Abstract
A data reproduction device is provided for achieving seamless reproduction of a stream where a validity of a bandwidth extension function is switched in the stream. The data reproduction device includes an input frequency obtainment unit analyzing header information Hdr and obtaining an input frequency FSin, which is the frequency of basic data, an output frequency determination unit performing predetermined processing based on the input frequency FSin and determining an output frequency FSout, which is the sampling frequency of a decoded frame Fdata, and a decoding unit () which, if the SBR function is valid in a frame to be decoded, decodes sample data at the input frequency FSin and extends the bandwidth of the sampling frequency up to the output frequency FSout, while if the SBR function is not valid in the frame, upsamples the decoding result obtained at the input frequency FSin to the output frequency FSout.
