PDAs Phones Digital TV and Set-top Box Hyper Pen and Book PCs Ubiquitous e-Learning Devices
The Hard SCORM Authoring Tool • Automatic Generation of Hard SCORM Tags • Print Hardcopy Textbooks • Tags Are Recognized by Hyper Pens which is Connected to LMS
Design Issues • Authoring Hard SCORM Tags • The Metadata Wizard(New) • Searching on Repository • Pre-fetching of Learning Objects (New, for Pocket SCORM) • Automatic Sequencing Testing (Mew) • Video Presentation and Flash Playback • Video SCORM (New)
Presentation Recording • Select PowerPoint file • Adjust Camera • Select Style File • Start Recording • Authoring Metadata • Delivery
Presentation Editing and Processing • Add/Delete Slides • Combine Presentations • Adding Slides and Flash Objects
The Metadata Wizard • Metadata is useful for object reuse • Time consuming to fill in metadata • Background of Users • Need tools to help the user • A user profile is filled only once • Interactive questions may or may not be asked by the authoring tool • Deduction rules can be designed by professionals and customized to individual needs • The author makes a final confirmation of metadata
Learning Content Management System Authoring Tool Metadata Editor User Profile Question Agent Metadata Wizard Deduction Engine Deduction Rules Environment and Platform Information System Architecture of the Wizard
Implementation of the Wizard • Users make a final confirmation to use the generated metadata
Sequencing Testing • Sequencing Control Modes • Choice, Choice Exit, Flow, Forward Only • Problems • “Unreachable” Clusters • “Sink” Clusters • Solution • Automatic Sequencing Testing • Integrated with the Hard SCORM Authoring Tool
Activity Tree – with Problem Choice = true Choice Exit = true Flow = false Forward Only = false Choice = true Choice Exit = true Flow = false Forward Only = false Choice = true Choice Exit = true Flow = false Forward Only = false Choice = true Choice Exit = true Flow = false Forward Only = false Choice = true Choice Exit = true Flow = false Forward Only = false Unreachable Sink
Summary • Only works for the 4 Basic Control Modes • Extend for conditions and rollup rules (and others) • Automatic Testing • When to trigger the testing? • Convenience – User Friendly • How to fix the bug? • Proper suggestions by the system • Metrics of Sequencing and Navigation is an open issue

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 • 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 • Integrated with the Hard SCORM Authoring Tool Content Aggregation Web Tag Properties Video Tag
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 Scene Actor for video jump Web link
The Video SCORM Run-time • Integrated with the Hard SCORM LMS (Web-based) • Download video SCORM components from server Video Scene Web Content Video Control
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 • 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
Browsing Video SCORM on Simulator • Simulator: OSMOSYS SDK 2.1 • MHP 1.1
Video capture tool Audio capture tool Content Authoring & preparation Raw video & audio data Directories containing applications & assets MPEG-2 encoder MPEG-2 encoder Object carousel generator (broadcast file system) Multiplexer MPEG-2 Elementary stream Full transport stream (Incl. service information ) Transport stream playout system Modulator For satellite network only Upconverter Receiver (Set Top Box) General Broadcasting System
Status • PC-based • Video SCORM AuthoringTool • Video SCORM Run-time Environment • Integrated with the Hard SCORM LMS • Set-top Box and Broadcasting System • Simulator • Not yet completed
