Abstract
The invention relates generally to a digital broadcast system and receivers therein which are configured to allow the use of a reverse channel for transmitting responses to broadcast messages. The digital broadcast system is configured to receive requests for information from a mobile platform device (e.g., a GPS receiver) and broadcast information request messages. The receivers are configured to receive a broadcast information request message and communicate with a telematics-enabled device in a mobile platform such as a cellular telephone to initiate a transmission of a response message therefrom.
