Sync Mode
– Use the
Sync Mode
parameter to set the system-clock source, whether internal
or external. This allows setting the encoder’s system clock synchronization to the internal
Ellipse clock (user-configured), an external synchronization clock source or to Genlock. Select
the sync mode from the following options:
❑
Internal Clock
– Clock source is internal (the internal clock is set through the Date/Time
menu) (Default)
❑
Sync to Video
– Clock source is external.
❑
Genlock
– Synchronization information is embedded in the SDI of the input video stream.
NOTE:
When working with pass-through audio schemes you must set the Sync Mode to Sync to Video
If for any reason the Ellipse cannot detect an external source, the Ellipse displays a Sync-Clock Error message
and returns to its internal clock source.
In audio pass-through encoding, this error causes malfunction in the audio bit-stream.
