| 摘要(中) |
隨著網路越來越普及與頻寬不斷的成長，且科技日益進步，使用者對於網路的服務需求更是依賴並且更是趨於多樣性與多變性。隨著寬頻時代來臨，以及近年來VoIP與Video Conference技術的不斷進步。業界與學界對於Interactive Real-time Multimedia System環境的需求更是加重，促使市面上出現許多的相關產品。其中又以Video Conference與E-learning更是受到業界的重視。藉由Video Conference與E-learning系統，企業可完成企業內部的教育訓練與企業與企業間或企業與客戶間的遠距離視訊會議，以此可以減少許多的成本與時間。在另一方面，由於無線網路環境趨於發達，各種行動裝置的能力又不斷進步。因此對於思考利用行動裝置與無線網路環境來提供更完整的網路服務的可能性，更是近年來重要的課題。本論文就是以實作一個支援Video Conference功能之E-learning數位學習系統環境為目的，並且著重了無線網路環境與行動裝置技術進步之考量。因此，我們將整個客戶端的數位學習系統實作於PDA之上，以滿足未來市場上對於在無線網路環境之行動裝置上數位學習服務之需求。藉此以達到隨時、隨地、無遠弗屆之行動數位學習之環境。 |

As the Internet becomes more and more popularity, the network service becomes more multifarious and varied, Such as VoIP and the video conference technologies which advancement in recent years. The business and academic circle are interesting in Interactive Real-time Multimedia System environment. This makes market for this kind of product become important, especially the Video conference and E-learning system. To make use of these technique, business can accomplish the internal training、B2B and B2C video conference to reduce the cost and time. On the other hand, while the growth of wireless network and the ability of mobile device advancement. Now we are thinking out the possibility of using mobile device and wireless network to support a complete network service. The goal of this thesis is to implement a video conference support e-learning system, and we also think on the trend of wireless network and mobile device. So, all of the implement of the client side application are implement on a PDA device. On this way, we can construct an anytime anywhere e-learning environment. |
