在多媒體串流服務中，媒體播放的順暢度一直都是個重要指標，而其中最重要的關鍵，就是讓緩衝器維持足夠的封包量。如果當緩衝器不幸發生下溢時，將導致影片發生播放中斷的情況; 而當緩衝器發不幸生溢位時，則造成有傳輸次數過多的問題。
可適性媒體播放技術(Adaptive media playout) 是一般通用的作法又可稱之為AMP，它是透過調整播放速率來抑制緩衝器發生下溢或溢位的問題。然而，過分的調整播放速率將可能大大影響影片的平滑度以及影片的畫質。
本文中提出一種有效的作法，當處於無線網格網路中進行影片串流服務時，將可以有效降低播放中斷的問題。當與AMP 類型的方法相較之下，所提出的方法有額外考量到在無線網路中節點的傳輸品質，以及影片發送端傳輸速率的調整。我們的作法是採用ETT 指標。因為ETT 指標比最小跳躍數指標多考慮了鏈結品質以及鏈結頻寬，因此，我們利用它去建立一條介於影片發送端和其指定的接收端之間的影像串流傳輸路徑。如果在傳輸過程中其影片發生播放中斷的情形，則發送端根據當下緩衝器的封包量決定啟動調控及預測的機制來設定串流的傳送速率。
透過模擬的結果顯示，我們提出的方法相較於一般AMP 的方法更能夠有效地降低播放延遲以及避免造成有額外的播放延遲時間。此外，在無線網格網路中，緩衝區的封包量也能夠有效的維持在相對穩定的狀態。

Maintaining sufficient buffer is crucial for multimedia streaming services. Buffer overflow causes redundant transmissions and buffer underflow causes play out interruptions.
Therefore, solutions must be devised in order to avoid the above problems.
Adaptive media playout (AMP), which changes the playout rate according to the occurring possibility of buffer underflow or overflow, is a popular approach for video streaming services. However, over-adjustments of playout rate can greatly affect the smoothness of the video and also the video quality.
This paper proposes an effective approach to reduce playout interruptions for video streaming services in wireless mesh networks. In contrast to AMP-type methods, the proposed approach considers the transmission quality of nodes in wireless networks and adjusts feeders’ transmission rate. Our method uses ETT metric to establish the streaming path between a video feeder and its designated receiver. To better utilize the relatively limited bandwidth in wireless networks, a video feeder changes the streaming speed according to the estimation on the occurring time of buffer underflow/overflow during video playout.
Through simulation results, the proposed algorithm is shown to be able to reduce delays more efficiently than the general AMP approach. Also, the buffer size is better maintained in wireless mesh networks.
