“…This method maximizes the overall quality by assigning appropriate traffic volume per path and FEC redundancy for whole content based on its bandwidth and packet loss rate. Han et al proposed a use of fountain code with path diversity in [8]. Fountain code generates arbitrary number of encoded symbols from finite number of source symbols.…”

In this paper, we propose a video data recovery method that exploits multiple streams. The proposed method gives priority to each data of multiple streams in terms of recovery from packet loss, and it is designed for recovering important data with higher probability. The priority of each data is calculated based on both inherent importance in one stream and loss probabilities of multiple streams. Specifically, this method deals with the data of less received streams as the important data. Moreover, the proposed method decides appropriate number of parity packets. This is because the transmission of too many parity packets might affect the other traffic, while that of too few packets might recover insufficient amount of data. The proposed method can improve video quality of total multiple streams.Our simulation results show that the proposed method can recover more important data with higher probability. Furthermore, the proposed method can also achieve almost the same restoration ratio among streams of recovery targets.

“…Han et al propose a rateless code with path diversity in [7]. Since recovery capability depends on only the number of received symbols in rateless code, this method can deal with multiple paths which have different loss characteristics as one virtual path without complex rate control.…”

In this paper, we 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. Moreover, we focus on the creation method of redundant data to be transferred from another server for multiple worse conditioned streams, which greatly affects the recovery capability, and propose the creation method which is less influenced from the network condition.Our simulation results show that the proposed method can recover more important data with higher probability. Furthermore, the proposed method can also achieve almost the same restoration ratio among streams of recovery targets which have different loss probabilities.
