當前我國數字電視廣播的實現方案，主要是通過各廣播電臺、電視臺的節目發射至通信衛星，再由地面接收站利用衛星數字電視解碼器（ ird ? integratedreceivedecoder ）接收衛星廣播信號，最後通過各地有線數字電視網將電視節目傳送到最終用戶。 -
A special address codeword produced by optical encoder at the side of transmission and data information are modulated on optical carrier and transferred. the data from different users are transmitted through optical fiber. the information belonging to local user is demodulated by the special optical decoder while optical signals carrying other users ’ information are filtered as noise
在發送端特定的光編碼器產生某一特定的地址碼，將數據信息與此地址碼調制在光載波之上發送出去，不同用戶的數據都在光纖媒質中傳輸，接收端用特定的光解碼器解出屬于自己的信息，而攜帶其他用戶信息的光信號，就像噪聲一樣被過濾掉。
