Abstract
In a moving picture managing device, representative pictures are selected beforehand from the individual cuts or scenes of a moving picture in which a scene and cuts are arranged in a tree structure, and then are stored in a magnetic disk as decoded high-speed displaying pictures. Upon request of high-speed display, those representative pictures are browsed sequentially and displayed.

A moving picture managing device comprising:
- input means for inputting information according to a moving picture which has a format formed by a plurality of blocks;
- sensing means for, based on the difference between the number of blocks in encoding the moving picture within a frame and the number of blocks in an adjacent frame, sensing a boundary between a cut of the input moving picture and another cut, each cut consisting of a plurality of frames;
- storing means for storing moving picture information corresponding to said moving picture supplied in units of one cut according to the boundary sensed by said sensing means, and high-speed displaying pictures obtained in such a manner that a particular frame is selected as a representative picture from the frames constituting a cut, each selected frame representing at least each of said cuts;
- output means connected to said storing means for outputting in units of one cut the decoded moving picture read from said storing means;
- first specifying means for specifying a partition between a scene and another scene, each scene consisting of a plurality of cuts of the output moving picture from said output means;
- first processing means for, based on the specification by said first specifying means, causing said storing means to store a moving picture arranged in a tree structure of a plurality of scenes and cuts, each scene being coupled to a plurality of cuts belonging to the lower plane;
- second specifying means for specifying the browsing and output of said high-speed displaying pictures stored in said storing means;
- and
- means for, based on the specification by said second specifying means, causing said output means to perform the output of the high-speed displaying pictures browsed from said storing means.

A method of managing a moving picture comprising steps of:
- inputting information according to a moving picture which has a format formed by a plurality of blocks;
- based on the difference between the number of blocks in encoding the moving picture within a frame and the number of blocks in an adjacent frame, sensing a boundary between a cut of the input moving picture and another cut, each cut consisting of a plurality of frames;
- storing encoded moving picture information corresponding to said moving picture supplied in units of one cut according to the boundaries sensed at said sensing step, and the decoded high-speed displaying pictures obtained in such a manner that a particular frame is selected as a representative picture from the frames constituting a cut, each selected frame representing at least each of said cuts in a storing means;
- outputting in units of one cut the decoded moving picture read by said storing step;
- first specifying a partition between a scene and another scene, each scene consisting of a plurality of cuts of the output moving picture;
- based on the specification by said first specifying step, storing a moving picture arranged in a tree structure of a plurality of scenes and cuts, each scene being coupled to a plurality of cuts belonging to the lower plane;
- second specifying the browsing and output of said high-speed displaying pictures stored in said storing means;
- and
- based on the specification by said second specifying step, performing the output of the high-speed displaying pictures browsed from said storing means.
