decoration and/or sets
stage lighting rigs and the associated Lighting control console,
several video monitors for visual feedback from the PCR
a small public address system for communication
television crew work on the studio floor.
the on-screen presenters themselves, and any guests -
a floor manager, who has overall charge of the studio area stage management,
one or more camera operators who operate the cameras
a teleprompter operator, especially if this is a live television news broadcast
Production control room
The production control room is the place in a television studio in which the composition of the outgoing program takes place. The production control room is occasionally also called a studio control room (SCR) or a "gallery" – the latter name comes from the original placement of the director on an ornately carved bridge spanning the BBC's first studio at Alexandra Palace, which was once referred to as like a minstrels' gallery.
The vast majority of devices in a PCR are interfaces for rack-mounted equipment that is located in the Central Apparatus Room (CAR).
The central apparatus room (CAR) houses equipment that is too noisy or runs too hot to be located in the production control room (PCR). It also makes sure that coax cable, SDI cable, Fibre optic cable or other wire lengths and installation requirements keep within manageable lengths, since most high-quality wiring runs only between devices in this room. This can include the actual circuitry and connections between:
character generator (CG)
camera control units (CCU)
digital video effects (DVE)
vision mixer (video switcher)
