Hybrid measurement approach

This is a measurement approach that combines a census measurement with a panel measurement. Census measurement measures all accesses of the video streaming offerings of system participants. The precondition for this kind of measurement is the integration of the Nielsen measurement library into the measured players and content tagging on the basis of the valid AGF c-variable catalog (see C-variables). Thanks to the complementary measurement in the Desktop Panel, not only structural information of the panelists (e.g. demographic characteristics, device ownership), but also information about their video streaming usage are available. These data are matched with and calibrated to the census data.
