APPENDIX 5—SD TIMING MODES
[Subaddress 0x4A]
MODE 0 (CCIR-656)—SLAVE OPTION
(TIMING REGISTER 0 TR0 = X X X X X 0 0 0)
The ADV7322 is controlled by the SAV (start active video) and
EAV (end active video) time codes in the pixel data. All timing
information is transmitted using a 4-byte synchronization
pattern. A synchronization pattern is sent immediately before
and after each line during active picture and retrace. S_VSYNC ,
S_HSYNC , and S_BLANK (if not used) pins should be tied high
during this mode. Blank output is available.
