Abstract
A circuit for detecting the recording/playback mode of a system, e.g., a video tape recorder (VTR), for recording/playing back an image signal on/from a recording medium, using first and second input signals derived from pilot signals also recorded on the recording medium. The circuit includes a first peak value detector for detecting the peak value of the first input signal, and for generating a first output signal representative of the peak value of the first input signal, and a second peak value detector for detecting the peak value of the second input signal, and for generating a second output signal representative of the peak value of the second input signal. The circuit further includes a comparator for comparing the first output signal and the second output signal, and for generating a comparison output signal representative of the difference therebetween and, a mode discrimination signal generating circuit, responsive to the comparison output signal, for generating a mode discrimination signal indicative of the recording mode that the image signal was recorded in, and the playback mode that the image signal is being played back in.
