Abstract:
1. A video and audio reproduction apparatus comprising: an isolation module configured to isolate a video signal and an audio signal from a content; a video demodulator configured to demodulate the video signal isolated by the isolation module; an audio demodulator configured to demodulate the audio signal isolated by the isolation module; a video playback speed setting module configured to set a video playback speed at which to reproduce the video signal by gradually decreasing from a high playback speed higher than a normal playback speed to the normal playback speed, in a time between a specific time that precedes, on the time axis, a start time of playback of a scene with the video signal at the normal playback speed and the start time of the playback of the scene at the normal playback speed, the video playback speed being measured by a number of blocks reproduced per unit time; an audio playback speed setting module configured to set an audio playback speed at which to reproduce the audio signal higher than a normal playback speed to the normal playback speed, in a time between a specific time that precedes a start time of the playback of the scene with the audio signal at the normal playback speed, on the time axis, to the start time of the playback of the scene at the normal playback speed, the audio playback speed being measured by a number of blocks reproduced per unit time, and the audio playback speed is controlled when the scene starts, in order to synchronize the audio playback speed with the video playback speed, the audio playback speed setting module also gradually decreasing the number of blocks reproduced per unit time, or the high playback speed, at a specific time that precedes, on the time axis, the playback of the scene at the normal playback speed, thereby decreasing audio in volume during the high speed playback, and gradually increasing the audio in volume when the audio playback speed drops to a prescribed value; and a signal processor configured to process the video signal at the video playback speed set by the video playback speed setting module and demodulated by the video demodulator and the audio signal at the audio playback speed set by the audio playback speed setting module and demodulated by the audio demodulator, such that the video signal and the audio signal are made reproducible the video and audio reproduction apparatus.
