現行的視訊串流系統在點對點架構和可調性視訊編碼的環境下,封包遺失影響甚鉅。比起主從式架構,點對點架構由於節點動態特性和網格拓樸上的多次轉傳,封包遺失率會比較高。比起沒分層的編碼,可調性視訊編碼由於框訊相依性高,掉了一個封包的影響會比較廣。本篇提出一個數學分析模型,分析封包遺失對影片品質的影響。
此外,封包保護方法可減少封包遺失對影片品質的影響,卻增加了頻寬的成本。因此,在頻寬有限的情況下,如何分配頻寬以保護可調性視訊編碼上不同層的資料讓影片品質最好是一個必須探討的問題。本篇在多種封包保護方法中選用與可調性視訊編碼最適合的網路編碼作為分析對象。
Under Peer-to-peer network and Scalable Video Coding, the impact of packet lost on current video streaming system is become worse. Compared with client-server network, Peer-to-peer network has more peer dynamic and multi-hop, therefore the packet lost has more high. Compared with non-layered coding, Scalable Video Coding has frame dependency, the impact of lost one packet is much wider. This paper develop an analytical model to analyze the impact of packet lost on video quality.
Furthermore, packet protection can reduce the impact of packet lost on video quality, but also add overhead of bandwidth. Therefore, in condition of limited bandwidth, how to distribute bandwidth to protect different layer of data to optimize video quality should be discuss. This paper select Network coding to analyze, which is suitable to Scalable Video Coding.
