Y/C Separation Signal Output Connector
The Y/C separation signal output connector is an S connector used to transmit composite
signals. The connector transmits signals when the output format is composite (see Table 12-3,
“List of output connectors”).
The output connector diagram and pin arrangement are given below.

When the output format is NTSC-J, a DC voltage that indicates the aspect ratio, as defined by
JEITA, is superimposed on the color signal output given in Table 7-8. The ID signal
specifications are given below. The ID signal is fixed at 0 V when the output format is not
NTSC-J.
