style="text-indent:25px">壓縮技術(shù)：視頻壓縮技術(shù)（*適用數(shù)位訊號）。自從數(shù)位信號系統(tǒng)被廣fan使用以來，人們發(fā)展出許多方法來壓縮視頻串流。由于視頻資料包含了空間的與時間的冗余性，所以使得未壓縮的視頻串流以傳送效率的觀點(diǎn)來說是相當(dāng)糟糕的?？傮w而言，空間冗余性可以借由“只記錄單幀畫面的一部分與另一部分的差異性”來減低；這種技巧被稱為幀內(nèi)壓縮（intraframe compression）。并且與圖像壓縮密切相關(guān)，而時間冗余性則可借由“只記錄兩幀不同畫面間的差異性”來減低；這種技巧被稱為幀間壓縮（interframe compression），包括運(yùn)動補(bǔ)償以及其他技術(shù)。目前常用的視頻壓縮技術(shù)為DVD與衛(wèi)星直播電視所采用的MPEG-2，以及因特網(wǎng)傳輸常用的MPEG-4。電影藝術(shù)是視頻藝術(shù)中重要的起源類型，是現(xiàn)代科學(xué)技術(shù)與藝術(shù)相結(jié)合的產(chǎn)物。浙江制作視頻收費(fèi)</p><p style="text-indent:25px">錄影藝術(shù)：以電子攝影機(jī)拍攝影像技術(shù)為基礎(chǔ)而發(fā)展出的藝術(shù)形式。蘇州線上視頻網(wǎng)站</p><p style="text-indent:25px">視頻可以用逐行掃描或隔行掃描來傳送，交錯掃描是早年廣播技術(shù)不發(fā)達(dá)，帶寬甚低時用來改善畫質(zhì)的方法(其技術(shù)細(xì)節(jié)請參見其主條目）。NTSC，PAL 與SECAM 皆為交錯掃描格式。在視頻分辨率的簡寫當(dāng)中經(jīng)常以i來表示交錯掃描。例如PAL格式的分辨率經(jīng)常被寫為576i50，其中576 表示垂直掃描線數(shù)量，i表示隔行掃描，50表示每秒50個field（一半的畫面掃描線）。在逐行掃描系統(tǒng)當(dāng)中每次畫面更新時都會刷新所有的掃描線。此法較消耗帶寬但是畫面的閃爍與扭曲則可以減少。為了將原本為隔行掃描的視頻格式（如DVD或類比電視廣播）轉(zhuǎn)換為逐行掃描顯示設(shè)備（如LCD電視，電漿電視等）可以接受的格式，許多顯示設(shè)備或播放設(shè)備都具備有轉(zhuǎn)換的程序。但是由于隔行掃描信號本身特性的限制，轉(zhuǎn)換后無法達(dá)到與原本就是逐行掃描的畫面同等的品質(zhì)。蘇州線上視頻網(wǎng)站</p></p><br
