S-Video
Separate Video (2 channel), more commonly
known as S-Video and Y/C, is an analog
video transmission (no audio) that
carries standard definitionvideo typically
at 480i or 576i resolution.
Video information is encoded on two
channels: luma (luminance, intensity, "Y")and chroma (colour, "C").

DV
DV is a format for storing digital video.
DV video employs interlaced scanning withthe luminance sampling frequency of
13.5 MHz. This results in 480 scanlines per
complete frame for the 60 Hz system, and 576
scanlines per complete frame for the 50 Hz
system.

Serial Digital Interface
Serial digital interface (SDI) is a family
ofvideo interfaces standardized
by SMPTE (The Society of Motion Picture and
Television Engineers).
The various serial digital interface standards
all use (one or more) coaxial cables with BNC
connectors, with a nominal impedance of75 ohms.

HDMI
HDMI (High-Definition Multimedia Interface)is a compact audio/video interface fortransferring uncompressed video data and
compressed/uncompressed digital audio datafrom an HDMI-compliant device ("the sourcedevice") to a compatible digitalaudio device, computer monitor, video
projector, or digital television. HDMI is adigital replacement for existing analogvideo standards.

DVI
Digital Visual Interface (DVI) is a video displayinterface and used to connect a video sourceto a display device, such as a computer
monitors and digital projectors. DVI's digital video transmission format is
based on PanelLink
PanelLink uses transition minimizeddifferential signaling (TMDS), a high-speedserial link developed by Silicon Image..

DVI and HDMI Comparision
HDMI is a newer digital audio/video interface developed and
promoted by the consumer electronics industry. DVI and HDMI have
the same electrical specifications for their TMDS and VESA/DDC links.
However, HDMI and DVI differ in several key ways.
HDMI lacks VGA compatibility. The necessary analog signals areabsent from the HDMI connector.
DVI is limited to the RGB color space. HDMI supports RGB, but also
supports YCbCr 4:4:4 and YCbCr 4:2:2. These spaces are widely used
outside of computer graphics.
HDMI supports the transport of packets, needed for digital audio, in
addition to digital video. An HDMI source differentiates between a
legacy DVI display and an HDMI-capable display by reading the
display's EDID block.
