location tables and Alert C event descriptions (in TMC,
locations are pre-defined and pre-coded, and the codes are stored in location code tables)


Stored traffic events can be exported as XML files to an FTP server
Traffic events can be viewed on the server website iTrafficServer.com, displayed on a
versatile and user friendly traffic information map
www.kvarta.net

2.2. Graphical presentation of the TMC Broadcasting Server
Traffic events can be inputted as XML files to the broadcasting server from an FTP server. Traffic
information is stored in the broadcasting server database. The 8A and 3A groups for TMC are
encoded into UECP packets. Then, they are being sent to the RDS encoders using the TCP/UDP
transport protocol. The information is then broadcasted using radio FM transmitters to the end users
portable navigation devices (PND).
Note: iTraffic server supports TMC encryption
