Video Recording
In the early days, film was the only medium available for recording television programmes. Thoughts turned to magnetic tape, which was already being used for sound, but the greater quantity of information carried by the television signal demanded new studies. During the 1950s, a number of American companies began investigating the problem.
Television Cameras
In the 1920s, American engineer, Philo Taylor Farnsworth devised the television camera, an image dissector, which converted the image captured into an electrical signal.
Television Cameras
The pick-up tube is the main element governing the technical quality of the picture obtained by the camera. The first electronic cameras using iconoscope tubes were characterised by very large lenses, necessary to ensure enough light reached the pick-up tube.
Video Stills - Digital Photography
The still video or digital camera (the Sony Mavica single-lens reflex) was first demonstrated in 1981. It used a fast-rotating magnetic disc, two inches in diameter, recording on it up to 50 images formed in a solid-state device in the camera. The images were played back through a television receiver or monitor, or printed out.
Tape Recording Technology - Audio and video magnetic recording has had greater impact on broadcasting than any other single development since the invention of radio/TV transmission itself.
