DashBoa rd™ shows
Framesync Status error
message in UPC-166
Framesync function
submenu screen.
Specified Minimum Latency
Frames setting exceeds UPC-
166 card buffer space for the
selected output video format Reduce the Minimum Latency Frames setting
as specified in the error message to correct the
error.
Note: Due to card memory limits, the maximum
available Minimum Latency Frames is
related to the output video format selected.
For example, with a 1080i 5994 output, the
maximum setting is 5. For a 1080i film
(2398) output, the maximum setting is 3
(due to the increased buffer space needed
for the slower frame rate). Conversely,
greater maximum settings are allowed for
SD formats such as 525i 5994, where the
practical maximum limit is 13.
