HDMI线多方面的的介绍与用法

date:On February 07, 2018 Source:  

   利用HDMI线材来传输无非就是音视频传输的需要,有线传输介质是指在两个通信设备之间实现的物理连接部分,它将信号从播放设备传输到显示设备上。连接方法大家都知道,用HDMI或者VGA等线材把蓝光机(电脑)和电视(投影机)连接起来。随着无线传输技术的发展,越来越多的人热衷于无线传输的方式。无线传输主要有以下几个方面的优势:使用方便,即插即用,无需安装插件;无需布线,综合成本低,性能更稳定,只需要一次性投资,而布线的话,装修、维护很麻烦。

The use of HDMI cable to transmit nothing more than the need for audio and video transmission, wired transmission media refers to the realization of the physical connection between the two communication devices, it will signal from the playback device to the display device. As we all know, with HDMI or VGA and other wire Blu-ray machine (computer) and television (projector) connected. With the development of wireless transmission technology, more and more people are keen on wireless transmission. Wireless transmission mainly has the following advantages: Easy to use, plug and play, no need to install the plug-in; no wiring, low overall cost, more stable performance, only one-time investment, and cabling, decoration, maintenance is very troublesome.

   随着高清视频产品的普及,传统视频传输方案已经不能满足实际应用需求。H.264高清视频网络传输方案,将1080p全高清视频信号压缩并转换为网络数据,使其可通过网线实现远传输。与传统模拟视频延长方案不同的是,其对高清视频信号使用H.264格式编码压缩,并转为TCP/TP协议的标准网络数据流,将视频信号传送到局域网内任何区域,真正意义上的实现局域网方式传输高清视频信号。H.264方案是业内性价比最优的视频传输方案,可广泛应用于安防监控,楼宇大屏,商场广告,数字看板,可视传媒教学,数字KVM等领域。

With the popularity of high-definition video products, traditional video transmission solutions have been unable to meet the actual application requirements. H.264 HD video network transmission program, the 1080p Full HD video signal is compressed and converted to network data, so that it can be achieved through the network cable transmission. With the traditional analog video extension scheme is different from the high-definition video signal using H.264 format encoding and compression, and converted to TCP / TP standard network data stream, the video signal sent to any area within the LAN, in the real sense LAN way to achieve high-definition video signal transmission. H.264 solution is the industry's most cost-effective video transmission solution, which can be widely used in security monitoring, building large screen, mall advertising, digital signage, visual media teaching, digital KVM and other fields.


   HDMI线是高清晰多媒体接口线的缩写。HDMI能高品质地传输未经压缩的高清视频和多声道音频数据,最高数据传输速度为5Gbps。同时无需在信号传送前进行数/模或者模/数转换,可以保证最高质量的影音信号传送。HDMI可搭配宽带数字内容保护(HDCP),以防止具有著作权的影音内容遭到未经授权的复制。HDMI所具备的额外空间可应用在日后升级的音视频格式中。

HDMI cable is an acronym for high-definition multimedia interface cable. HDMI delivers high-quality uncompressed HD video and multi-channel audio data at up to 5Gbps. At the same time without the need to carry out digital / analog or digital / digital conversion before the signal transmission, you can ensure the highest quality audio and video signal transmission. HDMI works with Broadband Digital Content Protection (HDCP) to prevent unauthorized copying of copyrighted audiovisual content. HDMI has the extra space available in the future upgrade audio and video formats.


   HDMI输出接口的信号源输出到有HDMI输入接口的接收器上。一般来说:有HDMI输出口的电脑就是HDMI信号源,有HDMI输入口的电视就是接收器。电脑与电视通过HDMI线连接起来后,就相当于电视机成了电脑的第二块显示屏。其实目前市面上主流HDMI线材可分为1.4和2.0版本。最为常见的1.4版本HDMI线材即可支持4K分辨率30帧以及3D视频的传输,而2.0版本则对4K超高清视频传输做了优化提升,支持4K分辨率60帧传输,以及色深由1.4版本的8bit提升至10bit。用户在购买时,只是用于观看4K电影,1.4版本足以够用,如果是玩PS4这类高清游戏,2.0版本HDMI线材更适合。(2.0版本支持4K60帧传输,游戏画面更流畅)。

HDMI output signal source output to the receiver with HDMI input interface. In general: a HDMI output computer is the HDMI signal source, HDMI input port of the TV is the receiver. After the computer and the television are connected via the HDMI cable, the television becomes the second display of the computer. In fact, the current market mainstream HDMI cable can be divided into 1.4 and 2.0 versions. The most common 1.4 version of HDMI cable to support 4K resolution 30 frames and 3D video transmission, while the 2.0 version of the 4K Ultra HD video transmission has been optimized to enhance support for 4K resolution 60 frame transmission, and color depth from 1.4 version The 8bit upgrade to 10bit. Users at the time of purchase, just for watching 4K movies, 1.4 version enough to play, if it is to play such high-definition games PS4, 2.0 version of the HDMI cable is more suitable. (2.0 version supports 4K60 frame transmission, the game screen smoother).


   HDMI1.4版在线材上将增加一条数据通道,支持高速双向通讯。支持该功能的互连设备能够通过百兆以太网发送和接收数据,可满足任何基于IP的应用。HDMI网络传输将允许基于互联网的HDMI设备和其它HDMI设备共享互联网接入,无需另接一条以太网线。新功能还将提供一个连接平台,允许HDMI设备之间共享内容。HDMI高清线技术将支持专为数码相机设计的色彩空间,包括sYCC601、AdobeRGB、AdobeYCC601,可在连接数码相机的时候显示更精确的逼真色彩。

HDMI1.4 version of the wire will add a data channel to support high-speed two-way communication. Interconnect devices that support this feature can send and receive data over Fast Ethernet for any IP-based application. HDMI network transmission will allow Internet-based HDMI devices to share Internet access with other HDMI devices without the need for an additional Ethernet cable. The new feature will also provide a connectivity platform that allows content to be shared between HDMI devices. HDMI HD line technology will support color space designed specifically for digital cameras, including the sYCC601, AdobeRGB, and AdobeYCC601, to provide more accurate, realistic color when connected to a digital camera.
