ABSTRACT:
An image signal recording and reproducing system of this invention includes an apparatus for reproducing an image signal from a recording medium on which the image signal is recorded in a recording format selected between a first recording format for recording a reference signal for time base correction together with the image signal and a second recording format for recording the image signal without the reference signal for time base correction. The apparatus is arranged to detect whether or not the reference signal for time base correction is present in a signal reproduced from the recording medium and then to process and reproduce the signal reproduced from the recording medium on the basis of a reproduction format selected between a first reproduction format corresponding to the first recording format and a second reproduction format corresponding to the second recording format in accordance with the detection result. Accordingly, it is possible to reproduce the image signal in a correct format corresponding to the recording format of the image signal.
