The Genesis of Television Technological know-how (nineteen twenties-forties)
The Mechanical Era: Breaking New Ground
Complex Foundations
The 1st tv programs operated on astonishingly easy yet ingenious mechanical concepts. John Logie Baird's 1925 prototype utilized a Nipkow disk - a spinning disk with perforations organized in a spiral sample. This mechanical scanner converted illustrations or photos into electrical signals by way of a photoelectric cell, obtaining a resolution of 30 traces at 5 frames per second. When primitive, this breakthrough proved that tv was achievable.
