Automated data-matching includes obtaining first and second stored fingerprints generated from first and second data. The stored fingerprints are divided into frames, and grouped into first blocks and second blocks including an equal number of frames. Each frame included in a current first block is compared to each frame included in a current second block to determine a number of matching frames, and a hamming distance between the current first block and the current second block is determined, based at least in part on the number of matching frames. A determination is made, based at least in part on the hamming distance, whether the current first block and the current second block match.

Disclosed are a method for recognizing an image by an electronic device and a configuration of the electronic device for same. The method for recognizing an image by an electronic device of the present disclosure comprises the steps of: capturing an image of content; acquiring, form a server, content recognition information matching a recognized text by recognizing the text from a text area, if the text area is identified in the captured image, and acquiring, from the server, content recognition information matching an extracted fingerprint by extracting the fingerprint from the captured image, if the text area is not identified in the captured image; and storing at least one of the content recognition information matching the acquired text and the content recognition information matching the fingerprint.

Disclosed herein is a music service that enables consumers listen to a broadcast radio station without commercials. The service operates by shifting the source channel of a radio from the broadcast radio to a streaming audio service for the duration of the commercial. In some embodiments, the service utilizes any of: a radio including native firmware/software, a mobile device such as a smart phone executing an application, cooperative integration of a radio and a mobile device, or master/slave relationship between a mobile device and a radio. The mobile device listens to the radio broadcast and determines when to shift between the radio broadcast and the streaming audio via any of audio fingerprint analysis, radio station behavioral analysis, radio station metadata, and/or radio station voice recognition analysis.

Methods, apparatus, systems and articles of manufacture are disclosed selectively generating and storing hashed reference signatures. An example method disclosed herein determining whether watermark coverage of a first media segment satisfies a dropout constraint, the first media segment corresponding to a first monitoring time interval of a media source feed and, when the watermark coverage of the first media segment does not satisfy the dropout constraint hashing first media signatures associated with the first media segment to generate corresponding first hashed signatures and generating first reference data for the first media segment, the first reference data including the first hashed signatures and the first media signatures. The example method further includes, when the watermark coverage of the first media segment satisfies the dropout constraint, generating second reference data for the first media segment, the second reference data including the first media signatures.

Methods, apparatus, and machine-readable storage media to monitor media presentations are disclosed. A disclosed example apparatus includes a locator to compare a location of a mobile device with a set of reference locations at which audio monitoring is to be performed. The disclosed example apparatus further includes an audio receiver to enable a microphone of the mobile device to collect audio for media monitoring when (1) the location of the mobile device corresponds to a first one of the reference locations and (2) a media presentation monitor at the first one of the reference locations indicates a likelihood of media being presented at the first location satisfies a threshold. In some disclosed examples, the audio receiver of the example apparatus is to disable the microphone from collecting audio for media monitoring when the location of the mobile device does not correspond to any of the reference locations.

In accordance with some implementations, a method for measuring viewership of media content is disclosed. The method is performed on a client system. The client system obtains identification information for individuals who have agreed to participate in a media viewership totals measurement study, detects a first user of the client system, determines media content being presented in proximity to the first user, automatically determines if the first user is an individual who has agreed to participate in the media viewership totals measurement study; and generates viewership data according to the determination.

A person can use a portable electronic device to electronically purchase or otherwise request a product, service or other deliverable related to audio programming to which the person is listening at the time they initiate the request. The request is fulfilled by a service that analyzes the audio content to identify the deliverable the person desires.
