System for broadcasting local information, related to the area where a vehicle (V), e.g. an automobile, is actually located or moving through, having: a GPS (1) that identifies the area where the vehicle is moving through, a GPRS transmission means (2) for transmitting the said local information from an external, remote station to a CPU (3) located in the vehicle and for managing the information related to the data from the positioning system and the local information. The system has a storage device (4, 5) for the local information, located within the vehicle, and an FM broadcasting device (6), also located within the vehicle, adapted to broadcast the said local information to a reproducing means (7), that can be the radio system of an automobile. The said local information is selected from the stored information in the storage device (4, 5), according at least to the identified area and is updated, on a time basis, with local information emitted from an external updating emitter. As the local information is updated on the information means on a time basis (not necessarily periodically), the system allows obviating the need for 1) streaming information in a continuous manner; and 2) having a whole network at disposal, which prejudices the efficiency and the perceived quality of the service. |

1. A system for accessing and providing local information to a user relating to an area where a vehicle is actually located or moving through, the system comprising first and second groups of components, wherein:
A. the first group of components is located inside the vehicle and comprises:
a receiver configured to receive local information from an emitter;a storage device configured to store local information received from the emitter about where the vehicle is located, wherein the local information is updated on a recurrent time basis with local information received from the emitter;a GPS positioning system configured to identify the current geographic area where the vehicle is located or moving through;a processor configured to:
manage data being processed;select local information from the storage device relating to the current geographic area where the user is moving through;determine, in terms of the speed of the vehicle and a map of GPS coordinates, the location of the subsequent geographic area and the remaining time to enter the subsequent geographic area; andswitch local information in the storage device relating to the current geographic area to local information relating to a subsequent geographic area that has different information to be transmitted to the user, as a function of the determined location of the subsequent geographic area and the remaining time to enter the subsequent geographic area; anda broadcasting device which receives a signal comprising selected local information from the processor and transmits the signal to a reproducing device as an audio signal; and B. the second group of components is located externally to the vehicle and comprises:
a server which is in communications with the processor and which selects local information that is to be transmitted to the receiver; andthe emitter which communicates with the server and which transfers to the receiver packs of local information codified and classified according to X, Y, Z GPS coordinates. |
