Abstract
In a moving picture managing device, a boundary sensor senses the boundary between a cut of the input moving picture consisting of a plurality of frames and another cut on the basis of the difference in the number of blocks at the time of encoding the moving picture for a frame between the frame and an adjacent frame. Based on the boundaries sensed at the boundary sensor, the moving picture is filed in cuts. The moving picture is processed so as to be stored in a memory in a tree structure fashion in which the moving picture is composed of scenes and a plurality of cuts, each scene consisting of cuts. The filing is managed in cuts under the tree structure.

A moving picture managing device comprising:
- input means for inputting a moving picture, said moving picture comprising a plurality of scenes, each scene comprising a plurality of cuts, each cut comprising a plurality of frames, and each frame comprising a plurality of blocks, each of said frames having a code associated therewith;
- means for detecting an amount of change in said moving picture by comparing information representative of differences between corresponding blocks in consecutive frames with a reference amount and for outputting a first determination signal when said amount of change is larger than said reference amount and a second determination signal when said amount of change is smaller than said reference amount;
- encoding means for encoding information representing a frame responsive to said first determination signal to produce first encoded information and for encoding information based on consecutive frames in said plurality of frames responsive to said second determination signal to produce second encoded information;
- means for determining boundaries between adjacent cuts in said plurality of cuts responsive to a sequence of said first and second determination signals;
- and
- storage means for storing said first and second encoded information and for storing said boundaries determined by said determining means.
A moving picture managing method comprising the steps of:
- inputting a moving picture, said moving picture comprising a plurality of scenes, each of said scenes comprising a plurality of cuts, each of said cuts comprising a plurality of frames, and each of said frames comprising a plurality of blocks and having a code associated therewith;
- determining information representative of differences between corresponding blocks in consecutive frames;
- comparing said information with a reference amount;
- outputting a first determination signal when said amount of change is larger than said reference amount and a second determination signal when said amount of change is smaller than said reference amount;
- encoding information representing a frame responsive to said first determination signal to produce first encoded information and information based on consecutive frames responsive to said second determination signal to produce second encoded information;
- locating boundaries between adjacent cuts in said plurality of cuts responsive to a sequence of said first and second determination signals;
- and
- storing said first and second encoded information and said boundaries detected in said determining step.
