A transmission control room (TCR), transmission suite, Tx room, or presentation suite is a room at broadcast facilities and television stations around the world.[1] Compared to a master control room, it is usually smaller in size and is a scaled-down version of centralcasting. A TX room or presentation suite will be staffed 24/7 by presentation coordinators and tape operators and will be fitted out with video play-out systems often using server-based broadcast automation.
For operational and content qualitative reasons, not more than two television channels are managed from one TCR. Channels with live content and production switching requirements like sports channels have their own dedicated TCRs. A television station may have several TCRs depending on the number of channels they broadcast.
