It provides a way to extend distance education to other mediums. Multimedia Home Platform (MHP) is a promising interactive digital TV standard. In order to extend the re-use of the resource database in SCORM, this thesis devises a new platform, which allows the use of SCORM resource to provide educational services on the MHP platform, i.e., T-Learning. Explicitly, I develop a SCORM compatible T-Learning system architecture named Resource-Reuseable T-Learning (RTL), which is capable of reusing the SCORM resource package. Moreover, to enhance the efficiency of parsing the T-Learning documents, I also propose a two-phase parsing algorithm called TPP. Our system architecture and the parsing algorithm make the DVB platform flexible, extensible, and easy to be integrated with the existing E-Learning SCORM materials. We demonstrate the prototype of RTL architecture in this thesis and show the efficiency of the TPP algorithm in our experimental results.1 Introduction 5 2 Preliminaries 11 2.1 MPEG-2 Transport Stream . . . . . . . . . . . . . . . . . . . . . . . . . . 11 2.2 DVB-MHP . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 13 2.3 SCORM . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14 2.4 Comparing E-Learning with T-Learning . . . . . . . . . . . . . . . . . . . 14 3 Resource-Reusable T-Learning Architecture 16 3.1 Design of T-Learning Server . . . . . . . . . . . . . . . . . . . . . . . . . . 16 3.1.1 SCORM Editor . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18 3.1.2 SCORM Handler . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18 3.2 Design of T-Learning Client . . . . . . . . . . . . . . . . . . . . . . . . . . 19 3.2.1 Interpreter . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 3.2.2 SCORM Parser . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 21 3.2.3 Program Generator . . . . . . . . . . . . . . . . . . . . . . . . . . 21 3.2.4 DOM tree Structure . . . . . . . . . . . . . . . . . . . . . . . . . . 22 3.2.5 Two-Phase Parsing Algorithm . . . . . . . . . . . . . . . . . . . . . 24 3.3 Import Issues in RTL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 28 4 Experimental Results 34 4.1 RTL Platform . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 34 4.2 Demonstration of RTL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36 4.3 Practicability of RTL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 38 4.4 Performance Analysis . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 39 4.5 Flexibility . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 43 5 Conclusion and Future Works 46 A Code of Transcoder 48 B Report : SCORM in Taiwan 50 B.1 Abstract . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 504487484 bytesapplication/pdfen-US數位遠距教學數位電視SCORMT-Learning,MHPthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/58419/1/ntu-95-R93944022-1.pdf
