Video Cables

Analog video connection choices are Composite Video, S-Video, VGA, and Component Video. Not all of these connections are present on all equipment. A standard VCR may only have a composite connection, whereas a DVD player may provide for composite video, s-video, or component video connections.

Digital video connection choices may include DVI, and or HDMI Video. DVI carries video only. DVI is used on computers, set-top-boxes, and display devices such as HD Plasma or LCD flat monitors, projectors, or DVD players, particularly those with up-conversion to HD resolution. HDMI cables carry video, audio, and control signals over one cable. HDMI is now being used on set-top-boxes, home theater receivers, and HD flat panel display devices, and projectors.

Please verify the input/output options available on your equipment. Your equipment may not accept every type of cable and/or connector.

Composite Video (Analog Signals)
Composite video cables transmit all the signals required for color video including luminance (brightness) and chrominance (color) information. Composite video cables typically use one RCA, F-Type, or BNC connector at each end of the 75 ohm coaxial cable used to hook up the video signal source to the display. On your video equipment the connectors are usually color coded yellow and may be labeled video, CVBS, composite, or baseband. Composite Video is standard on all DVD players.

S-Video or Y/C (Analog Signals)
S-Video (Y/C) provides a better quality picture than composite video. S-video splits the signal into luminance (black and white information) and chrominance (color information). S-Video typically uses 4-pin DIN connectors at each end of the cable and is comprised of two 75 ohm coaxial cables. Most DVD players have s-video output.

Component Video (Analog Signals)
Component Video provides even better picture quality than either composite video or s-video. Component video cable is comprised of three 75 ohm coaxial lines which each transmit one of the three parts of the video signal. Component video subtracts the luminance (brightness) signal from the subcomponents of the chrominance signals (blue and red signals), and is often described as Y, R-Y, B-Y or as YpbPr. Component video connections are found on newer DVD players and HDTV systems.

RGB Video (Analog Signals)
RGB video also provides better picture quality. RGB video uses 15 pin connectors with multi-channel video cable. RGB video is typically found on projector systems.

DVI Video (Digital Signals)
DVI (Digital Video Interface) carries uncompressed video data, and offers the highest quality digital picture. DVI cables are used to connect any HD display that utilizes the DVI input interface, and are compatible with HDMI video. DVI video does have somewhat of a limited length ability, however all the lengths of DVI that we carry are tested and fully DVI compliant.

HDMI Video & Audio (Digital Signals)
HDMI (High Definition Multimedia Interface) carries video, digital audio, and control data, and offers the highest quality digital picture along with sound. HDMI cables are used to connect any HD display that utilizes the HDMI input interface, and are compatible with DVI video, if the DVI is HDCP enabled. HDMI supports nearly 5 Gbps, which is more than sufficient for High Definition DTV at its highest resolution.
