Abstract
An optical medium, such as Blu-ray Disc (BD) medium, presents audiovisual information in a user selected Karaoke mode by mixing first and second audio streams and a textual stream according to synchronization information. For instance, the first stream has instrumentation and the second stream has vocals so that the audio output from the streams may include normal play mixing both streams to have instrumentation and vocals, instrumentation-only play having only one stream presented, or instrumentation with guide vocals having the stream associated with vocals processed at a subdued volume or varied speaker location. Alternatively, the first stream has instrumentation with vocals and the second stream has inverse vocals so that mixing the streams provides subdued or no vocals. The text stream presents lyrics in a text box of a graphics plane of a display, the lyrics synchronized to the instrumentation and vocals.
