隨著無線科技的發展,無線網路的軟硬體已逐漸普及。人們可以利用手持式元件(如:PDA、SmartPhone),藉由此類設備的輔助,透過無線網路隨時地存取網際網路上的資源。以現有的網際網路資源來說,從文字與影像資訊(HTTP/HTML)到影音資料的傳輸(Movies/MP3),甚至是線上遊戲,這些都是引起消費者使用的動機。因此,在無線或行動網路上傳輸多媒體將是未來的發展趨勢。
本篇論文即針對多媒體在無線網路上的傳輸技術。以MPEG-4為主要的多媒體系統,利用其物件化的特性,針對無線環境上的兩大重點(高遺失率與低頻寬),設計一具有無線環境的調適機制,可適當地調整其內容,使已經壓縮編碼過的MPEG-4多媒體檔案可順利地在無線網路上傳輸。同時,我們實作整套系統,並將我們所設計的模組整合進MPEG-4系統的傳輸層(DMIF)中。
Due to the fast progress of wireless technology, the software and hardware for wireless network have gradually popularized. With these supplementary equipments, people using the hand-held devices (e.g., PDA, SmartPhone) access the resources on the Internet through the wireless networks. Among these popular resources on the Internet, the text information, images, movies, music and on-line games all motive the consumers to be interesting in accessing these services. Therefore, delivering the multimedia over the wireless/mobile networks will be the future trend in wireless technology.
Hence, in this thesis, we concentrate on the multimedia delivery scheme on the wireless networks. Exploiting the key feature of MPEG-4 system, object-based multimedia content, we design an adaptive mechanism, which can adjust the multimedia content based on the wireless environment, to solve the two problem in the wireless networks: low bandwidth and high packet loss. By this mechanism, the pre-compressed MPEG-4 multimedia can adequately be delivered over the wireless networks.
Furthermore, we also implement the MPEG-4 systems with integrating the designed module into the MPEG-4 delivery layer (DMIF).
