PRISM MPI-MPX User Manual
•
Video to Reference: The input video signal (SDI or IP) is compared relative to the
reference input (analog or PTP).
•
Analog to PTP: Used in a hybrid system to compare the analog reference to the PTP
reference to ensure synchronization.
Elements of the Timing 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 is
above or to the left of the cross hair. A signal that is late is 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.
– Time: The total difference in frame timing between the input and reference
– 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 ± ½ line for the input format.
– 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.
– 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.
