Abstract
A variable-speed communication and reproduction system consists of a server and a client device, and comprises a variable-speed data supplier for supplying a requested data set at a play speed specified by the user. The variable-speed data supplier includes the server. A control data communication system and a time-series data communication system are also included in the data supplier, which connect the server and the client. The communication and reproduction system further comprises a variable-speed reproducer for reproducing the data set supplied from the variable-speed data supplier at the specified play speed by adjusting the pitch of audio and the video frequencies, and a play speed setter responsive to the specified play speed for setting the specified play speed to the variable-speed data supplier and the variable-speed reproducer.
