Abstract

A video/audio synchronization apparatus includes: a decoder configured to decode a frame contained in encoded video data and determine playback time of the frame based on a first clock signal, and decode encoded audio data and determine playback time of an associated audio signal contained in the decoded audio data and to be played back simultaneously with the frame, based on a second clock signal different from the first clock signal; a silent period detector configured to detect a silent period from within the associated audio signal; and an audio timing adjuster configured to reduce a difference between the playback time of the frame and the playback time of the associated audio signal by skipping or repeating a silent period contained within a period of the associated audio signal.
