Elements of the Timing
application display
•
Path 1 and Path 2
: Displays the IP video format if an IP input signal is
selected.
NOTE.
You can switch between Path 1, Path 2, or both Path 1-2 using the Path
button at the top right of the application display.
•
Master ID
and
Domain
: Displays the reference Source and Domain.
•
PTP Time
: Time of day derived from the PTP signals.
•
Protocol
: Displays the input protocol.
•
Ref Lock
: A
(check in green) indicates the PRISM is locked to the
reference. A
(x in red) indicates the PRISM is not locked to the
reference.
•
Reference Indicator
: A cross-hair indictor centered in the display represents
the reference signal.
•
Circle
: The circle represents the timing of the input signal. A signal that is
early will be above or to the left of the cross hair. A signal that is late will be
below or to the right.
•
Offsets
: The difference in timing between the input and reference. A
positive number, or "delayed" value, means the input occurs after the
reference. A negative number, or "advanced" value, means the input occurs
before the reference.
o
Time
: The total difference in frame timing between the input and
reference
o
Pixels
: The timing difference between the reference and input signal,
expressed as in pixels, instead of time units, after the vertical offset
has been removed. This has a range of +-1/2 a line for the input
format.
o
Vertical Offset
: The timing difference between the reference and
input signal, expressed as the number of lines of delay for the input
video format. This has a range of +-1/2 field for progressive signals
and +-1/2 frame for interlace signals.
o
Horizontal Offset
: The timing difference between the reference and
input signal, expressed as the line time which remains from the total
delay after the vertical offset has been removed. This has a range of +-
1/2 a line for the input format.
