Sistema de indexación de vídeo por contenido y transmisión en tiempo real

Abstract

The interest in indexing and querying video data is growing rapidly. Desktop video is a new and attractive medium for communication between people using computers and networks. The main focus in any video information system is to develop a database management system with a friendly content-based retrieval of the digital video information. In this paper, we present an on-line video system for educational purposes. The interface consist of two main modules, An annotation-video-interface which can be used to put keywords, comments, proposal exercises, recommended lectures and so on in video segments. The annotations specify video sequences information for the automatic generation of a video library indexed by content. And a query-video-interface which can be used to extract the relevant segments of video that satisfy the specific query condition. We also describe the implementation of a real time video server, which make uses of a protocol designed for video conferencing to transmit the video sequences.
