DVB-T2: A Broadcast Medium for Cooperative Systems

One of the key aspects in the field of Cooperative Systems – at least from the point of view of a motorway operator – is the availability of reliable, cost-effective communication media to get your services and traffic messages “I2V”, from the Infrastructure to the Vehicle. ASFINAG, the Austrian motorway operator, together with “Hitradio O3”, Austria’s largest radio station and ORS, the Austrian Broadcasting Service provider, therefore tested terrestrial digital video broadcast (DVB-T2) as a (broadcast) carrier medium for multimedia enhanced cooperative services and traffic messages. These tests were based on previous work on Cooperative Systems, namely the system architecture and TPEG services of the “COOPERS” project, which were enhanced by adding multimedia information (camera pictures and spoken audio messages) to the individual TPEG traffic service messages. The target area for the tests was the Vienna region with the high-traffic triangle of the A23, A4 and S1 motorways. Test results showed that in spite of strong DVB-T2 coverage and signal strength, message reception beyond a speed of 25km/h was not possible with currently available DVB-T2 receiver technology. DVB-T2 in its present state therefore is not a suitable broadcast medium for Cooperative Services, although this could change when more advanced receivers are commercially available.
