A wireless communication device and a wireless communication method capable of curbing occurrence of latency even when performing wireless communication at predetermined time intervals are provided. MIDI data is transmitted and received by communication (B) performed through a wireless module during an intermission between communications (A) performed at predetermined time intervals through the wireless module. Accordingly, a communication speed for wireless communication is improved. Therefore, compared to a case in which wireless communication is performed by only the communication (A), MIDI data can be quickly transmitted and received, and thus occurrence of latency can be curbed.

A new interface is provided that supports simultaneous transmission of an audio signal and a MIDI signal. Signals consecutive in predetermined units are transmitted to a reception side via a predetermined transmission path. The signals consecutive in the predetermined units include a signal of a first predetermined unit of the predetermined units including an audio signal and a signal of a second predetermined unit of the predetermined units including a MIDI signal. For example, the audio signal is a linear PCM signal constituting a stereo 2-channel audio signal. For example, the MIDI signal includes packet data of a predetermined length, and the packet data of the predetermined length is divided into a plurality of pieces, and transmitted by being included in signals of a plurality of pieces of the second predetermined units.

A wireless communication device and a wireless communication method are provided. When a master mode is set in a mode memory, a mode setting notification is transmitted to a different wireless communication device. When a mode setting permission notification for the mode setting notification is received from the different wireless communication device, the master mode is settled as a communication mode, and the master mode is set in the mode memory. When a slave mode is set in the mode memory and when a mode setting notification is received from the different wireless communication device, the slave mode is settled as the communication mode, the slave mode is set in the mode memory, and a mode setting permission notification is transmitted to the different wireless communication device. Thus, the communication mode can be automatically set in a pair of wireless communication devices.

Providing real-time interaction between a first player and a second player to collaborate for a musical performance over a network, includes maintaining a reference data item generated using a musical instrument performed by a user; receiving first user input data generated using a first musical instrument, the received first user input data associated with the first musical instrument and the musical performance; receiving second user input data generated using a second musical instrument, the received second user input data associated with the second musical instrument and the musical performance; detecting a missing data packet within the received second user input data when generating real-time collaboration data for the musical performance; replacing the missing data packet using the reference data item to correct the second user input data; and generating real-time collaboration data for the musical performance based on the corrected second user input data.

A musical-performance-information transmission method using a first instrument and a second instrument, wherein the first instrument produces sounds in accordance with a user's musical performance and generates musical-performance data in accordance with the produced sounds and the second instrument produces sounds by receiving the musical performance data via a communication means. In the musical-performance-information transmission method, a mixed-sound signal is generated in accordance with a mixture of sounds produced by the first instrument and sounds that are different from the sounds produced by the first instrument, a reference signal is generated in accordance with the sounds produced by the first instrument, and on the basis of the mixed-sound signal and the reference signal, the reference signal is removed from the mixed-sound signal, generating a separated signal, and sound is emitted on the basis of said separated signal.

A method of generating a stream comprising synchronized interactive content is described. The method comprises the steps of: transmitting a first stream from a studio to a terminal or a terminal system of a first user and to a buffer; transmitting in response to the first stream a second stream to a mixer connected to the buffer, the second stream comprising content generated in reaction to the content of the first stream; providing the mixer with a temporal relation between the packets in the first and second stream; generating a first output stream comprising a substantially synchronized content by mixing packets in second stream with packets of the buffered first stream on the basis of the temporal relation.
