视频接口将换代?63%用户看好USB 3.0(1)

视频接口将换代?63%用户看好USB 3.0

2011年1月21日  来源:ZOL  编辑:阿非  

 

而随着USB接口发展到第三代,其速度传输方面有了革命性的提升,并且普及仍在加速中。那么USB 3.0接口究竟会不会成为未来的视频接口,进而取代目前凌乱繁多的传统接口?

 

    目前使用到液晶显示器中的视频接口,其种类十分丰富,相信即便是不是很了解的消费者,也能够轻松的列举出一部分。最传统的主要分为色差分量接口、D-Sub(VGA)接口、DVI(DVI-D、DVI-I等)接口,而近年来十分流行的新兴应用视频接口主要是HDMI(目前主要为HDMI 1.3、HDMI 1.4等)接口、DisplayPort接口和USB 2.0接口。但是从上面介绍的内容来看,其实已经有大部分的视频接口无法满足目前液晶显示器产品画面的传输的需求了。

     目前的液晶显示器产品,无论是分辨率方面的发展(目前单一屏幕的30英寸宽屏液晶显示器的分辨率已经高达2560×1600,如果采用拼接使用,那么分辨率将会呈倍增加),还是目前的显示效果的发展(诸如3D画面的显示),一般的色差分量接口、D-Sub接口、DVI接口和USB 2.0接口根本无法应对如此大的内容传输。

    而在目前的视频接口中,HDMI和DisplayPort接口拥有超大的传输速度和强有力的稳定性,但是大家往往会忽略一个重要的因素,那就是成本。从目前的市场中来看,搭载了HDMI接口或者DisplayPort接口的液晶显示器产品在售价上都要比同规格比例的机型高出至少两百元左右。而这两个接口大部分情况下也只会出现在高端显示器产品中,因此并不能够符合绝大多数消费者的购买预算需求,也就是说它们目前的状态是叫好不叫座,拥有无数的“粉丝”,但是相关产品的销量却没有什么起色。

    面对目前这些种类繁多的视频接口所处在的窘境中,寻找出一个能够取代它们的全新接口类型,看来是势在必行了。但是对于这个接口的要求十分苛刻,它不仅要拥有低廉的成本,还要拥有便携性、高带宽、高传输速率,看来目前的接口中只剩下USB 3.0接口能够满足需求,但是它会替代现在的视频接口吗?
