From A for AGF Videoforschung to Z for zapping, the most important technical terms in video research are explained here.

TV-Total

TV-Total is provided in the system both as a summary of usage ("Fact," available in TV evaluations) and as a summary of providers in TV and convergence evaluations. TV-Gesamt as a Fact includes the usage of TV channels involved in the system. As a Fact, TV-Gesamt also includes channels that are measured but cannot be reported individually due to licensing agreements. In the audio matching measurement procedure, all channels involved in the system, as well as other channels defined by AGF, are measured. TV-Total as a Fact is the basis for calculating market share.

When reporting AGF data, the following labels, dimensions, and decimal places should be used. For further calculations, the decimal places available in the evaluation system should be used, regardless of the number of decimal places displayed.
