APPENDIX 5—SD TIMING MODES
[Subaddress 4Ah]
Mode 0 (CCIR-656)—Slave Option
(Timing Register 0 TR0 = X X X X X 0 0 0)
The ADV7310/ADV7311 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 synchroniza-
tion 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.
