In order to define movement of a particular key to be automatically operated, first-order trajectory data are generated, on the basis of performance information, which are indicative of variation over time of position, velocity and acceleration components of the particular key. Jerk component related to the movement of the particular key is calculated on the basis of the acceleration component in the first-order trajectory data, and second-order trajectory data are generated by modifying the first-order trajectory data with the calculated jerk component. Then, a drive device for driving the particular key is servo-controlled on the basis of the second-order trajectory data. In this way, nonconstant acceleration (or constant jerk) control, rather than constant acceleration control, can be performed to control driving of the key during a successive key depression, so as to allow the successively-depressed key to operate with an increased smoothness.

An information processing apparatus includes a communication unit and a control unit. The communication unit is communicable with a plurality of client apparatuses over the same network that are capable of buffering and reproducing data transmitted from a server by progressive download. The control unit is capable of regularly obtaining buffer time information indicating a buffer time that expresses an amount of data buffered by the plurality of client apparatuses using a time necessary for reproduction of the data. Further, the control unit is capable of determining a client apparatus whose buffer time is minimum among the plurality of client apparatuses as a priority apparatus to which the data should be preferentially transmitted.

An electronic apparatus includes a reception section, a buffer section, a reproduction section, an operation reception section, a transmission section, and a control section. The reception section receives data of a content transmitted through streaming from a transmission apparatus. The buffer section buffers the received data. The reproduction section successively reads out and reproduces the buffered data. The operation reception section receives a pause operation and a resume operation regarding reproduction of the data. The transmission section transmits, in response to the pause operation and the resume operation, a pause request and a resume request regarding the reproduction to the transmission apparatus. The control section controls the buffer means to discard data overlapping data received after the resume request among the data buffered by the buffer means and buffer data identical to the discarded data, that is received after the resume request.
