Abstract
1342562 Composite picture reproduction GRUNDIG EMV 30 March 1972 [31 March 1971] 15091/72 Addition to 1286766 Heading H4F In a display arrangement for displaying marks 7, e.g. battle formations against a map &c. background 1, the map is hidden from TV camera 4 by means of two crossed polarized filters 5 and 6, and the operator draws his mark on the surface of the larger filter 5, which mark is thus viewed by the camera through one filter only and converted to video signals for transmission to the receiver station, possibly via (bandwidth reduction) store 17. A second copy 11 of the map 1 is viewed at the receiver station by a second camera 14 and the signals therefrom are combined with those received from camera 4 to produce a mark and map composite display 16 on monitor 15. Registration marks 18<SP>1</SP>, 19<SP>1</SP> and 18, 19 can be provided on filter 5 and map 11. The "mark" video signal may be intermittently applied to the monitor so that the mark is distinguished by flashing.
