An audio/video device, which controls the synchronization of analog video and audio signals using time information, and a method of controlling the synchronization are provided. The audio/video device comprises a reference clock generation unit that generates and outputs a reference clock having a predetermined period of time. A signal processing unit records the time information corresponding to the reference clock onto a predetermined region of the digital video data and digital audio data in order of receiving the digital video data and digital audio data which have been decoded, and performs various signal processes to output a signal processed video signal and audio signal. A memory stores the digital video data and digital audio data recorded with the time information. Accordingly, the same time information is recorded for the video data and its corresponding audio data, so that the synchronization of the analog video signal and audio signal are controlled exactly.
