摘要

在過去十幾年裡，為了讓網路串流能更順暢地傳輸，已有許多學者提出一些相關的串流排程架構，諸如Fast scheme, Staircase scheme, Harmonic scheme 等方法；他們都是串流排程演進過程中重要的產物，並不斷地被改進。除此之外還有許多種方法被提出，在此我們以一種稱之為 ”Crescent”的串流排程作為後進請求資料補送的機制，結合一傳統的頻道重複廣播方法” Staggered(channels) broadcasting”，能有效縮短接收端接收串流的等待時間，並降低其資料緩衝空間的需求，讓資料接收端能更順利的接收與播放影音資訊。

In order to discover a more efficient broadcasting scheme, we’ve searched through many reviews of relevant research before creating our proposed scheme. Since there have been so many multi-functional schemes proposed by researchers, among them the Fast, Staircase, Harmonic Schemes et al., and having viewed their relative strengths and weaknesses, we finally chose a scheme called “Crescent ” as a basis for creating a new and more efficient broadcasting scheme, then by combining it with one of the traditional broadcasting methods, the Staggered Broadcasting Scheme. We formulate herein a new hybrid scheme, the Crescent Staggered Broadcasting Scheme that reduces clients’ waiting time, allowing clients to receive a data stream more efficiently than other schemes through utilization of our proposed scheme.
