In various embodiments, the present invention generally relates to identifying, collecting, and processing music-related content within a radio broadcast environment.
In-band on-channel (“IBOC”) digital radio technology can be used by AM (amplitude modulated) and FM (frequency modulated) radio stations to transmit audio and other data. IBOC is a hybrid method for simultaneously broadcasting digital radio and analog radio in the same frequency band by placing additional digital subcarriers in the sidebands of the AM or FM channel. Such hybrid radio technology allows a single radio station to simultaneously broadcast one or more different programs in addition to an initial program transmitted on the radio station's analog channel.
The trade-designated “HD Radio” system is one example of broadcast radio technology designed to permit a smooth evolution from analog amplitude modulation (AM) and frequency modulation (FM) broadcast radio signals to a fully digital in-band on-channel (IBOC) system. This system delivers digital audio and data services to mobile, portable, and fixed receivers. Broadcasters can continue to transmit analog AM and FM simultaneously with higher quality and more robust digital signals, coupled with allowing conversion from analog to digital radio while maintaining current frequency allocations.
The National Radio Systems Committee, a standard-setting organization sponsored by the National Association of Broadcasters and the Consumer Electronics Association, adopted an IBOC standard, designated NRSC-5, which sets forth the requirements for broadcasting digital audio and ancillary data over AM and FM broadcast channels. The standard and its reference documents contain detailed explanations of the RF/transmission subsystem and the transport and service multiplex subsystems. The “HD Radio” broadcast radio technology is an implementation of the NRSC-5 IBOC standard.
For users of digital radio technology, it can often be difficult to obtain a complete inventory of the music-related content that might be available in a given area or market of interest (e.g., geographic area) at a particular time. For example, analog radio stations which are not digitally broadcasting may broadcast programming for which certain elements such as artist name, song title, album title, or album artwork cannot be readily identified or determined. As a result, such missing elements cannot be properly displayed to users. Many currently available hybrid radio products provide inadequate coverage in many markets, because of these “holes” in the system. It would be advantageous to address these information gaps so that a more complete picture of the music-related content available in a given area of interest can be presented to consumers.
What are needed, therefore, are enhanced tools and techniques for processing music-related broadcast radio signals in a given area of interest to identify and address missing information elements in music-related content.
In various embodiments of the invention, enhanced tools and techniques are provided for processing music-related broadcast radio signals to identify and address missing information elements in music-related content. The processing involved with these tools and techniques can be leveraged to generate music-related content guides such as music guides for a given area of interest.
In one embodiment, a method is provided for processing music-related broadcast radio data. The method includes receiving, with multiple tuners, a plurality of broadcast radio station signals each at a predetermined frequency and a threshold signal level; identifying each radio station signal as an analog signal or a digitally broadcast signal in response to the identified radio station signals; obtaining a broadcast sample from at least one of the radio stations; identifying at least one music-related information element missing from the broadcast sample; obtaining at least one of the missing music-related information elements from at least one data external source; and, updating a data storage medium of a computer system with the obtained music-related information elements. The music-related information may include at least one of an artist name, a song title, an album title, or an image
In certain embodiments, the method may include generating a music guide in response to at least a portion of the obtained music-related information elements. The generated music guide may be communicated to at least one user access device. The obtained music-related information may be compiled in response to the selected area of interest, and the music guide may be generated in response to the compiled music-related information. The method may include selecting a radio broadcast area of interest and receiving the plurality of broadcast radio station signals identified within the selected area of interest.
Apparatus and system embodiments implementing the method and process aspects of the invention are also described herein.
In developing various embodiments of the present invention, the inventor has discovered that it can be challenging to achieve a complete understanding of the music-related content that might be available in a given broadcast radio area or market of interest (e.g., geographic area or frequency range). For example, all or a portion of certain music-related information elements such as artist name, song title, album title, album artwork, images, or other data cannot be readily identified or determined at various times and in various areas of interest. Accordingly, various tools and techniques offered by the invention can be configured and programmed to address these music-related information deficiencies or missing data elements and to generate a more complete list or guide representing music-related content available in a given area of interest. Those skilled in the art will appreciate that the processes, tools, and techniques described herein provide a way to identify various parts of music-related content a single time but for multiple users. In certain embodiments, certain aspects of music-related content may only need to be fingerprinted or downloaded one time, instead of needing to be identified or downloaded multiple times at each client device or on the receiver side of a system architecture.
Various embodiments of the present invention can be used in connection with IBOC digital radio technology or other hybrid methods for simultaneously broadcasting digital radio and analog radio. For example, the trade-designated “HD Radio” system can be used in connection with tools, techniques, processes, and apparatuses described herein. Alternatively, embodiments of the invention can be employed with other digital broadcast radio standards. For example, certain areas of the world have implemented Eureka-147 Digital Audio Broadcasting (“DAB”). Another example is Digital Radio Mondiale (“DRM 30”), which is a system designed primarily for shortwave radio communications. In another example, CDR, is a digital radio broadcasting standard and a type of IBOC system that operates in the FM band (e.g., 87 MHz to 108 MHz).
With reference to
In the example shown in
In the example shown, the digital broadcast radio processing system 104 includes one or more electronic computer processors 104A (e.g., servers) configured and programmed to perform various tasks and execute different kinds of computer-readable instructions within the system 104. In operation, the processor 104A may access a plurality of modules 104B-104E, which can be configured for specific tasks or functions performed by the system 104. In other aspects, one or more kinds of data storage media 104F may be provided in the system 104 to store data, documents, text files, analysis results, or a variety of other kinds of data and information related to broadcast radio signals. For example, a music guide generation module 104B may be programmed for generating a list or guide of available music programming selections available within a predetermined area or market of interest. The guide may include a variety of music-related information such as artist name, song title, album title, album artwork, or other data. The user communication module 104C may be configured for communicating data to one or more user access devices 108 through different types of communication media 106. Examples of user access devices 108 include radios, radio players, mobile devices, and many other kinds of computers or computing apparatus. In one embodiment, the user access device 108 may be equipped for accessing and communicating an “FM+” software application. A fingerprint processing module 104D may be programmed to communicate with one or more fingerprinting services 110. It can be appreciated that the fingerprinting service 110 can be accessed to identify data associated with an audio snippet or other types of broadcast samples. In certain embodiments, one or more other kinds of modules 104E may be provided, such as to receive data from an artwork or image retrieval service 112 to furnish image-related elements missing from certain music-related data, for example.
At step 208, the process can identify the radio station associated with the broadcast radio signal as an analog station or a digitally broadcast station in response to the radio station signal. When the radio station is identified as an analog station, the process may involve obtaining an audio snippet from the radio station, communicating the audio snippet to the fingerprinting service 110, and then updating data records 104F of the system 104 at step 210 with data received from the fingerprinting service 110 which is associated with the obtained audio snippet. Such data may include missing elements of music-related content, such as song title, artist name, album name, for example. At step 212, it may be determined that the audio snippet cannot be identified, and the system 104 can be updated accordingly at step 210.
At step 208, the process may identify the radio station associated with the broadcast radio signal as a digitally broadcast station. In this situation, the process may involve the apparatus 102 obtaining a digital signal decode from the digitally broadcast station. At step 214, the process determines whether the digital signal decode comprises at least one image or artwork. If the digital signal decode comprises at least one image or artwork (as determined at step 214), and if program services data associated with the broadcast signal are available (as determined at step 216), then the system 104 can be updated accordingly at step 210. Program services data as applied herein may include information such as music title, artist, album name, and other like data. If the digital signal decode comprises at least one image or artwork (as determined at step 214), and if program services data associated with the broadcast signal are not available (as determined at step 216), then the process may involve: obtaining an audio snippet from the radio station, communicating the audio snippet to the fingerprinting service 110, and updating data records 104F of the system 104 at step 210 with retrieved data associated with the obtained audio snippet.
At step 214, when the digital signal decode does not comprise at least one image, the process can determine at step 218 whether the digital signal decode includes at least one song title or at least one piece of artist-related data. When the digital signal decode does include at least one song title or at least one piece of artist-related data, then program services data associated with the digital signal decode can be communicated to an image retrieval service 112, and data records 104F of the system 104 can be updated at step 210 with data obtained from the image retrieval service 112. When the digital signal decode does not include at least one song title or at least one piece of artist-related data, then the process may involve: obtaining an audio snippet from the radio station, communicating the audio snippet to the fingerprinting service 110, and updating data records 104F of the system 104 at step 210 with data associated with the obtained audio snippet retrieved from the fingerprinting service 110.
At step 210, after appropriate updates to the data records 104F of the system 104 have been made, the process could in certain embodiments dwell on a current station or frequency and wait for content to change. In other embodiments, the process can seek the next broadcast signal or a different frequency, perhaps by using a different tuner 102A-102J of the apparatus 102.
Various embodiments of the present invention employ hardware, software, and other components for supplying advanced application services (“AAS”). A “service” can be considered content that is delivered to users via an IBOC broadcast signal which can include various types of data not classified as main program service (“MPS”) data or supplemental program service (“SPS”) data. Examples of AAS data include real-time traffic and weather information, navigation map updates or other images, electronic program guides, multicast programming, multimedia programming, other audio services, and other content. The content for AAS can be supplied by service providers which provide service data to an importer, for example. The service providers may be broadcasters located at studio sites, for example, or externally sourced third-party providers of services and content.
In the example shown, the radio system 608 may be a component of an “infotainment” system 610 installed within the vehicle 602 which can be programmed to provide both informational and entertainment based content, for example, such as music-related content. The system 610 may include computer-readable instructions such as middleware 612 programmed to employ application program interfaces (API's) and other software. For example, the middleware 612 may be programmed to decide where to source data (e.g., OTA or IP data) within the system 610, to decide what data or information to present to users of the system 610, and/or to execute other tasks.
In various embodiments, the system 610 may be configured to interact or collaborate with other components installed on the vehicle 602. For example, a telematics control unit 614 may communicate with the system 610, and the unit 614 may include a built-in modem and/or may possess “WiFi” or “Bluetooth” connectivity. A global positioning system (GPS) 616 may communicate information to the system 610, such as latitude or longitude information associated with the current position of the vehicle 602. In addition, various displays, touchscreens, or other types of user interfaces 618 may be provided to allow a user to access the functionality of the system 610.
