Abstract
An apparatus for reproducing a digitally encoded signal from a disk medium, comprises a source of a bitstream representative of the digitally encoded signal. A processor is coupled to the bitstream for processing the bitstream to extract at least a first and a second data type represented therein. A memory is controllably coupled to the processor for storing one of the first and a second data types. A controller is coupled to control allocation of the memory, wherein a first reproducing mode the controller allocates the memory for storing the first data type, and in a second reproducing mode the controller allocates the memory for storing the second data type.
