`
`ABSTRACT
`(57)
`A broadcast response system provides, e.g., a radio broadcast
`listener with the ability to obtain media content such as music
`or speech while listening to the radio. The user can respond to
`items in the radio broadcast such as advertisements, fund
`raising drives, or interactive listener polls during the broad(cid:173)
`cast. Data such as song title and artist, author or publisher and
`the IP address forthe location where the digital version of the
`content is stored, can be transmitted using, e.g., the RBDS/
`RDS data stream. A reference number representing song title
`and artist, author or publisher and the IP address for the
`location where the digital version of the content is stored can
`also be employed for ease of implementation. This reference
`number can reside in a lookup table to be accessed by broad(cid:173)
`cast response server.

`Emergency Alert System (EAS) communication messages.
`An extensive description of the RBDS standard is available
`through the National Association of Broadcasters and the
`25 National Radio Systems Committee.
`A similar standard used in Europe is the European Radio
`Data System (RDS).
`Broadcasters using the RBDS standard can distribute infor(cid:173)
`mation to a large number of users. However, the standard does
`30 not allow individual users to respond to the broadcast infor-
`mation.
`Currently, users listening to the radio or watching televi-
`sion may particularly like a song or program that they would
`like to purchase. While stations using RBDS/RDS may pro(cid:173)
`vide a user with the station call letters or the name of the song
`currently being broadcast, the user has no way to purchase the
`media at that point. Instead, the user must write down or
`remember the identifying information and then go to a store
`or online retailer to purchase the media. Not only is this
`inconvenient, but the user may forget the name of the song or
`not be able to find a store that sells the song. Additionally, the
`information provided by the radio station may not be enough
`to sufficiently identify the song. For example, the user may
`have the song title, but not the artist name, album name, or
`45 other necessary identifying information. Some material, such
`as editorial news broadcasts or live events, may not be avail(cid:173)
`able for purchase or may be difficult to find. Radio stations
`often have fund raising drives or listener surveys that require
`a listener to call the station or respond within a limited time.
`50 These same problems also apply to television and other forms
`of broadcast media.
`
`1. Field
`This invention relates to processing responses to a broad(cid:173)
`cast.
`2. Description
`From the early days of FM broadcast transmission, stations
`have included ancillary signals such as background music or
`reading services for the blind along with a main carrier signal.
`The idea of transmitting data along with the main carrier
`signal caught on, and now many broadcast radio services
`either transmit an ancillary data signal or are developing a
`method to do so. The most current and widely used data 35
`transmission standard is the United States Radio Broadcast
`Data Systems ("RBDS") standard.
`The RBDS standard, published by the National Radio Sys(cid:173)
`tems Committee and sponsored by the Electronics Industry
`Association and the National Association of Broadcasters, 40
`describes a system for broadcasting a variety of program(cid:173)
`related information on a subcarrier of a standard FM broad(cid:173)
`cast channel. The RBDS standard teaches a system for trans(cid:173)
`mitting station identification and location information, as
`well as time, traffic and miscellaneous other information.
`The RBDS standard was designed to allow stations to send
`information such as call letters, station format, traffic alerts
`and scrolling text messages to compatible radios.
`Many stations installed RBDS encoders through a program
`encouraged by the FCC in the early 1990's that provided
`encoders at no charge. Radio stations that did not participate
`in this "RBDS Roll-Out" can still obtain encoders at com(cid:173)
`petitive prices.
`RBDS encoders generate what is known as a "subcarrier"
`that modulates along with an FM station broadcast signal and 55
`can be demodulated by special decoders. The RBDS uses a
`subcarrier frequency of 57 khz. Commercially available
`RBDS encoders usually accept information via either serial
`or parallel data ports and format the information into the
`appropriate RBDS block type.
`The RBDS data signal is a specially encoded text stream
`containing up to 32 repeating data "groups" transmitting at
`1187 .5 bits/second. The RBDS data signal does not require
`inclusion of all potential data group blocks of both repeating
`and unique data. One embodiment includes using one of 65
`several groups that are designed for data transmission func-
`tions.
`
`SUMMARY
`
`The present invention solves these and other problems by
`providing a system that allows an individual user to respond
`to a data broadcast. In one embodiment, an Automatic Pur(cid:173)
`chase System (APS) provides a radio broadcast listener with
`the ability to conveniently purchase media content such as
`60 music or speech while listening to the radio. Additionally, the
`user can respond to items in the radio broadcast such as
`advertisements, fund raising drives such as those conducted
`by public radio, or interactive listener polls during the broad-
`cast.
`In one embodiment, the user establishes a "Creative con(cid:173)
`tent" purchasing account with a wireless carrier. In one
`embodiment, a personal URL (web address) is assigned to the
`
`

`user to allow the user, for example, to monitor account activ(cid:173)
`ity, enable or disable APS software downloads, display pre(cid:173)
`miums offered by sponsors, and manage and track content or
`APS purchases using a Technology Enabled Radio (TER) or
`a personal computer.
`In one embodiment, the user makes routing choices
`between the TER or the web account for content. In one
`embodiment, the user selects the compression type, such as
`MP3, RA, Liquid Audio etc.
`In one embodiment, each broadcaster has an RBDS/RDS
`or similar technology enabled server onsite to, for example,
`generate RBDS/RDS or equivalent code for inclusion in the
`broadcast, validate and route purchase information to the
`user's wireless carrier for billing, monitor online sales trans(cid:173)
`actions for data mining, or route validated purchases to
`licensed creative content providers.
`In one embodiment, radio hardware can include, for
`example, RBDS/RDS or equivalent decoder capability (e.g.,
`in an internal chip with APS code); flash card slot and record(cid:173)
`ing ability; or storage of multiple items such as artist name, 20
`song title, IP address of creative content provider, and time
`stamp for delayed purchase (e.g., in an internal chip withAPS
`code).
`In one embodiment, the system uses the RBDS/RDS to
`send a data stream in combination with a broadcast signal for 25
`identifying music or speech content available for purchase. A
`broadcast organization participating in theAPS system is able
`to respond to requests for purchases placed by users who
`either click a button or issue a voice command to the radio at
`the time of the content was broadcast, at a later time by 30
`scrolling through the play list stored in theAPS module in the
`radio then selecting one or more items for purchase from the
`list stored in the radio, or by accessing a private web account
`via the Internet and downloading content to the personal
`computer. In one embodiment, purchases are made by saving 35
`requests for selected items for purchase on a flash card or
`storage technology and transferring that data to a personal
`computer for purchase through the Internet at a later time.
`Data such as song title and artist, author or publisher and
`the IP address for the location where the digital version of the 40
`content is stored, can be transmitted using the RBDS/RDS
`data stream. A reference number representing song title and
`artist, author or publisher and the IP address for the location
`where the digital version of the content is stored can also be
`employed for ease of implementation. This reference number 45
`can reside in a lookup table to be accessed by the APS server
`software on a Data Server located at the broadcast site, a
`remote site or both for purposes of redundancy. Transmission
`of purchase requests from a Technology Enabled Radio
`(TER) is provided via wireless transmission, or by accessing 50
`the Internet using a personal computer or through a cellular or
`wireless phone. In one embodiment, activity of each sale
`using the above system is tracked for the purposes of aggre(cid:173)
`gating data or "Data Mining" for sale to interested parties
`such as trade publications and record companies.
`Portable radios can come equipped with a voice interface
`or a purchase button, a flash card or storage device and a port
`for connecting the radio to the personal computer such as a 9
`pin serial, USB or wireless networking technology.

`
`DETAILED DESCRIPTION
`
`The present invention solves various problems in the prior
`art by providing a system that allows an individual user to
`respond to a data broadcast. In one embodiment, an Auto(cid:173)
`matic Purchase System (APS) provides a radio broadcast
`10 listener with the ability to conveniently purchase media con(cid:173)
`tent such as music or speech while listening to the radio.
`Additionally, the user can respond to items in the radio broad(cid:173)
`cast such as advertisements, fund raising drives such as those
`conducted by public radio, or interactive listener polls during
`15 the broadcast.
`One of ordinary skill in the art will recognize that there are
`various forms of media that can be broadcast. Where a spe(cid:173)
`cific type of media is used in the following examples, it is for
`demonstration purposes only and the examples should not be
`limited in that regard. Some examples of the various types of
`media can include music, songs, speech, text, video, etc.
`FIG. 1 illustrates one embodiment of a system that allows
`a user to respond to a data broadcast. FIG. 1 shows a radio
`station 140 that broadcasts information to a radio receiver
`100. The radio receiver 100 has a control interface 116 that
`allows a user to initiate a purchase of music or products based
`on the radio station broadcast.
`The terms RBDS/RDS are used throughout this document,
`but it should be understood other data standards can also be
`used. In one embodiment, the radio receiver 100 comprises a
`Radio Frequency (RF) Demodulator Section 102, a RBDS/
`RDS Decoder 106, a RBDS/RDS function control interpreter
`104, an audio demodulator amplifier section 108, a scrolling
`display 110, an Internet Download Director 112, a local
`memory device 114 and the control interface 116. Addition(cid:173)
`ally, the receiver 100 provides for audio output by transmit-
`ting an audio signal 128 from an audio demodulator amplifier
`section 108 to the speaker 118.
`In one embodiment, the RF Demodulator Section 102
`splits the signal into an audio signal and a data signal, with the
`data signal provided to the RBDS/RDS decoder 106 and the
`audio signal provided to the audio demodulator amplifier
`section 108. The RBDS/RDS decoder 106 parses the data
`signal from the RF Demodulator Section 102 and transmits
`the data to the RBDS/RDS Function Controller 104, the
`Scrolling Display 110, and the Internet Download Director
`112.
`The RBDS/RDS Function Controller 104 handles codes
`124 sent using the RBDS/RDS standard. The codes 124 can,
`for example, include a Program Service name (PS), a Pro(cid:173)
`gram Type (PTY), a Program Identification (PI), a Traffic
`Program (TP), a Traffic Announcement (TA), etc.
`In one embodiment, the data is converted to an audio signal
`played on one or more speakers for the user to hear. A 64
`55 character radio text message can be transmitted in five sec(cid:173)
`onds under the RBDS standard, where a Type 2A group with
`4 characters is transmitted 3.2 times a second.
`In one embodiment, a pointer to an Open Data Applications
`(ODA) group is transmitted in a Type 3A group. The pointer,
`60 16 message bits and 16 bit identifier (AID) are transmitted
`once a second.
`In one embodiment, an ODA group with 37 usable bits is
`transmitted once a second during the broadcast of a "tagged"
`program. The ODA group can contain, for example, a song or
`65 commercial campaign identification.
`In one embodiment, the scrolling display 110 receives
`display data 122 from the RBDS/RDS Decoder 106. The
`
`

`

`Case 6:20-cv-01131-ADA Document 1-5 Filed 12/11/20 Page 13 of 18
`
`US 8,903,307 B2
`
`5
`display data 122 can include information such as the program
`service name and program type, or it can include radio text
`information or messages displaying purchase options.
`Additionally, the RBDS/RDS Decoder 106 provides data
`to the Internet Download Director 112 that includes instruc(cid:173)
`tions for the location of downloadable audio. For example, a
`radio station 140 can broadcast data regarding the current
`song that is playing, such as the song name, artist, album
`name, and year the song was recorded. The radio station 140
`can also broadcast information providing a location where the 10
`song, editorial news broadcast, collection of songs, or other
`program material can be downloaded or purchased, and the
`purchase price for the song.
`In one embodiment, a user can place an order to download
`a song using the control interface 116. The control interface 15
`116 provides a download command signal 126 to the Internet
`Download Director 112. The Internet Download Director 112
`can then provide download instructions such as, for example,
`the location of the file for download and the security proce(cid:173)
`dures required for access. The download information is then
`transmitted over, for example, a wireless internet connection
`156 to the authentication and billing system 152. The authen(cid:173)
`tication and billing system 152 verifies the customer infor(cid:173)
`mation and determines whether the customer account can be
`debited for the cost of the order. The authentication and bill(cid:173)
`ing system 152 then provides an approval signal 168 indicat(cid:173)
`ing whether the purchase was approved. The approval signal
`168 is transmitted to the purchase database server 150.
`Once the purchase is approved, the purchase database
`server 150 provides purchase and download authorization to 30
`the download server 154. The download server 154 can then
`transmit the requested material over a network connection
`158. In one embodiment, the material is transmitted using a
`wireless internet connection directly to the radio receiver 100.
`In another embodiment, the material is made available to a
`personal computer. In one embodiment, the material is sent
`using traditional mail or parcel services. The download server
`154 also communicates with the audio database and encoding
`server 144 to provide available sound database information
`164.
`The radio station 140 includes a radio automation or CD
`playback system 142, an audio database/encoding server 144,
`an FM transmission system 146 and a RBDS/RDS encoder
`148. The radio automation or CD playback system 142 can
`extract information about songs or a radio program from the 45
`station play list or by extracting information encoded on a CD
`or a CD-ROM. The playlist information is provided to the
`audio database and coding server 144. The playlist informa(cid:173)
`tion can include the song title, artist, cut or other information.
`The audio database/encoding server 144 matches the infor- 50
`mation sent from the radio automation system 142 with infor(cid:173)
`mation in the database. If there is an audio file available for
`download, the database/encoding server 144 formats the
`download information and sends it to the RBDS/RDS
`encoder 148. Corresponding information is uploaded to the 55
`purchase database server 150.
`The RBDS/RDS encoder 148 transmits the RBDS/RDS
`information using the
