RTB Perdana (Jawi: ڤردان RTB ‬) (formerly known as RTB1) is the oldest free-to-air terrestrial television channel in Brunei. The channel officially began broadcasting on 1 March 1975.

 

RTB Perdana broadcasts for 18-hours from 06:00 until 00:00 BST followed by a satellite simulcast of RTB Sukmaindera filling the rest of its broadcasting time.

 

During non-operating hours RTB Perdana simulcasts with RTB Sukmaindera from 00:00 until 06:00 BST.

 

RTB Perdana mainly shows documentaries, educational programs and news in its 18-hour broadcast to programs from RTB Sukmaindera which are usually relayed for other times when it is not broadcasting.

 

On April 11, 2017, RTB1 along with sister station, RTB5 merged and renamed RTB Perdana as part of RTB's rebranding project as well as broadcaster's shift from analogue into digital broadcasting.
