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