The card is based on the flat roof of pc machine , at first , we are used of the source of program data to leave in ide care , then binary file is come by the send out card , which is transmitted the standard ' s transmission stream . according to the european the standard of dvb - c , variable transmission current velocity rate is 9 . 6 - 38 . 4 mbits / s 此卡基于pc機平臺,首先將節(jié)目源數(shù)據(jù)以二進制文件的格式存放在普通ide硬盤上,然后通過計算機的pci總線將二進制文件經(jīng)過發(fā)送卡轉(zhuǎn)換成符合數(shù)字電視asi (異步串行接口)接口標準的平穩(wěn)碼流。根據(jù)歐洲dvb - c標準,可變的傳送流速率為9 . 6 ~ 38 . 4mbit s 。
