隨著電腦網路、硬體以及多媒體等相關技術迅速地發展，我們不再只是像以前一樣，從電視觀看影音娛樂，近日我們更可以透過網際網路抓取檔案，並在手持裝置上觀賞我們想看的多媒體內容。然而，單靠手持裝置有限的計算能力是無法提供高品質的影音娛樂，於是，手持裝置皆開始採用硬體解碼。
但是硬體解碼無法直接被現有的播放器使用，需要透過修改撥放器程式或是撰寫額外的套件來被使用，然而，不同的硬體解碼套件有許多相似的部分，開發者往往花費大量的時間做相同的事。因此將重覆的部分設計成一個標準流程，以加快開發的速度。
在本篇論文中，我們將焦點放在設計套件的擴展性和服務品質管理上。為了讓之後可以輕易的增加新的硬體解碼和服務品質感知的方法，我們將在本論文中提出一個解決方案，並說明所遇到的問題及解決方法。以實現一個高擴展性且有服務品質感知的解碼套件供之後的開發者使用。

| 摘要(英) |
As computer networks, hardware and multimedia technologies grow rapidly, we not only receive audio and video information from television as we used to do. Recently we can get multimedia file from Internet.
Moreover, we can playback these files on the mobile handheld device. However, the computing power of mobile handheld device is not enough to provide a high quality amusement of multimedia. Therefore, hardware decoder was introduced to solve this problem on the mobile handheld device.
But media player nowadays cannot use hardware decoder directly. It is necessary to modify player or develop plug-ins for hardware decoder. However, there are some similar parts with each other. So the developers usually spend much time at do the same things. Therefore, we design a standard process that deals with the similar parts for reducing the development time.
In this paper, we would like to focus on designing the expandable QoS plug-in. In order to add new hardware decoder and QoS rule easily, we point out the key problems that we encounter and propose a solution to solve them. Our main goal is to implement an expandable and QoS function decode plug-in for future developers.
