Abstract

A vehicle audio system 30 reconfigures with a PDAD 32 device by sending a series of queries through a supported channel, preferably a UART channel to the PDAD with the PDAD sending back requested control information 42 and meta-data housing information 46.

Claims

1. A system for integrating a personal digital audio device to an audio system having a display and control buttons, said audio system and personal digital audio device connected together through a communication channel therebetween;

an audio path between the personal digital audio device and audio system;

said system comprising;

said personal digital audio device sending a device identification packet through the communication channel to said audio system;

said audio system sending back an acknowledgement receiving said device identification and sending supported baud rates along said communication channel to said personal digital audio device;

said personal digital audio device sending an acknowledgement of receiving supported baud rates and confirming a top supported baud rate;

said audio system sending acknowledgement of receiving confirmation along with playback control query;

said personal digital audio device sending acknowledgement of receipt of playback control query along with playback control codes for requested commands;

said audio system sending an acknowledgement of receiving said playback control codes and sending a meta-data browsing query;

said personal digital audio device sending an acknowledgement of receiving said meta-data browsing query along with meta-data in-state browsing codes;

said audio system sending an acknowledgement of receiving said meta-data browsing codes and sending reconfiguration notification to said personal digital audio device;

said audio system and said personal digital audio device reconfigure to operable communication along the communication channel; and

said personal digital audio device awaits a command from said audio system.

2. A system as defined in claim 1 wherein said audio system is a vehicular audio system.

3. A system as defined in claim 2 wherein said playback codes include, play, stop, pause, fast forward, fast reverse, previous and next commands.

4. A system as defined in claim 3 wherein said meta-data browsing codes include select and back between two states and next and previous for in-state browsing.

5. A system as defined in claim 2 wherein said meta-data browsing codes include select and back between two states and next and previous for in-state browsing.

6. A system as defined in claim 1 wherein said meta-data in-state browsing codes include select and back between two states and next and previous for in-state browsing.

7. A system as defined in claim 1 wherein said playback codes include, play, stop, pause, fast forward, fast reverse, previous and next commands.

8. A system as defined in claim 1 wherein said communication channel is supported by UART at both the audio system and the personal digital audio device.

9. A system for integrating a personal digital audio device to a vehicular audio system having its own display and control buttons;

said personal digital audio device and said vehicular audio system connected together through a communication channel;

said personal digital audio device and said vehicular audio system having an audio channel connected therebetween;

said system comprising;

said personal digital audio device sending a series of information packets to said vehicular audio system including device identification, confirmation of supported baud rates, playback control code information and meta-data browsing code information; and

said vehicular audio system sending a series of information packets to said personal digital audio device including, supported baud rates, playback control queries, meta-data browsing queries and a configuration notice; and

said personal digital audio device and said vehicular audio system each reconfigure to provide communication to the other through the communication channel.

10. A system as defined in claim 9 wherein said playback control information includes play, stop, pause, fast forward, fast reverse, previous and next commands.

11. A system as defined in claim 10 wherein said meta-data browsing code information includes select and back between two states and next and previous for in-state browsing.

12. A system as defined in claim 9 wherein said meta-data browsing code information includes select and back between two states and next and previous for in-state browsing.

13. A system as defined in claim 9 wherein said communication channel is supported by UART at both the audio system and the personal digital audio device.
