`
`CROSS REFERENCE T0 RELATED APPLICATION
`
`This application claims the benefit of United States Provisional Patent Application
`
`No. 60/270,463, filed February 20, 2001, which is hereby incorporated by reference
`
`herein in its entirety.
`
`FIELD OF INVENTION
`
`Our invention relates to radio systems and methods. In particular this invention
`
`10
`
`relates to enhanced radio reception and processing features, utilizing multiple radio
`
`receivers, digital storage of radio content, independent control of radio reception and
`
`playback, listener profiles, and two—way communication features.
`
`BACKGROUND OF THE INVENTION
`
`15
`
`20
`
`25
`
`Radio is a very popular entertainment source today. It is used in many locations —
`
`in the home, in the automobile, at the office, and on the go. Sources available today
`
`include broadcast (AM and FM), Internet, and satellite. However, radio functions have
`
`been fairly constant for years.
`
`New technologies have become available in recent years. These include less
`
`expensive tuners, less expensive memory, and better quality analog to digital conversion.
`
`These technologies make possible an enhanced radio system.
`
`Some improvements have been made in television systems recently. Personal
`
`video recorders, such as those manufactured by TiVo, allow a user to easily record a
`
`television program, and also provide VCR—like controls for television programs. For
`
`example, see US. Patent No. 6,259,441 (2001) to Ahmad et al., "Display pause with
`
`elastic playback," US. Patent No. 6,327,418 (2001) to Barton, "Method and apparatus
`
`implementing random access and time—based functions on a continuous stream of
`
`formatted digital data," and US. Patent No. 6,233,389 (2001) to Barton et a1.,

`PCT/US02/05039
`
`"Multimedia time warping system". However, these types of improvements have been
`
`optimized for the needs of the television viewer. For instance, this prior art focuses on
`
`improving the viewing of specific television programs.
`
`Radio listeners typically have different needs than television Viewers. For
`
`example, television viewing typically happens in a fixed environment in a home, while
`
`radio listening often happens in varied, often mobile, environments. People may listen to
`the radio in a shower. People often listen to radio in a car, or carry a radio on their person
`as they pursue other activities. A television Viewer may sit and watch a program through ‘
`
`its completion. A radio listener more often listens casually while pursuing other
`
`activities, and may often switch between stations based on hearing a short duration item,
`
`such as a song, commercial, or traffic/weather report. Program schedules are quire
`
`important to television viewers, but are rarely used by radio listeners.
`
`A system is needed that allows a radio listener to better control the audio content
`
`she hears. For example, a listener may need a way to easily back up and hear something
`
`again. This might include, for example, repeating a piece of information from a weather
`
`report or a traffic report, a phone number or other item in an advertisement, a favorite
`
`song, or information about a radio contest.
`
`A radio listener may also need a way to pause the radio content while doing
`
`something else. For example, a listener in a car may wish to pause a song while
`
`concentrating on traffic or talking to someone else in the car. After resuming the song,
`
`the listener may listen to the remainder of the song and then may subsequently wish to
`
`fast-forward through commercials to catch up to the real-time broadcast.
`
`US Patent No. 5,345,430 (1994) to Moe, "Recovery recorder system, particularly
`
`commercial radio/TV broadcast recovery recorder system," discloses continuously
`
`recording the last few minutes of a program being monitored to a short—term memory, and
`
`transferring it, on operator command, to a long-term storage media. US. Patent No.
`
`5,448,534 (1995) to Okada, "Radio with recording and reproducing function," discloses
`
`detecting a desired program and starting a recording device to record the program.
`
`However, this prior art requires a user to select a specific radio station or program to
`
`10
`
`15
`
`20
`
`25
`
`30
`
`record.
`
`Because digitized audio content requires much less memory than digitized video
`
`content, it is less expensive to store a significant amount of radio content. A radio tuner
`
`2
`
`Petitioner Hyundai EX-1007, 0004
`
`Petitioner Hyundai Ex-1007, 0004
`
`

`

`W0 02/067447
`
`PCT/US02/05039
`
`is also less costly than a television tuner, so a system that monitors multiple radio stations
`
`at once is quite feasible. Because a radio listener is quite likely to be interested in the
`
`programming on multiple radio stations at the same time, a system with multiple tuners
`
`and significant but inexpensive memory is also quite useful.
`
`For example, a system is needed that would allow auser to switch between
`
`multiple favorite radio stations and rewind to the start of an interesting piece of content
`
`that may have been missed, such as a favorite song or a traffic report. Because detailed
`
`radio content schedules are not typically published in advance, it would also be useful to
`
`have a system that allows a user to identify items of interest, that informs the user when
`
`an item of interest is being broadcast on another station, and that allows the user to switch
`
`to that station and rewind back to the start of the item.
`
`Since radio listeners frequently sing along with favorite tunes in locations such as
`
`the shower and the car, a user may wish to sing along with a radio in a karaoke mode.
`
`A system is also needed to recommend a set of radio stations to a user. This
`
`would be particularly useful for traveling users, or users new to an area. Such a system
`
`might allow a radio listener in a rental car or hotel to automatically search a database of
`
`radio stations and find one or more that matches his tastes. A driver on a long trip may
`
`need a system that automatically monitors available radio stations and compares the
`
`content with his likes.
`
`Traveling listeners may also need a system to inform them of venues and events in
`
`an unfamiliar local area. For example, a listener may be interested in finding out about
`
`concerts, celebrity appearances, radio station events, concert venues, music stores, and the
`
`like.
`
`Radio listeners often listen in multiple environments — in different rooms of the
`
`house, in the car, in the office, and using a portable system. These listeners need a system
`
`that allows them to use the advanced radio features in all of these environments. They
`
`need a way to transfer information, such as radio presets, favorite songs, and favorite
`
`artists, from one environment to another. They need a way to update the functionality of
`
`the radio without having to purchase a new system. They need a system that allows
`
`downloading of favorite songs into a radio.
`
`Radio listeners also need an Internet environment to coordinate their enhanced
`
`radio listening activities. These activities might include finding out about music,

`
`PCT/US02/05039
`
`shopping for music related products, and finding out about radio stations. They may also
`
`need a system that allows them to manage the information used in an enhanced radio
`
`system, such as favorite stations, artists, and songs.
`
`A radio listener may also need a way to more easily respond to radio content. For
`
`example, a listener may wish to respond to an ad, enter a radio contest, call in to a radio
`
`talk show, or make a song request. The user may need a system that allows a telephone to
`be used with the radio system.
`
`A radio listener also needs a way to more easily communicate with other radio
`
`listeners. A listener may Wish to send information heard on the radio to another person.
`
`This information may include an invitation to or information about a concert or other
`
`event, a link to a radio station or radio show, a song heard on the radio, or other radio-
`
`related information.
`
`In addition to radio listeners, radio service providers may also benefit from our
`
`invention. Radio service providers need a system that allows them to monitor the habits
`
`of their listeners' demographic profile such as which commercials they repeat, which
`artists they favor, etc., as well as what enhanced radio features their users may access.
`
`SUMMARY
`
`These and other advantages are provided by our enhanced radio system. A main
`
`aspect of our invention is simultaneously storing the content from multiple radio
`
`receivers. Another aspect of our invention is allowing the multiple receivers to be tuned
`
`to radio stations based on stations chosen as favorites by the listener, based on recently
`
`played stations, and based on scanning for new stations. Another aspect of our invention
`
`is allowing a listener to quickly select output from the stored content of any of the
`
`receivers. A further aspect is allowing a listener to pause, resume, or skip backwards or
`
`forwards in time within any of the stored content, including allowing a listener to hear
`
`radio content broadcast prior to switching to a station. Another aspect of our invention is
`
`allowing a listener to record radio content, or download other audio content, and quickly
`
`access it later. Yet another aspect of our invention relates to providing a karaoke feature,
`
`with the removal of vocal tracks and the display of lyrics for broadcast songs.
`
`Other aspects of our invention relate to the collection and use of user preferences.
`
`A listener may be allowed to rate specific content or groups of content. The system may

`
`recognize and notify the listener of preferred content when it is broadcast on a station that
`
`the listener is not currently listening to. The system may recognize and automatically
`
`skip over disliked content when it is played on a station the user is listening to. The
`
`system may recommend radio stations to a listener. The system may recommend local
`
`events and facilities to a listener.
`
`Still further aspects of our invention relate to communications. Our invention
`
`may interact with a mobile or stationary telephone, using the radio's sound system, and
`
`may automatically pause or mute the radio during calls. Our invention may allow a
`
`listener to send and receive messages with another listener, including recorded radio
`
`content. Our invention may allow a listener to easily respond to radio content, such as
`
`contests, requests, call-in shows, pledge drives, etc. A listener can purchase CDs, concert
`
`tickets, and other products and services. Our invention may include an Internet website,
`
`with additional radio features. And our invention may provide monitoring of listener
`
`usage and habits to provide a ratings service.
`
`Other aspects of our invention relate to portability and configurability. Our
`
`enhanced radio system may be used at home, at the office, in the shower, on the go, in the
`
`car, on the boat, or in any other environment. It may be used in multiple environments.
`
`And user preferences and profiles may follow the listener in any of these environments,
`
`from radio to radio.
`
`This system can tune in one or more radio sources, such as broadcast radio,
`
`satellite radio, Intemet radio, short-wave radio, and radio scanners. The system may
`
`employ multiple receivers (e.g., antennas, tuners, etc), so that the system can monitor
`
`multiple radio stations at the same time. If any of the input signals is analog, it is
`
`digitized, and then the digital radio signal is stored in memory.
`
`Our invention also includes a controller, such as a microprocessor with program
`
`memory, to control the functions of the receivers, digitizers, and other parts of the system.
`
`A user can control the functions of the controller using an input device such as a remote
`
`control, a voice control, a front panel control, etc. There may also be a display to provide
`
`visual feedback to the user.
`
`Digital audio signals are retrieved from the memory on command from the user,
`
`' converted to analog signals, and sent to an output device, which may include an amplifier,
`
`speakers, and the like.

`
`Our enhanced radio system may be operated in a home or office, in a shower, in a
`
`car, truck or boat, or as a portable system carried or worn by the user. The system may
`
`also be configurable so that it can operate in multiple environments by, for example,
`
`allowing the user to use different input controls and different audio output devices.
`
`Our invention may provide a number of features beyond what are provided by
`
`standard radios today. For example, the system may allow the user to stop, rewind, fast—
`
`forward, and resume playing the radio, While continuing to record the radio input. For
`
`example, the user may rewind to replay a segment of interest, and then fast-forward to
`
`continue playing the broadcast audio.
`
`10
`
`The system may allow the user to skip-back or forward a preset interval, such as
`
`30 seconds. This may allow, for example, the user to skip over commercials in recorded
`
`audio.
`
`The system may provide different speed playing. When playing at reduced or
`
`increased speeds, it may provide frequency compensation so that the sound is
`
`15
`
`recognizable.
`
`Our invention may allow the user to record a portion of the radio input in memory
`
`for later playback. Recording may be based on impulse/command, based on a published
`
`schedule of radio content, based on a specific time/station, or on other criteria.
`
`Recordings may also be stored or transferred to an external analog or digital storage
`
`20
`
`device.
`
`The system may provide preset stations. Stored radio programs may be available
`
`as preset stations separate from the stations from which they were recorded.
`
`This invention may allow identification of specific pieces of audio content, such
`
`as songs and commercials. The system may allow the user to indicate (e. g., by pressing a
`
`button or other control) that a piece of content has begun or ended. The system may also
`
`recognize the start or end of content based on silence, changes in audio characteristics, or
`
`other cues in the audio. For example, the system may measure the frequency and power
`
`content of the audio signal, and recognize new content based on changes in harmonic
`
`content, rhythmic content, etc.
`
`The system may recognize a piece of content that has previously been identified.
`
`The user may be allowed, for example, to name a piece of content, and to identify the
`
`25

`
`

`

`W0 02/067447
`
`PCT/US02/05039
`
`type of content (song, commercial, talk, etc.) The system may create a unique signature
`
`of the audio signal of a particular piece of content, and use that signature to recognize that
`
`content on future occasions. Signatures may be created separately in an external system
`
`and downloaded from the external system into the enhanced radio system. Also,
`
`information sent either in-band with the audio or in a separate channel (e.g., over the
`
`Internet) may identify the content currently being broadcast. The system may include a
`
`separate receiver to receive the separate information signal.
`
`The system may allow the user to rate a piece of content. For example, the user
`
`may be able to specify a like or dislike for a particular song or commercial, or to indicate
`
`a level of interest. The user may also to be able to rate a specific musical artist, station,
`
`radio show, and other sets of content. The system may be configured to skip over
`
`undesirable content.
`
`Our invention may include multiple radio inputs. The radio signals from each
`
`input may be simultaneously digitized and recorded. For example, the user may be
`
`allowed five favorite stations in a system with six tuners. In this way the system may
`
`always be recording the favorite stations and the most recently tuned station in addition to
`
`whatever station the user is currently listening to. The user may tune to any of the
`
`favorite stations at any time, and be able to rewind to content that may have been
`
`otherwise missed. For example, the user could tune to a station in the middle of a song
`
`and immediately rewind to the beginning of the song, as the audio from the song has
`
`previously been digitized and stored to memory. Similarly, the user could rewind to hear
`
`a traffic or weather report that was missed, clues and phone number for a radio contest,
`
`details in an ad of interest, or any other content of interest. Our invention may also
`
`provide a scan feature, briefly playing audio from the available radio stations in sequence,
`
`allowing the user to stop when something of interest is heard, and allowing the user to
`
`skip-back to the start of the item of interest.
`
`The system may provide an alert when content of interest is being played on a
`
`different station. For example, when a favorite song or artist is played on a station other
`
`than the current station, the system may notify the user, who could tune to that station and
`
`rewind to the beginning of the song. The system may provide a single button to tune to
`
`the station with the most recent content of interest notification. Alternatively, the system
`
`may automatically change to the station with the content of interest, and may
`
`automatically rewind to the start of the content.

`
`The system may compare information about the user's likes and dislikes with
`
`information about radio stations to create recommendations. The user may enter
`
`information about her likes and dislikes, or this information may be obtained
`
`automatically by monitoring the content she listens to. For example, a recommendation
`
`may be provided in any of the following ways:
`
`there may be a list of stations that the user
`
`can choose from; the system may automatically set one or more presets based on the
`
`recommendations; or the system may automatically tune to the recommended stations:
`
`Our invention may obtain information about stations in a number of ways. For
`
`example, the information may be sent in-band with the radio signal or delivered
`
`10
`
`concurrently but over a separate communications channel. Information may be
`
`downloaded into the system from a database of station characteristics using, for example,
`
`a wireless Internet connection. Such a database may include, for example, stations,
`
`format, geographical reach, program schedules, etc. The system may monitor the content
`
`of the prospective station and compare its content with the signatures of the content the
`
`15
`
`user has rated.
`
`Radio recommendations might be especially usefiil to a traveling user who is not
`
`familiar with local stations. For example, these features may be built into a portable
`
`enhanced radio system. A rental car radio may be equipped with an enhanced radio
`
`system including these features. A user may insert a smart card or other device into the
`
`radio to indicate preferences, and the system may automatically determine the best
`
`matching local stations. Such a system may, for example, set the presets, automatically
`
`tune, record, or otherwise make the recommended content available to the user. The
`
`system may include a global positioning system (GPS) unit to determine the user’s current
`
`location as an index into a database of radio stations, and then scan the database for
`
`stations matching the user's criteria. The system may alternatively scan radio stations
`
`using a tuner other than the one the user is currently listening to, and compare the content
`
`on each station with signatures indicating the user's preferences.
`
`The system may provide automatic notification of local concerts, performing artist
`
`appearances, signings, radio station events, weather, and other events of interest. This
`
`information may be of interest to all types of users, including those users who are
`
`traveling in an unfamiliar region. Similarly, the system may provide information about
`
`local music venues, stores, and other facilities and businesses.

`
`Our invention may include a communications device, such as a radio frequency
`
`transceiver, modem, portable memory device, or networking equipment. This device may
`
`be used to allow the system to download a user's profile, download radio station data, and
`
`synchronize information between a user's different enhanced radio systems in different
`
`locations. The device may be used to update the software in the enhanced radio system,
`
`to download songs into the enhanced radio system, and to report usage information to a
`
`ratings service. The system may, for example, use the user’s telephone or mobile phone
`
`as a link to access remote data.
`
`10
`
`15
`
`The user may have multiple enhanced radio systems, to be used in different
`
`environments. All of the user's various enhanced radio systems may be synchronized.
`
`For example, likes, dislikes, and presets may be exchanged between the systems.
`
`Synchronization may be Internet based, for example, by allowing the user to upload data
`
`from an enhanced radio system to a web site, and to download data from the web site to
`
`another enhanced radio system.
`
`The user may access an enhanced radio web site using a web browser. The web
`
`site may provide features such as a shopping for CDs and other products, concert
`
`information and ticket buying, trivia questions, contests, music information databases,
`
`etc. The web site may provide a computer desktop radio feature, allowing the user to
`
`listen to radio on a personal computer while connected to the Internet. The Internet
`
`20
`
`website may also have advertisements, which may be based on user preferences, either as
`
`determined by the web site, or as uploaded from an enhanced radio system.
`
`The web site may also include access to radio station databases and schedules,
`
`which may be downloaded to an enhanced radio system. Data may be loaded into a
`
`mobile phone or personal digital assistant, which may be used to load information into an
`
`25
`
`enhanced radio system in, for example, a rental car. Data may include such information
`
`as station names and frequencies, formats, play lists, signatures, schedules, geographical
`
`reach, etc.
`
`A two-way communication feature may be included as part of an enhanced radio
`
`system and may provide a number of advantages. For example, the user may be able to
`respond directly to radio advertisements without having to telephone, or the system may
`
`30
`
`auto-dial a mobile telephone to a phone number included in the advertisement. Similarly,
`
`the user may respond to contests and call-in shows, and make requests, either directly

`
`using the two-way communication feature, or the system may auto-dial the radio station
`
`to support these features. The auto-dialed phone number may be hand-entered by the
`
`user, part of the radio station database, or included in information sent as part of or
`
`separately from the radio signal. In addition, the user may buy CDs, buy concert tickets,
`
`participate in live chats, and other features. The user may select these features using a
`
`voice command or other types of controls.

`
`The system may also incorporate telephone functions. The system may connect
`
`with a mobile telephone or a wired telephone service. The system may provide telephone
`
`audio using the enhanced radio's voice input and audio output. The system may
`
`automatically pause or mute the radio audio while a call is in progress.
`
`The system may allow one enhanced radio user to send an instant message or
`
`other electronic message to another enhanced radio user. The message may, for example,
`
`be text, voice, or a combination. The message may include all or part of content from a
`
`radio station, such as a song. The message may be otherwise related to radio content, for
`
`example including a link allowing the recipient to easily tune to a specificstation or
`
`show. It may include, for example, a signature of a specific song. The message may be,
`
`for example, an invitation to a concert or other event.
`
`The system may also provide a karaoke mode. In this mode,‘it may remove the
`
`vocal component from the audio signal as it is being played. It may also display lyrics of
`
`20
`
`a song as it is being played.
`
`Information may be loaded into an enhanced radio system by any number of
`
`methods. For example, information may be received (and sent) over a wireless link, such
`
`as a wireless telephone or paging link. Information may be loaded via prerecorded media,
`
`such as a compact disk or digital versatile disk. Information may be loaded from a smart
`
`25
`
`card, PC Card, or other portable memory device. Information may be received and sent
`
`via a telephone link. Information may be exchanged over the Internet. Information may
`
`be entered by hand.
