  • 台灣無線電視(DTT)產業採用的DVB-T標準有了下一代的升級版,DVB-T2。DVB-T2可以提供更高的頻譜使用效率。但是升級需要耗費DTT業者的時間與轉換成本,同時觀眾也必須要換機上盒。台灣在2012年才進行完數位轉換,民眾可能有抗拒的心態再次換機上盒。此外,DVB-T2對業者帶來的效益仍是未知數。存在於許多不確定因素下,科技升級規劃對政府與電視廣播業者需要有通盤的考量。
    本研究探討兩種情況:一、DTT業者可以自由決定要不要升級,二、政府規定DTT業者一定要升級。如果業者可以自由決定,本研究嘗試藉由現有的資訊,包含業者財務狀況、頻道利用率、其他業者的選擇等等,找出既有業者與新業者是否會升級。而如果政府規定要升級,本研究將考慮業者的廣告收入、升級成本,以及時間價值,試圖找出最佳的升級時間點。
    研究結果顯示,當無線電視廣播業者可以自由選擇,由於財務情況以及製播能力有限導致高重播率,他們傾向停留在DVB-2。然而,如果業者在新的執照期間內被規定要升級至DVB-T2的話,透過研究的成本效益分析,馬上升級是最佳的策略。

    The new DTT standard, DVB-T2, has been widely adopted internationally. It enables higher spectrum efficiency, however, the migration to DVB-T2 takes time and money for television broadcasters, and viewers also have to buy new set top boxes for DVB-T2. The digital switchover had just be finished in 2012 in Taiwan, so the DTT viewers may be reluctant to buy new set top boxes. Moreover, the benefits brought by DVB-T2 is a question for DTT broadcasters. Since there are a lot of uncertainties of DVB-T2 migration, the transition issue requires a further investigation.
    In this research, there are two scenarios: DTT broadcasters are free to decide whether to migrate, and DTT broadcasters are forced by the government to migrate in a certain period. When broadcasters are free to choice, this study analyzes what kind of action would be adopted for incumbent broadcasters and new entrants with the current information like financial capability, channel utility, other broadcasters’ decisions. While the incumbent DTT broadcasters are forced to migrate to DVB-T2, the model considers revenue, cost, and time to figure out the right timing.
    The result concludes if broadcasters are free, they are not going to migrate to DVB-T2 since the current financial capability and the high rerun rates. However, if broadcasters are forced to migrate in a period of time, migrate instantly is the best strategy.
