Abstract

Systems and methods are provided for a multimedia storage and transfer. The system includes a first data storage device in a first vehicle, a wireless transceiver configured to communicate with a second data storage device in a second vehicle, and a controller coupled to the wireless transceiver and first data storage device. The first data storage device has an embedded database configured to store multimedia files. The embedded database has a list of multimedia file content. The controller is configured to remove the list of multimedia file content from the first data storage device and transfer the list of multimedia file content to the second data storage device via the wireless transceiver.

Claims

1. A multimedia storage and transfer system for a vehicle, said system comprising:

a first data storage device in a first vehicle, said first data storage device comprising an embedded database configured to store multimedia files, said embedded database comprising a first list of multimedia file content;

a wireless transceiver configured to communicate with a second data storage device in a second vehicle; and

a controller coupled to said wireless transceiver and said first data storage device, said controller configured to;

remove said first list of multimedia file content from said first data storage device; and

transfer said first list of multimedia file content to said second data storage device via said wireless transceiver.

2. A multimedia storage and transfer system according to claim 1, wherein said first data storage device is a hard disk drive having a memory;

and where said multimedia files are digital compressed multimedia files.

3. A multimedia storage and transfer system according to claim 1 further comprising a telematics transceiver coupled to said controller;

and

wherein said controller is further configured to associate a recognized multimedia file from said embedded data base with a multimedia file content from said list of multimedia file content, said telematics transceiver configured to retrieve multimedia file content corresponding to a non-recognized multimedia file.

4. A multimedia storage and transfer system according to claim 1 further comprising a media playback device coupled to said controller, said media playback device configured to retrieve multimedia files from a storage medium, said controller further configured to transfer said retrieved multimedia files from said media playback device to said embedded database of said first data storage device.

5. A multimedia storage and transfer system according to claim 4, wherein said media playback device is selected from a compact disc (CD) player, a magnetic tape player, a compressed digital audio player, a mini-disc player, and a digital video disc (DVD) player.

6. A multimedia storage and transfer system according to claim 1 further comprising a satellite receiver coupled to said controller, said satellite receiver configured to receive a second list of multimedia file content, said controller further configured to update said first list of multimedia file content with said second list of multimedia file content in said first data storage device.

7. An infotainment system for a motor vehicle, said infotainment system comprising:

a hard drive of a first vehicle, said hard drive comprising an embedded database configured to store multimedia files, said embedded database comprising a list of multimedia file content;

a wireless transceiver configured to communicate with a data storage device of a second vehicle;

an encryption unit comprising an encoder configured to encode digital rights management (DRM) protected multimedia files; and

a controller coupled to said hard drive, said wireless transceiver, and said encryption unit, said controller configured to;

remove said list of multimedia content from said hard drive; and

transfer said list of multimedia content to said data storage device of said second vehicle.

8. A multimedia storage and transfer system according to claim 7 further comprising a media playback device configured to retrieve multimedia files stored on a portable storage medium;

and

wherein said controller is further configured to transfer said retrieved multimedia files of said media playback device to said hard drive, said hard drive further configured to store said retrieved multimedia files of said media playback device in said embedded database.

9. A multimedia storage and transfer system according to claim 8, wherein said encoder is further configured to encode said multimedia files stored on said embedded database with a public key, said public key associated with said first vehicle.

10. A multimedia storage and transfer system according to claim 9, wherein said first vehicle has a vehicle identification number (VIN);

and wherein said public key is based on said VIN.

11. A multimedia storage and transfer system according to claim 9, wherein said controller is further configured to:

transmit said public key via said wireless transceiver to said second vehicle with said list of multimedia file content; and

remove said public key from said first vehicle.

12. A multimedia storage and transfer system according to claim 9, further comprising a digital media write device coupled to said controller;

and

wherein said controller is further configured to transfer public key encoded multimedia files stored on said embedded database to said digital media write device, said digital media write device configured to transfer said public key encoded multimedia files to a data storage medium.

13. A multimedia storage and transfer system according to claim 12, wherein said data storage medium is selected from a CD, a DVD, a mini-disc, an optical disc, a magnetic tape, and a floppy disk.

14. A multimedia storage and transfer system according to claim 9 further comprising a portable data storage device interface coupled to said controller.

15. A multimedia storage and transfer system according to claim 14, wherein said data storage device interface is a universal serial bus (USB) connection;

and wherein said controller is further configured to transfer public key encoded multimedia files from said embedded database to a portable data storage device via said USB connection.

16. A multimedia storage and transfer system according to claim 8, wherein said media playback device is selected from a CD player, a magnetic tape player, a compressed digital audio player, a mini-disc player, and a DVD player.

17. In a motor vehicle having a database of multimedia files, a method for transferring multimedia content, said method comprising the steps of:

identifying DRM protected multimedia files in an embedded database of a first vehicle;

transferring multimedia files from the embedded database to a second vehicle; and

removing the DRM protected multimedia files and DRM playback rights associated with the DRM protected multimedia files from the first vehicle.

18. A method for transferring multimedia content according to claim 17 further comprising the steps of:

determining multimedia files requiring DRM protection in the embedded database of the first vehicle; and

encrypting multimedia files in the embedded data base with a public key associated with the first vehicle.

19. A method for transferring multimedia content according to claim 18 further comprising the step of transferring the public key to the second vehicle;

and

wherein said DRM playback right removing step comprises the steps of;

transferring the public key to the second vehicle; and

removing the public key from the first vehicle.

20. A method for transferring multimedia content according to claim 17, wherein said transferring step comprises wirelessly transferring the multimedia files to the second vehicle.
