Abstract
Example apparatus are to assign a first watermark to a first monitoring track and a second monitoring track, the first watermark detected in an audio stream of media. Example apparatus are also to, in response to at least a first threshold number of watermarks being assigned to the first monitoring track, group the first watermark with one or more other watermarks assigned to the first monitoring track to define a first media detection event. Example apparatus are also to, in response to at least a second threshold number of watermarks being assigned to the second monitoring track, group the first watermark with one or more other watermarks assigned to the second monitoring track to define a second media detection event. Example apparatus are further to cause transmission of the first media detection event and the second media detection event to a data collection facility.
