對於現今無所不在的網路環境中，人們可以透過行動網路及自身設備於任何時間、地點連取網路使用服務，所以近幾年下來行動設備及多媒體串流的應用十分流行。雖然有如此便利性，但有時會礙於環境及設備之關係，而有不便之問題。例如使用者於戶外，使用行動網路及自身行動設備觀看影像串流，若欲分享給周遭好友們觀看時，可以礙於螢幕尺寸的限制，而當是亦無合適的設備，所以使得觀看不方便，甚至無法多人同時觀看。
本論文針對這樣的情境，設計出多媒體內容分享方法（multimedia content sharing method），使用者可透過分享的方式，讓被分享者透過自身的行動設備也可以獲得和自身一樣的影像串流。本文將此服務建立於IP多媒體子系統（IP Multimedia Subsystem, IMS）網路之上，希望使用者可以透過不同的接取網路都能夠應用此服務，本研究透過IMS相關之Open Source來開發本系統機制，及設計出相應的多媒體串流來源，以便搭建於IMS網路之上。

The services of the network environment which is omnipresent currently and accessible to users via the mobile Internet and personal devices anytime and anywhere will popularize applications of mobile devices together with multimedia streaming in the foreseeable future. Despite convenience, the mobile Internet is not available to a user sometimes because of the network environment and associated devices. For example, video screaming subject to the screen size or equipment inappropriate is not always shared to more friends conveniently by a device user outdoors through the mobile Internet and the personal devices.
In this thesis, we designed a multimedia content sharing method by which a user’s own video screaming can be shared to other people via their mobile devices.The shared service constructed on the network of IP Multimedia Subsystem (IMS) is accessible to users via different access networks. Moreover, we depend on IMS-based open sources to develop a mechanism for the system, designing more sources with respect to multimedia streaming on the IMS network.
