Abstract: The present invention relates to an apparatus and method for correcting synchronization errors, which involve correcting synchronization errors occurring between video signals and audio signals when multiple videos are combined. The apparatus and method of the present invention involve: storing synchronization errors between an initial video signal and an initial audio signal of each video to be combined when combining different pieces of video content; and combining multiple pieces of video content such that the initial synchronization error which is set to synchronize existing video signals with existing audio signals can be maintained when combining multiple pieces of video content. The apparatus and method of the present invention enable the drawbacks of conventional techniques, i.e. that video signals and audio signals are uniformly combined, errors are corrected, and thus the video signals and the audio signals are unsynchronized which results in unnatural video, to be overcome.
