M512-3 Juggler : User Guide

Juggler and Compere

For a first-time user, the concepts of the pixel processor can seem a bit confusing, so here is an

overall picture of how the key components work together.

Why Juggler?

Juggler is not just a standalone rack module. We imagine it as stage performer in an event, where as

many Jugglers and other performers as you want can join, take part, or leave, all under the direction

of a Compere, or stage manager that holds the event together.

Juggler is a modular hardware base for full high-bit depth pixel-based colour processing, warp and

blend. It accepts a scalable number of inputs and delivers a scalable number of outputs, in many

protocols. 2D, passive and active stereo 3D are fully supported.

With latency reduced to an absolute minimum, Juggler is ideal for live performance. All sources can

be genlocked to frame accuracy, with instant system failover across all connected devices via frame-

data monitoring (an API is available for third-party sources).

Compere

Compere (pronounced ‘KOM pair’) is the software system that manages all Juggler connections in a

‘stage set’ (we call it the Project Group), defines inputs, outputs and manages displays. A version of

Compere runs in every Juggler on a Linux OS that drives the front panel touch display and

communicates with the FPGA.

Compere provides the user interface (UI) for a Juggler system. Here you create Project Groups of

Jugglers and configure all the inputs and outputs of each Juggler involved. All group activity can then

be managed via external control from multiple network points.

Compere does much more, but for configuring your Juggler system with its media inputs and display

outputs, you need to become familiar with the Juggler side of Compere.

Connect up your hardware before you venture into Compere. Once that is done, connect into the

system from a workstation control PC with Compere running, and every part of the system will be

recognised and identified, along with all their available ports, in order to create the relationships

between each Juggler, their input sources and output devices.

Projects and Groups

Projects are a bit like stage sets, with scenery and equipment ready for a play or show. When you

create or see a Project in Compere, you will see a list of what belongs together for the ‘stage set’:

Jugglers, projectors, 3D models and so on, that are assigned as a Project Group.
