Patent Images
1. An audio/video reproducing apparatus comprising:
- an audio data storage unit storing audio data;
an ancillary data storage unit storing ancillary data;
a decoder decoding the audio data and outputting decoded audio data and an audio synchronization signal;
a processor extracting at least a portion of said ancillary data corresponding to the audio synchronization signal from the ancillary data storage unit in response to an ancillary data request signal;
a synchronization and ancillary data output unit analyzing the extracted ancillary data and outputting display data in synchronization with the audio synchronization signal; and
a video controller extracting, from the display data, text data corresponding to pronounced audio data, which is displayed on a display when the decoded audio data is pronounced by an audio device.

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.
