Composite Video - Standard Connectors

Standard Connectors

In home applications, the composite video signal is typically connected using an RCA jack (phono plug), normally yellow. It is often accompanied with red and white connectors for right and left audio channels respectively. BNC connectors and higher quality coaxial cable are often used in professional television studios and post-production applications. BNC connectors were also used for composite video connections on early home VCRs, often accompanied by either phono connector(s) or a 5-pin DIN connector for audio. The BNC connector, in turn post dated the PL-259 connector which featured on first generation VCRs.

In Europe, SCART connections are often used instead of RCA jacks (and to a lesser extent, S-Video), so where available, RGB is used instead of composite video with computers, video game consoles, and DVD players.

Video cables are 75 ohm impedance, low in capacitance. Typical values run from 16 pF/ft for an HDPE-foamed dielectric precision video cable (e.g. Belden 1694A) to 21 pF/ft for a solid PE dielectric cable (e.g. Belden 8281 or Canare LV-77S).

    A disposition to preserve, and an ability to improve, taken together, would be my standard of a statesman.
