Abstract

System, methods, and apparatus are provided for wireless vehicle-to-vehicle sharing of multimedia data. The system includes a data storage device configured to store multimedia data packets transmitted by a system broadcast, a processor coupled to the data storage device and configured to determine a non-received group of multimedia data packets based on the stored multimedia data packets of the system broadcast, and a transceiver coupled to the processor. The transceiver is configured to receive multimedia data packets transmitted from the system broadcast and multimedia data packets transmitted from a system vehicle in response to the request signal. The method includes the steps of determining non-received multimedia data packets based on a system broadcast in a first wireless protocol, and requesting multimedia data packets of the non-received multimedia data packets in a second wireless protocol from system vehicles.

4. A multimedia system according to claim 2, wherein said transceiver is further configured to receive a request signal transmitted from said system vehicle;

and

wherein said processor is further configured to determine available multimedia data packets based on said stored multimedia data packets for transmission in response to said request signal received from said system vehicle.

5. A multimedia system according to claim 4, wherein said transceiver is further configured to:

wirelessly receive in a first wireless protocol said multimedia data packets of said system broadcast; and

wirelessly receive in a second wireless protocol said multimedia data packets of said system vehicle and said request signal transmitted from said system vehicle.

6. A multimedia system according to claim 5, wherein said transceiver further configured to wirelessly transmit in said second wireless protocol said request signal for multimedia data packets of said non-received group of multimedia data packets.

7. A multimedia system according to claim 1 further comprising:

a decoder coupled to said data storage device, said decoder configured to;

access said multimedia data packets stored in said data storage device;

associate each of said multimedia data packets stored in said data storage device with a multimedia data file; and

assemble said multimedia data file upon receiving a threshold number of multimedia data packets, said data storage device configured to store said assembled multimedia data file.

8. A wireless network apparatus for vehicles, said apparatus comprising:

a vehicle receiver configured to receive multimedia data packets transmitted from a system broadcast;

a data storage device coupled to said vehicle receiver, said data storage device configured to store said multimedia data packets received by said vehicle receiver;

a processor coupled to said data storage device, said processor configured to identify multimedia data packets stored in said data storage device with a multimedia file and determine a non-received group of multimedia data packets and a received group of multimedia data packets based on said multimedia data packets stored in said data storage device;

a transceiver coupled to said processor, said transceiver configured to;

receive multimedia data packets transmitted from a system vehicle and a request signal transmitted from said system vehicle; and

transmit at least one signal selected from a signal requesting multimedia data packets of said non-received group of multimedia data packets, a status signal indicating said received group of multimedia data packets, and a group of multimedia data packets in response to said request signal transmitted by said system vehicle, said data storage device further configured to store said multimedia data packets received by said transceiver.

9. A wireless network apparatus according to claim 8, wherein said processor is configured to determine said non-received group of multimedia data packets and said received group of multimedia data packets based on said multimedia data packets received by said vehicle receiver and said multimedia data packets received by said transceiver.

10. A wireless network apparatus according to claim 9, wherein said vehicle receiver is configured to receive multimedia data packets in a first wireless protocol within a first operating range;

and

wherein said transceiver is configured to receive multimedia data packets in a second wireless protocol within a second operating range, said first operating range greater than said second operating range.

11. A wireless network apparatus according to claim 8, wherein said processor is further configured to assemble said multimedia data file upon receiving a threshold number of multimedia data packets, said data storage device configured to store said assembled multimedia data file.

12. A wireless network apparatus according to claim 11 further comprising a playback device coupled to said data storage device, said playback device configured to read said assembled multimedia data file.
