HDMI – High Definition Multimedia Interface

The High-Definition Multimedia Interface (HDMI) is an all-digital audio/video interface capable of transmitting uncompressed streams. HDMI is compatible with High-bandwidth Digital Content Protection (HDCP) Digital Rights Management technology. HDMI provides an interface between any compatible digital audio/video source, such as a High Definition Satellite set-top box, a DVD player, a PS3 game system, or AV receiver and a compatible High Definition TV.

DVI – Digital Visual Interface

The Digital Visual Interface (DVI) is a video interface standard designed to maximize the visual quality of digital display devices such as flat panel LCD computer displays and digital projectors. It is designed primarily for carrying uncompressed digital video data to a display, it does not carry Audio.

Component Video

One way of maintaining signal clarity is by separating the components of a video signal so that they do not interfere with each other. When a signal is separated this way it is called 'component video' Y'PbPr signals comprise two or more separate signals.

SCART

SCART is a 21-Pin Connector for connecting Video/Audio Equipment

Originating in France in the late 70’s SCART makes it easy to connect AV equipment (including TVs, VCRs, DVD players and game consoles).It gathers together various common analogue signal types into a single connector, previously, each of these would have had their own socket, requiring numerous separate connections.

The signals carried by SCART include both composite and RGB (with composite synchronisation) video, and stereo audio input/output.
