This allows it to connect the DVD player, receiver and PRR separately with a single

What is an HDMI cable and what does each PIN of an HDMI plug mean?

Most of the units and individuals who use the HDMI standard for research, development and application know the origin of HDMI. In April 2002, seven companies including Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson and Toshiba jointly established HDMI high-definition multimedia. The interface organization began to develop a new digital video/audio interface technology that meets the standards of the high-definition era. After more than half a year of preparation, the HDMI organization officially released the HDMI 1.0 standard on December 9, 2002, marking the official entry of HDMI technology into the historical stage.

As of today, HDMI has come a long way for nearly 15 years, from the earliest 1.0 to the current 2.0, from 1080p to the current 4Kx2K @60Hz, which is a leap.

Smartavlink is committed to the development and application of HDMI active optical fiber (HDMI AOC), HDMI optical fiber extenders and other equipment, and has long-term contact and understanding of HDMI connectors and their PIN pins.
