Abstract
Aiming to facilitate the use of flash memory for video caching in content delivery systems, this thesis presents a set of orthogonal design techniques that leverage the characteristics of video coding to optimize flash memory fault tolerance. Motivated by the observation that general-purpose flash-based storage devices provide a finer-than-necessary data access granularity for video storage, this thesis presents a more flexible ECC (error correction coding) scheme to improve the lifetime of flash-based video storage. On the other hand, this thesis further explores control-stream assisted transcoding strategy to reduce the video data storage space overhead. Moreover, a reliability-aware data placement strategy is presented to further eliminate the storage overhead of control stream. The developed techniques can improve the overall lifetime of flash
