Component Video Cables Technical Information.

Component Video Cable

Component video is a video signal that has been split into two or more components.
Most commonly refers to an Analog video information that is transmitted or stored as three separate signals.
Component Video 3 Triple Cables do not carry any audio Signal.
Two formats of component Video Exist with some confusion.

RGB analog Component Video.
Which is simple color component of R-Red, G-Green, B-Blue usually sent along with a sync Signal.
  • Composite sync, where the horizontal and vertical signals are mixed together on a separate wire (the S in RGBS)
  • Separate sync, where the horizontal and vertical are each on their own wire (the H and V in RGBHV) ------->RGBHV is today the Most Popular Computer interface sometimes called a SVGA Signal<-------
  • Sync on green, where a composite sync signal is overlaid on the green wire (SoG or RGsB).
    This is the format used on most Video Equipment using High Definition Video in Analog format.
    Y'PbPr analog component video
    Cable is color coded GREEN=Y' BLUE=Pb and RED=Pr
    Almost all Component TV and DVD and Video Projector Etc. today put the SYNC on the GREEN hence Y'

    Cable Construction for Component Cables.
    Properly made Component Cables. Use triple 75ohm Coax Wire.
    These can be molded separately or in one bundle with Micro Coax Cable.
    Common names for this cable type are RG-59 and RG-6 and Micro Coax RG59
    When bundling in Single Cable Multiple additional out side shields are used.
    Example: Three layers of shielding: two 80%+ OFC copper braids and one 100% overlapped Mylar foil
    Higher %Percentage braid increase RF and EMI Rejection and Cost to Build.
    Center Wire Construction can be of one of these types:
    Listed from Least expensive to Most expensive.
    Resistance goes down as the Price goes up.
    Aluminum Core Copper Clad.
    Solid Copper.
    Copper with Silver Clad.
    Solid Silver.
