摘要

近年來隨著可攜式裝置的普及，以及m-multimedia learning的發展日趨成熟，因此影響了人們的生活習慣。過去，在亞洲的學子學習時，往往一次都要攜帶好幾十本的書籍、幾百張的考試測驗卷，而且時常會因為科目眾多而混亂不已。為了解決此問題，本論文設計出有助於學習的使用情境且便於攜帶的e-multimedia learning系統。本服務提供學子們能夠使用可攜式裝置從網路獲取教學影片，或是透過數位機上盒將影片同步至可攜式裝置儲存，於是學子不需要再攜帶厚重的書籍，可以利用隨身攜帶輕便的可攜式裝置來達到無縫式學習的效果。其中更是應用了加解密技術來保證教學影片不會被輕易地竊取或是被不法業者利用，透過此技術可以提供學習資源提供者多一層的保護，讓我們的系統能夠保護這些智慧財產權。 結合加解密技術與m-learning的觀念，讓我們的系統創造了對學子或是教師們雙贏的局面。

In recent years with the popularity of mobile devices, as well as e-multimedia learning has matured, thus affecting habit of people. In the past, when the learners are studying in Asia, they are confusing of carrying dozens of books and hundreds of test paper because of numerous subjects. To solve the problem, this thesis designs the m-learning system that can provides students to use a portable device to get multimedia materials videos from the Internet, or use set-top-box to synchronize the multimedia materials videos to the portable device. Then students do not need to carry heavy books, and they can use lightweight portable device to achieve the effect of a seamless learning. To enhance media protection in m-learning system, we apply some algorithms to make our system to be DRM-enabled m-learning system, and it will solve the copy problem in the multimedia system. As the mentioned above, our system can provide some protections while media sharing, and the intellectual property rights. Combined with encryption technology and m-learning concept make our system a win-win situation between teachers and students.
