 The UK IVC7000P subsequently became the pioneering forerunner of today's field production systems.The IVC7000P was used by LWT, Thames TV, Southern TV, ATV, Grampian TV, Harlech TV, and many of London's independent TV production companies in the 1970s.The R & D and support operations at IVC UK Ltd were particularly strong and went on to engineer many other products, and product variants, not least of which was the world's first Digital Audio transport for Decca records, and then the supply of IVC9000 transports for the world's first Digital Video recording project at the famous Independent Broadcasting Authority research centre in the UK at Crawley Court.
