Framesync

Provides video frame sync/delay control and output
control/loss of program video failover selection controls.

• Framesync Enable/Select

Selects Frame Sync functions from the choices shown to the left and
described below.

Free Run: Output video is locked to the card’s internal clock. Output

video is not locked to external reference.

Lock to Reference: Output video is locked to external reference

received on the frame reference bus using the rules selected.
(External reference signals Reference 1 and Reference 2 are
distributed to the card and other cards via buses on the frame.)

Note: If valid reference is not received, the

indication appears in the Card Info

status portion of DashBoard™, indicating invalid frame sync
reference error.

Lock to Input: Uses the program video input video signal as the

reference standard.

Note: If Lock to Input is used for framesync, any timing instability

on the input video will result in corresponding instability on
the output video.

• Initial Startup Format Select

Selects a synthesized frame sync format/rate to be invoked (from the
choices shown to the left) in the time preceding stable lock to external
reference.

Set this control to that of the intended external reference to help ensure
smoothest frame sync locking.

• Program Video Output Mode Select

Provides a convenient location to select between card program video
output and other technical outputs from the choices shown to the left and
described below.

• Input Video – card outputs input program video (or loss of signal

choices described below).

• Flat Field (Black) – card outputs black flat field.
• Freeze – card outputs last frame having valid SAV and EAV codes.

• Test Pattern – card outputs standard technical test pattern (pattern

is selected using the Pattern drop-down described below).

• Loss of Input Signal Selection

In the event of program input video Loss of Signal (LOS), determines
action to be taken as follows:

Disable Outputs: Disable program video SDI outputs.
• Flat Field (Black) – go to black flat field on program video output.

• Freeze – go to last frame having valid SAV and EAV codes on

program video output.

• Test Pattern – go to standard technical test pattern on program

video output (pattern is selected using the Pattern drop-down
described below).
