A test of HD Radio conditional access traffic data services in Chicago has concluded successfully, according to organizers.
The results were first reported on RW’s “The Leslie Report” earlier this month. The companies have now issued a press release announcing the same.
Broadcast Electronics, Emmis Communications and NDS conducted the project, with involvement from Ibiquity Digital Corp. Testing was at Emmis station WKQX(FM).
“Pilot testing occurred May 23 and 24 and was the first conditional-access test for broadcasting real-time traffic information over the HD Radio system to vehicle navigational systems,” BE stated.
Initial testing addressed the ability of broadcasters to allocate bandwidth and protect content for mobile delivery of traffic information, it said.
BE and NDS, a conditional access technology supplier, provided an HD Radio system including NDS encryption and bandwidth provisioning by BE’s IDi 20 HD Radio importer unit.
The test involved maps and real-time traffic content and included authorization and de-authorization of the receiver for the data service, testing of system functionality, reception/decryption of traffic data at the receiver and recording and logging of data to determine latency and data stability in the encrypted channel.
“Test drives in various multipath environments around the Chicago area showed no dropped data packets or loss of service,” BE reported.
