Title:
MOVING IMAGE ENCODING SYSTEM FOR REAL-TIME REVERSE REPRODUCTION
Document Type and Number:
Japanese Patent JP3663559
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a moving image encoding system for real-time reverse reproduction for generating a bit stream for reverse reproduction in real time concerning a moving image encoding system.
SOLUTION: Concerning an image encoder 20 for generating the bit stream for forward reproduction by performing intra-frame encoding and inter-frame predictive encoding under the limitation of a closed group-of-pictures(GOP), in the preceding step of this image encoder 20, a reverse frame rearranger 12 is provided for reversely exchanging input frames for each GOP while storing the frames more than the GOP showing the number of frames in I image encoding cycles and in the following step of the image encoder 20, a bit stream rearranger 13 is provided for successively piling up and storing these bit stream outputs in a memory while returning them for each OP. The contents in this memory are successively reproduced retroactively from the latest GOP, the bit stream for reverse reproduction is outputted in real time.
