Description
Y Two’s complement <-> binary offset conversion
0 = Data at the output of the HD-data path are left unchanged
1 = MSB of data output of the HD-data path is inverted
U Two’s complement <-> binary offset conversion
0 = Data at the output of the HD-data path are left unchanged.
1 = MSB of data output of the HD-data path is inverted.
V Two’s complement <-> binary offset conversion
0 = Data at the output of the HD-data path are left unchanged.
1 = MSB of data output of the HD-data path is inverted.
Enables insertion of R/Y sync signals into the component signals.
0 = Embedded sync is disabled.
1 = Embedded sync is enabled.
Enables insertion of G/U sync signals into the component signals.
0 = Embedded sync is disabled.
1 = Embedded sync is enabled.
Enables insertion of B/V sync signals into the component signals.
0 = Embedded sync is disabled.
1 = Embedded sync is enabled.
Sync signal insertion enable
0 = No insertion of HD sync module generated sync signals - the
external signals are forwarded to the sync ports.
1 = The insertion of HD sync module generated H-sync, V-sync and
Blank signals is enabled. (Note: This disables external sync
signals.)
H-sync is derived from sync value[0].
V-sync is derived from sync value[1].
C-blank is derived from sync value[2].
Enable 422 to 444 up-sampling filter
0 = Filter switched into bypass mode
1 = Filter is active.
DAC6 output level coarse adjustment
DAC5 output level coarse adjustment
DAC5 and 6 output level fine adjustment
0 = Programming via VBI disabled (use this mode for 24-bit parallel
mode and any other mode containing non-656 compliant data).
1 = Programming via VBI enabled
