Abstract (en)

[origin: WO2005018234A1] For use in media communications, e.g. in the delivery of video and audio or in teleconferencing, a media file or title is partitioned for secured, efficient delivery. A data sequence representing the file is partitioned into smaller subsequences, with a first subsequence being chosen to convey a degraded-quality representation of the data, and the other sequences for Complementing the first subsequence to obtain a superior-quality representation. Among areas of applicability are media on demand, real-time communications and broadcasting, and online media locker, jukebox and chat room services.
