於寬頻家庭網路環境中使用多媒體內容分享服務時，進行中的網路資料傳輸與串流播放通常會因為使用裝置的移動或是網路位置的改變而導致服務中斷。本論文首先分析當使用者在進行多媒體內容分享服務時，有可能之移動情況，據以提出一套無縫式多媒體串流傳輸與播放機制，這機制將可以幫助已移動的家庭網路裝置快速重新建立連線、恢復影音串流傳輸並且維持多媒體播放不中斷。此機制之設計，無須修改實施裝置的系統底層與網路功能，可直接以軟體應用程式的方式來達成，可視為一低成本的解決方法。同時，本論文提出以OSGi 服務平台發展之實作雛型，並佐以實驗量測結果來說明該機制之功效。 In a broadband home network environment, users playing media content sharing services usually encounter severe problems of disconnection and media transfer/streaming service termination due to free movement of either a source or client device. This paper analyzes the user’s movement cases, and accordingly proposes a seamless media streaming and playing mechanism. This mechanism can provide fast re-connection establishment, resumption of media streaming, and playback continuity. In addition, this design is independent of the underlying OS and network kernel. Its development turns out to be an application-level software that can be installed in any OSGi-based home networked devices, so resulting in a lightweight solution. Further, this paper presents a proof of concept and reports experimental results to show the effort of the proposed mechanism.
