The Noddy video camera was servo-controlled to pan and tilt ('nod') across a matrix of pre-arranged physical objects - captions and mechanical models. The camera was black-and-white, with electronically synthesised colour added to its output. This system eliminated the delay associated with swapping graphics upon a conventional copy stand. It also allowed for the depth required by mechanical objects such as clocks and a rotating globe.
The BBC first employed the system in the 1960s, before the advent of colour. The system's remote operation allowed the operator to control it with ease, and allowed the idents to be of no fixed length as the clock symbols could continue for many minutes at a time. A smaller black and white camera was introduced as camera technology progressed and, from 1969, a process was introduced to add colour signals to the camera output. This electronic addition of colour was convenient and made the networks' rebrands easy to perform.
The BBC1 mirrored globe
The most famous idents of the Noddy system were the BBC1 mirrored globes used between 1969 and 1985, albeit with minor colour changes. The system machinery consisted of an internally lit, rotating globe in front of a concave mirror. The oceans were painted onto the globe in metallic black paint, leaving the land masses as unpainted patches. The original globe ident introduced on 15 November 1969 featured blue continents and legend against a black background. The legend included the word 'COLOUR' after the BBC1 corporate logo, to identify the new programme format and act as an advertisement to the vast majority of viewers, still watching in black and white: the colour version of the television licence which financed the BBC was much more expensive. The colours of blue and black were chosen because they were still easily distinguishable to those with black and white televisions. Another version of the globe without the 'Colour' legend was used before black-and-white programmes, of which there were still many in the BBC1 schedule in the early 70s.
The globe ident was modified in January 1972 to include a new BBC logo with rounded corners and an italic serif font for the 'Colour' legend. On 28 December 1974 the ident was reworked further, with yellow continents over a dark blue background and the term 'COLOUR' removed. The legend BBC1 was rendered in white, using a heavy weight of the Futura typeface. On 5 September 1981, the display was altered to green continents over a dark blue background with a double striped BBC1 legend in white.
The globe model in the machinery was altered over the years as it had to be frequently re-painted. This led to a number of odd variations: the tip of South Africa, the Cape Fold Mountains was pointed in some 1981 models and the Pacific islands more pronounced in others.
On November, 13, 2017 the "1981" globe was returned for BBC Children in Need "Rocks the Eighties".
A number of other presentational devices were used, the main one of these being the analogue clock. To allow enough light onto the model, a light was fixed onto the camera to shine onto the clock and other idents; this light was not used on the main ident however, which was internally lit; in any event, the mirrored background would have reflected the external light back at the camera and caused glare. The clock was mechanical, and featured numerals indicated by double lines that increased in thickness the further round the clockface. The clock also featured a 'polo' mint centre. The clock is quite distinctive, and became strongly associated with the BBC. The clock's colour and legend never differed from that of the main ident.
The mechanical clock was abandoned in December 1981 in favour of a computerised clock - except in Wales, which retained the mechanical clock until 1985, making it the last BBC1 mechanical clock. A rebranding happened the same year. It was the longest running clock of 1974 and 1985 in Wales and was the last region to adopt the computerised clock and preserved the polo dot. Following BBC2's rebrand to the electronic striped 2 ident, technicians started working on an electronic clock to accompany the new look, and following its completion it was this that replaced the mechanical version. The new clock featured a single uniform line thickness all the way round, except at 12, 3, 6 and 9 where the lines were doubled. The polo mint centre was also removed in favour of a central dot.
The looks were also accompanied by static programme captions. The captions for the 1969 to 1974 look used the legend of the ident at the bottom of the screen. They continued for a while after the new BBC1 logo was introduced. However, the style was changed in 1981 to feature a banner at the top of the image featuring double striped lines and the double striped BBC1 logo. This design was used until February 1985.

The mirrored globe was retired at 7 p.m. on 18 February 1985, with the first showing of the globe's replacement: the Computer Originated World or COW for short. The globe was retired because of the fact it was the only live mechanical model used on television and the maintenance required was making it difficult to use; even the 1981 rebrand caused a number of difficulties such as bad positioning, odd colours and other errors. The globe was also becoming old fashioned, due to its long service since the introduction of colour.
The Noddy system was abandoned with the globe, as all idents and clocks were now electronically generated, and as a result the equipment was not needed. Slide scanners were still used for the live origination of programme slides until the late 1980s, when the programme slides then became stored electronically.
The acronym NODD was first recorded in a web forum related to TV presentation, where an author unconnected with the BBC claimed it stood for Nexus Orthicon Display Device. However, the term is not recognised among the many surviving Presentation and Engineering staff who worked with the system and internal BBC paperwork of the era specifically refers to the camera system as "Noddy".
Presentation's "Noddy" camera also had a companion, originally named "Big Ears", which was a dual monochrome slide scanner, thus allowing in-vision changes between slides. With the advent of colour this was replaced with a Rank Cintel slide scanner, electronically similar to a flying spot telecine machine.
