UK - Dual Color & B&W camera setup

[Penthode]

I recall the exchange of programming between the UK and Canada/US in the late 60s. ITV went colour in 1969 at the time of their switch to 625 in 1969.

Peter Cook an Dudley Moore reunited for the ITV series "Goodbye Again" in 1968. ITV was still black and white 405 lines and the dual camera setup I recall was to provide domestic 405 monochrome and US 525 colour.

I recall watching monochrome video conversion 625/405 to 525 in the 1960s. The CBC Canada and earliest PBS aired telecast of the BBC2 625 line black and white series the Forsythe Saga looked very much like optical conversion. The dynamic vertical resolution was horrible: I recall the credit roll and the end was virtually unreadable.

The introduction of the McMichael ACE, ITV DICE and BBC conversion equipment from 1969 onwards is well documented.
