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 µs from the falling edge of HSYNC) is available for the insertion of video.
Function of CGMS Bits
Bit 0–Bit 2
Bit 3 is odd parity check of Bit 0–Bit 2
