•Minimum Latency Frames Control

Minimum Latency Frames Control

When Framesync is enabled, specifies the smallest amount of latency

allowed by the frame sync (latency measurement in output video frames).

The frame sync will not output a frame unless the specified number of

frames are captured in the buffer. The operational latency of the frame

sync is always between the specified minimum latency and

minimum latency plus one frame (not one field).

(Maximum range is 0 to 13.)

Note:Due to card memory limits, the maximum available Minimum

Latency Frames is related to the output video format selected.

For example, with a 1080i59.94 output, the maximum allowed

setting is 5. For a 1080i film (23.98) output, the maximum allowed

setting is 3. Conversely, greater maximum settings are allowed for

SD formats such as 525i59.94, where the practical maximum limit

is 13.

When using this control, be sure to check the Framesync Status

display as follows:

•Latency frames selection within limits.

•Latency frames selection exceeds limits.

• Video Delay Display Displays the current input-to-output video delay (in msec units) as well as

in terms of Frames/fractional frame (in number of lines).

• Framesync Status Display Displays the current framesync status as follows:

•Framesync status OK.

•Framesync Enable set to Off.

•Improper or missing framesync reference.

•Latency frames selection exceeds limits.

Note:See Minimum Latency Frames Control (p. 3-23) f or more

information about this message.

•Loss of Input Signal Selection In the event of input video Loss of Signal (LOS), determines action to be

taken as follows:

•Disable Outputs:Disable all outputs.

•Freeze Last Frame:Freeze image to last good frame (last frame

having valid SAV and EAV codes).

•Freeze to Color:Freeze image to a color raster (as selected using

Framesync LOS Freeze Color control).

Note:If this card is used to also pass embedded audio, note that

audio noise will occur upon loss of input with “Freeze Last

Frame” selected.
