| dc.description.abstract | 為能提供近乎隨選視訊的服務，以多個頻道來廣播一個熱門影片可以縮短觀眾所需等待的時間。以一個120分鐘的影片為例，使用傳統的廣播方式，以4個頻道反覆的播放這個影片，則觀眾所需等待的時間可以縮短到30分鐘以內。假如用戶端的接收機能將多個頻道中播放的影片資料暫存起來。以相同的頻寬，快速廣播的方式比傳統的廣播方式更能縮短觀眾所需等待的時間。等待時間平均為4分鐘，即使最長等待時間也只需8分鐘。但是快速廣播在實作上也有很多問題，如影片必須切割成多個區段，多個廣播頻道的同步問題，用戶端接收各個影片區段時可能發生的延遲問題。本篇論文旨在以快速廣播法實作在區域網路提供熱門視訊服務的服務端，與其中實作所發生的問題。 | zh_TW |
| dc.description.abstract | Using multiplae channels to broadcast a hot video can reduce the viewer’’s waiting time to approach video-on-demand service. For a 120-minutes movie, conventional broadcasting schemes can support the movie every 30 minutes with 4 video channels. Suppose the set-top box at client end can buffer porions of the playing video on disk. For a given bandwidth, fast broadcasting schemes can provide users with shorter waiting time as compared with conventional broadcasting schemes. The average waiting time is 4 minutes even the longest waiting time is 8minutes. However fast broadcast has many problems in implementing, such as the movie must be divided into many segments, the synchronous problem of multiple video channels and the delay problem of receiving each segment in the client. In this paper, we present a hot video-on-demand server based on fast broadcast schemes and solve the problems in implementing the system. | en_US |
