Robust Distributed Storage of Digital Cinema Contents

In this paper we propose a multiple- description-based distributed system in order to store digital cinema contents in distribution centers and in theaters. Different representations of the high quality version of a movie are stored in a decentralized system to allow both data redundancy in case of server breakdowns and efficient and fast distribution of video content. Independent and mutually refinable representations of the movie, compliant with Part 3 of JPEG 2000 standard, are generated. These can be used autonomously in case of damage of a portion of the content or mixed together for traditional high-quality screening.
