COMMON VIDEO SIGNALS
Computer: The most common computer video resolutions today are 640 x 480 thru 1920 x 1200. The signal consists
of red, green, blue, horizontal sync and vertical sync (RGBHV).
Composite: Composite video is the video format of an analog television signal before it is combined with sound and
modulated onto an RF carrier. Composite video is the combination of luminance and chrominance on a single cable.
This is typically the signal type you get from a camera or the “video out” on the back of a VCR or DVD. The most
common formats used around the world are NTSC, PAL, or SECAM. NTSC is the US standard.
S-Video: S-Video means “Separate Video”. It is also called Y/C video. Y/C video is an analog signal that carries the
video data (luminance and chrominance) as two separate signals.
COMMON VIDEO CONNECTORS
HD15: The common 15-pin VGA connector found on most video cards, computer monitors and other devices is
almost universally called “HD-15”. HD stands for “high-density”, which distinguishes it from connectors having the
same form factor but only two rows of pins. The HD connector has three rows of five pins.
BNC: The BNC connector is a type of RF connector used for terminating coaxial cable and is commonly used for
video connections of both analog and SDI video type interfaces.
RCA: The RCA jack is a commonly used connector in audio/visual and can be used for both composite video and line
level audio.
DB13W3: The DB13W3 is an analog video interface connector and can be converted into standard VGA connector
using cables and adapters that are commonly available.
RJ-45: The RJ-45 is an eight-wire connector used commonly to connect computers onto a local-area networks (LAN)
especially Ethernets.
