Abstract
According to one of embodiments, a method and apparatus for reproducing video and audio changes a playback speed for video and a playback speed for audio independently of each other. To provide an apparatus and method for controlling the playback speeds shortly before a period in which the video and audio should better be played back at a normal-speed, thereby to reduce the strange feeling the user may have as the playback changes from the high-speed playback to the normal-speed playback, a video signal and an audio signal are first isolated from a content and then demodulated. A playback speed is set for the video signal modulated, and a playback speed is set for the audio signal modulated. The video signal and the audio signal, each set to a playback speed, are output.
