Abstract

See full text

For each media information element constituting a display screen image in a multimedia system, main data and attribute data are stored in a storage. After the user copies a media information element from a screen layout to another screen layout, until an attribute of the media information element is altered in either one of the layouts, the main data and/or the attribute data of the media information element is not copied in the storage of the system. Moreover, when the user varies an attribute of a media information element in one of the layouts, only attribute data of the media information element is changed in the storage. The media information includes music pieces and voices in addition to characters and graphic images.
