HDMI (High-Definition Multimedia Interface) is a proprietary specification designed to ensure compatibility between video and audio devices over a single digital interface. The specification is used for consumer electronics — including high-definition and ultra-HD TVs, DVD and Blu-ray players, game consoles, streaming devices such as Roku, soundbars, laptops and PCs — as well as for automotive and commercial devices. HDMI cables connect these devices and carry both uncompressed digital audio and video signals over a single cable.
