Abstract
A browsing method and apparatus using metadata are disclosed. In the browsing method, multimedia content and metadata about the multimedia content are stored. The multimedia content is classified based on corresponding metadata of the multimedia content. Virtual folders containing the classified content are created. The content is browsed using the virtual folders. In a method of creating virtual folders, a root-node containing a plurality of multimedia content items is created. The root-node is divided into a number of nodes to create first-generation sub-nodes, and each of the first-generation sub-nodes is divided into a number of nodes to create n-th-generation sub-nodes. Nodes having no sub-nodes are created as virtual folders while searching the created nodes ranging from the first-generation sub-nodes to the n-th-generation sub-nodes in a certain sequence. Exemplary embodiments of the present invention can efficiently browse and easily access desired content when there is a large number of content items.
