Information storage medium storing graphic data and apparatus and method of processing the graphic data
First Claim
1. A method for processing graphic data using a graphic data processing apparatus, the method comprising:
- reading data from an information storage medium, the data comprising a display set comprising an object segment and a composition segment, the object segment comprising graphic object data defining a graphic object to be used in composing a graphic screen to be displayed on a display device, the object segment further comprising time information indicating a time when the graphic object data is to be stored, the composition segment comprising composition information for the graphic object defined by the graphic object data to be used in composing the graphic screen, the composition information specifying how the graphic object is to be displayed on the graphic screen;
storing, using the graphic data processing apparatus, the graphic object data at the time indicated by the time information of the object segment, the graphic object data being stored for a predetermined time so that the graphic object data remains available for use for the predetermined time;
storing, using the graphic data processing apparatus, the composition information; and
outputting, using the graphic data processing apparatus, the graphic object data according to the composition information;
wherein the composition information comprises time information indicating an output time when the stored graphic object data is to be output to the display device.

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.

3. A method for processing graphic data using a graphic data processing apparatus, the method comprising:
-
reading data from an information storage medium, the data comprising a display set comprising an object segment and a composition segment, the object segment comprising graphic object data defining a graphic object to be used in composing graphic screen data to be displayed on a display device, and time information indicating a time when the object segment is to be decoded, the composition segment comprising composition information for the graphic object defined by the graphic object data to be used in composing the graphic screen data, the composition information comprising location information indicating that the graphic object is to be located on a graphic screen produced by displaying the graphic screen data on the display device; decoding, using the graphic data processing apparatus, the object segment according to the time indicated by the time information of the object segment to obtain decoded graphic object data; storing, using the graphic data processing apparatus, the decoded graphic object data in a first buffer, the decoded graphic object data being stored for a predetermined time so that the graphic object data remains available for use for the predetermined time; storing, using the graphic data processing apparatus, the composition information in a second buffer; and outputting, using the graphic data processing apparatus, the graphic screen data composed using the decoded graphic object data and the composition information; wherein the composition segment further comprises time information indicating an output time when the graphic screen data is to be output to the display device.
