摘要

現今流行的網路串流，Apple HTTP Live Streaming，其缺點無法隨著客戶端與伺服端的頻寬變化，提供相對應的位元率，導致使用者觀看品質不流暢。所以此篇論文是希望能解決以上遇到問題，能利用動態編碼和頻寬管理，達到即時影像可依據頻寬變化，而會改變輸出的影像品質，先以求達到流暢播放為目的，而後求保持最大頻寬使用量下，提供最高的播放品質。

The most popular Internet live streaming technique, Apple HTTP Live Stream, which causes that users suffer from the consistency in bitrate when the bandwidth between the user and the server varies. Thus, this article solves the issue mentioned previously. The method we conduct makes use of adaptive transcoding technique and bandwidth management approach in order to achieve the goad that the video stream quality varies in according to the bandwidth change. We have the stream fluency the major consideration while the maximum bandwidth utilization the minor to assure the highest video quality.
