Presentation Outline 4 Project Aims 4 Introduction of Digital Video Library 4 Introduction of Our Work 4 Considerations and Approach 4 Design and Implementation 4 Future Plans

Project Aims 4 Learn different issues about DVL 8 existing such as Informedia(TM) done by CMU 4 Implement a small-scale model 8 Client interface for playback of media 8 Process data source/user queries in Chinese 8 Web Integration

Introduction of Digital Video Library 4 Functions of a DVL 4 Why Digital Video Library? 4 Issues about DVL 4 Techniques Addressing DVL Issues

Functions of a DVL 4 Storage and play back of video resources 4 Online access of video resources 4 Search of useful information through the vast data collections 4 Retrieval of the most relevant selections

Why Digital Video Library? 4 Digital data 8 easy to process in an automated way 8 takes advantage of the Internet 4 Multimedia content 8 more attractive 8 for education, training, sports and entertainment 4 Library management 8 An organized way of retrieval media contents

Issues about DVL 4 Building Video Databases 4 Indexing the Video Contents 4 Breaking the Video into Segments 4 Retrieving Video

Building Video Database 4 Extremely large space requirement 4 Choosing a video format 4 Online access of video resources

Indexing the Video Contents 4 Inaccessibility of information in video 4 Limitation of text-base descriptions 8 Tedious manual process 8 Cinematic information is complex to describe

Breaking the Video into Segments 4 Video paragraphing 4 Alternate representation of video 8 Text tile 8 Text abstract 8 Full-text transcript 8 Representative single image 8“Skim” video

Retrieving Video 4 Three principle for searching 8 Let user to skim the video object quickly with their interest 8 Adjust the size of video 8 Identify of desired video among multiple returned results 4 Ways to achieve 8 Small size of video returned 8 Information visualization

Overview of Digital Video Library System

Techniques Addressing DVL Issues 4 Speech Analysis 8 Speech recognition technology generates transcript 8 Pauses and silence in audio help paragraphing 4 Image Analysis 8 Detect significant changes in weighted color histogram 8 Interpret camera motion 4 Natural Language Processing 8 Query processing 8 Retrieval

Our Work 4 Focus and Target 4 Programming Environment 4 Design and Implementation 8 System Consideration 8 System Design 8 System Implementation 4 Future Plans

Focus and Target 4 Divide the project into modules that can be implemented in stages 8 digital video preparation 8 video playback 8 user query 8 web-integration

Programming Environment 4 Platform 4 Java as programming language 4 JMF API to present time-base media

Why use Java? 4 Platform independence 4 Network ready 4 International appeal 4 Easy to build GUI 4 JMF API for video playback 4 Disadvantages?

Presenting Time-Base Media with JMF 4 What is JMF? 8 Java Media Framework Application Programming Interface 8 Incorporating media data into Java 4 The high level architecture 8 Similar to traditional VCR 4 Data Source 8 Pull data-source and Push data-source 4 Media Presentation 8 Programmed or Interactive controls
