A playback device and the like that can perform repeated playback without lowering video quality to perform the repeated playback while synchronizing audio data with video data, includes a unit 71 that specifies an IN point as a start position and an OUT point as an end position of repeated playback on a temporal axis of audio data, a unit 81 that registers each of the specified points, a unit 82 that decides a video frame corresponding to an address of the specified IN point as an IN point frame and a video frame corresponding to an address of the specified OUT point as an OUT point frame, and a unit 83 that limits a video frame to be output to a playback segment of the repeated playback to a video frame positioned between the IN point frame and the OUT point frame on a temporal axis of video data.
