Storage method for loss-tolerant data stream recording

Abstract

A distributed storage of sequential video frames is designed without compromising data reliability. Capitalizing on the loss-tolerant nature of video data, user experience is maintained by leveraging higher capacity drives with lower latency, higher throughput and more efficient utilization of provisioned storage. No RAID, replication or erasure computations are necessary. There are a few optimization to this method which improves reliability, such as reliably storing video data in partitioned drives, making data storage configuration map known to each partition, implementing a strategy for avoiding loss of a common moment, preventing potential loss of reference frames, leveraging different sized drives, avoiding pitfalls associated with data getting stored disproportionately to large drives etc. Though video streaming data has been used as an illustrative example of loss-tolerant data, the methods and systems can be applied to any type of loss-tolerant data.
