Abstract
In a VCR having an automatic time setting function, a receiving circuit receives a current time signal from a broadcasting station, and a wave-shaping circuit converts the current time signal from the receiving circuit to a digital signal. A decoder decodes the digital current time data from the wave-shaping circuit, and a memory stores the decoded current time data from the decoder in frame units. A frame detector detects a starting point of each frame of the current time data from the wave-shaping circuit and resets the current time data of a frame previously stored in the memory upon detecting the starting point. A tuner tunes audio and video signals from the broadcasting station to a reference frequency, and a control unit controls the operation of the VCR and converts the current time data to the current time. An on-screen display unit superimposes a timer signal or the current time on the video signal under the control of the control unit and outputs the resultant signal to an external display unit. A character display unit displays the current time from the control unit, and a key matrix unit applies either a summer time display function signal or a time siren function signal to the control unit according to a user's selection.
