style="text-indent:25px">導播切換臺是一種專業(yè)的視頻信號導播設備，它的作用非常大，可以直接連接攝像機并且對攝像機傳輸過來的視頻內容進行導播，因為它帶有一個網(wǎng)絡接口，所以可以通過配置RTMP服務器就能直接推送視頻上網(wǎng)。是一種非常方便的網(wǎng)絡直播產(chǎn)品，中山導播臺系統(tǒng)。依據(jù)視頻信號的不同可以分為HDMI導播臺、VGA導播臺、SDI導播臺。導播切換臺自帶網(wǎng)絡接口，可以自主完成導播和推送。導播切換臺需要配置RTMP相關的服務器地址等內容，中山導播臺系統(tǒng)，中山導播臺系統(tǒng)，才能實現(xiàn)視頻推送。導播切換臺其**導播傳輸能力強，因此在相對較大型一點的視頻會議、網(wǎng)絡發(fā)布會等場合與高清攝像機等產(chǎn)品配合使用做網(wǎng)絡直播效果會更好。導播切換臺的預覽總線的按鈕數(shù)量、類型和排列與PGM總線完全一樣。中山導播臺系統(tǒng)</p><div

style="text-indent:25px">導播切換臺與視頻采集卡在進行網(wǎng)絡直播中有什么區(qū)別：1、在視頻采集處理上不同：導播切換臺自帶網(wǎng)絡接口，可以自主完成導播和推送。而視頻采集卡則必須和電腦一起使用才能達到效果2、兩者推送視頻的協(xié)議不同：導播切換臺需要配置RTMP相關的服務器地址等內容，才能實現(xiàn)視頻推送。而視頻采集卡則是直接將視頻采集到電腦再通過軟件來進行推送。3、應用領域不同：雖然兩者都能做網(wǎng)絡直播，但是在使用領域方面也有所不同，導播切換臺其**導播傳輸能力強，因此在相對較大型一點的視頻會議、網(wǎng)絡發(fā)布會等場合與高清攝像機等產(chǎn)品配合使用做網(wǎng)絡直播效果會更好。而視頻采集卡則更適合自媒體朋友們在家做直播、小型的視頻會議等場合。中山導播臺系統(tǒng)對于播出用的導播切換臺，主要應保證工作穩(wěn)定可靠，操作簡便，有應急措施。</p><div

style="text-indent:25px">網(wǎng)絡導播切換臺作用特點：1.全接口支持，支持SDI、HDMI、VGA、CVBS等多種輸入源，對于各種輸入的信號能夠自動識別；2.支持單播、組播及廣播傳輸，支持UDP、RTSP、RTMP、HTTP、TS等多種流媒體協(xié)議，可直接向Flash Media Server、Aoku Media Server、RED5等流媒體服務器推送直播流，通過Windows Media Player，F(xiàn)lash

style="text-indent:25px">導播切換臺-混合：混合也稱為慢切換，可分為X切換和V切換。V切換，即在慢切換過程中，一路視頻信號幅度先由比較大逐漸變小直至為零，然后另一路視頻信號才由零逐漸增至比較大，在屏幕上表現(xiàn)為某一內容的畫面由比較強變淡直至消失，另一內容的畫面才開始出現(xiàn)并逐漸增強。實現(xiàn)V切換，在進行電視信號B取代電視信號A的V切換時，利用黑場信號使V切換轉換成進行兩次X切換。即先進行黑場信號取代電視信號A的***次X切換，然后再進行電視信號B取代黑場信號的第二次X切換。導播切換臺的混合也稱為慢切換。中山視頻導播臺</p><p style="text-indent:25px">從導播切換臺的使用范圍來分類，又可分為播出用的切換臺和節(jié)目制作用的切換臺兩大類。中山導播臺系統(tǒng)</p><p style="text-indent:25px">導播切換臺-鍵信號：鍵信號應該被看作一個視頻信號，并且包含有與它所處理的視頻信號相同的所有信息(復合同步信號、復合消隱信號和色同步信號) ;黑電平表示全透明，白電平表示不透明，黑和白之間的值表示部分透明，電平級差與所處理的視頻信號的電平級差相同。鍵信號的色度分量應該置0。數(shù)字鍵信號的取樣頻率應該與ITU-R601標準中亮度信號的取樣頻率相同，且電平的量化級數(shù)也應該與亮度信號-樣，8比特量化時在16~235級之間，其傳輸接口應該像ITU-R
