Restoring Baird's image

This article discusses the early history of television and video recording following some fascinating discoveries. Those discoveries come from analysing and restoring gramophone videodisc recordings made between 1927 and 1935, 25 years before the first practical videotape recorder and nearly 50 years before the domestic videodisc player. The Nipkow disc, John Logie Baird's scanning and remote display of moving pictures and the early inventions in televison-phonovision and phonvisor-are discussed. The 30 line broadcast is also discussed.
