YUV Formats
***********

YUV is the format native to TV broadcast and composite video signals. It
separates the brightness information (Y) from the color information (U
and V or Cb and Cr). The color information consists of red and blue
*color difference* signals, this way the green component can be
reconstructed by subtracting from the brightness component. See
:ref:`colorspaces` for conversion examples. YUV was chosen because
early television would only transmit brightness information. To add
color in a way compatible with existing receivers a new signal carrier
was added to transmit the color difference signals. Secondary in the YUV
format the U and V components usually have lower resolution than the Y
component. This is an analog video compression technique taking
advantage of a property of the human visual system, being more sensitive
to brightness information.
