Abstract

PURPOSE:To keep secrecy as to signal transmission and reception using a radio frequency by determining whether a luminance signal or color difference signal should be inverted in polarity on the basis of set information extracted from a video signal. CONSTITUTION:A composite video signal has a VIR signal extracted by VIR extraction part 65 and is stored in memory part 67. Then when keyword data supplied from a subscriber agree with the stored information, control data are supplied to respective polarity reproduction parts 62, 63 and 64 to reproduce a video signal.
