Abstract
A data synchronized playback apparatus comprises a buffer which stores streaming data, a buffer fill quantity measurement unit which measures the amount of streaming data stored in the buffer, a decoder which decodes the streaming data and sends decoded data to a D/A converter, a D/A converter which converts the decoded data to an analog signal, a clock generator which generates a clock signal with a frequency that changes according to the measured data quantity, and the digital/analog converter operates based on the clock signal generated by the clock generator.
