APPENDIX 2—SD WIDE SCREEN SIGNALING
[Subaddress 59h, 5Ah, 5Bh]
The ADV7330 supports wide screen signaling (WSS) conform-
ing to the standard. WSS data is transmitted on Line 23. WSS
data can be transmitted only when the ADV7330 is configured
in PAL mode. The WSS data is 14 bits long, and the function
of each of these bits is shown in Table XVII. The WSS data is

preceded by a run-in sequence and a start code (see Figure 57).
If SD WSS [Address 59h, Bit 7] is set to 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.
It is possible to blank the WSS portion of Line 23 with
Subaddress 61h, Bit 7.
