MPEG-7 Multimedia Data Description Scheme Design Tool Using MPEG-7 description scheme standards
Visualize description schemes
Easy to generate description scheme
Description language : XML DTD, XML Schema
MPEG-7 Multimedia Data Description Generator Consists of description editor and MPEG-7 description encoder Description Editor : User interface for editing video data
Scene detecting algorithms, image processing technique to extract values of
Color, Texture, Shape, Motion features, etc.
MPEG-7 description encoder : encoding video data and description data Meta-information in XML document

MPEG-7 Multimedia Data Retrieval Server Module Provides stable services interfacing meta information and video data
Provides search facilities, such as query module
support contents and text search module (e.g. Keyword + Color)
MPEG-7 Multimedia Data Presentation Module Viewing the video library data to users Consists MPEG-7 Player Module and Local search Module
MPEG-7 Player Module : decoding MPEG-7 video data for playing and
develop more useful function using MPEG-7 description information
providing captions and specific explanation
Local Search Module : interacts with MPEG-7 Multimedia Data Retrieval Server
