date:On September 28, 2017 Source:  

   自从HDMI接口不停的发展结果来看,越高数字的版本会发展的更好,可是以往的电视机出现的都是HDMI1.4的接口,那不是淘汰了吗。HDMI2.0接口,然后还出了HDMI2.0 线,这可是对于厂商的一种痛苦,也是买家的一个无奈啊,这个是什么原因导致的呢?

Since the HDMI interface, the development of non-stop results, the higher the number of versions will develop better, but the previous TV are HDMI1.4 interface, it is not eliminated? HDMI2.0 interface, and then out of the HDMI2.0 line, which is a pain for the manufacturers, but also a helpless buyers ah, this is what causes it?

HDMI2.0接口,HDMI2.0 线

   看了看HDMI2.0接口的属性就知道了。目前对于可以输出4K分辨率的HDMI接口的版本可为2.0是最为完美的,这个怎么说,就是HDMI2.0版本的标准接口可以向下兼容HDMI2.0以下的版本罗,其实重点在于新的4K电影也已经采用更高的帧率来制作,所支持的帧率已经提升到50p、59.94p、60p,甚至是120p。如著名导演彼得•杰克逊拍摄的《魔戒》前传——《霍比特人》便采用了48帧技术,HDMI1.4标准并不支持这些帧率下的4K信号。另一方面,HDMI1.4也仅能支持8位色彩,并不能真实发挥4K视频所采用10位色深的显示优势。

Looked at the HDMI2.0 interface to know the property. Currently available for 4K resolution HDMI interface version can be 2.0 is the most perfect, how to say that HDMI2.0 version of the standard interface can be backward compatible with the following version of HDMI2.0, in fact, the focus is on the new 4K The film has also been used to create a higher frame rate, the support of the frame rate has been raised to 50p, 59.94p, 60p, or even 120p. Such as the famous director Peter Jackson shot the "Lord of the Rings" prequel - "Hobbit" will use 48 frames, HDMI1.4 standard does not support these frame rate under the 4K signal. On the other hand, HDMI1.4 can only support 8-bit color, and can not really play 4K video using 10-bit color depth display advantage.


   此外,在家庭影院系统中,高品质音频流的数据量甚至要大大超过视频信号,因此对音频信号的支持也是很多人非常关注的。HDMI2.0具有更强大的音频特性,支持多音频流和最高1536kHz的音频采样率,另外还支持动态自动声画同步,有效避免音画不同步的问题,所以说HDMI2.0更具有可观性的标准,选购电视首选HDMI2.0的标配。

In addition, in the home theater system, high-quality audio stream data even more than the video signal, so the support of the audio signal is also a lot of people are very concerned about. HDMI2.0 has a more powerful audio features to support multi-audio streaming and up to 1536kHz audio sampling rate, in addition to support dynamic automatic sound and picture synchronization, effectively avoid the problem of non-synchronized audio and video, so HDMI2.0 more observable Standard, buy TV preferred HDMI2.0 standard.
