A data reproducing system includes: a receiver that receives streaming data via a network; a buffering device that buffers the received data; a reproducing unit that reproduces the data by reading the data from the buffering device; and a controller that controls a reproducing speed of the reproducing unit 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.

A distribution unitdivides PCM audio data in plurality of divided data. Each divided data has overlapping sections overlapping with previous and following divided data. An MP3 encoding unitencodes each divided data individually into MP3 data. A filtering process at the time of encoding is executed by using the overlapping sections as similar to before the division of the data. An analyzing unitanalyzes the overlapping sections of each divided data encoded into the MP3 data and searches a frame where main data (bit storage values) are not overlapping. A combiner unitcombines the adjoining divided data at the searched frames as combining frames. Although the audio data is divided and the divided data are encoded to MP3 data by parallel processes, a continuity of the data and compressing quality can be maintained.
