style="text-indent:25px">激光電視的優(yōu)點(diǎn)：1、圖像清晰度可接近于發(fā)射端信源部分的清晰度。其原因之一是信噪比與連續(xù)處理的次數(shù)無(wú)關(guān)，由于雜波主要疊加在傳輸信號(hào)上，而采用二進(jìn)制的數(shù)碼信號(hào)，通過(guò)整形以及引入的檢錯(cuò)技術(shù)，很容易把這些雜波的影響消掉，模擬信號(hào)在傳輸過(guò)程中噪聲會(huì)逐步累積，而數(shù)字信號(hào)在傳輸中不會(huì)產(chǎn)生新的噪聲，即信噪比可基本保持不變，所以模擬信號(hào)要求信噪比S/N≥40dB，而數(shù)字信號(hào)*需≥20dB。原因之二是數(shù)字系統(tǒng)的非線性失真的影響很容易消掉，而模擬系統(tǒng)中的非線性失真會(huì)造成圖像畸變。激光電視的發(fā)展引起了相關(guān)人員的特別重視。嘉興高亮度峰米激光電視</p><p

style="text-indent:25px">場(chǎng)景激光電視的組成：（1）傳輸網(wǎng)絡(luò)。傳輸網(wǎng)絡(luò)處于前端設(shè)備和用戶(hù)分配網(wǎng)絡(luò)之間，其作用是將前端輸出的各種信號(hào)不失真地、穩(wěn)定地傳輸給用戶(hù)分配部分。傳輸媒介可以是射頻同軸電纜、光纜、微波或它們的組合，當(dāng)前使用較多的是光纜和同軸電纜混合（HFC）傳輸。（2）分配網(wǎng)絡(luò)。有線電視的分配網(wǎng)絡(luò)都是采用電纜傳輸，其作用是將放大器輸出信號(hào)按一定電平分配給樓棟單元和用戶(hù)。（3）用戶(hù)終端。用戶(hù)終端是接到千家萬(wàn)戶(hù)的用戶(hù)端口，用戶(hù)端口與電視機(jī)相連。用戶(hù)端口普遍采用單口用戶(hù)盒或雙口用戶(hù)盒，或串接一分支。未來(lái)用戶(hù)終端包括機(jī)頂盒、電纜調(diào)制解調(diào)器、解擾器等。嘉興高亮度峰米激光電視</p><p
