What does HDMI Mean?
HDMI (High-Definition Multimedia Interface) is a digital interface that transmits uncompressed video and audio data from a source device, such as a Blu-ray player, DVD player, or computer, to a display device, such as a TV or monitor. HDMI supports multiple video formats, including standard, enhanced, or high-definition video, as well as multi-channel digital audio.
The HDMI interface consists of 19 pins, which are arranged in a Type A connector. Type A connectors are the most common type of HDMI connector and are found on most consumer devices. There are also Type B, C, and D connectors, which are used for specific applications, such as automotive, mobile, and display devices.
