    摘要： An in-vehicle communication system (10) configured to receive signals (16) from a transmitter (18) configured to transmit periodically a time-reference signal (24) and receiver specific information (26). An information transmission time (28) of receiver specific information (26) is timed relative to a reference transmission time (30) of the time-reference signal (24). The system (10) includes a receiver (12) characterized as having a receiver identification value. The receiver (12) is configured to operate from an off-state to an on-state during an information-expected time interval (34) to receive receiver specific information (26). The information-expected time interval (34) is determined based on a reception time (36) of the time-reference signal (24) and the receiver identification value. This provides a way to ensure that the transmitter (18) only transmits messages when it knows the intended receiver (12) is on. It also ensures that the receiver (12) is on only when messages that for that receiver (12) are expected to be received.

    摘要： The invention provides systems and methods for targeting broadcast messages to particular vehicles or classes of vehicles. In one embodiment, the system comprises an information center for creating and sending a broadcast data message, and a relay section that receives the broadcast data message and relays the message to a plurality of vehicles. The information center typically comprises a one-to-many communication system for sending the message from one source to a plurality of receivers, such as a satellite radio network or the like. The message can be deleted or modified in response to commands received by the receiver.
