In the last lecture of his CHRISTMAS LECTURES series, Geoffrey Gouriet shows us some of the most remarkable inventions that back in 1972 were still under development.
We learn about the "Viewphone", a device which not only transmits sound but also video, and how optic fibres would be bringing such technologies into our home. Also, we are presented with a laser disc, straight from the research lab, that can store video; a huge breakthrough at the time that took 45 years to achieve.
Among other great demonstrations, Gouriet sets up a live broadcast from within the lecture theatre as well as transmiting a colour television signal through an optic fibre and have it broadcasted; as Gouriet said: "A world first!".
