<p>The present invention carries out automatic performances in synchronization with distributed video at a plurality of automatic performance devices while suppressing the influence of the state of the communication path passing through a moving image distribution server. Mutually different instrument IDs are allocated to automatic performance pianos (30a, 30b) which are any one of music IDs of instrument terminals which are connected via a network. The automatic performance pianos (30a, 30b) receive performance data having the combination of performance information and date and time information indicating the date and time when the performance which the performance information denotes is carried out, from a server device (20) without passing through a moving image distribution server (40). The automatic performance pianos (30a, 30b) receive a synchronization signal from the moving image distribution server (40) and reproduce the performance information which is synchronized with the distributed video at the time when the synchronization signal is distributed, on the basis of the received performance data, at a timing corresponding to the date and time indicated by the the performance data including the instrument ID which is shared with the device itsself and the date and time indicated by the synchronization signal.</p> |
