HDMI线

   HDMI之前并没有版本之分,比如HDMI1.1和HDMI1.3版本的线缆都是一样的,不过在HDMI1.4版本中,线缆出现了一些变化。HDMI1.4版本中包含了5种类型的线缆,各有其不同的功能与效能特性。HDMI1.4版本分为标准HDMI线缆、标准附以太网络功能HDMI线缆、车用HDMI线缆、高速HDMI线缆、高速附以太网络功能HDMI线缆五种。标准HDMI线缆是支持1080p,高速HDMI则支持包括4k×2k、3D视频、DeepColor等先进显示技术,这种线缆其实就是以前的HDMI1.3版本,它们的带宽需求都在HDMI1.3版本所能提供的带宽以内。而高速附以太网络功能HDMI还有专用的数据通道,也就是提供设备间网络功能的HDMI以太网络通道,线缆的构造就发生了变化。而HDMI2.0接口,最大的特点就是传输速率有了很大的提升,把每条通道的带宽从3.4Gbps上升到6Gbps,从而可以传输更高分辨率的视频和音频,支持更高帧率的4K超高清视频,并且增加了一系列新的功能与特性。在HDMI的标准中,还详细规定了这五类线缆的认证标签。HDMIForumInc.还特别指出,HDMI2.0并不会取代HDMI1.x,而是基于后者的增强,任何设备要想支持HDMI2.0必须首先保证对HDMI1.x的基础性支持。
