Abstract

A playback device for playing back a playlist by determining, as a current sub-playitem, a sub-playitem that is optimum for the current sub-playitem each time a current playitem changes. The playback device continues a playback of a playitem when a clip file being referred to by the current sub-playitem has been downloaded and is in an Enable state in the local storage; and stops, by issuing a DataStarved event, the playback of the playitem when the clip file being referred to by the current sub-playitem is in a missing state or an invalid state in a recording medium.
