5.1 Video Pattern Mode Example

The following table lists the step for a Video Pattern Mode example with two exposures. Start with the system powered on and displaying a video source in Video Mode.

Note: An error occurs if an attempt is made to switch to Video Pattern Mode if there is not a video source with a sync lock.
Note: If the receiver source is switched to another source while in Video Pattern Mode (such as from HDMI to DisplayPort, or RGB input) video sync lock is lost requiring a return to video mode from RGB source to regain sync lock before returning to Video Pattern Mode.
Note: The total exposure time of patterns defined within an input video frame cannot exceed the total frame time or a Sequencer Abort Error occurs. Therefore, when a sync occurs, if all of the exposures defined within that frame are not finished the sequencer aborts and a sequencer error is thrown. The sequencer attempts to resume on the next frame following the aborted frame.
