The On-Device-Meter is a software provided by Nielsen for the panel-side recording of video usage on the respective end devices of the desktop and mobile panellists. The software is installed on the end devices of the panellists and is used to allocate the usage processes measured in the census with the Nielsen SDK to the panellist.

Online surveys are Internet-based surveys that are filled out online instead of on paper questionnaires. They are especially inexpensive and allow for quick data collection.

Out-of-home viewing refers to usage in the households of the AGF Panel that is generated by guests, meaning persons who do not live permanently in the household. Based on the model assumption that the panel represents all private TV households, a person uses TV either in his or her own household or in another household, so that usage as a guest is regarded as being representative of the usage of the panel member outside of his or her home. The usage of guests is transferred by fusion to panel members who have not watched TV in a blanket interval of 60 minutes before and after the guests’ use. Age and sex are the shared characteristics for the fusion. Other factors applied for the selection probability of a suitable panel member for the fusion are the frequency of out-of-home use according to information provided by the panel members themselves (from the Structural Survey), television usage in the last 28 days, and regionality. Out-of-home viewing has been incorporated into the daily AGF data since 07/01/2009.

Overlay ads are a sub-category of non-linear video ads. They are characterized by the fact that that are broadcast concurrently with video content, in a manner similar to banners. When users click on an overlay ad, they can be sent directly to the advertiser’s page, for example.

Overspill refers to the receivability and/or usage of a TV broadcaster beyond the actually intended broadcast area. This increases a broadcaster’s technical reach.

OWM is an acronym that stands for Organisation der Werbungtreibenden im Markenverband. (“Organization of Brand Advertisers”). It represents the interests of advertisers vis-à-vis the media.
