APPENDIX 2—SD WIDE SCREEN SIGNALING
[Subaddresses 0x59, 0x5A, 0x5B]
Rev. 0 | Page 68 of 88
The ADV7320/ADV7321 support wide screen signaling (WSS)
conforming to the ETS 300 294 standard. WSS data is
transmitted on Line 23. WSS data can be transmitted only when
the device is configured in PAL mode. The WSS data is 14 bits
long, and the function of each of these bits is shown in Table 40.
The WSS data is preceded by a run-in sequence and a start
code; see Figure 97. If SD WSS [Address 0x59, 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 s 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 0x61, Bit 7.
