    Abstract: Methods, apparatus, systems and articles of manufacture to credit media segments shared among multiple media assets are disclosed. Example methods disclosed herein include comparing a sequence of monitored media signatures with a library of reference signatures to determine a signature match, the monitored media signatures representative of a monitored media presentation. Disclosed example methods also include determining a duration and an offset of the signature match, the offset to represent a position of the signature match relative to a start of a reference media asset associated with the signature match. Disclosed example methods further include crediting a segment of the monitored media presentation represented by the signature match to an identifier of a class of media assets including the reference media asset in response to a determination that (i) the duration of the signature match does not exceed a first threshold and (ii) the offset does not exceed a second threshold.

    Abstract: Methods and apparatus to identify alternate language versions of media based on signature matching are disclosed. Example apparatus disclosed herein include a signature matcher to compare signatures in monitored data with reference signatures to determine signature match strengths associated with portions of the monitored data, the reference signatures associated with reference media assets. Disclosed example apparatus also include a data segmenter to divide the monitored data into first and second segments, the first segments including temporally adjacent portions of the monitored data having signature match strengths that satisfy a threshold, the second segments including temporally adjacent portions of the monitored data having signature match strengths that do not satisfy the threshold. Disclosed example apparatus further includes a trend determiner to determine, based on a pattern of the first and second segments, whether the monitored data is associated with an alternative language version of one of the reference media assets.

    Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to determine virtual WiFi data rate. An example disclosed herein includes a control frame receiver to capture control frames from a user device. The example disclosed herein further includes a bitrate calculator to calculate a bitrate for each control frame by dividing a bitmap of a control frame by an amount of time between the control frame and a previously captured control frame. The example disclosed herein further includes an interval timer to control a length of time that the control frames are captured before calculating the virtual bandwidth. The example disclosed herein further includes a virtual bandwidth calculator to calculate the virtual bandwidth after the length of time, the virtual bandwidth calculated by dividing an average bitrate from the control frames by the length of time.

    Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to encrypt media for identification. An example apparatus includes a mesh generation controller to generate a mesh based on an encryption matrix; an overlap controller to eliminate overlapping ones of edge connections of the mesh; an edge labelling controller to generate random labels for the edge connections based on a number of remaining ones of the edge connections of the mesh; an encrypted value controller to generate encrypted values based on the random labels; and an encryption controller to encrypt an input matrix with the encrypted values to enable identification of the input matrix.

    Abstract: Example apparatus disclosed herein to implement signature matching with meter data aggregation for use in media identification applications include a match job aggregator to aggregate batches of meter data from a meter to form aggregated meter data associated with the meter, and a hash matcher to identify a valid hash key match between meter hash keys generated from meter signatures in the aggregated meter data and reference hash keys corresponding to a collection of media assets. Disclosed example apparatus also include a signature matcher to align, based on the valid hash key match, a sequence of reference signatures corresponding to a first media asset associated with the valid hash key match and a corresponding sequence of the meter signatures, and compare the sequence of reference signatures and the corresponding sequence of meter signatures to identify media represented by at least a portion of the sequence of the meter signatures.
