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.

The functional blocks (the application-specific integrated circuit display driver, 2- and 3D acceleration and video decoding and encoding) are separate semiconductor intellectual property (SIP) blocks on the chip, since hardware devices vary substantially; some portable media players require a display driver that accelerates video decoding, but ...
The EIA/CEA-861-E standard has the first 64 short video descriptors above. It is used by HDMI 1.4–1.4b. The CTA-861-F standard has the first 107 short video descriptors above. It is used by HDMI 2.0–2.0b. The CTA-861-G standard has the full list of 154 (1–127, 193–219) short video descriptors above. It is used by HDMI 2.1.
High-Definition Multimedia Interface (HDMI) is a compact audio/video standard for transmitting uncompressed digital data. There are three HDMI connector types. Type A and Type B were defined by the HDMI 1.0 specification. Type C was defined by the HDMI 1.3 specification.
Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
HDMI connector plugs (male): Type D (Micro), Type C (Mini), and Type A. High-Definition Multimedia Interface (HDMI) High definition digital video devices (HDMI protocol) Electrically compatible with DVI-D and DVI-I, but not DVI-A, using a simple adapter.
In common MHL Alternate Mode implementations, the video from the GPU will be converted to an MHL signal by using an MHL transmitter chip. The transmitter chips often accept video in MIPI (DSI/DPI) or HDMI format and convert it to MHL format. The USB Type-C port controller functions as a switch and multiplexer, passing the MHL signal through to ...
The device driver provides one or more interfaces, for example VDPAU, Video Acceleration API (VA-API) or DXVA for video decoding, and OpenMAX IL or VA API for video encoding. One of these interfaces is then used by end-user software, for example VLC media player or GStreamer, to access the Quick Sync Video hardware and make use of it.
