Abstract

437,339. Television. BAIRD, J. L., and BAIRD TELEVISION, Ltd., 58, Victoria Street, Westminster. May 15, 1935, No. 18142. Divided out of 431,339. [Class 40 (iii)] An interleaved scanning is produced by deflecting a cathode ray with a regular periodicity image frequency a, and an irregular periodicity line frequency b. If n sets of interleaved lines are required, the period of the last line cycle of each of the first (n-1) sets is increased by 1 of the time of a normal line n cycle, and the period of the last line cycle of the nth set is decreased by n-1/n of the time of a normal line cycle. Specifications 381,898 and 431,339 are referred to.
