SD WIDE SCREEN SIGNALING
Subaddress 0x99, Subaddress 0x9A, Subaddress 0x9B
The ADV7342/ADV7343 support wide screen signaling (WSS)
conforming to the ETSI 300 294 standard. WSS data is trans-
mitted 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 61. 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.
