style="text-indent:25px">激光電視的編碼壓縮方法：降低采樣頻率。降低采樣頻率能夠壓縮碼率，但是，奈奎斯特采樣定理指出，當取樣頻率（fs）小于基帶頻率（fm）的2倍時，頻譜發(fā)生重疊，則采用低通濾波器無法無失真地恢復原信號。由于電視圖像信號的能量主要集中在以行頻及其各次諧波頻率為中心的較窄范圍內(nèi)，中間存在很大的空隙，因此，若把取樣頻率選為半行頻的奇數(shù)倍，就可使fs<2fm時出現(xiàn)的頻譜混迭部分形成半行交錯。于是，可以采用梳狀濾波器將其選出以較小的失真恢復原始信號。湖南透性激光電視激光電視畫面的清晰度也會隨著色彩飽和度的提高有較大幅度的提升。</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。標準數(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：空間相關性和時間相關性。一幀圖像內(nèi)的任何一個場景都是由若干像素點構成的，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系，這種關系叫做空間相關性；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成，一個圖像序列中前后幀圖像間也存在一定的關系，這種關系叫做時間相關性。這兩種相關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。</p><p style="text-indent:25px">激光電視使用紅、綠、藍三基色固態(tài)激光器作為系統(tǒng)光源，或使用單色固態(tài)激光器激發(fā)熒光粉作為系統(tǒng)光源，或使用固態(tài)激光器結合LED作為系統(tǒng)光源的混合技術投影光源。壽命長。它的室溫壽命一般可達2.5萬小時以上，相比傳統(tǒng)投影機的燈泡壽命的3000小時有了很大提升，完全滿足電視使用壽命的需要。安全性。激光電視中的紅綠藍三色可見光激光光束是經(jīng)過的擴束整形設備后再投射到屏幕上的，人眼觀看到的發(fā)光圖像已經(jīng)是柔和光線，不會對人眼造成傷害。智能激光電視帶給了用戶更便捷的體驗。</p><div
