Abstract: A playback device of the present disclosure includes a processing unit and a control unit. When having acquired identification information, the control unit calculates, on a playback time axis and based on the acquired identification information, a first point-of-time on the playback time axis, the first point-of-time being a point-of-time turning back a current point-of-time on the playback time axis by a first duration-of-time satisfying a first predetermined condition, and newly sets the calculated first point-of-time in the processing unit. The processing unit generates a video in which frames from the first point-of-time are arranged in chronological order, based on at least a part of acquired 6DoF content, a position and an orientation of a set viewpoint, and the first point-of-time newly set by the control unit.
