External Reference
When an external Reference signal is applied to the frame (e.g. 525 or 625 Black, HD tri-level Sync),
and the proper Reference Input has been selected for the board, and the Reference is being
detected as
‘Present’
and
‘Locked’,
and the SDI channel’s field-or frame-rate matches the rate of the
Reference signal
Video- and embedded Audio-data will be processed and synchronized to the applied Reference.
The
Frame Sync / Mux Status
menu will report channels set to
Frame Sync: Sync Mode
as
Frame Sync: Ext Lock
.
Reference present and locked, different frame rate for SDI channel
When a Reference is present and locked, but the SDI channel’s field or frame rate doesn’t match the
rate of the Reference signal
The channel will be automatically forced into
Delay
mode.
The
Frame Sync / Mux Status
menu will report channels set to
Frame Sync: Sync Mode
as
Frame Sync: Delay Rate Mismatch
.
Frame Sync: Delay Mode
Note: In
‘Delay’
mode, only a restricted set of processing features can be applied to an SDI channel.
When operating the Frame Sync in
Delay
mode, the audio embedders are automatically turned off. Any
ancillary data will be passed unprocessed (aside from any video delay).
If the input video frame rate does not match the genlock frame rate for a channel, that channel is
automatically placed into
Delay
Mode. This information is reflected in the Frame Sync Status parameter.
An SDI channel can be forced into Delay mode operation by setting it to
Frame Sync: Delay Mode
.
Channels set to
Frame Sync: Delay Mode
will be reported as
Frame Sync: Delay Forced
by the
Frame Sync / Mux Status
menu.
Bypass Mode
In
Bypass
mode, the SDI channel will bypass all processing stages.
No Framesync operation and no Audio muxing takes place when operating a channel in
Bypass
mode.
The Frame Sync / Mux Status menu reports channel forced to operate in
Bypass
mode as
Bypass
.
