OPTIMIZATION OF STORED VIDEO DATA

摘要

An optimization method for reducing the amount of storage space on a storage device occupied by previously recorded video programming includes dividing each video recording into a plurality of groups of pictures (GOP's), identifying repetitive ones of the plurality of GOP's, assigning a unique reference designation to identify like repetitive ones of said GOP's, retaining on the storage device the first occurring ones of the GOP's that are repetitive, and replacing on the storage device each one of the subsequent repetitive ones of the plurality of GOP's with their respective reference designation.
