Cable. Coaxial. Passband. Typically 0–4 GHz. The BNC connector (initialism of "Bayonet Neill–Concelman") is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It is designed to maintain the same characteristic impedance of the cable, with 50 ohm and 75 ohm types being made. It is usually applied for video ...
RF connectors ( radio frequency signals). Generally use coaxial cable types such as RG-6 and RG-59 (except for twin-lead). Belling-Lee/IEC 169-2 connector. TV aerial plug (a.k.a. antenna plug) Television antenna connection for most video devices outside North America.
The various serial digital interface standards all use (one or more) coaxial cables with BNC connectors, with a nominal impedance of 75 ohms.This is the same type of cable used in analog video setups, which potentially makes for easier upgrades (though higher quality cables may be necessary for long runs at the higher bitrates).
A VGA connector. Video connectors carry only video signals. Common video-only connectors include: Component video aka YPbPr (3 RCA or BNC; or D-Terminal) Composite video (1 RCA, Antenna socket, or BNC) DB13W3 ("13W3" computer video connector) DMS-59, single connector carrying two DVI and two VGA
BNC connectors were also used for composite video connections on early home VCRs, often accompanied by either RCA connector or a 5-pin DIN connector for audio. The BNC connector, in turn, post dated the PL-259 connector featured on first-generation VCRs. Video cables are 75 ohm impedance, low in capacitance. Typical values run from 52 pF/m for ...
The use of BNC RGB video cables predates VGA in other markets and industries. Within a 15-pin connector, the red, green, and blue signals (pins 1, 2, 3) cannot be shielded from each other, so crosstalk is possible within the 15-pin interconnect. BNC prevents crosstalk by maintaining full coaxial shielding through the circular connectors, but ...
A balun is also used on the video recorder end to convert back from the 100 Ω balanced to 75 Ω unbalanced. A balun of this type has a BNC connector with two screw terminals. VGA/DVI baluns are baluns with electronic circuitry used to connect VGA/DVI sources (laptop, DVD, etc.) to VGA/DVI display devices over long runs of CAT-5/CAT-6 cable.
A 15-pin VGA connector for a personal computer A 21-pin SCART or JP21 connector for a television. The various RGB (red, green, blue) analog component video standards (e.g., RGBS, RGBHV, RGsB) use no compression and impose no real limit on color depth or resolution, but require large bandwidth to carry the signal and contain a lot of redundant data since each channel typically includes much of ...
