Abstract

Data defining pages and objects of a multimedia work are transferred in the background to minimize delays that would otherwise be incurred. In playing a multimedia work that is recorded on a CD-ROM, a personal computer (10) that includes a central processing using (CPU) (23) transfers data for selected pages and for objects on a page of the multimedia work into a cache, using free CPU cycles, so that the data are available when needed. This technique is particularly useful in transferring data for animation objects of a multimedia work, since it enables two animations to play concurrently without incurring a delay to load the data for the second animation when the page is loaded and avoids interrupting the execution of the first animation at the time that the second animation must start executing. An authoring program used to create the multimedia work enables the author to select the pages and objects on a page that are to be prewarmed in this manner.
