Abstract:
1. A computer-implemented method of describing a multiple level digest segment information scheme for multimedia contents in order to provide multiple levels of digest streams for each multimedia content, the method comprising: describing level information of digest segments using multiple levels in a content-based data area of a multimedia stream; describing the level information and time range information of each digest segment in a digest segment information structure; and describing a digest segment information scheme with a set of digest segment information structures, wherein a digest level running time information or a digest stream running time information is added to the digest segment information scheme, wherein the digest level running time information is information about a sum of running time of digest segment information structures of the same digest level described according to digest levels, and the running time information of the digest stream is a running time information of a possible digest stream.
