APPENDIX 2–SD WIDE SCREEN SIGNALING
Subaddress 0x99, Subaddress 0x9A, Subaddress 0x9B
The ADV739x supports wide screen signaling (WSS)
conforming to the ETSI 300 294 standard. WSS data is
transmitted on Line 23. WSS data can only be transmitted when
the device is configured in PAL mode. The WSS data is 14 bits
long. The function of each of these bits is shown in Table 54.
The WSS data is preceded by a run-in sequence and a start code

(see Figure 100). The latter portion of Line 23 (after 42.5 μs
from the falling edge of HSYNC ) is available for the insertion of
video. WSS data transmission on Line 23 can be enabled using
Subaddress 0x99, Bit 7. It is possible to blank the WSS portion
of Line 23 with Subaddress 0xA1, Bit 7.
