Abstract:
1. A system for playing a digest of a moving image file, comprising: a header parsing part that parses a header of the moving image file and acquires information concerning the playback length M and random access point of the moving image file; a section dividing part that divides the playback length M by the number N of equal sections and determines a starting point S(i) of each of the sections; a correction part that corrects the starting point S(i) to a closest random access point R(i) of the moving image file; and a digest playback part that determines a playback segment P(i) of each of the sections which corresponds to a distance extended from the closest random access point R(i) by a playback length L, and sequentially plays the playback segments P(i).
