Due to the advancement of network technology, video-on-demand (VoD) services are growing in popularity. However, individual\r\nstream allocation for client requests easily causes a VoD system overload; when its network and disk bandwidth cannot match\r\nclient growth. This study thus presents a fundamentally different approach by focusing solely on a class of applications identified\r\nas latency tolerant applications. Because video broadcasting does not provide interactive (i.e., VCR) functions, a client is able to\r\ntolerate playback latency froma video server. One efficient broadcasting method is periodic broadcasting,which divides a video into\r\nsmaller segments and broadcasts these segments periodically on multiple channels. However, numerous practical systems, such as\r\ndigital video broadcasting-handheld (DVB-H), do not allow clients to download video data frommultiple channels because clients\r\nusually only have one tuner. To resolve this problem in multiple-channel broadcasting, this study proposes a novel single-channel\r\nbroadcasting scheme, which leverages segment-broadcasting capability further for more efficient video delivery.The comparison\r\nresults show that, with the same settings of broadcasting bandwidth, the proposed scheme outperforms the alternative broadcasting\r\nscheme, the hopping insertion scheme, SingBroad, PAS, and the reverse-order scheduling scheme for the maximal waiting time.
