What is the Full Form of HDMI?

2 minute read

High-Definition Multimedia Interface is the full form of HDMI. To guarantee interoperability between audio and video devices via a single digital interface, HDMI is a proprietary protocol. Consumer gadgets such as high-definition & ultra-HD TVs, DVD and Blu-ray players, game consoles, streaming media players like Roku, soundbars, laptops, and PCs, as well as automotive and business equipment, employ the specification. These devices are linked by HDMI cables, which transmit raw digital video and audio data over just one cable.

The physical, electrical, and communication protocols that makeup HDMI specifications determine how cables and devices interact physically, how much power a cable may carry, and what signals are delivered through cables to enable communication between two pieces of equipment.

In December 2002, the initial HDMI specification was published. It was created by Vantiva, Panasonic Group, Sony Group Corp., Lattice Semiconductor Corp., and Maxell Ltd. The organisation chosen by HDMI Forum, HDMI Licencing Administrator Inc. (HDMI LA), is responsible for licencing the specification.
