摘要

行動裝置的快速發展,讓使用者對於此時此地、人與人之間即時的多媒體影音傳輸需求與日俱增。使用者需求的增加,促進了行動網路技術的發展與行動網路應用的興起。其中,行動網路應用又以行動影音為主要應用趨勢。行動影音的相關技術主要有RTP與HTTP多媒體串流技術。HTTP逐漸成為行動影音發展的主流技術。HTTP多媒體串流技術,可以分為Progressive download及Dynamic adaptive。Progressive download不考慮多媒體內容在傳輸時,頻寬的變化,但是能提供用戶品質一致的多媒體內容。Dynamic adaptive考慮多媒體內容在傳輸時,頻寬的變化,可以依據頻寬大小決定下載的多媒體內容品質。有鑑於此,本論文提出行動串流傳輸策略(Mobile Streaming Transfer Strategy),透過整合Progressive download和Dynamic adaptive機制,我們可以最大限度地減少多媒體內容傳輸延遲,並滿足用戶期望體驗(QoE),有效地支援異質無線網路下的行動影音傳輸。
ABSTRACT

The rapid development of mobile devices increases the demand for here and now, person to person multimedia transfer services. The increasing demand for multimedia transfer services then stimulates the development of mobile network technologies and applications. Regarding mobile network applications, the mobile video has become the most popular application. Mobile video technologies include RTP and HTTP multimedia streaming technologies. HTTP has been adopted as the main technology for the deployment of the mobile video. The HTTP multimedia streaming technology can be divided into two mechanisms: progressive download and dynamic adaptive. The progressive download mechanism does not consider the bandwidth change during the transfer of multimedia contents. The progressive download mechanism can support transfer of multimedia contents with consistent quality. On the other hand, the dynamic adaptive mechanism considers the bandwidth change during the transfer of multimedia contents. Based on the bandwidth change, the dynamic adaptive mechanism then determines the quality of the content to be accessed. By integrating progressive download and dynamic adaptive mechanisms, we then can minimize content transfer delay and satisfy the desired user Quality of Experience (QoE). Therefore, by integrating progressive download and dynamic adaptive mechanisms, this paper proposes a mobile streaming transfer strategy to effectively support mobile video in the heterogeneous wireless network environment.
