Method and apparatus for decoding digital signal and apparatus for reproducing digital signal

摘要

A method and an apparatus for satisfactorily reproducing an image and voice even if skip reproduction is performed, the apparatus having a first decoding system for decoding coded data of each picture more forward than a skip start point, a second decoding system for decoding coded data of each picture following a skip end point and a switch which corresponds to skip reproduction so as to switch a data string decoded by the first decoding system to a data string decoded by the second decoding system. The second decoding system completes decoding of all of pictures required to decode pictures following the skip end point prior to completion of decoding pictures more forward than the skip start point by the first decoding system. When the first decoding system has decoded the pictures more forward than the skip start point, the second decoding system outputs decoded data of each picture following the skip end point. The switch switches an output from the first decoding system to an output from the second decoding system when the first decoding system has decoded pictures more forward than the skip start point.
