Juggler and Compere
Juggler and Compere
The concepts behind a pixel processor can may be new to you, so here is an overall picture of how the
key components of a Juggler system 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. Its main component board is a field-programmable gate array (FPGA), which makes it
extremely versatile for performing highly specialised processing tasks. 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.
