<p>In order to search for information on dynamic image contents, a search information transmitting apparatus for transmitting or receiving search information expressed by a tree structure operates as follows when it transmits or receives search information. In response to the input of search information, a search information analyzing unit (101) analyzes the search information inputted and outputs a plurality of search information elements constituting the search information. Under the condition set by a condition setting unit (104), a filtering unit (102) extracts two or more search information elements from the search information elements given from the search information analyzing unit (101). On the basis of the two or more search information elements extracted by the filtering unit (102), a search information reconstructing unit (103) creates a subtree of the search information expressed by a tree structure. The search information indicated by the created subtree is then transmitted or stored.</p> |
