A streaming content reproduction method establishes a connection with a provider via the Internet, and downloads and reproduces streaming content from the provider. A transmission bit rate of receive data is received from the Internet. A total amount of data of the streaming content and a playback bit rate thereof is obtained from a provider. A target amount of data to be buffered is calculated in advance based on a difference between the transmission bit rate and the playback bit rate and the total amount of data in order to reproduce the streaming data to its end without interruption. The streaming content downloaded from the provider is stored in a buffer. The streaming content is reproduced from the buffer after an amount of data of the streaming content stored in the buffer exceeds the target amount of data.
