The ADV7194 supports Wide Screen Signalling (WSS) conform-
ing to the standard. WSS data is transmitted on Line 23. WSS
data can only be transmitted when the ADV7194 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 97. 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.
