Title:
METHOD AND SYSTEM FOR DATA REPETITION BETWEEN LOGICALLY SUCCESSIVE CLUSTERS
Document Type and Number:
WIPO Patent Application WO1997003405
Kind Code:
A3
Abstract:
In a multimedia system, such as a video-on-demand server, a file with data is stored in a series of successive clusters which may be distributed across the disc. A cluster consists of physically successive sectors which can be read in blocks by a user application. By repeating a part of the data at the end of a cluster at the beginning of the next cluster, the system enables reading of a block of sectors from an arbitrary sector, said block and the subsequent blocks nevertheless being accessible by way of one seek operation. The interactive response time is thus substantially improved in situations in which the user requests an arbitrary data fragment.
