Abstract: Methods and apparatus to associate audience members with over-the-top device media impressions. An example audience measurement apparatus includes a reporting message receiver to receive a first reporting message from a client device coupled to a residential gateway having an internet protocol (IP) address. An AME ID determiner is to assign an audience measurement entity (AME) identifier to the IP address provided by the received first reporting message. A redirect instructor is to send a redirect instruction to the client device to cause the client device to send a second reporting message to a database proprietor, the redirect instruction to include the AME identifier and the IP address. A DP message reporting receiver is to receive, in response to the sent redirect instruction, a third reporting message from the database proprietor that includes a database proprietor (DP) identifier.

Abstract: Methods and apparatus to associate audience members with over-the-top device media impressions. An example audience measurement apparatus includes an impression monitoring system to monitor and log media impressions based on impression requests received via network communications from over the top devices. A linkage database system is to implement the impression monitoring system. A processor in circuit with the impression monitoring system is to: generate Internet protocol (IP) address-to-cookie mappings; associate household identifiers of households with ones of the IP address-to-cookie mappings; and associate ones of the household identifiers to the logged media impressions based on IP addresses associated with the media impressions and based on the household identifiers associated with the ones of the IP address-to-cookie mappings.

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.

Abstract: Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to credit commercial broadcasts are disclosed. Example commercial crediting apparatus disclosed herein compare first identification information and first timing information obtained from a first monitored data feed with second identification information and second timing information in a second monitored data feed to identify a first final distributor code represented in the second monitoring data feed, the first identification information and the first timing information corresponding to a first commercial represented in the first monitored data feed. Disclosed example apparatus also access data that maps a first original distributor code to the first final distributor code, identify the first commercial in lineup data based on the first original distributor code, and adjust, based on a duration of the first commercial, a duration obtained for a first media program listed in the lineup data.

Abstract: Methods and apparatus to facilitate matching of names for same media content are disclosed. Example methods include analyzing first data associated with first media content and, when a program name/identifier and/or episode name/identifier is not identified in the first data, supplementing the data with second data to form third data and processing the third data with respect to fourth data associated with second media content and calculating a composite match score including a program match score and an episode match score based on processing the third data with respect to the fourth data. When the first media content is determined to match the second media content based on the processing of the third data with respect to the fourth data and a comparison of the composite match score to a threshold is satisfied, a normalized media name is generated for the first media content and the second media content.

Abstract: Methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to credit commercial broadcasts are disclosed. Example commercial crediting apparatus disclosed herein compare first identification information and first timing information obtained from a first monitored data feed with second identification information and second timing information in a second monitored data feed to identify a first final distributor code represented in the second monitoring data feed, the first identification information and the first timing information corresponding to a first commercial represented in the first monitored data feed. Disclosed example apparatus also access data that maps a first original distributor code to the first final distributor code, identify the first commercial in lineup data based on the first original distributor code, and adjust, based on a duration of the first commercial, a duration obtained for a first media program listed in the lineup data.

Abstract: An example includes a segment collector to: access impression records indicative of media access segments, the media access segments including start times and end times corresponding to media accessed by a panelist; and determine ones of the impression records that include a watermark corresponding to a first media platform presenting the media; a segment classifier to convert a first one of the impression records including the watermark to a converted impression record; and combine the converted impression record corresponding to the first media platform and a second impression record corresponding to a second media platform; and a media creditor to generate audience measurement metrics based on the combined impression records.
