Abstract

An apparatus for reproducing a digitally encoded signal from a disk medium, comprises a transducerwhich transduces the digitally encoded signal. A memory is coupled to the transducer for storing the digitally encoded signal. A decoder is responsive to the digitally encoded signal for decoding a picture therefrom. A controller for the memory, wherein a first operational mode the controller controls the memory to read the stored digitally encoded signal from the memory responsive to a first sequence and in a second operational mode the controller controls the memory to read the stored digitally encoded signal from the memory in a second sequence.
