Abstract: An apparatus and method for reproducing ancillary data in synchronization with audio data. An audio/video reproducing apparatus may receive audio data and ancillary data from separate data sources, and synchronize the ancillary data with the audio data. The synchronization may enable, for example, music lyrics and/or subtitles of movies to be displayed to a user. The displayed data may provide reproduced audio data with corresponding images or text for each sentence of text data displayed. Additionally, currently pronounced text data and other displayed text data may be displayed in different color.
