Introduction
BBG-1022-FS Functional Description
Figure 1-3 Timecode Processor
Frame Sync Function
This function provides for frame sync control using an external looping
reference signal, or the input video as a frame sync reference. This function
also allows horizontal and/or vertical offset to be added between the output
video and the frame sync reference.
Frame sync can select from either the external frame reference source,
free-run, or input video sync. Selectable failover allows alternate reference
selection should the initial reference source become unavailable or invalid. In
the event of input video loss of signal, the output can be set to disable video,
go to black, go to an internal test signal generator pattern, or freeze to the last
intact frame (last frame having valid SAV and EAV codes).
An internal test signal generator provides a selection of various standard
patterns such as color bars, sweep patterns, and other technical patterns. The
test patterns can be applied to the output video upon loss of input or manually
inserted at any time.
When licensed with option
+2FS
, this function enables a
second independent video/framesync path in which the input and output
crosspoints supply two video paths to and from the dual processing paths.
