AO
When the Vaddis 778 outputs composite (SCART or non-SCART) video, this line is CVBS output
When the Vaddis 778 outputs RGB, this line is the Green output
When the Vaddis 778 outputs YUV, this line is the Y output
AO
When the other Vaddis 778 output are not SCART video, the output on this line can be either CVBS or C / the
selection is independent of the specific selection of the other three DACs
