the video scorm project
The Video SCORM Project
  • How about SCORM on TV?
  • How about interactivity?
  • How about standard?
  • The DVB Multimedia Home Platform (MHP)
    • Defined by the DVB consortium
    • Adopted in many countries
      • Italy, Germany, Finland, Singapore, S. Korea, Australia and others
      • Included in the US OpenCable & ACAP standards
  • Can we combine MHP with SCORM?
what is mhp
What is MHP
  • A Platform Definition
  • A Set of Java APIs
  • A Set of HTML Document Type Definitions
  • An Extension to Existing Open Standards DVB, MPEG, JavaTV
  • MHP 1.0.x (1.0.0 – 1.0.3)
    • The original MHP specification plus updates
    • The most commonly deployed version of MHP
  • MHP 1.1.x
    • HTML Support, Stored Applications, Internet Client APIs, Smart Card APIs

The Video SCORM Authoring Tool
  • A video SCORM component is an SCO
  • Divides scenes into video stream files
  • Allow users to add metadata and sequence rules
  • However, sequence rules among scenes is our future work

interactive digital tv
Interactive Digital TV
  • Traditional Cable TV
  • Interactive TV (Video): interactivity between the users and broadcasting program, could be PC-based
  • Set-top Box and Digital TV
    • Limited computation power
    • Limited input device
  • Is MHP a solution?
running an mhp based program
Running an MHP-based Program
  • You must have:
    • Transport stream and object carousel generator
    • A playback system
    • Cable or satellite TV channel
  • Expensive? Yes
  • Alternative resource for research
    • Digital TV Simulator
