Abstract: A method of displaying time of a VCR including steps for checking whether current time data is received, determining states of the received current time data corresponding to a duty cycle at times when the current time data is received and converting the determined logic states of the current time data to current time. The current time is then displayed, The current time is superimposed on a video signal and a resultant superimposed signal is displayed. The resultant superimposed signal is recorded when the user requires recording of the current time together with the video signal.

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.
