Traffic Data over HD Broadcasts
Clear Channel will distribute traffic information to HD Radio receivers: The radio giant's head of distribution development said that they would launch this service into 48 markets, a close overlap to their current, much slower system. Initially, 100 stations will broadcast traffic data over HD Radio signals, although this will spread to all Clear Channel stations. An HD Radio traffic module will be necessary to receive the data and integrate it into navigation systems.
The exec expects this service to be built into cars by companies that offer navigation systems to automakers. This will allow automakers to add new information remotely, such as new stores that have opened since the GPS system was primed at the factory. An alternate system called RDS runs about 1/20th the speed of HD Radio, but is better designed for handhelds and after-market products due to price and power use.
