BRTN TV1

1st ID (1977-1987)
Visuals: On a background, there is the RTBF logo in  and to the left of the screen. On the right is the same text from the last logo, but in a more modern-looking font.

Variant: At closedown, the text is replaced with an triangle that looks like a slash. It's also smaller.

Technique: None.

Audio: Same as the BRT logo.

2nd ID (1977-1991)
Visuals: On a black background, a small square appears in the middle of the screen. It then slowly zooms in, which then folds open to reveal an diamond. It then opens up again to reveal a brown square, in which the BRT logo fades onto. It consists of "brt" in a very odd font with the RTBF logo attached to the left side.

Variant: At closedown, the logo reverses.

Technique: The zooming and opening.

Audio: A warbly synth tune that repeats in different pitches, with several harpsichord notes throughout.

Availability: This was BRT's logo at the time, and was used at closedowns and startups.

3rd Logo (January 1, 1982-July 10, 1986)
Visuals: On a black background, a white outline of a "1" is seen with several trails coming of it. Copies emerge from it and zoom towards the screen, 4 in total, before it zooms towards the screen as well. The logo then fades to the same "1" on a dark blue background, filled with a light blue. The background fades to black, revealing trails going to the bottom left as "brt" fades in to the right of it.

Variants:
 * Sometimes, the logo may be still and in 3D.
 * The logo can be still.

Technique: The copies zooming in, the logo fading.

Audio: A series of rising drones are first played, followed by a harpsichord tune with synths. A drone play when "brt" fades in.

4th ID (July 11, 1986-1998)
Visuals: At sunset, there is a skyline of Brussels, with several buildings in the distance as well as the Reyers Tower and Atomium. Then, all of them light up one by one. The skyline then fades out to a black background with a dark blue glow as an line wipes in, revealing a flashing "brt" in it as well. When the line finishes, an outline of the BRT TV1 logo in zooms out with a trail effect, before the trail zooms in and flashes. This forms the logo in with a grid design similar to that of the BRT 2 logo inside it. The 1 shines and sparkles around the edges.

Technique: The footage, the rolling and peeling.

Audio: Same as before, but remixed to feel more powerful.

Visuals: On a black background, 2 bars fly into view before slowly folding over. As they fold over, the camera rotates to face the top of them, revealing a dark gray cloth in the background. When the bars fold over themselves, they form a abstract "1" that zooms in with the background.
