hdmi是什么意思?HDMI接口想必很多用户都不陌生,随着智能电视盒子的普及,越来越多的家庭都通过HDMI高清线来连接电视盒子和电视,广泛应用于智能电视、机顶盒、投影仪等等。HDMI全称是高清晰度多媒体接口,英文全称High Definition Multimedia Interface。

详细介绍hdmi:
通俗一点来说,HDMI就是一种高清视频接口,在现在主流笔记本、液晶电视、显卡以及主板中都比较经常可以见到。HDMI是一种数字化视频/音频接口技术,可以同时传送音频以及影像信号。是现在最为流行的高清接口。HDMI是数字信号,而普通的VGA是模拟信号。模拟信号衰减达到一定程度就会有重影情况,在这一点上是远远比不上HDMI的哦。
1、最早的HDMI 1.0版本
2002年12月新推出了最早的HDMI 1.0版本,它最大的特点就是整合了音频流的数字接口了,与当时PC页面中流行的DVI接口相比,它更为先进,也更加方便。HDMI 1.0版本支持从DVD到蓝光格式的视频流且具备CEC功能。在应用时,可以在所有连接设备间形成一种共通的联络,从而更加方便的控制整个设备组。
2、HDMI 2.0
经过很多年的发展,现在我们比较常用的HDMI接口主要是HDMI 2.0。它的宽带扩充到了18Gbps,支持即插即用以及热插拨,支持3840*2160分辨率以及最高支持60Hz帧率。同时在音频方面支持最多32个声道,以及最高1536khz采样率。顺便提一下:HDMI2.0并没有定义新的数据线以及接头、接口,因此对于HDMI 1.x,可以完美向下兼容等等。
3、支持8K的HDMI 2.1
而最新的HDMI 2.1是在2017年1月新推出的,频宽大幅提升至 48Gbps,可以支持高达7,680 × 4,320/60Hz(8K/60p)的影像,或4K/120Hz的更高帧率影像。且支持新的动态HDR技术,比起“静态”HDR,“动态”HDR 可以确保视频的每一幕、甚至每一帧,都显示出景深、细节、亮度、对比度的理想值以及更宽广的色域等等。
总结:
1、最早的HDMI 1.0版本;
2、HDMI 2.0;
3、支持8K的HDMI 2.1。
