Abstract

A control system in a vehicle for extracting meta data from a digital media storage device over a communication link. The system includes a communication module for establishing a communication link with the digital media storage device. The system also includes a processing module coupled to the communication module. The processing module is configured to retrieve, via the communication module, meta data associated with a media file from the digital media storage device. The meta data includes a plurality of entries, wherein at least one of the plurality of entries includes text data. The processing module is also configured to compare the text data of the entries with a set of data files stored in a database. The system also includes a memory module configured to store the plurality of entries retrieved from the digital media storage device.

Claims

1. A method for extracting meta data from a digital media storage device in a vehicle over a communication link between a control module of the vehicle and the digital media storage device, the method comprising:

retrieving, at the control module of the vehicle, meta data associated with a media file from the digital media storage device, the meta data comprising text data;

comparing the text data with a plurality of stored data entries;

if the text data matches a stored data entry, providing a phonemic representation for the text data based on a pre-stored phonemic representation associated with the stored data entry.

2. The method according to claim 1, wherein if the text data does not match at least one of the stored data entries, providing a phonemic representation for the text data based on the text data.

3. A method according to claim 1, further comprising storing the meta data in a memory.

4. A method according to claim 1, wherein the meta data are retrieved in response to a command by a user.

5. A method according to claim 3, wherein the command from the user is received via a user interface.

6. A method according to claim 3, wherein the command is a spoken command.

7. A method according to claim 1, wherein the communication link between the control system and the digital media storage device is wireless.

8. A method according to claim 1, wherein the plurality of entries includes any of the following:

song title, album title, artist, genre, time length, track number, elapsed time, recording label, recording date, composer, producer, and featured artist.

9. A method according to claim 1, wherein the memory is configured to include the stored data entries.

10. A method according to claim 1, wherein the stored data entries are configured to be updated from an external source.

11. A method according to claim 1, wherein the phonemic representations are configured to allow each entry to be speech recognized.

12. A control system in a vehicle for extracting meta data from a digital media storage device over a communication link, the system comprising:

a communication module for establishing a communication link with the digital media storage device;

a processing module coupled to the communication module, the processing module being configured to retrieve via the communication module meta data associated with a media file from the digital media storage device, the meta data including a plurality of entries, wherein at least one of the plurality of entries includes text data, the processing module being further configured to compare the text data of the entries with a set of stored data records; and

a memory module configured to store the plurality of entries retrieved from the digital media storage device.

13. A system according to claim 12, wherein if the text data matches at least one of the stored data records, the processing module being configured to generate a phonemic representation of the text data based on a phonemic representation of the stored data record, and if the text data does not match at least one of the stored data records, the processing module being further configured to generate a phonemic representation of the text data based on a phonemic representation of the text data from the entry.

14. A system according to claim 12, wherein the processing module is configured to identify the text data of an entry and generate a phonemic representation of the text data of the entry.

15. A system according to claim 12, further comprising a user interface configured to receive input, to select at least one media file based on the media file'"'"'s associated meta data, and to play the media file'"'"'s audio data via an audio system.

16. A system according to claim 12, wherein the user interface comprises a display and the processing module is configured to provide meta data to a user via the display.

17. A system according to claim 12, further comprising an audio input device configured to receive oral input commands from a user.

18. A system according to claim 12, further comprising a speech recognition module configured to compare oral input commands received from a user to a predetermined set of input commands, wherein the speech recognition module determines an appropriate response based on the oral input command.

19. A system according to claim 12, further comprising a text conversion engine configured to convert the text data of an entry to an audible speech representation of the text data.

20. A system according to claim 12, wherein the phonemic representation of the text data of an entry is configured to facilitate speech recognition of the entry of the media file
