APPENDIX 4
WIDE SCREEN SIGNALING
The ADV7190/ADV7191 supports Wide Screen Signaling (WSS)
conforming to the standard. WSS data is transmitted on Line 23.
WSS data can only be transmitted when the ADV7190/ADV7191
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 91.
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 trans-
mitted 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.
