then the valid adjustment range, with EasySound, is effectively reduced to "0
lines and 17.025µS" through "0 lines and 58.899µS".
Analogue Reference (Black and Burst)
Using the Black and Burst analogue input as reference, the timing and
synchronisation adjustment has to be given a much wider range. B&B signals
have typically been looped through a number of cascaded equipment and
extensive propagation delays are possible. The full range of the adjustment is
from "- 7 lines - 63.666µS" to "+7 lines + 63.444µS". When setting up
Imagestore to operate with the B&B reference, that signal and an analogue
version of a PGM or PVW output signal should be viewed on two traces of
an oscilloscope. View the frame pulse of the each and adjust the timing
setting until the two frame pulses occur within the same line. With this
achieved, view both an analogue copy of the BGnd/A signal and an analogue
output signal. Adjust the propagation delay as described taking care not to
alter the "line" value.
