SD WIDE SCREEN SIGNALING
Subaddress 0x99, Subaddress 0x9A, Subaddress 0x9B
The ADV739x supports wide screen signaling (WSS) con-
forming to the ETSI 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. The
function of each of these bits is shown in Table 60. The WSS
data is preceded by a run-in sequence and a start code (see
Table 60. Function of WSS Bits

Figure 105). 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.
