ABSTRACT:
At the time of stopping the first reproduction process, a main controller makes a RAM store audio identification information corresponding to the kind of audio having been reproduced in the preceding reproduction process. At the time of restarting reproduction process, the main controller so controls a demultiplexer as to extract, from the compressed audio data read out by the optical pickup, compressed audio data having the same audio identification information that the RAM stores. Subsequently, the main controller so controls the demultiplexer as to send the extracted compressed audio data to the audio decoder.Thus, in a DVD player which is absent of a DTS audio reproduction function or output function, compressed data of DTS audio can be prevented from being sent to an audio decoder, thereby the DVD player can be prevented from becoming unable to output audio.
