HDMI线的设计与用途

date:On January 10, 2018 Source:  

   HDMI线设计,在真实使用时效果真的很好,不光可以看清接口,就连接口上的文字都可以看清,音频效果也提升了好几个档,据说还可以热插拔,平常没事的时候我会让男神卸下来,连接机顶盒和电视,看韩剧和电影,效果不输电影院。

HDMI cable design, the effect is really good when in real use, not only can see the interface, even the text on the interface can be seen, the audio effect has also improved several files, it is said that you can also hot-swappable, usually nothing I will let the gods unload, connect set-top boxes and television, watching Korean dramas and movies, the effect is not lost transmission theater.

   还有需要注意的是如果你的视频信号源是4K60hz,显示器的像素分辨率是3840×2160,原来用的1.4及以下版本的HDMI线,现在换了2.0版本的HDMI线,显示质量明显提高是可能的。只要信号源一传递媒介(线)一显示器系统之一不规范,就达不到高质量的图像效果。HDMI高清线主要传输的是数字信号,在市面上的HDMI高清线质量是参差不齐,很多HDMI高清线在传输距离超过10米之后的衰减程度比较严重,而且在选择HDMI高清线的时候一定买合适自己的长度,不要太长,不利于传输。

Also note that if your video source is 4K60hz, the display pixel resolution is 3840 × 2160, the original 1.4 and below versions of the HDMI cable, now replaced the 2.0 version of the HDMI cable, the display quality is significantly improved possible. As long as the source of a signal transmission medium (line) a display system is not standardized, not up to high-quality image effects. HDMI HD line is the main transmission of digital signals in the market, the quality of HDMI HD line is uneven, a lot of HDMI HD line in the transmission distance of more than 10 meters after the attenuation is more serious, and in the choice of HDMI HD line must buy Suitable for their length, not too long, is not conducive to transmission.


   衰减就是HDMI高清线接受设备在多少米能保持信号传输。实际上,衰减在频率越高的情况下,信号会衰减得更厉害。取决于使用什么源设备,如:使用以前的480P的DVD,它的码率低,所以HDMI高清线可以放到35米没有问题。但随着科技的进步,设备码率越来越高,HDMI高清线传输信号会越来越短。

Attenuation is HDMI HD line to accept the device in how many meters can keep the signal transmission. In fact, the attenuation can be attenuated even at higher frequencies. Depending on what source device you are using, like the previous 480P DVD, which has a low bit rate, so the HDMI HD line can be put 35 meters without problems. However, with advances in technology, equipment bit rate is getting higher and higher, HDMI HD line transmission signal will be shorter and shorter.


   光纤HDMI信号传输线,与普通铜线的HDMI线在外观方面看似并无二异,但在长距离传输过程,作为光纤的材质其优越性就体现出来了,根据业内人士的分析,采用光纤取代铜线作为高速信号传输介质,能够在较长的距离下无损地传输4K图像及高保真的音频。

Optical HDMI signal transmission line, and ordinary copper HDMI cable in appearance seems no different, but in the long distance transmission process, as the advantages of the optical fiber material is reflected, according to industry analysis, the use of optical fiber to replace As a high-speed signal transmission medium, copper wire can transmit 4K images and high-fidelity audio losslessly over long distances.
