Patent number: 6477181Abstract: In transmitting a plurality of data arranged in a time series of a first period (T), there is formed, every predetermined second period (SF) longer than the first period (T), a packet containing a plural number (x) of data supplied within a given cycle of the second period (SF). At that time, one data is specified from among every group consisting of a fixed number (M), not smaller than two, of the data, and time information indicative of a time position of the specified data is attached to the packet which the data belong to. A receiving-end unit reproduces the data, by reproducing the respective time positions, i.e., the first period (T), of the individual data on the basis of the time information contained in the received packet.Type: GrantFiled: November 5, 1998Date of Patent: November 5, 2002Assignee: Yamaha CorporationInventors: Junichi Fujimori, Yoshihiro Inagaki, Hirotaka Kuribayashi, Yasushi Ohtani, Tatsutoshi Abe

Patent number: 5652400Abstract: A musical network system has a plurality of musical equipments interconnected to each other through a communication network which circulates a control message for producing a musical sound. One musical equipment has a transmitter for transmitting a control message to the communication network. Another musical equipment has a receiver for receiving the control message from the communication network. An internal tone generator operates according to the received control message for producing a musical sound. A detector detects whether the received control message is a right one which may not disturb operation of the generator means or a wrong one which may disturb operation of the generator means. A transmitter returns an error message to the one musical equipment through the communication network when the detector detects that the received control message is the wrong one.Type: GrantFiled: August 7, 1995Date of Patent: July 29, 1997Assignee: Yamaha CorporationInventors: Junichi Fujimori, Tatsutoshi Abe
