9.3.2 External Control Synchronization

Synchronization can also be done from an External Control Application. The following

command has to be sent to the Viz Engine which has the memory map populated:

• From a Command Interface

VIZ_COMMUNICATION SYNCHRONIZE_TO <engine port>

where the Viz Engine is the engine which receives the data through the Command

Interface. Thgerhare port is usually 6100 (standard command interface port).

Note: Vizrt do not recommend this as a method for synchronization.

• Through TCP Communication

VIZ_COMMUNICATION SYNCHRONIZE_SMMTCP <engine port>

where the Viz Engine is the engine which receives the data, and the port is the one

that was specified for incoming TCP key|value pairs on the Viz Engine which is to

recieve the data (see TCP Protocol).

• Through UDP Communication

VIZ_COMMUNICATION SYNCHRONIZE_UDP <engine port>

where the Viz Engine is the engine which receives the data, and the port is the one

that was specified for incoming UDP key|value pairs on the Viz Engine which is to

recieve the data (see UDP Protocol).

9.3.3 Command Synchronization

Another communication option is by Commands. Here each map entry is synchronized

through commands.

It is reliable, but very slow and blocks the engine for quite an amount of time, if the

map is large.

Note: Vizrt do not recommend this as a method for synchronization.

To synchronize a Start-up Viz Engine with Commands

1. Go to the Configuring Viz.

2. Click on Communication.

3. Click on the Shared Memory tab.

4. In the Shared Memory panel set these parameters:

• Master Engine Port: Enter the communication port of the Master engine

(default is 6100).

• Master Poll: Click on Commands.

5. Click Save.
