When you have understood how and why the Output Canvas Bus works, the Wizard can take you through all required settings for a new project.
The workflow for an OCB system is similar to that for an input bus system (see Workflow: Create a Juggler System) but the wizard will set up the canvas and make the bus and output connections for you. It will also automatically switch you into OCB mode.
Preparation Checklist
✓The Juggler system, inputs, outputs and bus, is fully wired.
✓You will already have configured your network, Project Group membership and Project Group server.
✓All required Jugglers in the Project Group appear in the Project panel.
✓You have added all these Jugglers to the Nodes panel, set up their Rx and Tx EDIDs, connected video inputs to sources, and (optionally) renamed them in some way to easily identify their roles, especially those you want to be video channel leaders.
Step 1: The Canvas
Context: see Canvas: Configure a Display.
This part of the wizard will create your basic display configuration in the Project, and requires that there is no Canvas already in the Project panel. It will not delete, reset or edit an existing canvas. Once created, the normal advantages of naming your canvas outputs and windows apply, so that you can easily identify all the elements and match them to any system schematic drawing. |
Enter the overall canvas size, the number of canvas outputs (paired, so double width) and their arrangement (e.g. 3 × 3, 4 × 2, 1 × 4).
•Enter the common resolution for all the canvas outputs (double the width to accommodate the pairing on the bus).
•The number of windows is less important; these can be added and changed afterwards. This will simply add a number of unconfigured canvas windows, or none.
•If your bus is a 4-lane (‘thin’) bus, check ‘Dual Stream’ to create the paired outputs. This is unnecessary for 8-lane (‘full’) bus systems.
•Click ‘Create Canvas’.
Notes:
Each OCB output is per video channel and comprises a pair of ‘Left’ and ‘Right’ parts. The above example has a 2 × 2 arrangement.
•You can close the Wizard for now.
•Drag the new Canvas into the Canvas panel.
•At this point, it can be very helpful to rename your canvas outputs, for example by their location (Top Left, Top Middle etc.).
•Add, name, position and resize any canvas windows now if you wish, but this can be done at any time later. Windows are not invoked by the OCB wizard.
Step 2: Connecting Jugglers to the bus
This part of the wizard connects all Jugglers connected to a canvas, and assigns up to four Jugglers to provide the Tx ports out for each canvas output.
•Reopen the wizard.
•Ignore any default numbers appearing in the canvas section – you will not be using this again.
•Select all Jugglers that are on a common bus.
•Select the bus they belong to (typically this will be Bus:1).
•If necessary, select the EDID for the Tx and Rx ports that the Leader Jugglers use.
•Now assign a Leader Juggler to each active video channel, up to four. If you have named these Jugglers already (as in this example) this will help.
•Select the named canvas output to attach to each of the bus video channels. Every non-lead Juggler will be given the same association between canvas output name and Video # Output. (In the illustration below, every Juggler will have ‘Top Left’ in its Video#1 Output, ‘Bottom Left’ in its Video#2 Output, and so on.)
•Select the two Tx ports on each Video Channel Leader that connect the left/right pair of the canvas output to output devices:
•Click ‘Apply Juggler Settings’. Updating Jugglers is not instant: you will see an alert to give a moment before proceeding further.
•Close the wizard.
•All Jugglers are now addressing the same Canvas, and their video channel outputs correspond to those of the Leaders.
Step 2: Add, configure, assign windows
This step is the same as in the final manual workflow step in Output Canvas Bus, above.
•Whether you added windows via the wizard or not, now make sure you have all the windows you need for the project, name them, size and locate them.
•For each Juggler video channel with an input, in Video # Processing select the window on which to display the media:
