10. A system in a vehicle for receiving a broadcast data message from a remotely located information center, the broadcast data message comprising a message portion and a filter code section, the filter code section comprising coded criteria that specify characteristics of intended recipients of the message portion, comprising:
-
a receiver for receiving the broadcast data message, the receiver comprising a memory and a filter processing section that reads the filter code section of the broadcast data message to determine whether the vehicle is an intended recipient of the message portion, wherein the receiver stores the broadcast data message in the memory; wherein the filter processing section recovers the message portion of the broadcast data message stored in the memory, if the vehicle is an intended recipient, and discards the message portion, if the vehicle is not an intended recipient; and a display that receives and displays the recovered message portion from the memory in the receiver to a vehicle occupant. - View Dependent Claims (11, 12, 13)

14. A system in a vehicle for receiving a broadcast data message from a remotely located information center, the broadcast data message comprising a message portion, a filter code section, and a unique identifier, the filter code section comprising coded criteria that specify characteristics of intended recipients of the message portion, the system comprising:
-
a receiver for receiving the broadcast data message, the receiver comprising a filter processing section that reads the filter code section of the broadcast data message to determine whether the vehicle is an intended recipient of the message portion; wherein, if the receiver determines that the vehicle is not an intended recipient, the receiver discards the message portion; wherein, if the receiver determines that the vehicle is an intended recipient, the receiver recovers the message portion, stores the message portion into a memory storage medium, and stores the unique identifier into an identifier list; and wherein the recovered message portion is deleted from the memory storage medium in response to a delete command that is received by the receiver, the delete command being specific for the recovered message portion that is associated with the unique identifier. - View Dependent Claims (15, 16, 17, 18, 19, 20)
