1. A signal describing method for describing feature data characteristic of input data, comprising the steps of:

  • dividing said input data into a plurality of segments;

    calculating features of a respective segment, wherein a color feature is calculated by denoting a color histogram;

    measuring similarities between segments based on their calculated features;

    grouping said segments into scenes based on their calculated features and measured similarities;

    generating feature data corresponding to said scenes;

    transmitting said feature data with said input data,wherein said feature data is described using descriptors each having its attributes defined as lower-level elements;

    establishing a dissimilarity threshold by a user-defined setting or an automated setting; and

    establishing a temporal threshold as a maximum interval between two segments on a time base,wherein two segments that have a time gap that exceeds the temporal threshold are determined to be in different scenes.
