An apparatus, which controls a playback speed of a video content to enable the sound included therein to be in a well-audible range, is provided. A playback speed range is calculated based on sound characteristic information obtained by analyzing audio data of a video content and a predetermined sound parameter. A specific playback speed in the playback speed range is calculated based on a selected playback speed, and a video content is played back at the playback speed.
