An umbilical contains all the cables to connect a camera through to the control room for a live show. These are run in parallel inside a flexible plastic sheath, so they should be dead easy to connect up and move around with, without risking tangling everything. | An umbilical contains all the cables to connect a camera through to the control room for a live show.

==2019 replacements== | |||
The fate of the original umbilical set is unknown, although with the changing equipment they probably became redundant or broke, there has been no replacement for at least a few years (as of 2019). There is a plan to update this system and build new versions of the Umbilical for future studio shows. | |||
At this point, the plan follows closely to the original design: Containing. | |||
* XLR 3 pin, for comms | |||
* COAX for camera signal | |||
* 13A power for the converters | |||
* CAT5 possibly for some form of new tally if it ever happens | |||
