Patent ID: 7023789

Claim:
A playback device, comprising: a drive for a storage medium; a scanning device for reading audio data recorded on the storage medium when the storage medium is inserted into the drive; a control device that checks whether the audio data read is compressed and that determines a type of compression of the audio data; a decompression device that performs a decompression of the audio data if the audio data is compressed; and a memory in which the control device stores the audio data of the storage medium read by the scanning device and detected as compressed, before the audio data is relayed to the decompression device; wherein audio data read is stored in differently addressed memory areas of the memory depending on a compression method used, whereby a first type of audio data read that is compressed according to a first compression method is stored in a first addressed memory area of the memory, a second type of audio data read that is compressed according to a second compression method is stored in a second addressed memory area of the memory, and wherein the decompression device is informed of a first association between the first addressed memory area and the first compression method and a second association between the second addressed memory area and the second compression method, and wherein the decompression device decompresses the audio data stored in the first addressed memory area by using a first decompression method associated with first addressed memory area, and wherein the decompression device decompresses the audio data stored in the second addressed memory area by using a second decompression method associated with the second addressed memory area.
