Abstract: A CC data detecting/inserting unit 11 detects the presence or absence of the CC data superimposed on an input video signal, and a control unit 14 decides the contents of the operation command by a remote control signal. Where the start of recording or release of pause of the recording is instructed, a CC data insertion controlling unit 12 produces a control signal so that a control code indicative of “clear” is read out from a CC data storage memory 13.
