在此篇論文中,我們主要在三階網路環境架構底下,根據MPEG-21發展了一個多媒體串流工作階段換手機制。在三階的網路架構底下,應用代理伺服器在網際網路上不僅可以有效率地重復利用快取貯存區的資料而且更可有效地降低伺服器的工作量以及改善傳輸品質。而為了使得各式各樣的使用者裝置能夠在各種不同的網路環境底下擁有更加平滑、順暢的多媒體傳輸品質,因此採用可調性視訊編碼標準的分層多媒體串流技術。針對在三階網路架構能夠適應各種網路環境以及提供給各種類使用者裝置適當多媒體影音服務品質,則代理伺服器快取貯存管理策略的設計需要針對分層多媒體串流技術的特性而做改善,在此論文中快取儲存管理策略的設計考慮了頻寬管理機制以及多媒體影音的流行程度。此外,我們以“無所不在的串流”表示串流使用者允許在不同網路及不同使用者裝置之間作交換而不影響串流連線的連續性。為了能夠在三階網路環境底下達到無所不在的串流服務,代理伺服器的換手機制使得使用者影片播放品質更加平滑、順暢,並且可以減少使用者在工作階段換手之後的等待時間。
In this thesis, we develop an MPEG-21 based multimedia streaming session handoff mechanism over the 3-tier network environment platform. In the 3-tier Server-Proxy-Client network architecture, the proxy can provide cached and relayed functions to reduce server workload and distribute streaming traffic. In order to satisfy the characteristics of network heterogeneity and client devices' diversity, the proxy should provide different qualities of media streaming using scalable video coding. To achieve network-adaptive and device-adaptive for video streaming, layered proxy cache admission and replacement policies are designed with advances of scalable video coding for the 3-tier Server-Proxy-Client network architecture in this thesis. The proposed layered cache admission and replacement policies can manage the proxy cache in consideration of the quality-of-service and the video popularity. In this thesis, 'ubiquitous streaming' means that a streaming client is allowed to change the streaming session (i) from network A to network B, e.g., from ADSL to 3.5G or from 3.5G to WLAN, and even (ii) from A client device to B client device, e.g., from a desktop to a smart phone, on the run time, i.e., the streaming session keeps continuity when the attached network and the client device are changed. In order to achieve ubiquitous streaming over the 3-tier network architecture, a proxy handoff mechanism is designed to make video playback smoother and reduce the user's waiting time after the session handoff. In our experiments, we exhibit merits and performance results of the proposed cache admission and replacement mechanism. Additionally, we also analysis the experimental results of the proposed multimedia proxy handoff mechanism.
