Attempt to record mechanical television on gramophone records
This article is about the phonograph records visual signal format. For the experimental pay-television station, see Phonevision.
Phonovision was a patented concept to create pre-recorded mechanically scanned television recordings on gramophone records.[1] Attempts at developing Phonovision were undertaken in the late 1920s in London by its inventor, Scottish television pioneer John Logie Baird.[1] The objective was not simply to record video, but to record it synchronously, as Baird intended playback from an inexpensive playback device, which he called a 'Phonovisor'.[2][3] Baird stated that he had several records made of the sound of the vision signal but that the quality was poor.[4] Unlike Baird's other experiments (including stereoscopy, colour and infra-red night-vision), there is no evidence of him having demonstrated playback of pictures, though he did play back the sound of the vision signal to audiences.[5] Baird moved on leaving behind several discs in the hands of museums and favoured company members. Until 1982, this was the extent of knowledge regarding Phonovision.[6][7]
