Definitions for "Y/C"
The technical description of S-video. The luminance signal, Y, and the chrominance signal, C, are carried on separate signal/ground pairs. Because the Y channel is carried separately, higher bandwidth is possible and color subcarrier crosstalk is eliminated.
The black/white and color video information sent down separate conductors. Format supported on SVHS recorders
