摘要

A method of the present invention for reproducing a media data set includes a recording step (S 12) of recording a part of the media data set as a data set to be complemented; an instruction receiving step (S20 and S21) of receiving an instruction inputted by a user; a receiving step (S23) of receiving a complementing data set from an external device via a network in accordance with a media data set reproduction instruction being received, the complementing data set being for complementing the data set to be complemented; and a combining and reproducing step (S24) of (I) combining (a) the data set to be complemented, which is recorded in the recording step and (b) the complementing data set received in the receiving step, so as to obtain a compressed media data set, (II) decompressing the compressed media data set through a reversed process of a compression process so as to obtain a reproducible media data set, and (III) reproducing the reproducible media data set. <IMAGE>
