Abstract: A system and method for performing variable speed scanning or browsing, wherein a user controls the playout speed of a movie, which does not require additional disk or network bandwidth resources. In a preferred embodiment, the method provides for scanning operations for an MPEG video stream. The method satisfies the constraints of the MPEG decoder (in t he users set-top box) and require a minimum of additional system resources. The embodiments of the present invention include (a) a storage method, (b1) a segment sampling method, (b2) a segment placement method, and (c) a playout method, where (b1) and (b2) are two alternatives for segme nt selection. Thus, two sets of solutions are provided to support variable speed scanning in a disk- array-based video server: One using (a), (b1) and (c), and the other using (a), (b2) and (c).
