Parity Stream Construction Method Based on Estimated Utility for Multi-Server Video Streaming System
In this paper, the authors propose a parity stream construction method that exploits multiple video streams. In this construction, estimated utility of parity data is considered. The proposed method gives priority to each data of multiple streams in terms of recovery from packet losses, and it is designed for recovering important data with higher probability. The priority of each data is set based on both inherent importance within a stream and loss probabilities of multiple streams. Specifically, this method deals with the data of less received streams as the important data.
