APPENDIX 4—WIDE SCREEN SIGNALING (WSS)
The ADV7174/ADV7179 supports WSS, conforming to the
standard. WSS data is transmitted on Line 23. WSS data can
only be transmitted when the ADV7174/ ADV7179 is
configured 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 58).
The bits are output from the configuration 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 μs
from the falling edge of HSYNC) is available for the insertion of
video.
