Bus Connections in a Juggler System
The Juggler bus can be configured in two ways: as a 4-lane ‘half’ bus via SFP modules, or a an 8-lane
‘full’ bus with MPO connectors (see: Connect a Juggler Data Bus ). In Compere this makes no
difference to configuration, and the bus is automatically detected.
A further option is a high-bandwidth configuration of the 8-lane bus, in which lanes 4 and 8 share their
capacity with the other six.
Juggler bus bandwidth is UHD (3840 × 2160) at 60fps 10bpc 444 capable (or equivalent bandwidth)
per bus lane. The high-bandwidth option (6-lane) is capable of 4K.
A juggler System is a group of 2 or more Jugglers on a data bus. In Compere, any input can be sent
onto the bus and redirected to another Juggler module to be picked up there as an input, to process
and direct onto a display. This configuration is stored in the Project file.
The Bus connection block is represented inside the Juggler in the Nodes panel of Compere.

8-Lane Bus
24 or 30 bpp – (30 bpp limited to UHD at 60 fps or equivalent)
There will typically be only one bus in a Juggler, but two are possible. The number of pins in the bus
are those available lanes on the installed bus. Any Juggler can then place up to four video channels
on the bus, and receive up to four as inputs. See in the diagram below how Jugglers interconnect, and
the bidirectional flow of the bus itself, indicated by the pointers of the green pins.
