摘要

PPROBLEM TO BE SOLVED: To smoothly synchronize two kinds of audiovisual information being either voice information with periodicity or image information with periodicity during reproduction. PSOLUTION: The synchronous reproducing method for synchronizing two kinds of audiovisual information during reproduction includes at least: a step S4 for multiplying a periodic accent number BPMSBM/SBper unit time of one kind of audiovisual information by a plurality of numerical values forming a monotone increasing sequence in a multiplication part; a step S5 for selecting a numerical value bSBopt/SBthe most approximate to a periodic accent number BPMSBO/SBper unit time of the other kind of audiovisual information from the numerical value group obtained by the multiplication in a selection part; and a step S6 for outputting an optimum adjustment factor fSBopt/SBobtained by dividing the periodic accent number BPMSBO/SBper unit time of the other kind of audiovisual information by the bSBopt/SBin a division part.
