Abstract:
1. A playback device that performs video output to a display device by converting an output frame rate of source video signals in accordance with an operation mode of the playback device, the source video signals having a first period in which a frame rate is a first frame rate and a second period in which the frame rate is a second frame rate, the playback device comprising: a mode setup unit operable to, in accordance with a user selection, set the operation mode to one of a fixed mode in which the output frame rate is fixed to the first frame rate and a switchable mode in which the output frame rate is switchable between the first frame rate and the second frame rate; a switch unit operable to switch a video output mode between (a) a first output mode in which the source video signals are output in the first period without converting the output frame rate, and are output in the second period by converting the output frame rate to the first frame rate and (b) a second output mode in which the source video signals are output in the second period without converting the output frame rate, and are output in the first period by converting the output frame rate to the second frame rate; and a switch reception unit operable to, while the source video signals are output to the display device in the switchable mode, receive a user instruction to switch the output frame rate from one of the first frame rate and the second frame rate to the other, wherein if the switch reception unit receives the instruction to switch the output frame rate to the second frame rate, the switch unit switches the video output mode to the second output mode, and if the switch reception unit receives the instruction to switch the output frame rate to the first frame rate, the switch unit switches the video output mode to the first output mode.
