NODD (Nexus Orthicon Display Device)

From Wikipedia, the free encyclopedia

NODD (pronounced "noddy"), which stands for Nexus Orthicon Display Device, was the method used for generating identifications for the BBC1 television network from around November, 1969 to February, 1985.

[edit] About NODD

NODD refers to the act of filming an image in black and white and electronically adding color before the image is aired. This makes it very easy for technical crew to manipulate the colors of the image for whatever reason (like a logo revamp). The black and white camera (or cameras) could easily swing to photograph a different picture with the touch of a button.

[edit] NODD and the BBC

BBC1 employed the NODD system in 1969, with the introduction of the famous mirrored globe on November 15 of that year. The NODD system would be used for just about every BBC1 ID until 1982, when it was used for only the BBC1 globe. It would be retired altogether on February 18, 1985, with the death of the mirrored globe model, and the premiere of the Computer Originated World (or COW).

[edit] Trivia

• Contrary to the belief of many, NODD was not called so because the camera could nod in any direction at the push of a button.
