DVB-T技術是一種數位電視傳輸的規格，它擁有單頻網(Single frequency network; SFN)、行動接收能力強且具回傳功能…等優秀特性，也是台灣在電視影像數位化上所選擇的規格，由歐洲廣播聯盟制定的此規格，也是目前世界上最多國家選用的規格，本論文將針對此一規格做詳細的介紹，包含通道編碼，調變方法等架構，盼望透過此研究，能提升我們對數位電視傳輸規格的認識，並在未來的研究上來提升其效率。 DVB-T is a digital video broadcasting specifications. It has some excellent advantages, like single frequency network, the strong ability of receiving signal and transmit signal. In Taiwan, also use the specification as the development in digital video broadcasting. The DVB-T technology was established by ETSI (European Telecommunications Standards Institute). Most countries choose DVB-T technology as their standard. In this paper, focus on the DVB-T specification, including the architecture, channel coding and modulation. We hope that we can improve our understanding of DVB-T through this research and help us to be deeper in this field in the future.
