At the time, DVI-HDCP (DVI with HDCP) and DVI-HDTV (DVI-HDCP using the CEA-861-B video standard) were being used on HDTVs. The HDMI founders began development on HDMI 1.0 on April 16, 2002, with the goal of creating an AV connector that was backward-compatible with DVI. and Disney, along with system operators DirecTV, EchoStar ( Dish Network) and CableLabs. HDMI has the support of motion picture producers Fox, Universal, Warner Bros. Digital Content Protection, LLC provides HDCP (which was developed by Intel) for HDMI. The HDMI founders were Hitachi, Panasonic, Philips, Silicon Image, Sony, Thomson, and Toshiba. 3.8.3 Refresh frequency limits for HDR10 video.3.8.2 Refresh frequency limits for standard video.2.2.4 HDMI Ethernet and Audio Return Channel.2.2.3 Consumer Electronics Control (CEC).2.2.2 Transition-minimized differential signaling (TMDS).As of January 2021, nearly 10 billion HDMI devices have been sold.

In Europe, either DVI- HDCP or HDMI is included in the HD ready in-store labeling specification for TV sets for HDTV, formulated by EICTA with SES Astra in 2005. Production of consumer HDMI products started in late 2003. Other than improved audio and video capacity, performance, resolution and color spaces, newer versions have optional advanced features such as 3D, Ethernet data connection, and CEC extensions. Several versions of HDMI have been developed and deployed since the initial release of the technology, but all use the same cable and connector. : §C The Consumer Electronics Control (CEC) capability allows HDMI devices to control each other when necessary and allows the user to operate multiple devices with one handheld remote control device. No signal conversion is necessary, nor is there a loss of video quality when a DVI-to-HDMI adapter is used. III CEA-861 signals carried by HDMI are electrically compatible with the CEA-861 signals used by the Digital Visual Interface (DVI). HDMI implements the EIA/CEA-861 standards, which define video formats and waveforms, transport of compressed and uncompressed LPCM audio, auxiliary data, and implementations of the VESA EDID. HDMI is a digital replacement for analog video standards. High-Definition Multimedia Interface ( HDMI) is a proprietary audio/video interface for transmitting uncompressed video data and compressed or uncompressed digital audio data from an HDMI-compliant source device, such as a display controller, to a compatible computer monitor, video projector, digital television, or digital audio device.
