PROBLEM TO BE SOLVED: To prevent wrong or inaccurate synchronous reproduction operations due to delay of data transmitted to a stream data transmitting devices when synchronously reproducing a plurality of received stream data. SOLUTION: Data reproduction clients 14a and 14b in a data receiving device 14 send, under control of a reproduction controller 14c, data transmission request signals for sending stream data 11a and 12a respectably to data transmitting devices 11 and 12. On receiving the data transmission request signals, the data transmitting devices 11 and 12 notify a data transmission control device 13 of reception of signals. After receiving all notifications, the data transmission control device 13 sends control signals to the data transmitting devices 11 and 12 to start transmission of stream data 11a and 12a. In accordance with the control signals, the data transmitting devices 11 and 12 send the stream data 11a and 12a sequentially to the data reproduction clients 14a and 14b, which receive the data and sequentially execute reproduction-output processes. |
