`
`FIG. 13a is a block diagram showing an alternate embodiment of the
`
`multimedia device integration system 710 of the present invention, wherein
`
`5
`
`configuration jumpers 720 and protocol conversion software blocks 724 are
`
`provided for integrating after-market devices of various types using a single
`
`interface. The jumpers 720 can be set to a plurality of different settings, each of
`
`which corresponds to an after-market device of a specific type (e.g., CD changer.
`
`CD player, digital media player, satellite radio, video device, cellular telephone,
`
`10
`
`etc.) or from a specific manufacturer. Additionally, the jumpers 720 can be used to
`
`specify one or more device or manufacturer types for the car stereo or video
`
`system 705. The settings of the configuration jumpers 720 correspond to one or
`
`more protocol conversion software blocks 724 stored in memory (e.g..
`
`programmable flash memory, ROM, EEPROM, etc.) 725 of the interface 710.
`
`15 Each of the software blocks 724 controls the interface circuitry 715 and contains
`
`instructions for converting data from the device 707 into a format compatible with
`
`the car stereo or video system 705, and vice versa. For example, a first block could
`
`contain software for allowing communication between an Apple iPod and an in-
`
`dash car stereo manufactured by Sony, and a second block could contain software
`
`20
`
`for allowing communication between a DVD player and a car video system. Any
`
`desired number of blocks could be stored in the memory 725 and can be selected as
`
`desired by the user via configuration jumpers 720. As such, a single interface 710
`
`can be used for integrating numerous devices of various types and manufactures
`
`for use with one or more car stereo or video systems.
`
`The device 710 could
`
`61
`
`
`
`WO 2006/094281
`
`PCT/US2006/008043
`
`include one or more of the circuits shown in FIGS. 3a-3d, with modifications
`
`depending upon the device types of the devices 705 and 707.
`
`FIG. 13b is a block diagram showing an alternate embodiment of the
`
`multimedia device integration system of the present invention, wherein wiring
`
`5
`
`harnesses 727 and 728 and protocol conversion software blocks 729 are provided
`
`for integrating multimedia devices of various types using a single interface 726. In
`
`this embodiment, the electrical configurations (pinouts) of each of the harnesses
`
`727 and 728 correspond to car stereo / video systems and after-market devices of
`
`specific types and made by specific manufacturers (e.g., harness 727 could
`
`10
`
`correspond to a BMW car stereo, and harness 728 could correspond to an ALPINE
`
`satellite tuner). The electrical configurations (pinouts) of the harnesses are utilized
`
`by the interface 726 to retrieve a specific protocol conversion software block 729
`
`that allows communication between the devices. The interface 726 could be
`
`provided with a plurality of protocol conversion software blocks pre-loaded into
`
`15 memory in the interface, and could be provided with any desired harnesses. The
`
`interface 726 could include one or more of the circuits shown in FIGS. 3a-3d, with
`
`modification depending upon the device types of the devices attached to the wiring
`
`harnesses 727 and 728.
`
`FIG. 14 is a flowchart showing processing logic, indicated generally at
`
`20
`
`730, of the multimedia device integration system of the present invention for
`
`integrating after-market devices of various types using a single interface. In step
`
`735, the interface determines types of devices that are connected thereto, including
`
`the car stereo or video system and one or more after-market devices to be
`
`integrated therewith. This could be achieved by the configuration jumper settings
`
`62
`
`
`
`WO 2006/094281
`
`PCT/US2006/008043
`
`or the harness types connected to the interface and discussed with respect to FIGS.
`
`13a and 13b. Then, in step 740, a protocol conversion software block is selected
`
`from blocks of conversion software {e.g., from the blocks 725 and 729 shown in
`
`FIGS. 13a and 13b). In step 745, instructions are converted using the selected
`
`5
`
`conversion block to allow the car stereo or video system to operate with the
`
`multimedia device.
`
`.FIG. 15 is a flowchart showing processing logic, indicated generally at
`
`750, of the multimedia device integration system of the present invention for
`
`allowing a user to specify one or more after-market device types for integration
`
`10
`
`using a single interface. In step 770, a user is provided with one or more lists of
`
`devices to be integrated, which are displayed on the display 760 of the car stereo or
`
`video device 755. Then, in step 775, using the buttons 765 of the car video device.
`
`the user can specify the type of multimedia device to be integrated {e.g., by
`
`scrolling through the lists). Additionally, the device type could be specified using
`
`15
`
`a graphical or software menu displayed on the car stereo or car video system. In
`
`step 780, a determination is made as to whether a timeout has occurred {e.g., the
`
`user has not selected a device type within a predetermined period of time). If a
`
`positive determination is made, step 785 occurs, wherein a protocol conversion
`
`software block is selected from memory corresponding to the last device type
`
`20
`
`displayed by the car stereo or video system. If a negative determination is made,
`
`step 790 is invoked, wherein a determination is made as to whether the user has
`
`specified a device type. If a negative determination is made, step 775 is re-invoked
`
`so that the user can specify a device type. If a positive determination is made, step
`
`795 is invoked, wherein a protocol conversion software block is selected from
`
`63
`
`
`
`WO 2006/094281
`
`PCT/US2006/008043
`
`memory corresponding to the device specified by the user,
`
`In step 800, the
`
`protocol conversion software block is mapped to a logical address in memory.
`
`Then, in step 805, instructions to be exchanged between the car stereo or video
`
`system arid the after-market device are converted using the software block to allow
`
`5
`
`communication between the devices using compatible formats. Accordingly, the
`
`logic of FIG. 15 allows a single interface having multiple protocol conversion
`
`software blocks to be used integrate a plurality of after-market devices with a car
`
`stereo or video system.
`
`FIG. 16 is a flowchart showing processing logic of the multimedia device
`
`10
`
`integration system of the present invention, indicated generally at 810, for allowing
`
`a user to quickly navigate through a list of songs on one or more after-market
`
`devices using the controls of a car stereo or video system (fast navigation
`
`technique). This method allows a user to quickly select a song from a list of songs
`
`available on an after-market device for playing on the car stereo or video system.
`
`15
`
`and could be applied for use with any type of after-market device, including, but
`
`not limited to, a digital media player such as an MPS player or Apple iPod player.
`
`Beginning in step 812, a user is provided with a list of alphanumeric characters on
`
`a display of the car stereo or video system. This list could include the letters A
`
`through Z, as well as the numbers 0 through 9. In step 814, the user can specify a
`
`20
`
`desired alphanumeric character, which can be specified by scrolling through the
`
`list using one or more controls of the car stereo or video system and pressing a
`
`button once the desired character has been highlighted, or optionally, if an
`
`alphanumeric keypad (or touchscreen interface) is provided on the car stereo or
`
`video system, the user can directly enter the desired alphanumeric character.
`
`64
`
`
`
`WO 2006/094281
`
`PCT/US2006/008043
`
`When the desired alphanumeric character has been specified, in step 816 a
`
`remote database is queried using the alphanumeric character. The remote database
`
`could comprise a list of songs stored in one or more after-market devices integrated
`
`5
`
`by the present invention for use with the car stereo or video system. In step 818, a
`
`list of potentially matching songs is retrieved from the database and presented on
`
`the display of the car stereo or video system for perusal by the user. For example,
`
`if the user specified the letter "A," the list could include all songs in the remote
`
`database having titles (or artists) beginning with the letter "A." In step 820, a
`
`10
`
`determination is made as to whether a desired song appears in the list and is
`
`immediately viewable by the user, without requiring the user to scroll through the
`
`list. If a positive determination is made, step 822 is invoked, wherein the desired
`
`song is selected by the user and retrieved from the after-market device for playing
`
`on the car stereo or video system.
`
`15
`
`In the event that a negative determination is made in step 820, step 824 is
`
`invoked, wherein the user can specify an additional alphanumeric character using
`
`the car stereo or video system. For example, if the user initially specified the letter
`
`"A" and the desired song is not visible in the list of songs without scrolling, the
`
`user can refine the query by adding an additional alphanumeric character. Thus,
`
`20
`
`for example, the user can specify the letters "AN" to search for songs having titles
`
`(or artists) beginning with the letters "AN." In step 826, the remote database of the
`
`after-market device is queried using the specified letters. In step 828, a list of
`
`potential matches is presented to the user at the car stereo or video system. In step
`
`830, a determination is made as to whether the desired song appears in the list and
`
`65
`
`
`
`WO 2006/094281
`
`PCT/US2006/008043
`
`is immediately viewable without requiring the user to scroll through the list. If a
`
`positive determination is made, step 822 is invoked, wherein the user can select the
`
`desired song for retrieval from
`
`the after-market device and playing on the car
`
`stereo or video system. If a negative determination is made, step 832 is invoked,
`
`5 wherein a determination is made as to whether a threshold number of alphanumeric
`
`characters has been specified by the user. For example, a maximum threshold of 3
`
`alphanumeric characters could be specified, or any other desired number. If a
`
`negative determination is made, steps 824-832 are re-invoked in the manner
`
`disclosed herein to allow the user to specify additional alphanumeric characters for
`
`10
`
`querying the remote database. If a positive determination is made (threshold met),
`
`then processing terminates and the user must scroll through the list of retrieved
`
`songs or repeat the processing disclosed in FIG. 16 to begin a new query.
`
`FIG. 17 is a diagram showing an another embodiment of the present
`
`invention, indicated generally at 850, wherein a plurality of external devices are
`
`15
`
`integrated using a single interface 852. Any desired number or combination of
`
`devices can be integrated for use with a car stereo or video system using the
