Abstract
Methods and apparatus, including computer program products, implementing and using techniques for providing access for a networked device to a directory service for terrestrial broadcasts. A networked-based directory service that includes broadcasting data for one or more broadcasting stations within various geographical locations is provided. The broadcasting data includes tuning information that enables receivers to tune in one or more terrestrial broadcasts transmitted by the one or more broadcasting stations. A request is received from a networked device to obtain information about an availability of terrestrial broadcasts at a geographical location of the networked device. The directory service is queried using the geographical location as a query parameter. A response is transmitted to the networked device. The response includes tuning information that enables a receiver to automatically tune to one or more terrestrial broadcasts associated with the geographical location of the networked device.
