Component Video

Component Video is also called YPbPr, or YCbCr and transmits the picture information in a luminance and phase-opposite chrominance pair over three coax cables [Red, Green, and Blue]. RGB [Red, Green, Blue] is some times also called Component Video, but combine the color, black and white signal

YPbPr is 'sometimes' used when discussing the three-wire analog video component interface EIA-770 [EIA-770.2-a SMPTE-240M and others]. The luminance (Y) is represented separately from the color components (Pb and Pr).
In some cases The Y output is provided as a Green jack, the Pb is provided as a Blue jack, and the Pr is provided as a Red jack. The 'Y' signal carries the black and white information, The 'Pb' and 'Pr' signals carry the color difference signals.

YCbCr is used when discussing a digital component interface ITU-601 or ITU-656 digital interfaces (formerly CCIR-601, CCIR-656). Y is Luminance, Cb is Blue Chromanance, and Cr is Red Chromanance. CCIR-601 defines an 8-bit DIGITAL 2's compliment coding for component video

RGB is the component format in which the primary colors (red, green, and blue) are transmitted as three independent components. The color, black and white signals are combined within these three signals. Only using RGB inputs requires separate horizontal and vertical sync inputs. RGB presents a better [TV] signal than the other forms of Component video, S-Video, Composite Video, or RS-170. RGB sends each signal on a separate cable and does not mix the color signals.

Composite Video

Single "Yellow" (shielded) RCA jack [75 ohm coax cable], which is not to be confused with the Audio (Red and White) jacks of the newer three cable systems, or just a single black wire in the older systems. It's a composite of the black-and-white information (Y) and the color information (C). Composite Video may also be called VBS [Video, Blanking and Syncs], or CVBS [Color, Video, Blanking, and Sync]. S-Video is better than Composite Video, and Component Video is better than either of them.

DVI

Digital Visual Interface [DVI] .. standard for high-speed, high-resolution digital displays. Developed by the Digital Display Working Group (DDWG).

Refer to the DVI page for additional info and connector pinout, signal names and a description {This web site}

Digital Video Broadcasting/Digital Audio-Visual Council (DVB/DAVIC), developed by DAVIC and DVB and adopted by European Telecommunication Standards Institute (ETSI) and International Telecommunication Union (ITU)

DVI has a number of different types connectors:
DVI-D Digital only connector; 24 pins [modified D style]
DVI-I Digital and Analog [RGB]; 29 pins [modified D style]
DFP Digital only connector

SCART

SCART: Euro-Audio/video connection system to BS 6552:1984 (EN 50-049). Provides the physical and electrical interconnection between two pieces of audio-visual gear. May also be called "Euro", or "Perri" connector. The SCART connector pinout is shown in the table below

SDI

Serial digital interface [SDI] standard is based on a 270 Mbps transfer rate, over a single 75 ohm coaxial cable, up to 600 feet. Serial Digital Interface is a digital broadcast television standard providing digital encoding of standard NTSC and PAL formats, with embedded audio. SDI is used in Television stations, cable channels, and professional production Equipment. Refer to the SDI page for more information.

S-Video

S-Video [Super-video] sends video signals over a multi-wire cable, dividing the video information into two separate [75 ohm coax or twisted pair cables] signals: one for luminance (Light) 'Y' and one for chrominance (Color) 'C'. Each signal is sent shielded, inclosed in a 4-pin Mini-DIN. S-Video is synonymous with Y/C "Component" video. However Y/C is the correct term, but the term S-Video is widely used to indicate the interface when in fact refers to a VCR tape format.
"S-video is a consumer form of component video used primarily with Hi8 and S-VHS".

High Definition Multimedia Interface, Refer to the HDMI page.
The High Definition Multimedia Interface HDMI cable supplies both high-definition video and multi-channel, digital audio for consumer Audio Visual [AV] entertainment equipment [HDTV, Amplifiers]. The HDMI interface is all digital, with no analog signals. HDMI is backward compatible with the DVI interface, but without the more advanced upgrades and no audio. Converters for HDMI to DVI cables are being produced. The HDMI cable is 5 meters in length and uses 28 AWG wire.
