Title: Improvements in or relating to television standards conversion apparatus
Inventor: DAVIES ERIC
IPC: H04N7/01
Filed: 1960-09-05
Abstract: 903,796. Television. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. May 19, 1961 [Sept. 5, 1960], No. 30604/60. Class 40 (3). In a television scanning standards conversion system in which pictures according to a first set of scanning standards, together with a peak white reference stripe RS (Fig. 2) occurring during the " back-porch " BP (Fig. 3) of the line blanking period BLP are reproduced by a picture tube 1 (Fig. 1) and "viewed" by a camera tube 9 operating according to a second set of scanning standards, the level of the out put signals from tube 9 being varied by controlling the gain of amplifier 18 in accordance with variations in the signals from the reference stripe to compensate for flicker caused by the different scanning standards, the distance between the reference stripe RS and the picture master is increased by increasing the scanning velocity in the line direction during the " backporch " interval following the stripe to ensure that the output signal from camera 9 during the scanning of the reference stripe is dependent solely on the brilliance of the latter and not affected by the light and shade of the edge of the actual picture. The required increase in scanning speed is produced by supplying to the line-scanning generator 3 a suitably phased pulse derived from the generator 8 which produces the reference stripe under the control of the line synchronizing source 5 and a similar speed increase is produced in the line scanning rate employed by the camera tube.
