Abstract
A playback apparatus including: a Clip information read circuit 5 that reads supplementary information from a recording medium 1, which also includes a video signal, and judges based on the supplementary information whether the video signal is of a first frame frequency or of a second frame frequency; a mode setting unit 13 that sets either a continuation or non-continuation mode, the continuation mode prohibiting and the non-continuation mode allowing a switch between frame frequencies during a playback; and a 24 Hz-60 Hz conversion circuit 7 and a digital modulation circuit 9 that, if the continuation mode is set, output the obtained video signal if it is of the first frame frequency, and generate a video signal of the first frame frequency by converting the obtained video signal and output the generated video signal if the obtained video signal is of the second frame frequency.
