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 ADV7330 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 pat-
tern. A synchronization pattern is sent immediately before and
after each line during active picture and retrace. VSYNC_O/P,
HSYNC_O/P, and BLANK_O/P (if not used) pins should be
tied high during this mode. Blank output is available.
