Method of controlling information in multimedia system
First Claim
1. A method of controlling information in a multimedia system including a processing unit, a storage, a display, and an input device, the system executing the steps of:
- storing, in a first area of said storage, for each of a plurality of screen layout areas simultaneously used by the processing unit, screen layout data including an identifier of each of a plurality. Of media information elements used in the screen layout area;
storing element data of said media information elements used in the plural screen layout areas in a second area of said storage, said element data being constituted with data representing a media information element and a reference number denoting a number of screen layout areas referencing the media information element corresponding to said each element data;
adding in the first area of said storage, in response to a command requesting a copy of a media information element inputted via the input device, an identifier of the media information element to be copied to screen layout data associated with a destination screen layout area, and incrementing, in the second area of said storage, a reference number of the element data corresponding to the media information to be copied;
in response to a command inputted via the input device to change one of same media information elements simultaneously used, copying element data associated with a media information element to be changed in the second area of said storage so as to use copied element data as element data of the media information element to be changed;
decrementing, in the second area of said storage, a reference number in element data associated with a media information element as a change source;
changing, in the first area of said storage, an identifier of the media information element to be changed in a screen layout data associated with a screen layout as an object of change to have a new identifier;
initializing, in the second area of said storage, a reference number as "one" in element data associated with the media information element as the change object;
changing the media information as the change object; and
presenting, for each of the plural screen layout areas, the media information elements related thereto according to data stored in the storage.

Abstract
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.
