雖然無線電視肩負了免費收視和傳遞緊急訊息的責任,但根據國家傳播通訊傳播委員會的電視使用行為及滿意度調查報告指出,臺灣無線電視的使用率已降到14%左右,同時,有線電視和中華電信MOD的使用率分別來到了83%和12%左右。而且近年來也出現許多透過網路的數位媒體影音服務,皆壓縮到了數位電視的使用率。而且下世代的無線電視規格(DVB-T2)也在舉辦公聽會後,目前還未公佈相關無線電視升級計畫。臺灣無線電視未來發展仍存在許多不確定性。
同時美國聯邦通訊委員會(Federal Communications Commission, FCC)在2014年5月開會決定在2015年中把600MHz頻段的廣播電視頻譜搬移、釋出並拍賣做為行動網路的使用。
本研究採用網路程序分析(Analytic Network Process, ANP)的分析,在終止無線電視服務時,推測收視戶、廣播業者和政府所在意的因素,讓決策的考量得以更清晰。
網路程序分析的結果指出,收視戶和廣播業者最在意的是「收視戶」準則的面向,「替代基本頻道服務的方式」皆是兩方最看重的因素。政府方最在意的則是「政府」準則的面向,「頻譜效率」是他們最關注的因素。
而全部的專家的意見彙整後,則是認為「收視戶」的面向是執行此政策時最需要被關注的部分,「替代基本頻道服務的方式」是最重要的因素
Digital terrestrial television (DTT) takes the free-to-air service and delivering emergent message. However, according to National Communications Commission (NCC)’s TV behavior and satisfaction report that the DTT’s penetration is decreasing to 14% due to competition from the other multimedia content platforms and technologies. Cable television (CATV)’s penetration has reached about 83%. The penetration of mainstream internet protocol TV (IPTV) service provided by Chung-Hua telecom (CHT) has reached 12%. There are many kinds of new over the top (OTT) service in the couple years. And NCC has not planned the DTT’s upgrade plan after they held some public hearings. There are still many uncertainties for Taiwan’s DTT development.
On May, 2014, in America, Federal Communications Commission (FCC) planned to hold a 600MHz broadcasting spectrum license into auction for mobile use in mid-2015. This recalled us whether we should to allocate as much spectrum resource on DTT as before or not. This research adopted analytic network process (ANP) to find out what are the dimensions and factors that policy makers should care when terminating DTT service.
The results indicate that viewers and industrials care the viewers’ dimension the most when DTT service is terminated, and “ways to watch TV after terminating DTT” is the most important factor for both experts. Besides, the officials care the government’s dimension and the “spectrum efficiency” is the most important factor. As for overall experts’ opinion, the viewers’ dimension should be care the most, and the “ways to watch TV after terminating DTT” is the most important factor.
