METHOD FOR CODING A PRESENTATION

摘要

A coded presentation (302) comprises a number of sub-presentations (304, 306), each comprising a number of presentation elements (308-312, 314-317). A presentation element is an elementary part that is to be presented and comprises text, audio, video or an image. A sub-presentation (304) has an interface (318) that provides a reference for the presentation elements (308-312) in that sub-presentation. This reference can relate to timing aspects and to locations aspects relevant during play out, and to a priority as to whether or not the sub-presentation is to be played out.
