Problems solved by technology

While the previous arrangement of six CD selection buttons provided an inherently intuitive and convenient method of making audio selections, minimizing the chance of operator distraction (e.g., one-button operation to select and playback desired audio from a CD almost instantaneously) , there is no equivalent intuitive and convenient audio selection method for selecting and playing back personal digital media device content compatible with existing car audio systems

Embodiment Construction

[0020] FIG. 1 provides a schematic diagram of one embodiment of an integrated system 1 including a personal media device 2 (in this embodiment, Apple iPod 3rd generation, also referred to as iPod2 hereinafter) and a car digital audio system 3 according to the present invention Overview. The car audio system 3 includes a stereo head-mounted unit 4 located in the car dash panel, and includes, among other system components, a display panel, operator controls, audio signal amplifiers, and a central processing unit and Software that runs with the I-bus control system protocol. This software is encoded in the microcircuit (ie firmware) in this embodiment, but need not be so fixed. In addition, the head mounted unit 4 is equipped with external connectors, for example for receiving audio signals from external audio components, transmitting digital data and commands on a digital bus connecting the head mounted unit 4 and other components in the sound system, and outputting analog audi...

Abstract

A system and method for controlling a personal digital media device is provided, the system and method using the controls of a vehicle audio system. An interface unit receives and translates vehicle audio system control signals and forwards the translated signals in a form interpretable by the personal digital media device for execution. The interface unit may also receive responses from the personal digital media device and forward translated responses to the vehicle audio system for, for example, display in the vehicle audio system's display device. In response to predetermined control signals from the vehicle audio system, the interface unit may command the personal digital media device to playback user-defined playlists named in accordance with a playlist naming convention. The vehicle operator is thus provided an intuitive way to control the personal digital media device remotely via the vehicle audio system's controls, including via steering wheel-mounted audio system controls.

Description

technical field [0001] The present invention relates to a method and apparatus for controlling digital media devices, such as personal audio players, using the controls of a car's built-in audio system, and in particular using a car audio system's remote control, such as control buttons on a car steering wheel. Background technique [0002] Personal digital media devices are beginning to replace traditional hard-coded media, such as audio cassettes and compact discs, as the portable personal entertainment device of choice. Such devices receive audio content in digital format (songs, audiobooks, sound clips, etc.) via download, typically from a user's personal computer. Personal digital media devices store digital audio in on-board storage devices such as flash memory or microcomputer hard drives and provide a user interface for the user, usually allowing the user to access a database to select content to play. For example, the user interface may contain an index to allow th...
