Video portal for a media space of structured video streams

The necessity for a video portal which supports an access to a specific video or its part from a huge video media space consisting of a large number of structured video streams is increasing. The video portal for a media space can be defined as a system which helps us to access videos through various kinds of media segments such as image, text, audio and video segments. In order to construct the video portal, we deal with structured video with metadata. Our system defines the structure of video in terms of document type definition (DTD), and describes the metadata of video with XML according to the DTD. We propose the video portal for structured video streams for the sports domain, and verify its usefulness based on a prototype system's performance.
