Transatlantic TVIn 1928, John Logie Baird’s transmission of a TV image was received across the Atlantic ocean using short wave radio, from station 2 KZ at Purley, England to Hartsdale, NY. Though imperfect, an image showed the face of Mrs. Mia Howe. Baird's system was electromechanical: a light sensitive camera behind a rotating disc. The picture was crudely formed from a scan of thirty lines at twelve frames per second. The television receiver displayed a tiny, uneven image. This caused a sensation. The New York Times compared the event to Marconi’s sending of the letter “S” by radio across the Atlantic, 27 years earlier. |
