Title: Television system
Inventor: MILBURN JOHN RICHARD
IPC: H04N7/18
Filed: 1959-03-18
Abstract: 893,918. Television. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 16, 1960 [March 18, 1959], No. 9444/59. Drawings to Specification. Class 40(3). In a television system the definition in the centre of interest (e.g. in the centre of the picture) is increased by employing non-linear scanning waveforms for the pick-up and the display devices. The waveforms may be produced by superimposing on the normal sawtooth deflection waveforms sinusoidal waveforms of the same frequency, the effect of such non-linear scanning being to reduce the spacing of the lines in the central portion of the picture and to reduce the velocity of line scanning in the same portion. Other non-linear waveform shapes may be employed if desired. The invention may be applied to a closed-loop television system in which the pick-up device is mounted on the telescope (provided with crossed reference wires) of an auto-follow radar apparatus and the display device situated at a remote stationary position. In this case the raster lines are arranged to be parallel to one of the reference wires. By varying the relative phase of the superimposed sinusoidal waveform and the sawtooth wave the position of the centre of interest may be varied.
