When a start key is operated, an inferring process of estimating a demand
of a user is executed on the basis of preset situation data, a user
profile, and situation data manually input via a situation setting key.
Based on the inference result, a genre list and a contents list are
reconstructed so that genres and contents items are arranged in order of
the degree of a demand of the user. The top three genres extracted from
the reconstructed genre list are associated with three selection keys,
and the names of the associated genres or labels of the genres are
displayed in genre name display parts. It enables the user to easily and
instantaneously select one of contents items to be processed.
