Continuous evaluation of the excerpts is preceded by questionnaires aimed at identifying the viewing tendencies of the spectators and their declared preferences for certain types of program.

This preliminary phase can also be used to study the context of television viewing in the given time frame depending on the quantity of equipment, the presence of children, the means used to choose the programs, meal times, and so on. These behavioural questions permit the generation of many targets, which are used to evaluate the level of appreciation of the program excerpts.

Medianalyst can handle about fifty targets, each comprising at least 15 people, for example, with or without children at home, single or multiple television sets, whether television is watched at mealtime, etc. The results are not to be interpreted as a quantitative measurement, but as the average opinion of a group of people.

As in the case of a traditional program test, the explanation for the variations in appreciation observed in real time is given by the focus groups.
