You can select songs that are close to human thinking and sensibility.
  • the selection priority music with the highest chain priority (the strongest connection) is used as the next song to be selected. Therefore, it is possible to realize continuous selection of music that is closer to human thinking and sensitivity.
  • selection candidates are extracted from a plurality of ID lists and a plurality of selection order lists, and You may comprise so that a music may be selected based on the priority of the chain
  • the number of selections, the quality of the selection order, and the relevance are applied as examples of parameters for determining the priority of the chain.

Abstract

Méthode et dispositif de sélection d’informations permettant d’effectuer facilement une sélection (sélection d’informations de programme telles une composition musicale) de façon naturelle et reflétant le mode de pensée et la sensibilité d’un être humain. La méthode de sélection d’informations de programme est employée pour sélectionner en continu un élément donné parmi des informations de programme. Les candidats à la sélection parmi les informations de programme sélectionnées après un élément prédéterminé des informations de programme sont extraits dans l’ordre de sélection des éléments sélectionnés auparavant parmi les informations de programme et l’un des candidats à la sélection extraits est déterminé en tant qu’élément d’informations de programme sélectionné après l’élément prédéterminé des informations de programme lorsque des éléments d’informations de programme sont sélectionnés en continu.
