我國拓展數位地面廣播電視之政策研究

Abstract

隨著數位化科技的進步，使電視的發展得有機會向前邁進一大步，數位電視將可提供嶄新的數位多媒體資訊服務，成為未來家庭用戶重要的資訊傳輸寬頻媒介。在各種數位電視之傳輸網路中，地面廣播使用國家稀有頻譜資源，為推動國家公共利益之重要管道，其發展對國家經濟、社會、文化、教育等整體各方面均有深遠的影響，因此目前世界各國政府均積極重視數位地面廣播電視之推動。 本論文主要研究數位地面廣播電視之政策。首先對於其可提供之新服務與趨勢作探討，進而針對傳輸標準、頻道使用這兩大重要層面做分析比較。傳輸標準主要針對歐規與美規之標準，頻道使用則研究美國、英國、澳洲、韓國等已開播國家之管理規範，本論文並藉由問卷調查方式，瞭解我國廣電傳播學者對於相關政策制訂之意見。最後本論文對於我國拓展數位地面廣播電視之政策提出相關政策制定之建議。
