Abstract: Methods and apparatus for over the top (OTT) media measurement are disclosed herein. Example methods include comparing, with an on-site meter in communication with an OTT service provider server, household data maintained by the OTT service provider server with anonymized panelist data provided by an audience measurement entity to identify a first person predicted to be included in a first household according to the anonymized panelist data but not included in the first household according to the household data, accessing media impressions collected by the OTT service provider server and corresponding to media accessed with a first OTT device associated with the first household, and crediting, with the on-site meter, usage of the first OTT device associated with access of the media to the first person based on the media impressions and demographic data obtained from the anonymized panelist data and attributed to the first person.

Abstract: Methods, apparatus, systems and articles of manufacture to monitor a media presentation are disclosed. An example method includes in response to receipt of a media identifier, extracting, by executing an instruction with a processor, a timestamp from the received media identifier. A time of receipt of the media identifier is determined. A difference between the time of receipt of the media identifier and the timestamp from the received media identifier is determined. A time shifted viewing code is calculated based on the difference The time shifted viewing code is transmitted to a media monitor that transmitted the media identifier, the time shifted viewing code to be reported when the media monitor reports monitoring information.
