The word video means "I see" in Latin. But how will you be able to see captured, recorded, processed, stored, transmitted, or reconstructed images? You use video display devices such as televisions or monitors, of course. But all these would not be made possible without the use of video cables. Video cables are wires that transmit video signals. To help you understand more, here are the different types of video cable.
- BNC Cables. The BNC or Bayonet Neil-Concelman connector is a type of connector that uses radio frequencies in the multi-megahertz range. It is often used in place of a coaxial cable. There are a lot of consumer electronic devices with RCA (Radio Corporation of America) jacks that you can use with a BNC cable, but you have to use adapters to be able to do so. You will mostly find it being used for analog signals, Serial Digital Interface signals, and electronic devices used for aviation, or as antenna connectors for amateur radios. BNC cables come in both 50 and 75 ohm.
- Component Video (RCA, RGB). The RCA connector is the most common cable used by audio/video electronic devices. It usually comes in three colors. Red for the right channel, white for the left channel, and yellow for the composite video. The RGB or red-green-blue connector is a type of connector that has pin-outs. It is commonly known as VGA cable. You will mostly find it being used with video cards, monitors, or HDTVs. It is more commonly known as a VGA connector.
- HDMI, DVI, DisplayPort Cables. The HDMI or High-Definition Multimedia Interface connector is a cable that transmits digital data. It is the digital version of RF cables, RCA or RGB cables or S-Video cables. You will mostly find it being used on cable converter boxes, BD or Blu-ray Disc players, computers, Playstation 3s, or Xbox 360s. The DVI or Digital Visual Interface cable is a connector that transmits uncompressed digital video data. You will mostly find it being used on flat screen or LCD monitors, or digital projectors. The DisplayPort cable, developed by the Video Electronics Standards Association is HDMI's strongest competitor. It uses more advanced technology in comparison to the other types of video cables. Companies like AMD, ATI, Genesis Microchip, Samsung, Dell and Apple commonly use DisplayPort cables for their products.
- M1 Cables. The M1 cable is a video connector that can transmit digital, analog, or USB (Universal Serial Bus) signals. It is commonly known as EVC or P&D cable. You will mostly find it being used on new models of projectors.
- S-Video Cables. The S-Video or Separate-Video cable is a connector that can transmit analog signals in lumen (luminance) and chroma (color). It carries videos that are normally at 488i or 576i resolution. You will mostly find it being used on televisions, DVD players, and new versions of cassette recorders, digital receivers, digital video recorders, game consoles, or video cards.
- CCTV Cables (Siamese/Power). The Siamese cable is a connector that can transmit both power and data through a single connector. The Power cable is a connector that can only transmit power data. Siamese and Power cables are used in CCTV or closed-circuit television. You will mostly find them being used in surveillance or monitoring cameras.
- Composite Video Cables. The composite video cable is a connector that can only transmit analog signal. It has three types, NTSC, PAL, or SECAM. You will mostly find it being used on VCRs, game consoles or computers that were modeled during the 1980s.
- HDTV Breakout Cables. The HDTV cable is a connector that is mainly to transmit signals for televisions that are using high definition broadcasting.
- RF Cables (F-Type, Coaxial). The F-type cable is a connector that is used to transmit satellite television or data over cable modems. It is often used with a splitter for use in cable televisions. The Coaxial cable or coax is a connector that is used to transmit signal for home video devices or networking in computers. Long coaxial cables are also used for amateur radios.
Video cable is essential to all sorts of technology. It makes it possible to relive captured moments, or witness things without the need to be physically there. Technology will never cease to amaze us. As it advances, more things are made possible each day.
