What are the different types of video cables?

Answer 1

There are several types of video cables. These types include: coaxial cables, HDMI cables, component video,S-Video, and standard video cables. There are used to connect the various pieces of equipments that we use today.

Answer 2

There are many. Most common of those are:

[ANALOG]

- RF signal -- this is only partially "cable", since the signal is modulated onto a carrying frequency and sent as radio waves (this is the signal your TV antenna picks up)

- Composite Video -- 1 cable, 2 wires - it takes the color (chroma) and brightness (luma) information and mixes them to be sent over a pair of wires; usually uses 1 RCA jack

- S-Video (sometimes INCORRECTLY labled 'Super-Video') -- 1 cable, 4 wires - it takes the color (chroma = C) and brightness (luminosity = Y) information and sends them separately over two pairs of wires; usually uses a special S-Video connector

- RGB video -- three signals are sent over three cables, 2 wires each; each cable sends color information of its type - R for Red, G for Green and B for Blue. Luminosity (brightness) is sent over one of the color channels - usually Green, since it carries the strongest signal and thus "mixing in" the brightness information (in a procedure very much like the mixing done in Composite video, resulting really in a G+Y combination) will have the least impact on picture quality; VGA video is RGB video; usually uses 3 RCA jacks

- Component video -- also called YPbPr - is similar to RGB, but only two colors are sent - Pr for Red and Pb for Blue. Luminosity is sent over a separate channel (the Y). Red isn't sent, since it can be derived from luminosity by substracting the remaining two colors; usually uses 3 RCA jacks

[DIGITAL]

- HDMI - which stands for High-Definition Multimedia Interface - sends video, audio, metadata and copy-protection information in a digital format, that is - encoded into 1s and 0s; out of all the connection types it is the second one to send out signals other than just video (the first being RF antenna signal which combines analog video, analog audio and "semi-digital" teletext)

Note: a SCART connection (also called a EURO in Europe) features lines for both Composite Video and RGB Video in its defined standard. Some TVs/VCRs/Set-Top-Boxes/etc. can use some pins to send/receive S-Video, but this is rarely supported. Component Video can be (and sometimes is) sent over the RGB pins of the SCART connector, but this is non-standard. The standard way, as it was defined in the SCART standard, was to use Composite Video for the video and RGB (with proper blanking) for overlays such as teletext or subtitles (SCART RGB can be displayed with transparency if the video signal is properly blanked).

Answer 3

There are numerous different types of video cabling, all of which will have different uses and depend on the particular requirements of the user. One may require HDMI cables, DVI cables, speaker cables or component cables.
