Technique: The stripes forming.

Audio: A synth 12-note motif tune that repeats every time, with piano notes starting with the appearance of the words.

Logo (1987-1997)
Visuals: On a black background, a blue right triangle comes in from the top of the screen and flies down. More right triangles then come in, forming a large square with a hole in the middle. A single square, containing the words "DELTA VIDEO", comes in from the right of the screen, and flips in to fill the hole. The full square then flips around to show the logo as the triangles fly away, revealing a blue/tannish background.

Technique: The trangles flying and the Delta square flipping in.

Audio: A relaxing synth tune, with several different synth sounds playing as well.

Availability: Appeared on releases from the company at the time.
