ABSTRACT:
A system for eliminating access time in CD-ROM based interactive video applications. A CD-ROM disc is formatted with multiple interleaved animation sequences. During playback, a user is able to select a sequence as the current sequence. Only those frames corresponding to the current sequence are displayed while other frames are dropped. The interleaved pattern of frames allows multiple sequences to be available from the CD-ROM drive without requiring repositioning of the CD-ROM drive's read head thereby eliminating access time. Specific patterns of interleaving that advantageously improve interactivity of an interactive production are described. A frame buffering implementation is described.
