Determining The Sync Mode - Sony NU-NM11B System Integration Manual

Determining the Sync Mode

The system supports the following two sync modes. Select the mode according to the application.
• Network InputLock mode
• Network GenLock mode
You can specify a different sync mode for use in each OR.
Note
Set trolley devices that are shared between ORs to the same sync mode as the OR.
Network InputLock mode
In Network InputLock mode, source IP converters become network sync leaders, and the destination IP converters become
followers.
The leader IP converter generates a network sync signal synchronized to the input video signal, and the followers operate
in sync with the network sync signal.
The video signal transmission delay time is shorter because the input video signal and network sync signal are
synchronized.
On the other hand, when switching the video signal transmitted to a destination IP converter, the switching time is longer
because the IP converter must be synchronized with a different leader.
