Introduction to XDVL

• Search among a huge collection of digital video
  files
• Include process from video creation to video
  delivery, plus other features
• Adopt a multi-tier model to increase usability,
  extensibility, and reliability
• Employ XML as an open standard framework in DVL
  data management

System Architecture

• Four primary components
• Video Server
• Indexing Server
• Query Server
• Client Applications
• Single DVL-Workstation or distributed system over
  the Internet

Video Server

• Storage subsystem
• Video capturing (video conversion)
• Video segmentation and storing
• Video streaming
• Export of meta-media attributes

8
Indexing Server

• Meta-data subsystem
• Extract and store video features
• Raw textual information
• Physical information
• Semantic information
• Text-based or content-based query

Query Server

• Information portal subsystem
• Accept queries from client application
• Send optimized queries to appropriate Indexing
  Servers
• Collect and rank results
• Varies information retrieval model

10
Client Application

• Presentation subsystem
• Query submission
• Query result presentation
• Video playback
