Definitions
- the technology described in this patent document relates to systems and methods for providing supplemental data (e.g., metadata) that is associated with over- the-air radio broadcast signals.
- supplemental data e.g., metadata
- Over-the-air radio broadcast signals are used to deliver a variety of programming content (e.g., audio, etc.) to radio receiver systems.
- Such over-the-air radio broadcast signals can include conventional AM (amplitude modulation) and FM (frequency modulation) analog broadcast signals, digital radio broadcast signals, hybrid analog and digital broadcast signals, or other broadcast signals.
- Hybrid radio broadcasting technology and digital radio broadcasting technology can deliver audio and data services to mobile, portable, and fixed receivers.
- Service data that includes multimedia programming can be included with radio broadcasts.
- the broadcast of the service data may be contracted by companies to include multimedia content associated with primary or main radio program content.
- service data may not always be available with the radio broadcast. In this case it may be desirable to identify the audio content being broadcast, and match service data with the audio content.
- Some current broadcast radio content information systems rely on digital "fingerprinting" of the audio content.
- the audio fingerprinting process can consume a lot of memory of the radio receiver and the identification service for the fingerprinting can be expensive in terms of cost and in terms of resources such as memory resources and processing resources of the radio receivers.
- an example radio system includes an intermediate communication platform that provides an interface to an Internet network, and a first server including: a port operatively coupled to the intermediate communication platform, processing circuitry, and a service application for execution by the processing circuitry.
- the service application is configured to: receive geographic location information of a radio receiver via the intermediate communication platform, determine one or more radio broadcasts available to the radio receiver according to the geographic location information, and send metadata for the radio broadcast to the radio receiver via the intermediate communication platform, the metadata including an indication whether content of the radio broadcast is suitable for an audio fingerprinting process.
- An example radio receiver includes radio frequency (RF) receiver circuitry, an Internet network interface, a display, processing circuitry, and a client application program that includes instructions for execution by the processing circuitry.
- the RF circuitry is configured to receive a radio broadcast signal.
- the client application program is configured to send geographical location information to an audio metadata service application via the Internet network interface, and receive via the Internet network interface, metadata for a radio broadcast available to the radio receiver, the metadata including an indication whether content of the radio broadcast is suitable for an audio fingerprinting process.
- FIG. 1 is a block diagram illustrating an overview of embodiments of the radio system.
- FIG. 2 is a block diagram of an example of a server to provide an Internet Protocol stream to radio receivers.
- FIG. 3 is a flow diagram of an example of a method of distributing metadata to radio receivers.
- FIG. 4 is a block diagram of portions of an exampl e of a radio receiver.
- Over-th e-air radio broadcast signals are commonly used to deliver a variety of programming content (e.g., audio, etc.) to radio receiver systems.
- Main program service (MPS) data and supplemental program service (SPS) data can be provided to radio broadcast receiver systems.
- Metadata associated with the programming content can be delivered in the MPS data or SPS data via the over-the- air radio broadcast signals.
- the metadata can be included in a sub-carrier of the main radio signal.
- the radio broadcast can be a hybrid radio signal that may include a streamed analog broadcast and a digital audio broadcast.
- Sub-carriers of the main channel broadcast can include digital information such as text or numeric information, and the metadata can be included in the digital information of the sub- carriers.
- a hybrid over-the-air radio broadcast can include an analog audio broadcast, a digital audio broadcast, and other text and numeric digital information such as metadata streamed with the over-the-air broadcast.
- the programming content may be broadcast according to the DAB standard, the digital radio management (DRM) standard, radio data system (RDS) protocol, the radio broadcast data system (RBDS) protocol, or a high definition (HD) IBOC radio protocol.
- DAB digital radio management
- RDS radio data system
- RBDS radio broadcast data system
- HD high definition
- the metadata can include both“static” metadata and“dynamic” metadata. Static metadata changes infrequently or does not change.
- the static metadata may include the radio station’s call sign, name, logo (e.g., higher or lower logo resolutions), slogan, station format, station genre, language, web page uniform resource locator (URL), URL for social media (e.g., Facebook, Twitter), phone number, short message service (SMS) number, SMS short code, program
- PI identification
- Dynamic metadata changes relatively frequently.
- the dynamic metadata may include a song name, artist name, album name, album image, artist image (e.g., related to content currently being played on the broadcast), advertisements, enhanced advertisements (e.g., title, tag line, image, phone number, SMS number, URL, search terms), program schedules (image, timeframe, title, artist name, DJ name, phone number, URL), service following data, or other information.
- the radio receiver system may receive both static metadata and dynamic metadata.
- Another approach to provide service data is to combine radio information broadcast over-the-air (OTA) with Internet Protocol (IP) delivered content to provide an enhanced user experience.
- OTA radio information broadcast over-the-air
- IP Internet Protocol
- An example of this type of service is DTS ® Connected Radio IM service, which combines OTA analog/digital AM/FM radio with IP delivered content.
- the combined service receives dynamic metadata (such as artist information and song title, on-air radio program information and station contact information) directly from local radio broadcasters, which is then paired with IP-delivered content (e.g., metadata), and displayed in vehicles.
- IP-delivered content e.g., metadata
- the DTS Connected Radio service supports all global broadcast standards including analog, DAB, DAB+ and HD RadioTM.
- the radio receivers of the vehicles integrate data from Internet services with broadcast audio to create a rich media experience.
- One of the Internet services provided is information about what the radio stations are currently playing and have played.
- service data may not always be available with a radio broadcast, and it may be desirable to send an audio fingerprint to identify the content of the over-the-air radio broadcast and receive metadata for the identified radio broadcast for presentation to the user.
- the audio fingerprint could be transmitted from the in-vehicle radio receiver to a server that performs automatic content recognition (ACR) to identify content of the over-the-air radio broadcast.
- ACR automatic content recognition
- the digital fingerprinting and identification of the audio fingerprint can be expensive in terms of cost of the service and in terms of resources of the radio receiver, such as processor and memory use. These resources may be wasted if the broadcast audio being received by the radio receiver is not suitable for the ACR fingerprinting and identification process. For example, if the broadcast audio does not include music, the ACR process may fail. This may happen if the broadcast audio contains content of a talk program or a commercial. An improvement would be to verify that the broadcast audio is suitable for ACR fingerprinting and identification before the process is started.
- FIG. 1 is a block diagram illustrating an overview of embodiments of the radio system.
- a traditional broadcast radio station 100 transmits an OTA audio signal 105 to the radio receiver 110 of a vehicle.
- the OTA audio signal 105 can be an analog audio signal, a digital audio signal, or a hybrid audio signal.
- the radio service provided is a combined OTA-IP radio service, and the in-vehicle radio receiver 110 can receive both an OTA audio signal 105 and an IP stream.
- the IP stream is received via an intermediate communication platform 108 from one or more servers 120.
- the intermediate communication platform 108 may be a cellular phone network or a telematics network.
- FIG. 2 is a block diagram of an example of a radio system server to provide an IP stream to radio receivers.
- the server 220 includes a processing circuitry 272, a memory 274, and a service application 276 or application program interface (API) for execution by the processor 272.
- the service application 276 can comprise software that operates using the operating system software of the server 220.
- the server 220 includes a port 270 operatively coupled to an interface to the intermediate communication platform 208 that provides the IP stream and receives information from radio receivers.
- the in- vehicle radio receiver 110 sends geographic location information to the service application of a server 120.
- One or more of the servers determines the radio broadcasts available to the radio receiver according to the geographic location information, and the service application sends the metadata for the determined radio broadcasts to the radio receiver via the intermediate communication platform.
- the one or more servers also sends an indication of suitability of the content of radio broadcasts for the fingerprinting process.
- the indication can be included with the metadata (e.g., in a specified field of the metadata).
- the indication is that the content is either suitable or not suitable for audio fingerprinting.
- An indication of suitability is sent for each radio broadcast of those radio broadcasts determined to be available to the radio receiver.
- the indications of suitability can be a flag or a digital code word stored in memory for radio broadcasts.
- the indications of suitability of fingerprinting can be stored in association with the metadata for the radio broadcasts.
- the service application determines audio metadata of a radio broadcast corresponding to the audio fingerprint and sends the determined audio metadata 125 to the radio receiver 110.
- the service application may track the radio broadcasts being tuned to by multiple radio receivers.
- the service application may send the audio metadata to multiple radio receivers receiving the radio broadcast.
- the audio metadata may be sent using the intermediate communication platform 108.
- the radio receiver 110 may do nothing or may merely send an audio fingerprint.
- the radio receiver 110 may display the metadata (e g., static metadata) that is available.
- the resources of the radio receiver are not wasted by generating and sending a digital fingerprint that would fail the ACR fingerprint identification process.
- the server 120 includes a memory that may store a fingerprint database that stores the audio metadata in association with audio fingerprint information in the server memory.
- the service application determines the audio metadata by retrieving the audio metadata from the memory using the audio fingerprint.
- the service application receives the audio metadata from an audio identification source 150.
- the service application of a first server 120 receives the audio fingerprint 130 from the radio receiver 110 and forwards the audio fingerprint 140 to the audio identification source 150.
- the first server and the audio identification source may communicate using a communication network.
- the communication network may be the intermediate communication platform 108 or another communication network.
- the server 220 can include a second port 260 operatively coupled to an Internet network interface 215.
- the Internet network interface 215 includes an Internet access point (e.g., a modem), and the port 260 can include (among other options) a communication (COMM) port, or a universal serial bus (USB) port.
- COMM communication
- USB universal serial bus
- the audio identification source 150 is shown as residing in the cloud in FIG. 1.
- the term“cloud” is used herein to refer to a hardware abstraction. Instead of one dedicated server processing the audio fingerprint and returning the audio metadata, sending the audio fingerprint to the cloud can include sending the audio fingerprint to a data center or processing center.
- the actual server used to process the audio file content information is interchangeable at the data center or processing center.
- the audio identification source 150 may include a second server that includes the fingerprint data base.
- the audio identification source 150 receives the audio fingerprint 140 forwarded from the first server and returns the audio metadata 160 to the first server and may send other associated metadata to the first server 120.
- the first server 120 sends the audio metadata 125 on to the radio receiver 110.
- FIG. 3 is a flow diagram of an example of a method 300 of providing metadata to a radio receiver.
- the method relates to a vehicle that is in contact with a radio system that combines an OTA radio broadcast with IP delivered content, such a DTS Connected Radio system for example.
- the method may be performed using a client program of the radio receiver of the vehicle.
- the in-vehicle radio receiver tunes to a radio station, and the radio receiver lacks dynamic metadata associated with a program currently being broadcast by the radio station.
- the radio receiver has queried the radio service system for static radio station metadata for the radio broadcast.
- the radio service system may include an application program interface (API) or service application executing on a server of the radio service system.
- API application program interface
- the radio receiver may send geographic location information with the query to the radio system, and the API sends static metadata for any radio broadcast that is available for reception by the radio receiver.
- the API also includes in the metadata an indication for a radio broadcast whether the content of the radio broadcast is suitable for audio fingerprinting and identification.
- the radio receiver has received an indication from the API for the radio broadcast missing the dynamic metadata that the radio broadcast is suitable for ACR fingerprinting and identification. Because of the indication, at 320 the radio receiver generates an audio fingerprint and sends the audio fingerprint to the API.
- the ACR fingerprinting process may be performed by the client program or by other software of the radio receiver.
- the radio receiver sends the audio fingerprint to the radio system using an Internet connection.
- the radio system identifies the audio program corresponding to the audio fingerprint and determines the audio metadata associated with the audio program.
- the API distributes the dynamic metadata to the radio receiver and may di stribute the dynamic metadata to other radio receivers that are receiving the radio broadcast (e.g., via the intermediate communication platform).
- the dynamic metadata is distributed to the radio receivers that are capable of receiving the radio broadcast regardless of the radio station to which the receivers are tuned.
- the radio receiver may store an audio fingerprint database, and before sending the audio fingerprint to the radio system, at 330 the radio receiver may first determine if it is storing the missing the dynamic metadata locally. For example, the radio receiver may store the results of previous audio fingerprinting and may check the database to see if the corresponding audio program was previously identified. If the audio fingerprint is found in the local database, the radio receiver uses the corresponding dynamic metadata for the radio broadcast. This reduces the resources consumed at the radio receiver in determining the audio metadata.
- the radio receiver receives an indication from the API that the content of the radio broadcast is not suitable for ACR fingerprinting.
- the client program of the radio receiver at 345 does not expend any resources of the radio receiver such as processing bandwidth, memory space, or communication time in generating and sending a digital fingerprint of the radio broadcast.
- the radio receiver may display the metadata (e.g., static metadata) that is available.
- FIG. 4 is a block diagram of portions of an example of a radio receiver 400.
- the radio receiver is able to receive an OTA radio broadcast and is able to receive IP delivered content.
- the radio receiver is a DTS Connected Radio receiver.
- the radio receiver 400 may be the radio receiver 110 of a vehicle shown in the example of FIG. 1.
- the radio receiver 400 includes a wireless Internet network interface 440 for receiving metadata via wireless IP and other components for receiving over-the-air radio broadcast signals.
- the Internet network interface 440 and receiver controller 430 may be collectively referred to as a wireless internet protocol hardware communication module of the radio receiver.
- the radio receiver 400 includes radio frequency (RF) receiver circuitry including tuner 456 that has an input 452 connected to an antenna 454.
- the antenna 454, tuner 456, and baseband processor 451 may be collectively referred to as an over- the-air radio broadcast hardware communication module of the radio receiver.
- the RF circuitry is configured to receive an audio broadcast signal .
- an intermediate frequency signal 457 from the tuner 456 is provided to an analog-to-digital converter and digital down converter 458 to produce a baseband signal at output 460 comprising a series of complex signal samples.
- the signal samples are complex in that each sample comprises a“real” component and an“imaginary” component.
- demodulator 462 demodulates the analog modulated portion of the baseband signal to produce an analog audio signal on line 464.
- the digitally modulated portion of the sampled baseband signal is filtered by isolation filter 466, which has a pass-band frequency response comprising the collective set of sub carriers fi-f n present in the received OFDM signal.
- First adjacent canceller (FAC) 468 suppresses the effects of a first-adjacent interferer.
- Complex signal 469 is routed to the input of acquisition module 470, which acquires or recovers OFDM symbol timing off set/ error and carrier frequency offset/error from the received OFDM symbols as represented in received complex signal 469.
- Acquisition module 470 develops a symbol timing offset At and carrier frequency offset Af, as well as status and control information.
- the signal is then demodulated (block 472) to demodulate the digitally modulated portion of the baseband signal.
- the digital signal is de-interleaved by a de-interleaver 474, and decoded by a Viterbi decoder 476.
- a service de-multiplexer 478 separates main and supplemental program signals from data signals.
- the supplemental program signals may include a digital audio file received in an IBOC DAB radio broadcast signal .
- An audio processor 480 processes received signals to produce an audio signal on line 482 and MPSD/SPSD 481. In embodiments, analog and main digital audio signals are blended as shown in block 484, or the supplemental program signal is passed through, to produce an audio output on line 486.
- a data processor 488 processes received data signals and produces data output signals on lines 490, 492, and 494.
- the data lines 490, 492, and 494 may be multiplexed together onto a suitable bus such as an I 2 C, SPI, UART, or USB.
- the data signals can include, for example, data representing the metadata to be rendered at the radio receiver.
- the Internet network interface 440 may be managed by the receiver controller 430. As illustrated in FIG. 4, the Internet network interface 440 and the receiver controller 430 are operatively coupled via a line 442, and data transmitted between the Internet network interface 440 and the receiver controller 430 is sent over this line 442.
- a selector 420 may connect to receiver controller 430 via line 436 to select specific data received from the Internet network interface 440.
- the data may include metadata (e.g., text, images, video, etc.), and may be rendered at substantially the same time that primary or supplemental programming content received over-the- air in the IBOC DAB radio signal is rendered.
- the receiver controller 430 receives and processes the data signals.
- the receiver controller 430 may include a microcontroller that is operatively coupled to the user interface 432 and memory 434.
- the microcontroller may be an 8-bit RISC microprocessor, an advanced RISC machine 32-bit microprocessor, or any other suitable microprocessor or microcontroller. Additionally, a portion or all of the functions of the receiver controller 430 could be performed in a baseband processor (e.g., the audio processor 480 and/or data processor 488).
- the user interface 432 may include an input/output (I/O) processor that controls the display 444, which may be any suitable visual display such as an LCD or LED display.
- I/O input/output
- the user interface 432 may also control user input components via a touch-screen display. In certain embodiments, the user interface 432 may also control user input from a keyboard, dials, knobs or other suitable inputs.
- the memory 434 may include any suitable data storage medium such as RAM, Flash ROM (e.g., an SD memory card), and/or a hard disk drive.
- the radio receiver 400 may also include a global positioning system (GPS) receiver 496 to receive GPS coordinates.

- the radio receiver may include a GPS receiver 496 and the client may send GPS coordinates as the geographical location information.
- the client 446 receives metadata for any radio broadcast that is available to the radio receiver at its indicated geographic location. Included in this metadata is an indication for each radio broadcast whether the content of the radio broadcast is suitable for the ACR fingerprinting and identification process.
- the client when audio metadata is missing or unavailable for the current radio broadcast to which the radio receiver is tuned, the client generates an audio fingerprint of the radio broadcast when the indication for that radio broadcast is that its content is suitable for the audio fingerprinting process.
- the client 446 sends the generated audio fingerprint to the audio metadata service application via the Internet network interface.
- the audio fingerprint is processed by the service application, and the client 446 receives dynamic metadata associated with the radio broadcast corresponding to the audio fingerprint.
- the dynamic metadata may be received via the Internet network.
- the dynamic metadata is received via one or more sub-carriers of the main channel OTA broadcast.
- the client 446 displays the information included in the received dynamic metadata.
- the client 446 does not generate the audio fingerprint.
- the client 446 may do nothing in response to the missing audio metadata or may display the metadata that is available (e.g., static metadata instead of dynamic metadata).
- the systems, devices, and methods described provide metadata to a radio receiver of a vehicle.
- the radio receiver is able to perform audio fingerprinting, but the systems, devices, and methods prevent the radio receiver from performing the audio fingerprinting and requesting identification for the audio fingerprint when the content of a radio broadcast is not suitable for the fingerprinting and identification process. This saves significant computing resources and communication bandwidth of the radio receiver.
