論文中文摘要:數位電視(Internet Protocol Television, IPTV)結合了網際網路、通訊以及多媒體來提供使用者服務,而隨著網際網路科技發展的快速,再加上頻道內容提供者的增加以及服務品質提升等優點,讓IPTV越來越受到大家的注意。IPTV是利用網際網路傳送數位訊號至用戶端,在用戶端會由機上盒(set-top-box)來進行預先接收頻道資訊的動作,由於頻寬的限制以及IPTV中的頻道數量極多,set-top-box無法像傳統電視(Cable TV)一樣同時接收全部的頻道資訊,因此當使用者在瀏覽頻道時,就可能會因為set-top-box來不及接收頻道資訊而造成延遲情況的發生並讓使用者對其降低收看欲望,也降低整體評價。本研究將介紹加入了使用者興趣這項因子來將頻道順序做重組,利用使用者的觀賞習慣與喜愛頻道類型,將其喜愛之頻道節目依類型再進行分類,聚集使用者在不同時段觀賞之頻道,減少選擇頻道時浪費過多時間於瀏覽之行為上,並提出Preload策略來降低延遲時間,模擬結果與傳統線性排序法相比,使用本研究提出之CIRI方法可縮短選台距離14%~47%,並同時降低延遲時間。
論文英文摘要:Internet Protocol Television (IPTV) has become one of the major Internet applications due to its variety of contents and services. However, hundreds of IPTV channels make users difficult to find their desired channels. Along with this problem, users often suffer from serious delay of the channel zapping time. Thus, reducing the channel zapping time is one of the major concerns of IPTV network deployment. In this thesis, we propose a method of channel interleaved reordering based on users’ interest (CIRI) to solve the problem of zapping time. By combining channel reordering and preload policy, the channel seek time of zapping time can be reduced significantly. Compared with the previous methods, the proposed scheme reduce the channel seek time by 14%~47% when up-down channel selection interfaces are used.
