style="text-indent:25px">激光電視的重要部件待突破激光器是激光顯示系統(tǒng)中很為昂貴以及重要的部件。多采用半導(dǎo)體材料，如何降低成本將是激光電視產(chǎn)業(yè)化亟待解決的問題。另一方面，由于受制于體積及技術(shù)影響，國產(chǎn)半導(dǎo)體光源技術(shù)還有待進一步提升。產(chǎn)業(yè)化競爭激烈液晶電視和LED電視當(dāng)?shù)?，激光電視價格依然偏高。并且激光電視產(chǎn)業(yè)化規(guī)模仍無法與液晶或LED抗衡，其規(guī)?；档统杀具€有一定的難度。超薄化仍是挑戰(zhàn)由于激光電視采用透射式，雖然屏幕很薄，但激光發(fā)射器仍有一定的厚度（大概25cm厚，而且所配的屏幕尺寸越大，厚度就越大），無法做到與LED液晶電視一樣超薄化。</p><p style="text-indent:25px">場景激光電視的基礎(chǔ)知識：常用有線電視器材。1、電纜：型號:常用電纜；75-5；75-7；75-9；75-12；發(fā)泡:單護發(fā)泡、雙護發(fā)泡；類型:發(fā)泡電纜、耦芯電纜、進口電纜；特點:頻率越高，損耗越多。2、放大器(高電平放大器、中電平放大器、低電平放大器)；A:高電平放大器用于天線放大器，用戶放大器，增益大在40dB以上，信噪比較差，輸入低60dB；特點:低輸入，高輸出；B:中電平放大器用在支干線上，增益在25-30dB，如KA5134，信噪比較好。C:低電平放大器用在主干線上，增益在18-25dB，信噪比較好。激光電視的發(fā)展引起了相關(guān)人員的特別重視。</p><div

style="text-indent:25px">激光電視的編碼壓縮方法：差值脈沖編碼調(diào)制。標(biāo)準(zhǔn)數(shù)字電視采用的是主類和主級。概括地說，圖像壓縮的原理是利用了圖像中的兩種特性：空間相關(guān)性和時間相關(guān)性。一幀圖像內(nèi)的任何一個場景都是由若干像素點構(gòu)成的，因此一個像素通常與它周圍的某些像素在亮度和色度上存在一定的關(guān)系，這種關(guān)系叫做空間相關(guān)性；一個節(jié)目中的一個情節(jié)常常由若干幀連續(xù)圖像組成的圖像序列構(gòu)成，一個圖像序列中前后幀圖像間也存在一定的關(guān)系，這種關(guān)系叫做時間相關(guān)性。這兩種相關(guān)性使得圖像中存在大量的冗余信息。如果我們能將這些冗余信息去除，只傳輸少量非相關(guān)信息，就可以很大節(jié)省傳輸頻帶。而接收機利用這些非相關(guān)信息，按照一定的解碼算法，可以在保證一定的圖像質(zhì)量的前提下恢復(fù)原始圖像。一個好的壓縮編碼方案就是能夠較大限度地去除圖像中的冗余信息。激光電視是智能電視比較主流的選擇。鎮(zhèn)江4K數(shù)字激光電視</p><p

style="text-indent:25px">數(shù)字激光電視的信源編譯碼技術(shù)：數(shù)字電視尤其數(shù)字高清晰度電視與模擬電視相比，在實現(xiàn)過程中，較為困難的部分就是對視頻信號和音頻信號的壓縮。數(shù)字電視的圖像不能象模擬電視的圖像和聲音那樣直接傳輸，而是要多一道壓縮編碼工序。視頻編碼技術(shù)主要功能是完成圖像的壓縮，使數(shù)字電視的信號傳輸量由995Mbit/s減少為20～30Mbit/s。與視頻編譯碼相同，音頻編譯碼主要功能是完成聲音信息的壓縮。在HDTV視頻壓縮編譯碼標(biāo)準(zhǔn)方面，都采用MPEG-2標(biāo)準(zhǔn)。MPEG壓縮后的信息可以供計算機處理，也可以在現(xiàn)有和將來的電視廣播頻道中進行分配。鎮(zhèn)江4K數(shù)字激光電視</p><p
