`FIELD OF THE INVENTION
`
`The present invention relates to a multimedia device integration system. More
`
`25
`
`specifically, the present invention relates to a multimedia device integration system for
`
`integrating after-market components such as satellite receivers, CD players, CD changers, digital
`
`media devices (e.g., MP3 players, MP4 players, WMV players, Apple iPod devices, portable
`
`media centers, and other devices), Digital Audio Broadcast (DAB) receivers, auxiliary audio
`
`sources, video devices (e.g., DVD players), cellular telephones, and other devices for use with
`
`30
`
`factory-installed (OEM) or after-market car stereo and video systems.

`
`RELATED ART
`
`Automobile audio systems have continued to advance in complexity and the number of
`
`options available to automobile purchasers. Early audio systems offered a simple AM and/or
`
`FM tuner, and perhaps an analog tape deck for allowing cassettes, 8-tracks, and other types of
`
`5
`
`tapes to be played while driving. Such early systems were closed, in that external 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
`
`10
`
`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, digital
`
`media players (e.g., Apple iPod, MP3, MP4, WMV, etc.), CD changers, auxiliary input sources,
`
`video devices (e.g., DVD players), cellular telephones, and the like, to be easily integrated
`
`15
`
`therewith. Thus, automobile purchasers are frequently forced to either entirely replace the OEM
`
`audio system, 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 frequently is
`
`not operable with an external device.
`
`20
`
`A particular problem with integrating after-market audio and video systems with existing
`
`car stereo and video systems is that signals generated by both systems are in proprietary formats,
`
`and are 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
`
`2
`
`ME1\5677906.1
`
`Page 2 of 138

`

`

`Express Mail Label No.: EV623706889US
`
`the car stereo or video system. Thus, in order to integrate after-market systems with existing car
`
`stereo and video systems, it is necessary to convert signals between such systems.
`
`It known in the art to provide one or more expansion modules for OEM and after-market
`
`5
`
`car stereos for allowing external 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
`
`manufactured by TOYOTA or an after-market car radio manufactured by CLARION, Inc. Thus,
`
`10
`
`existing expansion modules only serve the limited purpose of integrating equipment by the same
`
`manufacturer as the car stereo. Thus, it would be desirable to provide an integration system that
`
`allows any audio device of any manufacture to be integrated with any OEM or after-market radio
`
`system.
`
`Further, radio-frequency (RF) transmitters and cassette tape adapters have been
`
`developed for allowing music from a device external to a car radio, such as a portable CD player,
`
`15
`
`to be played through the car radio using the FM receiver or the cassette deck of the radio.
`
`However, such systems are often prone to interference, and do not provide high fidelity.
`
`Moreover, it would be desirable to provide an integration system that not only achieves
`
`integration of various audio and video devices that are alien to a given OEM or after-market car
`
`20
`
`stereo or video system, but also allows for information to be exchanged between the after-market
`
`device and the car stereo or video system. 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 the car stereo or video system for display thereby, such as
`
`3
`
`ME1\5677906.1
`
`Page 3 of 138
`
`

`

`'Express Mail Label No.: EV623706889US
`
`at an LCD panel of the car stereo or on one or more display panels of a car video system. Such
`
`information could be transmitted and displayed on both hardwired car stereo and video 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
`
`5
`
`panels. Additionally, it would be desirable to provide a multimedia device integration 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 or video system. Still further, it would be desirable to provide a
`
`multimedia device integration system that allows for wireless integration of portable devices for
`
`10
`
`use with car audio and/or video systems, wherein full remote control of the portable device is
`
`provided at the controls of the car system.
`
`Accordingly, the present invention addresses these needs by providing a multimedia
`
`device integration system that allows a plurality of after-market devices, such as CD players, CD
`
`15
`
`changers, digital media devices (e.g., MP3 players, MP4 players, Apple iPod, WMV players,
`
`portable media centers, and other devices), satellite receivers, DAB receivers, auxiliary input
`
`sources, video devices (e.g., DVD players), cellular telephones, or any combination thereof, to be
`
`integrated into existing car stereo and video systems while allowing information to be displayed
`
`on, and control to be provided from, the car stereo or video system.

`
`SUMMARY OF THE INVENTION
`
`The present invention relates to a multimedia device integration system. One or more
`
`after-market audio devices, such as CD players, CD changers, digital media devices (e.g., MPS
`
`players, MP4 players, WMV players, Apple iPod devices, portable media centers, and other
`
`5
`
`devices), satellite receivers (e.g., XM or Sirius receivers), digital audio broadcast (DAB)
`
`receiver, or auxiliary input sources, 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
`
`10
`
`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 device.
`
`The formatted commands are executed by the after-market device, and audio therefrom is
`
`15
`
`channeled to the car stereo. Information from the after-market 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 connected to the present
`
`20
`
`invention. The information can be presented as one or more menus, textual, or graphical
`
`prompts for display on an LCD display of the radio, allowing interaction with the user at the
`
`radio. A docking port may be provided for allowing portable external audio devices to be
`
`connected to the interface of the present invention.

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`The present invention relates to a multimedia device integration system. One or more
`
`after-market devices, such as a CD player, CD changer, digital media player (e.g., MPS player,
`
`MP4 player, WMV player, Apple iPod, portable media center, or other device), satellite receiver,
`
`5
`
`digital audio broadcast (DAB) receiver, video device (e.g., DVD player), cellular telephone, or
`
`the like, can be integrated with an existing car radio or car video device, such as an OEM or
`
`after-market car stereo or video system. Control of the after-market device is enabled using the
`
`car stereo or car video system, and information from the after-market device, such as channel,
`
`artist, track, time, song, and other information, is retrieved form the
`
`after-market device,
`
`10
`
`processed, and forwarded to the car stereo or car video system
`
`for display thereon. The
`
`information channeled to the car stereo or video system can include video from the external
`
`device, as well as graphical and menu-based information. A user can review and interact with
`
`information via the car stereo. Commands from the car stereo or video system are received,
`
`processed by the present invention into a format recognizable by the after-market device device,
`
`15
`
`and transmitted thereto for execution. One or more auxiliary input channels can be integrated by
`
`the present invention with the car stereo or video system. The user can switch between one or
`
`more after-market devices and one or more auxiliary input channels using the control panel
`
`buttons of the car stereo or video system.
`
`20
`
`As used herein, the term "integration" or "integrated" is intended to mean connecting one
`
`or more external devices or inputs to an existing car stereo or video system via an interface,
`
`processing and handling signals, audio, and/or video information, allowing a user to control the
`
`devices via the car stereo or video system, and displaying data from the devices on the car stereo

`
`or video system. Thus, for example, integration of a CD player with a car stereo system allows
`
`for the CD player to be remotely controlled via the control panel of the stereo system, and data
`
`from the CD player to be sent to the display of the stereo. Of course, control of after-market
`
`devices can be provided at locations other than the control panel of the car stereo or video system
`
`5 without departing from the spirit or scope of the present invention. Further, as used herein, the
`
`term "inter-operable" is
