TCX Video

(1981-1986)
Visuals: On a navy blue background, a pair of black boxes wobble outwards to reveal the logo: in white and in diagonal formation, white cursive letters "T.", "C.", "X." and a white word "video", with word "video" being smaller than the letters. Underneath the script text, we see a white word "Presents" in white sans-serif text.

Technique: Grass Valley 300 production switcher effects.

Audio: A sequence of four high xylophone notes and three low xylophone notes, repeated twice.

Availability: It can be seen on a lot of adult British pre-cert tapes from their company.
