Television studio

A professional television studio generally has several rooms, which are kept separate for noise and practicality reasons.

The studio floor is the actual stage on which the actions that will be recorded and viewed take 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.

A transmission control room (TCR) is usually smaller in size and is a scaled-down version of centralcasting.
