Searching for information of moving image contents, a search information transmitting apparatus transmitting or receiving search information represented as a tree structure operates in the following manner, in transmitting or receiving the search information. Upon receiving the search information as an input, a search information analyzing unit (101) analyzes the input search information, and outputs a plurality of search information elements constituting the search information. A filtering processing unit (102) extracts, based on a condition set by a condition setting unit (104), two or more search information elements among the plurality of search information elements supplied from the search information analyzing unit (101). A search information reorganizing unit (103) generates a partial tree of the search information represented by the tree structure, based on the two or more search information elements extracted by the filtering processing unit (102). The search information represented by the generated partial tree is then transmitted or stored.
