<P>PROBLEM TO BE SOLVED: To provide a performance clock generation device capable of accurately generating a performance clock matched with the progression of musical pieces and improving precision at each time when performing processing, and to provide a data reproducing device, a performance clock generation method, a data reproducing method, and a program. <P>SOLUTION: The data reproducing device performs time synchronization with original live videos, namely, can reproduce the videos synthesizing word images and the musical pieces matched with the progression of the musical pieces. The performance clock used when reading word data is allowed to correspond to a characteristic amount indicating reference data generated from history data indicating a past history and another characteristic amount indicating live musical piece data, so that the data reproducing device 1 can accurately generate the performance clock matched with the progression of the musical pieces. <P>COPYRIGHT: (C)2009,JPO&INPIT |
