Recorded Pictures.

Public Demonstration of Latest Invention. LONDON, May 21. NEW scientific wonder, which promises to be one of the great home entertainments of the future, was demonstrated in public for the first time this week. The inventor, Mr F. Plew, demonstrated “ gramovision,” or “ recorded television,” at Selfridge's before a number of Press representatives. He put a record on a gramophone turntable and pictures appeared on the screen of a television receiver. Any one with a set that receives 30-line television can put one of these discs on a gramophone turntable and, by means of a suitable pick-up connected to the receiver, see this “ recorded television.” Ten Years’ Work. Suitable records can be made for the television sets that will receive the high-defini-tion programmes to be sent out by the 8.8. C. in the near future. “ I have been working for about ten years on television and for two years on this idea,” Mr Plew said. “ Next week I shall demonstrate a record containing both vision and sound. “ The addition of sound is a fairly simple matter.” Television pictures, he explained, are converted into mechanical vibrations which can be recorded on a disc. When these are played back to a television set by means of a pickup the set reconverts the mechanical vibrations into electrical vibrations—and then into television pictures.
