In a video device having a reservation recording function for reserve recording of a television broadcast signal, a channel inputted via the D / A converter 16 while storing a frequency equal to the time signal frequency according to a time signal of multiple channels as a reference time signal. The reference signal frequency generator 17 which generates a reference signal frequency in accordance with the information, and the tuner 13 is tuned to the audio signal processing through the audio signal processor 14 and digitally converted through the A / D converter 15 A reservation from the function comparison input unit 10 and the frequency comparison unit 18 for comparing the time signal frequency of the time signal of the predetermined predetermined channel with the reference time signal frequency from the reference time signal generator 17 The microcomputer 19 further comprises a microcomputer 19 for outputting a control signal for setting the clock time of the timer 12 when the mode input signal is inputted by the setting of the conversation operation. Outputting a control signal for switching a predetermined channel to the tuner 13 at a predetermined time before a regular news broadcasting time, and outputting a control signal according to a predetermined channel tuned to the reference time signal frequency generator 17, and then If the time signal according to the time news of the predetermined channel to be compared in the frequency comparison unit 17 and the existing time signal frequency from the sound standard time frequency generator 17 is controlled so that the time of the timer 12 is set to time It is characterized in that the operation.
