Abstract:
1. A Compressed image data reproducing apparatus, comprising: a storage device for memorizing as control data a structure of a data file in which an interval including an intra-coded frame and an inter-coded frame composed using a forward direction prediction from said intra-coded frame or an inter-coded frame at the past time, in a group of pictures (GOP) is variable; a system control circuit for executing motion compensation using a time correlation at the time when image data compressed and coded by variable length codes are reproduced, wherein: a picture search is executed by using said control data; further comprising: a first decoder which obtains compressed image data through a bus and decodes obtained compressed image data and outputs decoded data as first reproduced image data; a second decoder which obtains compressed image data through said bus and decodes obtained compressed image data and outputs decoded data as second reproduced image data; and a selector which outputs reproduced image data by changing over said first reproduced image data and said second reproduced image data in frame unit time, wherein non-linear editing reproduction is executed by using said reproduced image data outputted from said selector.
