Project Aims  Learn different issues about DVL  Implement a small-scale model  Client interface for playback of media  Process data source/user queries in Chinese  Web Integration

Introduction of Digital Video Library  Functions of a DVL  Why Digital Video Library?  Issues about DVL  Techniques Addressing DVL Issues

Functions of a DVL  Storage and play back of video resources  Online access of video resources  Search of useful information through the vast data collections  Retrieval of the most relevant selections

Why Digital Video Library?  Digital data  easy to process in an automated way  takes advantage of the Internet  Multimedia content  more attractive  for education, training, sports and entertainment  Library management  An organized way of retrieval media contents

Issues about DVL  Building Video Databases  Indexing the Video Contents  Breaking the Video into Segments  Retrieving Video

Techniques Addressing DVL Issues  Text description of Video  Speech Analysis  Image Analysis  Natural Language Processing

Our Work  Focus and Target  Programming Environment  Design and Implementation  System Overview  System Consideration  System Design  System Implementation  Future Plans

Focus and Target  Divide the project into modules that can be implemented in stages  digital video preparation  video playback  user query  web-integration
