Abstract

A plurality of I- or P-pictures for displaying video images with the same data as the last frame of the main data of the content are added as reproduction synchronization adjustment frames after the last frame of the main data; when reproduction leads a reference reproducing device, more synchronization adjustment frames are reproduced (ST); when reproduction lags, fewer synchronization adjustment frames are reproduced (ST). Reproduction can be synchronized among a plurality of reproducing devices () that read data from a storage medium and reproduce the data, or receive data by network delivery and reproduce the data, under conditions where system clock correction by use of PCR is impossible.
