1. A system for integrating a personal digital audio device to an audio system said audio system and personal digital audio device connected together through a communication channel without an interface unit 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.
