Disclosed herein are methods and systems to help disambiguate channel identification in a scenario where fingerprint data of media content being rendered by a media presentation device matches multiple reference fingerprints corresponding respectively with multiple different channels. Upon detecting such a multi-match, a server or other entity will perform disambiguation based at least in part on a comparison of time of broadcast of the media content being rendered by the media presentation device with time of broadcast of the media content represented by the reference fingerprints. The server or other entity will thereby determine the channel on which the media content being rendered by the media presentation device is arriving, so as to facilitate taking channel-specific action.

A system, method, and computer-readable medium for providing recommendations based on a user interest. The method includes: generating at least one signature for at least one multimedia content element; querying, based on the generated at least one signature, a user profile to identify the user interest related to the at least one multimedia content element; generating at least one contextual insight based on the user interest, wherein each contextual insight indicates a user preference; searching for at least one content item that matches the at least one contextual insight; and causing a display of the at least one matching content item as a recommendation.

An example apparatus includes means for querying a first table to perform a first query of the first table using a hash corresponding to a first site signature, the first table including hash keys corresponding to respective reference signatures, the first query to obtain, from the first table, first qualifier data descriptive of a first reference signature corresponding to a first hash key; means for querying a second table to perform a second query of the second table, the second query to obtain a plurality of blocks of reference signatures; means for comparing a first block of site signatures with the plurality of blocks of reference signatures, the first block of site signatures to include the first site signature; and means for crediting media as corresponding to reference media represented by the first reference signature when the first block of site signatures matches the plurality of blocks of reference signatures.

Methods, apparatus, systems and articles of manufacture are disclosed to monitor a split screen media presentation. Example apparatus disclosed herein include an audio processor to process audio output from a media device to determine audio metering data to identify first media presented by the media device. Disclosed example apparatus also include a video signature generator to generate one or more video signatures associated with video output from the media device. Disclosed example apparatus further include a computer vision processor to identify a first region-of-interest of a split screen presentation of the media device including the first media in response to a determination that the one or more generated video signatures do not match reference video signatures corresponding to the first media.

System and methods are provided for managing use of media feeds in a media player. A media feed may be selected from a plurality of media feeds based on a feedback signal corresponding to an audio output signal of a media player, and a corresponding transmit signal may be configured for transmittal to the media player. The transmit signal may include a plurality of channels, and configuring the transmit signal may include selecting one channel from the plurality of channels based on the feedback signal, and conveying the media feed over the selected channel. The selected channel may be processed to carry the media feed, such as by frequency-modulating the media feed into the selected channel. The feedback signal may be processed, and control information may be determined based on the processing for controlling one or both of the selecting of the media feed and configuring of the transmit signal.

A computing system receives from a media presentation device a query fingerprint stream representing media content being presented by the media presentation device, where the query fingerprint stream has been determined to represent a first channel. The computing system then detects that a threshold mismatch exists between the received query fingerprint stream and a reference fingerprint stream representing the first channel, thus indicating a likelihood that the media presentation device has transitioned from presenting the first channel to presenting a second channel. Responsive to detecting the threshold mismatch, the system thus discontinues channel-specific action with respect to the first channel. For instance, the system could discontinue superimposing of first-channel-specific content on the presented media content and perhaps start superimposing of second-channel-specific content instead.

Apparatus, systems, articles of manufacture, and methods to identify and credit media using ratios of media characteristics are disclosed herein. An example apparatus to identify media includes a memory including computer readable instructions and a processor to execute the instructions to at least determine a first ratio based on a first time interval and a second time interval of a plurality of time intervals of a monitored media signature, determine a second ratio based on a third time interval and a fourth time interval of the plurality of time intervals of the monitored media signature, generate a monitored media ratio signature based on the first and second ratios, and compare the monitored media ratio signature with a reference ratio signature to identify the media.

An example apparatus to monitor media that is presented via a mobile device includes: an application monitor to determine when media presentation software is being executed by the mobile device; and a metering information collector to collect at least one of a signature or a code of the media presented by the media presentation software based on the media presentation software being executed by the mobile device.

A system and method for recognizing characters embedded in multimedia content are provided. The method includes extracting at least one image of at least one character from a received multimedia content item; identifying a natural language character corresponding to the at least one image of the at least one character, wherein the identification is performed by a deep content classification (DCC) system; and storing the identified natural language character in a data warehouse.
