`
`Advertising information is preloaded into a collection of
`remote receiving and presentation devices. A presentation
`command delivered to the device then causes presentation of
`the stored advertisement. Each stored advertisement is also
`associated with one or more presentation conditions causing,
`when detected, automatic presentation. Such presentation
`conditions include proximity to a given location, scheduled
`periodic presentation, time of day presentation, and a variety
`of other conditions detectable at the remote presentation
`device. The illustrated method and apparatus for advertising
`presentation requires but a single broadcast signal transmis
`sion of a given advertisement, but provides multiple pre
`sentations of such advertisement at the presenting devices.
`In this manner, the advertiser enjoys ef?cient use of broad
`cast signal transmission time.

`
`The present invention delivers data and information
`including advertising information to a receiving device. In
`accordance with the present invention, data which can
`include advertising information is transmitted to a receiving
`device and then it is collected and stored within the receiving
`device. The receiving device intermittently presents stored
`information to a listener. The receiving device can provide
`multiple presentations of advertising information which was
`transmitted to the receiving device one time by radio signal.
`Presentation of the advertising information at the receiving
`device may be triggered by a variety of functions. Stored
`advertising information entries may be presented, for
`example, by reference to a time schedule, to current receiv
`ing device location, or to receiving device events such as
`power-up. Because the advertising information is broadcast
`only one time and presented multiple times, the advertiser
`incurs less expense for each advertisement presentation,
`there being multiple advertisement presentations for one
`radio signal transmission.
`The subject matter of the present invention is particularly
`pointed out and distinctly claimed in the concluding portion
`of this speci?cation. However, both the organization and
`method of operation of the invention, together with further
`advantages and objects thereof, may be best understood by
`reference to the following description taken with the accom
`panying drawings wherein like reference characters refer to
`like elements.

`
`FIELD OF THE INVENTION
`The present invention relates generally to vehicle infor
`mation systems, and particularly to vehicle information
`systems collecting and presenting information.
`
`BACKGROUND OF THE INVENTION
`Advertisement presentation requires, ?rst creation of
`advertisement information and subsequent dissemination by
`broadcast signal to receiving devices. To expose listeners to
`advertisements, the listeners must be monitoring the broad
`cast signal,.e.g., listening to the radio at the time of broad
`cast. Advertisers expend substantial etfort and expense in
`maximizing the number of listeners by timing advertisement
`broadcasts with expected times of target listening audiences.
`In other words, an advertisement is broadcast at particular
`times with the hope that the maximum number of listeners
`are exposed to the advertisement. Accordingly, certain
`broadcast times become most popular for advertisement
`broadcast and, therefore, the most expensive signal trans
`mission times.
`One of the traditional and long standing devices for
`delivering information to a vehicle is the car radio receiving
`radio transmissions from localAM or FM radio stations. The
`operator tunes the radio to a selected radio station and
`monitors information provided by radio broadcast concur
`rent with its transmission, i.e., listens to the radio announcer,
`advertisements, and the like concurrent with transmission
`via radio signal. To deliver a given advertisement to aradio,
`therefore, the radio must be on and tuned to the appropriate
`radio station concurrent with transmission of the advertise
`ment.
`Wide dissemination of advertising information requires
`multiple transmissions on multiple radio stations. The adver
`tiser thereby exposes more listeners to the advertising
`information, and thereby achieves a desired goal of exposing
`listeners to product or service information and availability.
`The advertiser must pay, however, for each advertising
`message transmission on each radio station. Accordingly,
`substantial expense is incurred in connection with broadcast
`of any given advertisement.
`It would be desirable to make the process of delivering
`advertising information to listeners more e?icient. In
`particular, it would be desirable disseminate such advertis
`ing information once and have the advertisement presented
`multiple times. The subject matter of the present invention
`provides such a method and apparatus for delivery of
`advertising information.
`
`DETAILED DESCRIPTION OF A PREFERRED
`EMBODIMENT
`The preferred form of the present invention provides a
`mechanism ef?ciently delivering advertising information to
`listeners. In the preferred form of the present invention, a
`receiving device which includes a combination of a car radio
`and a paging device collects and stores advertising infor
`mation for later presentation. Particular advertising infor
`
`65
`
`GOOGLE 1022
`Page 8
`
`

`
`3
`mation in the form of voice presentation or text presentation
`is sent to the receiving device by radio signal transmission
`once, and then presented multiple times at the receiving
`device. Once stored at a receiving device, a variety of
`conditions trigga' presentation of the advertisement. In the
`preferred embodiment shown herein the receiving device is
`a vehicle information device carried by a vehicle which
`collects data utilizing a paging system protocol to provide
`advertisement presentations.
`In FIG. 1, a vehicle 10 is shown within a road network 12.
`Network 12 includes main arterial roadways as illustrated,
`but it could be signi?cantly more complex. In the preferred
`embodiment shown herein, vehicle 10 can travel throughout
`road network 12 along any selected travel route. Road
`network 12 includes geographic points of interest 14, indi
`vidually designated 14a-14d associated with longitude and
`latitude positional
`While only several such geo
`graphic points of interest 14 are indicated in FIG. 1, any
`number of such geographic points of interest 14 may exist
`within road network 12. As described more fully hereafter,
`advertising information downloaded to the information
`device of vehicle 10 may be associated with certain geo
`graphic points of interest 14, i.e., the location at which
`advertised goods or services are available. As vehicle 10
`passes by or near such geographic points of interest 14, the
`receiving device of vehicle 10 holding a related advertise
`ment automatically presents such advertisement whereby
`the operator of vehicle 10 is exposed to an advertisement for
`goods or services at a nearby location.
`Radio broadcast system 20 provides a combined radio
`signal voice broadcast 22 and radio signal data broadcast 26.
`While illustrated as a single radio broadcast system 20, voice
`lxoadcast 22 and data broadcast 26 could originate from
`separate radio signal broadcast facilities. Under the pre
`ferred form of the present invention, however, voice broad
`cast 22 and data broadcast 26 originate from a common FM
`35
`radio source. The present invention may be implemented
`according to many paging system protocols, but as illus
`trated herein operates under the time-division multiplexed
`protocol of the paging system illustrated in U.S. Pat. Nos.
`4,713,808 and 4,897,835 and as commercially implemented
`by Seiko Telecommunication Systems, Inc. under the trade
`marks RECEPTOR and ACI'I'IV. Generally, the paging
`system uses FM radio signal transmission facilities to
`broadcast, within a side-band frequency, paging signal data
`packets according to a time-division multiplexed protocol.
`Thus, voice broadcast 22 comprises the normal FM radio
`signal broadcast and data broadcast 26 represents the side
`band paging system broadcast. ‘The paging system and
`associated receiving devices provide an inexpensive, highly
`battery-e?icient and highly miniaturized paging device
`which, under the illustrated embodiment of the present
`invention, constitutes a data radio receiver 62 (FIG. 2) as a
`conduit for data broadcast 26 delivery to device 40. The
`disclosure of US. Pat. Nos. 4,713,808 and 4,897,835 are
`incorporated herein fully by reference thereto.
`It will be understood, therefore, that radio broadcast
`system 20 provides coordinated voice and data by radio
`signal. Radio broadcast system 20 receives voice advertise
`ment and data message information 28, e.g., an advertising
`subscription, and integrates the data message portion thereof
`with other incoming paging system data packets originating
`from a paging system clearinghouse 30. The data message
`portion of information 28 could be routed through clearing
`house 30, in which case radio station 200 transmits data
`broadcast 26 as originating entirely from clearinghouse 30.
`In any event, radio station 20a transmits coordinated voice
`and data broadcasts 22 and 26.

`Vehicle 10 includes a travel information device 40 receiv
`ing by way of antenna 42 the voice broadcast 22 and data
`broadcast 26. Thus, device 40 receives conventional FM
`voice broadcasts and paging data packets transmitted under
`the paging system protocol. While illustrated herein as a
`vehicle travel information device, device 40 can also be any
`information device, e.g., a paging device, a personal radio,
`or portable personal computer.
`FIG. 1 also illustrates a global position system (GPS)
`satellite 50 providing transmission 52. Details and use of
`GPS transmission 52 to detennine location of a GPS
`receiver carried by vehicle 10 are well known. Use of GPS
`transmission 52 under the present invention ‘is by incorpo
`ration of a GPS receiving device into travel information
`device 40 and collection of current vehicle 10 position
`therewith as described more fully hereafter.
`Thus, travel information device 40 receives several chan
`nels of information. Voice broadcast 22 provided by radio
`broadcast system 20 provides a stream of analog voice
`information. Data broadcast 26 provides further advertising
`information, e.g., digital, voice or text information, to be
`captured by device 40. Third, the GPS transmission 52
`provides current vehicle location.
`As described more fully hereafter, device 40 captures and
`stores selected portions of voice and data broadcast 22 and
`26, i.e., advertisements. Once advertisements from voice
`and data broadcasts 22 and 26 are stored within device 40,
`subsequent conditions or explicit commands trigger presen
`tation thereof to the operator of vehicle 10 whereby a given
`advertisement may be presented multiple times to the opera
`tor of vehicle 10, yet need only be broadcast to receiving
`device 40 once. Conditions causing presentation of stored
`advertising information include, but need not be limited to,
`vehicle 10 being at or near a given geographic point of
`interest 14, e.g., by reference to current vehicle position,
`time of day, power-up of receiving device 40, or in response
`to a paging signal command delivered to receiving device 40
`and causing presentation of a selected advertisement stored
`within receiving device 40.
`FIG. 2 illustrates in block diagram travel information
`device 40. In FIG. 2, a microprocessor 60 orchestrates
`generally operation of device 40. While referred to generally
`herein as “microprocessor” 60, it will be understood that
`such device includes additional supporting hardware fea
`tures such as analog-to-conversion and digital-to-conversion
`and other such related input/output hardware required to
`support the features described herein. Data radio receiver 62
`couples antenna 42 to microprocessor 60. As contemplated
`under the preferred form of the present invention, data radio
`receiver 62 comprises essentially a paging system receiver
`operating under the paging system. Thus, the paging system
`paging device provided as receiver 62 serves as a data
`terminal collecting data broadcast 26 and providing to
`microprocessor 60 digital advertising, e.g., text or digitized
`voice data. A voice radio receiver 64, also coupled to
`antenna 42, receives the voice broadcast 22 and delivers a
`voice signal 66 to microprocessor 60 and to an amplifier 68
`driving speakers 70. Application of voice signal 66 to
`microprocessor 60 includes appropriate analog-to-digital
`conversion whereby microprocessor 60 converts, when
`necessary, voice signal 66 to a digitized recording thereof.
`Microprocessor 60 tunes voice radio receiver 64 and data
`radio 62 by way of a tune control signal 72. Thus, micro
`processor 60 establishes coordinated tuning for voice radio
`64 and data radio 62 whereby coordinated voice and data
`broadcast 22 and 26 are received by radios 64 and 62,
`respectively.

`A read/write memory resource 90 stores an indexed data
`table 90a containing advertisement records 400 available for
`presentation by device 40. Microprocessor 60 loads records
`400 into memory resource 90 in association with an appro
`priate index value and retrieves records 400 from the
`memory resource by providing an index value thereto.
`An advertisement presentation block 104 receives from
`microprocessor 60 an index value and has direct access to
`the memory resource 90 for presentation of advertisements
`stored therein. Thus, microprocessor 60 queues advertise
`ment presentation by providing a sequence of index values
`to the advertisement presentation block 104. The advertise
`ment presentation block, in turn, accesses memory resource
`90 by reference to a queued index value and collects the
`requested advertisement record 400 for presentation. As may
`be appreciated, message presentation block 104 reacts to the
`record 400 data type to determine how the advertisement
`data is to be interpreted and presented, i.e., selects one or
`both of display 100 and speakers 70 for presentation. Thus,
`advertisement presentation block 104 may deliver text type
`data taken from a record 400 to display 100 for presentation
`thereon, or may employ digitized sound data to produce an
`audio signal suitable for application to ampli?er 68 and
`presentation on speakers 70. Additionally, advertisement
`presentation block 104 may be provided with, for example,
`text-to-speech conversion capability for presentation of text
`type data found in one of records 400 upon speakers 70. In
`any case, advertisement presentation block 104 responds to
`the content, i.e., data type, of each record 400 queued for
`presentation and selects an appropriate mode of presentation
`by way of display 100 or ampli?er 68 and speakers 70.
`A global position system receiver 80 receives the trans
`mission 52 from global position system satellite 50 and
`delivers to microprocessor 60 a current vehicle location 82.
`In this manner, microprocessor 60 requests from global
`position system radio receiver 80 a current vehicle location
`and receives in return the current vehicle location 82.
`Display 100 presents, for example, tuning and station
`selection information relative to the voice radio receiver 60
`to provide an FM radio capability wherein the operator of
`vehicle 10 manipulates input controls 102, i.e., volume and
`station tuning, to listen to a selected voice broadcast 22.
`Display 100 further presents, advertising text as taken from
`advertisement records 400 having a text type data ?eld.
`FIG. 3 illustrates display 100 and input controls 102.
`Input controls 102 include a tune dial 102a, a volume dial
`102b and an AM/FM switch 1020. As may be appreciated,
`device 40 operates, from a user perspective, in part as a
`conventional car radio. Thus, the user manipulates input
`controls 102a-102c to listen to a voice broadcast 22 on
`speakers 70.
`FIG. 4 illustrates generally the structure of records 400
`maintained in device 40. In FIG. 4, each record 400 includes
`a unique index 400a, a condition list 400b, and a data type
`4000. As may be appreciated, the index 400a provides
`addressing to speci?c records held by device 40. Because
`broadcast system 20 is a one-way communication, assign
`ment of values to index 4000 for each record 400 is external
`of device 40, i.e., when advertising information is down
`loaded to device 40 it must be associated with a value for
`index 400a whereby an external entity references the index
`400a to, for example, trigger presentation of such advertis
`ing information. Thus, values for index 4000 are designated
`and later used by the source or entity placing information in
`device 40 by way of broadcast system 20.
`Condition list 400b for each record 400 provides a set of
`conditions indicating presentation of the associated adver
`
`50
`
`55
`
`65
`
`10
`
`25
`
`35
`
`40
`
`6
`tising information. For example, condition list 400b includes
`a schedule of presentation, a time of presentation, a location
`such as longitude and latitude where associated products or
`services are available, or a device 40 event such as power
`up. By scanning the condition lists 400b for a collection of
`records 400 and comparing such conditions to current
`detected conditions, device 40 determines when a given
`advertisement stored in device 40 need be presented
`Data type ?eld 4000 indicates the type of data held in each
`record 400. As may be appreciated, data ?eld 400d may
`include a variety of data types, e.g., text, digitized voice
`data, graphics data and special data formats such as mixed
`data type. Thus, when a given advertisement record 400 is
`to be presented, the data type ?eld 400a dictates how the data
`?eld 400d is interpreted and presented by device 40.
`As may be appreciated, in may instances the data ?eld
`400d must be of substantial size. Under the paging system,
`a series of data packets may be linked together and delivered
`to a receiving device 40. In essence, device 40 receives
`indication that a linked list of data packets are required and
`successively targets each next packet in the list, i.e., targets
`an appropriate time slot under the time-division multiplex
`protocol, to collect the sequence of linked data packets and
`thereby build a data ?eld 400d of inde?nite length. Because
`advertising information need not be presented immediately
`upon collection by device 40, such large volume data
`transmissions, i.e., large volume data ?elds 400d such as
`digitized sound data, may be downloaded into devices 40
`during low system activity times, e.g., at night when system
`demands are low.
`FIG. 5 illustrates a command set employed in the manipu
`lation of devices 40. In particular, a set of commands
`delivered by way of paging data packets drives each device
`40 in the downloading of advertisement records 400 and
`management thereof including the triggering of advertise
`ment presentation. In FIG. 5, command set 500 includes a
`STORE command 500a. STORE command 500a is associ
`ated with an index parameter and a data parameter. As may
`be appreciated, the index parameter value is written into the
`index ?eld 400a of the associated new record 400 and the
`data parameter is written into the data ?eld 400d of the new
`associated database record. Furthermore, the data parameter
`of STORE command 500a may be of signi?cant length, i.e.,
`may be digitized sound, and therefore necessarily collected
`through a sequence of linked paging system data packets.
`Accordingly, the data parameter of STORE command 500a
`can be actual data or an address pointer to the beginning of
`a linked list of paging system data packets containing data
`representing advertising information.
`DELETE command 50% and its index parameter causes
`deletion from the memory resource 90 of the record 400
`stored under the associated index.
`PRESENT command 5000 and its index parameter cause
`device 40 to present the associated advertisement
`information, i.e., queue for presentation the record 400
`bearing the associated index.
`SEI‘ CONDITIONS command 500d updates the condi
`tion list 400b in a speci?c record 400. Thus, SEI‘ CONDI
`TIONS command 500d and its index parameter identify a
`record 400 to be modi?ed, and a data parameter contains a
`new condition list ?eld 400b for the record 400 to be
`modi?ed. As may be appreciated, in the event of a lengthy
`new condition list ?eld 400b, the data parameter of com
`mand 500d can be a pointer to a sequence of linked paging
`system data packets. In any event, SEI‘ CONDITIONS
`command 500d allows modi?cation of a condition list ?eld

`4001: without requiring downloading of the entire record
`400, i.e., without requiring retransmission of the data ?eld
`400d of an existing record 400.
`RECORD ON command 500e and RHIORD OFF com
`mand 5W provide a mechanism for recording directly, i.e.,
`digitizing, the voice broadcast 22 at the receiving device 40.
`Thus, RECORD ON command 500a and its index parameter
`begin recording of the voice broadcast 22 and storing the
`digitized sound data in the data ?eld 400d of a new record
`400 having in its index ?eld 400a the value of the RECORD
`ON command 500e index parameter. Recording of voice
`broadcast 22 continues until device 40 receives the
`RECORD OFF command 500f. In this manner, downloading
`a massive volume of digitized sound data by way of data
`broadcast 26 is avoided because device 40 ef?ciently cap
`tures and digitizes the voice broadcast 22 and establishes a
`record 400 therefor with an ability to present such audio
`advertisement multiple times.
`FIG. 6 illustrates by ?ow chart generally the process of
`collecting advertising information at device 40, i.e., pro
`gramming for data radio 62 and microprocessor 60. In FIG.
`6, advertising information capture, store, and management
`procedures begin at block 600 where data radio 62 activates
`and captures a paging data packet. In decision block 602,
`data radio 62 compares the address of the captured paging
`data packet with its address to determine a match. In no
`match occurs. indicating the captured packet was not
`addressed to this data radio 62, processing branches to other
`unrelated programming. If a match does occur, indicating
`the captured paging data packet is addressed to this data
`radio 62, then processing advances to block 604 where data
`radio 62 transfers the captured paging data packet to micro
`processor 60 for further processing.
`Continuing to block 608, microprocessor 60 interrogates
`the just received data packet to determine whether it is a
`member of command set 500. If the data packet is not a
`member of command set 500, then processing branches to
`decision block 610 where microprocessor 60 determines
`whether the data packet is a member of a linked list of data
`packets. If the data packet is not a member of a linked list,
`then processing branches through block 612 where the next
`data packet is targeted. As may be appreciated, processing in
`block 612 includes appropriate interaction between micro
`processor 60 and data radio 62 to cause, when necessary,
`data radio 62 to target a speci?c time slot under the paging
`system protocol. Following block 612, processing returns to
`block 600.
`Returning to block 610, If the captured data packet is a
`member of a linked list of data packets, then processing
`branches through block 614 where the data portion of the
`captured data packet is appended to the appropriate ?eld of
`an existing data record 400. Processing then continues to
`block 612. Returning to block 608, if the captured data
`packet is a member of cormnand set 500, then processing
`branches through block 616 where microprocessor 60
`executes the command whereafter processing advances to
`block 612. In this manner, device 40 responds to command
`set 500 and collects lengthy condition list ?eld 40% or data
`?eld 400d for incorporation into data records 400.
`FIG. 7 further details programming illustrated in the
`EXECU'I'E cormnand block 616 of FIG. 6. In FIG. 7,
`program control is organized generally as a switch structure
`with each case branching in response to a given member of
`command set 500. Processing begins in decision block 700
`where the STORE command 500a is detected. Upon detect
`ing the STORE command 500a, microprocessor 60 creates
`
`8
`in block 702 a new data record 400 with associated index,
`i.e., the index value provided as the index parameter to
`STORE command 500a. Continuing to block 704, micro
`processor 60 stores ‘the data parameter of command 500a in
`the data ?eld 400d of the newly created record 400. As may
`be appreciated, if the data parameter of STORE command
`500a represents a linked list of data packets, then micro
`processor 60 prepares to later append such linked data
`packets to the data ?eld 400d as indicated at decision block
`610 of FIG. 6. Command execution tm'minates following
`block 704.
`Decision block 706 detects presentation of the DELEI‘E
`command 500k. Upon detecting the DELEI'E command
`500b, microprocessor 60 removes in block 708 the associ
`ated advertisement record 400, i.e., that record 400 having
`an index ?eld 400a matching the index parameter of the
`detected DELETE command 5001). Command execution
`terminates following block 708.
`Decision block 710 detects the PRESENT cormnand 500.
`Ifthe PRESENT command 500 is detected, then processing
`branches through block 712 where microprocessor 60
`queues for presentation the corresponding advertisement,
`i.e., provides to the advertisement presentation block 104 the
`index value provided by the index parameter of PRESENT
`command 5000. Command processing terminates following
`block 712.
`Decision block 714 detects the SEI‘ CONDITION com
`mand 500d, with processing then branching through block
`716 where microprocessor 60 replaces the condition list
`40% of the record 400 corresponding to the index parameter
`provided with SEI‘ CONDII'ION cormnand 500d, i.e.,
`writes the data parameter of command 500d into the con
`dition list 40% of the associated record 400. As may be
`appreciated, if the data parameter of command 500d is a
`pointer to a linked list of data packets, then microprocessor
`60 appropriately gathers such linked list of data packets and
`successively writes each data packet into the condition list
`?eld 4001; of the associated record 400.
`Decision block 718 detects presentation of the RECORD
`ON command 500d. In response, processing in block 720
`creates a new record 400 with the associated index value,
`i.e., a value c
