METHODS AND APPARATUS TO MEASURE EXPOSURE TO BROADCAST SIGNALS HAVING EMBEDDED DATA
Example methods and apparatus to measure exposure to broadcast signals having embedded data are disclosed. An example broadcast signal exposure meter includes a first decoder to obtain an identifier of a broadcast station from an audio signal output by an end user broadcast receiver, a radio to tune to a broadcast signal from the broadcast station associated with the identifier of the broadcast station, a second decoder to obtain embedded data from the broadcast signal, the embedded data representing media contained in the broadcast signal, and an interface to provide the embedded data to a server, the server to determine audience measurement information for the media based on the provided embedded data.
The present disclosure relates generally to broadcast signals having embedded data and, more particularly, to methods and apparatus to measure exposure to broadcast signals having embedded data.
BACKGROUNDSome broadcast signals (e.g., frequency modulation (FM) radio broadcast signals) include, typically limited amounts of, embedded data. For FM radio broadcasts, an example communication protocol used to carry embedded data is radio data system (RDS), or radio broadcast data system (RBDS), which is the United States (U.S.) version of RDS. Example embedded information includes time, station identification, program information, etc.
Audience measurement entities (AMEs) perform, for example, audience measurement, audience categorization, measurement of advertisement impressions, measurement of media exposure, etc., and link such measurement information with demographic information. AMEs can determine audience engagement levels for media based on registered panel members. That is, an AME enrolls people who consent to being monitored into a panel. The AME then monitors those panel members to determine media (e.g., television programs or radio programs, movies, DVDs, advertisements (ads), streaming media, websites, etc.) exposed to those panel members. In this manner, the AME can determine exposure metrics for different media based on the collected media measurement data.
Some AMEs, such as The Nielsen Company (US), LLC (the Applicant of the present application) and/or other businesses, insert indiscernible (e.g., humanly inaudible, humanly imperceptible, etc.) watermarks into broadcast signals (e.g., an FM broadcast signal, a television signal, etc.). Example watermarks represent codes that identify broadcast stations, songs, times, etc. An example metering device, e.g., worn or carried by a panel member, records detected watermarks, and provides (e.g., uploads, transfers, sends, etc.) the recorded watermarks to a server associated with an AME. An example server decodes the recorded watermarks to measure exposure of the panelist to broadcasts, and determines audience exposure statistics. In contrast, the examples disclosed herein locally (e.g., at a portable metering device) measure exposure information (e.g., station, song, ad, time, etc.), and provide the locally measured exposure information to a server associated with an AME. The audience measurement examples disclosed herein utilize the embedded data already commonly provided in broadcast signals to measure exposure, and can be used to measure exposure to what was broadcast.
Reference will now be made in detail to non-limiting examples of this disclosure, examples of which are illustrated in the accompanying drawings. The examples are described below by referring to the drawings, wherein like reference numerals refer to like elements. When like reference numerals are shown, corresponding description(s) are not repeated and the interested reader is referred to the previously discussed figure(s) for a description of the like element(s).
The example broadcast signal 104 of
To receive audio signals, the example broadcast signal exposure meter 108 includes an example audio receiver 116 and an example microphone 118. The example audio receiver 116 and the example microphone 118 of
The example broadcast signal exposure meter 108 needs to be close enough to the FM radio 122 to receive the audio signal 120. The audio signal 120 may be received acoustically, wirelessly and/or electrically. For example, the broadcast signal exposure meter 108 and the FM radio 122 may be in the same moving vehicle 130 (e.g., a car, plane, train, boat, etc.), in the same room in a building, nearby outdoors, etc. Moreover, a panelist's broadcast signal exposure meter 108 can operate anywhere they are near a broadcast signal and a conventional receiver, such as, in a bar, store, etc. Further still, the broadcast signal exposure meter 108 could be electrically coupled to the FM radio 122 via, for example, an audio cable.
To decode the watermark code 114, the example broadcast signal exposure meter 108 of
As will be described in detail, the example broadcast signal exposure meter 108 of
To decode the embedded data 112 in the broadcast signal 102, the example broadcast signal exposure meter 108 of
In some examples, the embedded data 112 is stored in any number and/or type(s) of computer-readable storage devices 142, which may be non-removable, removable, volatile, and/or non-volatile for subsequent transfer (upload, transfer send, etc.) to, for example, the AME 136. Additionally, and/or alternatively, the embedded RDS data 112 may be provided to the AME 136 via, for example, a wireless transceiver 144 (e.g., a Wi-Fi transceiver, a satellite transceiver, a cellular transceiver, a near field communication (NFC) transceiver, a Bluetooth receiver, etc.) as the RDS data 112 is decoded, continually, at intervals, and/or when connectivity with the AME 136 is available. In some examples, the broadcast signal exposure meter 108 includes a wired interface 146 (e.g., a universal serial bus (USB) interface, a wired network interface, etc.) that enables the broadcast signal exposure meter 108 to transfer the embedded data 112 to another device for subsequently transfer to the AME 136.
Because the embedded data 112 contains information regarding specific pieces of media (e.g., songs, programs, shows, sports events, educational programs, advertisements, etc.) on the broadcast signal 104, the embedded data 140 can be readily used to form advanced media exposure associations. For example, 70% of listeners at 5 pm have dwelled for at least the next 30 minutes on a station that airs song X and song Y within 5 minutes of each other. Such information may be used to, for example, assist in song selection, target advertising, draw a target audience, etc.
In some examples, the example broadcast signal exposure meter 108 includes a location detector in the form of, for example, a global positioning satellite (GPS) receiver 148 to obtain location information. Additionally, and/or alternatively, the wireless transceiver 144 may be used to obtain location information. The location information may be stored in the storage 142 together with the embedded data 112, allowing exposure measurements to be associated with location. For example, 40% of listeners on I-94 at 8 AM on Mondays are tuned to All Sports 94.5, and another 40% are tuned to NPR.
