Abstract
A system and method for synchronizing an audio signal and a video signal are provided. A decoding method in the system may include decoding an audio signal and a video signal received from an encoding apparatus, extracting first unique information of the audio signal from the decoded video signal, generating second unique information of the audio signal based on the decoded audio signal, determining a delay between the audio signal and the video signal by comparing the first unique information to the second unique information, and synchronizing the audio signal and the video signal based on the delay. The first unique information may be generated based on an audio signal that is not encoded by the encoding apparatus, and may be inserted into the video signal.
