style="text-indent:25px">導(dǎo)播切換臺切換原理：快切。快切是指從某一路電視信號源瞬間切換到另一路電視信號源的過程，在電視屏幕上表現(xiàn)為一個畫面迅速轉(zhuǎn)換到另一個畫面。它是電視節(jié)目制作中使用比較多的切換方式。它是通過視頻開關(guān)實現(xiàn)的。為保證快切的播出質(zhì)量，避免畫面跳動、撕裂或出現(xiàn)切換雜波干擾，必須使切換在場消隱期間進行，也即是使視頻交叉點在場消隱期間發(fā)生狀態(tài)轉(zhuǎn)換。因此，控制視頻開關(guān)的控制電壓包含兩種信號:一種是操作面板.上送來的按鍵信號;另一種是場控脈沖，只有這兩個信號同時作用在視頻開關(guān)上，視頻開關(guān)才會出現(xiàn)狀態(tài)轉(zhuǎn)換。導(dǎo)播切換臺1—4號監(jiān)視器叫做訊道監(jiān)視器。</p><div
