The function of HDMI cable is mainly reflected in the following two aspects:
1. Connecting set-top box and smart TV
When a family buys a set-top box, it will be randomly matched with an HDMI high-definition cable for signal transmission between the box and the TV.
2. Connecting computer
As a signal transmission cable between smart TV and computer, HDMI cable can transmit uncompressed high-definition video and multi-channel audio data to the TV with high quality. At the same time, there is no need to perform digital/analog or analog/digital conversion before signal transmission, which can ensure the highest quality audio and video signal transmission.
