Abstract: Methods and apparatus to synthesize reference media signatures based on constituent media signatures generated by metered media devices are disclosed. An example apparatus includes a collector to collect first constituent media signatures from a first media device that identify a first portion of media, a collector to collect second constituent media signatures from a second media device that identify a second portion of the media, and a synthesizer to combine the first constituent media signatures from the first media device and the second constituent media signatures from the second media device to form a reference media signature that represents the media, the reference media signature for comparison with third constituent media signatures collected from a third media device to detect consumption of the media at the third media device.

Abstract: Example apparatus disclosed herein are to receive a log file, compare a first media monitor identification associated with an audio signature, a second media monitor identification associated with media metadata, and a third media monitor identification associated with event metadata. Disclosed example apparatus are also to determine if a first timestamp associated with the audio signature is within a time period, wherein the time period begins with a second timestamp associated with the media metadata and ends with a third timestamp associated with the event metadata. Disclosed example apparatus are also to validate that the audio signature satisfies a threshold for being stored as a reference signature based on at least one of the media metadata, the event metadata, the first timestamp, the second timestamp, or the third timestamp. Disclosed example apparatus are also to generate the reference signature including assigning the media metadata to the audio signature.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed to generate reference signatures from streaming media through the collection of metadata, generation of audio signatures, and association of the metadata with the generated audio signatures. The disclosure consists of a media monitor that collects metadata and generates audio signatures at a household and a central processing facility that generates reference signatures therefrom.
