APPENDIX 4
WIDE SCREEN SIGNALING
The ADV7192 supports Wide Screen Signaling (WSS) conforming
to the standard. WSS data is transmitted on Line 23. WSS data
can only be transmitted when the ADV7192 is con
fi
gured in PAL
mode. The WSS data is 14-bits long, the function of each of these
bits is as shown below. The WSS data is preceded by a run-in
sequence and a Start Code, see Figure 97. The bits are output
from the con
fi
guration registers in the following order: C/W20 = W0,
C/W21 = W1, C/W22 = W2, C/W23 = W3, C/W24 = W4,
C/W25 = W5, C/W26 = W6, C/W27 = W7, C/W10 = W8,
C/W11 = W9, C/W12 = W10, C/W13 = W11, C/W14 = W12,
C/W15 = W13. If the bit C/W07 is set to a Logic 1, it enables
the WSS data to be transmitted on Line 23. The latter portion of
Line 23 (42.5
μ
s from the falling edge of
HSYNC
) is available for
the insertion of video.
