RTB1 is the oldest free-to-air terrestrial television channel in Brunei. The channel officially began broadcasting on 1 March 1975.

RTB1 broadcasts for 18-hours from 06:00 until 00:00 BST followed by a satellite simulcast of RTB4 International filling the rest of its broadcasting time.

During non-operating hours RTB1 simulcasts with RTB4 International from 00:00 until 06:00 BST.

RTB1 mainly shows documentaries, educational programs and news in its 18-hour broadcast to programs from RTB4 International which are usually relayed for other times when it is not broadcasting.



Radio Brunei was launched on 2 May 1957, and officially opened on 28 May. At the time, Radio Brunei broadcast for 45 minutes each evening, from 20:00 until 20:45 BST. The range of the single 1.2Kw transmitter was only five miles, which covered the capital and some surrounding areas.

As of 1974, RTB had increased its staff to 171 employees, and had a total of three transmitting sites. This gave near total coverage of the country and beyond.[citation needed]


Televisyen Brunei was officially launched on 1 February 1975 as Channel 5 and Channel 8.

On 1 March 1976, two high-power medium-wave stations in the Brunei-Muara District began transmission, expanding the coverage of radio and television services to almost 100% of the country.
