SYSTEM AND METHOD FOR PRE-LOADING STILL IMAGERY DATA IN AN INTERACTIVE MULTIMEDIA PRESENTATION ENVIRONMENT

摘要

A system and a method for efficiently pre-loading still imagery data in an interactive presentation environment. A database is organized into a plurali ty of records. Each record refers to one of a video file, a still image file, and a user record. Each video file is logically associated with at least one image file and at least one user record. A selection of one such video file is processed. The selected video file record is retrieved from the database. Each user record associated with the selected video file is also retrieved. The user record i s updated to reflect the selection of the selected video file. The images file s logically associated with the selected video file are pre-loaded. Each still image file associated with the selected video file is iteratively retrieved and downloaded into a cache. A signal is generated upon completion of the iterative retriev al of substantially all of the still image files associated with the selected vide o file. The selected video file is played back within the interactive presentation environment responsive to the completion signal. The cached still image files are displayed in synchronization with the playback.
