Dttb ( digital television terrestrial broadcasting ) is one of the present digital television broadcasting modes, whose transmission media is earth. after a decade of intense research and development, the standards of digital television satellite broadcasting and digital television cable broadcasting have been confirmed. but the standard of digital television terrestrial broadcasting is still in disputation, for its transmission environment is rather awful, its spectrum resource is very limited and its service required is disperse, so it is potential to be improved in many aspects
數字電視廣播發展近十年來，衛星和有線電纜廣播的基本傳輸體制已確定，而地面廣播由於傳輸環境惡劣，頻譜資源有限，應用需求分散，其標準在各國仍有極大的爭議，因為目前沒有一套標準能解決實際地面傳輸中的所有問題，因此數字電視地面廣播在許多方面都有很大的改進潛力。 -
