    Different Video and Audio connection cables and types


    [​IMG] Component Video: The signal is split into three parts, luminance information (Y), two channels of color (Pr & Pb) - terminated by three RCA connections (or once in a while with a locking connector called BNC). The best possible connection between components. DVDs store video information in the component form - and so connecting your DVD player to the TV using a component video cable offers the path of least transformation and results in the best quality.

    [​IMG] S-Video: In S-Video, the signal is split two ways - luminance (Y) and color (C) - terminated by a single terminal that looks similar to a computer keyboard/mouse PS2 terminal. Provides a high quality connection.

    [​IMG] Composite Video: The composite video signal combines all information into a single signal path - terminated by a single RCA jack. Provides the last possible quality.


    More on Quality: On a normal direct view TV one may not see much difference in quality between S-Video and component video. But on large screen, RPTV and HDTV the difference will be obvious. If your TV is large RPTV or a HDTV, then you would want to connect using component video cables. If your TV is relatively small (less than 36") direct view TV, S-Video may provide the optimum quality
    AUDIO CONNECTIONS
    [​IMG] Analog - RCA: Most commonly used analog interconnect. Normally available as pairs of cables - Left (white) and Right (red) to connect stereo equipments. Mostly 50-Ohm cables. This is also used to connect the sub-woofer at a line level. The sub-woofer cables can be of a specialty cable - they do not connect the equipments electrically; in this case the cable will also be directional.

    [​IMG] Digital Coaxial /Digital RCA: Digital interconnects used to connect digital equipments such as DVD players. Uses the similar terminal, as the analog RCA cables, but the impedance must be at least 75 Ohm.

    [​IMG] Digital Optical / Toslink: Common optical link between digital components such as DVD, CD and MD players. Made of glass fibers, much thinner than the digital coaxial cables. Has a square plastic connector that often has cover / plug to protect the terminator when not used.

    [​IMG] Balanced / XLR: A fairly large 3-pin locking terminal, used in high-end audio equipments. Commonly seen in microphones power amplifiers to carry balanced line level analog audio signals. Rarely found with different number of pins (2 to 7).

    [​IMG]DB-25: Mostly used in the computer world as the SCSI interface, sometimes used in high-end audio equipments to carry multi-channel signal.


    OTHER AUDIO/VIDEO CONNECTIONS
    [​IMG] VGA/SVGA: A 15 pin D connector most commonly used to connect monitors to computers. Sometimes used in Digital TVs and projectors. Provides the same quality as the Component Video cables.

    [​IMG] BNC: Bayonet style locking connector – used in high-end video equipments and some high definition tuner/receiver.

    [​IMG] F-Type: This is 75-Ohm coaxial cable is most commonly used to connect cable TV feed to your system. Available in both threaded and non-threaded form.

    [​IMG] SCART/Peritel: – A multi pin connector commonly used in European countries to carry both audio/video signals. The same cable/terminal can be used to carry different type of video (RGB, S-Video and Composite) and analog stereo audio signals.

    Some might argue that RGB signals afford even greater purity than Y-PbPr.

    Sorry, this just struck me as very funny.
    Vince, looking forward to your Primer/FAQ being officially posted. I have seen a couple of pieces of it when I look in the "30 most recents posts" section. That's my excuse, by the way. I don't just "hang out" in the testing section like Jack apparantly does! [​IMG]
