Benefits of technology

Enables the reproduction and search of specific scenes by users, improving the management and retrieval of multimedia content by incorporating hierarchical structure information and characteristic metadata.

Problems solved by technology

Therefore, there remains a problem that it is impossible to also manage the structure of video data such as the hierarchical property of the video data.
Also, at the time of searching for a registered image, the title given to a corresponding index is used, causing a disadvantage in that in order to obtain an appropriate search result, an appropriate title needs to be input.

Abstract

Multimedia content containing moving pictures and audio is divided into multiple scenes and metadata is generated for each of the scenes obtained as a result of the division. 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 at least one descriptor describing semantic content, a structure, and characteristics of content.
