Media Sequencer Redundancy
This section describes the operation of the main/backup switching of the Media Sequencer. It is possible to select the Main or Backup Media Sequencer, from within Viz Mosart, however there may be a delay of several seconds after switching from one to the other, before the Media Sequencer responds to Viz Mosart commands.
The diagrams below show the configuration and operations possibilities of the various components in the Media Sequencer backup concept. The gray arrows show which operations are available in each Viz Mosart module.
Switching Media Sequencer from the GUI
Switching between main and backup Media Sequencer is normally done in the Viz Mosart GUI. In the bottom right corner, you will find the text: Use backup Graphic Controller. This text is clickable and switches Viz Mosart to the backup Media Sequencer. Subsequently, the text changes to Use main Graphics Controller on a yellow background, to visibly alert you to the exceptional state.
During the switching process, the alarm indicators in AV Automation momentarily goes red, but goes back to green when the switching process is finished.
Still, the Media Sequencer needs some additional seconds to initialize all parts, so it is recommended to wait some time before continuing graphics operations. The exact delay varies with graphics size and complexity.
Configuration and Test
Use the fields marked in red to configure the use of two Media Sequencers; one main and one backup.
Note: In AV Automation, in the field MSE Host, specify the two IP addresses (one for each Media Sequencer) separated with a semicolon (';'). In Trio Interface, there are separate input fields for these addresses.
Use the check box Use MSE backup marked in blue if you want Viz Mosart to start on the backup Media Sequencer after a restart.
Test and Debug
Both Trio Interface and AV Automation have a separate menu item that enables you to switch each of them between the main and backup Media Sequencer. This switching possibility is just for testing and debugging purposes. It is recommended to use the main switch in the GUI instead.
Note: The yellow background of the GUI Media Sequencer indicator only follows the setting of the AV Automation Media Sequencer selector. The corresponding selector in Trio Interface does not affect this indicator.
