Ln_Count_Reset
83h
15
Toggle this bit to reset the line-based counters in the
device.
This is only required when locking the
“f/1.001”
HD
output standards to the 525-line SD input reference
standards, or vice-versa, AND:
1. The reference has been removed and subsequently
re-applied. In this case, the user should wait until the
reference has been re-detected by the device, which
may take up to 4 frames. See
Section 3.5.3 on
page 47
.
OR
2. The device is locked to blanking signals from a
deserializer, and the SDI input to the deserializer has
been switched upstream from the system. See
Section 3.6.5 on page 60
