Advanced Generalized Conservative Staircase Method for Broadcasting Popular Movies

碩士論文(全文於2009/07/01公開)[[abstract]]在使用者等待時間、儲存空間需求以及磁碟I/O讀取率這三方面，generalized conservative staircase broadcasting method 比 conservative staircase broadcasting method 有較佳的效率。但是這個廣播機制可能會造成使用者端觀看影片時，產生播放中斷。因此，在本論文中，我們首先去探討這個問題與它如何造成使用者觀賞時的播放中斷，接著我們提出Advanced generalized conservative staircase broadcasting method 並且確保它的連續播放。最後我們分析所提出的廣播機制與generalized conservative staircase broadcasting method有相同的效能。[[abstract]]The generalized conservative staircase broadcasting method has a better performance in terms of the combination of the subscriber’s access latency, buffer requirement and disk I/O transfer rate as compared with the conservative staircase broadcasting method. However, it may cause a film to become discontinuous at a subscriber’s site. In this work, we first point out the defect and explain how it causes the film to become discontinuous. Then we present an advanced generalized conservative staircase broadcasting method to ensure continuity. Finally, we analyze that the proposed method keeps the same performance as the conservative staircase broadcasting method
