<P>PROBLEM TO BE SOLVED: To obtain a hint information description method capable of reducing processing cost (throughput, memory usage, etc.) resulting from analysis and reproduction of metadata. <P>SOLUTION: Multimedia content containing moving pictures and audio is divided into multiple scenes, and metadata is generated for each of the divided scenes. It is possible to generate metadata containing scene structure information metadata that describes the hierarchical structure of the content in addition to scene section information and titles. Also, a name or an identifier of each descriptor contained in the metadata is described as hint information for manipulation of metadata composed of one or a plurality of descriptors describing semantic content, a structure, and characteristics of content. <P>COPYRIGHT: (C)2008,JPO&INPIT |
