Camera cable
[Film Technology]
The cable attaching the camera head’s circuits [camera head circuit]to the remainder of its associated
electronic equipment(e.g. camera control unit).
It carries video signals (picture signal), power, scanning
wave forms etc.. The camera cable is vital line between the television camera head and its camera control unit. Function :
To bring the camera out-put of the
camera (the video) from the studio floor to be
electronically processed and then fed to the vision
mixer; and to convey supplies of various types of the camera itself. The different types of wire within camera cable carry various signals and
supplies, including the picture out-put, from
the camera, synchronizing pulses, electrical
power, talk back circuits to the camera, and
specialized voltage feeds to ensure correct operation of the pick-up tube.
The cable inter connecting the camera to its control equipment [CCU/CPU] supplies
voltage and wave forms to the camera, and routes its video for amplification and video
distribution. It may have multi-wire cable/multi core cable[e.g. 100-300m maximum] coaxial cable [e.g. 700-1200 m maximum] or glass fibre strand construction [fibre optics]. The last is lightest, interference free
and robust, allowing considerable distances [e.g. over 4000 m] between a camera
and its control equipment.[in video camera].
