Abstract

An information storage medium including graphic data and presentation information, and an apparatus and method of processing the graphic data are provided. The information storage medium includes the graphic data, page composition information which defines page composition of the graphic data, and the presentation information indicating when graphic screen data, which is composed with reference to the page composition information of the graphic data, is output to a display screen. Therefore, a graphic object is reusable in graphic data processing, and accordingly, a time taken to process the graphic data is reducible and memory area may be saved.

Claims

1. A method of processing graphic data, the method comprising:

storing a plurality of graphic object data each defining a respective graphic object for a predetermined time so that the plurality of graphic object data remain available for use for the predetermined time, the plurality of graphic object data thereby defining a plurality of graphic objects;

storing composition information for at least one of the plurality of graphic objects defined by the stored plurality of graphic object data, the composition information specifying how the at least one of the plurality of graphic objects is to be displayed on a display device, and comprising information specifying which ones of the plurality of graphic objects are to be displayed on the display device;

storing composed graphic data to be output to the display device, the composed graphic data being composed from at least one of the stored plurality of graphic object data according to the stored composition information;

outputting the composed graphic data according to the stored composition information;

receiving a new graphic object data defining a new graphic object; and

updating one of the stored plurality of graphic object data using the new graphic object data.

2. The method of claim 1, wherein each of the plurality of graphic object data is identified by a respective object identifier.

3. The method of claim 2, wherein the new graphic object data is identified by an object identifier that is the same as the object identifier identifying the one of the stored plurality of graphic object data that is to be updated using the new graphic object data.

4. The method of claim 3, wherein the updating comprises replacing the one of the stored plurality of graphic object data with the new graphic object data.
