An automatic performance device includes a performance data receiving unit that receives performance data transmitted from a storage device without passing through a moving image distribution server, the storage device configured to store the performance data having a combination of performance information and time information, the time information indicating the time when the performance indicated by the performance information was carried out; a synchronization signal receiving unit that receives a synchronization signal by using an audio signal transmission path for an audio via the moving image distribution server; and a reproducing unit that reproduces the performance information of the performance data in synchronization with a video distributed at the time when the synchronization signal is distributed, at the timing corresponding to the time indicated by the time information and the time indicated by the synchronization signal.

Automatic performance device

A performance system includes a plurality of performance information output devices, a storage device, and a plurality of automatic performance devices. At least one performance information output device transmits performance data having the combination of an identifier, time information, and the performance information to at least one automatic performance device through the storage device without passing through a video distribution server. The at least one performance information output device transmits a synchronization signal to the at least one automatic performance device through the video distribution server. The at least one automatic performance device reproduces the performance information in synchronization with a video distributed at the time when the synchronization signal is distributed, at the timing corresponding to the time indicated by the time information and the time indicated by the synchronization signal.

Performance system

A plurality of musical instrument is connected to a server device through a network to form a storage system. The musical instrument generates performance data, and sends the performance data to the server device every time the performance data is generated. The server device receives the performance data sent from the musical instrument. The server device has a clock unit that measures date and time, and a storage unit that stores the performance data received by the receiving unit. Further, a file generation unit of the server device divides a polarity of the performance data stored in the storage unit into blocks based on the date and time of the performance data measured by the clock unit when the performance data is received by the receiving unit, and generates performance files corresponding to the blocks of the performance data.
