What is the HDMI line?


HDMI high definition multimedia interface (High Definition Multimedia Interface) is a fully digitized image and voice transmission interface, which can transmit uncompressed audio and video signals. HDMI can be used in set-top boxes, DVD players, personal computers, TV amusement devices, integrated expansion machines, digital audio and TV sets. HDMI can transmit audio and audio signals at the same time. The same cable is used for audio and video signals, which greatly simplifies the installation of the system.


HDMI interface, like DVI, uses the transmission of all digital signals, but the difference is that HDMI interface can not only provide all digital video signals, but also transmit audio at the same time. It's like returning to the wired RF interface. Just the same is the fact that the use of fully digitalized signal transmission will not lead to poor image quality, like video and audio interference caused by radio frequency. The advantage of the application of HDMI is that only one HDMI line is needed, and the audio signal can be transmitted at the same time, rather than the need for multiple wires to connect. At the same time, higher audio and video transmission quality can be achieved because of the number, mode, mode and number conversion of wireless.
