Abstract:
1. A data reproducing system comprising: a server device that streams and outputs streaming data to a network; and a plurality of audio reproducing devices, each comprising: a receiver that receives the streaming data via the network; a buffering device that buffers the received data; a clock frequency generator that generates a clock frequency; a reproducing unit that reproduces the data by reading the data from the buffering device according to the generated clock frequency; and a controller that controls a reproducing speed of the reproducing unit by controlling the clock frequency generator to change the clock frequency in response to excess and deficiency of an amount of buffer from a predetermined target value to maintain the amount of buffer of the buffering device at the target value, wherein the respective receivers of the plurality of audio reproducing devices receive the same audio data from the server system, and wherein the respective controllers of the plurality of audio reproducing devices control the reproducing speeds of the respective reproducing units using the same target value to maintain the amount of buffer of the respective buffering devices.
