Abstract

Apparatus is provided for an electronic vehicle storage system. The apparatus includes a data storage device configured to store multimedia files, a wireless transceiver configured to transfer multimedia files, and a controller coupled to the wireless transceiver, data storage device, and a vehicle electrical infrastructure. The data storage device has an embedded database containing a first list of multimedia files. The controller is configured to communicate with an external computing device via the wireless transceiver. The external computing device has a second list of multimedia files. The controller is further configured to synchronize the first list of multimedia files with the second list of multimedia files.

Claims

1. An electronic vehicle storage system for a vehicle having an engine and an available power supply, said electronic vehicle storage system comprising:

a data storage device configured to store multimedia files, said data storage device comprising an embedded database containing a first list of said multimedia files;

a wireless transceiver configured to transfer said multimedia files; and

a controller coupled to said wireless transceiver, said data storage device, and a vehicle electrical infrastructure, said controller configured to;

communicate with an external computing device via said wireless transceiver, said external computing device comprising a second list of multimedia files;

synchronize said first list of said multimedia files with said second list of said multimedia files, wherein said synchronization comprises transferring said multimedia files listed on said second list of said multimedia files but not on said first list of said multimedia files from said external computing device to said data storage device via said wireless transceiver, wherein said controller is further configured to synchronize said first list of said multimedia files with said second list of said multimedia files for a pre-determined synchronization time budget that is determined by said controller based upon said available power supply, and to stop synchronization after a pre-determined period of synchronization time has elapsed; and

adjust said pre-determined synchronization time budget by increasing said pre-determined period of said synchronization time while said engine of said vehicle is running and by decreasing said pre-determined period of said synchronization time as time passes while said engine is not running and as said synchronization occurs.

2. The electronic vehicle storage system according to claim 1, wherein said data storage device is a hard disk drive;

and

wherein said multimedia files are compressed digital multimedia files.

3. The electronic vehicle storage system according to claim 1, wherein said controller is further configured to:

detect a synchronization initiation signal via said vehicle electrical infrastructure prior to said synchronization of said first list of said multimedia files with said second list of said multimedia files.

4. The electronic vehicle storage system according to claim 3, further comprising a radio frequency (RF) receiver coupled to said vehicle electrical infrastructure;

and

wherein said synchronization initiation signal is a key fob signal received by said RF receiver.

5. The electronic vehicle storage system according to claim 1, further comprising a telematics transceiver coupled to said controller;

wherein said embedded database further comprises a list of multimedia file content corresponding to said first list of said multimedia files;

wherein said controller is further configured to associate a recognized multimedia file with a multimedia file content from said list of said multimedia file content; and

wherein said telematics transceiver is configured to retrieve said multimedia file content corresponding to a non-recognized multimedia file.

6. The electronic vehicle storage system according to claim 5, further comprising a satellite receiver coupled to said data storage device, said satellite receiver configured to receive an updated list of multimedia file content, said data storage device further configured to store said updated list of said multimedia file content.

7. The electronic vehicle storage system according to claim 1, further comprising a media playback device coupled to said controller, said media playback device configured to transfer said multimedia files to said data storage device via said controller, said media playback device selected from a compact disc player, a magnetic tape player, a compressed digital audio player, a mini-disc player, and a digital video disc player.

8. The electronic vehicle storage system according to claim 1, wherein said external computing device is a personal computer having a memory configured to store said second list of said multimedia files.

9. The electronic vehicle storage system according to claim 1, wherein said controller is further configured to determine said pre-determined synchronization time budget based on an amount of said available power supply that provides sufficient power for a vehicle start.

10. The electronic vehicle storage system according to claim 9, further comprising a battery power management system, and wherein said controller is further configured to communicate with said battery power management system and to determine said available power supply based on said battery power management system.

11. An electronic vehicle storage system for a vehicle having an engine operating in conjunction with a vehicle electrical infrastructure having a battery, said electronic vehicle storage system comprising:

a radio frequency (RF) receiver configured to provide a synchronization initiation signal in response to a signal received from a key fob;

a data storage device configured to store multimedia files, said data storage device comprising an embedded database containing a first list of said multimedia files;

a battery power management system coupled to said battery;

a wireless transceiver configured to transfer said multimedia files; and

a controller coupled to said wireless transceiver, said data storage device, and said vehicle electrical infrastructure, said controller configured;

to detect said synchronization initiation signal via said RF receiver;

to communicate with an external computing device via said wireless transceiver in response to said synchronization initiation signal, said external computing device comprising a second list of said multimedia files;

to communicate with said battery power management system to determine an available power supply;

to determine a synchronization time budget based upon said determined available power supply;

to synchronize said first list of said multimedia files with said second list of said multimedia files according to said determined synchronization time budget via said wireless transceiver;

to adjust said determined synchronization time budget by increasing said determined synchronization time budget while said engine of said vehicle is running and by decreasing said determined synchronization time budget as time passes during said synchronization while said engine is not running; and

to stop said synchronization when said determined synchronization time budget is expended.

12. The electronic vehicle storage system of claim 11, wherein said synchronization comprises transferring said multimedia files listed on said second list of said multimedia files but not on said first list of said multimedia files from said external computing device to said data storage device.

13. A method of operating an electronic vehicle storage system operating in conjunction with a vehicle electrical infrastructure providing an available power supply to a vehicle having an engine, wherein said electronic vehicle storage system comprises a wireless transceiver and a data storage device configured to store multimedia files and having an embedded database containing a first list of said multimedia files, said method comprising the steps of:

communicating with an external computing device via said wireless transceiver, said external computing device comprising a second list of said multimedia files;

determining a synchronization time budget based upon said available power supply and an amount of power needed to start said vehicle;

increasing said determined synchronization time budget while said engine of said vehicle is running;

synchronizing said first list of said multimedia files with said second list of said multimedia files based upon said determined synchronization time budget, wherein said synchronization comprises transferring said multimedia files listed on said second list of said multimedia files but not on said first list of said multimedia files from said external computing device to said data storage device via said wireless transceiver;
