The high-definition cable is a high-definition multimedia transmission cable, which is called "High Definition Multimedia" in English and abbreviated as HDMI cable. Generally, the HDMI cable contains two parts: interface and cable. The high-definition cable is specially developed for high-definition audio and video equipment. Therefore, he has put forward higher process requirements for interfaces, wires, connectors, and production technology.

1. Use of set-top box and smart TV

When we purchase a set-top box, the box will be randomly equipped with an HDMI high-definition cable for signal transmission between the box and the TV.

2. Computer use

HDMI high-definition cable, as a signal transmission line between smart TV and computer, will transfer the contents of the computer to the smart TV through the HDMI cable.

The HDMI cable is an abbreviation for high-definition multimedia interface cable. It can transmit uncompressed high-definition video and multi-channel audio data with high quality. The maximum data transmission speed is 5Gbps. At the same time, there is no need for digital / analog or analog / digital conversion before signal transmission, which can ensure the highest quality audio and video signal transmission.

The HDMI cable supports a data transmission rate of 5Gbps, and can transmit 30 meters at the farthest, which is enough to cope with a 1080p video and an 8-channel audio signal. And because a 1080p video and an 8-channel audio signal require less than 4GB / s, there is still a lot of HDMI cable. This allows it to connect the DVD player, receiver and PRR separately with a cable
