摘要：
A managing method for a multimedia file includes the steps of: generating index information including a source identifier expressing a source having one or more of management units associated with the multimedia file as a title frame, positions of a leading frame and tail frame of the title frame in the source, and a position of a reference frame for decoding the leading frame; and recording the index information onto a recording medium, attaching the index information to the multimedia file. The managing method for a multimedia file may include the steps of: causing a user to specify one or more of the management units associated with the multimedia file as a title frame; generating index information in which a bit stream obtained by encoding a specified title frame is embedded, and recording the index information onto a recording medium, attaching the index information to the multimedia file.
