摘要：
A demultiplexing apparatus includes a data obtainment unit to obtain the MP4 file data, and a decoding unit to demultiplex the MP4 file data obtained by the data obtainment unit into pairs of a moov and a mdat and pairs of a moof and a mdat, and decode those pairs pair-by-pair. A content duration specification unit specifies the content total duration based on the content total duration information contained in the moov of the MP4 file data obtained by the data obtainment unit and a playback unit displays the content total duration specified by the content duration specification unit.
