    Abstract: PROBLEM TO BE SOLVED: To express a large number of attribute values with bits constituting vector descriptors for multi-medial data and rearrange them, and then, to hierarchically express and store the vector descriptors corresponding to the number of the attribute values and to retrieve the multi-media data using the stored representation data. SOLUTION: In the multi-media data retrieval system and method large number of the attribute values described by vector descriptor are quantized and the quantized attribute values are expressed in a bit format, the attribute values expressed in the bit format are rearranged in the order from the highest position bit to the lowest position bit, and the vector descriptors are hierarchically expressed. The number of the rearranged attribute values and the attribute values being entered are encoded as variable length codes, and stored only the variable length attribute value among the stored attributes corresponding to the number of the attribute values are reversely encoded in variable length to be rearranged reversely and the original attribute values are restored. The restored attribute values are reversely quantized and the reversed quantized attribute values are compared with the attribute value already stored in a multi-media database, and the multi-media data are searched.
