The role of TV HDMI interface

To tell the truth so far, what is the use of HDMI in TV? I believe many people do not understand, HDMI's full name is High Definition Multimedia Interface (High Definition Multimedia Interface), is a digital video / audio interface technology. Its role is as follows:

Advantage 1: Easy to use

HDMI is the only interface that can transmit both uncompressed HD video and uncompressed multi-channel audio at the same time. This means that users can use only one cable to replace several previous audio and video cables. As an easiest example, in the past, users at least required audio and video cables for TV and DVD to work together. Now, only one HDMI high-definition cable is required, which greatly reduces the number of cables and wiring. Difficulty. Currently, the length of conventional HDMI high-definition cable in the market is about 2-3 meters, but some big brands are still “a higher level,” like Ruiteng recently launched a HDMI high-definition connection up to 10 meters line. Undoubtedly, this will make the user's wiring easier and clearer, especially when the user wants to add equipment or change the living room layout.

Advantage 2: Quality + sound quality, double boost

For video, the HDMI interface supports all HD formats including 720p, 1080i, and 1080p. Because of the non-compression technology, its transmission speed is as high as 3.95Gbps. In addition, HDMI is a digital interface, that is, all analog connections are not lost when converting from analog to digital, so it can provide very good video signals, and this difference is particularly noticeable at higher resolutions (such as 1080p). Of course, if you want to achieve the best viewing results, users also have to choose the HDMI high-definition cable. At present, the HDMI1.3 version has the highest usage rate of HD lines, but the HDMI 1.4 version, which includes 2K*4K resolution, 3D Over HDMI, etc., launched by Ruiteng and other brand manufacturers in the year has set off a technical hurricane on the wire market. Attracted many HD enthusiasts sought after.
