APPENDIX 4
WIDE SCREEN SIGNALING
The ADV7172/ADV7173 supports Wide Screen Signaling (WSS) conforming to the standard. WSS data is transmitted on Line 23.
WSS data can only be transmitted when the ADV7172/ADV7173 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 71).
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
μ
s from the falling edge of
HSYNC
) is available for the insertion of video.
