In a search information managing apparatus (1) managing search information (15) having a tree structure for searching for moving image contents, a search information analyzing unit (101) separates the search information into one or more structural search information elements (152) representing a structure of the moving image contents, one or more semantic search information elements (153) representing characteristics in semantic context of the moving image contents, and one or more signal search information elements (154) representing physical characteristics of signals of the moving image contents, and outputs the resulting elements. A unit search information forming unit (102-104) forms a small unit of search information (152A, 153A, 154A) by collecting at least one of the structural search information elements, semantic search information elements and signal search information elements output from the search information analyzing unit (101). By transmitting only the structural information of the moving image contents in advance and transmitting, as needed the unit search information corresponding to specific search information required by a searcher at the time of conducting a search, the amount of search information to be transmitted can be reduced.
