Y Pb Pr cables are identical to those used for YUV, Y Cb Cr and
RGB cables. They are therefore completely interchangeable. YUV and
YPbPr signals are both referred to as component signals although
the precise format of the signals are different. The interface is
the same for each, namely three wires. The standard cable is a 75
Ohm co-ax cable terminated in RCA plugs for domestic equipment and
BNC connectors for commercial equipment. It is always worth using
good quality cable to avoid losses in the signal. RGB uses the same
three wires but the signal is separated into three separate colors.
Normally, an RGB signal will have additional cables for
synchronisation signals so an RGB interface will often have 4 or 5
connectors.
