PROBLEM TO BE SOLVED: To sbdivid multimedia data, namely, redundant data of various characters regardless of a function and/or characteristics by means of a navigation graph. SOLUTION: A node (N'<SB>i</SB>) controls access to an associated data item (D'<SB>i</SB>) and at least one next node. A node and data relating thereto are grouped into a temporary cell (C'<SB>t</SB>) and the temporary cell has a start node and data relating to this node. Each of nodes grouped into the temporary cell follows a node that is already included in this temporary cell, until a size of the temporary cell reaches a threshold, a pair of mutually following nodes of the temporary cell for miniaturizing a parameter dependent on the number of data common for data relating to the pair of two nodes are identified. A determination cell is formed from data grouped into the temporary cell before the data relating to a pair of first nodes. COPYRIGHT: (C)2004,JPO&NCIPI |
