A device for producing a multimedia presentation consisting of content
includes a memory, a setting unit, an extraction unit, a requesting unit,
a receiving unit, and a combiner. The memory stores first digital media
classified by time of creation. The setting unit sets the duration of the
presentation and a time period for the content. The extraction unit
extracts from the memory portions of the first digital media created
during the time period. The requesting unit requests general digital
media corresponding to the time period from a general digital media
source. The receiving unit receives the general digital media from the
general digital media source. The combiner combines the received general
digital media with the extracted portions of the first digital media to
produce the presentation.
