APPENDIX 2—SD WIDE-SCREEN SIGNALING
[Subaddresses 0x59, 0x5A, 0x5B]
Rev. 0 | Page 68 of 92
The ADV7324 supports 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 bit is shown in Table 40. The
WSS data is preceded by a run-in sequence and a start code (see
Figure 96). 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 after 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.
