Wings Insertion Synchronization Example
Figure 3-1 shows an example of using the 9363 to receive a house reference
and provide coincident and a locked offset reference such that wings video
insertion can be delayed, allowing the wings video to align with the program
video, considering the inherent delay of the wings inserter.

In this example, the wings video input to the Wings Inserter device must be delayed by 152 lines in order to compensate for
program video delay inherent in the inserter. The house reference is provided undelayed to the basic reference inputs of the
program video framesync and wings inserter framesync input.
The wings video path here is equipped with its own framesync, which receives the delay offset reference from the 9363, thereby
maintaining a precise, stable offset regardless of any drift in the house reference.
Shown below are the 9363 DashBoard control settings for this setup.
