Abstract:
1. A data reproduction device for expanding and reproducing compressed data downloaded through a communication network, comprising: memory means for temporarily storing the compressed data downloaded; data expanding means for expanding the compressed data stored in the memory means; reproducing means for performing streaming reproduction on data expanded by the data expanding means as soon as an amount of data stored in the memory means exceeds a first threshold value; detecting means for detecting a data size of the compressed data temporarily stored in the memory means and a compression rate of the compressed data downloaded; and control means for changing the first threshold value and a second threshold value for the data size of the compressed data stored in the memory means based on the compression rate detected by the detecting means, and reading the compressed data from the memory means when the data size of the compressed data temporarily stored in the memory means exceeds the first threshold value and transferring the compressed data to the data expanding means, said control means temporarily stopping reproduction when the compressed data is determined as being less than or equal to the first threshold value until the compressed data is determined as being greater than the first threshold value, said control means temporarily stopping downloading the compressed data from the network when the compressed data in the memory means exceeds the second threshold value until the compressed data is determined as being less than the second threshold value, the second threshold value being higher than the first threshold value.
