| Summary: | 碩士 === 國立交通大學 === 資訊工程學系 === 84 === With the advance of computer hardware and software
technology, theapplications of multimedia interactive
information systems become the risingtopics of computer business
and are very popular. Video is the popular media inmultimedia
systems and the applications of video are board in many aspects.
However, the volume of video data is very large, and it is
difficult todescribe the content of videos. It is necessary to
develop a database system toprocess, maintain and manage video
data for fast retrieval, reusing, on demandservice or other
applications. In this thesis we construct a prototype of an
interactive Chinese newsvideo database system. The system
provides users to easily retrieve the newsvideo clips by
graphical user interface. Each video clip in the system
containsa Chinese free text description which describes the
content of the video clip,and a list of attributes which
describe the features or other importantinformation of the video
clip. It supports the best matching query of thedescriptions and
exact matching query of the attributes. In our system, thereare
five major subsystems : annotation, indexing, text processing,
querymanipulation, and storage subsystems. Each video clip is
compressed in MPEG-IIstandard format, and is saved as a file.
This video database can be easilyapplied for the news video
applications, including news on demand service andelectronic
news.
