摘要

隨著無線傳輸技術的進步，在行動裝置上的多媒體的應用也愈來愈受到重視。以行動裝置本身在攜帶能力上的優勢搭配傳輸技術的成長，未來將會有更多行動影音的創新應用。然而，行動裝置不管運算速度、儲存空間等資源都非常的有限；無線傳輸也會因為訊號強弱變化而影響資料傳輸的穩定性。對於有即時需求網路影音串流，這些限制使得在實際開發應用與服務時，容易有一些在一般個人電腦開發時不易發生的問題出現。本篇文章將針對一些在設計開發行動影音串流平台與相關應用時容易碰到的問題做分析與討論。

As mobile networks technology develops, there are more and more attention paid to multimedia applications on mobile devices. There will be more and more innovative applications when the characteristic of the mobile device, mobility, can benefit from the advance of mobile networks. However, the resources of mobile device are very limited, including computation power and storage; the stability of transmission over mobile networks also varies with the signal strength. For the applications which have real-time requirement such as live mobile video streaming, there could be issues encountered which seldom happened when designed on a desktop computer. This article will focus on the issues we often encounter when designing and implementing mobile video streaming platform and related applications.
