HDMI (High-Definition Multimedia Interface) is a fully digital audio-video transmission standard designed to simultaneously transmit uncompressed high-definition video, multi-channel audio, and control signals through a single cable to display devices. Since its introduction, it has become the mainstream interface for connecting high-definition devices in consumer electronics, professional audio-visual, and industrial fields.
HDMI employs TMDS (Transition Minimized Differential Signaling) technology to encapsulate video, audio, and auxiliary data into digital signals. This eliminates interference and distortion inherent in analog signals, ensuring pristine picture and sound quality.
HDMI connectors are categorized into three types based on device size and application: Standard HDMI, Mini HDMI, and Micro HDMI.
