Method of presenting multimedia data in a desired form by comparing and replacing a user template model with analogous portions of a system

摘要

Multimedia data in an object structure include entity objects and relation objects, wherein each entity object has data representing a media element as internal data, and each relation object represents a relation between the entity objects. A relation object is searched according to information specified by a search command, and a searched relation object and internal data of an entity object related thereto are displayed on the screen of a display unit as a set of display elements. To generate a digest of the multimedia data, a matching between a structure portion of a user model and a structure portion of a system model is examined. The user model is generated according to a request of the user and arranged in layers, while the system model has been previously generated. The multimedia data are arranged in layers according to the importance of respective data elements constituting the multimedia data. According to an examination result, a user model structure portion is selectively replaced by a system model structure portion, and the replaced user model is adjusted so as to display the same.
