`
`FIELD OF THE INVENTION
`
`The present
`
`invention relates to a multimedia device integration system. More
`
`specifically,
`
`the present
`
`invention relates to a multimedia device integration system for
`
`integrating afier-market components such as satellite receivers, CD players, CD changers, digital
`
`media devices (e.g., MP3 players, MP4 players, WMV players, Apple iPod devices, and other
`
`similar devices), Digital Audio Broadcast (DAB) receivers, auxiliary audio sources, video
`
`devices (e.g., DVD players), cellular telephones, and other devices for use with 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
`
`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
`
`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 afier—marl<et 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
`
`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.
`
`A particular problem with integrating alter-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 alter-market system. Additionally, signals
`
`generated by the after-market system are also in a proprietary format that is not recognizable by
`
` 4
`
`

`
`the car stereo or video system. Thus, in order to integrate afier—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
`
`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,
`
`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.
`
`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
`
`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
`
`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
`
` 5
`
`

`
`on one or more software or graphically—driven radio systems operable with graphical display
`
`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.
`
`Accordingly,
`
`the present
`
`invention addresses these needs by providing a multimedia
`
`device integration system that allows a plurality of alter-market devices, such as CD players, CD
`
`changers, digital media devices (e. g., MP3 players, MP4 players, Apple iPod, WMV players, and
`
`other similar 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
`
`alter-market audio devices, such as CD players, CD changers, digital media devices (e.g., MP3
`
`players, MP4 players, WMV players, Apple iPod devices, and other similar 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 afier—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 connector.
`
`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 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
`
`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., MP3 player,
`
`MP4 player, WMV player, Apple iPod, or other similar player), satellite receiver, 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 information, is retrieved form the after—market device, 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, 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.
`
`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
`
`18
`
` 18
`
`

`
`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 alter-market
`
`devices can be provided at locations other than the control panel of the car stereo or video system
`
`without departing from the spirit or scope of the present invention. Further, as used herein, the
`
`term “inter—operable” is intended to mean allowing the external audio or video device to receive
`
`and process commands that have been formatted by the interface of the present invention, as well
`
`as allowing a car stereo or video system to display information that is generated by the external
`
`audio or video device and processed by the present invention. Additionally, by the term “inter-
`
`operable,” it is meant allowing a device that is alien to the environment of an existing OEM or
`
`after-market car stereo or video system to be utilized thereby.
`
`Also, as used herein, the terms “car stereo” and “car radio” are used interchangeably and
`
`are intended to include all presently existing car stereos and radios, such as physical devices that
`
`are present at any location within a vehicle,
`
`in addition to software and/or graphically- or
`
`display-driven receivers. An example of such a receiver is a software—driven receiver that
`
`operates on a universal LCD panel within a vehicle and is operable by a user via a graphical user
`
`interface displayed on the universal LCD panel.
`
`Further, any future receiver, whether a
`
`hardwired or a software/graphical receiver operable on one or more displays,
`
`is considered
`
`within the definition of the terms “car stereo” and “car radio,” as used herein, and is within the
`
`spirit and scope of the present invention. Moreover, the term “car” is not limited to any specific
`
`type of automobile, but rather,
`
`includes all automobiles. Additionally, by the term “after-
`
`market,” it is meant any device not installed by a manufacturer at the time of sale of the car.

`

`
`FIG. 1 is a block diagram showing the multimedia device integration (or interface)
`
`system of the present invention, generally indicated at 20. A plurality of devices and auxiliary
`
`inputs can be connected to the interface 20, and integrated with an OEM or after-market car
`
`radio 10. A CD player or changer 15 can be integrated with the radio 10 via interface 20. A
`
`satellite radio or DAB receiver 25, such as an XM or Sirius radio satellite receiver or DAB
`
`receiver known in the art, could be integrated with the radio 10, via the interface 20. Further, an
`
`MP3 player 30 could also be integrated with the radio 10 via interface 20. The MP3 player 30
`
`could be any known digital media device, such as an Apple iPod or any other digital media
`
`device. Moreover, a plurality of auxiliary input sources, illustratively indicated as auxiliary input
`
`sources 35 (comprising input sources 1 through n, n being any number), could also be integrated
`
`with the car radio 10 via interface 20. Optionally, a control head 12, such as that commonly used
`
`with after-market CD changers and other similar devices, could be integrated with the car radio
`
`10 via interface 20, for controlling any of the car radio 10, CD player/changer 15, satellite/DAB
`
`receiver 25, MP3 player 30, and auxiliary input sources 35. Thus, as can be readily appreciated,
`
`the interface 20 of the present invention allows for the integration of a multitude of devices and
`
`inputs with an OEM or after-market car radio or stereo.
`
`FIG. 2a is a block diagram of an alternate embodiment of the multimedia device
`
`interface system of the present invention, wherein a CD player/changer 15 is integrated with an
`
`OEM or after-market car radio 10. The CD player 15 is electrically connected with the interface
`
`20, and exchanges data and audio signals therewith. The interface 20 is electrically connected
`
`with the car radio 10, and exchanges data and audio signals therewith.
`
`In a preferred
`
`20
`
` 20
`
`

`
`embodiment of the present
`
`invention,
`
`the car radio 10 includes a display 13 (such as an
`
`alphanumeric, electroluminescent display) for displaying information, and a plurality of control
`
`panel buttons 14 that normally operate to control the radio 10. The interface 20 allows the CD
`
`player 15 to be controlled by the control buttons 14 of the radio 10. Further, the interface 20
`
`allows information from the CD player 15, such as track, disc, time, and song information, to be
`
`retrieved therefrom, processed and formatted by the interface 20, sent to the display 13 of the
`
`radio 10.
`
`Importantly, the interface 20 allows for the remote control of the CD player 15 from the
`
`radio 10 (e.g., the CD player 15 could be located in the trunk of a car, while the radio 10 is
`
`mounted on the dashboard of the car). Thus, for example, one or more discs stored within the
`
`CD player 15 can be remotely selected by a user from the radio 10, and tracks on one or more of
`
`the discs can be selected therefrom. Moreover, standard CD operational commands, such as
`
`pause, play,
`
`stop,
`
`fast
`
`forward,
`
`rewind,
`
`track forward, and track reverse (among other
`
`commands) can be remotely entered at the control panel buttons 14 of the radio 10 for remotely
`
`controlling the CD player 15.
`
`FIG. 2b is a block diagram showing an alternate embodiment of the present invention,
`
`wherein an MP3 player 30 is integrated with an OEM or after-market car radio 10 via interface
`
`20. As mentioned earlier, the interface 20 of the present invention allows for a plurality of
`
`disparate audio devices to be integrated with an existing car radio for use therewith. Thus, as
`
`shown in FIG. 2b, remote control of the MP3 player 30 via radio 10 is provided for via interface
`
`20. The MP3 player 30 is electronically interconnected with the interface 20, which itself is
`
`21
`
` 21
`
`

`
`electrically interconnected with the car radio 10. The interface 20 allows data and audio signals
`
`to be exchanged between the MP3 player 30 and the car radio 10, and processes and formats
`
`signals accordingly so that instructions and data from the radio 10 are processable by the MP3
`
`player 30, and vice versa. Operational commands, such as track selection, pause, play, stop, fast
`
`forward, rewind, and other commands, are entered via the control panel buttons 14 of car radio
`
`10, processed by the interface 20, and formatted for execution by the MP3 player 30. Data from
`
`the MP3 player, such as track, time, and song information,
`
`is received by the interface 20,
`
`processed thereby, and sent to the radio 10 for display on display 13. Audio from the MP3
`
`player 30 is selectively forwarded by the interface 20 to the radio 10 for playing.
`
`FIG. 2c is a block diagram showing an alternate embodiment of the present invention,
`
`wherein a satellite receiver or DAB receiver 25 is integrated with an OEM or after—market car
`
`radio 10 via the interface 20. Satellite/DAB receiver 25 can be any satellite radio receiver
`
`known in the art, such as XM or Sirius, or any DAB receiver known in the art.
`
`The
`
`satellite/DAB receiver 25 is electrically interconnected with the interface 20, whic
