This paper presents a novel data placement and retrieving scheme or real-time multimedia stream playback via a scalable storage system. The multimedia streams are contiguous data packets which may be representing video, audio, or other media be retrieved simultaneously from a storage system on a real-time and on-demand basis, The major challenge in implementing the system is the support of simultaneously retrieving a big number of streams from a large-capacity storage system. This bottleneck

The proposed scheme efftciently reduces the seeking time by a very simple placement method and a retrieval scheduler and, in the mean time, continuous playback of multiple real-time streams and a scalable storage capacity are both achieved. Performance valuation of the proposed scheme is provided through theoretical analysis and experimental measure.
