Abstract

A method is provided 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 includes establishing a communication link between control module of the vehicle and the digital media storage device, identifying a media file on the digital media storage device, and retrieving meta data from a media file, the meta data including a plurality of entries, wherein at least one of the plurality of entries includes text data. The method further includes identifying the text data in an entry of the media file and storing the plurality of entries in a memory.

Claims

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

establishing a first communication link between the control module of the vehicle and a first media device;

identifying a first plurality of media files on the first media device;

extracting first meta data from the first plurality of media files, the first meta data including a first plurality of entries, wherein at least one of the first plurality of entries includes text data;

identifying the text data in entries of the first meta data of the first plurality of media files;

storing the first plurality of entries in a non-volatile memory as a first database of entries of meta data pertaining to the first plurality of media files and having a unique identifier associated with the first media device;

establishing a second communication link between the control module of the vehicle and a second media device;

identifying a second plurality of media files on the second media device;

extracting second meta data from the second plurality of media files, the second meta data including a second plurality of entries, wherein at least one of the second plurality of entries includes text data;

identifying the text data in entries of the second meta data of the plurality of media files; and

storing the second plurality of entries in the non-volatile memory as a second database of meta data pertaining to the second plurality of media files and having a unique identifier associated with the second media device,

wherein the second database of the second plurality of entries of meta data is only accessible to a user of the control system when the second media device is connected with the control module via the second communication link and the control module receives the second unique identifier corresponding with the second media device, and wherein the first database of the first plurality of entries of meta data is only accessible to the user of the control system when the first media device is connected with the control module via the first communication link and the control module receives the unique identifier corresponding with the first media device.

2. A method according to claim 1, wherein the first meta data or the second meta data are retrieved in response to establishing the first communication link between the control module and the first media device or establishing the second communication link between the control module and the second media device.

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

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

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

6. A method according to claim 1, wherein at least one of the first communication link between the control module and the first media device or the second communication link between the control module and the second media device is wireless.

7. A method according to claim 1, wherein at least one of the first plurality of entries or the second 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.

8. A method according to claim 1, further comprising generating an acoustic baseform of the text data for an entry;

and

storing the acoustic baseform for the entry in a baseform list corresponding to at least one of the first database of meta data or the second database of meta data.

9. A method according to claim 8, wherein the acoustic baseform is configured to allow each entry to be speech recognized.

10. A method according to claim 1, further comprising identifying a playlist on the first media device or the second media device;

and

retrieving the playlist from the first media device or the second media device, wherein the playlist includes a custom arrangement of media files.

11. A control system in a vehicle for extracting meta data from media devices in the vehicle over a communication link, the system comprising:

a communication module for establishing a first communication link with a first media device;

a processing module coupled to the communication module, the processing module being configured to extract, via the communication module, first meta data associated with a first plurality of media files from the first media device, and wherein the first meta data includes a first plurality of entries, wherein at least one of the first plurality of entries includes text data; and

a non-volatile memory module configured to store the first plurality of entries retrieved from the first media device as a first database of entries of meta data pertaining to the first plurality of media files and having a unique identifier associated with the first media device;

wherein the communication module is further configured to establish a second communication link with a second media device,

wherein the processing module is further configured to extract, via the communication module, second meta data associated with a second plurality of media files from the second media device, the second meta data including a second plurality of entries, at least one entry including text data,

wherein the memory module is further configured to store the second plurality of entries retrieved from the second media device as a second database of entries of meta data pertaining to the second plurality of media files and having a second unique identifier associated with the second media device, and

wherein the control system is configured to allow access, by a user of the control system, to the second database of the second plurality of entries of meta data based on a connection status of the second media device and the second unique identifier corresponding with the second media device, and the control system is configured to allow access, by the user of the control system, to the first database of the first plurality of entries of meta data based on the connection status of the first media device and the unique identifier corresponding with the first media device.

12. A system according to claim 11, 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.

13. 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.

14. 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.

15. A system according to claim 11, 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 by streaming-in the audio data from at least one of the first media device or the second media device.

16. A system according to claim 15, 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 11, further comprising an audio input device configured to receive oral input commands from a user.

18. A system according to claim 11, 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 11, wherein the system is configured to support media encoding/decoding algorithms, including any of the following:

MP3, MP3 Pro, Ogg Vorbis, Advanced Audio Coding (AAC), Windows Media Audio (WMA), and Waveform Audio (WAV).
