`AUDIO DEVICE INTEGRATION SYSTEM
`
`BACKGROUND OF THE INVENTION
`
`1. Field of the Invention
`
`The present invention relates to an audio device integration
`system. More specifically, the present invention relates to an
`audio device integration system for integrating after-market
`components such as satellite receivers, CD players, CD
`changers, MP3 players, Digital Audio Broadcast (DAB)
`receivers, auxiliary audio sources, and the like with factory-
`installed (OEM) or after-market car stereo systems.
`2. Related Art
`
`Automobile audio systems have continued to advance in
`complexity and the number of options available to automo-
`bile purchasers. Early audio systems offered a simple AM
`and/or FM tuner, and perhaps an analog tape deck for allow-
`ing cassettes, 8-tracks, and other types of tapes to be played
`while driving. Such early systems were closed, in that exter-
`nal devices could not be easily integrated therewith.
`With advances in digital technology, CD players have been
`included with automobile audio systems. Original Equipment
`Manufacturers (OEMs) often produce car stereos having CD
`players and/or changers for allowing CDs to be played while
`driving. However, such systems often include proprietary
`buses and protocols that do not allow after-market audio
`systems, such as satellite receivers (e.g., XM satellite tuners),
`digital audio broadcast (DAB) receivers, MP3 players, CD
`changers, auxiliary input sources, and the like, to be easily
`integrated therewith. Thus, automobile purchasers are fre-
`quently forced to either entirely replace the OEM audio sys-
`tem, or use same throughout the life of the vehicle or the
`duration of ownership. Even if the OEM radio is replaced
`with an after-market radio, the after-market radio also fre-
`quently is not operable with an external device.
`A particular problem with integrating after-market audio
`systems with existing car stereos is that signals generated by
`the car stereo is in a proprietary format, and is not capable of
`being processed by the after-market system. Additionally,
`signals generated by the after-market system are also in a
`proprietary format that is not recognizable by the car stereo.
`Thus, in order to integrate after-market systems with car
`stereos, it is necessary to convert signals between such sys-
`tems.
`
`It known in the art to provide one or more expansion
`modules for OEM and after-market car stereos for allowing
`extemal audio products to be integrated with the car stereo.
`However, such expansion modules only operate with and
`allow integration of external audio products manufactured by
`the same manufacturer as the OEM/after-market car stereo.
`
`For example, a satellite receiver manufactured by PIONEER,
`Inc., cannot be integrated with an OEM car radio manufac-
`tured by TOYOTA or an after-market car radio manufactured
`by CLARION, Inc. Thus, existing expansion modules only
`serve the limited purpose of integrating equipment by the
`same manufacturer as the car stereo. Thus, it would be desir-
`able to provide an integration system that allows any audio
`device of any manufacture to be integrated with any OEM or
`after-market radio system.
`Moreover, it would be desirable to provide an integration
`system that not only achieves integration of various audio
`devices that are alien to a given OEM or after-market stereo
`system, but also allows for information to be exchanged
`between the after-market device and the car stereo. For
`
`example, it would be desirable to provide a system wherein
`station, track, time, and song information can be retrieved
`from the after-market device, formatted, and transmitted to
`
`10
`

`

`

`
`the car stereo for display thereby, such as at an LCD panel of
`the car stereo. Such information could be transmitted and
`
`displayed on both hardwired radio systems (e.g., radios
`installed in dashboards or at other locations within the car), or
`integrated for display on one or more software or graphically-
`driven radio systems operable with graphical display panels.
`Additionally, it would be desirable to provide an audio inte-
`gration system that allows a user to control more than one
`device, such as a CD or satellite receiver and one or more
`auxiliary sources, and to quickly and conveniently switch
`between same using the existing controls of the car stereo.
`Accordingly, the present invention addresses these needs
`by providing an audio integration system that allows a plu-
`rality of audio devices, such as CD players, CD changers,
`MP3 players, satellite receivers, DAB receivers, auxiliary
`input sources, or a combination thereof, to be integrated into
`existing car stereos while allowing information to be dis-
`played on, and control to be provided from, the car stereo.
`
`SUMMARY OF THE INVENTION
`
`The present invention relates to an audio device integration
`system. One or more after-market audio devices, such as a CD
`player, CD changer, MP3 player, satellite receiver (e.g., XM
`tuner), digital audio broadcast (DAB) receiver, or auxiliary
`input source, can be connected to and operate with an existing
`stereo system in an automobile, such as an OEM car stereo
`system or an after-market car stereo system installed in the
`automobile. The integration system connects to and interacts
`with the car stereo at any available port of the car stereo, such
`as a CD input port, a satellite input, or other known type of
`connection. If the car stereo system is an after-market car
`stereo system, the present invention generates a signal that is
`sent to the car stereo to keep same in an operational state and
`responsive to external data and signals. Commands generated
`at the control panel are received by the present invention and
`converted into a format recognizable by the after-market
`audio device. The formatted commands are executed by the
`audio device, and audio therefrom is channeled to the car
`stereo. Information from the audio device is received by the
`present invention, converted into a format recognizable by the
`car stereo, and forwarded to the car stereo for display thereby.
`The formatted information could include information relating
`to a CD or MP3 track being played, channel, song, and artist
`information from a satellite receiver or DAB receiver, or
`video information from one or more external devices con-
`
`nected to the present invention. The information can be pre-
`sented as one or more menus, textual, or graphical prompts
`for display on an LCD display of the radio, allowing interac-
`tion with the user at the radio. A docking port is provided for
`allowing portable extemal audio devices to be connected to
`the interface of the present invention.
`In an embodiment of the present invention, a dual-input
`device is provided for integrating both an external audio
`device and an auxiliary input with an OEM or after-market car
`stereo. The user can select between the external audio device
`
`and the auxiliary input using the controls ofthe car stereo. The
`invention can automatically detect the type of device con-
`nected to the auxiliary input, and integrate same with the car
`stereo.
`
`In another embodiment of the present invention, an inter-
`face is provided for integrating a plurality of auxiliary input
`sources with an existing car stereo system. A user can select
`between the auxiliary sources using the control panel of the
`car stereo. One or more after-market audio devices can be
`
`integrated with the auxiliary input sources, and a user can
`switch between the audio device and the auxiliary input

`sources using the car stereo. Devices connected to the auxil-
`iary input sources are inter-operable with the car stereo, and
`are capable of exchanging commands and data via the inter-
`face.
